the lined boxes can be used as input under shims it is possible to put what you got to get in limits. As shims do have only some types of thickness. rim indicator on right hand coupling on mtbm face indicator on right hand coupling face to left hand coupling rim positive means mtbm is high face positive means mtbm is too high [email protected]
