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 turn-
ing the snowmobile, to minimize ski wear,
and to maintain good steering control. If
the snowmobile is operated primarily in
deep snow, ski wear bar wear will be min-
imal; however, if the snowmobile is oper-
ated on terrain where the snow cover is
minimal, the ski wear bar will wear faster.
To maintain positive steering characteris-
tics, Arctic Cat recommends that the ski
wear bars be checked before each use and
replaced if worn beyond 1/2 of the origi-
nal diameter. Ski wear bars are available
from an authorized Arctic Cat Snowmo-
bile dealer.
Removing Ski Wear Bars
NOTE: Determine which type of
wear bar is being replaced and
remove and install accordingly.
1. Remove ice and snow buildup from
the ski.
2. Using a suitable safety stand or lift,
elevate the front of the snowmobile.
3. Remove the lock nuts securing the
wear bar to the ski.
0743-185
4. Remove the wear bar from the ski.
Installing Ski Wear Bars
1. Move the wear bar into position on
the bottom of the ski.
NOTE: If installing a double-offset
wear bar, the carbide edge must be
directed to the outside of the ski.
2. Align the wear bar studs with the
holes in the ski; then install the lock
nuts. Tighten to 11-15 ft-lb.
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: Ski stance can be increased/
decreased by 2.5 cm (1.0 in.).
1. Place the front of the snowmobile on
a support stand.
2. Remove the cotter pin; then remove
the slotted nut and cap screw secur-
ing the ski assembly to the spindle.
Remove the ski. Account for the
rubber damper, inserts, and washers.
3. To increase ski stance, place both ski
stance spacers to the outside of the
spindle.
4. To decrease ski stance, place both
ski stance spacers to the inside of the
spindle.
5. Apply an all-temperature grease to the
non-threaded portion of the cap
screw; then slide the cap screw
through the ski accounting for the rub-
ber damper, inserts, and washers.
NOTE: Install the cap screw so the
slotted nut will be located to the
inside of the ski.
6. Apply red Loctite #271 to the
threads of the cap screw; then
tighten the nut to 45 ft-lb.
7. Place the cotter pin into the ski cap
screw and spread the pin.
8. Repeat procedure for the other ski.
Rail Wear Strips
Arctic Cat recommends that the wear
strips be checked weekly and replaced as
necessary. Measure the wear strips at 25.4
cm (10 in.) intervals. Wear strips must be
10.7 mm (0.42 in.) thick or thicker.
! WARNING
Operating the snowmobile with
excessively worn ski wear bars may
result in a loss of steering control.
