The clutch assembly uses centrifugal force to connect the shafts and create the drive shaft motion that powers the machine. The drive shaft nests inside the other shaft, and over time these parts can wear and become damaged with regular use. Today's parts can even continue to function long past when they should, so it may not be apparent that a clutch assembly needs to be replaced until the entire unit is bad. If the engine is not performing as it should or if the drive shaft seems unstable, it may be time to replace the clutch assembly. This genuine OEM part includes everything needed for the job.

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.
