1. INTRODUCTION
This instruction sheet covers operation and
maintenance of Terminating Head 58443–1 for use in
Electric Power Unit 931800–1, Pistol Grip Pneumatic
Handle Assembly 58075–1, or the Bench–Mount
Power Assembly 58338–1. Read these instructions
thoroughly before using the head.
For head installation and removal procedures, refer
to:
S 408–6789 (Pistol Grip Pneumatic Handle
Assembly 58075–1)
S 408–9393 (Bench–Mount Power Assembly
58338–1)
S 409–5746 (Electric Power Unit 931800–1)
Dimensions in this instruction sheet are in metric
units [with U.S. customary units in brackets].
Figures are for reference only and are not drawn
to scale.
Feed–ThroughHead 58443–1was designedfor
prototype cable assemblies, repair of cable
assemblies, and as an engineering tool. This
head was not designed for production type
environments.
Reasons for reissue of this instruction sheet are
provided in Section 8, REVISION SUMMARY.
2. DESCRIPTION
Feed–Through Head 58443–1 is used to terminate
18 to 26 AWG wires in MTA–156 Receptacles 640599
(with polarizing tabs) and 640604 (without polarizing
tabs). Refer to Catalog 82056 for connector informa-
tion. Slotted contacts for insulation displacement
termination are located .156–in. centerlines. Housings
are color–coded to correspond with specific wire
sizes.
The head, which is inserted into an electric power as-
sembly or bench–mount power assembly, serves as a
guide and support for the connector during termina-
tion. Features of the head (shown in Figure 1) and
functions are as follows:
Wire inserter —forces wire into the two slotted beams
of the contact. Note that it provides support for the
contact beams when applying insertion force on the
wire.
Adjuster (insertion rod) —is a piston for the wire
inserter and regulates wire inserter travel.
Feed slide —automatically positions the connector
after each termination.
Locating pawl —aligns the connector for insertion, and
retains it during termination. The locating pawl is
sometimes referred to as the “anti–backup pawl.”

3. SETUP ADJUSTMENTS AND TEST
The adjuster (insertion rod) of the wire inserter is pre-
set for 18–26 AWG wire. If the wire is being inserted
too deeply or not deeply enough inside the contact, it
may be necessary to adjust the air pressure or the
depth of the wire inserter.
3.1. For Electric Power Unit 931800–1
1. Determine the wire size, and select the
appropriate color–coded connector.
2. Using a small knife, cut off the wire retainers
(strain relief). This will provide a clear view for
inspecting the connector for a properly terminated
wire in the contact. See Figure 2.
3. Place connector in tool and make a test
termination using procedure described in Section
4, TERMINATING PROCEDURE, Steps 1 through
6. If the connector cannot be inserted into the
head, or if the connector is too loose in the head,
loosen the two screws on the insert housing (see
Figure 1) and adjust the insert housing until the
connector fits properly in the head.
4. Push the connector out of the right side of the
head.
5. Inspect termination in accordance with Section
5, INSPECTION, Steps 1 through 6.
If the wire is inserted too deeply, refer to the proce-
dure in Paragraph 3.3, Wire Insertion Depth
Adjustment.
3.2. Pistol Grip Pneumatic Handle Assembly 58075–1
and Bench–Mount Power Assembly 58338–1
1. Perform the procedure outlined in Paragraph
3.1, For Pistol Grip Manual Handle Assembly,
Steps 1 through 4.
2. Inspect termination to ensure that conductor is
terminated past the lead–in transition and is
positioned about halfway into the contact slot. See
Figure 2.
3. Inspect termination to ensure that insulation is
2.29 to 2.74 [.090 to .108] beyond the front contact
beam.
4. If, upon inspection, it is determined that the wire
is not inserted deeply enough, increase the air
pressure by 69 kPa [10 psi], and repeat the
termination and inspection procedure. Continue in
this manner until either the proper insertion depth
is obtained or the air pressure is set to 483 kPa
[70 psi]. If the proper insertion depth is not reached
at 483 kPa [70 psi], return the air pressure to
276 kPa [40 psi] and follow the procedure in
Paragraph 3.3, Wire Insertion Depth Adjustment.
If the wire is inserted too deeply, refer to the proce-
dure in Paragraph 3.3, Wire Insertion Depth
Adjustment.
3.3. Wire Insertion Depth Adjustment(Figure 3)
A. Wire Too Deep
If the wire is inserted too deep in the wire contact slot,
remove the head from the tool, and turn the adjuster
clockwise one–sixth of a revolution. The wire insertion
depth will be reduced by approximately 0.20 [.008].
Repeat the test procedure as described in Paragraph
3.1.

