1. INTRODUCTION

PRO-CRIMPER III Hand Crimping Tool Assembly

90871-1 consists of Die Assembly 90871-2 and PRO-

CRIMPER III Hand Crimping Tool Frame 354940-1.

The die assembly consists of crimping dies and a

locator assembly.

Read these instructions thoroughly before crimping

any contacts.

REVISION SUMMARY.

2. DESCRIPTION (Figure 1 and Figure 2)

The tool features a tool frame with a stationary jaw

and handle, a moving jaw, a moving handle, and an

adjustable ratchet that ensures full contact crimping.

The tool frame holds a die assembly with two crimping

sections.

The die assembly features a wire anvil, an insulation

anvil, a wire crimper, and an insulation crimper.

Attached to the outside of the frame is a locator

assembly, which contains a locator, a spring retainer,

and a contact support.

Die retaining pins and die retaining screws are used to

position and secure the dies in the tool frame. A nut is

used on the upper die retaining screw to hold the

locator assembly in place.

3. INSTALLATION AND REMOVAL OF DIE SET AND

LOCATOR ASSEMBLY (Figure 2)

1. Open the tool handles and remove the two die

retaining screws from the tool jaws.

2. Place the wire anvil and insulation anvil so that

their chamfered sides and their marked surfaces

face outward, when mounted in the moving jaw of

the tool frame.

3. Insert the two die retaining pins.

4. Insert the short die retaining screw through the

jaw and through both anvil dies, and tighten the

screw just enough to hold the dies in place. Do not

tighten the screw completely at this time.

5. Place the wire crimper and insulation crimper so

that their chamfered sides and their marked

surfaces face outward, when mounted in the

stationary jaw of the tool frame.

6. Insert the two die retaining pins.

7. Insert the long die retaining screw through the

jaw and through both crimper dies, and tighten the

screw just enough to hold the dies in place. Do not

tighten the screw completely at this time.

8. Carefully close the tool handles, making sure that

the anvils and crimpers align properly. Continue

closing the tool handles until the ratchet in the tool

frame has engaged sufficiently to hold the anvils

and crimpers in place, then tighten both die

retaining screws.

9. Place the locator assembly over the end of the

long screw, and position the locator assembly

against the side of the tool jaw.

10. Place the nut onto the end of the long screw and

tighten the nut enough to hold the locator assembly

in place, while still allowing the locator to slide up

and down.

11. To disassemble, close the tool handles until the

ratchet releases, remove the nut, the locator

assembly, the two die retaining screws, and the four

die retaining pins, and slide the anvils and crimpers

out of the tool jaws.

4. CONTACT SUPPORT ADJUSTMENT (Figure 3)

NOTE

The contact support is preset priorto shipment, but

minor adjustment may be necessary.



1. Make a sample crimp and determine if the

contact is straight, bending upward, or bending

downward.

2. If adjustment is required, loosen the screw that

holds the contact support onto the locator assembly.

NOTE

408-9966

3of 6

Rev C

The ratchet has detents that create audible clicks

as the tool handles are closed.

3. Place a contact with wire into the proper nest and

close the tool handles until the ratchet reaches the

sixt# click, or until the contact support touches the

contact.

4. Slightly loosen the nutthat holds the locator

assembly onto the tool frame.

5. Move the contact support as required to eliminate

the bending of the contact.

6. Tighten the nut and close the handles until the

ratchet releases.

7. Remove and inspect the contact.

8. Make another sample crimp. If the contact is

straight, tighten the contact support screw. If the

contact is still being bent during crimping, repeat the

adjustment procedure.

5. CRIMPING PROCEDURE

NOTE

This tool is provided with a crimp adjustment

feature. Initially, the crimp height should be verified

as specified in Figure 4. Refer to Section 6, Crimp

Height Inspection, and Section 7, RATCHET

Adjustment, to verify crimp height before using the

tool to crimp desired contacts and wire sizes.

