Parts for Troy-Bilt 721: Engine / Gas Tank Parts

This power cord extension is a genuine MTD part, sold individually. This power cord extension can be used as a replacement part for a snowblower. This power cord extension lengthens the reach of the power cord so that the appliance can be used from a greater distance from its direct power source while it is plugged in. The power cord extension might have to be replaced at some point if the cord suffers damage that renders it beyond functionality. This could occur if the cord is frayed, if it gets wet, or if it is punctured, torn, scratched, or eroded to the point that it does not power on the snowblower when properly plugged in. Remember to wear work gloves as a safety precaution while repairing or replacing parts within an outdoor appliance. This is an OEM part sourced directly from the manufacturer. It is sold individually. This power cord extension is compatible with the following outdoor appliance brands: MTD, Toro, Cub Cadet, Ryobi, Tecumseh, Lawn Boy, Huskee, Montgomery Wards, Bolens, Yard Man, Troy-Bilt, and Yard Machines.

This lock washer is used frequently for a number of applications on power yard equipment. The size, 5/16, is the default for many small engine housing and manifold applications. Lock washers are used with machined bolts to fasten engine blocks to the housing of the equipment being used. The compressed washer is able to handle the constant vibration of the small gasoline engine without losing the seal between the screw or bolt and the housing. Typically these lock washers only need to be replaced when they are misplaced during repairs or when the screws that attach them have to be chiseled or cut away, meaning the washers are destroyed as well. These OEM certified replacement washers have been manufactured to the same specifications as the originals they are replacing. In addition to lawn mowers, lock washers of this type and size are frequently used on blowers, lawn tractors, cultivators, snowblowers, and trimmers. Brands compatible with this type of washer are Murray, Husky, Poulan, Bolens, Yard-Man, Cub Cadet, Troy-Bilt, Yard Machines, MTD, and Ryobi.

Seals the fuel tank on lawn tractors, mowers, and snow blowers. Replace if cracked, loose, or leaking to prevent fuel evaporation and contamination. Verify fit with your model number.

The drive V-belt, manufactured by Craftsman, is used in one- and two-stage snow blowers as well as tillers. This is a drive belt that connects the engine to the auger of the tiller or snowblower via a pulley at either end. This turns the blades of the tiller or the auger blades of the blower to expel snow. As a flexible, hardened rubber part connecting other moving parts, a V-belt is considered “replaceable,” meaning that users should expect to have to replace this part during normal use of the equipment. Signs that a drive V-belt may be going bad are a squealing sound when the blower's auger or the tiller's blades are first engaged, or if the auger is slow to engage and loses power during use. To replace the V-belt, the equipment must be secured and the spark plug caps removed. Tilt the device to reveal the location of the belt. It must detached from the engine pulley and the transmission pulley. When replacing the V-belt, before tightening the pulley, make sure all moving parts are properly aligned. This genuine OEM part is compatible with machines sold by MTD, Yard Man, Craftsman, and Yard Machine.
