This replacement part is a piston, and it is intended for use in different types of lawn equipment. This is a genuine replacement part made by MTD. This piston is commonly found in lawn mowers and is an important part in the user process. Pistons help transfer the combustion power of the engine to other working parts of the machine. A new piston might be needed if the overall performance of the engine is lacking compared to previous uses. If the lawn mower is not able to build enough power to accelerate, the piston might be faulty. It is also common for the engine to use an excessive amount of oil or put out white or gray exhaust smoke. All of these indicators might mean that the piston should be replaced. This part is a genuine OEM replacement part. This piston is sold individually and can be used in lawn mowers manufactured by MTD.

This is a genuine OEM gear governor assembly sourced from the manufacturer for use in many small engines in lawn and garden equipment. The gear governor assembly engages the drive shaft on small engines and maintains the speed of the engine based on presets from the manufacturer. The governor adjusts the throttle as the load increases or decreases. If the governor is not working properly, the throttle would have to be adjusted manually when the load increases and decreases.If the engine runs too slow or too fast, or if it surges, the governor may need to be adjusted. With the engine in idle, move the governor lever manually to open up the throttle. If the governor is working properly, it should push the arm back to its idle position. Fine-tune the governor using the screw on the bottom of the arm of the governor. Loosen this screw so that the throttle is wide open. Locate the clip that is connected to the governor shaft and turn clockwise. This sets the governor.The gear assembly is sold individually. It is designed for an array of small engines. This governor assembly is compatible with various models MTD, Cub Cadet, and Troy-Bilt engines.
