Yes I know that people seem to successfully ignore the load range. I found some Avon tires that were correct for the load. They were expensive and didn't last long. They also didn't like inner tubes. You must use radial tubes and even those are iffy. If your new tires have what look like harmless paper stickers on the inside, be sure to remove them and every trace of the glue. Otherwise the tube will fail ... guaranteed. Then, use talcum powder between the tube and the tire. Bias ply: I like these tires better than the radials since it is easy to get the load range, they are inexpensive, ride well, and start to groan and slip slowly when stressed rather than break away without warning as radials do. These are the OEM tires for our vans. My only complaint is that some take a set when parked for a while and thump along for a couple of miles afterward. I bought my last set, Cheng Shin, from Premier Tire (in Denver, I think) for $32 each. Ed Parsil from the Subaru 360 Drivers Club gave me a hint about tubes for these tires. If you can't find the right ones, just use 10 inch motor scooter tubes, probably 10 X 3.50. These are widely available with right angle stems and stretch easily to fit our larger tires. I haven't had any flats with these tubes and tires. I can't say that for the radials. Old Tires: I don't think that there is any issue unless they were stored in the sun. The rubber might look a little grey, but if there are no cracks, they should be OK. Thanks, ------------------------------------

Hi Dave, Tires: 5.00-10-6PR ULT (Ultra Light Truck ?)according to the shop manual. I have AVON 145R10 C 8 Ply VAN STEEL Europe Radial tires 82/80N 65 psi rated for 1100 pounds max load. Coker Tire may have Michelin MX 145R10 and other manufacturers. Mini Mania site may also have other 10 inch tires. --------------------------------------By Michael Radtke on Wednesday, November 29, 2000 - 08:03 pm: Hello, I need tires and tubes for my 1979 ElectraVan. Avon makes a 145R10C which should do since I need a 965 lb. load capability. However, no one in the USA is willing to import them for me. Would some kind soul like to buy the set and put it on a British Airways direct flight from London to Phoenix? I understand "space available" freight is quite reasonable.

I called Mini-Mania (turns out they're about a hour's drive away), and right now they have, in stock, only the Camac brand tires in the 145SR10 size, plus a few other brands in 165SR10. They buy the tire direct from England, and have different brands available at different times. If you need an odd size (e.g.-a car that is still being sold or driven in England!), you might want to check their site (http://www.minimania.com/) or e-mail them for availability.

-------------------------------------------------------------------> Mike when I got the bus several years ago it needed tires bad. I got Michelin tires locally for $100.00 each! These only lasted 6000 klm. Next I got Falken SN807 from Talon Tire.( http://www.talontire.com/ ) $42.00 each. These seem much better. Ride , handling , and quite. I run the tires at max pressure. These are 44 psi. The Dunlops are 220 ah. I am working on a deal to get a 120 volt set of nicads. If this dose not play out I will get a set of GC4 Exides. Rob. ----------------------------------------------------------------------Hello, Many of you responded about my tire search for my ElectraVan. Thanks for that and thanks for the general discussion as well. However, I still haven't sorted it all out and would welcome any additional advice. Here are some points: 1) I cannot easily change rims to a more available tire size since these split rims bolt to the edges of the brake drum and have zero offset.

2) My current bias ply tires get hot at the owner's manual recommended pressure of 45 psi. The front: only the tread gets hot; the rear: both the tread and sidewalls get hot. 3) My current tires are 20 years old. I swapped them around and included the spare which has none of the checking and cracking that the other tires do. All the tires still get hot in the same way as in #2. 4) I compared the rolling distance with my VW Vanagon. Starting at the same speed, the Vanagon rolled twice the distance that the ElectraVan rolled. 5) I put 50 psi in the tires. They now run warm rather than hot, but still have the same heating pattern mentioned in #2. I haven't measured the rolling distance, but I would guess that it is now about 2/3 of the Vanagon's. I have searched around and this is my pick of tires: a) I could use 145R10 passenger tires rated at about 750 lbs. capacity. I should have 965 lbs. according to the door sticker. These tires are cheap. Most folks driving ElectraVans seem to use these tires without incident. Kumho and Falken are typical brands. (Michelin/Riken makes a similar rated tire at a much higher price.) b) I could use 5.00X10 bias ply tires from Cheng Shin. 960 lbs. at 50 psi and are most like the originals. about $50 each.

These carry They are

c) I could use 145R10C Avon "Europe Van" tires. These support 990 lbs. at 65 psi. These are about $100 each after shipping from the UK, assuming that I can get them by US customs lacking DOT approval. I have read on this list that inflating tires over the sidewall pressure is OK for EV's because of lower top speed; 50 mph in my case. If this gives an increase in load capacity, then #a might be a good choice because it offers low rolling resistance and no ElectraVan owners have reported their tires popping. I am afraid that going with #b will still make for high rolling resistance and hot tires. But maybe my current tires get hot because they are 20 years old. #c seems to be the best choice, but my $400 worth of tyres may get confiscated by US customs. I have determined that if this happens that it will be entirely my problem. Your thoughts please. Thanks, Mike Phoenix AZ USA -------------------------------------------->Mike I do not think your rolling test between the VW and the Jet Bus has

any meaning. There are too many variables. Brake drag , wheel bearing grease , wheel seal age and condition, drag in the trans., wheel alinement, size of tire, just to name a few. A more accurate test would be to measurer the Jet Bus power consumption per mile with different tires. All other parameters would need to be the same. Weather, load, speed, etc. I also think you are looking for a tire with too high a load capacity. The Jet weighs 2690 lbs. Divided by 4 is 672.50 plus driver ( in my case 130 lbs ) is total 705 lbs per tire. I know this leave little for cargo but how much do you need to carry? I have driven my Jet bus about 20,000 klm on Michelin and Falken tires without a problem. ( I like the Falken tire much better ) You are over concerned about the tire temp. Mine run about 165 degrees an a hot day after a hard run. Hope this helps. Rob. -From: "Michael A. Radtke" <[email protected]> Subject: Re: More: Rolling Resistance Comments: To: EV600-L -- Jet ElectraVan 600 Owners List <[email protected]> Rob, I am getting the weight requirement off of the door sticker. 6 ply bias ply tires similar to the original have a 960 lb. rating, so I think that I am on track. At 45 psi. on my original tires, I get home with about 30% charge left after my commute. With 50 psi, I get home with 50% charge left. I ordered the Avon 145R10C tires yesterday. I'll post again when I get some experience with them. Thanks for your comments. Mike > --------------------------------------------------->Is the camber causing tire wear? > Yes! I only get 4000 klm on rear tires. Only toe is adjustable on the rear. The manual calls for +1 to 3 degrees camber. My camber gauge reads to 6 degrees and I am off the scale I bought a set of rear control arms but they did not help. I am having some angle shims made to install between the rear axial housing and the control arms. This should fix the problem.

Rob, In the process of replacing my tires, I aligned the front end and set the ride height (posture). I found the car quite low and after I set the new height, it looks like the rear has excessive camber. However, the height is in spec now. (I found the 145R10's 1/2 inch lower than the 500X10's, so I reduced the target posture heights by 1/2). I expect that the rear camber is supposed to be that way since I don't think that its adjustable. Is the camber causing tire wear?

