4 Attach the clamp (10) and the clamp (25) to the bracket on the
_ HCU with the screw (15) and nut (20).
5 TORQUE the nut (20) to between 20 and 25 lbf.in (0.22 and 0.28
_
m.daN).
6 Connect the generator harness connector 400VCA to the forward
_ pylon junction box. (Ref. Fig. 404/TASK 71-00-00-991-913)
a Do not clean the contacts with abrasive material.
_ R b_ Do a pin retention check of the sockets (Ref. ESPM 20-48-R 23). c Tighten the connector by hand until the orange (or red)
_ color is visible in the lock display (window).
7 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)
8 Install the two clamps which attach the core harness to the
_
pylon.
NOTE : Make sure that you install the correct clamps on the
____ core harness. Two clamp sizes (diameter) can be found depending on the core harness diameter.

Subtask 71-00-00-410-094-A
B. Install these components: 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.
(1) Install these components on the left side of the engine :
(a) Connect the fan lower zone extinguishing line forward of the hydraulic junction box. TORQUE union to between 800 and 900 lbf.in (9.04 and 10.17 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.
_
5 TORQUE the coupling again to the specified value.
_
