FRONT SUSPENSION SETTINGS
Overview
The following topics are outlined involving the front
suspension:
• Maximum Width
• Handlebar Centering
• Setting Camber
• Ski Toe Adjustment
Before making any adjustments to the front suspension,
inspect all components for damage. Replace any broken,
bent or worn components before making any adjustments.
Verify the sway bar and related hardware are not bent,
loose, or broken. Inspect the shocks.
The shocks on the front suspension are the only
components that limit maximum control arm extension.
Bent shock rod(s) adversely affect front suspension
settings and handling.
Never install longer (when fully extended) shocks.
Installing longer shocks will stress the upper control arm
rod ends and lower control arm spherical bearings.
Always verify track alignment. Proper track alignment is
critical when aligning the skis with the chassis.
Rod ends must be parallel with mating components. Rod
ends that are not parallel will increase the “bump steer”
effect.
An alignment bar is an essential tool required to set
camber.
Alignment Bar Specifications
• DIAMETER: .623”-.625” (15.824-15.875mm)
• LENGTH: 45” (114.3cm)
• MATERIAL: C-1018
• Polaris PN: 5333508 (Order from tool vendor.)
Maximum Setup Width
The maximum width setting is the distance between the
front center lines of both spindles with the skis off the
ground and the shocks installed.
Because of the design of the front suspension, maximum
width can only be changed by adjusting camber. This is
due to the fact that only the upper control arms feature rod
ends and thus camber can only be adjusted by turning the
upper control rod ends in or out.
1.
To measure the maximum setup width, raise the front
of the snowmobile off the ground with the shocks and
skis installed.
2.
Center the skis/spindles. Measure the distance
between the spindle center lines.
3.
If the measurement is out of specification, inspect the
front suspension for damage. Replace damaged
components.
4.
If no damage is found, reset the camber.
Handlebar Centering
1.
Raise the vehicle to remove the skis.
2.
Verify the handlebars are straight. Measure from each
bar end to a common center point at the rear of the
vehicle.
3.
Verify the steering drag link is not damaged, bent, or
loose. If it is, the drag link must be either adjusted or
replaced. If the drag link is correct, adjust the steering
linkage tie rod ends until handlebar is centered. Note
that the toe setting will require adjustment.
4.
Reinstall the spindle rod ends, bushings, and skis.