Well, My Avon tyres arrived and I've been driving on them for about 3 weeks now. I have some observations to share. 1) These tyres are rated at 65 psi. However, with the wheels off the car, the rims start to bend at about 50 psi. At 65 psi, I don't believe that there is a personal hazard, but it is easy to visualize the tube squirting down the crack in the rim and blowing out. When the wheels are mounted on the car there is no problem since the rims have 4 additional bolts clamping them together. 2) I have tried driving the car at 65 psi and 55 psi. I cannot sense any difference in tire temperature, but the 55 psi seems to have _less_ rolling resistance than the 65 psi. At either pressure, I get at least a 5% increase in range over the bias ply tires that I replaced. 3) $400 for tires, tubes and shipping is no bargain. I still wish that I could get a tire engineer's advice on overrating the Kumho 145R10 for use at speeds less than 50 mph. I know that at least one of the list members has done this without incident. Thanks Rob & Bill for your help and advice. Mike Phoenix, AZ --Robb, Those liners are called flaps and their express purpose is to prevent chafing caused by rust. I labored over whether I should install them or not. In the end, I didn't since I couldn't find any ready made ones for 10 inch rims and my car had original tires which had never been removed from the rims and didn't have them. I did shine up and paint the rims so their surfaces are smooth and in Phoenix they are not likely to rust. Mike ---------From: Mike Radtke[SMTP:[email protected]]

I had one tube fail due to "squirting down the crack" when I removed the wheel before lowering the pressure (Thanks for the RTFM warning Bill -- Important point). I also noticed a lot of rust flakes and general crud collection along that crack and grinding into the tube. My solution was to install a liner -essentially a big rubber band that fits in the rim and covers the crack before the tube goes in. I made my liners from 4" wide rubber cut from old tubes. Bicycle tires have the same thing, used to protect the tube from the spoke ends. Robb 3

Back to: Top of message | Previous page | Main EV600-L page -------------------------Comments: To: "[email protected]" <[email protected]> Hi Bill, etc. Please don't yell at me about not reading the manual. What makes you think that I even have a manual? Well, actually, I do. To the best of my knowledge, my owner's manual does not say anything about a maximum pressure for removing a wheel. I just re-checked. My manual has no date. It is about 14X22 mm with a red cover. Owner's manual, Electra Van, and Model 600 appear on the front, the Jet Industries address on the back. I do thank you for the heads up though and I will follow your advice about the 20 psi maximum wheel removal pressure. Thanks, Mike ---------==================== ----------------------------------------------------"The Rim/Tread width relationship is more complex than that. For a start the quoted width is the nominal tyre width, which can differ from the tread width by quite a bit, usually the tread width is narrower than the tyre width. Consider that 145mm is much wider than the 3.5" (approx 89mm), and yet the ideal rim size for a 145R10 tyre is a 3.5B10. Any tyre is designed to fit a particular ideal rim size, with a range of permitted rims thrown in. The only way to know for sure is to check out the manufacturer's specs. Some manufacturers/importers are really cagey and will only advise a single rim size, other's are not so bothered and quote permitted rim sizes. There are others who are so touchy about this that they will only quote for a given completely standard car." --Coker Tire: The Number One outfit for all vintage automobile tires.

though.) There is a caveat you need to be aware of in relation to tires and Subaru 360's though: The only 10" tires that I've been able to find on the regular market (i.e. tire stores) are 145's. The 360 was designed 130's (or 4.80's.) 145's don't fit in the spare tire spot but work fine on the wheels. Your best bet may be to get 4 145's from whereever and 1 4.80 from Coker so you have something that will go into the spare tire spot. --

The main problem was initially getting the bead of the tyre down into the well. I did that by fully deflating the tyre and then carefully driving over the side-wall of the tyre whilst the wheel was lying flat. The weight of the car pushed the bead out of its' seat. Once that had been done, actually getting the tyre off the wheel was very easy. Getting the tyre onto the new wheel was also easy and by 'bouncing' the tyre once it was on the new wheel, it seated sufficiently well to allow me to inflate it using a foot pump. Kev -not sure how to say this really do any of you have any idea of how dangerous inflating tyres is?

have any of you read the sidewalls? why are all tyre fitters trained? do you know why you should listen to the tyre as it inflates? have you ever seen what happens to a wheel/tyre assembly when the tyre fails? and how far it travels even when only inflated to 25/30 Psi. take your tyres to reasonable independant garage who will normally only charge valve and balance often less than 25 quid for a set of 4 wheels. have a care have fun ps not trying to be patronising but have seen many really nasty accidents involving tyres and heard of many more, yes i am in the trade Reply -> do you know why you should listen to the tyre as it inflates? Yes - it 'pops' as the bead seats. > have you ever seen what happens to a wheel/tyre assembly when the tyre > fails? -> and how far it travels even when only inflated to 25/30 Psi. No, please tell us. Of course you should inflate your tyres inside a cage - but I've yet to see a 'professional' fitter use one. -Sigurd Mar 18 2002, 6:40 am show options Newsgroups: alt.autos.antique From: "Sigurd" <[email protected]> - Find messages by this author Date: Mon, 18 Mar 2002 15:41:23 +0100 Local: Mon, Mar 18 2002 6:41 am Subject: Tires for oldtimers Reply | Reply to Author | Forward | Print | Individual Message | Show original | Report Abuse Hi NG, I've found a distributor for tires and rims for oldtimers.

-Tubeless versus Tubes, the whole story, and then some 54- section6.htm This article will deal, in much more depth, information about using tubes, or not, and the types of rims, etc., than in various other places on this website. This business about tubeless tires, tubes, etc., is confusing to many folks. 1. Except for airheads that came from the factory with tubeless tires, most all others came from the BMW factory with tubes and the rims have WM-2 shapes. That is a particular shape of primarily the inside of the rim. The WM2 shape does not have the 5 degree angle increase of the tubeless rims...on the bottom area and side area...that the tire bead rests against. This WM2 shape in general has a contour in the middle and angles outward from the middle, and where the tire bead contacts, that is FOR USE WITH TUBES. Some BMW rims are also 'safety rims'...which help to keep the tire onto the rim, and NOT towards the interior. The other commonly used rim shape for use WITH TUBES is the CP contour...which was also used in some later BMW models...and also is FOR USE WITH TUBES. This shape has a more pronounced drop center, and the horizontal part that the bead ending fits has a 4 degree slope. That is OPPOSITE the TUBELESS rim shape!! 2. BOTH the CP and the WM are for use WITH tubes. 3. While the rims CP and WM are for use WITH tubes, they ARE OK to be used with most tires that are marked TUBELESS. Those tires have a bead, etc., that IS compatible with those CP and WM rims. That does NOT mean it is OK to run tubeless marked tires on these rims withOUT tubes. MANY DO and HAVE, safely. YOU ARE ON YOUR OWN if you do. 4. There are other rim shapes, such as MT and MTH2, suitable for tubes or not tubes. These types of rim shapes WERE used on some Airheads: R80GS (NOT G/S); R80R; R100R. The R80GS has had both these types depending on the year. The R80 and R80RT from 1985 (yep, the year BMW went to the 'not serviceable except to replace them' type of front wheel bearings); late R65, R100RS and R100RT...all phased in in 1986 and 1987..all had the MT-2 version of these rims. As you all probably know, these wire-spoke wheels had a new, clever, BMW design in how the spokes were fitted, so that the spokes were OUTside the air cavity. The MT and MTH2 rims are different. The part meeting the sidewall of the bead is pretty much the same (in fact the part of ALL the rims mentioned in this posting

