1. INTRODUCTION

This instruction sheet covers hand crimping tools 576778, 576779, 576780, 576781, 576782, 576783, and

576784, which are used to crimp PIDG PEEK STRATO-THERM Terminals to the wire sizes listed in Table 1.

Table 1: Crimping specifications

NOTE

Dimensions in this instruction sheet are in millimeters with [inches in brackets]. Figures are for reference only and are not

drawn to scale.

Read these instructions thoroughly before crimping connectors.

2. DESCRIPTION

Each tool features a head containing two stationary crimping dies (anvils) and two movable crimping dies

(indenters), a locator, an insulation crimping adjustment pin, and a CERTI-CRIMP hand crimping tool ratchet

control (see Figure 1).

When the handles are closed, the crimping dies form one crimping chamber with two sections: an insulation

barrel section and a wire barrel section. The insulation barrel section crimps the terminal onto the wire

insulation. Simultaneously, the wire barrel section crimps the terminal wire barrel onto the stripped wire. The

locator positions the terminal in the crimping chamber. The insulation crimping adjustment pin is used to

regulate the height of the insulation crimp.

The CERTI-CRIMP hand crimping tool ratchet control ensures full crimping of the terminal. After it is engaged,

the ratchet does not release until the tool handles are fully closed.

CAUTION

The dies bottom before the ratchet releases. This feature ensures maximum tensile performance of the crimp. This design

feature ensures maximum electrical and tensile performance of the crimp Do not re-adjust the ratchet.

3. CRIMPING

NOTE

Refer to section 5 for information on insulation crimp adjustment.

1. Verify that the terminal insulation color code matches the tool handle color.

2. Select a wire of the correct size and insulation diameter for the terminal (see Table 1). Do not use wire

with nicked or missing conductors.

3. Strip the wire to the length listed in Table 1. Do not nick or cut wire strands.

4. Select an applicable contact and identify the appropriate crimp section according to the wire size

markings on the tool.

5. Squeeze the tool handles together until the ratchet releases and allow them to open fully.

6. Place the terminal in the dies so the wire barrel butts against the locator (Figure 2).

7. Close the handles of the tool until the contact is lightly held by the die set, but is not deformed to the

point where the wire cannot enter freely.

8. Insert the wire into the crimp barrel of the contact until it butts against the locator.

CAUTION

Do not allow wire insulation to enter the terminal wire barrel.

9. While holding the wire in place, fully cycle the tool until the ratchet releases and allows the handle to

open.

10. Remove the crimped terminal.

11. Examine the dot code on the finished crimp to ensure that the correct terminal and tool combination

was used (Table 1).

12. Inspect the crimp as described in section 4.

4. INSPECTING THE CRIMP

Inspect crimped terminals by checking the features shown in Figure 3. Poor crimps (Figure 4) can be avoided

by carefully following the procedures provided in section 3, and by following the tool maintenance procedures

provided in section 6.

Figure 3: Features of a good crimp

Insulation barrel is in firm contact with wire insulation.

Correct color code, dot code, and tool combination.

Wire size matches wire range or size stamped under tongue.

Crimp is centered on wire barrel.

Bare wire ends are flush with (or extend slightly beyond) end of wire barrel.

Wire insulation does not enter wire barrel.

No nicked or missing wire strands.

Figure 4: Features of a poor crimp

Wire insulation is extruded.

Incorrect color code, dot code, and tool combination.

Wire size does not match wire range or size stamped under tongue.

Crimp is not centered on wire barrel.

Wire not inserted far enough to reach end of wire barrel.

Wire insulation enters wire barrel. Check for incorrect strip length.

Nicked or missing wire strands.

5. ADJUSTING THE INSULATION CRIMP

The insulation crimping section of the hand tool has an adjustment pin that controls the tightness of the crimp.

This pin has three positions (Figure 5).

Figure 5: Insulation crimp adjustment pin

Tight

Medium

Loose

To adjust the crimp tightness, complete the following steps.

1. Insert the insulation crimp adjustment pin into the number 3 (loose) position.

2. Place the terminal into the crimping jaws (Figure 2).

3. Insert the unstripped wire into only the insulation barrel of the terminal (Figure 2).

4. Close the tool handles to complete the crimp.

5. Removed the crimped terminal and check the insulation crimp by bending the wire back and forth once.

The terminal should retain its grip on the wire insulation.

