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. See Figure 17. Repeat this step for the front auger belt.
•Replace the auger drive belt by following instructions in reverse order.
Drive Belt
•Follow the first four steps of the instructions for servicing the auger belt.
•Pull idler pulley up, and lift belt off engine pulley and friction wheel disc. See Figure 18.
•Back out the stop bolt until the support bracket rests on the auger pulley. See Figure 20.
•Slip belt between friction wheel and friction wheel disc. See Figure 20. 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 20.
Servicing Friction Wheel Rubber
WARNING: Disconnect the spark plug wire and ground it against the engine to prevent unintended starting. Drain fuel into an approved container or place a piece of plastic film underneath the gas cap to prevent gasoline from leaking.
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 nut and bell washer on the left end of gear shaft. See Figure 21.

•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.
•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 22.
