Lower Piston Ring 6686133

This lower piston ring creates a tight seal between the cylinder and crankcase, preventing fuel leaks in your outdoor power equipment. It is located between the piston and the cylinder, and has dimensions of approximately 1 inch by 1 inch. If you notice visible damage on the ring, it may fail to seal properly, resulting in fuel leaks, fuel system issues, or engine failure. To remove a broken lower piston ring, refer to your user guide for disassembly instructions and locate the ring. Remove any components blocking access to the crankcase and cylinder, such as the cylinder head. Use pliers and a ring compressor to carefully compress and spread the lower piston ring, releasing tension, before sliding the ring up and off the piston. This authentic OEM part is sold individually and sourced directly from the original equipment manufacturer.
