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. Re-
place the friction wheel rubber if any signs of
wear or cracking are found.
1. Drain the gasoline from the snowthrower, or
place a piece of plastic under the gas cap.
2. Tip the snowthrower up and forward, so
that it rests on the housing.
3. Remove six self-tapping screws from the
frame cover underneath the snowthrower.
4. Remove the klick pins which secure the
wheels, and remove the wheels from the
axle.
5. Remove the gear shaft from the unit by re-
moving the hex nut and cupped washer
from left side of the frame. See figure 25.
Hold the friction wheel assembly, and slide
the gear shaft out of the unit toward the
right hand side. Refer to figure 18.
6. Remove the six screws from the friction
wheel assembly (three from each side).
Remove the friction wheel rubber from be-
tween the clamping plates.
7. Reassemble new friction wheel rubber to
the friction wheel assembly, tighten approx-
imately 2 turns on each screw until tight. It
is important for the rubber to be assem-
bled symmetrically. See figure 26.
8. Slide the friction wheel assembly up onto
the shift mechanism as shown in figure 18
and slide the gear shaft back into the unit.
Reassemble in reverse order.