6. If the wire pulls out, tighten the crimping section by setting the insulation crimp adjustment pin to the

number 2 (medium) position.

7. Perform another crimp and repeat the adjustment as needed until the correct insulation grip is

achieved. Do not use a tighter setting than necessary.

6. MAINTENANCE AND INSPECTION

The hand tool is inspected before being shipped. Inspect it immediately upon arrival to ensure that it was not

damaged during shipment.

6.1. Daily maintenance

Make each operator of the power unit aware of, and responsible for, the following daily maintenance

requirements:

Remove dust, moisture, and other contaminants with a clean, soft brush or soft, lint-free cloth. Do not

use objects that could damage the dies.

Remove all lubrication and accumulated film by immersing the tool (with the handles partially closed) in

a suitable commercial degreaser.

Ensure that the retaining pins are in place and secured with retaining rings.

Protect all pins, pivot points, and bearing surfaces with a thin coat of any good SAE 20 motor oil. Do

not oil excessively.

When the tool is not in use, keep handles closed to prevent objects from becoming lodged in the

crimping jaws. Store the tool in a clean, dry area.

6.2. Lubrication

Lubricate all pins, pivot points, and bearing surfaces with SAE 20 motor oil as indicated in Table 2. Wipe

excess oil from the tool, particularly from the crimping area. Oil transferred from the crimping area onto

terminations can affect the electrical characteristics of an application.

6.3. Visual inspection

Regular inspections should be performed at least once per month by quality control personnel. A record of

scheduled inspections should remain with the dies or be supplied to personnel responsible for the dies. Base

your inspection frequency on the amount of use, ambient working conditions, operator training and skill, and

established company standards. Perform the inspection as follows:

Close the tool handles until the ratchet releases and then allow them to open freely. If they do not open

quickly and fully, the spring is defective and must be replaced. See section 7, REPLACEMENT AND

REPAIR.

Inspect head assembly for worn, cracked, or broken jaws. If damage is evident, return the tool to TE for

evaluation and repair. See section 7, REPLACEMENT AND REPAIR.

To gage die closure, complete the following steps.

1. Remove traces of oil or dirt from the crimping chamber and plug gage.

2. Close the tool handles until the wire barrel dies are bottomed. Do not apply additional pressure to the

tool handles.

3. With wire barrel dies bottomed, inspect the wire barrel crimp die closure using the proper plug gage.

Press the spring-loaded locator down and hold the gage in alignment with the die closure.

4. Align the GO element with the wire barrel section of the crimping chamber (Figure 8). Push the element

straight into the crimping chamber without using force. The GO element must pass completely through

the crimping chamber.

5. Align the NO-GO element and try to insert it straight into the same section of the crimping chamber.

The NO-GO element can start entry, but must not pass completely through the crimping chamber

(Figure 8).

1. Insert the insulation crimping adjustment pin in position 1 (Figure 9).

2. With the crimping dies bottomed, check the insulation barrel section of the crimping chamber (Figure 9)

as described in steps 4 and 5.

If the crimping chamber conforms to the gage inspection, the tool is considered dimensionally

correct. Lubricate it with a thin coat of any good SAE 20 motor oil.

If not, the tool must be returned to TE for further evaluation and repair. Refer to section 7,

REPLACEMENT AND REPAIR.

For additional information regarding the use of plug gages, refer to instruction sheet 408-7424.

6.5. Inspecting the ratchet control

The CERTI-CRIMP hand crimping tool ratchet control feature on TE hand tools must be checked to ensure that

the ratchet does not release prematurely, allowing the dies to open before they have fully bottomed.

1. Obtain a 0.025 mm [.001 in.] shim that is suitable for checking the clearance between the bottoming

surfaces of the crimping dies.

2. Select the maximum size wire for the tool and a terminal.

3. Position the terminal and wire between the crimping dies as described in section 3.

4. While holding the wire in place, squeeze the tool handles until the CERTI-CRIMP hand crimping tool

ratchet control releases. Hold the handles in this position, maintaining just enough tension to keep the

dies closed.

5. Check the clearance between the bottoming surfaces of the crimping dies with the 0.025 mm [.001 in.]

shim.

If the clearance is 0.025 mm [.001 in.] or less, the ratchet is considered satisfactory.

If the clearance exceeds 0.025 mm [.001 in.], the ratchet is out of adjustment and must be

repaired.
