MAINTENANCE
4. Remove the wear bar from the
ski and account for the location
of the bushings (if applicable).
Installing Ski Wear Bars
1. If applicable, place the bushings
onto the studs; then move the
wear bar into position on the
bottom of the ski.
NOTE: If installing a double-off-
set 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 washers (if applicable) and
lock nuts. Tighten to 1.5-2.1 kg-
m (11-15 ft-lb).
ADJUSTING SKI STANCE
(M-Series/King Cat/Bearcat 570
Models)
1. Place the front of the snowmo-
bile on a support stand.
2. Remove the cotter pin; then
remove the slotted nut and cap
screw securing the ski assembly
to the spindle. Remove the ski.
Account for the rubber damper,
inserts, and washers.
3. To increase ski stance 2.5 cm (1
in.), place both ski stance spac-
ers to the outside of the spindle.
4. To decrease ski stance 2.5 cm (1
in.), place both ski stance spacers
to the inside of the spindle.
5. Position the ski over the saddle.
6. Apply a low-temperature grease
to the non-threaded portion of
the cap screw; then slide the cap
screw through the ski and sad-
dle accounting for the rubber
damper, inserts, and washers.
NOTE: Install the cap screw so
the slotted nut will be located to
the inside of the ski.
7. Apply red Loctite #271 to the
threads of the cap screw; then
tighten the nut to 6.2 kg-m (45
ft-lb).
8. Place the cotter pin into the ski
cap screw and spread the pin.
9. 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.) inter-
vals. Wear strips must be 10.7 mm
(0.42 in.) thick or thicker. If wear
strip measurements are less than
specified, replacement of both wear
strips is necessary to prevent prema-
ture track clip wear and possible
track damage. Take the snowmobile
to an authorized Arctic Cat Snow-
mobile dealer for this service. This
service is at the discretion and
expense of the snowmobile owner.
Each time a new set of wear strips
are installed, they should be tem-
pered. Temper the wear strips by
driving the snowmobile for approxi-
mately a mile on a hard pack trail;
then immediately drive into deep
snow and allow the wear strips to
cool. Repeat the procedure (warm-
ing up the wear strips; then cooling
them down) two or three times.
NOTE: The rail wear strips will
wear rapidly if the snowmobile is
operated on terrain on which the
snow cover is minimal. Loose
snow is required to cool and
lubricate the wear strips and pre-
vent accelerated wear.
