Good To Know

Q: How do I know if my main bearing needs replacing? A: Knocking noises, low oil pressure, or metal debris in the oil often point to a worn crankshaft main bearing during a rebuild.

Q: Should main bearings be replaced as a set? A: It is good practice to replace all crankshaft main bearings together so clearances stay even across the crank.

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