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

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

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

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

5.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 19.

6.Working from the underside of the frame, slip belt between the friction wheel and the friction wheel disc. See Figure 22. 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.

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

6.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.

7.Lift the friction wheel assembly out between the axle shaft and the drive shaft assemblies.

8.Remove the six screws from both sides of the friction wheel assembly. Remove friction wheel rubber from between the friction wheel plate.

9.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 symmetrically for proper functioning.
