This replacement piston ring is a high quality item that is sourced from original equipment manufacturer for use on Craftsman gas powered lawn and garden equipment. A worn or broken piston ring will allow combustion gases to escape the seal and enter the crankcase causing low compression and the loss of power. If compression is reduced significantly, the engine will not be able to run at all. Please note one durable metal piston ring is included per order requiring a wrench set and pliers to complete the repair.

This is a genuine OEM approved replacement part designed for use with Hitachi nailers. The piston is a central component of an engine. It both provides compression within the engine, as well as transfers the energy from combustion to the crankshaft (which creates rotation). This assembly includes the metal piston, ring, two retainers and the pin. Replacing the piston assembly is not the simplest repair, but it is definitely something you can do yourself. You will need a screwdriver to remove the cover and a set of sockets and wrenches for the rest of the repair.
