      2. Cut and remove the lockwire from the screws, the coupling nut, the shell and the connector.

      1. Be careful not to cause damage to the lockwire holes.

      3. If the backshell is not a straight type, make a mark on the shell which aligns with the master keyway.

    4. Remove the screws and the strain-relief clamp from the coupling nut.

      5. Remove the coupling nut from the shell.

      1. Use the applicable Strap Wrench - (BT-BS-611 or TG-70).

      2. Move the coupling nut and the grounding ferrule away from the shell.

      3. Be careful not to cause damage to the ground-shields of the cables.

      6. Remove the shell from the connector.

      1. Use the applicable Strap Wrench - (BT-BS-611 or TG-70).

      2. Move the shell away from the connector.

      3. Be careful not to cause damage to the ground-shields of the cables.

    2. SUBTASK 23-44-41-350-054 Remove the Contacts from the Connector

    1. Refer to Figure.

      2. Attach a temporary identification tag to each of the cables in the connector.

      1. Write on the tag the number of the connector hole from which the cable came.

      3. Remove a contact from the connector.

      1. Use the applicable Extractor/inserter tool - (16g or 20g).

      2. Put the cable in the groove of the tool.

      3. Push the tool along the cable and into the rear of the connector, until it touches the contact (the tool will open the collet).

      4. Hold the cable and the tool together and remove the contact from the rear of the connector.

      4. Remove the remaining contacts from the connector.

      1. Do Step again, for the remaining contacts.

    3. SUBTASK 23-44-41-350-055 Remove the Components of the Connector Assembly

      1. Remove the shell, the grounding ferrule and the coupling nut, from the harness.

      1. Be careful not to cause damage to the contacts of the ground-shields.

    4. SUBTASK 23-44-41-220-054 Examine the Components

      1. Examine the connector, the contacts, the coupling nut, the grounding ferrule, the screws and the shell.

      1. Refer to INSPECTION-001 TASK 23-44-41-200-301.

      2. Reject the parts which are unserviceable.

    5. SUBTASK 23-44-41-350-056 Install the Replacement Components of the Connector Assembly

      CAUTION

      THE REPLACEMENT COMPONENTS MUST HAVE THE SAME PART NUMBERS AS THE COMPONENTS WHICH WERE REMOVED. INCORRECT COMPONENTS CAN CAUSE DAMAGE TO THE SYSTEM.

    1. Refer to Figure.

      2. Install the new, or serviceable, components to the harness.

      1. Install the components in the sequence that follows: the coupling nut, the grounding ferrule and the shell.

      2. Be careful not to cause damage to the contacts or the ground-shields.

    6. SUBTASK 23-44-41-350-057 Install the Contacts to the Connector

      CAUTION

      THE CONTACTS MUST BE INSTALLED IN THEIR CORRECT POSITIONS IN THE CONNECTOR. IF THEY ARE INSTALLED IN THE INCORRECT POSITIONS, THE SYSTEM CAN BE DAMAGED.

    1. Refer to Figure.

      2. Find the contact which must be installed in the center hole of the connector.

      1. You must install the contacts at the center of the connector first and work out.

      3. Install the center contact to the connector.

      1. Use the applicable Extractor/inserter tool - (16g or 20g).

      2. Put the cable in the groove of the tool.

      3. Push the tool along the cable until it touches the flange of the contact.

      4. Hold the cable and the tool together and use the tool to push the contact into the connector hole.

      5. When the contact is in the correct position, in the connector hole, release the cable and remove the tool.

      6. Lightly pull the cable to make sure that the contact is engaged correctly in the connector.

      4. Install the remaining contacts to the connector.

      1. Do Step again, for the remaining contacts.

      2. Make sure the contacts are installed in the positions noted, during their removal.

      3. Install the contacts nearest to the center first.

      5. Remove the identification tags from the cables.

      1. Remove the temporary tags, which were installed in Step.

    7. SUBTASK 23-44-41-350-058 Assemble the Connector Assembly

    1. Refer to Figure.

      2. Install the shell to the connector.

      1. Use the applicable Strap Wrench - (BT-BS-611 or TG-70), to tighten the shell.

      2. If the backshell is not a straight type, align the mark (made in Step ) with the master keyway.

      3. Install the coupling nut to the shell.

      1. Put the ground-shields and equal distance apart around the shell.

      2. Push the ground ferrule along the harness, until it touches the ground-shields.

      3. Put the ground-shields through the coupling nut.

      4. Install the coupling nut to the shell.

      5. Use the Torque Wrench - 0 to 1000 lbf.in range and the applicable Strap Wrench (BT-BS-611 or TG-70), to torque the coupling nut to 10 lbf in. (1.13 Nm).

      4. Install the strain-relief clamp to the coupling nut.

      1. Make sure that all of the twists and bends are out of the cables.

      2. Attach the clamp to the coupling nut with the two screws.

      3. Use the Torque Wrench - 0 to 1000 lbf.in range to torque the screws to between 10 and 20 lbf in. (1.13 and 2.26 Nm).

    8. SUBTASK 23-44-41-750-052 Do a Continuity and Insulation Test on the Connector Assembly
