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 O-ring is an OEM part sourced directly from the manufacturer, and it is sold individually. The manufacturer of this product is MTD. This O-ring is designed for use with different types of outdoor lawn and garden equipment, including snowblowers and log splitters. It is compatible with products made by the following brands: MTD, Cub Cadet, and Craftsman.The design and purpose of the O-ring is relatively self-explanatory. It is an “O” shaped ring of material which is used as a gasket. It is designed to sit within a groove and be compressed during assembly. The reason for this is to create a perfect seal that blocks the path of liquids or gases from escaping or flowing into regions of the machine where they are not supposed to be.To replace an O-ring, check the air filter cover, remove the carburetor, and clean it thoroughly. Next, replace the O-rings, carburetor gasket, and air filter, followed by the spark plug. Regular maintenance of the carburetor and routine evaluation of the suitability of the O-ring is essential to proper mechanical maintenance.
