SERVICE
MANUAL
CAUTION
Do
not
exceed
these
tube
exposures.
These
measurements
are
taken
with
the
airplane
sitting
on
level
surface
under
normal
static
load.
(Empty
weight
of
airplane
plus
full
fuel
and
oil.)
If
the
strut
has
less
tube
exposure
than
prescribed,
determine
whether
it
needs
air
or
oil
by
rocking
the
airplane.
If
the
oleo
strut
oscillated
with
short
strokes
(approximately
one
inch)
and
the
airplane
settles
to
its
normal
position
within
one
or
two
cycles
after
the
rocking
force
is
removed,
the
oleo
strut
requires
inflating.
Check
the
valve
core
and
filler
plug
for
air
leaks,
correct
if
required,
and
add
air
as
described
in
Paragraph
2-36.
NOTE
Valves
should
be
installed
with
a
torque
of
45
ft.
lbs.
The
valve
caps
with
bare
threads
should
also
be
torqued
to
45
ft.
Ibs.
while
caps
with
phosphate
coating
torqued
to
22.5
ft.
lbs.
If
the
oleo
oscillates
with
long
strokes
(approximately
three
inches)
and
the
airplane
continues
to
oscillate
after
the
rocking
force
is
removed,
the
oleo
struts
require
fluid.
Check
the
oleo
for
indications
of
oil
leaks,
correct
if
required
and
add
fluid
as
described
in
Paragraphs
2-34,
2-35
or
2-35a.
For
repair
procedures
of
the
landing
gear
and/or
oleo
struts,
refer
to
Section
VI
or
VIA.
WARNING
Do
not
release
air
by
removing
the
strut
valve
core
or
filler
plug.
Depress
the
valve
core
pin
until
strut
chamber
pressure
has
diminished.
CAUTION
Dirt
and
foreign
particles
form
around
the
filler
plugs
of
the
landing
gear
struts,
therefore,
before
attempting
to
remove
these
plugs,
the
tops
of
the
struts
should
be
cleaned
with
compressed
air
and/or
with
a
dry
solvent.

whether
it be
only
the
addition
of
a
small
amount
or
if
the
unit
has
been
completely
emptied
and
will
require
a
large
amount,
it
should
be
filled
as
follows:
a.

the
airplane
on
jacks
until
the
