Additional Information

Snowblower auger shaft bearing housing 790-00087A-0637 protects the auger shaft bearing from dirt, moisture, and debris while maintaining proper bearing alignment. It helps ensure smooth auger rotation and extends the life of the bearing and auger assembly.

If the housing becomes cracked, bent, or corroded, the auger bearing may be exposed to the elements, leading to premature wear or failure. Replacing a damaged housing helps maintain efficient auger movement and prevents costly repairs to the auger system.

Before installation, disconnect the spark plug wire to prevent accidental starting. Remove the auger assembly as necessary, position the new bearing housing over the bearing, and secure it with the correct hardware. Ensure proper alignment before reassembling the snowblower. Wear work gloves to protect your hands during the repair.
