This is a genuine replacement bolt that is designed specifically for use on select lawn tractors. This tractor bolt is a specialty piece of hardware designed for use on the steering segment gear. This screw holds the gear in place and is exposed to constant vibrations and repetitive motion as a result. Over time, that can result in damage, wear, or even total breakage of the bolt and require a replacement. If the bolt isn't functional or is missing, the steering segment gear will not be secured and that can lead to further damage if left unattended. Using a genuine replacement part like this will guarantee an exact fit for compatible models. This genuine OEM gear bolt is manufactured by MTD. It is compatible with lawn and garden equipment from RYOBI, HUSKEE, Troy-Bilt, Bolens, Yard Machines, Yard Man, and Cub Cadet, along with select models from MTD. The bolt works for more than 100 compatible models. It is made of durable metal and sold as an individual unit. A wrench or socket will be required to replace this part. Always wear gloves when performing repairs on lawn and garden equipment and allow the engine to cool before doing any work.

There are multiple uses for the 5/16-18 Hex Screw. It is often used with small gasoline-powered yard equipment such as lawn and garden machines. While hex screws such as these may be used in edgers and snowblowers, the most frequent use this screw is in yard tractors. This variety of screw is commonly used in attaching the various appendages of gas-powered equipment to a central operating platform. In particular, these hex screws are used to secure the engine block of power tools to the frame or housing of the equipment. Once in place, these fasteners have an almost unbreakable strength to them. This is so much so the case that often, in order to detach the engine manifold and repair the inner workings of an engine, the bolts must be chiseled or cut loose. In such cases, it is necessary for the bolts to be replaced during reassembly. Manufacturers insist that genuine OEM replacement parts be used in the rebuilding process. These replacement parts were manufactured to the same exacting specifications used to make the original screws. These OEM screws are compatible with equipment made and sold by Yard-Man, Cub Cadet, Troy-Bilt, Husky, MTD, Bolens, and Yard Machines.

This is a flanged lock nut. It’s designed to apply tension, typically on a joint that needs to have a certain amount of flex. As such, it’s mostly used on snowblower chutes and lawnmower handles. They can remain in place, but with a forgiving connection that can take a beating. The nut size is 3/8, with a thread size of 16. A lock nut will generally last for many years. However, the silicone ring inside will wear down if it’s frequently tightened and loosened. It needs to be replaced when it will no longer reliably remain in place. Generally, this begins as a symptom of slight slippage and worsens as time goes on. Thankfully, whether it’s being used on a snowblower or a lawnmower, this nut is generally straightforward to access. Simply unscrew the old nut, then screw the new nut on until it’s nice and tight. Our flanged lock nuts are genuine OEM MTD nuts, and they are sold individually.

Wear work gloves when completing this repair to prevent injury. The engine should be completely turned off and cooled down. This part is sold individually and is sourced directly from the manufacturer. This is a genuine OEM replacement part.

Cotter pins are simple but very effective fasteners used primarily to hold wheels in place on mowers. This is particularly true of the front wheels on riding mowers. Cotter pins are very light and can become overly pliable after extensive use. In some cases, the front wheels of a mower, which are the guide wheels that steer the device, become difficult to manage. The cure for this situation is often simply the replacement of the cotter pins that are not holding the guide wheels adequately in place. Before attempting to remove the pins, it is essential that the spark plug boot is moved so that the mower cannot be started. This is an important safety step because the repairer will be getting under the mower near the blades. The back wheels should be blocked so the mower cannot move, then the front end placed up on blocks. Remove the mower's hubcaps to gain access to the axle spindles. Straighten the legs of the pin so that when the curved portion of the cotter pin is grasped with pliers and it can be pulled straight back and be removed. The spindle, washers, and wheels should be checked for wear before the new pin is placed and secured. This OEM cotter pin is compatible with Bolens, Yard-Man, Craftsman, Yard Machines, Cub Cadet, Turf King, Troy-Bilt, Huskee, Toro, Ryobi, MTD, MasterCut, Murray, and Montgomery Wards.

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.

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.
