This oil seal is a genuine OEM replacement part designed for use on a wide variety of small gas-powered appliance engines. Although small, an oil seal is an important part of the oil cylinder assembly as it prevents oil from leaking into other parts of the engine. If oil begins to leak into the engine, it can corrode other parts or even pose a fire hazard. Therefore, it's important that the oil cylinder is tightly sealed to prevent any damage to the engine. Seals can wear out over time, especially if exposed to heat. Heat will cause the seal to shrink, effectively unsealing the oil cylinder. Before making this repair, be sure to drain the oil cylinder of any oil and be prepared for an involved replacement process. This part is compatible with Toro, Murray, and Briggs & Stratton appliances and is sourced from the original manufacturer. It ship individually of other hardware.

This replacement oil drain plug is a genuine OEM part for a lawn tractor or generator engine. The oil drain plug connects to the base of the oil tank and allows the appliance owner to drain used oil and replace it with new, clean oil.

This genuine OEM replacement part is a spark plug terminal for a wide variety of small combustion engines. In a combustion engine, the spark plug generates a small electrical charge that creates enough power to start up the ignition and engage combustion. The plug connects to the ignition through the terminal. Spark plugs generate and then pass a small electrical current through to the ignition. Usually, the main issue with spark plugs is that this current hyper-extends and ends up frying the spark plug. However, if the terminal is damaged, the charge will not pass into the ignitor, and the engine will not turn. If the spark plug can carry a charge but the engine still won't turn, it's likely the terminal that needs replacing. This is an easy repair because the terminal should just snap on and off. If stuck, a pair of needle-nose pliers should make it easier. This high-quality replacement part is compatible with engines from Murray, Toro, Lawn Boy, and Briggs & Stratton. It is sourced from the original manufacturer and ships individually.

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 replacement exhaust gasket is a certified genuine OEM part for a lawn tractor engine. This gasket helps to seal off the exhaust from the carburetor. For an engine to run, it must first mix fuel with air to prepare the fuel for combustion. By sealing off the exhaust, this gasket allows for fresh air to enter into the carburetor from outside the engine rather than from the exhaust. Gaskets often degrade over time due to the stress of pressure and heat. If the exhaust gasket breaks its seal, it can affect the engine's overall performance. Be on the lookout for an especially noisy engine that doesn't provide as much power and is less fuel efficient. There may also be a noticeable burning smell coming from the engine. To replace the exhaust gasket, use a socket wrench and wrench set to remove the air filter and blower housings, then remove the exhaust manifold and switch out the gasket. This replacement exhaust gasket is compatible with engines made by Toro, Briggs & Stratton, Murray, Snapper, and Simplicity. It comes sourced directly from its original manufacturer and does not include any additional hardware.
