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.

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.

This is an authentic OEM replacement part sourced directly from the manufacturer for use in various small engines. This oil fill tube assembly is part of the oil delivery system. This tube delivers the oil to the oil tank when it is added to the engine. If this tube cracks or deteriorates over time, the oil will not make it to the oil tank or the engine. This could lead to complete engine failure if the leak is not discovered. Oil on the driveway or lawn or smoke coming from under the engine when the lawnmower is running is a sure sign that the tube may need to be replaced.The oil fill tube assembly also houses the dipstick which is used to check the oil level in the mower. If the assembly is leaking, the reading won't be accurate and the lawnmower may be operated without adequate oil which can damage the engine. A screwdriver is needed to replace the oil fill tube. Do not replace this part until the engine has cooled. This oil fill tube assembly is made of black molded plastic and sold as an individual unit. It is designed for use in lawnmowers and other small engines manufactured by Toro, Tecumseh, and Briggs & Stratton.
