This replacement valve seal is a genuine OEM part for a lawn tractor or mower. The valve stem is a type of valve that transfers oil into the cylinder and then immediately reseals due to the pressure in the chamber. However, if the seal is damaged, it will not close and oil will leak into the cylinder. If this happens, the cylinder head may become overly lubricated and not run well. This seal helps prevent that from happening. It fastens to the intake valve and valve stem keeper. Seals will naturally wear out over time due to stress and exposure to corrosive oxidizing agents in an engine. When this happens, the valve will leak oil. To test if the valve seal is compromised, look for whitish-grey smoke that indicates burning oil and also measure to see how much oil the engine is consuming. If the seal is breached, use a screwdriver and socket wrench set to change out the part. This top of the line replacement valve seal is compatible with Briggs & Stratton, Toro, and Lawn Boy lawn tractors. It is sourced from the original manufacturer and ships individually.

This rocker arm is a genuine Midwest Engine part. A rocker arm is a vital part of an internal combustion engine that controls the intake and exhaust valves in order to direct power from the engine to the wheels, setting the appliance, such as a lawn tractor, wood-chipper, snowblower, or lawn mower in motion. Natural wear and tear from extended use over a long period of time can cause an internal combustion engine to malfunction or fall into disrepair. The longer a rocker arm is in use without replacement, the more likely it is to be subject to damage. This will require a replacement rocker arm. Signs of weakening infrastructure for which the rocker arm might be responsible can include unexplained clicking noises, stalling engines, lit-up check engine lights, and clear visual signs of deterioration on or around the rocker arm itself. Always wear gloves when handling, repairing, and operating outdoor equipment.This rocker arm replacement part works with engines, lawn tractors, wood chippers, snowblowers, and lawn mowers from brands Briggs and Stratton, Toro, Cub Cadet, Lawn Boy, Craftsman, MTD, and Simplicity.
