Good To Know

Q: How do I know when a main bearing needs replacing? A: Knocking from the bottom end, low oil pressure, or metal debris in the oil are the usual signs. Tear down and inspect the journals and bearing shells before ordering.

Q: Should main bearings be replaced as a set? A: Replacing all main bearings together is standard practice during a rebuild so wear stays even. Check the crankshaft journals for scoring at the same time.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
