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 part is a breather gasket. This specific breather gasket is manufactured for use with small engines. The breather gasket forms a seal between the breather and the cylinder.

It's recommended to replace the breather gasket any time the breather itself is serviced to ensure that a proper seal is maintained. This part is a genuine Midwest Engine part and is an OEM part sourced directly from the manufacturer and it is sold individually. This specific breather gasket is compatible with engines, lawnmowers, and generators that are manufactured by Midwest Engine, Briggs and Stratton, Toro, and Lawn Boy.

If any of these are occurring, the flywheel key should be replaced to prevent complete engine failure.A flywheel puller tool is required for this repair. Make sure the engine is cool before working on the flywheel. Wear safety gear, including gloves and eye protection. Disconnect the spark plug and remove the blower housing. Remove the flywheel mounting nut and set it aside. Take the recoil starter cup off the mower. Use the flywheel puller to remove the flywheel and access the flywheel key.

This screw is a genuine Midwest Engine replacement part for small engine appliances, including lawn tractors, lawn mowers, snowblowers, leaf blowers, vacuums, and tillers. The purpose of a screw is to tightly link materials together through rotation that pierces into the material. A screw might have to be replaced in the event that it is lost or misplaced, a common occurrence due to its size. A screw might also be replaced if it deteriorates over time, through erosion, cracking, or piercing, thereby reducing its efficacy in holding materials together. This kind of damage can be attributed to general overuse, to age, or simply to long-term exposure. If a screw is subject to any of this kind of damage, it is best to replace it immediately, as the materials held together by the screw must continue to be held together. Remember to always wear gloves when handling, repairing, and operating outdoor equipment. This screw is compatible with the following brands: Briggs & Stratton, Toro, Cub Cadet, and Lawn Boy.

A flange screw has a range of applications depending on how and where it is used.

Owners should replace the screws as needed to ensure the proper operation of their machine. This is a genuine OEM replacement flange screw that is 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.
