Remove the backshell
SUBTASK 71-51-41-350-052 Disassemble the Backshell Assembly from the Electrical Connector
Refer to Figure.
Use the Contact extraction/insertion tool, remove the contact from the hole in the electrical connector.
Remove the damaged contact
Cut the cable adjacent to the damaged contact.
Cut off the damaged contact
SUBTASK 71-51-41-350-053 Remove the Contact from the Electrical Connector
Refer to Figure.
Carefully pull the cable from the harness loom to get the same length of termination (as before the cut back of the cable).
Make sufficient cable length for the termination
SUBTASK 71-51-41-350-054 Prepare the Cable Termination
Use the Thermo stripper and remove 3 in. (76.2 mm) of the conductor insulation from the cable end.
