Parts for Craftsman 247299771: Transmission Parts

This ball bearing assembly has a wide variety of uses in a number of gasoline-powered yard tools. Bearings are used to provide smooth, friction-free motion between the rotating parts of equipment where pieces fit together and move. The weight and momentum of the rotating motion are distributed to the ball bearings, which prevents wear on the equipment and allows smooth, repetitive motion. Ball bearings are used in equipment such as tillers and lawn tractors, as well as other power equipment that is self-propelled. The bearings will wear out over time since they are on the receiving end of all the angular momentum of the equipment being used. One of the chief locations where bearing assemblies need to be replaced are the drive wheels of the riding mowers and lawn tractors. The bearings are located in brass housings specifically machined to hold them. Since it can be difficult to remove the old ball bearing assemblies from these housings, it is worth considering simply replacing the entire housing as well as the bearing. These bearings are genuine OEM manufactured replacement parts. They are compatible with MTD, Yard-Man, Troy-Bilt, Husky, Cub Cadet, and Yard Machine lawn tools.

This OEM screw is a fastener with a trimmed six-sided or hexagonal head plus a washer face on the bearing surface. It is one of the most commonly used fasteners. Considered standard hardware, this component has multiple applications and can be used on woodworking, machine assembly, and mechanical repair. The screw is 3/4 long and has a thread size of 5/16 -18. A hex cap screw is installed into tapped holes by turning the head to fit and tighten. This is the fastener of choice in applications where tight tolerance is necessary. This is a genuine factory part sourced from the manufacturer and is sold individually. It can be used with Craftsman, Toro, Cub Cadet, Ryobi, Troy-Bilt, Murray, Yard Machines, MTD, Huskee, Montgomery Wards, Bolens, Yard-Man, and MasterCut brands of lawn maintenance equipment including lawn mowers, snowblowers, tillers, leaf blowers, log splitters, and wood chippers.

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.
