Good To Know

Q: How many main bearings does a crankshaft typically use? A: Most crankshaft assemblies use several main bearings to support the crank along its length, so check your service manual for the exact count and position needed. Q: Should main bearings be replaced as a set? A: Replacing bearings as a set during a rebuild is common practice so wear stays 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.
