Additional information

This bearing assembly, part number 12-8789, supports rotating shafts within the drivetrain so they turn smoothly with minimal friction. A properly seated bearing assembly helps maintain alignment and reduces wear on connected components.

If the snowblower makes grinding, growling, or rumbling noises near the bearings, or if vibration increases during operation, the bearing assembly may be worn, damaged, or no longer spinning freely. Excessive play or rough movement when the shaft is turned by hand can also indicate bearing issues.

Before starting the repair, disconnect the spark plug wire or power source to prevent accidental starting. Use the correct tools to remove the old bearing assembly without damaging the shaft, and press or seat the new bearing evenly so it rotates freely.
