This is an MTD rocker arm. The rocker arm works in conjunction with the engine and head. The job of the rocker arm is to push the intake valve open, allowing fuel and air to enter the cylinder. Since the rocker arm is a part of the head gasket system, any damage can cause the engine to run extremely weak. There could also be a noticeable clicking or ticking noise originating from the engine area of the mower. A visual inspection of the rocker arm will confirm any damage. Begin the repair by removing the muffler guard. After removal, move to the valve cover and remove that guard as well. Disconnect the fuel and air lines running to the head. Remove the spark plugs in the valve section. Finally, the rocker arm can be removed using a socket wrench. Repeat these steps in reverse to install the new rocker arm.This product is sourced directly from the manufacturer as a genuine OEM part. The component is available individually, separate from the original machine. This part is compatible with MTD and Cub Cadet brand equipment.

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.
