This oil seal is a common part engineered to work in engines that power generators, vacuum cleaners, snowblowers, leaf blowers, mowers, and other small engine applications. The seal sits between the crankcase and the crankshaft. It is designed as a barrier to prevent oil leakage and to stop contaminants from leaving the crankcase. When the gasoline engine exhibits diminished power, and especially if it begins to emit oily gray or bluish smoke, there is a good chance the oil seal needs to be replaced. In order to replace the faulty seal, begin by removing the starter housing and taking off the nut that holds the starter wheel to the main shaft. The user will find the old seal on this shaft. Remove it and install the new seal, pushing it into place with the edges of a socket, then tapping it securely into place with a hammer. When choosing a replacement seal, remember to use an OEM genuine replacement part that is guaranteed to match the specs for the original part. This will ensure a quality match and long replacement life. This seal is compatible with Toro, Lawn-Boy, and Briggs & Stratton engines.

This genuine OEM gasket sits between the carburetor and cylinder to create a seal on a wide range of different lawn mower engines. The carburetor is responsible for mixing fuel and air, so it is important that it remains well sealed. The cylinder sits on top of the combustion chamber, and must also be sealed to provide the proper amount of pressure to drive the pistons. Therefore, it's crucial that nothing escapes from the engine where these two parts meet. Gaskets are designed to take a lot of wear and tear, but they can eventually blow after repeated exposure to heat and pressure. When a carburetor and cylinder gasket blows, the engine will not perform as well. Look out for vibrations, backfiring, low output, or an engine that stops shortly after startup. To replace this gasket, use a screwdriver, wrench set, and pliers to gain access to the carburetor's inner workings.
