Servicing Friction Wheel Rubber

•Remove the plastic belt cover on the front of the engine by removing the two self-tapping screws.

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

•Remove six self-tapping screws from the frame cover underneath the snow thrower.

•Pull the idler pulley away from the drive belt and remove the belt from the engine pulley.

•Working from the underside of the frame, slip belt between the friction wheel and the friction wheel disc. You may have to twist the belt flat in order to slide it through the clearance between the friction wheel and the friction wheel disc. Remove and replace the belt. Reassemble following the instructions in reverse order. See Figure 17.

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 wheels 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 18.

•Holding the friction wheel assembly, slide the gear shaft out of the left side of the unit. The spacer on the right side of the gear shaft will fall and the sprocket should remain hanging lose in the chain. See Figure 18.
