• Lead Free Status / RoHS Status: RoHS Not Applicable

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.
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 have a tapered tip to
facilitate removal of the contact (see Figure 3,
View B).
3. EXTRACTION PROCEDURE
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.

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.
These steps are recommended:
3.2. Extraction Tools 843477-5 and 843996-5
Tools 843477–5 and 843996–5 release the locking
lance from the side of the housing cavity.
Proceed as follows:
NOTE
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.
5. Repeat Steps 1 through 4 for AMPMODU MTE
housings when contact reaches preload window
(see Figure 2).
NOTE
1. Align tool so that wide part of tip is oriented with
long part of lance cavity, and tip taper is opposite
locking lance.
2. Insert tool tip between locking lance and
housing until the tool stop bottoms.
