Additional Information

Snowblower shear bolt 588077502 connects the auger to the rotating drive shaft and is designed to break if the auger encounters a solid obstruction such as ice or packed snow. This safety feature prevents transmission or engine damage by disengaging the auger from the drive system when too much force is applied.

If the auger stops spinning while the engine continues to run, a broken shear bolt may be the cause. Replacing the bolt restores proper auger function and ensures safe, reliable snowblower performance.

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