This is a replacement rocker arm adjuster that is specifically designed for use in select lawn mower engines. The rocker arm adjuster attaches to the rocker arm, which is responsible for opening and closing the valves on the engine responsible for injecting fuel and air. By doing this, it impacts the horsepower and performance of the engine. Over time, rocker arm adjusters can become lost or damaged. If they are not functional or are missing, the rocker arm will not be able to open and close the valves appropriately and the engine may not function at all. This genuine OEM rocker arm adjuster is manufactured to exact standards for Briggs & Stratton engines and is designed to offer an exact replacement for the part that came with the machine originally. This part can also be used as a replacement on select models from Toro and Lawn Boy, with over 150 machines that can use this rocker arm adjuster in total. The part is made of durable materials and sold as an individual unit. No additional hardware or parts are included. Never perform repairs on a hot engine and always wear gloves for hand safety.

This genuine OEM replacement intake manifold gasket for a small gas-powered lawn appliance motor acts as a seal between two engine components, like any other gasket. However, the intake manifold gasket is one of the most necessary gaskets because it is responsible for sealing the engine vacuum and coolant. Intake manifold gaskets can be damaged because of their location in the engine. If the engine has been running hot for a while, the metal can expand and crush the gasket, causing it to fail. If this happens, the engine will begin overheating, as coolant can no longer reach the areas where it is needed. Replacing an intake manifold gasket will mean removing the air filter and its housing, the oil drain tube, blower housing, breather tube, and carburetor. Making this repair requires a set of socket wrenches and screwdrivers. This part is compatible with a wide range of mowers, chippers, and blowers from Briggs & Stratton, Toro, Cub Cadet, MTD, Simplicity, and Lawn Boy. It is sourced from the original manufacturer and ships individually.

This is an O-ring seal that can be used in many types of engines for lawn and garden equipment. It is responsible for sealing the connection between the cylinder head assembly and the intake manifold. The sealing process prevents dirt and debris from moving throughout the equipment and getting into the motor. As time passes, the O-ring seal can shrink, causing oil or air leaks and decreasing engine performance.When the O-ring is damaged, clogged, worn, or broken, it will need to be cleaned or replaced before using the lawn equipment again. The damaged or broken O-ring seal can be removed using a flat head screwdriver. After it has been removed, the replacement component can be installed in the same place. Make sure that the O-ring seal is properly seated to avoid additional leaks. Reassemble the parts before using the tool. This is a genuine OEM replacement part that is sourced directly from the manufacturer. It is sold individually. It is used in lawnmowers, lawn tractors, snowblowers, and wood chippers manufactured by Simplicity, MTD, Lawn-Boy, Cub Cadet, Toro, and Briggs & Stratton.
