(9) If the voltage U is not equal to 0 +/- 20mV, adjust the gear box:
(a)
Remove the RVDT 3GC (1) (Ref. TASK 32-51-19-000-001).
(b)
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).
(c)
Hold the rigging tool M46196-2 (14) in position and loosen the screws (12).
(d)
Lightly move the gearbox plate (11) with the rigging tool M46196-2 (14):.
-clockwise if the value U is less than minus 20mV
-counterclochwise if the value U is more than plus 20mV
(e)
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.
(f)
Remove the rigging tool M46196-2 (14).
(g)
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).
(h)
On panel 402VU, put the A/SKID & N/W STRG switch in ON position.
(10) Stage 2:
(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)
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 U*:
(U1* - U2*) = U*

(f)
Check that the algebraic value U*:
U* = 0 +/- 20 mV
(g)
If U* is not in the tolerance do the procedure from step (2) again.
(11)
On the panel 402VU, put the A/SKID & N/W STRG switch in OFF position.
(12)
Remove the SENSOR-VOLTAGE TEST (F26792000) or SENSOR - VOLTAGE TEST (2).
(13)
Connect the electrical connector (3) to the RVDT 3GC (1).
(14)
Do the procedure again for the RVDT 4GC (monitor channel).
(15) On the panel 402VU, put the A/SKID & N/W STRG switch in ON position. Subtask 32-51-00-865-110