Refer to the table in Figure 1 and select wire of the

specified size and insulation diameter. Strip the wire to

the length indicated in Figure 1, taking care not to nick

or cut wire strands. Select an applicable contact and

identify the appropriate crimp section according to the

wire size markings on the tool. Refer to Figure 3 and

proceed as follows:

1. Hold the tool so that the back (wire side) is facing

you. Squeeze tool handles together and allow them

to open fully.

2. Holding the contact by the mating end, insert the

contact - insulation barrel first - through the front of

the tool and into the appropriate crimp section.

3. Position the contact so that the mating end of the

contact is on the locator side of the tool, and so that

the open "U" of the wire and insulation barrels face

the top of the tool. Place the contact up into the nest

so that the movable locator drops into the slot in the

contact. Refer to Figure 3. Butt the front end of the

wire barrel against the movable locator.

CAUTION

Make sure that both sides of the insulation barrel

are started evenly into the crimping section. Do not

attempt to crimp an improperly positioned contact.

4. Hold the contact in position and squeeze the tool

handles together until ratchet engages sufficiently to

hold the contact in position. Do NOT deform

insulation barrel or wire barrel.

5. Insert stripped wire into contact insulation and

wire barrels until it is butted against the wire stop, as

shown in Figure 3.

6. Holding the wire in place, squeeze tool handles

together until ratchet releases. Allow tool handles to

open and remove crimped contact.

NOTE

Thecrimpedcontactmaystickinthecrimpingarea,

but the contact can be easily removed by pushing

downward on the top of the locator (see Figure 3).

7. Check the contact's crimp height as described in

Section 6, Crimp Height Inspection. If necessary,

adjust the crimp height as described in Section 7,

RATCHET ADJUSTMENT.

6. CRIMP HEIGHT INSPECTION

Crimp height inspection is performed through the use

of a micrometer with a modified anvil, commonly

referred to as a crimp-height comparator. TE does not

manufacture or market crimp-height comparators.

Detailed information on obtaining and using crimp-

height comparators can be found in instruction sheet

408-7424.

Proceed as follows:

1. Refer to Figure 4 and select a wire (maximum

size) for each crimp section listed.

2. Refer to Section 5, CRIMPING PROCEDURE,

and crimp the contact(s) accordingly.

3. Using a crimp height comparator, measure the

wire barrel crimp height as shown in Figure 4. If the

crimp height conforms to that shown in the table,

the tool is considered dimensionally correct. If not,

the tool must be adjusted. Refer to Section 7,

RATCHET (Crimp Height) ADJUSTMENT.

7. RATCHET (Crimp Height) ADJUSTMENT (Figure 5)

1. Remove the lockscrew from the ratchet

adjustment wheel.

2. With a screwdriver, adjust the ratchet wheel from

the locator side of the tool.

3. Observe the ratchet adjustment wheel. If a tighter

crimp is required, rotate the adjustment wheel

COUNTERCLOCKWISE to a higher-numbered

setting. If a looser crimp is required, rotate the

adjustment wheel CLOCKWISE to a lower-

numbered setting.

4. Replace the lockscrew.

5. Make a sample crimp and measure the crimp

height. If the dimension is acceptable, replace and

secure the lockscrew. If the dimension is

unacceptable, continue to adjust the ratchet, and

again measure a sample crimp.

8. MAINTENANCE

Ensure that the tool and dies are clean by wiping them

with a clean, soft cloth. Remove any debris with a

clean, soft brush. Do not use objects that could

damage the tool. When not in use, keep handles

closed to prevent objects from becoming lodged in the

crimping dies, and store in a clean, dry area.

9. VISUAL INSPECTION

The crimping dies should be inspected on a regular

basis to ensure that they have not become worn or

damaged. Inspect the crimp sections for flattened,

chipped, worn, or broken areas. If damage or

abnormal wear is evident, the tool must be replaced.

See Section 10, REPLACEMENT.

10. REPLACEMENT

Customer-replaceable parts are shown in Figure 1.

Available separately, PRO-CRIMPER III Hand

Crimping Tool Repair Kit 679221-1 includes a

replacement nut and a variety of pins, rings, screws,

and springs.

If the dies are damaged or worn excessively, they

must be replaced.
