Tightness of.the steering
column
to the
ski
linkage syst
em
is
very important in
controlling
parallelism
of
the
skis while
the snowmobile is
in
motion.
Skis
are
supported on
two
5
leaf springs that are pivoted at the rear
of
tl1e
ski and
free
to expand and contract by being
set
in
a
wear
plate
at
the
front part of the ski. This wear plate should be
greased
often to reduce friction on the
spring and
wear
plate.
9-9-2
Parallelism of the skis is
checked
by measuring
from center
to center (outside of one
ski
to inside
of other ski)
.
Adjustment of parallelism is accomplished by
adjust
ing
the
tie rod length. Correct center to center
distance of
tl1e
skis
is
24.1'' (613
mm).
