Additional Information

Snowblower shear bolt kit OEM-710-0890 secures the auger to the drive shaft and is made from soft metal that shears on impact to protect the engine and transmission if the auger hits a hard object or binds in packed snow. This design prevents costly damage and keeps your snowblower operating safely.

If the auger stops turning while the impeller continues to run, the shear bolts may have broken and should be replaced before operating the machine again. Regular inspection and replacement of worn or missing shear bolts help ensure dependable performance throughout the winter season.

Before installing, disconnect the spark plug wire to prevent accidental starting. Remove any broken bolts, align the auger and shaft holes, and insert new bolts with the provided lock nuts. Tighten securely and wear work gloves to protect your hands during installation.
