Ski Wear Bars; Adjusting Ski Stance - Yamaha SR1NLK Operator's Manual

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.
! WARNING
Operating the snowmobile with exces-
sively worn ski wear bars may result
in a loss of steering control.
Removing (Dual)
1. Using Front End Lift, elevate the
front of the snowmobile.
2. Remove the lock nuts, washers, and
spacers securing the wear bars to the
ski.
3. Remove the wear bars from the ski.

NOTE: When the wear bars are
removed, measure the thickness of
both wear bars to see if they are
within the wear limit of 8.0 mm (0.31
in. (A and B). Replace as necessary.

NOTE: Measure the thickness of
the ski where the front and rear of
the wear bar contacts the ski to see
if it is within the wear limit of 13 mm
(0.51 in.) (A) and 8 mm (0.31 in.) (B).
Replace as necessary.