are pretty much the same where they meet the side of the bead, except that angle).... BUT, on the MT, which is specifically designed to allow the use of tubeless tires without tubes (but CAN be used with tubes), the horizontal part of the rim is 5 degrees UPward, tending to hold the tubeless tire onto the rim. The MTH2 not only has that 5 degrees, but there is a BUMP in the rim shape, upwards, that is inwards, just before the drop center area. THAT tends to keep the tire bead from dropping into the center of the rim. That bump has TWO functions, one is to help in putting air into the tire, and the other is to help DEcrease very fast air dropping upon a serious bump, or whatever. The WM2 does not have that 5 degree change. OK...now that you have plowed through and read all that, here is the bottom line, plus touching on things NOT talked about above. AGAIN, I caution you that this is MY interpretation of things: 1. You are SUPPOSED to use tubes on the airheads that came with tubes. If you use a tubeless tire, and add a tube, you should REDUCE the speed rating by one step. NEVER fail to use tire talc when installing a tube....rub it all over the tube and inside of the tire. 2. Almost all tires marked tubeless, are OK for use WITH tubes. SERIOUS exceptions MAY exist in trying to use RADIAL tires. You generally will not find radials that fit your Airhead anyway. 3. Tires marked Tubeless are specially made to ensure they hold air. Tires not so marked will often loose air, as they are porous....one area or another. It is UNclear if many tube only tires really can be used long term and not loose air. 3. Use of tires marked tubeless, WITH tubes, reduces its speed rating, by ONE category. When installing a tube, do NOT leave the mounting nut against the rim. You could have the tube fail to release air from between the tube and inside of the tire....which it is SUPPOSED to do, normally, in use...and the tube will chaff, and fail early. Run the nut up against the cap, or throw it away, or put it in your tool tray....it is part of the tubes you purchase strictly to HELP in installing the tube. 4. Use of tubes causes the tire to heat up more, reducing tread life, and that is ONE of the reasons for the speed rating change. 5. The SAFEST thing to do, considering big bumps/potholes/objects in the road, is to use the wheel as BMW intended. Because of the mixture of wheels BMW has used, and the way wheels bend (or crack!) in serious 'hits', no hard and fast rules that fit all situations are possible. If you are willing to understand, AMONGST OTHER THINGS, that a fast air release is possible on a flat occurring ...or upon a rim bending bump or chuckhole, and don't mind that...then, it is your choice, with that knowledge...to not use a tube. 6. It IS possible for the snowflakes to be converted to use tubeless marked tires withOUT using tubes. Some few snowflakes are porous, but that is fairly rare, most will hold air just fine. ONE method involves enlarging the stem hole, and possibly spot facing the inside of the rim slightly. That allows small tire rubber tubeless stems to be fitted. This has been done many times, without any known...to ME...problems. However, this is NOT as safe as using tubes. That does NOT mean it is totally UNsafe. Folks have done considerable racing with tubeless converted snowflakes. see #7 just below. 7. One of the little known facts is that as tires rotate at high speed, the forces tend to OPEN the valve stem core, and valve stem cores are manufactured short, long, and short with a red band. The red band valve core is designed to not have this high speed problem. It occurs at speeds for that well above what you can attain on a stock airhead. HOWEVER, there have been instances of weak valve stem core units that leaked air. A short valve core, and a sealing cap, is usually just fine for us. The long core, and no cap, is not a great idea...you MAY loose air very slowly. ALWAYS use a CAP on the stem...one that SEALS.

NOTE: BMW sells a special METAL valve stem, that comes with nut, metal cap, AND A STEM RUBBER O-RING, under part number 36-32-1-452-748, about $4.. This will fit in the snowflake hole...but you will want to be sure the inside area is worked over a bit to ensure a very positive air sealing. This is a VERY nice way to do the conversion to tubeless. That chromed steel valve assembly is available elsewhere's, at about half price. It is, bottom line, YOUR choice. Snowflake rims used as tubeless may release air, or the side of the tire, depending on circumstances, such as puncture, or huge pothole and bent rim.....unpleasantly. Some rims are slightly porous. Then, again, air is released fairly fast on tubed snowflakes (unless the stem is sealed with rubber pieces....and a nut and washer....another story in itself)....and there is a possibility of tire rotation on the rim possibly ripping the tube to pieces....(see #9 below). The convenience of a roadside repair may convince some to go to a tubeless conversion. It is a mixed bag. Snowbum has never converted his snowflake rims....but, to be honest...Snowbum MAY convert his sidecar tug's snowflakes...he is being wishy-washy about it right now....and is not even sure if he might not also do his solo RT that way too. There is NO question that the snowflake wheels shape allows them to handle major rim denting and still hold air, if tubes are installed as they were designed to be. NOTE!....when a snowflake (or other wheel, WM or CP) is used withOUT a tube, you MIGHT have problems trying to get it to hold air during a tire change....if the tire bead does not stay in full, all-around, contact with the rim, in the instance of a flat tire. That is why tire folks use a BAND (or rope!) around the rim of the tire, to squeeze the tire to the sidewall....and one goodly reason I don't even consider carrying those high pressure steel CO2 mini-bottles that are in some tire repair kits. I prefer a piston-cylinder operated, or battery operated pump....UNlimited air!...you can grab the tire or use a rope on it...and get it inflated. Sidecar folks sometimes use rear tires on the front of the tug, with the directional arrow, if present, reversed. This is acceptable practice. 8. It is possible to seal the tube stem via rubber washers and exterior nut to the rim to hold air better, if the tire/tube is punctured. But, that must be offset with the knowledge that if the tire rotates any on the rim, it will rip the stem out of the tube. 9. The tube nut is for installing the tube, then to be NOT used (see #8 though)....or to be up against the valve CAP, NOT the rim. As you can see, it is a mixed bag. -----------------More Tire Tips Baby powder is not just for a baby's [or bicyclist's] bottom By Mike Munk, LAB, EC Instructor July 2000 Wheel Issues

In a recent past article I listed 11 tips on how to avoid flats I was reviewing that article last week when I noticed a glaring omission ...baby powder. I know that may not sound so important, but it probably ranks right up there with the best of the others. Every time I buy a new tube, I take it out of the box and give it a good going over with baby powder (or you can spend 3 times the money on a product called "tire talc" but it's basically the same thing without the nice smell). Then I refold the tube and put it in a protective covering (either back in the box, or wrapped in a piece of cloth). Here are some good reasons why it's important to powder your tubes before you put them in the tire. 1. Allows easier installation-Ever had trouble getting the tube to go inside the tire because the rubber tended to be tacky or sticky? Well, the powder allows the tube to slide completely into the rim and tire much more easily without twisting or pinching. If the tube is not completely settled into the tire and rim it's subject to a pinch blowout upon inflation. Ever had a tire blow off the rim after you'd spent 15 minutes changing it? Bummer huh? 2. Allows the tire and tube to work independently-This is very important because after you inflate the tube inside the tire it will have a small amount of twist to it. Powdering the tube allows the tube to align itself inside the tire. It also keeps the tube from dragging the rim tape with it as it settles into its natural position. If the rim tape is moved from over the spoke holes you will have problems down the road . . . I promise. 3. Finally, it makes your hands smell nice after installation-What a plus here! You can use the cloth you used to wrap the tube for protection to clean your hands, and you will have the fresh smell of baby powder to titillate your senses as you continue to ride down the road One thing to remember if you powder your tube and you need to repair it. You will need to clean the area around the hole very well and rough it up with the supplied sandpaper to allow a good bond for the patch. The powder will sometimes interfere with the glue and prevent a good seal. A little preparation before you get on the road will go a long way in making your rides more trouble free and more pleasurable. I always say that if you're changing tires or having breakdowns on the road, you ain't having fun. ---------------Did U NO: Inner tube talc = French chalk = powdered soapstone? One of the most closely guarded, yet least interesting industrial secret formulae LOL. ---------------I am about to do my first tire change.

Remember to lubricate. keep a water spray bottle close by and keep the bead wet when prying on it. Get some good tire irons. The Motion pro tire spoons work great. Put a layer of duct tape over the spoke nipples on the inside of the rim. Good luck. try and avoid pinching the tube while putting it back together. Once again good luck. __________________ 2002 KTM 400EXC Reply With Quote -A couple big keys that I've learned over the years: 1. Partially Inflate tube, just enough to hold shape. THis helps to prevent pinches while installing. 2. Powder your tube with either tube talc or Baby powder. This helps prevent pinches later. 3. Lube the bead. Use liberal amounts of very soapy water. I mix my lube about 4:1 water to detergent. 4. When levering on the tire, NEVER bring the iron past vertical. IF you don't bring it past vertical, you can't pinch the tube. I personally set up my rims so that the rimlock and valve stem are close together. My rimlock is 4 spokes over from my stem. With it like this, I am able to start with the tube in the new tire and I can slip the rim with rimlock onto the first bead while at the same time inserting the valve stem into the rim. Once this is done, you can shove about half the bead onto the rim with just your hands (some dunlops I've put the whole first bead on w/o picking up an iron.) Next pick up the irons and start working the bead on. Once I get the first bead on, I lay the wheel down and spray down the second bead. I then start at the rimlock and lever the bead over on both sides of the rimlock being sure to depress the rimlock so the tire will slip under it. I then just start working my way around the tire taking small "bites". You want to end up so that the rim lock is 90-120 degrees away from the last part that needs to be levered on. This will allow you to keep the tire bead down in the center of the rim to give you the extra room to slip that last bit over. Lastly, inflate to seat the bead. HTH Rob ---

ong as it is not a radial. Tubes in tubeless radials are not reccomended. I believe this to be because the tube has a relatively large effect on the lightly constructed radial tyre and friction between the two can lead to overheating. Also the weight of the tube will alter the speed rating of the tyre, but as you are running a tube unsealing the bead slightly at warp factor 9 may not matter too much. ap--http://groupsbeta.google.com/group/rec.motorcycles/browse_thread/thread/6feffd33b65e265e/0fa7b2 f876d3f181?q=%22tube+type+rim%22&_done=%2Fgroups%3Fq%3D%22tube+type+rim%22%26hl%3D en%26lr%3D%26safe%3Doff%26sa%3DN%26tab%3Dwg%26&_doneTitle=Back+to+Search&&d#0fa7b2 f876d3f181 I don't know what the bias/radial thing is with tubes, but someone made a radial tube at one time.

