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. 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.

Replace this stud if it is stripped, bent, broken, or if the carburetor is loose and causing air leaks or poor engine performance.

This replacement part is a stud, and it is intended for use in different types of lawn equipment. This is a genuine replacement part made by MTD. Studs are typically found in or around the carburetor in many lawn mowers. These studs hold specific parts in place and keep the engine running smoothly and efficiently. A new stud might be needed if the user notices that different parts of the carburetor are loose or even missing. It is possible that the previous studs become stripped or worn down over time due to normal wear and tear. It's possible that the stud can become stuck as well, and the user might need pliers to retrieve and replace it with a new part. This replacement part is sold individually and is a genuine OEM part sourced directly from the manufacturer. Be sure to purchase the correct amount of studs as many machines require more than one for proper operations.

Replace your broken or missing engine dipstick. This essential oil level indicator installs in the engine block to monitor oil levels and prevent damage.

This is an authentic OEM replacement part sourced directly from the manufacturer for use in various small engines. This oil fill tube assembly is part of the oil delivery system. This tube delivers the oil to the oil tank when it is added to the engine. If this tube cracks or deteriorates over time, the oil will not make it to the oil tank or the engine. This could lead to complete engine failure if the leak is not discovered. Oil on the driveway or lawn or smoke coming from under the engine when the lawnmower is running is a sure sign that the tube may need to be replaced.The oil fill tube assembly also houses the dipstick which is used to check the oil level in the mower. If the assembly is leaking, the reading won't be accurate and the lawnmower may be operated without adequate oil which can damage the engine. A screwdriver is needed to replace the oil fill tube. Do not replace this part until the engine has cooled. This oil fill tube assembly is made of black molded plastic and sold as an individual unit. It is designed for use in lawnmowers and other small engines manufactured by Toro, Tecumseh, and Briggs & Stratton.

Plastic primer bulb that draws fuel into the carburetor when pressed. Replace if cracked, broken, or no longer creating proper seal for priming.

The breather hose is designed as a valve or vent that only functions one way. It allows air into the fuel tank but ensures that no air or emissions escape the tank. When this hose is not functioning, emissions and air could be leaking from the tank and cause the engine to perform poorly or not perform at all. The hose could become cracked or damaged, or the ends could lose their seal. Either way, a replacement hose will solve the problem and get the equipment back in order. This genuine OEM replacement breather hose is made by MTD and manufactured to exact specifications. It is compatible with several engines on lawn mowers, snowblowers, and chippers from brands like Troy-Bilt, MTD, Yard-Man, Yard Machines, Bolens, Cub Cadet, and Husky.

It's best to have spare O-ring gaskets on hand to rebuild a carburetor when the need arises. Use this manufacturer-approved replacement part to complete the process. When outdoor power equipment shuts off just after starting or won't start altogether, there may be a problem with the carburetor. It could be a leak that causes compression problems keeping the machine's engine from starting. Gasoline may drip from the float bowl because of an O-ring that won't seal or seat evenly all around, or one that has become brittle over time. This is a genuine OEM part compatible with specific lawnmowers, snowblowers, wood chippers, log splitters, tillers, and other garden maintenance machines from Craftsman, MTD, Cub Cadet, MasterCut, Troy-Bilt, and Yard Machines. It is sold individually.
