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. It is designed for use in lawnmowers, lawn tractors, and other small engines manufactured by Briggs and Stratton, Toro, Lawn-Boy, Simplicity, MTD, and others.

This connecting rod is a genuine Midwest Engine replacement part for appliances operated by small engines, including lawn tractors, lawn mowers, snowblowers, leaf blowers, vacuums, tillers, and generators. The function of a connecting rod in an engine is to link and hold together the piston and the crankshaft.A connecting rod might have to be replaced if it suffers damage over time; damage to a connecting rod can have disastrous implications for an engine if repeatedly used in a state of disrepair. Symptoms of a compromised connecting rod could include a knocking sound from the engine when it is running, unusually low oil pressure, reduced fuel economy, and consistently low oil levels. The most productive method to determine the efficacy of a connecting rod is a simple visual assessment; however, this will require a full breakdown of the engine and a careful examination of the piston, the crankshaft, the bearings, and the connecting rod itself. Remember to always wear gloves when handling, repairing, and operating outdoor equipment. This connecting rod is compatible with the following brands: Briggs & Stratton, Toro, Cub Cadet, and Simplicity.

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.

The exhaust valve is a component found on an assortment of tools and lawn and garden equipment. It is attached to the valve seat. The exhaust valve vents the cylinder. With increasing pressure during combustion and compression, a fuel-air mixture is pushed around the exhaust valve's outsides and between the valve seat and valve. With regular use, the exhaust valve will wear out. Burning through oil, high smoke levels, and poor engine performance indicate problems with the exhaust valve.If the exhaust valve is worn or damaged, it must be replaced. Pliers are helpful when repairing or replacing the exhaust valve. Wear gloves for safety, and make sure the device has had ample time to cool.This exhaust valve is an authentic OEM replacement part sourced directly from the manufacturer. It is sold as an individual unit. The exhaust valve is made of high-quality, durable metal materials. It is compatible with Briggs and Stratton and Toro brand equipment. Some of the machines it can be installed in include lawn mowers, lawn tractors, vacuums, generators, blowers, and other engines.
