Whirlpool Dryer Motor Pulley (WP8066184)

The Whirlpool Dryer Motor Pulley transfers power from the motor to the drive belt so the drum can turn at the correct speed. It mounts on the motor shaft and guides the belt in a stable path during start-up and while drying. Common causes of failure include normal wear on the pulley grooves, a pulley that loosens on the motor shaft, or damage from a belt that has been slipping, frayed, or run out of alignment. Heat, lint buildup, and heavy loads can speed up wear and lead to noise or loss of drive. If you are troubleshooting drum rotation or belt tracking issues, these symptoms can point to a motor pulley problem: The motor runs but the drum does not turn. A burning rubber smell from a slipping belt. Squealing, chirping, or grinding noises near the motor area. The belt rides off the pulley or shows rapid fraying along one edge. The dryer starts, then stops as the belt slips or binds. Visible wobble, cracking, or worn grooves on the pulley.
