Additional Information

The snowblower impeller pulley, part number 587402401, mounts to the impeller shaft and works with the drive belt to spin the impeller. Proper pulley alignment allows power from the engine to transfer smoothly to the impeller for consistent snow discharge.

You might notice reduced snow throwing performance, the impeller failing to turn when engaged, or belt slippage under load. A pulley that wobbles, makes noise, or shows visible wear can also disrupt belt tracking and power transfer.

Disconnect the spark plug wire before beginning the repair. The impeller pulley installs near rotating components and metal edges, so work gloves can help protect your hands during removal and installation. Make sure the pulley is seated correctly and aligned with the belt before reconnecting the spark plug wire.
