Additional Information

Snowblower shear pin 738-04155 connects the auger to the rotating drive shaft and is designed to break if the auger strikes an obstruction such as ice or packed snow. This feature helps prevent transmission and engine damage by disconnecting the auger when excessive force occurs.

If the auger stops spinning while the engine continues running, the shear pin may have broken and should be replaced. Installing a new shear pin restores auger movement and allows the snowblower to operate safely and effectively.

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