Adjusting Rear Spring Pre-Load
Proper adjustment of rear spring
pre-load is necessary to get the most
comfortab le ride. The chart is
designed to help in setting up rear
spring pre-load; however, riding
style is the single greatest factor in
determining rear spring require-
ments.

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
accomplished by rotating the adjust-
ing 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 posi-
tion.
! CAUTION
Never force the adjustment cams
from the low position to the high
position. Cam damage may occur.

To rotate an adjusting cam, use the
Cam Position
spark plug wrench from the tool kit.

Rotate the wrench until the cam is in
the desired position. To stiffen the
2
ride, rotate the cam so as to raise the
3
spring end. Make the appropriate
adjustment on the other cam.
Articulating Skid Fame
(Bearcat Wide Track STD)
The rear articulating portion of the
skid frame has two adjusters which
control the amount of travel in the
rear suspension.
These two adjusters have been pre-
set at the factory and should require
no further adjustment.
If adjustment is ever required, rotate
the two adjusters equally to permit
12.5-25 mm (1/2-1 in.) travel of the
articulating portion of the suspen-
sion.
