Spindle Centering / Set Up Width - Polaris INDY TRAIL RMK Service Manual

Prior to performing steering alignment, the suspension should be inspected for damage or wear and replacement
parts installed as required. See inspection on page 6.6.
WARNING
A maximum set up width is listed in the chart on page 6.8. Maximum set up width is the maximum allowable dis-
tance 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 can come loose
and interfere with steering. Do not attempt to set the suspension wider than the specified Maximum Set Up
Width.

Spindle Centering / Set Up Width

1. 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.
2. Support the front of the machine 1-2² (2.5-5.1 cm) off the floor.
3. Remove skis and ski pivot bushings.
4. Disconnect adjustable torsion bar linkage where applicable.
5. Measure spindle to chassis centering as shown
and record measurement. Both spindles should be
an equal distance ±1/8² (3 mm) from the center of
the chassis after adjusting camber, width, and toe
alignment. This measurement is controlled by
adjusting radius rod length.
6. Measure set up width and record.
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.
This
Measure from center of one spindle to center of the
other spindle with front end elevated and suspension
fully extended to determine set up width.
