Camber Definition - All IFS

The following definitions of camber use automotive
terminology to describe positive and negative posi-
tions. Refer to the illustration at right.

0 (Neutral) Camber - Spindle is 90



(perpendicu-

lar) to ground

+ (Positive) Camber - Spindle bottom is canted
inward toward chassis

-- (Negative) Camber - Spindle bottom is canted

outward from chassis

Radius Rod and Tie Rod End Torque Procedure

Radius rod and tie rod ends must be parallel to their
respective mounting surface after tightening jam nut
as shown at right. Hold tie rod or radius rod and tigh-
ten jam nut. If possible, support the edge of the rod
end as shown to keep it from rotating out of position
until jam nut is tight. When tie rod ends are properly
tightened, the tie rod should rotate freely approxi-
mately 1/8 turn.

2001 IFS Steering Alignment Specifications

The following information is to be used for 2001 Polaris Snowmobile front suspension setup.
The data in the following table is based on the 2001 Polaris factory settings. Maximum Width
and Camber measurements are to be taken with the front end elevated and shocks at
full extension. Toe alignment is measured at ride height.

WIDTH NOTE: Width is measured in inches from the center of the spindles near the grease fitting for the ski
mount bolt located at the base of the spindle. The tolerance on this measurement is

1/4

〉

TOE ADJUSTMENT NOTE: Toe is measured in inches with the machine on the ground and resting at normal
ride height - not full rebound. Measure at a point 10

〉

(254mm) forward of the ski mount bolt and 10

〉

behind the

ski mount bolt, preferably on the centerline of carbide skags. Note: Measurements to points on the skis may be
inaccurate. See page 6.20.

NOTE: Camber measurement is taken in inches from top of alignment bar to the top of ski mount hole in the
spindle (bushing removed). See Page 6.18

STEERING / FRONT SUSPENSION

6.16

Prior to performing steering alignment, the suspension should be inspected for damage or wear and replacement
parts installed as required. See inspection on page 6.13.

WARNING

A maximum set up width is listed in the chart on page 6.15. Maximum set up width is the maximum allowable
distance between ski spindle centers with front end of vehicle off the ground and suspension fully extended. The
Maximum Set Up Width specifications are maximum width measurements, and are critical to ensure adequate
torsion bar engagement with the trailing arm. If the suspension is set too wide , the torsion bar may disengage
from trailing arm. Do not attempt to set the suspension wider than the specified Maximum Set Up Width.

Spindle Centering / Set Up Width / Camber Adjustment

Make sure the track is properly aligned. Refer to Maintenance Chapter for procedure. This will be used as a
reference point for final toe out measurement.

Support the front of the machine 1-2

〉

(2.5-5.1 cm) with the skis off the floor.

Remove skis and ski pivot bushings.

Disconnect adjustable torsion bar linkage where applicable.

Measure spindle to chassis centering as shown
and record measurement. Both spindles should be
an equal distance +/- 1/8

〉

(3 mm) from the center of

the chassis after adjusting camber, width. This
measurement is controlled by adjusting radius rod
length.

and

record.

This

measurement is controlled by adjusting radius rod
length, and must not exceed the Maximum Setup
Width listed in the appropriate table (at the front of
this section) after all steering adjustments are
complete. See illustration below for procedure.
NOTE: Camber / Width / and Centering are
dimentions that depend on each other. Each one
should be checked after any changes made.

Make marks here at the center of the contact
area. Measure from mark to mark

Measure the center to centerof the spindles with the front

end elevated and suspension fully extended to determine

set up width. Using a straight edge scribe a mark in the

center of the spindle. As close to the base of the spindle

tube as possible

Camber Adjustment

Determine which spindle requires the greatest
amount of correction by installing the alignment
bar through one side to the opposite spindle.
Remove the bar and install it through the other
side to the opposite spindle. Measure from the
top of the bar to the top of the hole. Turn the upper
and lower radius rods (like a turn buckle) to
achieve the approperate camber width.
NOTE: Camber / Width / and Centering are
dimentions that depend on each other. Each one
should be checked after any changes.

extension, loosen the radius rod end jam nut.
Remove the lower radius rod bolt from the spindle
requiring the most camber correction. Adjust the
opposite side next.

To adjust camber, change lower radius rod length
until alignment bar measurement is within
specified range for each spindle. Refer to charts
on page 6.15 for camber specifications.

models with neutral camber (0) the bar should
slide freely through both spindles (

tolerance).

CAUTION:

Radius rod ends must remain parallel to the bulkhead
after rod end jam nuts are tightened to specified
torque. See illustration at right.

Tighten all jam nuts. Torque radius rod attaching
bolts to specification.

WARNING

After camber adjustment is complete, be sure to measure set up width outlined on page 6.16 and compare to speci-
fications. Do not attempt to set suspension wider than the specified maximum set up width. If set up width exceeds
maximum, adjust upper and lower radius rods equally to maintain camber adjustment.
