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 16.

Back out the stop bolt until the support bracket 
rests on the auger pulley. See Figure 18.

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.

Figure 18

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 9.

Remove six self-tapping screws from the frame 
cover underneath the snow thrower.

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 19.

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.

Figure 19

Move the gear shaft to the right and slide the friction 
wheel assembly from the shaft. See Figure 20.

Remove the four screws from the friction wheel 
assembly. See Figure 20. 

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 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.
