•Follow the first six 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 19.
•Back out the stop bolt until the support bracket rests on the auger pulley. See Figure 21.
•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. See Figure 21.

Replacing 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. Refer to Figure 10.
•Remove six
•Using a 7/8" wrench to hold the shaft, loosen, but do not completely remove, the hex bolt and cupped 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 23A.
•Remove the four screws from the friction wheel assembly. See Figure 23B.
•Remove the friction wheel rubber from between the friction wheel plates.
•Reassemble new friction wheel rubber to the friction wheel plates and hub, tightening the four screws in rotation and with equal force.
