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 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.

This cylinder head gasket is a genuine replacement part for select small engines. The cylinder head gasket is installed between the cylinder head and the engine block. It is responsible for creating a seal for the internal combustion engine to work properly and to help keep the oil and coolant separate as they travel between the cylinder head and the engine block. Gaskets are considered a maintenance part because their exposure to high heat and pressure cause wear, warping, and other damage over time. When a gasket is damaged, the seal is affected. Air could escape or the oil and coolant could mix, which would both produce bad results for the engine. This genuine OEM cylinder head gasket replacement is manufactured to exact standards by Briggs & Stratton. This part is compatible with select engines found in lawn and garden machines manufactured by Briggs & Stratton and Toro. The gasket is sold as an individual part and does not include any hardware or additional components. Be sure to allow the engine to cool and wear gloves when replacing gaskets. It is a good idea to replace gaskets when performing other engine repairs to ensure a proper seal when putting the engine back together.

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.
