Parts for Yard-Man 41ADY42C901: Engine Assembly Parts

Few parts fulfill as many roles on lawn mowers and other landscaping power tools than the cover screw. This screw serves to attach metal housing parts, assemblies, and shrouds to one another on equipment such as power vacuums, snow blowers, edgers, tillers, hedge trimmers, lawn tractors, leaf blowers, grass trimmers and cultivators. As these are extremely durable metal screws, they seldom fail under ordinary use. It should be noted, however, that they are most often used at connection and pressure points. Stresses at these junctions sometime loosen screws, causing them to be lost or occasionally resulting in stripped threads. It's also occasionally the case that these screws are lost during repair or routine maintenance of yard equipment because of their small size. Users should make sure to consult their owner's manuals for replacement steps and any special instructions. Because of their small size and the ease of losing them during repair work or maintenance, it's recommended to keep a supply of appropriately sized screws on hand. Most importantly, when replacing a part make sure to use a genuine OEM replacement part. They are manufactured according to the specs of the original parts and are perfect replicas.

The O-ring is designed to create a seal in the carburetor to ensure optimal performance and prevent leaks. It is also designed to help create the right amount of pressure.

This is a genuine air box assembly designed to be used with select trimmer models. The air box assembly is responsible for holding and housing the air filter that helps remove debris and dust from the air as it enters the engine. The base assembly connects to the machine, while the air filter element goes inside the base and the plastic cover snaps on top to protect everything.

This is a genuine replacement air filter designed for use with select models of lawn and garden trimmers. The air filter fits into a special assembly located near or on the carburetor and is designed to filter the air coming into the carburetor from the outside. The filter will remove debris and particles before allowing the air to pass into the engine, which means it will naturally become clogged with regular use over time. Air filters are typically a routine maintenance part and some owners will keep an extra filter on hand just in case they need it. When the filter is clogged, it will need to be replaced, whether it is time for maintenance or not. This genuine OEM air filter is manufactured by MTD and compatible with a number of trimmers from the brand, as well as select models from Yard Man, Cub Cadet, and Yard Machines. The air filter is made of durable foam material and designed to fit over the plastic air cleaner assembly, which is underneath the air cleaner cover. No tools are required to replace this part since the air cleaner cover snaps onto the base. This is sold as an individual unit and does not include the air filter assembly.

Clutch won't engage or burning smell from your tiller? This clutch assembly connects engine power to the tines. Moderate DIY repair for tillers.

This is the clutch drum that houses the clutch that engages the power tools on more than 50 gasoline-powered lawn and landscape devices. The clutch sits inside this housing, which enables it to rotate. When the RPMs of the engine reach a certain point, the clutch expands and causes the drive shaft of the tool to engage. Among the different kinds of equipment that use this clutch housing are cultivators, edgers, and grass trimmers. The clutch, and therefore the clutch drum, receive a great deal of wear for several reasons: the vibration of the engine, the rapid up and down change of engine revolutions, and resistance met by the tools that are transferred back to the clutch and housing. Signs that the clutch is failing include a slow response to increased engine RPMs and an inability for the power tool to engage the drive shaft. In these cases, the clutch and housing should be replaced in order for the equipment to operate properly again. When choosing a clutch housing, it is important to select one that, like this one, is a genuine OEM certified part. This housing is compatible with Craftsman, Troy-Bilt, MTD, Bolens, Yard-Man, and Ryobi equipment.
