Simple Installation Tip:
When installing the 080V02502-0129 piston pin, ensure the small-end bushing of the connecting rod is properly reamed and lubricated. Use a hydraulic press with protective sleeves to avoid damage during insertion. Confirm free float in both piston and bushing after installation — no binding allowed.
