Replacement Trimmer Belt
Genuine Mtd part
By: Mtd
Part Number: 954-0625A

This is a wheeled string trimmer belt compatible with many brands. The belt's purpose is to drive the unit, transferring power from the engine to the cutting head. Over time, belts are subject to wear and tear, heat, and humidity. This can make the belt brittle and eventually it will snap. In other instances, belts will stretch after being used for long periods and need to be replaced. Replacing the belt is a simple process. Start with the engine off and the spark plug disconnected. Remove the screw holding the chassis cover in place and then the screws holding the debris shield. With the debris shield out of the way, the belt should be clearly visible. Remove the engine pulley, but make sure to note the pulley's position for replacement. Install the new belt and reassemble the trimmer. This part is a genuine OEM part sourced directly from the manufacturer and sold individually. This belt is compatible with Craftsman, Bolens, Remington, Ryobi, and Yard-Man brands.

Clutch Assembly
Genuine Mtd part
By: Mtd
Part Number: 753-05860

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.

Gearbox Assembly
Genuine Mtd part
By: Mtd
Part Number: 753-06882

This is a genuine replacement for the line trimmer gearbox on select outdoor power trimmers. The gearbox is the housing that holds the gears responsible for turning the line reel. When the line reel turns, the string cuts grass and weeds. This part is made of durable metal, but it is also exposed to the elements and a lot of constant vibration, so it can become damaged over time and will need to be replaced. If the trimmer head stops spinning or there is a sudden grinding noise, it could indicate that this part needs replaced. It's important to use an OEM replacement for best results. This unit is sold as a complete assembly and includes the mounting hardware, three screws, head assembly, and the cap. A hex screwdriver, socket or wrench set, and Phillips screwdriver will be necessary to replace this part. Be sure to allow the unit to cool and wear gloves whenever performing repairs.This genuine OEM line trimmer gearbox is manufactured by MTD and compatible with machines from Craftsman.

Insulator Assembly
Genuine Mtd part
By: Mtd
Part Number: 753-06189

This is an insulator assembly includes the insulator, seals, and hardware. It is designed to create the right spacing between the cylinder and carburetor on many blowers and trimmers made by various manufacturers. The insulator assembly also keeps heat from moving between the other components. Over time, the insulator assembly can become damaged or crack. When this occurs, air can reach the engine and create a condition where the engine can't perform at its best. If this happens, the insulator assembly will need to be replaced. Take off the air filter, drain the fuel, and remove the intake assembly. The insulator can be taken off of the engine before the replacement is added. Use mounting screws to fit the insulator to the other components. Reassemble the other parts to use the tool.This insulator assembly is a genuine OEM replacement part sourced directly from the manufacturer. It is sold as an individual part. This component is made to be used in leaf blowers, tillers, and string trimmers manufactured by Craftsman, Cub Cadet, Troy-Bilt, Murray, Yard Machines, MTD, Bolens, and Yard-Man.
