I recently purchased a standard size main bearing set from a large vendor, checking the clearances I am finding this new set will provide a clearance at the high limit per factory specs. My crank is spot on, but the main bearing ID appears too large. I can easily fit a .004 feeler between the crank and new bearing ID. Just for fun, I tried an old (used)main bearing and found it to have a smaller ID (by about .0015) than a new one. Am I missing something?
Thanks |

Yes the old bearing remains crushed. Yes you can do a before and after. If the after is not good after crush, you may have to find another set. Silverline is the only one that is steel backed. NOS German ones are rare these days.
