9. Reinstall belts by reversing procedure. Make
sure tabs in half sheave are inserted into
mounting grooves in middle pulley section
when reinstalling.
Note: Make sure idler pulleys are aligned
with belts when reinstalling idler
pulley assembly.
10. Readjust belts, refer to Adjusting Auger/Impeller
Drive Belt or Adjusting Traction Drive Belt.
POTENTIAL HAZARD
Improper adjustment may cause injury if
auger/impeller turns when disengaged.
WHAT CAN HAPPEN
Rotating impeller or auger can cut off or
injure fingers or hands.
HOW TO AVOID THE HAZARD
Keep face, hands, feet and any other part of
your body or clothing away from
concealed, moving or rotating parts.
Make certain that impeller brake arm
clearance is maintained.
Do not adjust the auger/impeller drive belt
too tight because it may cause the
auger/impeller to turn when the control
lever is in the disengaged position. If this
occurs, decrease belt tension.
Adjusting Drive Chain
(Fig. 29-31)
The drive chain must be adjusted to maintain 1/8-3/8
of an inch deflection mid span between transmission
and axle sprocket. Check chain deflection after every
25 hours of operation.
1. Pull wire off spark plug and make sure wire does
not contact plug accidentally (Fig. 33).
GB–21
2. Make sure wheels are positioned in rear position,
move shift control into 2nd gear, and tip
snowthrower up onto front edge of
auger/impeller housing.
IMPORTANT: To adjust drive chain, the
snowthrower must be tipped up on front edge
of auger/impeller housing. However, before
the snowthrower is tipped, drain all gasoline
from fuel tank. Refer to Draining Gasoline,
page 18.
3. Check deflection of chain by lifting up on chain
with moderate pressure at mid span. There
should be 1/8-3/8" deflection (Fig. 29). If
deflection is not as specified, an adjustment is
required.
4. Loosen (4) flange head capscrews (2 each side)
securing transmission frame to engine frame
(Fig. 31).
5. Pivot rear of transmission frame until 1/8-3/8"
chain deflection is attained. Retighten flange
head capscrews.
6. Recheck chain deflection.
IMPORTANT: Excessive chain tension may
cause transmission damage.
7. Chain adjustment will affect gearshift lever
alignment. If gear shift lever is not aligned with
Power Shift slot in control panel (Fig. 5, inset),
shift rod length must be adjusted as follows:
A. Disconnect ball joint from transmission
lever and loosen jam nut.
B. Rotate ball joint up or down until gear shift
lever is aligned with Power Shift slot.
C. Reinstall ball joint to transmission lever and
tighten jam nut.

Adjusting Carburetor

The carburetor has been adjusted at the factory, but an
occasional adjustment may be required.
