Replacing the flywheel key is a part of routine maintenance for many modern engines, so it should be inspected and replaced as needed. This sturdy metal flywheel key is easy to install, but remember to choose the right torque setting when doing the replacement. Always disengage the spark plug and wear gloves when replacing engine parts. This genuine flywheel key is designed to be used in a number of lawn and garden equipment products from MTD, Troy-Bilt, Yard Machines, Cub Cadet, Yard-Man, Husky, and Bolens.

This replacement part is a regulator bracket. It is a genuine replacement part made by MTD. Regulators are found in many appliances and machines that operate similarly to cars. This regular controls the voltage within the lawnmower so that the correct amount of charge is going back into the battery while the engine is still running. A new regulator bracket might be needed if the battery on the appliance is no longer working. This can mean the regulator is not doing its job and providing proper charge to the battery over time. Be sure the engine is powered off and cooled down before attempting to replace this part. It is also recommended that working gloves be used to prevent injury. This part is sold individually and is sourced directly from the manufacturer. This is also an OEM replacement part to ensure long-lasting use.

This is an oil filter designed to fit a variety of small, gasoline-powered motors used primarily on lawn equipment. This genuine OEM replacement filter removes contaminants that otherwise would wear down the internal working parts of the engine. While the filter works very well, it should be replaced annually as a part of regular maintenance. Depending on use, the filter may need to be replaced more often. When replacing the oil filter, the crankcase oil must be drained and safely discarded as well. To remove oil from the gasoline engine, start the engine and let it run for a couple of minutes. This circulates the oil and heats the internal engine parts so oil is better able to drain. Next, remove the drain plug located on the bottom of the oil pan and collect the oil. Remember to dispose of the oil safely where it cannot contaminate streams or aquifers. Once the oil has been removed, remove the old filter and discard it properly. The new filter should only be hand-tightened in place as using a wrench may cause the filter gasket to seal to the engine block. This filter will fit Yard Machine mower engines and MTD equipment.
