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

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.
