      2. Remove the backshell nut.

      1. Install the electrical connector assembly to the IAE 3J12704 Wrench and holder or equivalent, 1off. Disconnect the backshell nut and move it along the cables.

    3. SUBTASK 71-52-43-360-015 Applying the Tape

      NOTE

      The wires must be dry before starting the task. If the wires are damp, use the cloth to wipe it. If any reparable damage found on harness – it has to be repair first.

    1. Wrap the tape around wires in place of backshell welded point. The minimum number of wrapped layers should be five. More layers are desirable. Note to allow sufficient gap between harness outer diameter and backshell inner diameter for backshell reassembling without damaging or moving the tape.

    4. SUBTASK 71-52-43-360-016 Install the Backshell to the Electrical Connector or Receptacle

      NOTE

      Make sure the key-way of the connector or receptacle aligns with the marks you made on the backshell.

      2. Install the backshell.

      1. Install the electrical connector or receptacle assembly to the IAE 3J12704 Wrench and holder or equivalent, 1 off. Attach the backshell to the electrical connector or receptacle and tighten the nut by hand. Tighten the backshell nut through 90 degrees with the IAE 3J12704 Wrench and holder.

      3. Install the other backshell parts.

      1. Put the screen tails equally around the split ring cone surface and through the ID of the upper ring and washer. Attach and tighten the backshell nut so the different parts hold the screen braid tails. Trim the tails and shrink the sleeve over them.

    5. SUBTASK 71-52-43-360-017 Finish the Harness Adjacent to the Electrical Connector or Receptacle

      1. Install the cable ties, bush, and clamp bar adjacent to the electrical connector or receptacle.
