Adjusting Rear Spring Pre-
Load
2000/3000
Proper adjustment of rear spring pre-load
is necessary to get the most desirable
ride. The chart is designed to help in set-
ting up rear spring pre-load; however,
riding style is the single greatest factor in
determining rear spring requirements.
NOTE: These cam position set-
tings are suggestions only. Personal
riding style will greatly influence
cam position settings. Spend time to
determine setting preferences.
Rear spring pre-load adjustment is accom-
plished by rotating the adjusting cams.
Position 3 provides the stiffest ride, and
position 1 is for the light driver or slow-
speed trail riding. Position 2 is for the
average operator under normal conditions.
Always rotate the cam from the lighter
position to the heavier position.

To rotate an adjusting cam, use the spark
plug wrench from the tool kit. Rotate the
wrench until the cam is in the desired
position. To stiffen the ride, rotate the cam
so as to raise the spring end. Make the
appropriate adjustment on the other cam.

In addition to the three cam positions,
there are five additional positions which
the operator can choose from. The spring
slide is mounted in location #1 during the
production of the snowmobile which is
the lowest spring rate. Every hole the
spring slides go up, so does the spring
rate, thus increasing the amount of load
carrying capability. Make sure the spring
slides are in the same mounting location
on either side.
