talking to the guy i bought the motor from the other day, and he asked how many shims i had to put in the flywheel. I said..." shims?". When i bolted and torqued it 80lbs, i didnt see anything about no shims! Engine seemed to turn over by hand, alittle stiff, but turned over none the less. Could i be hurting it running w/ too much tension or something? Im planning on taking the trans back out for some parts replacement, i guess ill mic it then and check, but if its too tight could it toast the motor i guess?

I'm not sure why it is critical that you use 3 shims, but I know that this is the number that is specified for the engine and every engine builder that I know of makes a big deal out of making sure you have 3, not 2.
You definitely need shims because this is how you set the end play for the crankshaft. It should have .004 ( I think - don't trust this number) of end play on a Type IV. If you don't have a dial indicator gauge, I'd load the engine up and take it to your mechanic so he can measure the end play and get you the combination of 3 shims that will give you the proper end play. You DO NOT want to get this wrong as it will lead to massive oil leaks at the flywheel seal and failure of your engine! This post has been edited by ThinAir914: Jun 7 2005, 11:35 AM |
