LANDING
GEAR SERVICE
The three landing
gears use Cleveland
Aircraft
Producrs 6.00
x
6, four-ply
raring, rype
III
rires
and
tubes. (Refer
ro paragraph 8.23.)
Wheels are removed
by taking off
the hub cap, cotter pin, axle nut,
ancl
the two bolts holding
the
brake.segment
in
place. Mark tire
and wheel for reinstallition;
then dismount by deflating rhe tire,
removing the three through-bolts from the wheel and separating the wheel halves.
Landing gear oleos on the Cherokee Archer
II
should be serviced according
to the instruoions on
the
units. The main oleos should be
extended under normal static load
until
4.50
i
.50
inch_es
of
oleo piston
tube
is
exposed, and the nose gear should show 3.25
+
.2-5
inches. Should the strur exposure be below that
required,
it
should be cletermined whether
air or oil
is required by first
raising the airplane
on
jacks.
Depress
the valve core to
allow air to
escape
from
the strut housing
cham'ber. Remove-the
filler
plug
aid
slowly
raise
the strut to
full
compression.
If
the strut has sufficient fluid, it will
be visible up to the bottorn
of
the
filler
plug hole
ancl
will thln
require only proper inflation.
Should
fluid
be below the bottom of
the
filler
plug hole,
oil
should be added. Replace the plug with
valve core removed;-attach a clear plastic hose to the valve stem
of
the
filler
plug ancliubmerge the'other
end
in
a container
of hydraulic fluid. Fully
compress and extend rhe strut seveial
ti-.r,
thus
d[wing
fluid
front the container
and
expelling air from the stiut
charnber. To allow
fluid
to enter the bottom
chamlber
of
the main
gear strut housing, the torque link
assembly must be disconnected to let the strut
be exrended
a
minimum
of
10 inches (the nose gear torque
links
need
not be
disconnectecl).
Do not allow the strut
to
extend more than
l2
inches. When air
bubbles
cease
to flow through the
hose, compress the strut
fully
and
again check
fluid
level. Rernstall the valve core
ancl
filler
plug, antl the main
gear torque links,
if
disconnected.
With fluid in
the strut housing at the correct level, attach a strut pump
to the air valve
and
with
the
airplane on
the
ground, inflate the oleo strut to
the
correct height.
In jacking the aircraft
for
landing geal or other service, two hydraulic jacks and a
tail
stand should
be
usecl.
At
least
2-50
pounds
of
ballast should be placed on the
base
of
the
tail
stand before the airplane
is
jacked up. The hydraulic jacks should be placed under the
jack
points on the bottom
of
the wing
ind
the
airplane
jacked up
until
the
tail
skid is at the right .height
to
atrach
the
tail
stand.
After the taii
stand
is
attached and the
ballast
added,
jackrng may
be
continued until
the airplane is
at the height desired.
T'he
steering arnts from the
ruclder pedals
to the
nose wheel are adjusted at the nose wheel by turning
the threaded rod end bearings in
or out. Adjustment is normally
accomplished at the forward end of
the
rods and should be done
in
such a way that the nose wheel is in line with the fore
and
aft axis of the
plane
when the rudder pedals and rudder are centered. Alignment
of
the nose wheel can be checked by
pushing
the airplane back and forth with
the rudder
centered
to
determine that the plane follows a
perfectly
straight line. The turning arc of
the nose wheel
is 30.0' +
2o
in
either direction and
is limited by
stops
on
the
bottom of the torging.
The rudder pedal arm stops shoulcl be carefully
ad.iusted
so that the pedal arms contact the
stops
just
after the rudder hits
its
stops.
This
guarantees
that the rudder
will
be allowed
to
move through
its full
travel.
