1. Follow steps 1 through 4 of previous
instructions.
2. Pull idler pulley up, and lift belt off engine pulley
and friction wheel disc. See Figure 23.
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
Figure 25.

CHANGING THE 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.
3. Remove four self-tapping screws from the frame
cover underneath the snow thrower.
4. Using a 7/8" wrench to hold the shaft, loosen,
but do not completely remove, the hex bolt and
bell washer from the left end of the shaft. See
Figure 27.
5. Move the track lock lever to the packed snow
position. See Figure 18.
6. Lightly tap the head of bolt to dislodge the ball
bearing from the right side of frame, then
remove hex bolt and bell washer from left end of
shaft.
7. Sliding the shaft to the right, remove the spacer,
sprocket, and friction wheel assembly from the
shaft. See Figure 27.
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.
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 friction wheel. See Figure 27.
11. Slide the shaft into the hex I.D. of the sprocket,
the spacer, and the left ball bearing, and secure
with the bell washer and hex bolt. See Figure 26.
