Ski Wear Bar

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 once a week and replaced if
worn to 1/2 of original diameter. Ski
wear bars are available from an autho-
rized Arctic Cat Snowmobile dealer.
! WARNING
Operating the
excessively worn ski wear bars may
result in a loss of steering control.
Removing Ski Wear Bar
1. Remove ice and snow buildup from
the ski.
2. With the gas tank nearly empty (less
than 1/4 full), lay the snowmobile on
its side. A piece of cardboard should
be used to protect the finish on the
hood and belly pan.
3. Remove the lock nuts securing the
wear bar to the ski.
4. Pry the rear of the wear bar down
until both of the wear bar studs are
clear of the ski; then slide the wear
bar rearward until the front of the
wear bar is free from the ski.
5. Remove the wear bar.

the hole at the front of the ski and

DO NOT bend the ski wear bar exces-
sively when installing. Excessive
bending of the ski wear bar may
cause premature wear, breakage,
and possible injury.
2. Insert the wear bar studs into the
holes in the ski.
3. Center the wear bar studs in the
holes and install the lock nuts.
4. Tighten lock nuts securely.
Recoil Starter Air
Vents
It is important for proper engine cooling
that the air vents located on the recoil
starter are kept clean. These air vents
should be checked periodically and
cleaned if necessary.
CAUTION
Serious overheating of the engine
and engine damage will result if the
air vents are not kept clean.
