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.
