Additional Information

The snowblower cotter pin, part number 727500, slides through a drilled hole in a bolt, shaft, or pin to lock a nut or component in place. Its bent ends help resist movement so the secured parts remain stable during operation.

If components loosen, fasteners back off over time, or you hear rattling or shifting near connections during use, a bent, worn, or missing cotter pin may be allowing hardware to move. Visible gaps at connection points or pins that no longer stay tightly bent can also indicate cotter pin issues.

Disconnect the spark plug wire before beginning the repair. The cotter pin installs near metal edges and moving parts, so work gloves can help protect your hands during installation. Insert the pin fully through the hole and bend the ends around the shaft or bolt to lock it before reconnecting the spark plug wire.
