Frequently Asked Questions

Q: Is this piston pin lock compatible with my Raptor engine?

A: Yes, this part is designed specifically for Raptor engines. Please note that this SKU (555035) has been superseded by part number 691588, which is the current standard for this application.

Q: Why is it important to replace the piston pin lock during a rebuild?

A: Piston pin locks are critical for engine integrity. Reusing old clips can lead to metal fatigue, potentially causing the clip to fail and allowing the pin to slip, which can cause catastrophic damage to your cylinder wall and piston.

Q: Do I need special tools to install this piston pin lock?

A: While it is designed for simple installation, we recommend using a pair of needle-nose pliers or a dedicated snap-ring tool to ensure the lock is seated firmly in the groove without bending or deforming the clip.

Q: How do I know if the lock is installed correctly?

A: After installation, ensure the lock is fully seated in the groove around the entire circumference. A properly seated lock will not rotate easily and will prevent any lateral movement of the piston pin.
