HOW TO ADJUST OR REPLACE
THE FRICTION WHEEL
How To Check The Friction Wheel
If the snow thrower will not move for-
ward, 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 Re-
place the Friction Wheel" in this section.
If the friction wheel is not worn or dam-
aged, check as follows.
1. Run the engine until the fuel tank is
empty and the engine stops.
2. Stand the snow thrower up on the
front end of the auger housing
(see Figure 48).
3. Disconnect the spark plug wire.
4. Loosen the bolts on each side of
the bottom panel (see Figure 48).
5. Remove the bottom panel.
6. Position the shift speed lever in
the lowest forward speed.
7. Note the position of the friction
wheel (see Figure 49). The correct
distance "A" from the right side of
the friction wheel to the outside of
the motorbox is as folows:
Tire Size Distance "A"
12 and 13 inch 4-1/8"
16 inch 4-5/16"
If the friction wheel is not in the
correct position, adjust according to
the following instructions.
