How to replace a snowblower shear pin

This step-by-step repair guide shows how to replace a snowblower shear pin. If hard-packed snow or a foreign object jams the auger, the snowblower shear pin breaks to protect the engine from damage. Once the shear pin breaks, the auger is no longer attached to the snowblower drive shaft and won’t rotate. Replace the broken shear pin with a manufacturer-approved snowblower part.

You can use the steps in this guide to replace broken shear pins on Craftsman, Husqvarna, Troybilt, Murry, MTD, Toro, Poulan, Ariens and Cub Cadet snowblowers.

Instructions

1. Disconnect the spark plug wire.

Pull the wire straight up and off of the plug. 

2. Remove the broken shear pin

Remove the broken shear pin, using a hammer and nail to completely clear the hole of any pieces.

3. Insert the new shear pin

Realign the holes in the auger and the shaft. Insert the new shear pin and secure it with the bow tie pin.

4. Test the auger

Reconnect the spark plug wire. Start the engine and test the operation of the auger.
