Few parts fulfill as many roles on lawn mowers and other landscaping power tools than the cover screw. This screw serves to attach metal housing parts, assemblies, and shrouds to one another on equipment such as power vacuums, snow blowers, edgers, tillers, hedge trimmers, lawn tractors, leaf blowers, grass trimmers and cultivators. As these are extremely durable metal screws, they seldom fail under ordinary use. It should be noted, however, that they are most often used at connection and pressure points. Stresses at these junctions sometime loosen screws, causing them to be lost or occasionally resulting in stripped threads. It's also occasionally the case that these screws are lost during repair or routine maintenance of yard equipment because of their small size. Users should make sure to consult their owner's manuals for replacement steps and any special instructions. Because of their small size and the ease of losing them during repair work or maintenance, it's recommended to keep a supply of appropriately sized screws on hand. Most importantly, when replacing a part make sure to use a genuine OEM replacement part. They are manufactured according to the specs of the original parts and are perfect replicas.

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.

This is a genuine replacement screw designed for use in select MTD engines on lawn and garden equipment. Specifically, this is an anti-rotation screw, which is used to stop the drive shaft housing from turning inside of the main housing assembly. This screw is a small part that is subject to constant vibrations, pressure, and high temperatures. It can sometimes become worn or damaged as a result or even break off entirely, which would mean that the inner housing would no longer be held in place accordingly. If this screw is damaged or lost, it needs to be replaced with a genuine OEM replacement as soon as possible. This MTD anti-rotation screw is manufactured with high-quality materials and designed for use in select trimmers from MTD, RYOBI, Yard-Man, Troy-Bilt, Murray, Cub Cadet, Yard Machines, and Bolens. This replacement will require a screwdriver. Simply remove the damaged screw, if it is not already missing, from the clutch cover assembly, and then install the new screw.

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.

O-ring gasket creates a seal to prevent fluid and gas leaks in tillers and lawn equipment. Replace when cracked, brittle, or leaking. Verify fit.

These O rings are replacement parts intended for use in a number of gasoline-powered lawn trimmers. The O rings serve as gaskets and are placed at the entry and exit points in the carburetors where gasoline and air are mixed and the expansion powers the trimmer. Though constructed of durable material, periodically the flow of the air/fuel mix or the rush of expanding air will cause damage to occur to the O rings so they become less resilient and the carburetor functions less efficiently. In these cases, users often decide to replace not just the element of the carburetor but the O rings as well. Users may notice problems with the carburetor when they cannot get an adequate adjustment, allowing the trimmer to function smoothly. They may also have trouble getting the trimmers to start at all or run without smoking. To replace the O rings, remove the air filter cover and carburetor. Once the carburetor has been cleaned, and the gasket and filter replaced, add a fresh mix of 40:1 fuel. The trimmer should start immediately. These OEM certified O rings are compatible with Bolens, Troy-Bilt, Yard Machines, and Craftsmen trimmers.

A carburetor gasket is a thin rubber material that provides a seal between two parts. Its primary purpose is to prevent fuel and air leaks. This gasket is installed between the air cleaner and the carburetor. Over time, it can crack and tear due to heat and fuel exposure. When this happens, the carburetor may produce the wrong combustible mixture for the engine. In return, the engine may experience rough idling and flooding. A carburetor gasket replacement is necessary. MTD makes this carburetor gasket replacement. It is manufactured to fit string trimmer, leaf blower and tiller made by MTD, Bolens, Troy-Bilt, and Craftsman. This brand-new carburetor gasket is sold individually. A fully assembled carburetor and O-ring are sold separately.
