Parts for Mtd 243687: Air Duct Assembly Parts

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.

This washer is a genuine MTD replacement part for lawn and garden appliances that are operated by small engines, such as lawn tractors, snowblowers, chipper shredders, leaf blowers, and lawn mowers. The purpose of a washer is to protect and insulate nuts, bolts, and other types of fasteners, preventing these fasteners from gradually loosening. A washer will have to be replaced in the event that it is lost or misplaced, a common occurrence given its extremely small size and its ability to slide off without calling any attention to its absence. Other reasons to replace a washer could include general wear and tear or visible damage in the form of erosion, bending, or cracking metal as a result of overuse or overexposure. If a washer is subject to any of this kind of damage, it should be replaced immediately to avoid nuts and bolts coming loose and separating the materials that they protect and hold together. Remember that gloves must always be worn when handling, repairing, and operating outdoor equipment. This washer part is compatible with the brands MTD, Yard Machines, Cub Cadet, and Yard Man.

This carriage bolt is a self-locking fastener made for use in round or square holes to attach metal to metal in outdoor equipment. These bolts provide an added safety feature because they can only be removed from one side. Carriage bolts can carry a large amount of weight, which makes them ideal for use in outdoor yard equipment. Carriage bolts may be used to attach a lawn mower's arm to the side support and other similar applications. If the bolt needs to be replaced, removal and installation are simple. Use a wrench to loosen the nut holding the washer and bolt in place. Once the nut is loose, the bolt can be unthreaded by hand and pulled out of the hole. To install, push the bolt back through the hole. If the fit is too tight to install by hand, use a hammer to tap it in place. Reinstall the washer and nut and tighten with a wrench.This carriage bolt is designed for use in lawnmowers, snowblowers, and lawn tractors manufactured by Craftsman, Bolens, Yard Machines, Yard-Man, and MTD. This is a genuine OEM product that comes directly from the manufacturer. Note: It does not come with a nut or washer.

Shoulder screws are a type of fastener used in many types of lawn and garden equipment. Also called stripper bolts or shoulder bolts, they have a head, threads, and an unthreaded shoulder.

Shoulder screws are made of durable metal but can still experience breakage or damage. When this occurs, the screws will need to be replaced. A wrench can be used to remove the damaged shoulder screw. First, visually inspect the shoulder screw to look for damage or corrosion. Sometimes, the screw will be entirely broken.
