Additional Information

Snowblower shear bolt 710-0890A connects the auger to the rotating drive shaft and breaks intentionally when the auger hits a solid object such as ice or packed snow. This helps prevent damage to the gearbox or engine by disconnecting the auger from the drive system.

If the auger stops spinning while the engine continues to run, the shear bolt may have sheared and should be replaced. Replacing it restores proper auger movement and ensures safe, efficient operation during snow removal.

Before replacing the bolt, disconnect the spark plug wire to prevent accidental starting. Remove any broken bolt pieces, align the auger holes with the drive shaft, and install the new bolt securely. Tighten it as needed and wear work gloves to protect your hands during installation.
