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 is a small engine spark plug positioned in the engine cylinder head. It supplies the spark that will ignite the air-fuel mixture to enable an engine to produce power. This particular spark plug is designed with superior corrosion resistance and dependable performance. Small but mighty, this component allows for increased conductivity and heat control. If the spark plug is damaged or in poor condition, many problems may arise in equipment, including sudden stop while running, overheating, and excessive gas consumption. Replace the spark plug by disconnecting the spark plug wire first, then use a socket driver or wrench to remove the spark plug. Install the new spark plug by turning it by hand initially to avoid cross-threading. If it doesn't twist anymore, use a deep socket wrench or socket driver to tighten the plug until snug. The spark plug can also be used to tune up outdoor power equipment or improve a small engine. This part is recommended to be replaced once per season.

Cylinder head gaskets provide a seal between the engine block and the head that caps the cylinders. They ensure that the cylinders, oil, and cooling channels are isolated from one another and contain the pressure in the engine. If there is a problem with a gasket, it could result in overheating, white smoke from the exhaust, and leaks.The cylinder head gasket undergoes a lot of stress when the engine is running. Over time, the gasket can start to wear down, crack, and break. Owners will want to replace the gasket to ensure the machine is running properly and efficiently. Replacing the cylinder head gasket can be a large job even when working on a small engine.This cylinder head gasket is used in engines from a range of manufacturers including MTD, Craftsman, Columbia, Yard Machines, Cub Cadet, and Troy-Bilt.
