This hex nut is designed for use with select trimmers and mowers. It is a standard hardware part that may have multiple applications depending on the type of unit and model. The nut is typically used to secure engine components or housing elements to provide safe use of the machine. These nuts are durable, but they are small and can become lost during other repairs. The constant exposure to vibrations and use can also cause them to strip or become damaged over time. Either way, a replacement with this genuine hex nut will resolve the issue and get equipment back in working order. This genuine OEM hex nut is manufactured to exact standards and sourced from the manufacturer. It can be used with trimmers and mowers from RYOBI, MTD, Bolens, Troy-Bilt, Yard Machines, Huskee, Yard Man, and Cub Cadet. Check the parts diagram for exact application and location of this nut and note that it may have multiple uses on select models. This hex nut is sold individually, and additional nuts will require the purchase of multiple pieces. In order to replace this nut, a hex socket wrench and driver will be required. Always wear gloves for safety.

This flat washer is used to attach the idler pulley in a number of small and medium sized gasoline powered engines. These engines include snow blowers, log splitters, riding mowers, lawn tractors, and chippers. Because the idler pulley is subject to a great deal of resistance when the pulley is engaged, eventually the pulley will wear out. Should there be a squealing sound when engaging the drive, the problem is likely the idler pulley. In these cases, the pulley must be replaced. It is a good idea to replace the surrounding hardware when replacing the idler pulley; tNhis includes the flat washer, which is subject to corrosion during heavy use. To replace the idler pulley, first detach the spark plug cap. If on a mower or tractor, drop the mower deck. Remove the original pulley and install in order: replacement pulley, hex bolt, flat washer, flange nut. Apart from dropping the mower deck, the only tools required to complete this installation may be a 9/16 ratchet and combination wrench. This washer is a genuine OEM replacement part, designed to perfectly replicate the original piece. This washer is compatible with Troy-Bilt, Yard Man, Yard Machines, MTD, and Craftsman devices.

Hex lock nut secures bolted joints on outdoor lawn equipment. Replace if threads are stripped, nut is missing, or won't hold proper tension.

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.

A fuel cap assembly is a component often seen on lawnmowers and other lawn and garden equipment. It is made of durable black plastic and is used to ensure that fuel doesn’t spill out of the fuel tank. Over time, fuel cap assemblies can begin to wear out and cause problems. Sometimes this results in a cap that doesn’t tighten all the way or there may be a fuel smell when using a lawnmower or snowblower. If fuel is leaking, the cap doesn’t fit right, or the cap seems damaged, it’s best to replace it with a new component. This is a simple process that involves removing the original fuel cap assembly and fitting the new assembly to the lawn machine. This fuel cap assembly is a genuine OEM component that comes directly from the manufacturer. It is an individual part that is compatible with MTD, Murray, Cub Cadet, Bolens, Yard-Man, and Yard Machines lawnmowers, snowblowers, chipper shredders, and tillers.
