Parts for Briggs & Stratton 49M877-0110-E1: Engine / Valve Gasket Set, Carburetor Overhaul Kit 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.

The oil seal plays an important role in protecting the oil as it flows into the crankshaft and engine block. It creates a strong seal and ensures that the oil can flow effectively into the engine for proper operation. Over time, rubber seals degrade and wear out, so their replacement will be a part of routine maintenance. If there are oil leaks around the crankshaft or engine, this seal may be the culprit. Replacing the oil seal will ensure proper oil pressure and avoid oil leaks that could lead to more serious damage. When installing this replacement part, it is important to use a rubber mallet or large socket to tap the part into place. This is a genuine Briggs & Stratton part that is a replacement for various compatible small engines. It can fit select engines on Toro, Husqvarna, and Briggs & Stratton equipment. This oil seal is sold individually and compatible with a variety of engines. This OEM replacement is made of durable rubber and sold individually.

This O-ring seal is used in all sorts of lawn and garden equipment as a seal for the oil dipstick. It helps seal the system from debris and dirt that could otherwise reach the oil and end up in the motor. Over time, an O-ring will start to shrink, which can result in air and oil leaks and a poorly performing engine. If the O-ring has pits, blisters, or pocks on the surface, it will also need to be replaced.If an O-ring seal is worn, damaged, or clogged, it should be cleaned or replaced before the equipment that houses it is used again. A flat head screwdriver can be used to remove the damaged O-ring. Once the old one has been removed, a new one can be placed into the same position before using the tool.This O-ring seal is designed for lawnmowers, snowblowers, tillers, wood chippers, pressure washers, generators, and leaf blowers. It is compatible with equipment from Simplicity, Briggs & Stratton, MTD, Craftsman, Snapper, Toro, Lawn-Boy, and Cub Cadet. The seal is a genuine OEM replacement part directly sourced from the manufacturer. It comes with a single seal.

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.

This is the rocker cover gasket, which seals the cylinder head on small engines so that the engine doesn’t develop leaks. Periodically, a gasket may deteriorate with heavy use. To maintain good engine performance, the rocker cover gasket needs to be replaced with an OEM certified replacement. This type of gasket is most often found on lawn tractors. Replacing the original gasket with the new one is a simple and straightforward process. There are four bolts holding the valve cover in place. Simply remove them and the old gasket, which will likely have to be scraped to get it completely off the cylinder head. Place the new gasket exactly over the metal frame of the cylinder head—it should fit perfectly. Hold it in place with a small amount of RTV, a silicon sealer that is impermeable to oil and gasoline. Replace and tighten the four valve cover bolts. This part is made by Genuine Midwest Engine. This part is used in Briggs & Stratton engines and also used by Toro and Vanguard. This is an OEM part. It's also sold individually.
