HOW TO ADJUST OR REPLACE
THE FRICTION WHEEL
How To Check The Friction Wheel
If the snow thrower will not move forward, check the traction
drive belt, the traction drive cable or the friction wheel. If the
friction wheel is worn or damaged, it must be replaced. See
“How To Replace the Friction Wheel” in this section. If the
friction wheel is not worn or damaged, check as follows.
1.
Remove the gas from the gas tank. Stand the snow
thrower up on the front end of the auger housing (see
Figure 39).
WARNING:
Drain the gasoline outdoors, away
from fire or flame.
2.
Disconnect the spark plug wire.
3.
Loosen the bolts on each side of the bottom panel (see
Figure 39).
4.
Remove the bottom panel.
5.
Position the shift speed lever in the lowest forward
speed.
6.
Note the position of the friction wheel (see Figure 40).
The correct distance “A” from the right side of the fric-
tion wheel to the outside of the motorbox is as follows:
Tire Size
Distance “A”
12 and 13 inch
4-1/8” (10.5 cm.)
16 inch
4-5/16” (10.95 cm.)
If the friction wheel is not in the correct position, adjust
as follows.
How To Adjust The Friction Wheel
1.
Position the shift speed lever in the lowest forward
speed.
2.
Loosen hex jam nut on speed select rod. Remove ball
joint from shifter rod (see Figure 41).
3.
Move the friction wheel to the correct position (see
Figure 40).
4.
Turn the adaptor until the ball joint is aligned with the
mounting hole in the shifter rod (see Figure 41). When
