This valve spring retainer is a genuine OEM replacement part that is designed for use with select snowblowers and snow throwers. The valve spring retainer is responsible for holding the valve spring in place, which then controls the valvetrain. The retainer secures the spring so that it can provide the right amount of pressure to ensure that the system can operate without valve b, which can damage the engine or cause faulty operation. If the valve spring retainer fails or is damaged, which can happen with regular use over time, it will need to be replaced to ensure the spring remains in place during the operation of the machine. The retainer is a metal collar-type piece and although it is durable, it could wear out or break due to several different potential situations. Regardless of the cause, a replacement must be made with an OEM part like this. This genuine part is manufactured to specific OEM standards by MTD, and is compatible with more than 150 units from MTD, Yard Machines, Yard Man, Troy-Bilt, Husky, and Cub Cadet. It is sold individually. Be sure to wear gloves and allow the unit to cool completely before performing any type of repairs.

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.
