Parts for Craftsman 107889650: Drive Parts

The shear bolt kit provides a special type of bolts used to connect the auger blade to the axle. The bolts are meant to provide protection in the event the blade becomes stuck or hits something hard, such as a chunk of ice. At that time, the force will cause the bolt to snap instead of breaking other parts of the machine what would be expensive to replace. The shear bolts are meant to break under certain conditions. When this happens, the owner will need to order replacements. It is also a good idea to check the condition of the bolts occasionally to ensure they are still in good working order and to replace them if they show signs of wear or potential early breakage. The bolts are easy to replace. These genuine OEM replacement shear bolts are sold in pairs and include nuts and washers. Compatible brands include Craftsman, Husqvarna, Snapper, Simplicity, Poulan Pro, Briggs & Stratton, and Murray. Buyers should be sure they are getting the right bolts for their make and model. They may also want to purchase some additional bolts to have on hand for the future.

This genuine OEM replacement friction disc wheel is designed to fit a wide range of snowblower engines. A friction wheel attaches to the friction disc of a friction drive transmission. This style of transmission is common to many lawn appliances. Rather than relying on chains or sprockets, a friction wheel transmission uses two rotating wheels to drive the axle. If one wheel is damaged, the transmission will seize up, and the engine will not run. Over time, friction plates will wear down through repeated use, and the transmission will eventually give out. Signs of a failed transmission include noticeable vibrations, poor engine performance, out-of-place revving, and a slipping engine. Replacing the friction disc will require a socket wrench to remove the wheel and hex shaft, as well as a pair of pliers to pry away any clips securing those parts into place. Be sure not to lose any of these small components, as they are needed for reassembly. Before starting any repair, be sure to drain any fuel from the appliance. This part is compatible with Murray, Snapper, and Simplicity snowblowers and is sourced from the original manufacturer. As a top of the line replacement part, it ships individually.