Improper mounting can cause tire explosion and serious injury. Follow these mounting precautions: * Wear approved eye protection. * Clean and lubricate beads and rim. * Centralize rim band and tube to prevent pinching if tube-type rim. * *Note directional arrows on sidewall where applicable. Lock assembly on mounting machine or place in safety cage before inflating to seat beads. * Set air hose relief valve at 40 psi. * Use extension gauge and hose with clip-on air chuck. Stand back with no part of your body within the perimeter of the assembled tire and rim. * Inflate with core in valve stem. * Never inflate above 40 psi to seat beads.* * Spin wheel to check bead seating and alignment. *If the beads do not seat by 40 psi, deflate and repeat above procedures. Never use a volatile substance or rubber "donut" to aid bead seating. If the tire is a tube-type, deflate and reinflate after seating to prevent tube wrinkles.-http://64.233.167.104/search?q=cache:YXnwd_DnTcJ:www.motoshopper.com/s/specials/tires/tireinstall.htm+%22tube+type+rim%22& hl=en

---------------------------Congratulations Dave: I have a 1980 EV600 that I drive every day. My advice is to avoid the freeways and roads with limits over 55 mph. I insulated my battery compartments and installed a set of Optima 12 volt batteries. They limit my range to about 15 miles per charge but the lighter weight makes braking easier. Many of the vans this age have sticking brake wheel cylinders. the simple test for this problem is to jack up a wheel and have someone apply the brakes when the brake is released you should be able to spin the wheel by hand. If it is binding then a brake job is in order. You can usually just buy generic 15/16" brake seals at your local autoparts store. If the pads are worn you might have to find a local shop that relines brakes. Note you should change the brake fluid as it absorbs water over time and will rust the brake cylinders. ------------------------------------------------------Hello, I decided that it was about time to check the brake linings on my ElectraVan. While I found the front OK, I found one of the rear wheel cylinders leaking. I stumbled around trying to find a rebuild kit, but the Nabco cylinder uses a piston with a ring type seal rather than the usual cup type seal. The bore as I measured it was 3/4 inch and I found that documented in the archives as well. The archives also mentioned that a kit for this cylinder is difficult to find. So, I did a web search for kits. First, it is difficult to find a kit by bore size. It is easy to find one by vehicle, but not our vehicle. Second, even if you can find a ring type seal for the 3/4 bore, it seems that the inside diameter or thickness of the ring where it fits in the slot of the piston is even more difficult to match. This being said, I decided that perhaps I should just cut off the end of the piston and use a cup type seal. Another web search shows that others have done this with success.

My question is, do you see any down side to doing this? I'll post my results if you don't stop me from going down this path. Thanks, Mike ***** Well, no one tried to stop me ... I found that Omix-Ada had a part number A6133 (changing to 16724.01?) that was meant as a universal 3/4 inch wheel cylinder kit for a jeep. This kit seems available from many sources on the net. I was able to cross reference it to a NAPA UBP127 on the NAPA web site. My local NAPA disavowed any knowledge of that number, but were able to look it up by the Omix-Ada number. It came up with a NAPA number of UP127. The kit came with pistons as well as seals. At first, I thought that I might be able to adapt the new pistons, but modifying the old ones looked like a better plan. So, I hacksawed the ends off and smoothed the new surfaces with a file. I polished the inside of the wheel cylinder and put everything back together and it all works fine. I am confident that there is no safety issue, but perhaps the wheel cylinder will leak prematurely because of my modification. Reline the 4 brake shoes: $48 NAPA wheel cylinder kit 9 My labor Priceless Thanks, Mike

---------------------------Don I've redone the brakes in both of my electrovans. I havn't found many new parts. Hone the wheel cylinders and purchase the universal brake parts at a local autoparts store. If I remember correctly they are 15/16 inch. The size is cast on the outside of the cylinder. As far as brake drumbs mine all measured true and didn't need to even be turned the expert at the shop said this style with the split rims attached directly to the drumb seldom have problems because of the extra metal in the castings. He could have turned them but suggested a light hand sanding to brake the glaze and remove some surface rust. Be sure to change all of the brake fluid every few years and you shouldn't have problems with the brakes except of course as all Electrovan drivers will attest they are undredesigned for the extra weight of all those batteries --------------------

It's a must so they can get the arcing right along with clearances. Check your yellow pages. Do the swap NOW to DOT 5 fluid. The one thing is to get the cylinders really polished. They have to be super shiney to keep the DOT 5 fluid from seeping out. I used finer and ever finer polishing compound on a rag-and-stick setup until those cylinders I had looked like mirrors.

I've had mostly good luck with mine. the cylinder bores were worn so they weren't too straight. I honed them and then rubbed just a little graphite powder on the 'tops' of the cylinders, so when they were fully extended they wouldn't get cockeyed and stick. I had a theory that if the fluid leaked out of one,the other one extended farther than normal. I also installed some new springs. I found some NAPA parts that seems to be a good fit. They are a little unusual, but not impossible. WEhn mine stuck they were STUCK HARD! the van wouldn't even roll. I was burning grease and I think I warped a drum. Now, if it happens I know to just crawl under there and leak out some fluid and I'll get home. JERryu Stubbs --------------------Hi Mark, I have an electra van also, my van is a 1979 and I had a problem with the wheel cylinders sticking, that may be causing the heat in your drum/bearing area. Take the drum off and push the brake peddle, Have a helper do that for you while

you watch the wheel cylinder. Look for free movment. If the cylinder does not move freely you should remove the piston and clean it with emory cloth, then reasemble. It may be hard to get the piston out,I used the brake presure to push the pistons out, that in itself was hard but it worked. Hope this helps! Phil -Hi Mark, First off, Welcome to the realm of Electravan ownership. My own opinion of the brakes on these beasts cannot be repeated in polite company. No matter, it sounds like your RF brake shoes are adjusted too tight or the hydraulics are sticking. I recall also that someone came up with a source for rebuild kits for the wheel cyls. It is somewhere on this list's archives. Let us know what you find out. Thanks! Robert M. PS I'm curious to know what these vans sell for these days. -H Mark I own 2 electrovans and had the same brake problems. Don't look for a rebuild kit just go to your local auto parts store and get universal replacement cups (I think on the outside of the wheel cylinder it says 15/16) they work fine. I found several wheel cylinders with enough corrosion to make it hard to get them out. I polished the inside with 1200 grit wet or dry sandpaper. Note if they have been leaking the brake fluid is water soluable just rinse everything well in plain water. Replace all of the brake fluid in the vehicle to prevent further corrision in the brakes. I also use a pack of 8 Optima yellow top deep cycle batteries. It shaves hundreds of pounds off the vehicle weight which makes braking much easier. I only get about 25 mile range but it handles much better and the batteries are maintenance free. I tried 9 batteries it didn't increase the range much and made it to easy to cause the clutch to slip and only gained about 2mph on the top end speed. Have fun Norman Smith --

