J-38125 Terminal Repair
Kit
Removal Procedure
Follow the steps below in order to remove terminals from Micro 64 connectors.
- Locate
the lever lock on the wire dress cover. While depressing the lock, pull the lever
over and past the lock.
- Disconnect the connector from the component.
- Locate
the dress cover locking tabs at the front of the connector. Using a small flat-blade
tool push down on one of the locking tabs and pull the cover up until the dress cover
releases. Repeat this procedure for the other locking tab.
- Once the front 2 locks are unlocked, lift the front of the dress
cover and pull it forward.
- If
the connector has a nose piece, use a small flat-blade tool to remove the nose piece
by inserting the blade into the slot on the front of the connector and prying up on
the nose piece.
Important: Always use care when removing a terminal
position assurance (TPA) in order to avoid damaging it.
- Remove the TPA by inserting a small flat-blade tool into the small slot on the
TPA and pushing down until the TPA releases. Gently pry the TPA out of the connector.
Important: Be careful not to angle or rock the J 38125-13A
tool when inserting it into the connector or the tool may break.
- Insert the J 38125-13A (GM P/N 12031876-1)
tool into the round canal between the terminals cavities at the front of the connector.
See the release tool cross reference in the Reference Guide of the Terminal Repair
Kit to ensure that the correct release tool is used.
- While
holding the removal tool in place, gently pull the wire out of the back of the connector.
Always remember never use force when pulling a terminal out of a connector.
Repair Procedure
Follow the steps below in order to repair Micro 64 connector terminals.
The Micro 64 connectors have small terminals that are difficult to handle
and hold when crimping. In order to aid the technician when crimping these terminals,
a new crimping tool was developed. The J 38125-64 (M jaw) was developed to
crimp Micro 64 terminals. The J 38125-64 crimping tool has a terminal
holding block that will hold the terminal in place while the terminal is being crimped.
The J 38125-64 crimping tool is also designed to crimp both the wire and the
insulation at the same time.
After the terminal is removed from the connector perform the following procedure
in order to repair Micro 64 terminals.
Important: After cutting the damaged terminal from the
wire, determine if the remaining wire is long enough to reach the connector without
putting a strain on the wire. If the wire is not long enough, splice a small length
of the same gage wire to the existing wire, then crimp the new terminal on the added
wire.
- Cut the wire as close to the damaged terminal as possible.
- Strip 5 mm (3/16 in) of insulation from the wire.
- Depress the spring loaded locator of the crimping tool until the terminal holder
is completely visible.
- Insert terminal into the appropriate terminal holder until it hits bottom and
stops. The correct terminal holder is determined by the wire size. Also ensure that
the terminals wings are pointing towards the former on the tool and the release locator.
- Insert the stripped cable into the terminal. Insulation should be visible
on both sides of the terminal insulation wings.
- Compress the handles until the ratchet automatically releases.
- Place the terminal into the appropriate cavity and assemble the connector.
