Additional Information

The snowblower worm shaft, part number 917-05351, works with the worm gear to transmit rotational force within the drive or chute control system. As the shaft turns, it allows controlled movement of connected components during operation.

You might notice the chute or driven component binds, moves inconsistently, or stops responding altogether. Grinding noises, uneven motion, or visible wear on the shaft can also signal that the worm shaft is no longer transferring movement smoothly.

Disconnect the spark plug wire before beginning the repair. The worm shaft installs near gears and metal housings, so work gloves can help protect your hands during removal and installation. Make sure the shaft is aligned correctly and rotates freely before reconnecting the spark plug wire.
