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
