Servicing Friction Wheel Rubber

The rubber on the friction wheel is subject to wear and should be checked after 25 hours of operation, and periodically thereafter. Replace the friction wheel rubber if any signs of wear or cracking are found.

Drain the gasoline from the snow thrower or place a piece of plastic under the gas cap.

Tip the snow thrower up and forward, so that it rests on the housing.

Remove six screws from the frame cover underneath the snow thrower.

Remove the left wheel from the axle.

Remove the four screws securing the left drive cover to the frame. Remove the drive cover from the side of the frame. See Figure 19.

Holding the friction wheel assembly, slide the hex shaft out of the left side of the unit. The spacer on the right side of the hex shaft will fall and the sprocket should remain hanging lose in the chain. See Figure 19.
