Reassemble following the instructions in reverse
order.
NOTE:
The support bracket must rest on the stop bolt
after the new belt has been assembled. See Figure 18.
Servicing Friction Wheel Rubber
WARNING:
Disconnect the spark plug wire
and ground it against the engine to prevent
unintended starting. Drain fuel into an
approved container or place a piece of plastic
film underneath the gas cap to prevent
gasoline from leaking.
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. See Figure 19.
Figure 19
•
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 nut and bell
washer on the left end of gear shaft. See Figure 18.
•
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.
•
Remove the four screws from the friction wheel
assembly. Remove the friction wheel rubber from
between the friction wheel plates. See Figure 20.
Figure 20
•
Reassemble new friction wheel rubber to the
friction wheel plates and hub, tightening the four
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.
