NOTE:
A
new
actuator
may
be
installed
on
earlier
airplanes
as
a
spare.
The
new
actuator
may
be
identified
by
white
I
epoxy
paint
on
the
upper
actuator
arm
and the
upper
and
lower
actuator
housing.
When
the
new
actuator
is
installed
as
a
spare
on
earlier
airplanes,
the
actuator
should be
adjusted by using
the
5/8
to
3/4
hand crank
turns
remaining
after
the
motor
has
stopped.
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
1/8
to
114
turn
(5/8
to
3/4 turn
on
airplanes
using
new
white
actuators)
of the
emergency
hand crank and
adjust
the
switch
by
turning
the
screw
in
or
out
to
increase
or
decrease
travel
so
that
it
just
breaks
the circuit.
j.
Extend
gear
electrically
and check
with
the
hand
crank.
There
should
be
1/8
to
114
turn
(5/8
to
3/4
on
airplanes
using
the
new or
white
actuators)
between
the
extended
position
andthe internal
stop.
On
older models the
down
limit switch
is
adjusted
by
hand
forming
the
switch
actuator
arm
tab.
On
models with the
new
actuator
there
is
an
adjustment
screw on
the
switch.
Adjust
the
down
limit switch
so
that
it
just
breaks
the
circuit.
k.
Extend and
retract
the
gear
two
or
three times
to
assure
that the switches
are
correctly
set
and
the
dynamic
brake
is
operating
correctly.
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
(or
5/8 of
a
turn
with the
new or
white
actuators)
on
the hand crank
in
either the extended
or
retracted
positions.
i.
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
I
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.
m.
When
the
proper
setting
is
obtained,
leave the
gears
in the retracted
position
and
screw
the
up
stop
bolt down
against
the
main
strut.
To
assure a
firm
seating,
insert

Check
the
up
lock
roller
for
free
movement
and
a
clearance
of
0.010
to
0.020
in. between the roller and the
up
lock
block. If this clearance
is
not
correct,
the
up
lock
must be
adjusted.
To
adjust,
loosen the
block
retaining
I
bolts
and
adjust
the
clearance between
the roller and
the
up
lock block.
The
up
lock bracket
and
the block
are
serrated
and
the
serrations must
be
interlocked.
CAUTION:
The
up
lock cable
attach bolt
must
be installed with the head
pointing
aft
to
avoid
interference
with
the
stringer
in the
main
gear
wheel
well when
the
gear
is
fully
retracted.
o.
Extend the
gears
and
attach the
up
lock cable
to
the bracket.
p.
With
the main
landing
gear
fully
extended
and the down
lock in
the locked
position,
check the rollers for free
I
movement
and
a
clearance of 0.010
to
0.020
in, between
the
roller
and
the down
lock block.
If
this
clearance is
not
obtained,
loosen
the
block
retaining
bolts
and
adjust
to
proper
clearance.
Torque
the
bolts
to
90
to
100
in.-lbs.
Fully
retract
the
main
landing
gear
and
repeat
this
procedure
with the
up
lock in
the
locked
position.
q.
Fully
extend the
main
landing
gear
and
with the down
lock
in
the
locked
position,
check for
a
clearance of
0.03
to
0.10
in,
between
the
inboard
ends
of the down
lock
spring
and the down lock
at
the
point
of
juncture
where
the
down lock
attaches
to
the
strut.
Add
or remove
washers
(Pn\l

as
necessary
to
obtain this
clearance.
