Additional Information

Snowblower shear bolt 710-0891 connects the auger to the rotating drive shaft. The bolt is designed to break or shear off if the auger encounters a heavy obstruction, preventing damage to the gearbox and engine. This safety feature protects key components from costly repairs.

If the auger stops turning or you find a missing or broken bolt, the shear bolt needs replacement before operating the snowblower. Always use the correct replacement size and grade to maintain proper protection.

Before installation, disconnect the spark plug wire to prevent accidental starting. Remove any broken bolt pieces, align the holes in the auger and shaft, and insert the new shear bolt. Secure it with the appropriate nut and tighten snugly without overtightening. Wear work gloves to protect your hands during the repair.

Shear bolt 710-0891 replaces part numbers 910-0891 and 710-891.
