String Trimmer Transmission, Brake & Clutch

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. This OEM clutch replacement is designed for use with various cultivators, edgers, and trimmers. It can be used on machines from MTD, RYOBI, Troy-Bilt, Bolens, Yard-Man, Cub Cadet, Murray, and Husky. This assembly includes the clutch, clutch drum, washer, and left-hand threaded screw. Always disengage the spark plug and allow the engine to cool completely before beginning repairs.

String keeps spinning at idle or engine overheats? A worn clutch assembly causes engagement issues. This centrifugal clutch repair restores normal operation.

This OEM sprocket assembly contains a sprocket, which is a circular gear with teeth that engage with the links on a chain to move the chain forward.A new sprocket assembly will be needed if the part is broken in any way or if the sprocket teeth are worn off. If it's not immediately obvious to the eye, a test can be performed to determine if a new sprocket assembly is needed. Simply move the chain and if at any point the chain becomes stuck, this means a new sprocket assembly is needed. Remember to wear gloves when operating or performing care and maintenance on any outdoor power equipment machines.This is a genuine MTD part sourced directly from the manufacturer and is sold individually. The sprocket assembly is compatible with trimmers manufactured by either Troy-Bilt or Cub Cadet.

This clutch assembly engages and disengages the drive system on a tiller, allowing the tines to spin when the clutch lever is activated. It transfers power from the engine to the tine shaft.

This gear set kit includes the gears needed for the edger attachment on a string trimmer.
