Product description

The 8182979 Special Washer is a dedicated fastener component used for securing the transmission spider to the main transmission on Coats tire changers. This washer is engineered with specific dimensions to accommodate the high-torque bolts that link the drive system to the rotating tabletop. Its large surface area provides superior load distribution, preventing the bolts from digging into the spider casting during heavy-duty operation. A cracked or missing washer in this location can lead to transmission wobble, excessive noise, and eventual drive failure. Replacing these washers during a transmission rebuild or spider service is essential for maintaining a stable and vibration-free turntable.
