Good To Know

Q: What does a piston ring filer do? A: It grinds the ends of piston rings so the end gap meets the clearance called for in the engine specs. This manual filer uses a 120 grit wheel to remove material gradually for a square finish.

Q: Is the grinding wheel replaceable? A: The kit ships with a 120 grit grinding wheel, and replacement wheels of the same style and size can be fitted when the original wears down. Always check the wheel condition before starting a ring filing job.

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