Parts for Briggs & Stratton 44N877-0005-G1: Engine Gasket Sets Parts

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.

Many small yard and garden machine engines will feature a crankcase, which is a metal case that covers the crankshaft of the engine. This crankshaft mounts to the case and features the valve and camshaft mechanisms as well as connecting to a belt or chain drive for the engine. It is connected by bolts and features an upper and lower portion joined together with a gasket. The lower portion holds lubricants to help keep the engine running cool. The crankcase gasket creates a seal that ensures no oil or air leaks, but the gasket can deteriorate over time. This replacement gasket is designed to work with small engines made by Toro and Briggs & Stratton. It features the gasket and specialized bolts to ensure the tightest seal. This is an OEM part and will require appropriately sized wrenches as well as disassembling the crankcase. Bolts require use of a torque wrench and will be tightened to 300 inch pounds. This assembly ships individually with gasket and bolts.

When the fuel in a small, gasoline-powered engine moves up the fuel line, it must be mixed perfectly with air and together burn in just the right mixture and amount in order for engines to function properly. Because too much gas might be coming into the carburetor or because there might be a need for more gasoline than can readily move up the fuel line, the carburetor has a small device called the float bowl. The float bowl has a ready supply of gasoline for use as needed by the carburetor. To keep the gasoline in check while all this is happening, a device called the float bowl gasket keeps all the elements separate. With use and age, sometimes these gaskets crack or grow brittle and must be replaced. This causes air to leak into the mix and the engine will not operate smoothly. Replace this gasket with a genuine OEM replacement part like this one, manufactured to be exactly like the factory original that is being replaced. This part is compatible with engines sold by Toro, Simplicity, MTD, Briggs & Stratton, and Cub Cadet. Part sold 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.
