•Unhook the idler spring from the hex bolt on the auger housing. See Figure 21.
•Back out the stop bolt until the support bracket rests on the auger pulley.
NOTE: Loosening the six nuts that connect the frame to the auger housing may aid in belt removal.

•Lift the auger belt from the auger pulley and slip belt between the support bracket and the auger pulley. Repeat this step for the front auger belt.
See Figure 21.
•Replace the auger drive belts by following instructions in reverse order.
Drive Belt
•Follow the first four steps of the instructions for servicing the auger belts.
•Pull the idler pulley up and lift the belt off the engine pulley and friction wheel disc. See Figure 20.
•Back out the stop bolt until the support bracket rests on the auger pulley.
•Slip the belt between the friction wheel and drive disc. Remove and replace the 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.
Servicing 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.
•Tip the snow thrower up and forward, so that it rests on the housing.
•Remove six
•Remove the click pins which secure the wheels, and remove the wheels from the axle.
•Using a 7/8" wrench to hold the shaft, loosen, but do not completely remove, the hex bolt and bell washer on the left end of gear shaft. See Figure 22.

•Lightly tap the hex nut to dislodge the ball bearing from the right side of frame before removing the hex nut and bell washer from left end of shaft.
•Move the gear shaft to the right and slide the friction wheel assembly from the shaft. See Figure 23.
•Remove the six screws from the friction wheel assembly (three from each side). Remove the friction wheel rubber from between the friction wheel plates. See Figure 23.
•Reassemble new friction wheel rubber to the friction wheel plates and hub, tightening the six screws in rotation and with equal force.
•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.
