NUMBERS, TOOL PART NUMBERS, AND REPAIR INSTRUCTIONS
1–3. PACKARD METRI-PACK 150 SERIES CONNECTORS — PUSH-TO-SEAT
(OIL LEVEL SENSOR)
A. Connector/Terminal Repairs
NOTE: Do not solder crimps.
B. Terminal Removal
1. Remove the secondary lock.
2. Insert needle end of terminal remover J 35689-A into the small notch between the connector and
the terminal to be removed (Figure E–3, View A). Push the lock tang toward the terminal.
3. Pull the wire and terminal out the rear of the connector (this is a “push-to-seat” terminal).
4. Pull terminal as far as necessary from the connector. This will be limited by the number of other
wires inserted into the connector and by the distance between the back side of the connector and
the beginning of the harness covering.
5. If terminal is to be replaced, cut the terminal between the core and insulation crimp to minimize
wire loss.
C. Terminal Crimping
1. Carefully strip insulation 4.5 mm ± 0.5 mm (0.18 ± 0.02 inch). Unless insulation crimp is
overtight, Automatic Wire Stripper J 35615 will remove insulation and crimp from old terminal
without damaging wire.
2. Place core crimp portion of terminal on bed of anvil “E” and squeeze crimper enough to keep
terminal from dropping (Figure E–3, View B).
3. Position wire core in terminal and squeeze crimper tool to complete the core crimp.
Be sure to
orient the terminal so that it is properly aligned with the terminal cavity in the connector.
The terminal should be positioned so that the lock tang is on the side of the cavity which has the
notch in the middle (for the remover tool).
4. Position insulation crimp of terminal on anvil “C” so that the entire insulation crimp area and a
portion of the terminal between the core and insulation crimp areas are supported by the anvil.
Complete the insulation crimp.
