Figure 1

PRO–CRIMPER III Hand Crimping Tool Assembly

91381–1 consists of Die Assembly 91381–2 and

PRO–CRIMPER III Hand Tool Frame 354940–1. See

Figure 1. The die assembly consists of crimping dies

and a locator assembly.

Read these instructions thoroughly before crimping

any contacts.

Reasons for reissue are provided in Section 11,

REVISION SUMMARY.

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.

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.

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.

3. Place a contact with wire into the proper nest

and close the tool handles until the ratchet reaches

the sixth click, or until the contact support touches

the contact.

4. Slightly loosen the nut that 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.

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.
