409Kwsb0d518 Parts

This ring set is a genuine OEM replacement part sourced directly from the manufacturer. It is made explicitly for lawn and garden engines found on Briggs & Stratton machines. These rings are found between the walls of the cylinder and piston. The rings prevent combustion gasses from getting into the crankcase. Over time, the rings can become worn and damaged, causing loss of engine compression, power loss, and even total engine failure. Signs that the rings are bad include white or gray smoke coming from the exhaust, loss of power, excessive oil consumption, and low or no accelerating power. A ring expander, screwdriver, and socket set are necessary to complete this project. Remove the spark plug wire before removing and replacing the ring set to prevent accidentally starting the engine. Drain the fuel into a clean container. Remove the engine. Locate and remove the piston. Open the piston and remove the rings using the ring expander. Install the new rings in the same order the old ones were removed. Reinstall the piston top, and then reinstall all engine parts in the same manner. Install engine and refuel the machine. This ring set is made of durable metal and is sold as an individual part. The ring set is specially made for small engines manufactured by Briggs & Stratton.
