1–11. DEUTSCH DT SERIES CONNECTORS (12-WAY NAVISTAR VIW)
A. Connector/Terminal Repair
B. Terminal Removal (refer to Figure E–12, Views A and B)
1. Use a small-bladed screwdriver with an added notch (as shown in View B) to remove the locking
wedge that holds the terminals in place.
2. Use a small screwdriver to remove the 12-way seal plug from the rear of the connector plug or
receptacle and slide the seal up the wires out of the way, temporarily.
3. Use a small screwdriver to release the locking lever for the individual terminals that need attention.
Pull the wire and terminal out the rear of the connector.
4. If replacing the terminal, cut the wire through the middle of the terminal crimp to minimize wire
loss.
C. Terminal Crimping (refer to Figure E–11, View C)
1. Strip approximately 6–8 mm (0.236–0.315 inch) of insulation from the wire.
2. Set the crimping tool wire size to number 18. To set the wire size, remove the retainer pin. Lift and
rotate the indicator until 18 is aligned with the SEL NO. arrow. Reinstall the retainer pin.
3. Insert the contact end of the terminal down into crimping tool J 34182. Adjust the crimping tool
depth by loosening the locking ring until the depth adjusting screw is free and turning the adjusting
screw until the wire end of the terminal is just above flush with the top of the crimping hole. The
crimp jaws will now contact the middle of the terminal barrel. Tighten the lock ring to retain the
adjustment.
