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. There are more than 150 compatible machines for this breather hose. This high-quality composite rubber hose is sold individually.

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 complete gasket kit that is sold as a genuine OEM replacement for MTD lawn and garden equipment engines. The engine contains various gaskets throughout the components that are responsible for creating a good seal and ensuring the proper flow of air and fuel through the equipment. Over time, these gaskets can become worn, brittle, or warped and should be replaced.It is always best to replace all of the gaskets at the same time with this OEM complete gasket kit. It is manufactured by MTD and designed to work with select engines from Troy-Bilt, MTD, and Cub Cadet. It is a good idea to inspect gaskets while performing other engine repairs or maintenance. This can help identify issues before they become bigger problems and allow for a quick gasket repair instead of a total engine overhaul. The gaskets should be replaced one at a time and the area where they sit should be cleaned to ensure a good seal. Never take all of the gaskets out and try to replace them at once. It can be confusing and it may be difficult to get things back together. This complete gasket kit includes all of the gaskets that are needed for a full engine replacement.

This replacement part is an external gasket kit, and it is intended for use in different types of lawn equipment. This is a genuine replacement part made by MTD.

If there are noises coming from inside the machine it is possible that the parts of the gasket are out of place or could be malfunctioning. Be sure the engine of the appliance is completely powered down and cooled off before replacing the gasket kit as this area can be hot from use.Be sure to reference the specific user manual prior to beginning this repair.
