(b) It is also permitted a maximun step of 2.5 mm (0.0984 in.) out of the adjacent structure on 305 mm (12.0078 in.) (10%) of the gap lenght (MLG door forward edge).
(4) Adjust the uplock roller assembly as shown in view C if the step is greater than the maximun.
(a)
Open the MLG door (Ref. TASK 32-12-00-010-001).
(b)
Remove and discard the cotter pins (1).
(c)
Loosen the nuts (2).
(d)
Move the Uplock roller assembly mounting bracket (3) in the required direction.
1 To lower the door, move the Uplock mounting bracket up, or
_
2 To raise the door, move the Uplock mounting bracket down.
_
(e) TORQUE the nuts (2) to between 2.8 and 5.6 m.daN (20.64 and 41.29 lbf.ft).
(f) Safety the nuts (2) with a new cotter pin (1). Subtask 32-12-11-820-059
H. Adjustment of the Proximity Sensors
NOTE : Make sure that green hydraulic system is depressurized
____
(1)
Open the MLG doors to the fully open position (Ref. TASK 32-12-00-010-001).
(2)
Measure the gap X between the proximity sensors and the targets (Ref. Fig. 406/TASK 32-12-11-991-006) The correct gap should be 2.0 +0.5 -0.5 mm (0.0787 +0.0196 -0.0196 in.). If the gap is not correct, adjust on the proximity sensors.
(a)
Disconnect the electrical connector (3) from the applicable proximity sensor (4):
-
for System 1, LH, disconnect FIN 33GA
-
for System 1, RH, disconnect FIN 32GA
-
for System 2, LH, disconnect FIN 35GA
-
for System 2, RH, disconnect FIN 34GA.
(b)
Put a blanking cap on the disconnected electrical connector.

(c)
Remove the nuts (1), the washers (2) and the bolts (10).
(d)
Remove the proximity sensor (4).
(e)
Adjust the thickness of the peelable shims (11):
-
To increase the gap, remove the peelable shims (11) as required, or
-
To decrease the gap, add peelable shims (11) as required.
(f)
Put the proximity sensor (4) in position on the proximity sensor mounting bracket.
(g)
Install the bolts (10), the washers (2) and the nuts (1).
(h)
TORQUE the nuts (1) to between 0.125 and 0.192 m.daN (11.06 and
16.99 lbf.in).
(i)
Add SEALANTS (Material No. 09-004) to the bolts (10) and the nuts (1).
(j)
Remove the blanking cap from the electrical connector (3).
(k)
Make sure that the electrical connector (3) is in the correct condition.
(l)
Connect the electrical connector (3) to the applicable proximity sensor (4):
-
for System 1, LH, connect FIN 33GA
-
for System 1, RH, connect FIN 32GA
-
for System 2, LH, connect FIN 35GA
-
for System 2, RH, connect FIN 34GA.

J. Adjustment of the Targets
NOTE : Make sure that green hydraulic system is depressurized
____
(1) Measure the dimension Y between the center lines of the proximity sensors and the targets (Ref. Fig. 406/TASK 32-12-11-991-006) The correct dimensions should be to a maximum of 2.5 mm (0.0984 in.) either side of the center lines. If the dimension is not correct, adjust on the targets.
(a) Remove the nuts (8), the washers (9) and the bolts (5).

(b)
Remove the target (6).
(c)
Adjust the thickness of the peelable shims (7):
-
To move the target forward, add peelable shims (7) as required, or
-
To move the target rearward, remove the peelable shims (7) as required.
(d)
Put the target (6) in position on the target mounting bracket.
(e)
Install the bolts (5), the washers (9) and the nuts (8).
(f)
