Tips for maximizing cam bearing performance in . - Mahle Aftermarket

Clearances must be measured at installation. Honing the ID's of cam bearings to increase clearance is not recommended because hone grit may become embedded in bearing surfaces which will cause shaft wear. Bearing ID's may be reamed, but the most practical means is to adjust camshaft journal diameters by grinding.

Engine Crankshaft: Crank Grinding - .010”/.010” Myth

Mar 27, 2017 . In order to make a 514 big block Ford, the rod journals are offset ground down to 2.20” which means that they are 0.280” smaller than the original diameter of the rod pin. If all of these cranks can be ground down by .050” to .280” and used in a diesel truck or a high-performance engine, it only makes sense.
