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 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.
