Install Tips: This chain tensioner installs much like an OEM Honda/Acura unit, with the exception of a few details. The tips shown below and on the following pages are not meant as a complete install guide, but do illustrate several critical steps. For additional information, please consult a Honda or Acura Shop Manual. It’s recommended that the timing chain tensioner be installed while the motor is OUT OF the vehicle. Installing it while the motor is installed in a vehicle is possible, but difficult. These install tips are written assuming the motor is out of a vehicle. Please read the entire install guide before beginning your installation to get a good grasp of what lies ahead of you. If you feel as if you cannot complete this installation please consult a professional mechanic. IF THIS PRODUCT IS INSTALLED IMPROPERLLY YOU RISK BLOWING UP YOUR ENGINE, so take your time read the install guide and call us if you have questions. Step 1: Once the timing chain cover has been removed, reinstall the crank pulley retaining bolt using a 19mm socket or wrench. This will be used to turn the motor over manually. If you are replacing a tensioner that failed and caused the chain to become slack or skip teeth, it's important to inspect the chain guides. If the guides have become chipped, cracked, gouged or damaged in any way, they should be replaced with new or undamaged guides, to avoid any timing chain related problems.

Step 2: Using a 19mm socket and ratchet or breaker bar, turn the crank clockwise. Notice as you turn the crank that the left chain guide moves from side to side. This will be less noticeable if stock cams are being used. Turn the crank until the left chain guide is as close to the right chain guide as possible.

Step 3: Wrap a zip around the two chain guides where they are closest to one another and pull it closed. Tighten it as much as possible. This will hold the chain in place while you are installing the new tensioner. Note that if the timing chain slips or comes off the guides during this process, you will need to redo the timing as per the OEM Honda or Helms manuals.

Step 4: Using a 10mm socket or wrench, remove the 2 bolts (indicated) that hold the OEM tensioner onto the motor. Once these are removed, the OEM tensioner can be taken off of the motor.

Step 5a: Using the 2 supplied bolts, affix the new chain tensioner to the motor (see arrows marked 1). . Step 5b: Remove the thumbscrew that retains the tensioner’s hydraulic piston (arrow 2). Note: Do not remove this thumbscrew before the tensioner is installed on the motor. Doing so can potentially damage the tensioner irreparably.

Step 6: The sides of the piston on K-Series timing chain tensioners have two flattened portions near the tip. These flats are meant to fit snugly into a mating portion of the left chain guide. Make sure that the front of the piston is seated in the chain guide as shown in figure 6 (see arrow).

Step 7: Remove the upper retaining bolt and slightly loosen the lower retaining bolt of the tensioner. Tilt the tensioner up slightly (as shown) to allow the piston to ratchet out one click. Do not allow the piston to lose contact with the chain guide. Reorient the tensioner and reinstall the bolts. Using a torque wrench, tighten the bolts to 8.5-9 ft-lbs of torque

NOTE: If your tensioner has "DO NOT PRELOAD" engraved on the front of it, skip this step. Tensioners with this marking are designed so that preloading is not neccesary.

Step 8: The zip tie holding the chain tight can now be removed, allowing the new chain tensioner to keep pressure on the chain.

Step 9: Before putting the timing chain cover, crank pulley and all other ancillaries back on the motor, use a 19mm socket and ratchet or breaker bar to turn the crank clockwise a few times. This will allow the tensioner to cycle and advance the ratchet mechanism if necessary. Important Note: When initially installed, the tensioner will have only assembly oil on it that is used to inhibit corrosion. It’s important to prime the tensioner with motor oil before running your motor. To do this, unplug your injector clips and turn the motor over several times as if you were starting the car. After you complete this step and you have ensured that some oil pressure has Developed, go ahead and attach the injector clips back onto the injectors and crank the engine. Let the engine sit and idle for 10 minutes; during this time listen for any loud slapping or clanking of the timing chain against the guides. If you hear any noise that does not sound healthy or correct stop what you are doing and consult a professional mechanic or call/email Hybrid Racing. Failure to do so could cause irreversible damage to your engine.
