ADJUSTING REAR
SPRING TENSION
Rear spring tension adjustment is
accomplished by rotating the adjusting
cams. Position 3 provides the stiffest
ride, and position 1 is for the light
driver or slow-speed trail riding. Posi-
tion 2 is for the average operator under
normal conditions. Always rotate the
cam from the lighter position to the
heavier position.

Using a 13/16 in. wrench, rotate the
cam until it is in the desired position. To
stiffen the ride, rotate the cam so as to
raise the spring end. Make the adjust-
ment on the other cam and be sure both
cams are adjusted equally.
SKI ALIGNMENT
The skis have been aligned during setup
of the snowmobile. Ski alignment usu-
ally will not change unless a rock or
similar hard object is hit while the
snowmobile is being operated. Arctic
Cat recommends that the ski alignment
be checked once a week.
Checking Ski
Alignment
1. Turn the handlebar to the straight-
ahead position.
2. Measure the distances to the inside
edges of the skis. Make sure the
measurements are taken behind the
front mount bracket and ahead of
the rear mount bracket.

„
NOTE: Ski alignment is correct
when the skis are parallel to each
other (equal measurements front
and rear) or when the skis have
up to a maximum of 6 mm (1/4 in.)
“toe out” (front measurement 6
mm (1/4 in.) more than rear mea-
surement).
! CAUTION
Never force the adjustment cams
from the low position to the high
position. Cam damage may
occur.
