Crankshaft Endplay Shims - .38mm

These shims set the endplay of the crankshaft. It is very important that you get this right. The endplay should be between .003" and .005". Too loose and you will beat out the rear main bearing, too tight and the flywheel will try to grab the rear main bearing and spin it. If you are going to use old shims, make sure they are not cupped. Flex them one by one to see if they pop; if they do, they're cupped. Note: The way to set the endplay is to leave out the flywheel seal and o-ring. Find three .010" shims; install the three shims and bolt on the flywheel. Torque the flywheel to 250 ft. lb. Using a dial indicator mounted on the flywheel with the needle against the case, push the flywheel back and forth to get a reading. If you have too little or too much then take the flywheel off and figure out what you need to add or subtract to come up with the correct endplay. You may need to take out a shim(s) and add a thicker one(s). You must have a total of three shims; no more no less. After you get the correct thickness, install the seal and o-ring.
