Finally assembling the freshly machined 59ab motor with a .010 under 4" stroke crank. Main bearing clearances, (new bearings), measure .0015 but the crank end play is .010. This is a hobby car, like most, seeing limited use. What are my repair options and what can I expect if I don't don't fix to get in the .002-.006 range. This crank was machined previously. The car will have a T5 trans. Thanks.

I have a set of Federal Mogul .010 bearings which I will mic for you, let me know... If you can, speak to your crank grinder- sounds like you can't. Don't know if I'ld run this or not...

This question was answered by JWK a few weeks back. put a .005" shim behind the bearing flang.

To all those who responded. Thank you very much. I now have some real direction. I'll keep you posted. This is my first flathead and have encountered many unusual things ..at least unusual to me . It's always nice to know there is so much knowledge willing to be shared.