Hi Mark, Pardon me for taking this discussion on a slightly different tack, but I just wanted to remind the forum members that DOT3 brake fluid absorbs moisture (and I suppose there are other types that do as well). If it is in service long enough, it becomes saturated with water and at that point, things in brake system begin to corrode. Because of this, DOT3 brake fluid should be replaced regularly. I am guessing that this is what caused the problems you described below (not to mention similar problems I found with Electrovan when I bought it). The method I have seen recommended for dealing with this is to bleed the system until all of the old fluid has been replaced by new. Since this can be a time

consuming and frustrating job, I choose to take a half-way measure which is much easier and still seems to work well for me: I replace the fluid in the master cylinder reservoir every time I do the regular maintenance on the vehicle. I do this by using a turkey baster to suction the old brake fluid out of the reservoir and then I carefully wipe out any debris that has collected in the bottom using a lint free rag before refilling it with fresh fluid. I have noticed that the brake fluid becomes darker as it absorbs water. Before I started following the procedure I describe above, there were times where the brake fluid in my vehicles became the color of maple syrup. Now it never shows more than a yellow tinge. I suppose the big question here is, "How often should I do this?". With my internal combustion powered vehicles it gets done every time I change the oil. That works out to two to four times a year. I suppose this is more often than it is really needed. On the other hand, brake fluid is cheap (especially compared to major brake system work), and it doesn't cost much even if you change it too often. By the way, brake fluid will damage point, so be careful not to spill it. Also, don't step on the brake pedal when the reservoir is empty as you will introduce air into the brake lines and then you will have to bleed the system. Best regards, Andy Hall -In 9 years and 70,000 km of running, my van has occasionally had sticking brakes due to the following... 1. Sticking wheel cylinder pistons due to corrosion and gunk build-up. Solution: Remove pistons from the cylinder, clean everything out with methyl alcohol and light cylinder honing if necessary. Replace rubber cups if necessary. Flush entire system with new brake fluid. WARNING: DO NOT "FLUSH PARTS IN WATER" -- You don't want any water getting into or inside parts. If you have to use water for some cleaning, make sure to thoroughly dry and then flush with alcohol afterwards to remove any water residue. 2. Rear wheel sticking due to seizing of the emergency brake lever mechanism that connects between the end of the cable and inside the brake drum. Solution: Remove the mechanism and work it back and forth until the joint is loose. Heat and some banging may be necessary but don't bend it :) You can try lubing with some Never-Seiz but it's hard to get into the joint.

Check for local clutch and brake relining shops. (I did have my clutch done that way.) A bigger problem might be wheel cylinders should you need them. I think that the Subaru 360 Driver's Club that I mentioned before has some leads for them. Mike ------------------Curious, but I've had problems with seizing brakes, most often the front left. To get going again, let some juice out of the brake with a 10mm wrench. I rebuilt and honed the cylinders true, and installed new brake return springs. I found some at a parts house that I think were more like the orginals springs than what mine had on it. Still, I had the front left drag on my for a time or two a couple of months ago. Problem has never occurred for me in the summer, so I let it slide when the weather is most suited to doing under the car repairs.... A friend of mine suggested that I must have moisture in the lines. It also occurred to me that I have a defect in my fluid bottle, and perhaps a tiny plastic chip found it's way down into the master cylinder, making the valve stick... who knows? I like my van and though the brakes are kind of weak the vehicle does a good enough job for what I need, and has been very low maintainance for the year and half I've had it. SOmeone else was looking on the net here for a wheel cylinder...dont know but the 360 club newsletters are full of replacement workarounds. OFten someone will get their cylinders resleeved with brass or stainless, then they'll last forever.

North Texas Electric Auto Association <[email protected]> William Glickman Re: Suspension substitution [email protected]

Hi Jerry, Yes, I did change the coil over shocks in my 79 ElectraVan. I used adjustable racing coil over shocks from Carrera. They were the closest when compressed and extended to those that were on the Van. I used coils with 155 pound per inch compression on each front wheel and coils with 125 pounds per inch compression on each rear wheel. I compressed each front coil about 2.25 inches out of a possible 3 inches and each rear coil about 2 inches out of a possible 3 inches after installation. The ride is a little stiff, but body height is correct and the front of Van dips nicely on a panic stop. It was either use Carrera or have new torsion bars made to order and then try to find other inexpensive coil over shocks that I had not found. I tried to readjust the front torsion bar, but was unable to keep the body from being too high. Too high caused the wheels to scrub and make noise on turns. I have the Carrera part numbers in a notebook if someone needs them, but they were about $ 125 per shock. Each shock included a coil spring, adjusting tube, collar, and nut. This price was after a substantial discount because I put their signs on my ElectraVan for the 1996 American Tour de Sol from New York City to Washington, DC. I removed the right front brake drum and found no evidence of a sticking wheel cylinder, weak springs, or broken springs. The drums seem to move in and out with the movement of the brake pedal. It is hard to understand unless maybe the rubber brake hose has deteriorated enough to let fluid get by on the way to the brake drum and not return as fast for some reason. The front brakes are self adjusting, factory set at 0.012 clearance. I may try bleeding both fronts again to see if there is any air in the lines. Later, Bill >On the sticky brake question....

I suppose something that might make my wheels just warm in a half mile might make them hot in 5. WHen my brakes stick, they get smoking in 2-3 miles, and when I come to a stop, I can't even push it. ALso waiting at a light it won't roll at all. Unless you just have a warped drum ( and it gets a little rub on every rev) I would suspect the wheel bearings.

Hi David and all, Last year I picked up a little "One Man Brake Bleeder Kit" at an auto parts store for about $5. Get one, they are the bee's knees. All it is is a plastic bottle with a magnet to hold it above the bleeder screw level, some clear plastic hose, and a couple of plastic tips to fit into the bleeder screws. It makes brake bleeding painless and clean, no more fluid all over the floor. In the past I have used the two man method, the hose and bottle method, and even a preasure bleeder. The little kit is by far the best. It also works for master cylinders. Also one other tip. When bleeding brakes, put a piece of wood on the floor under the brake pedal to keep it from going all the way down. This will keep the master cylinder piston from bottoming out in the normally unused area at the end of the stroke. This is where corrosion, rust, and dirt collect, and pushing into it can ruin the piston seal and the master cylinder.

Using the wood block will mean more strokes to reach the "no bubbles" stage, but would you rather replace the master cylinder? Thanks, Mike Chancey [email protected] / [email protected] See My Electric Car at: http://www.geocities.com/RainForest/Vines/5565/ MAEAA chapter page at: http://www.geocities.com/MotorCity/Downs/4214/-http://solstice.crest.org/discussion/ev/199805/msg00200.html ---------------============================ If the brakes are in good condition, correctly adjusted and the brake pedal goes to the floor when the vehicle isn�t moving and there is no fluid loss I�d be looking real hard at the brake master cylinder as the cause. ============================= By the way.. I would suggest you replace the cylinder and shoes, at least, on the other side as well at the front.. It is not a good idea to have unbalanced components between two wheels on the same axle. ---------------------------When it seems impossible to get all the air out, one trick is to hook up the bleed tube, fill the reservoir, then just pump the pedal like crazy about 20 times. Uses up a lot of fluid, but sometimes does the trick. Brian ========================== I sure like the vacuum pump adapters for bleeding some time the brake light switches have air trapped in them making it almost impossable to get all the air out have fun hank ========================== Things are getting desperate. I have been out there in the brake fluid for 3 weeks now and getting nowhere. I bought brake bleeders for every hole on the MC (just bear with me for a sec) and put them in. Every hole including the switches has a bleeder. I then had my wife hold pressure on the pedal and I bled out every one of the MC holes. This resulted in a rock hard pedal. MC should be good, right?? I then hooked up just the left front line and bled the line. Pedal goes to the floor. I replaced the wheel cylinder on that side just to be sure, then bled it again. Pedal still to the floor. This is getting ridiculous. I have never had so much trouble out of brakes before in my life!! This time it is just with the left front line hooked up and still nothing

