When operating the snowmobile in
deep snow, it may be necessary to vary
stopper strap length and/or riding posi-
tion, to change the angle at which the
track rides on the snow. Operator's fa-
miliarity with the various adjustments
as well as snow conditions will dictate
the most efficient combination.
Generally, a longer stopper strap set-
ting gives better performance in deep
snow on a flat landscape.
Rear Spring Preload
Rear spring preload has an effect on
comfort, ride height and load compen-
sation.
Also, adjusting rear spring preload
shifts more or less weight to the snow-
mobile front end. As a result, more or
less weight is applied to the skis. This
has an effect on performance in deep
snow, steering effort and handling.
Slight suspension bottoming occurring
under the worst riding conditions indi-
cates a good choice of spring preload.
ACTION RESULT
Firmer rear suspension
Higher rear end
More bump absorption
capability
Increasing
preload
Heavier steering
Softer rear suspension
Lower rear end
Less bump absorption
capability
Lighter steering
Decreasing
preload
Better performance and
handling in deep snow
Refer to the following to determine if
preload is correct.

TYPICAL — PROPER ADJUSTMENT
A. Suspension fully extended
B. Suspension has collapsed with driver,
passenger(s) and load added
C. Distance between dimension “A” and “B”,
see table below
”C” WHAT TO DO
50 to 75 mm
(2to3in)
No adjustment required
More than
75 mm (3 in)
Adjusted too soft,
increase preload
Less than
50 mm (2 in)
Adjusted too firm
,
decrease preload
