MANUAL
I
All
landing
gear
operations,
tests
and
adjustments
are
to
be made
with
a
regulated voltage
source
of
28.25
0.25vdc
under
load.
a.
Lengthen
the
main
and
nose
gear
retract
rods
sufficiently
to
eliminate
the
danger
of
the
V brace
on
the main
gear
damaging
the skin when
the
gear
is retracted
and excessive tensions
an
the
nose
gear
retract
rods.
Damage
to
vital
parts
may
result
if abnormal
loads
are
applied
to
the
retract
system.
By
lengthening
the
retract
rod,
such
danger
is
removed.
Disconnect
up
lock cables
at
the
brackets,
leaving
the
springs
attached.
If
the
springs
are
disconnected,
upon
the retraction
of the
gear
the
up
lock
arm
may
damage
the
top
wing
skin. Place
the
up
lock
block in the lower
position.
b.
Disconnect
the
nose
wheel
door
linkage
at
the
attaching
point
on
the door
and
remove
links
by unscrewing
at
the
upper
ball
joint.
c.
Remove
bolts
attaching
the main
gear
outboard door links
to
main
strut.
Remove
inboard
door
actuator
rod
by
unscrewing
from inboard rod
ends
and
removing
bolt in door bracket.
d.
Screw
stop
bolts in
(V
brace
assembly,
main
gear)
until
approximately
four
or
five
threads
are
showing.
CAUTION:
When
running
the
gear
electrically
before
the
switches
are
reset
or
for the
first
time
after
resetting
the
switches,
run
it with
extreme
caution
to
make
sure
the
switches
open
the electrical
circuits
before
the
sector
gear
hits the
internal
stops
in the
gear
box.
The
sector
gear
should
not
be
touching
the
stop
when
the
motor
stops
coasting.
Serious
damage
may
result
if
the internal
stops
are
hit
by
the
sector
gear.
NOTE:
To
operate
the
landing
gear
control
circuit
breaker
as a
momentary
switch,
push
it
in
for
operating
the
gear
and
pull
it
out
for
stopping
the
operation.
Leave the breaker
pushed
in
only long enough
for
the
gear
to
make
the desired distance
of travel.
e.
Using
the
landing
gear
control
circuit
breaker
as a
momentary
switch,
run
the
gear
about
2/3
up.
Inch
the
gear
the
remaining
distance
to
the
limit
switch
by
the
momentary
operation
ofthe circuit breaker.
Check
the hand
crank for
3/8
to
1/2
turn
between
retracted
position
and the
internal
stop
for
preliminary settings.
If
this
clearance
is
not
obtained
adjust
the
landing
gear up
limit
switch.
The
limit switches
are
located
adjacent
to
the
landing
gear
actuator
assembly
under
the
pilot’s
seat.
To
adjust
the
up
limit
switch,
lower the
landing
gear
118
to
114
turn
of
the
emergency
hand crank
and
adjust
the
switch
by
tuming
the
screw
in
the
actuator
so
that
it
just
breaks the
circuit.
This is
to
prevent
the
sector
gear
from
hitting
the internal
stops.
f. Extend
gear
electrically
and
check with the hand
crank.
There should be 1/8
to
1/4
turn
between
the
extended
position
and the internal
stop.
The down
limit switch
adjustment
is
accomplished
by bending
the
switch
actuator
arm
tab
so
that
it
just
breaks
the
circuit.
g.
Extend
and
retract
the
gear
two
or
three times
to
assure
that
the
switches
are
correctly
set.
Check
the
hand
crank each
time
to
ensure
proper
adjustment.
NOTE:
It
may
be
necessary
to
make
a
closer
setting
of the limit
switches,
but there
should
never
be less than 1/8
of
a
turn
on
the hand
crank
in
either the
extended
or
retracted
positions.
h.
Adjust
the
main
retract
rod
(either
right
or
left)
to
maintain
1/16
in.
minimum clearance
between the
joint
(knee)
of
the
V brace and
lift
leg
and the
top
wing
skin with the
landing
gear
fully
retracted.
The main
gear
should
retract
only
far
enough
to
clear
the
inboard
door
in
addition
to
maintaining
the minimum
of
1/16
in,
clearance.
To
decrease
the clearance
between
the knee
and the
top
wing
skin,
shorten the
retract
rod;
to
increase
clearance,
lengthen
the
retract
rod.
i.
When the
proper
setting
is
obtained,
leave
the
gears
in
the retracted
position
and
screw
the
stop
bolt
down
against
the main
strut.
To
assure
a
firm
seating,
insert
a
0.003
feeler
gage
under the
bolt
head
and
adjust
the
bolt
until
a
firm,
steady
effort
is
required
to
pull
the
feeler
gage
out.
With the
feeler
gage
removed,
screw
the bolt
down
an
additional
314
turn.
Tighten
locknut
securely.
