rod bolts/change bearings?

**john5632** · 07-04-2007, 07:17 AM

I bought some Katech rodbolts,and was wondering if I should change the rod bearings,or if it would mess up the balance and leave the bearings alone.If i do change them,which ones? Ive looked at the clevites in summit,but did not know which ones to get.Does any one have a part number on which clevite bearings to get

the ones i used in my motor are CB-663H. H means hardened race bearings. P is standard factory type bearings. they can take more abuse. the 1, 10, and 20 are the undersize when you have the crank turned, or are trying to close up the gap to meet tolerances.

without measuring the rod inner diameter versus the rod journal on the crank, the CB-663 is standard, no undersizing.

on this page, it explains what H, P, and V means.
