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 characteris-
tics, Yamaha recommends that the ski
wear bars be checked once a week and
replaced if worn to 1/2 of original diame-
ter. Ski wear bars are available from an
authorized Yamaha Snowmobile dealer.
Removing
1. Raise the front of the snowmobile.
2. Remove the lock nuts securing the
wear bar to the ski.

3. Remove the wear bar.
Installing
1. Insert the wear bar studs into the
holes in the ski.
2. Center the wear bar studs in the
holes and install the lock nuts.
3. Tighten lock nuts securely.
Rail Wear Strips
Yamaha recommends that the wear strips
be checked weekly and replaced as nec-
essary.
