Good To Know

Q: How do I know if my wrist pin bearing needs replacing? A: Rough running, knocking from the top end, or visible play between the wrist pin and connecting rod during a tear down all point to replacement. Since it is a wear item, most builders swap it any time the piston comes out.

Q: Does this bearing come as a single unit? A: Yes, this listing is for one wrist pin bearing. Confirm the quantity you need based on the number of cylinders you are servicing.

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