This genuine OEM replacement auger bearing flange fits a wide range of snowblowers. The auger is the part of a snowblower that scoops up and moves it away from the area being cleared. It is held in place by a bearing, and this flange connects to the bearing to reduce friction and motion. This flange helps prevent grinding, which would degrade the bearing and cause the auger to stop working effectively. Bearings and flanges receive a lot of wear and tear because they are built to absorb friction. Over the natural course of an appliance's life, bearings and flanges will normally wear down and need replacing. If a bearing flange snaps, the auger will no longer turn, and the snowblower will not move snow. To replace a bearing flange, use a socket wrench to gain access to the belt cover and then detach the auger housing. Remove the pulley and thread, then take the auger out of its housing. Pull out the old auger bearing flange and install the new part. This part is compatible with Yard Man, Troy-Bilt, Craftsman, Bolens, MTD, Huskee, and Yard Machines snow blowers.

With small gasoline-powered tools that require control panels, this hex screw attaches the panel to the handles of the tools. Machined to be durable, important screws such as these take a real beating. In their locations at critical points on the handle, the hex screws are considered "wear items," and thus periodically, they must be replaced. The control panel itself is often a location of extreme forces, jostling, and abrupt movement in unpredictable directions. The constant movement, with sheet metal rubbing against the hex screws from every direction, make wear inevitable. The manufacturers recommend that spare screws of this type be kept on hand if the heavy use of the equipment is expected.
