(3) Stage 2:
 (a)
 On the SENSOR-VOLTAGE TEST (F26792000) or SENSOR - VOLTAGE TEST

 (18) set the selector switch to U1.

 (b)
 Record the voltage (U1*).

 (c)
 On the SENSOR-VOLTAGE TEST (F26792000) or SENSOR - VOLTAGE TEST

 (18) set the selector switch to U2.

 (d)
 Record the voltage (U2*).

 (e)
 From the voltages U1* and U2*, calculate the voltage U*:
 U* = U1* - U2*

 (4)
 Stage 3:

 (a) Calculate the algebraic value T that has been introduced with the ADJUSTING TOOL - NWS GEARBOX (13) installed between the RVDT 3GC
 (16) and the N/WS gearbox (10):
 T = U - U*

 (5)
 Remove the RVDT 3GC (16) (Ref. TASK 32-51-19-000-001).

 (6)
 Carefully loosen the screws (11) through elongated holes of the ADJUSTING TOOL - NWS GEARBOX (13). Leave the ADJUSTING TOOL - NWS GEARBOX (13) installed.

 (7)
 Install the RVDT 3GC (16) (Ref. TASK 32-51-19-400-001).

 (8)
 Stage 4:

 (a)
 On the SENSOR-VOLTAGE TEST (F26792000) or SENSOR - VOLTAGE TEST (18), set the selector switch to U1 and then U2.

 (b)
 On the ADJUSTING TOOL - NWS GEARBOX, adjust the two knurled adjusters (14). (this will move the drive plate (12) of the gearbox (10)) until you get:

 U1 = U2 (plus or minus 10mV)
 This figure is the value U (reference)

 NOTE : When you turn the knurled adjusters, the gear box plate
____ (12) moves and changes the secondary voltages U1 and U2. When you turn the knurled adjuster:
 -
in one direction, U1 increases and U2 decreases,

 -
in the other direction, U2 increases and U1 dcreases.

 (9) Stage 5:
 (a)
 On the SENSOR-VOLTAGE TEST (F26792000) or SENSOR - VOLTAGE TEST (18), set the selector switch to U1.

 (b)
 Adjust the two knurled adjusters (14) again (this will compensate the value T put in with the installation of the ADJUSTING TOOL -NWS GEARBOX (13) until you get:

 U1 = U (reference) minus (T/2) (plus or minus 10mV) This figure is the value U (final)

 (10)
 Tighten the two knurled adjusters (14). Make sure that the position of the drive plate does not move.

 (11)
 Make sure that:

 U1 = U(Final)(plus or minus 10mV) If the value is not in the limits, do the procedure from stage 4 again.

 (12)
 Remove the RVDT 3GC (16) (Ref. TASK 32-51-19-000-001).

 (13)
 Tighten the screws (11) through elongated holes of the ADJUSTING TOOL

 -NWS GEARBOX (13).

 (14)
 TORQUE the screws (11)to between 0.1 and 0.15 m.daN (8.84 and 13.27 lbf.in)

 (15)
 Loosen the knurled adjusters (14).

 (16)
 Remove the ADJUSTING TOOL - NWS GEARBOX (13).

 (17)
 Install the RVDT 3GC (16) (Ref. TASK 32-51-19-400-001).

 (18)
 Do a check for the integrity of the adjustment:

 (a)
 On the SENSOR-VOLTAGE TEST (F26792000) or SENSOR - VOLTAGE TEST

 (18) set the selector switch to U1.

 (b)
 Record the voltage.

 (c)
 On the SENSOR-VOLTAGE TEST (F26792000) or SENSOR - VOLTAGE TEST

 (18) set the selector switch to U2.

 (d)
 Record the voltage.

 (e)
 Make sure that:

 U1 = U2 plus or minus 20mV. If the value is not in the limits, do the procedure from step (2) again.
 (19)
 On the panel 402VU, put the A/SKID & N/W STRG switch in OFF position.

 (20)
 Remove the SENSOR-VOLTAGE TEST (F26792000) or SENSOR - VOLTAGE TEST (18).

 (21)
 Connect the electrical connector (19) to the RVDT 3GC (16).

 (22)
 Do the procedure again for the RVDT 4GC (monitor channel).
