• Back out the stop bolt until the support bracket
rests on the auger pulley.
• 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.
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.
• Tip the snow thrower up and forward, so that it rests
on the housing.
• 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

• 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 23.
• 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 23.
• 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.