I hope someone can help. www.openroad.ca/volkswebbin/viewtopic.php ============================= I remember when I had the same problem on my '71 super, after weeks and weeks of messing with it I finally took it to A break shop and had them put the air bleeder on it, still with no luck. Finally one afternoon when I was down there pumping the break peddle with my hand(because my foot was so tired) I stumbled onto a leak in the line under the carpet. It had simply rusted through, and with the way the fluid was seeping down the frame I assumed the fluid everywere was just part of my mess from a month or so of bleeding breaks. Just something to think about. good luck. steven ================================ Well I pulled up the carpet and checked out the brake line that runs inside the car and everything looks fine. I connected all of the liines and bled the brakes very thoroughly. Now my brakes work great!! At halfway to the floor on the pedal:( Just FYI but I tried a hand vacuum bleeder pump system and it kept sucking air in around the threads on the bleeders. I don't know what else to do. The pedal goes very firm and the brakes work great but they don't start working until halfway to the floor on the pedal. About 3-5 inches of pedal travel before any braking begins. =============================== Dave: You can tell if the MC pushrod is adjusted correctly by the following: get down in there by the pedal cluster and very carefully and without a lot of force, depress the brake pedal by hand (fingertips!) You should feel the push rod just contact (close your eyes and "feel") the MC piston with only a very little free throw. The actual dimension/specification is something on the order of about 1 mm which translates to probably a half inch or less at the brake pedal pad. There is a pedal stop plate down there under and in front of where the pedal cluster is positioned. It is a small "L" shaped plate held in place with a bolt. The plate needs to be positioned so that the faces of the pads on the brake and clutch pedals are essentially vertical (perpendicular to the floor). To me, your problem still sounds like something wrong in the second MC. I think that you mentioned Brazilian or Mexican? I once had a Brazilian unit installed and was never happy with its performance. I swapped it out for a German unit and all the issues went away. Of course the cost for a German unit is probably twice the cost of a Brazilian or Mexican unit, but after all of your trials, probably worth the cost. Good luck. Clancy ============================== O.K. I bled everything VERY well. I got some air out of the left side bleeder but other than that not much air. I adjusted all of the shoes up and noticed that every time I would push on the brakes after adjusting them they would loosen up. So I would retighten them and hit the brakes, they would loosen, then I would retighten, etc.

I readjusted them and took the car for a very short (and very cautious) drive and the pedal went almost to the floor again. When I pulled back in and checked, all of the brakes had loosened up again. =============================== Dave: Another thought... check to see if the adjusters are installed correctly. By this, I mean check out the "slope" in the slot of the end of the adjuster that the brake shoes fit into. This slot slants to one end and the shoes need to be fitted correctly (i.e. it may be necessary to rotate the adjuster 180 degrees to get the shoe to set properly in the adjuster). This could affect the ability to get a proper adjustment of the brakes. Also check to see if the "stop plates" are functional to keep the adjuster stars from turning freely. If they are loose or missing the barkes will "back off" in their adjustment....ust a couple of more things to check. Good luck. Clancy =============================== That's an excellent point Clancy. When I replaced the front shoes and drums I removed everything including the backing plate and cleaned it all. I actually sandblasted and painted the backing plates. I just don't feel like a job is done well unless the parts are clean. I didn't know that there is a certain direction for the slots. It is a definite possibility that I put them back together wrong. So they should slant to the outside? Yesterday I went out to the garage and put clear hoses on each of the rear brake bleeders, then ran each of these into a brake fluid container. I opened both of the bleeders and had my wife slowly push the brakes. I didn't get any fluid movement until the pedal was halfway to the floor. I didn't get any air, but no fluid either until halfway to the floor. To me this would indicate that the MC is just not doing it's job. My local VW guy has a German MC and yes, it is pricey, but it may be well worth it to avoid all of this mess again. Unfortunately it will be the 3rd MC in 3 weeks.One was a rebuilt unit from Autozone, the other a Brazilian, and the 3rd will most likely be the German one. ================================= Checking your adjuster installation is free (if not easy). What are the chances that the two other MCs you bought just happened to be bad? Maybe I'm wrong about this, but I think it's something other than the MC, and based on the adjustment problems you're reporting, I'd start there. 2005-02-02 09:10:17 Quote Clancy Member From: Colorado Springs, CO Registered: 2004-03-27 Posts: 285 Dave: Off the top of my head... I can't remember exactly which way the "slant" goes....but it is pretty obvious once you are staring at them. The shoe base should sit evenly in the slot... try it and you will see it easier than I can

explain it in words. If you're not sure, rotate the slot 180 degrees and take a look. It should be apparent. Good luck. Clancy 2005-02-02 16:29:22 Quote Dave Guest

Here's a quick update. I checked out the adjusters and found that I only had 1 installed incorrectly. Lucky me. So I went ahead and pulled the brazilian MC and replaced it with a new German unit. Now the brakes go about halfway to the floor but with some foot action (pumping) they do come up to about an inch of pedal travel. This indicates some air/adjustment procedures that still need to be done. With everything I have had to do to the brakes in the last few weeks it doesn't suprise me at all. At least with the last round of work to the brakes they are showing an improvement. It really gets annoying when you put in all the time and effort and things just keep getting worse. I'll put the vac bleeder on them (I bled them once already) and see what happens then go back and adjust everything again. On a small sidenote, I found that while using the Vac bleeder before I kept getting air out of all of the bleeders. A LOT of air. But I found out that it was actually air that was being pulled in from around the threads of the bleeders. I put some Teflon tape on the bleeder threads and this seemed to cure that problem. Thanks again, Dave ============================= Hi Dave, You are singing the same EXACT song I was singing two summers ago. I replaced EVERYTHING eventually--and went through tons of fluid while trying to bleed the system. I found the same thing with the vac bleeder. went through bleeders like they were candy.

tons of air, but no pressure.

I

Once I did the teflon tape trick, It worked immediately. I then did the traditional way using an assistant on the pedal. (the vac worked as a quick bleed, but I don't know how complete they are) I also found that some bleeders you get from parts stores are shorter/standard heads with the metric threads. I will only buy the correct lonter bleeders.

congrats on the fix! venture.

UPDATE:PROBLEM SOLVED!!!!!!!!!!!!!!!!!!!!!!!!!!!! I finally found a local VW guy. It took a lot of research and asking around and then once I contacted him he said he was retired and didn't fool with VW's anymore. But he said he would see if he could help me out. I went over to his place and there where probably 15 or 20 VW's sitting around his house. (Retired...right!). Bottom line here is that he took the front drums off and flipped the shoes over and put everything back together, adjusted the brakes and sent me on my merry little way. I had the shoes on backwards, hence the adjusters were backwards. Live and learn I guess. Thanks again for all of the help. Dave =============================== Dave: Congratulations! Were the return springs on upside down as well? This is where a good manual with an exploded diagram or a digital camera for "before" pictures is invaluable. Clancy ================================ ================================ RAY: I can always count on my brother for thinking outside the box. What he bought was a new tire, and when they installed the tire on the car, they didn't balance it correctly, or didn't balance it, perhaps, at all. And as the car is going down the road and the thing is shaking, it is setting up a sympathetic vibration in the disc rotor, which is moving the caliper piston away from the disc, so that when you step on the brake that first time, the pedal will travel almost to the floor. We've seen this happen with cars whose wheel bearings are loose. ================================ A defective master cylinder. If the bore in the master cylinder is pitted or the rubber seals have decreased in size then some fluid will bypass the seals under pressure giving a lower pressure to the wheels and a softer spongier brake pedal. To test for this condition remove the brake lines from the master cylinder and plug the outlets (obtain outlet plugs from a local auto parts store). When you apply the brake pedal it should be high and firm. If it is spongy or slowly goes

down then either the bore of the master cylinder is pitted or the rubber seals are bad. Loose front or rear wheel bearings. If the wheel bearings are loose they will allow the rotor to wobble during use instead of running true. This will cause the pistons in the brake calipers to be pushed back further into the caliper than they were meant to. The result is that the pedal must be pushed further to the floor before the brakes come on. Air in the system. This is obvious but sometimes all the air has not been removed after bleeding. One reason is the incorrect orientation of the bleeder screws in the wheel cylinders. If the screw is not at the highest point on the cylinder chamber then a pocket of air will always remain. Check the screw orientation. Master cylinder piston diameter too small. If the diameter of your master cylinder piston is smaller than required by wheel system volume requirements then you will experience a long pedal travel. Determine what the original master cylunder bore diameter was and replace the master if too small. Remember with an old vehicle the master could have been incorrectly replaced by a previous owner. Wrong master cylinder When you add disc brakes to the rear you must use a true 4 wheel disc master cylinder. The pressure and volume requirements to the rear are much greater than that required by drums, disc brakes require more pressure and volume. A four wheel disc master will have a longer stroke and will provide more pressure to the rear disc brakes. Air in rear calipers Rear calipers are very hard to bleed properly. Sometimes they can be bled only when removed from the car.Try taking them off, place a block of wood between the pads and bleed while tapping and orienting the bleeder screw up. Rear caliper problem If you are using Cadillac ElDorado rear calipers there are some important things you should know. One of the biggest advantages of a disc brake system is the fool proof self adjuster. Not so with this rear GM system. The rear calipers adjust off the parking brake. The parking brake is incorporated into the caliper. You must set the parking brake every time you park the car.The rear caliper pitons utilize a one way clutch inside the caliper piston. When the parking brake is applied the clutch senses when there is .030" or more clearence between the friction material and the rotor on the inboard side. When there is more than .030" the clutch turns inside the piston adjusting it out keeping the rear brakes adjusted. If you do not set your parking brake every time you will start to lose brake pedal (low and spongy) and the adjuster mechanism will not work any longer. Also: never use rebuilt calipers on the rear because the rebuilders use the old pistons and the pistons were the reason the caliper failed in the first place.

