Troy-Bilt Tiller 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.

The gearbox assembly is found in tillers and is where the gears are housed that supply the drive and torque for the unit. The gearbox assembly is designed to provide protection for the gears and the other internal components, which are responsible for transferring energy to increase torque and control speed.

The gearbox assembly is sold as an individual assembly and comes ready to install with the four screws required for installation. Be sure to wear gloves and disconnect the power from the tiller before performing any repairs.
