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 mini-
mal; 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, Yamaha recommends that the ski wear
bars be checked before each use and
replaced if worn beyond the wear limits
listed below. Ski wear bars are available
from an authorized Yamaha Snowmobile
dealer.
Removing
1. Elevate the front of the snowmobile.
2. Remove the lock nuts and washers
securing the wear bar to the ski.

3. Remove the wear bar from the ski.
! WARNING
Operating the snowmobile with exces-
sively worn ski wear bars may result
in a loss of steering control.
