How To Adjust Or Replace The Friction
Wheel
NOTE: Take special note of the position of
the washers (17) .
If the snow thrower will not move forward, check
the traction drive belt for wear or damage. If the
traction drive belt is worn or damaged, replace
the belt as follows.

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.

The augers are secured to the auger shaft with
special shear bolts. These shear bolts are de-
signed to break and protect the machine if an
object becomes lodged in the auger housing.
Do not use a harder bolt as the protection pro-
vided by the shear bolt will be lost.
