Specs At A Glance

Good To Know

Q: How do I know if my wrist pin bearing needs replacing? A: Excessive noise from the top end, reduced compression, or visible wear during a teardown are common signs. Always inspect the bearing any time the piston is removed.

Q: Can I reuse my old wrist pin bearing during a rebuild? A: Reusing a wrist pin bearing is not recommended since these components wear gradually and are difficult to inspect accurately. Replacing it during any top-end service is the safest approach.

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