This is an OEM replacement crankcase gasket for use in select MTD lawn and garden equipment engines. The crankcase gasket is responsible for creating a seal between the crankcase and the carburetor mount. This prevents air and fuel from leaking out or getting oil mixed into the carburetor. The gasket is under high pressure at all times and can become brittle or break with age, which will need a replacement. It is important to use genuine OEM parts like this one, which is manufactured to specific standards. It is compatible with machines from MTD, RYOBI, Troy-Bilt, Yard Machines, and Yard-Man. This gasket can be used on select models of blower/vacuums, trimmers, edgers, and tillers. It is sold as an individual unit and does not include any hardware or additional parts. To replace this gasket, the engine will need to be completely cooled and gloves should be worn. The crankcase cover will need to be detached from the carburetor assembly, allowing the old gasket to be removed. The new gasket can be put into place and the cover can be reattached. Then, the entire unit can be reassembled and it will be ready to go.

This is the clutch drum that houses the clutch that engages the power tools on more than 50 gasoline-powered lawn and landscape devices. The clutch sits inside this housing, which enables it to rotate. When the RPMs of the engine reach a certain point, the clutch expands and causes the drive shaft of the tool to engage. Among the different kinds of equipment that use this clutch housing are cultivators, edgers, and grass trimmers. The clutch, and therefore the clutch drum, receive a great deal of wear for several reasons: the vibration of the engine, the rapid up and down change of engine revolutions, and resistance met by the tools that are transferred back to the clutch and housing. Signs that the clutch is failing include a slow response to increased engine RPMs and an inability for the power tool to engage the drive shaft. In these cases, the clutch and housing should be replaced in order for the equipment to operate properly again. When choosing a clutch housing, it is important to select one that, like this one, is a genuine OEM certified part. This housing is compatible with Craftsman, Troy-Bilt, MTD, Bolens, Yard-Man, and Ryobi equipment.

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.

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. It should only take a few minutes to perform the replacement. Be sure to wear gloves to protect the hands. This screw is sold individually and does not include any additional parts or hardware.

This is a cylinder assembly that is designed for use in various lawn and garden small engines. The cylinder assembly is a component of the starter assembly and engine. Problems with engine compression are usually the result of the cylinder assembly going bad and needing to be replaced. If the cylinder assembly is not working, the engine may not work at all. One test of the cylinder assembly is to cover the cylinder hole with a finger and pull the starter rope. If the cylinder is not working correctly, no air will come through the hole.If the cylinder assembly is not functioning, it needs to be replaced. The engine will need to be taken apart to get access to this assembly so that it can be removed and replaced. This repair requires work gloves and a basic toolset. Never work on hot engines and make sure the spark plug is removed before working on the machine.This cylinder is an authentic OEM replacement part that is directly sourced from the manufacturer. It is sold as an individual component. The cylinder assembly is designed to fit blowers, cultivators, edgers, trimmers, and vacuums manufactured by Ryobi, Troy Bilt, MTD, Yard Machines, and Bolens.
