Installation of
Up
Lock Roller
Lubricating
I
Bolt
Assembly.
j.
Check
the
up
lock
roller
for free
movement
and
a
maximum 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
bolts and
adjust
the
clearance
between
the roller and
the
up
lock
block. The
up
lock bracket
and
the
block
are
serrated
and the serration
must
be interlocked with each other.
NOTE:
The
up
lock cable
attach
bolt
must
be installed with
the
head
pointing
ah
to
avoid interference with
stringer
in
the
main
gear
wheel
well
when the
gear
is
fully
retracted.
k.
Extend
gears
and
attach the
up
lock
cable
to
bracket.
i.
Retract
the
gears
intermittently
as
in
Step
e.
above,
and observe
the
locking
action
of the
up
lock
bracket.
If
it
starts
to
lock
too
soon
it
is
an
indication
that the
up
lock
cable is
too
tight.
The
cable should
be
adjusted
for
a
tension
of
52.5
+10 0
Ibs.
The
tension
is
adjusted
at
the outboard
end
of the
cable.
If
sufficient
adjustment
is
not
obtainable
at
the
cable
eye,
additional
adjustment
may
be
made
at
No.
3
wing
rib
by
moving
the
cable
housing
inboard
or
outboard.
m.
Extend the
main
gear
and
check the force
required
to
deflect the
main
gear
knee
joint.
With
the
gears
in
down
position,
it
should
take
45
to
65
Ibs of force
to
deflect the main
gear
knee
joint.
To
increase
tension,
add
I
100951S063XP
washers
between the
spring
and
rod
end.
A maximum
of
five
washers
may
be
added.
If
more
tension
is
needed,
replace
the
spring.
NOTE:
If
unable
to
obtain
adequate spring
tension,
check
for
worn
bushings
in the
retract
linkage.
Wear
in
the
bushings
has
the
effect of
lengthening
the entire
linkage,
causing
the rod
end
spring
to
compress
and
stack,
leaving
nothing
for
spring
adjustments.
New
bushings
will shorten
the
linkage, again permitting
adjustment
of the
spring.
n.
With the
gear’s
extended
in the
full
down
position
and
the
wheel
clearing
the
floor,
adjust
the
nose
gear
tension
at
the aft
retract
rod
(shorten
or
lengthen)
to
obtain
deflection force
of
55
Ibs
or
higher (providing
the
retract
spring
does
not
stack
at
any
point
during
the
full
travel
of
the
nose
gear)
at
the
union
of
the
V
brace
assembly
and
the
drag
leg
assembly.
The
deflection force
should
be
applied
at
the
pivot point
of this
union
in
a
plane
perpendicular
to
the
center
line
between
these assemblies.
To
obtain
the
above
requirements,
additional
100951DD032XM
andlor 100951DD064XM washers
may
be
required
at
the
forward end of
the
retract
rod
spring.
With the
nose
wheel in
fully
retracted
position
(strut
against
bumper
on
V
brace)
and
with doors
disconnected,
a
force
of
30
to
35
Ibs
applied
downward
at
the
center
line
of
the
tow
pin
shall be
required
to
move
1
the
strut
off
the
bumper.
With
the
nose
gear
in full retracted
position
and
both doors
fully
rigged,
a
force of
20
Ibs
minimum
applied
downward
at center
line
of
tow
pin
shall
be
required
to
move
the
strut
0.12
in.,
measured
along
the
line of force
application.
o.
Unscrew
main
gear
outboard
door
attaching
link
to
assure
the door is
not
damaged
when
retracted. Connect
outboard
door
linkage
and
retract
gear
slowly, checking
to
see
that clearance is maintained
between
the
door
and
gear.
After
checking
to
see
that
the door is
nottoo
tight,
run
gear
down
and
adjust
linkage
as
required,
continue
this
procedure
until
a
snug,
firm fit is
obtained
when the
door is
completely
closed.

slowly
and
check
for
clearance
between

linkage
and

Continue
this
procedure
until
