DRIVE BELT

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.
