Adjusting Suspension
(Cheetah)
~
~
The suspension should be adjusted for the operator
and
normal
average
load.
The rear springs should
be adjusted for the we ight and riding preference of
the operator. The
optimum
adjustment on
the rear
springs prevents the suspens ion
from "bottoming
out"
on
all
but
the
most
severe bumps. The
springs should
not
be adjusted so stiffly that the
suspension
will
not
work
properly under
normal
conditions.
A
good
test
of
a
properly
adjusted
suspens
ion
is
the operator
shou
ld
just be ab le
to
"bottom" the suspens
ion
when
jumping
up
and
down on the rearmost
part of the running
board.
The
front
spring
adjustment primarily influences
the way the snowmobile performs in
snow and
the
effort
requi
red
to
stee
r
the
snowmob
ile.
The
op-
t
imum setting
for
t
he front
sprin
g
(when
spri
ng
tension
is
suffic
iently st
iff to prevent
the suspen-
sion
from
co
ll
apsing in
deep snow but
not so stiff
that
steering becomes ineffective)
is
when 12
mm
(%
in.) of thread is apparent behind
each
lock nut.
FRONT SPRING
To
adjust
spring
tension,
t ighten or loosen the
lock nut on the eyebo lt connected
to the spring
unti
l
desired
tension
is
atta ined.
Perform this procedure on both
sides
to maintain
equa
l
adjustment on both
springs.
