(b) TORQUE the coupling as follows:
1 TORQUE the coupling to between 70 and 80 lbf.in (0.79 and 0.90
_
m.daN).
2 Lightly hit the coupling perimeter in different places with a
_
fiber hammer.
3 TORQUE the coupling again to the specified value.
_
4 Lightly hit the coupling perimeter again.

(c) Connect the electrical connectors:
CAUTION : MAKE SURE THAT THE CONNECTORS ARE CORRECTLY LOCKED.
_______ IF THE CONNECTORS HAVE A LOCK DISPLAY WINDOW MAKE SURE THAT YOU CAN SEE THE ORANGE OR RED COLOR IN THE WINDOW. THIS SHOWS THAT THE CONNECTORS ARE CORRECTLY LOCKED.
1 Connect the electrical connectors 401VCA, 402VCA, 403VCA,
_ 404VCA, 405VCA, 406VCA, 407VCA, 408VCA, 409VCA, 447VCA and 448VCA to the pylon junction box. Tighten the connectors fingertight plus one-eighth turn with soft nose pliers. (Ref. Fig. 404A/TASK 71-00-00-991-913-A)
2 Connect the thrust reverser harness connector 4101KSA, 4101KSB
_ and 4102KSA to the thrust reverser hydraulic control unit. Tighten the connectors fingertight plus one-eighth turn with soft nose pliers. (Ref. Fig. 404A/TASK 71-00-00-991-913-A)
3 Put the harness for connector 4101KSB in the clip on the
_
Hydraulic Control Unit (HCU).
4 Connect the generator harness connector 400VCA to the forward
_ pylon junction box. (Ref. Fig. 404A/TASK 71-00-00-991-913-A)
a Do not clean the contacts with abrasive material.
_
b Do a pin retention check of the sockets (Ref. ESPM 20-48-
_ 23). Use a dynamometer, the CANNON value is 1.2 daN (2.7 lbf) minimum and the FRAMATONE (former SOURIAU) value is
2.8 daN (6.3 lbf) minimum, in accordance with pin/socket type used.
c Tighten the connector by hand until the orange (or red)
_ color is visible in the lock display (window).
5 Connect the electrical connectors 450VCA, 452VCA, 454VCA, and
_ 457VCA to the aft pylon junction box Tighten the connectors fingertight plus one-eighth turn with soft nose pliers. (Ref. Fig. 403/TASK 71-00-00-991-912)
6 Install the two clamps which attach the core harness to the
_
pylon.

C. Close access
(1) Check the High Pressure bleed and Pressure Regulating Valves configuration.
NOTE : Make sure that HP bleed and pressure regulating valves are not
____ mechanically locked and can operate freely.
(2) Make sure that the work area is clean and clear of tool(s) and other items.
(3) Remove the adhesive tape from the fan duct panels.
(4) Install the access panels :
FOR 1000EM1
473AL, 473AR
FOR 1000EM2
483AL, 483AR

(5) Install the fuel overboard drain tube at the rear of the drain mast. (Ref. Fig. 407/TASK 71-00-00-991-929)
(a) Remove the protective covers fromn the tubes.
(b) Connect the drain tube (150) the CFMI tube. Do not torque the coupling nut at this time.
(c) Connect the drain tube (150) to the bracket on the transfer gearbox with the clamp (165), the bolt (155), and the nut (160).
(d) Attach the drain tube (150) to the bracket at the bottom of the transfer gearbox with the bolt (170), the spacer (180) and the nut (185).

(e) Make sure that the drain tube (150) is aligned correctly on the engine.
(f) TORQUE the nuts (160) and (185) to between 20 and 25 lbf.in (0.22 and 0.28 m.daN).
(g) Torque the drain tube. CAUTION : USE 2 WRENCHES TO REMOVE OR INSTALL THE TUBE COUPLING
_______ NUTS. ONE WRENCH TO HOLD THE UNION AND ONE TO LOOSEN OR TIGHTEN THE COUPLING NUT. THIS WILL PREVENT DAMAGE TO THE HARDWARE.