I had 18 Douglas (made by Trojan) EV137 (equivalent to T125s) in the van

and had a 40+ mile range down to about 80 % and max of 55 miles down to almost nothing left. You must have some of the brakes sticking or even possibly need to repack or replace the wheel bearings. Also check wheel alignment. I also asked Rob for the cost of another set of five 12 inch wheels for my van. Menlo Park III, Glastonbury Bill ------------------Hi Robb. I do not have the time to make more wheels. It took me two years to do mine! Here is what I did. I looked at several different 12 inch wheels. I decided on 12 inch spoked trailer wheels. I chose there because they are an assembled wheel that I could easily take apart. The spoked hub is welded to the rim with four welds about two inches each. ( see the wheel at www.northrentool.com item #12242 ) I ground off the welds and removed the center hub. I took a 12 inch rim and an original wheel to a machine shop and had disks made to fit. 3/16 mild steel. Next I took all the 12 inch wheels ,disks and the Bus to a fabricator to have the holes drilled and disks welded in. Then paint. Last I got new wheel nuts. I got flange nuts to increase the holding area and minimize the flexing. I have over 500 miles on them and they work fine. One last thing, I filled the tires with dry nitrogen as opposed to compressed air to make the tires last longer. Hope this helps. I highly recommend it.

Ken, I haven't tried this myself, but I understand that about any brake shoe can be relined. I assume that you still have the shoes. Check for local clutch and brake relining shops. (I did have my clutch done that way.) A bigger problem might be wheel cylinders should you need them. I think that the Subaru 360 Driver's Club that I mentioned before has some leads for them.

It's a

must so they can get the arcing right along with clearances. Check your yellow pages. Do the swap NOW to DOT 5 fluid. The one thing is to get the cylinders really polished. They have to be super shiney to keep the DOT 5 fluid from seeping out. I used finer and ever finer polishing compound on a rag-and-stick setup until those cylinders I had looked like mirrors. No more water/corrozion problems ever again

My 1979 Jet Industries ElectraVan 600 gets between 3.5 miles and 4 miles per kilowatt hour of battery storage. It has 8 ply steel belted 145R10 radial tires with a "C" load and 65 psi max pressure ratings. It suffers from a bad reverse gear that either jumps out of gear or has some bad teeth. I have not taken the transaxle transmission apart to find out and will not until there is either hope of a reasonable quick solution or a complete failure. How many miles per kilowatt hour does your ElectraVan perform ? Does your reverse gear suffer the same problem and what is your solution ?? I am also looking for a spare rear drum because the integral spline was slightly damaged after I failed to tighten the castle nut to 116 FT-LBs per shop manual.

--------------------------------------From: "Michael A. Radtke" <[email protected]> Subject: Re: Disc brakes upgrade? Comments: To: EV600-L -- Jet ElectraVan 600 Owners List <[email protected]> Jim, You are certainly correct in calling them underpowered brakes. However, I have had no reliability problems with mine. As far as I can see all the components are original and seem to be OK after 20 years. When I first drove the van, I decided that I needed to deal with the brakes. I did an inspection and adjustment and found all 4 wheels and the master cylinder fine. So I decided to live with the brakes for a while. I have driven about 4,000 miles now and have gotten quite used to the pedal pressure needed to stop. I have had a great number of emergencies and I have done just fine in all of them. Meanwhile, I've investigated solutions to reducing the pedal pressure. I've talked to a number of local brake folks. It surprised me, but the most frequent suggestion was to add a vacuum booster to the master cylinder. However, that looks like a mechanical impossibility to me. I was able to find out that linings with higher coefficients of friction were available. This seems like a good approach since the even though these linings may be more prone to fading, our ElectraVans are unlikely to see conditions where that is

important. One major risk in changing to these linings is that the higher friction could cause the brakes to lock up prematurely when stopping because the existing mechanics of the brakes are probably designed to amplify the brake shoe pressure on the drum when stopping in the forward direction. In other words, the higher friction linings cause the brakes to lock up no matter how lightly they are applied. The consensus seemed to be that the only way to know if higher friction linings significantly reduced pedal pressure without locking up was to try them. This information comes from folks who do less common brakes for things like fork lifts and trucks. Auto brake shops were clueless and brake lining manufacturers didn't want to talk at all. In summary, my plan is to put my van up on blocks and take all the shoes to a truck or industrial type brake shop. I will ask them to reline the shoes with "racing" lining. I plan to start this experiment in the next month or so and I will report back to the list what happens. Of course, if anyone has any clues to help me, I'd most welcome the advice. Thanks, Mike ------->Any thoughts? > >Jim the oem brakes work ok IF everything is just right. I looked into a retrofit to disc brakes and thought it would be too expensive.

When I look at the front of my van, I see what appears to be way, way too much positive camber. The tires lean in so much that the outside edges have tread worn off, while the inside edges have little wear. I took a look at the coilover shocks in front, they appear to be about the right size, and all but about 1 1/2" of the shaft/spring is compressed. The manual just says that "camber doesn't need to be adjusted." Dave Muse Hey Dave, Make sure your toe is correctly adjusted. I was looking in the manual and saw the caster spec is 15 degrees 25'. This is a LOT of caster! most cars are 5 degrees or less. This means any deviation in toe, in or out ,will have your tires riding on either the inside or outside edges. I work on BMW professionally and see this regularly. BMW uses alot of caster on their cars as well, (about 9 degrees). Good for road hugging - bad for tire life. I hope this helps.

Rob, In the process of replacing my tires, I aligned the front end and set the ride height (posture). I found the car quite low and after I set the new height, it looks like the rear has excessive camber. However, the height is in spec now. (I found the 145R10's 1/2 inch lower than the 500X10's, so I reduced the target posture heights by 1/2). I expect that the rear camber is supposed to be that way since I don't think that its adjustable. Is the camber causing tire wear?

Another possible way to balance: On a car with front drums, back off the brake

adjustment on one front side and use that corner of the car as your "balancer". Spin the wheel, mark the bottom when it comes to rest. Give it a best of three spins. Bottom will be your heavier side, weight goes opposite. Keep working up till you have no definite heavy side. Readjust brake. If a tire won't take air because the bead doesn't "seat" on the rim, put a rope around the outside of the tread, twist it tight with your tire iron, then air up. This well expand the bead enough to seat it. --------------------------------------------------------------From: Subject: Comments: To: In-Reply-To: Content-Type:

