How to Replace a Snowblower Auger Belt

Step 1: Disconnect the spark plug wire

Pull the spark plug wire straight up and off the plug.

Step 2: Remove the belt cover

Using a socket and ratchet, remove the bolt that fastens the belt cover to the frame of the snowblower. Detach the belt cover.

Step 3: Remove the belt

Pull the auger belt off of the engine pulley.

Step 4: Remove the frame panel

Tip the snowblower forward so it rests on the auger housing. Remove screws that secure the frame panel located between the wheels. Detach the panel to access the drive system components.

Step 5: Remove the belt keeper

Loosen the hex nut and remove the belt keeper.

Step 6: Remove the belt

Note the routing of the belt before removing it. Depress the drive engagement lever with a spring clamp or have a helper hold it closed. Remove the belt from the auger pulley. Rotate the belt 90 degrees so that it slides over the pulley bolt and pull it out. 

Step 7: Install the new belt

Insert the new belt on the auger pulley. Check that the belt is fully inserted in the pulley groove and not on the outside of the break tab or belt keeper.

Reinstall the belt keeper.

Step 8: Reinstall the frame panel

Reinstall the frame panel. Pivot the snowblower upright so it rests on its tires.

Step 9: Install the belt on the engine pulley

Position the belt on the engine pulley and roll it in place. Reinstall the belt cover.

Step 10: Test the snowblower

Reconnect the spark plug wire. Fill the tank with gas and test the snowblower.
