Posting this for my brother
BBC, assembling bottom end after a little mishap. Freshly polished crank. Rod bearings are at .0019. Acceptable limits I've read are .0020-.0025. Should he have the crank polished more? Hes already using the oversized bearings(+.0001).
Are Mains ok in the .0025-.0030 range? Im not sure where he is at there, but Im sure he wants a confirmation...
Thanks for the advice!
