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.

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.
