Additional information

This snowblower gear housing, left, part number 918-0435, provides a structural enclosure for the left side of the gear assembly and helps keep the gears, shafts, and bearings aligned and protected from snow, ice, and debris. Proper housing support helps maintain smooth operation of the drivetrain and reduces wear caused by contamination or misalignment.

If the gear housing becomes cracked, bent, or loose, the internal gear components can shift out of alignment, which may cause noise, vibration, premature wear, or difficulty engaging the drive or auger systems. You might notice rough operation or unusual sounds if the housing does not hold components securely.

Disconnect the spark plug wire before starting the repair to prevent accidental startup. Gear housing and frame areas can have sharp edges, so wearing work gloves can help protect your hands during installation. Make sure the housing is aligned correctly and all fasteners are tightened securely before using the snowblower.
