Ski Wear Bars; Adjusting Ski Stance - Arctic Cat ZR4000 2016 Operator's Manual

Ski Wear Bars

The ski wear bar is a replaceable bar
attached to the underside of the ski. The pur-
pose 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. To maintain
positive steering characteristics, Arctic Cat
recommends that the ski wear bars be
checked before each use and replaced if
worn beyond 1/2 of the 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 Bars
1. Using Front End Lift (p/n 5639-

mobile.

Installing Ski Wear Bars


NOTE: If installing a double-offset
wear bar, the carbide edge should be
directed to the outside of the ski.

nuts. Tighten to 15 ft-lb.
