Parts for W.W. Grinder 79787: Main Frame Assembly Parts

This flat washer is used to attach the idler pulley in a number of small and medium sized gasoline powered engines. These engines include snow blowers, log splitters, riding mowers, lawn tractors, and chippers. Because the idler pulley is subject to a great deal of resistance when the pulley is engaged, eventually the pulley will wear out. Should there be a squealing sound when engaging the drive, the problem is likely the idler pulley. In these cases, the pulley must be replaced. It is a good idea to replace the surrounding hardware when replacing the idler pulley; tNhis includes the flat washer, which is subject to corrosion during heavy use. To replace the idler pulley, first detach the spark plug cap. If on a mower or tractor, drop the mower deck. Remove the original pulley and install in order: replacement pulley, hex bolt, flat washer, flange nut. Apart from dropping the mower deck, the only tools required to complete this installation may be a 9/16 ratchet and combination wrench. This washer is a genuine OEM replacement part, designed to perfectly replicate the original piece. This washer is compatible with Troy-Bilt, Yard Man, Yard Machines, MTD, and Craftsman devices.

This hex screw is an authentic OEM replacement part sourced directly from the manufacturer. It is used in many different applications in lawn and garden equipment and can be used on many different machines. If the hex screw is missing or loose due to deterioration, a new hex screw should be installed. Hex head screws are removed and replaced using a hex wrench. Screws are used to secure one part of a machine to another part. This hex head screw is not self-tapping, it is designed for pre-drilled holes. Most applications will require a washer and bolt to secure the screw, but there are applications where the screw is inserted into parts that do not have an opening on the other side and so the screw does not need to bolt. Wear gloves when working with screws and outdoor equipment. This hex head screw is made of hardened metal and is sold as an individual unit.
