Good To Know

Q: Do I need to hone the cylinder? A: Yes, cross-hatching the cylinder wall is essential to help the new ring seat properly and maintain lubrication.

Q: How do I check the ring gap? A: Place the ring inside the cylinder and use a feeler gauge to verify the end gap meets the manufacturer's specified tolerance.

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