Hold the rigging tool M46196-2 (14) in position and loosen the screws (12).
(14)
Lightly move the gearbox plate (11) with the rigging tool M46196-2 (14):.
-clockwise if the value C is positive
-counterclochwise if the value C is negative
(15)
TORQUE the screws (12) to between 0.1 and 0.15 m.daN (8.84 and 13.27 lbf.in).
NOTE : Make sure that the gearbox plate (11) does not move when you
____ TORQUE the screws (12). If the gearbox plate (11) moves, the adjustment will not be correct.

Install the RVDT 3GC (1) (Ref. TASK 32-51-19-400-001). NOTE : Lightly lubricate the packing of the sensor 3GC with COMMON
____
GREASE (Material No. 04-015).

Stage 7:
(a)
On the SENSOR-VOLTAGE TEST (F26792000) or SENSOR - VOLTAGE TEST
(2) set the selector switch to U1.
(b)
Record the voltage (U1)(in AC voltage).
(c)
SENSOR-VOLTAGE TEST (F26792000) or On the SENSOR - VOLTAGE TEST
(2) set the selector switch to U2.
(d)
Record the voltage (U2)(in AC voltage).
(e)
Calculate the algebraic value D:
(U1 - U2) = D
(20)
Stage 8:
Check that the algebraic value D:
D = C +/- 20 mV
(a)
If the value D is less than the value C plus or minus 20 mV, adjust the gearbox again and move the gearbox plate (11) clockwise to get :
D = C +/- 20mV
(b)
If the value D is more than the value C plus or minus 20 mV, adjust the gearbox again and move the gearbox plate (11) counterclockwise to get :
D = C +/- 20mV
(21)
On panel 402VU, put the A/SKID & N/W STRG switch in OFF position.
(22)
Remove the SENSOR-VOLTAGE TEST (F26792000) or SENSOR - VOLTAGE TEST (2).
(23)
Connect the electrical connector (3) to the RVDT 3GC (1).

E. Set the NWS Zero Position for the sensor 4GC NOTE : It is necessary to adjust the gear box/sensor 4GC at the same
____
value as the gear box/sensor 3GC to prevent:
-differences between the command and monitoring acquisition thresholds,
-unwanted fault messages.
(1)
On panel 402VU, make sure that the A/SKID & N/W STRG switch in OFF position.
(2)
Remove the RVDT 4GC (1) (Ref. TASK 32-51-19-000-001).
(3)
Install the ASSEMBLY TOOL (M46196) on the gearbox, put the stud (15) of the rigging tool M46196-2 (14) in the drive slot (13) of the gearbox plate (11).
(4)
Hold the rigging tool M46196-2 (14) in position and loosen the screws (12).
(5)
Lightly move the gearbox plate (11) with the rigging tool M46196-2 (14):.
-clockwise if the value C is positive
-counterclochwise if the value C is negative
(6)
TORQUE the screws (12) to between 0.1 and 0.15 m.daN (8.84 and 13.27 lbf.in).
NOTE : Make sure that the gearbox plate (11) does not move when you

Record the voltage (U1)(in AC voltage).
(c)
On the SENSOR-VOLTAGE TEST (F26792000) or SENSOR - VOLTAGE TEST
(2) set the selector switch to U2.
(d)
Record the voltage (U2)(in AC voltage).
(e)
Calculate the algebraic value E:
(U1 - U2) = E
(11) Stage 10:
Check that the algebraic value E:
