Additional Information

Snowblower shear pin 738-04124A-50 secures the auger to the rotating drive shaft and is designed to break intentionally if the auger hits a solid object or becomes jammed in compacted snow. This safety mechanism helps prevent damage to the transmission and engine while protecting other key drive components.

If your snowblowers auger stops turning but the impeller continues to spin, one or more shear pins may be broken and need replacement. Keeping a spare pack on hand ensures you can quickly replace broken pins and resume snow clearing without downtime.

Before installation, disconnect the spark plug wire to prevent accidental starting. Remove any broken shear pins, align the auger and shaft holes, and install the new pins securely. Wear work gloves to protect your hands during replacement.
