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.

Flange screws have a flange located near the top of the screw, which helps to distribute the connection force over a larger area to reduce potential damage to the machine. It also allows the screws to be used in oversized or irregular holes, and it helps to ensure they stay in place. This flange screw also has a hex top. Screws can last for a long time. However, they may become corroded or worn over time and need to be replaced. They could also become lost and need a replacement. Without all of the screws in the proper places in a machine, it could vibrate too much, which could render it less effective or unsafe to use. The flange screw is a genuine OEM part that can be used with many types of machines including lawn mowers, snowblowers, tillers, pressure washers, leaf blowers, generators, wood chippers, and other small engines. The screws are compatible with Briggs & Stratton, Craftsman, Toro, Cub Cadet, Murray, Lawn-Boy, Snapper, Simplicity, and MTD.

The flywheel key is the component on outdoor equipment that keeps the flywheel connected to the crankshaft. Over time, this key may become damaged or broken, particularly if the engine experiences a forceful stop, like hitting a large stationary object. If the flywheel key breaks, the engine will not start. A slightly damaged flywheel key is noticeable through symptoms like misfiring, backfiring, or having no power. 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. Remove the broken flywheel and replace it with the new flywheel. Reverse the steps to put the mower back together.This flywheel key is made of an aluminum alloy and is sold as an individual part.

This ring set is a genuine OEM replacement part sourced directly from the manufacturer. It is made explicitly for lawn and garden engines found on Briggs & Stratton machines. These rings are found between the walls of the cylinder and piston. The rings prevent combustion gasses from getting into the crankcase. Over time, the rings can become worn and damaged, causing loss of engine compression, power loss, and even total engine failure. Signs that the rings are bad include white or gray smoke coming from the exhaust, loss of power, excessive oil consumption, and low or no accelerating power. A ring expander, screwdriver, and socket set are necessary to complete this project. Remove the spark plug wire before removing and replacing the ring set to prevent accidentally starting the engine. Drain the fuel into a clean container. Remove the engine. Locate and remove the piston. Open the piston and remove the rings using the ring expander. Install the new rings in the same order the old ones were removed. Reinstall the piston top, and then reinstall all engine parts in the same manner. Install engine and refuel the machine. This ring set is made of durable metal and is sold as an individual part. The ring set is specially made for small engines manufactured by Briggs & Stratton.
