Replace this assembly if the pull cord won't retract, feels loose, or the engine won't turn over when the rope is pulled.

This gasket is a genuine MTD part. It is an insulator gasket meant as a replacement part on tillers, string trimmers, leaf blowers, edgers, and cultivators. The insulator gasket seals the connection between the insulator and cylinder. This gasket is made of durable, heat-resistant plastic. To replace the insulator gasket, a pair of work gloves, wrench, and screwdrivers are necessary. This gasket is a genuine OEM part sourced directly from the manufacturer. It is sold individually. It is compatible with machines made by Craftsman, Cub Cadet, MTD Pro, Troy-Bilt, Yard Machines, and Yard-Man.

Flange bearing for lawn tractors and snow blowers. Replace if you notice excessive noise, vibration, or rough wheel rotation. Verify fit with your model.

A ball bearing is a common type of rolling-element bearing. It will use balls to keep space between the bearing races and eliminate friction and contact between moving parts. Ball bearings used in lawn and garden equipment ensure that axial loads and radial loads are evenly supported and that there is only a limited amount of rotational friction on the component. It distributes weight evenly, but will undergo constant wear and tear from vibration, heat, and friction and will need replacement regularly. This ball bearing is a genuine OEM part suited to use in Craftsman, Cub Cadet, Ryobi, Troy-Bilt, MTD, Huskee, Yard Machines, Bolens, Mastercut, and Yard-Man equipment. It may be needed for repair work done on a lawnmower, snowblower, tiller, edger, or a log splitter.
