Traction and Impeller Controls Traction Cable
Adjustment (cont'd)
1.
Check for proper tension by pushing the front
housing
of
the snowthrower against a protected
wall. Proper traction belt tension is achieved when
the wheels spin on a concrete floor in second gear,
but do not in fourth.
2.
Adjust tension by loosening the two jam nuts at
the upper end of the traction cable. To increase
tension, rotate the nuts
so
that the
end
of
the
sheath moves down. To decrease tension, the end
of the sheath must be moved closer to the traction
lever.
CAUTION:
Do
not overtighten because
it
may
cause the snowthrower to creep when the
traction lever is
in
the disengaged position.

Traction and Impeller Controls Impeller Cable
Adjustment
The impeller drive system will in some conditions
transmit most of the power available from the engine.
Therefore the tension
on
this belt is fairly high.
1.
Depress the impeller lever. Proper tension is
achieved when there is
.25
mm
(.010”)
clearance
between coils
of
the impeller cable spring.
See
Figure
53.

2.
Adjust tension by loosening the
two
jam nuts at
the top of the auger cable. Increase tension by
rotating the nuts
so
that the end
of
the sheath
moves down. Decrease tension by moving the
end of the sheath toward the impeller lever.
NOTE: Do not overtighten as
it
may cause the
impeller and auger to turn when the lever is in the
disengaged position.
