1. Follow steps 1 through 4 of previous instruc-
tions.
2. Pull idler pulley up, and lift belt off engine pulley
and friction wheel disc. See Figure 21.
3. Back out the stop bolt until the support bracket
rests on the auger pulley. See Figure 23.
4. Slip belt between friction wheel and friction
wheel disc. See Figure 23. Remove and replace
belt. Reassemble following the instructions in
reverse order.
NOTE: The support bracket must rest on the stop
bolt after the new belt has been assembled. See Fig-
ure 23.

CHANGING 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.
1. Drain the gasoline from the snow thrower, or
place a piece of plastic under the gas cap.
2. Tip the snow thrower up and forward, so that it
rests on the housing. See Figure 24.
3. Remove six self-tapping screws from the frame
cover underneath the snow thrower.
4. Remove the klick pins which secure the wheels,
and remove the wheels from the axle.
5. Using a wrench to hold the shaft, loosen, but do
not completely remove, the hex nut and bell
washer on left end of gear shaft. See Figure 24.

6. Lightly tap the hex nut to dislodge the ball bear-
ing from the right side of frame. Remove the hex
nut and bell washer from left end of shaft.
7. Slide the gear shaft to the right and slide the fric-
tion wheel assembly from the shaft.
8. Remove the six screws from the friction wheel
assembly (three from each side). Remove the
friction wheel rubber from between the friction
wheel plate. See Figure 25.

9. Reassemble new friction wheel rubber to the
friction wheel assembly, tightening the six
screws in rotation and with equal force.
10. Position the friction wheel assembly up onto the
pin of the shift rod assembly, and slide the shaft
through the assembly. Reassemble in reverse
order.
