Ski Wear Bars
The ski wear bar is a replaceable bar
attached to the underside of the ski. The
purpose of the wear bar is to assist in
turning the snowmobile, to minimize ski
wear, and to maintain good steering con-
trol. If the snowmobile is operated pri-
marily in deep snow, ski wear bar wear
will be minimal; however, if the snow-
mobile is operated on terrain where the
snow cover is minimal, the ski wear bar
will wear faster. To maintain positive
steering characteristics, Arctic Cat rec-
ommends that the ski wear bars be
checked before each use and replaced if
worn beyond 1/2 of the original diameter.
Ski wear bars are available from an
authorized Arctic Cat Snowmobile
dealer.
Removing
1. Elevate the front of the snowmobile.
2. Remove the lock nuts securing the
wear bar to the ski.

3. Remove the wear bar from the ski.
Installing
1. Move the wear bar into position on
the bottom of the ski.
2. Align the wear bar studs with the
holes in the ski; then install the lock
nuts. Tighten to 15 ft-lb (20.4 N-m).
Adjusting Ski Stance
NOTE: Local laws and/or regula-
tions as to maximum width of the ski
stance on these snowmobiles may
be applicable. Always comply with
the maximum width laws and/or reg-
ulations when adjusting ski stance.
NOTE: On ZR/LT models, ski stance
can be increased/decreased by 2.5 cm
(1.0 in.). On M models, ski stance can
be increased/decreased by 2.0 in. (5
cm).
1. Place the front of the snowmobile on
a support stand.
2. Remove the cotter pin; then remove
the nut and cap screw securing the
ski assembly to the spindle. Remove
the ski. Account for the ski damper,
inserts, and washers.
3. To increase ski stance, place ski
stance spacers to the outside of the
spindle and adjust the ski damper.

4. To decrease ski stance, place ski
stance spacers to the inside of the
spindle and adjust the ski damper.
5. Apply a low-temperature grease to the
non-threaded portion of the cap
screw; then slide the cap screw
through the ski accounting for the ski
damper, inserts, and washers.
NOTE: Install the cap screw so the
nut will be located to the inside of
the ski.
! WARNING
Operating the snowmobile with
excessively worn ski wear bars may
result in a loss of steering control.
