A valve cover is a small but important piece of hardware designed for use with pieces of outdoor lawn and garden power equipment that have small engines, such as a snow blower or a tiller. It is compatible with products by brands such as MTD, Yard Machines, Troy-Bilt, Yard Man, Cub Cadet, Bolens, and Husky.The valve cover part is crucial because it plays a big role in keeping the engine protected and healthy. The valve cover is a type of casing that can be found on the top of the machine's engine. It covers the valves of the engine, which in turn protects the machinery from the elements and prevents oil leaks. Over time, natural wear and tear with exposure to the elements will occur, leaving evidence on the valve cover in the form of cracks, corrosion, and misalignment of the valve cover. If the valve cover shows signs of wear such as these listed, it can make fluid leak into the engine compartments. If this happens, it is very serious and will ultimately lead to engine failure.The replacement or repair process of the valve cover should be straightforward, but the user replacing the part should always be sure to wear gloves during any assembly, replacement, or installation processes. The user should also refer to the owner's manual of their equipment and any guiding diagrams that clarify the placement location.This valve cover is an original OEM part sourced directly from the manufacturer, MTD. It is sold individually.
