Wrist Pin Bearing for Sea-Doo

This wrist pin bearing is a connecting-rod small-end bearing that supports the wrist pin inside the piston, and it carries the OEM cross-reference 290832320.

Overview

This wrist pin bearing for Sea-Doo is the small-end bearing that fits between the connecting rod and the piston pin on a two-stroke engine. It allows the wrist pin to pivot smoothly under load so the piston tracks straight in the bore without excess play.

Specs At A Glance

Good To Know

Q: How do I know if my wrist pin bearing needs replacing? A: A rattling or ticking from the top end, loss of compression, or a scored piston usually points to a worn wrist pin bearing. These are typically replaced as part of a top-end rebuild.

Q: Is this an original Sea-Doo part? A: This is an aftermarket wrist pin bearing that cross-references OEM number 290832320. It is not an original Sea-Doo product.

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