Hello Bill, I am at work. My manual is at home. My memory is poor. Thus, I don't have a lot of good numbers for you, but here goes: >How far out were the rear wheels ? Toe in is measured in distance. Since I was shooting for zero, I didn't attempt to make my jig give numbers for comparison to the specification. My measurements were about 15 inches in front of and 15 inches behind the axle. At that point of measurement, there was about 3/4 inch toe in. >How did you adjust the rear suspension ? I assume that you mean how did I set the rear toe in. There is an arm on each side of the car that goes from a rear wheel forward on a diagonal toward the center of the car. Just in front of the torsion bar housing these arms terminate with a rubber donut joint to a bracket. Each bracket, in turn, is bolted to the frame with a pair of bolts. Between the bracket and the frame there are shims that look something like the letter E. The bracket mounting bolts can be loosened and the E shaped shims inserted or removed. Just don't take the bolts all the way out. There are large forces at work. The book says the the shims come in 3 sizes and to match the left and right stacks. I think 0.4, 0.6, and 1.2 mm. I found my car had 4 1.2 mm shims on each side. I guessed and removed 3 from both. On driving the car between measurements, I now get 0 + 1/32 to 0 2/32 inch on my personal scale. >How much did you reduce amps at say 35 mph by doing the wheel alignment ? That's a tough question. You know from my other posts that I am uncomfortable with my current measurements. Not only might they be wrong, but they might be unstable. My wild guess is that I am about 40 amperes less at 35 mph than before the alignment. That may be wishful thinking though. >What does your alignment jig look like ? Time for ascii art: a /__ / e / / c \ / / O / / \ / __/ \ / / \ / b \ / O / \ d / / / / / / / f 1) I bent this up out of heavy wire with soldered joints. There is no load on the jig when in use so it is OK for it to be delicate. 2) The short segments at "a" and "b" that rest against the rim must be parallel. This is easily set by resting the jig on a flat surface. The jig can be checked while in use by sliding it to the left and right while in use to be sure that the pointers don't change position. 3) There should be a single point of contact at "d." I rounded this wire end to a ball. 4) Wire ends "e" and "f" should be sharpened since they are pointers. 5) The "c-d" "a-b" wire junction should be at axle height. 6) The short wire segments at "a" and "b" should be about 10 inches apart so they rest on the rim and can be moved sideways enough to prove that they are not resting on the tire. 7) I made my wire "e-f" about 30 inches long. The jig is used by leaning it up against the rim with wire "c-d" vertical and the wire segments at "a" and "b" leaning on the rim, not the tire. When everything is in equilibrium, the pointers at "e" and "f" should just clear the pavement. The pointers should be bouncing about a bit if everything is OK. The position of each pointer may be marked on a piece of tape stuck to the

pavement. The jig is then carefully moved to the other side of the car and the measurement repeated. Errors in the jig geometry will cancel except for lack of parallelism of the short segments at "a" and "b" and any damage that might be inflicted on the jig between the first and second measurements. The distance between the marks may then be used to compute the toe in. I found that the measurements were repeatable to better than 1/32 inch if the car was not disturbed. The front readings were far less stable between drives than the rear, but that is to be expected. Mike --------------------------------Mike my Bus is also 102 volts. I think all this discussion about alignment, bearings, tires etc in regard to range is missing the point. Our vans are about the same. On mine at 40 mph I am using about 190 amps and can go about 45 miles to 80%DOD. You are only using 180 amps at 40 mph and can only go 20 miles. I think you have bad batteries and that they were bad when you got them. BTW high battery temperature improves range but shortens battery life. Rob At 07:31 AM 10/6/03 -0700, you wrote: >Rob, > >My van is mostly original.

102 volts.

-----------------========================== Leave the rear alone, assuming you can even adjust it. Often there is a lot of negative camber and a bit of toe in. The front can usually be adjusted a lot. If you leave the caster alone (assuming that is adjustable, and it may not be) then 0 camber and 0 toe should roll well. A slight toe out is dynamically unstable but the torque caused by tire patch thrust about the lower control arm elastomer bushings should go a bit toe in, resulting in 0 toe. Might be twitchy on the brakes that way as you get more toe out. This is as much a feel thing as anything, espcailly in ruts on the excuses you guys have for road surfaces out West with very friable asphalt with coarse stone. Seth

Subject: Re: 12 inch wheels Comments: To: [email protected] Content-Type: text/plain Hi Mike, I think they stopped making the EV137s and renamed them EV125s. Did you change both inner and outer wheel bearings ? My right front tire get hot and I suspect the inner wheel bearings, but have not had time to investigate. The right rear tire exploded one day several years ago when the vehicle came to a stop in front of my house, after being towed, because the hardened steel splined axle was grinding away at the mating splined iron hub in the wheel and there was no more additional cooling from the wind as the van was no longer being towed. I bought a replacement wheel and the splined steel axle was not damaged. I also happened to have a fifth Avon 145RC10 steel belted radial as a spare tire, so all I need is a new spare whenever I finally get the Van back on the road, but I might invest in a new set of Falkens if it will improve range or load capacity and certainly get a new wheel alignment after checking the inner and outer wheel bearings on all four wheels.

Hi, I purchased the 1980 Electravan that was on Ebay back in May. It's in good condition overall and has been fun to drive so far. The biggest challenge right now is to inspect/repair/replace the brakes and possibly the wheel bearings and/or other parts.

The right front wheel is heating up most. Today the outer face of the wheel was scorching hot to the touch after less then 1 mile travel. The left rear wheel is the coolest running of the 4 and was not even warm after this distance. What is generating the heat and how much heat is normal? Is it just the application of the brakes or would faulty wheel bearings be another cause

======================================= RE: Cracked Rim (he uses 55psi Avons) Hello Bill, Nice to hear from you. To answer your questions: - Not overloaded, but with the batteries it is always heavily loaded. - No corrosion at all on the rims. I live in Phoenix. - The crack formed at one of the clamp bolts, not at a lug. And, the lugs have always been hand tightened and can be removed by hand using the original short wrench. - I didn't hit anything. However, I have more information for you. First, I have had rim clamp bolts break. In the last 4 years, I have had about 4 of them break while driving. I know when it happens because the outside half of the bolt is captive in the wheel cover and makes a lot of noise when it rattles around. Until Monday, only original bolts broke, never replacement ones. Monday, it was one of the replacements. So, here is what happened. Just as I got to work the bolt broke. I chose to drive the car home (10 miles) after work since previous experience indicated there was no problem in doing that. I did keep my

maximum speed below 35 mph. About 9 miles into the trip home, I sensed the tire going flat. However, it lasted long enough to make it home with air to spare. I still hadn't made any connection between the broken bolt and the flat. Not until I was breaking the bead did I spot the cracks in the rim. Between the cracks and the missing bolt, the rim had separated enough to allow the inner tube to squirt into the gap with the expected results. However, I am still confused about the cracking. This is what I found: The major crack is a semi-circle concentric with the bolt hole. It almost looks like a washer. As might be expected, the part that didn't crack is toward the center of the wheel. There are a few radial cracks leading from the main crack going in the direction of the tire. These cracks allowed the rim to bend enough to damage the tube. Only one of the rim pieces appears cracked. So, the crack does not imply that the bolt was loose. As luck would have it, I was able to recover both halves of the bolt. From the position of the nut, there is no indication that the bolt was loose. The sides of the bolt don't appear worn. It has a rather clean break as if it were broken by stretching. If the cracks were relieving the stress already, why was the first sign of trouble the bolt breaking? It leaves me rather uneasy about the condition of all of the rims. I'll post again when I get some information about replacements. I have two leads so far. I have been trying to reach Jim Turner, the father-in-law of Nolan Scheid (thanks) who posted earlier. I also ran across a Subaru racing chick, who works in a Subaru parts department, likes Subaru 360s, and offers to get OEM parts for them from Japan. Thanks, Mike [email protected] For my first set of tires, I imported some Avon radials from the UK. These tires rode rougher and had a heavier steering effort than the original bias ply tires but stuck to the road like glue. They cost nearly $100 each after shipping. They didn't last long. I went back to bias ply for the second set of tires. I found some Chinese Cheng Shin for less than 1/2 the price of the Avons and they were in stock in Denver. I prefer them to the radials mostly because they start to slip gradually under stress instead of suddenly breaking loose like the radials. In summary, I am happy with 10 inch tires. The braking is another issue. I'm pretty sure that the stock gas powered van has adequate braking. The ElectraVan does not. But the issue is not about the braking ability, but rather about the pedal pressure. Over the years, I have had a few emergencies where I have locked the brakes. But then, I am used to the high pedal pressure. A new driver of the van has serious safety issues. What the ElectraVan needs, are not bigger brake drums, but rather, a power assist. Unfortunately, there is no engine vacuum and no space around the master cylinder.

Thanks, Mike -----------------------------Hello, After buying 2, I now know that Subaru 360 van rims are wrong for my ElectraVan. I am once again in the market for a couple of ElectraVan rims. suggestions would be appreciated.

Any

Thanks, Mike Lawrence, Been there done that. In talking to them, I was convinced that the 360 van rims would fit. They have both ElectraVan and Sambar 600 owners in the club. So, I bought a couple of wheels for a 360 van. It turns out that they were 1/2 inch narrower. I could live with that. However, they were also made of thinner steel. Since my genuine wheel failed due to fatigue, I couldn't live with that. So, I am looking again.
