5.
Reinstall the
bolt
attaching
the
uplock
roller
at
the
center
hinge
point
of
the

Check
the
uplock
roller
for
free
movement
and
a
maximum clearance of
0.010 to
0.020
inch
between
the

The
uplock
roller
bearings
should
be
lubricated
with
grease
(11,
Chart
3)
every
100
hours
or
any
time that
while
I
cleaning
the wheel
well,
the
bearings
are
subjected
to
degreasing
with
solvent
under
pressure.
The
uplock
bearing
is lubricated
by
means
of
a
grease
fitting
installed
in
the
uplock
bearing
bolt.
NOTE:
The
grease
fitting
on
the
drag leg,
directly
above the
uplock
roller
does
not
supply
lubricant
for
the
uplock
roller
bearing.
SHOCK
STRUTS
The
shock
struts
are
filled
with
compressed
air
and
hydraulic
fluid
(13,
Chart
3).
The
same
procedure
Is
used
for
servicing
both
the
main and
nose
gear
shock
struts.
To
service
a
strut
proceed
as
follows:
a.
Remove
the
air valve
cap
and
depress
the
valve
core
to
release
the air
pressure.
WARNING: Do
not
unscrew
the air
valve
assembly
until
the air
pressure
has
been
released
or
tt
may
be
blown
off
with
considerable
force,
causing injury
or
property
damage.
b.
With the
weight
of
the
airplane
on
the
gear,
loosen the air valve
assembly
slowly
to
ensure
that
all air has
escaped,
then
remove
the air valve
assembly.
c.
With the
shock
strut
fully
deflated,
jack
the
strut
barrel
1/4-inch
off
fully
compressed,
block
it
there
and
fill
to
the
level
of
the air valve
assembly
hole
with
hydraulic
fluid
(13,
Chart
3).
d.
Jack
the
main
strut
an
additional
2
inches,
then
replace
the air
valve
assembly,
depress
the
valve
core
and lower
the
jack,
releasing
the
excess
air
and oil.
On
the
nose
strut,
merely
remove
the block
and
allow
the
excess
oil
to
drain
away,
then
install the
air valve
assembly.
e.
Rocking
the
airplane
gently
to
prevent
possible
binding
of
the
piston
in the
barrel,
inflate the
nose
gear
strut
and
main
gear
strut
until
they
reach the
dimensions
which
are
specified
in
General
Information,
Section 1
(airplane
resting
on
the
ground).
NOTE:
It is
recommended that the
nose
and
main
strut
inflation
dimension
and
recommended
tire
pressure
be
adhered
to.
Properly
inflated tires
and shock
struts
reduce the
possibility
of
ground
damage
occurring
to
propellers;
however,
exercise
caution when
taxiing
over
rough
surfaces.
f.
The
shock
strut
pistons
must
be clean.
Remove
foreign
material
by
wiping
the
strut
with
a
cloth
containing
hydraulic
fluid.
