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.

Flat washer for lawn mowers and outdoor power equipment. Replace if washer is missing, damaged, or corroded to ensure proper fastening and fit.

This washer is compatible with most lawn mowers and lawn tractors. The smooth, round edges fit perfectly with 5/8-inch bolts to attach the bolts to parts on the mower, as necessary. The washer provides a buffer between the bolt and the surface that it is being attached to. They are highly recommended for protecting parts that are being fastened together.The lack of a washer can cause permanent damage to the piece that the bolt is attached to. If the bolt does not have a washer to prevent it from moving and rusting, it can cause the bolt to fail. With products such as lawn mowers, this can spell disaster for both the appliance and its handler. These washers are high-quality and will prevent excess corrosion for the bolt. However, moisture and residue left after use can cause the washers to fail. In this case, a replacement will be necessary. This replacement part is compatible with most lawn mowers and tractors. This includes Ace, Ryobi, and MTD. This is an OEM replacement part sourced directly from the manufacturer. Sold individually.

This is an authentic OEM replacement flange bearing sourced directly from the manufacturer that is a component in many different lawn and garden machines. The flange bearing is used to tightly fit between two connected components. This connection creates an airtight seal. Over time and with normal wear and tear, the flange can become worn and lose the seal. When this happens, the flange will need to be replaced. The flange helps to distribute the weight load in some instances and if it is damaged, the weight would be displaced and could lead to serious energy.Replacement depends on the location of the flange that needs to be replaced. Place the equipment on a flat surface and disconnect the spark plug wire. Take the machine's components off as needed to access the flange and remove it using a pair of pliers. Clean off the components where the bearing was located before installing the new flange bearing. Reassemble the machine using a reverse process.This flange is a heavy-duty part that is sold as an individual item. The flange bearing can be used with lawnmowers and other lawn and garden machines manufactured by Craftsman.
