Servicing 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 rests
on the housing.
• Remove the six self-tapping screws from the frame
cover underneath the snow thrower.
• Using a 7/8" wrench to hold the shaft, loosen, but
do not completely remove, the hex bolt and washer
on the left end of the shaft. See Figure 19 and
Figure 20.
• Lightly tap the hex bolt to dislodge the ball bearing
from the right side of frame before removing the hex
bolt and washer from the left end of the shaft.
• Move the 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 18
