Good To Know

Q: How do I know if my wrist pin bearing needs replacing? A: Grinding or rattling noises from the top end, a piston with visible play on the pin, or a bearing that turns roughly by hand are all signs it should be swapped.

Q: Does this bearing need to be greased before assembly? A: It should be oiled with the correct two-stroke premix or assembly lubricant during installation so it stays protected during the first startup.

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