Craftsman Chipper Shredder Engine

This piston ring set is specifically designed for use in several types of lawn and garden equipment. The piston rings are the components that maintain the proper fuel compression between the cylinder wall and the piston. These parts are used to fully seal the cylinder, so gas that is generated during ignition doesn't leak out into the opening between the cylinder and piston. If the piston rings have gone bad, the equipment could use up gas much more quickly, have poorer performance than expected, expel white or gray exhaust smoke, or be incapable of accelerating. Piston rings can be damaged through lack of oil, dirt in the cylinder, or stale fuel that creates a build-up. If the piston rings are not working properly, they should be replaced. It's also a good idea to inspect the cylinder for any additional damage.This is a piston ring set that is designed to be used with lawnmowers, snowblowers, and generators manufactured by Briggs & Stratton, Craftsman, Cub Cadet, Toro, Tecumseh, and Simplicity. It is sold as an individual set. This is a genuine OEM replacement part set that is sourced directly from the manufacturer.
