Good To Know

Q: How do I know this wrist pin bearing fits my engine? A: Match the OEM number 420832440 and confirm your machine runs the 650 series engine. Checking your parts diagram before ordering avoids surprises.

Q: Should I replace other top end parts at the same time? A: Wrist pin bearings are commonly replaced alongside pistons, rings, and wrist pins during a rebuild. Inspecting the rod small end for wear while it is apart is a smart step.

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