Changing the Friction Wheel
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 signs of excessive wear or cracking
are found.
1. Drain the gasoline from the snow thrower, or
place a piece of plastic under the gas cap.
2. Tip the snow thrower up and forward, so that it
rests on the housing.
3. Remove six self-tapping screws from the frame
cover underneath the snow thrower.
4. Remove the wheels from the axle.
5. Using a 7/8” wrench hold the hex shaft and
remove the hex nut and cupped washer and
bearing from left side of the frame. See Figure
14. Hold the friction wheel assembly, and slide
the hex shaft out of the unit toward the right
hand side.
6. Remove the six screws from the friction wheel
assembly (three from each side).
7. Reassemble new bonded friction wheel rubber
to the friction wheel assembly, tighten the six
screws in rotation and with equal force. See
Figure 21.

8. Position the friction wheel assembly up onto the
pin of the shift rod assembly and slide the shaft
through the friction wheel. See Figure 22.
9. Slide the hex shaft into the hex I.D. of the
sprocket, the spacer and the left ball bearing
and secure with the bell washer and hex bolt.
NOTE: Make sure the pin from the shift arm
assembly is assembled to the new friction wheel
assembly.
CAUTION: Check engine and snow
thrower frequently for loose nuts, bolts,
etc. and keep these items tightened.
