O Ring
Genuine Mtd part
By: Mtd
Part Number: 791-181751

This is a genuine replacement O-ring, which is a standard part on a number of engines. This O-ring is specifically designed as a replacement for the one found in the carburetor on select lawn and garden engines. The O-ring is designed to create a seal in the carburetor to ensure optimal performance and prevent leaks. It is also designed to help create the right amount of pressure. Over time, O-rings can become corroded, worn, or damaged due to their exposure to pressure and high heat. If they become broken or damaged, they can result in poor engine performance or even total engine failure. This genuine OEM O-ring is manufactured by RYOBI and compatible with a number of tillers, trimmers, and blowers from this brand. It is also designed for use with select models from Bolens, Yard Man, MTD, and Troy-Bilt. There are more than 150 models that can use this specific O-ring. It is made of durable materials and sold as an individual unit. Keep in mind that because O-rings have multiple applications and engines may have more than one type, it is important to double-check the location and application of the part to ensure the right one is being used.

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.
