Frequently Asked Questions
How do I confirm these piston pin locks are correct?
Match the exact wire or spiral-lock design, diameter, groove dimensions, wrist pin, piston family, included quantity, and manufacturer part number.
Can used piston pin locks be reinstalled?
Use new locks unless CP expressly authorizes reuse for the exact design. A distorted, damaged, or incorrectly seated lock can cause major engine damage.
How do I verify a pin lock is fully seated?
Follow the current CP installation method, inspect the entire lock in its groove, verify the opening orientation where specified, and confirm the wrist pin cannot contact or dislodge the lock.
