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
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.
