(a)
On the SENSOR-VOLTAGE TEST (F26792000) or SENSOR - VOLTAGE TEST set the selector switch to U1.
(b)
Manually move the wheels in steering mode on the RH stop. Record the voltage U1.
(c)
Manually move the wheels in steering mode on the LH stop. Record the voltage U1'.
(d)
From the voltage U1 and U1', calculate the average voltage U1".
(e)
Manually move the wheels in steering mode to get the voltage U1". NOTE : The angular travel of the nose wheels includes the NLG cam

B. Set the NWS Zero Position CAUTION : IF THE SENSOR BOX HAS P/N E21336000, NEVER REMOVE THE SENSOR
_______ FROM THE GEARBOX. THE SENSOR AND THE GEARBOX ARE AN ASSEMBLY THAT YOU MUST NOT DISASSEMBLE ON THE AIRCRAFT. IF YOU REMOVE THE SENSOR FROM THE GEARBOX:
-YOU WILL CAUSE DAMAGE TO THE SENSOR BOX
-THE ADJUSTMENT OF THE SENSOR BOX WILL NO LONGER BE CORRECT. NOTE : When the shock absorber is fully extended, the NLG is
____ automatically in the center position (the nose wheel steering is in the zero position).
NOTE : Do not move the wheels manually in the steering mode when you do
____
the adjustment procedure.
(1)
Measure the secondary voltages U1 and U2 for the sensor 3GC
Make sure that :
U1 = U2 plus or minus 20 mV
(2)
If U1 is not equal to U2 plus or minus 20 mV, do these steps:
(a) Use a spatula to remove the sealant:
-
from the areas identified S.
-
from the housing of the worm screw (5).

____
parts.
(b)
Loosen the screws (2) to release the sensor.
(c)
Turn the worm screw (5) to get: U1 = U2 plus or minus 20 mV
(d)
TORQUE the screws (2) to between 0.29 and 0.35 m.daN (25.66 and
30.97 lbf.in).
(e)
Make sure that U1 = U2 plus or minus 20 mV. If not, do the adjustment again.
(3)
On the panel 402VU, set the A/SKID & N/W STRG switch to OFF.
(4)
Remove the SENSOR-VOLTAGE TEST (F26792000) or SENSOR - VOLTAGE TEST (F26792000-1) (3).
(5)
Connect the electrical connector (4) to the sensor box (1).
(6)
Apply a layer of SEALANTS (Material No. 09-008E) on the areas identified S.
(7)
Fill the housing of the worm screw (5) with SEALANTS (Material No. 09-008E).
(8)
Do the adjustment procedure again for the sensor 4GC (monitor channel).
(9) On the panel 402VU, set the A/SKID & N/W STRG switch to ON. Subtask 32-51-00-865-097
