• Releasing the handles allows the ring to settle into the piston groove.

• Groove cleaner includes three cutting discs, with adjustment along a flat bar to suit the piston diameter.

• Three ring compressors hold the rings compressed during piston insertion into the cylinder.

• Carrying case keeps the tools together for storage and transport.

Typical applications
