Additional Information

Snowblower belt cover 631-05321 protects the drive belt assembly from snow, dirt, and debris, helping maintain smooth power transfer from the engine to the auger and drive systems. The cover also shields the belt from moisture and corrosion, extending the life of the belt and pulleys.

If the existing belt cover is cracked, warped, or missing, it should be replaced to prevent exposure of moving parts and maintain safe operation. A properly fitted cover keeps the drive components secure and clean, reducing maintenance needs over time.

Before installation, disconnect the spark plug wire to prevent accidental starting. Remove any damaged cover, align the new one with the mounting holes, and fasten it securely. Ensure all components are properly enclosed before resuming operation. Wear work gloves to protect your hands during the repair.

Belt cover 631-05321 replaces part numbers 731-04792, 731Z04792F, and 731-04792A.
