What is the best way to install bearings? Last engine I just cleaned them with solvent and scotchbrite. Installed with plenty of assembly lube. When #1 piston shattered and rod punched a hole in the cylinder wall. Upon teardown some of the bearings had what looked like chatter marks around the bearing. Engine never lost oil pressure before shut down. BIGG C

No need to clean them with solvent or scotch brite. Just blow them off good after you install them before you lay on a thick bead of assembly lube.

Clean them with solvent only, then blow dry w/air. Don't scrub or use a scotchbrite. (xtreme) have you ever seen how dirty, clevite or federal mogul Main brgs are?? Don't know why but the rod brgs are usually pretty clean. And yes the race brgs are the ones iam refering to. Josh K.

The dirt should come off with compressed air, if not, take them back. There is a coating on the Clevite bearings for inital start up that needs not to be disturbed. If anything, dip a soft cloth in solvent and gently wipe the surface, but I'd rather just blow them off
