Additional information

This auger housing, part number 684-04167, forms the front enclosure that holds the auger and channels snow toward the impeller and discharge chute. Proper alignment helps maintain steady snow intake and smooth flow through the system.

If the snowblower leaves uneven paths, snow escapes from the front, or you notice cracks, rust-through, or deformation, the auger housing may be damaged. Misalignment can also cause the auger to rub and reduce clearing performance.

Before starting the repair, disconnect the spark plug wire to prevent accidental starting. Support the auger assembly securely, transfer all components carefully to the new housing, and tighten fasteners evenly so the auger spins freely without contacting the housing.
