5.Now moving to the other side of the snow thrower again, slide the belt off the crankshaft.
6.Replace with new belt, first sliding it through the crank shaft, then working it around the groove of the drive pulley and finally wrapping it around the engine pulley from where the old belt was removed. Once the belt is firmly placed on the pulleys, make sure to remove the screwdriver from the idler.

Friction Wheel Rubber
1.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.
2.Drain the gasoline from the snow thrower, or place a piece of plastic under the gas cap. Move shift lever to the R2 position.
3.Tip the snow thrower so that it rests on the housing. Remove the
4.Remove bolt securing the right wheel, and remove the wheel from the axle.
5.Remove the four screws securing the right drive cover to the frame. Remove the drive cover from the side of the frame. See Figure 18.

9.Reassemble new friction wheel rubber to the friction wheel assembly, tightening the four screws in rotation and with equal force. See Figure 20.
IMPORTANT: Assemble the rubber on the friction wheel equally for proper functioning.
