•Unhook the support bracket spring from the frame.
NOTE: It may be necessary to loosen the six nuts that connect the frame to the auger housing to aid in belt removal.
•Lift the rear auger belt from the auger pulley, and slip belt between the support bracket and the auger pulley. See Figure 22. Repeat this step for the front auger belt.
•Replace both auger control belts by following instructions in reverse order.

Drive belt
•Follow steps 1 through 4 of previous instructions.
•Pull idler pulley up, and lift belt off engine pulley and friction wheel disc. See Figure 22.
•Using an adjustable wrench, loosen the nut on the stop bolt until the support bracket rest on the auger pulley. See Figure 24.
•Slip belt between friction wheel and friction wheel disc. See Figure 24. 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 24.

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.
•Drain the gasoline from the snow thrower, or place a piece of plastic under the gas cap.
•Tip the snow thrower up and forward, so that it rest on the housing.
•Remove six
•Remove the klick pins which secure the wheels, and remove the wheels from the axle.
•Using an adjustable wrench to hold the shaft, loosen, but do not completely remove, the hex nut and bell washer on the left end of gear shaft. See Figure 25.
•Lightly tap the hex nut to dislodge the ball bearing from the right side of the frame. Remove the hex nut and bell washer from the left end of shaft.
•Slide the gear shaft to the right, then slide the friction wheel assembly from the shaft.
•Remove the six screws from the friction wheel assembly (three from each side). Remove the friction wheel rubber from between the friction wheel plate.
•Reassemble new friction wheel rubber to the friction wheel assembly, tightening the six screws in rotation and with equal force.
•Slide friction wheel assembly back onto the gear shaft. Be sure to align the pin on the shift rod with the hole in the friction wheel assembly. See Figure 23. Reassemble in reverse order.
