Description
Coats 8184674 Adjustable V-Belt Motor Pulley for Coats Tire Changers
This adjustable v-belt pulley mounts to the motor shaft on Coats tire changers and connects the motor (air or electric) to the transmission, enabling the turntable to rotate. The pulley is adjustable: turning the two sides on the threaded hub increases or decreases the pitch diameter, which varies turntable speed and extends drive belt life. Inspect and replace the pulley when the belt slips, the turntable speed is inconsistent, or the pulley groove shows visible wear or cracking.
