have a tapered tip to facilitate removal of the contact

(see Figure 3, View B).

Since Mod IV housings will accept contacts with

both the old style and the new style locking lance,

NOTE

3. EXTRACTION PROCEDURE

the selection of the correct tool depends on which

contact is being extracted. Information about the

contacts and housings can be found in Catalog

1307819. Contacts with the old style locking lances

will gradually be phased out.

If extracting Mod IV, Mod IV.v, or Mod V contacts, first

determine whether the contact has an old style or a

new style locking lance. Then select the tool

recommended for your particular contact. Use

Figure 2 when extracting MTE, tandem spring, or mini

tandem spring contacts. When you are sure you have

the correct tool for your particular application, proceed

to Paragraph 3.1 or 3.2.

2. DESCRIPTION

Each tool features a handle marked with the specific

part number, a contact lance release tip, a locking

lance reset portion, and a tool stop. The contact lance

release tip depresses the contact locking lance to

allow extraction of the contact. The tool stop prevents

over-insertion of the tip. The lance reset portion

repositions an overly depressed locking lance to the

proper height - assuring retention of the contact in the

housing.

3.1. Extraction Tools 843477-1, -2, -3, -4 and Tools

843996-2, -3, -4 (Figure 3, View A)

Tools represented in View A of Figure 3 release the

locking lance from the top of the housing cavity as

shown.

The tip of the locking lance will be visible in

housings requiring these tools.

NOTE

Generally, all tools except tools 843477-5 and 843996-

5 can be classified as top release tools in that - during

the extraction process - they are inserted into the top

of the housing to depress the locking lance from the

top, as shown in Figure 3, View A. On the other hand,

tools 843477-5 and 843996-5 are called side release

tools. Although they are inserted from the top (see

View B, Figure 3), each side release tool is designed

for a contact which is retained in the housing with its

locking lance lodged into the side of the housing

cavity. Housings of this style are called side release

housings. Note that tools 843477-5 and 843996-5

These steps are recommended:

1. Orient the wide part of tip with the narrow part of

locking lance cavity.

2. Insert tool tip into BACK of lance cavity until tool

stop bottoms on housing.

3. Holding tool in position, grip wire and pull contact

out of housing.

4. Remove tool from housing.

(see Figure 2).

retention in the housing. Check compatibility of the

contact and tool; then proceed as follows:

1. Orient the reset tip so the taper is facing the

locking lance.

3.2. Extraction Tools 843477-5 and 843996-5

(Figure 3, View B)

2. Keep the reset tip flat against the receptacle box

and slide it toward the base of the locking lance until

it bottoms.

Tools 843477-5 and 843996-5 release the locking

lance from the side of the housing cavity.

3. Remove tool tip and contact will be ready for re-

insertion into the housing.

The edge of the locking lance will be visible in

housings requiring this tool.

NOTE

Damaged product should not be used. If a

damaged contact is evident, it should be cut from

the wire and replaced with a new one. If a damaged

housing is evident, it should be replaced.

CAUTION

Proceed as follows:

1. Align tool so that wide part of tip is oriented with

long part of lance cavity, and tip taper is opposite

locking lance.

5. TOOL INSPECTION/MAINTENANCE

Tools 843477-[ ] and 843996-[ ] should conform to the

dimensions listed in Figure 4. It is recommended that

each tool be inspected upon its arrival to be sure it has

not been damaged in transit and at regularly

2. Insert tool tip between locking lance and housing

until the tool stop bottoms.

3. Pull back lightly on the wire and, if necessary,

move tool just enough to release the lance.

scheduled intervals to be sure it remains functional.

4. Remove the contact from the housing; then

remove the tool.

6. REVISION SUMMARY

Since the previous release of this sheet, the new

company logo has been applied.
