Specs At A Glance

Good To Know

Q: How many wrist pin bearings does a rebuild normally need? A: Count the cylinders you are servicing and order one wrist pin bearing per piston. Replace them any time the top end is opened for a piston or ring service.

Q: Does this bearing need extra lubrication during assembly? A: Coat the rollers with assembly oil or two-stroke premix before sliding the wrist pin through. Proper pre-lubrication prevents a dry start on first fire-up.

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