B. Wire Not Deep Enough
If the wire is not inserted deeply enough in contact
slot, remove the head from the tool and turn the
adjuster counterclockwise one–sixth of a revolution.
The wire insertion depth will be increased by
approximately 0.203 [.008]. Repeat the test procedure
as described in Paragraph 3.1.

4. TERMINATING PROCEDURE (Figure 4)
Determine the wire size and select the appropriate
connector. Connectors are color–coded according to
the wire sizes they will accommodate.
1. Insert connector into left side of head as shown
in Figure 4.
2. Align the contact to be terminated with the wire
inserter.
3. Be sure the locating pawl rests between the
connector index ribs.
4. Insert an unstripped wire into the funnel area
between the contact and the wire inserter until it
bottoms on the tool base.
5. Depress trigger (or squeeze cam handle) of
pistol grip handle assembly and hold it until the
inserter bottoms or the ratchet releases.
6. Release trigger (or cam handle). The inserter
will retract and the feed slide will automatically
advance connector to next contact position.
The locating pawl will move up and down as the
connectoris automaticallyadvanced throughthe
head. However, if movement is obstructed, or if
desirable, the locating pawl can be depressed
and the connector moved manually out the
RIGHT side of the head.
7. Repeat Steps 2 through 6 until all contacts have
been terminated.
8. Inspect each termination according to the
procedure in Section 5, INSPECTION, and
according to Application Specification 114–1032.

5. TERMINATION INSPECTION (Figure 2)
Inspect each termination to ensure the following:
1. Conductor is terminated past the lead–in
transition and is about halfway in the contact slot.
2. Insulation is 2.29 to 2.74 [.090 to .108] beyond
the front contact beam.
3. Wire is NOT bottomed in contact slot.
4. Contact beams are NOT deformed. If damage is
apparent, replace contacts in accordance with the
instructions packaged with the connector.
5. Insulation of wire is NOT nicked or cut in any
area other than the two wire slots.
6. Wire extends below the strain–relief features of
the connector.
Refer to Application Specification 114–1032 for more
inspection information.
6. TOOLING INSPECTION/MAINTENANCE
The following procedures have been established to
ensure the quality and reliability of your tooling. The
tooling should be checked daily, and a more detailed
inspection should be performed by your quality control
group on a regular basis.
6.1. Daily Maintenance
Each operator should be aware of, and responsible
for, the following steps of maintenance:
1. Remove dust, moisture, and other contaminants
with a clean brush, or soft, lint–free cloth. Do NOT
use objects that could damage the tool.
2. Make sure all components are in place and
properly secured.
3. Actuate the handle assembly to ensure
mechanisms inside the head move smoothly.
6.2. Quality Control Maintenance
Regular inspections should be performed by your
quality control personnel. A record of quality control
inspections should remain with the personnel respon-
sible for the tool. We recommend one inspection a
month; however, operator skill, amount of use, ambi-
ent working conditions, and your company’s
established standards are all factors in establishing
frequency of inspections.
1. Remove any accumulated film with a suitable
cleaning agent that will NOT affect plastic material.
2. Make sure all components are in place and are
properly secured.
3. Make a few test terminations and inspect the
termination in accordance with Section 5,
INSPECTION.
4. Check for chipped, cracked, worn, or broken
areas. If damage is evident, repair is necessary.
See Section 7, REPAIR.
7. REPAIR AND REPLACEMENT
Customer–replaceable parts are listed on customer
drawing 58443. A complete inventory should be
stocked and controlled to prevent lost time when
replacement of parts is necessary. Parts other than
those listed should be replaced by Tyco Electronics to
ensure quality and reliability. Order replacement parts
through your Tyco Electronics Representative, or call
1–800–526–5142, or send a facsimile of your
purchase order to 717–986–7605, or write to:
