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.

Fix engine performance issues or loss of compression with this valve spring. Common in lawn mowers, snow throwers, and other outdoor power equipment engines.

Seals the intake valve to prevent oil leaks and maintain proper compression in small engines. Replace if you notice oil consumption or performance loss.

Engine losing power or running rough? A worn cylinder head assembly often causes reduced efficiency. This part covers the cylinder and houses valves.

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. This part works with lawn mowers, snowblowers, tillers, leaf blowers, log splitters, wood chippers, and others with small engines. It is compatible with brands such as Craftsman, Cub Cadet, Troy-Bilt, Murray, Yard Machines, MTD, Huskee, Bolens, Yard-Man, and MasterCut. This is a genuine OEM part directly from the manufacturer and is sold individually.

This is a short block assembly for a small engine, consisting of the engine block, crankshaft, piston, and connecting rod as a pre-assembled unit. It serves as the core mechanical foundation of the engine, providing the compression and power generation needed to operate the equipment. Replace this assembly if the engine has seized, has low or no compression, or shows signs of significant internal damage such as scoring on the cylinder walls.

External gasket kit seals carburetor and engine surfaces on lawn equipment. Replace when you notice fuel leaks or loss of compression. Verify fit with your model.

This complete gasket kit includes the gaskets needed to seal various engine components on outdoor power equipment. The gaskets prevent oil, fuel, and air leaks between mating surfaces such as the cylinder head, crankcase, and carburetor. Replace if you notice oil or fuel leaks, loss of engine compression, rough running, or if gaskets appear cracked, brittle, or damaged during an engine rebuild.
