4. Procedure_________
(Ref. Fig. 401/TASK 71-51-43-991-300, 402/TASK 71-51-43-991-301)
Subtask 71-51-43-420-053
A. Installation of the Generator Power Harness
NOTE : For the recommended procedure for the installation of the wire
____
harness (Ref. TASK 70-60-00-910-041)>.
(1) Remove the protective covers from the electrical connectors on the harness (5) and the pylon junction box.
(2) Make sure that the electrical connectors are clean and in the correct condition.
(3) Do not clean the contacts with abrasive material.
(4) Put the electrical harness (5) in position on the engine.
(5) Connect the electrical connector 400VC-A to the pylon junction box.
(a) Tighten the connector by hand until the colored marking is visible in the lock display (window).

(6) Put the harness (5) into the clamps (10). Make sure that the harness is correctly installed on the engine.
(7) Tighten the captive screws 1/4 turn clockwise to engage the cam nuts.
(8) Clean the mating surfaces:
WARNING : TRICHLOROETHANE IS A HAZARDOUS MATERIAL THAT CAN CAUSE
_______ INJURY OR ILLNESS IF NOT CORRECTLY USED. BEFORE YOU USE THIS PRODUCT, READ THE APPLICABLE MANUFACTURER'S "MATERIAL DATA SAFETY SHEET" AND OBEY THE SAFETY AND HEALTH PRECAUTIONS.
(a) Clean the mating surfaces of the ground cable terminals and the bracket with 1,1,1, trichloroethane (Material No. CP11-002) and a lint-free cloth.
(9) Attach the harness cables (5) tothe bracket with the bolt (30), the lockwasher (15), the washer (25), and the nut (20). Remove the tags.
(10) TORQUE the nut (20) to between 95 and 110 lbf.in (1.07 and 1.24 m.daN).
(11) Attach the harness cables (50), (55), (60) and (65) to the IDG terminals with the washers (45), the lockwashers (40) and the nuts (35).
(12) TORQUE the nuts (35) to between 144 and 168 lbf.in (1.62 and 1.89 m.daN).
(13) Install the cover (75) on the IDG terminal with the CFMI supplied screws (70).
(14) TORQUE the screws (70) to between 20 and 22 lbf.in (0.22 and 0.24 m.daN).
(15) Do an electrical bond resistance check as follows:
NOTE : The electrical bond resistance procedure that follows is
____ applicable for the electrical harness ground cables.
(16) Put one lead of the ohmmeter on the ground cable terminal near the bolt (30).
(17) Put the other lead of the ohmmeter on the top surface of the bracket.

(18) The resistance measured between the ohmmeter leads must not be more than 0.001 ohm.
(19) If the resistance is more than 0.001 ohm, remove the applicable hardware and clean the mating surfaces again. Do this procedure until the resistance is less than 0.001 ohm. 中國航空網(wǎng) www.k6050.com 航空翻譯 www.aviation.cn 本文鏈接地址：A320飛機維護手冊 AMM 動力裝置 POWER PLANT 2(18)
