Additional Information
Snowblower shear pin kit OEM-738-04155 secures the auger to the rotating drive shaft and is designed to break intentionally if the auger hits a solid object or becomes jammed. This design prevents serious damage to the engine, gearbox, or other drive components by absorbing the force of the impact.
If the auger stops turning while the impeller still spins, one or more shear pins may have broken and should be replaced before resuming operation. Replacing damaged shear pins helps restore proper auger function and prevents further mechanical issues.
Before installation, disconnect the spark plug wire to prevent accidental starting. Remove any broken shear pins, align the auger and shaft holes, and insert new pins securely. Wear work gloves to protect your hands during installation.
