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 control. If the snowmobile
is operated primarily in deep snow, ski wear bar wear
will be minimal; however, if the snowmobile is operated
on terrain where the snow cover is minimal, the ski wear
bar will wear faster. Arctic Cat recommends that the ski
wear bars be checked once a week and replaced if worn
to 1/2 of original diameter.

REMOVING
1. Using a suitable stand or lift, raise the front of the
snowmobile off the floor; then remove the lock
nuts securing the wear bar to the ski.
2. Pry the rear of the wear bar down until 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.
3. Remove the wear bar.
INSTALLING
1. Insert the front of the wear bar into the hole at the
front of the ski and swing the wear bar upward;
then insert the wear bar studs into the holes in the
ski.
DO NOT bend the ski wear bar excessively when
installing. Excessive bending of the ski wear bar may
cause premature wear, breakage, and possible injury.

the lock nuts. Tighten lock nuts securely.
