Changing Friction Wheel Rubber

Figure 29

Pull the idler pulley away from the drive belt and remove the belt from the engine pulley. You will find the idler pulley in front of the engine and under the belt cover that you removed earlier. See Figure 30.

Working from the underside of the frame, slip belt between the friction wheel and the friction wheel disc. See Figure 30. 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 the belt completely.

Replace new belt. Reassemble following the instructions in reverse order.

Changing Friction Wheel Rubber

Check the rubber on the friction wheel after 25 hours of operation, and periodically thereafter. Replace the 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. See Figure 29.

Remove klick pin securing the left wheel, and remove the 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 31.

Figure 31

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.

Lift the friction wheel assembly out between the axle shaft and the drive shaft assemblies. Remove the six screws from both sides of the friction wheel assembly. Remove friction wheel rubber from between the friction wheel plate. Reassemble new friction wheel rubber to the friction wheel assembly, tightening the six screws in rotation and with equal force. It is important to assemble the rubber on the friction wheel equally for proper functioning.

Insert the pin from the shift arm assembly into the friction wheel assembly and hold assembly
