Using Terminal Removal Tools
Using terminal removal tools
Choosing the correct tool
General
It is important to use the correct terminal removal tool when removing cable terminals. The tools are included in the repair kit or supplementary kits supplied in the future.
This section describes how to choose the correct tool by inspecting the cavity opening and the shape of the cable terminal.
If the type of cable terminal is already known, the table for cable terminals and tools in the "Special tools" section can be used.
Cavity opening and cable terminal profiles
The cavity opening in the housing has an easily identifiable profile on the connector side.
Turn the housing so that the connector side is visible.
How does the cavity profile look?
The cavity opening may be as follows:
- With one extraction groove
- With two extraction grooves
- A square profile
- A round profile
- Or housings with half-open connector sides (the cable terminal is partly exposed with a visible locking tab in the cavities).
Using terminal removal tools
Note! If the receptacle housing has a secondary locking, this must be in the open position. Always push the cable terminal forward in the cavity first. Push it towards the connector side of the receptacle housing before inserting the terminal removal tool.
The terminal removal tool shown in the following section has been inserted in the cavity from the connector side of the housing.
The cable terminal is extracted by pulling on the cable from the cable side of the housing.
The housing cavities are numbered on the inside and outside with the terminal numbers. Always check that the correct cable terminal has been removed.
If a wiring diagram is used for fault-tracing / repairs, check it against both the terminal numbers on the housing and the cable color code.
Removing cable terminals with locking tabs
Note! If the receptacle housing has a secondary locking, this must be in the open position. Always push the cable terminal forward in the cavity first. Push it towards the connector side of the receptacle housing before inserting the terminal removal tool.
The locking tab secures the cable terminal
The illustration shows the location of the cable terminal in the housing with the locking tab (the primary locking) held by a catch in the cavity.
Note! The text describes, and the illustration shows, cable terminals with a locking tab. The same principle also applies to cable terminals with two locking tabs.
Release the locking tab for the cable terminal as follows
To extract the cable terminal, the locking tab must be released (held down) with a terminal removal tool.
1. Press the cable terminal in the cavity forwards as far as it will go. This will free the locking tab from the cavity catch.
2. Insert the terminal removal tool in the cavity from the connector side of the housing. The tool presses down the locking tab. This allows the cable terminal to pass the catch in the cavity.
Hold the terminal removal tool in place.
3. Extract the cable terminal from the cable side of the housing: Pull the cable.
If the cable terminal is stuck, first remove the terminal removal tool.
What NOT to do
An example of an incorrect working method
The locking tab may be damaged if the terminal removal tool is inserted in the cavity before the cable has been pushed forwards. The cable terminal could then be difficult to extract.
In the illustration beside, there is not room for the locking tab to be pressed down by the terminal removal tool. The locking tab is pressed down by the tools towards the stop lug. It bends into a shape that will lock it in position.
