3. INSTALLATION AND REMOVAL OF DIE 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 indenter and insulation indenter 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 indenter 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 indenters align properly. Continue
closing the tool handles until the ratchet in the tool frame has engaged sufficiently to hold the anvils
and indenters in place, then tighten both die retaining screws.
9. To remove, close the tool handles until the ratchet releases, remove the two die retaining screws and
the four die retaining pins, and slide the anvils and indenters out of the tool jaws.
4. CRIMPING PROCEDURE
NOTE
This tool is provided with a crimp adjustment feature. Initially, the crimp height should be verified as specified in Figures 5
and 6. Refer to Section 5, Inspection, and Section 6, Crimp height Adjustment, to verify crimp before using the tool to crimp
desired connectors and wire sizes.
Slide the ferrule onto the cable and strip the cable according to the dimensions provided in the instructions
packaged with the connector. Take care not to nick or cut wire strands. Proceed as follows:

4.1. Center Contact (Figure 3)
1. Slide center contact onto stripped conductor. Insert center contact assembly into the partially closed
center contact crimping chamber on the anvil die. Make sure the center contact flange is against the
edge of the die as shown in Figure 3.
2. While holding the cable in place, crimp the center contact by closing the tool handles until the ratchet
releases.
3. Allow the handles to open fully, and remove the crimped center contact from the die assembly.

4.2. Ferrule (Figure 4)
1. Flare the cable braid and insert the crimped center contact into the connector body until the cable
dielectric is against the dielectric inside the connector body. The flared braid will then fit over the
support sleeve of the connector body.
2. Slide the ferrule forward over the braid until the ferrule is against the connector body.
3. Place the ferrule in the crimping chamber on the anvil die so that the shoulder of the connector body is
against the edge of the die. Refer to Figure 4.
4. Holding the assembly in place, close the tool handles until the ratchet releases.
5. Allow the handles to open fully, and remove the crimped assembly from the die assembly.

5. INSPECTION
5.1. Visual Inspection
The crimping dies should be inspected on a regular basis to ensure that they have not become worn or
damaged. Inspect the crimping chambers for flattened, chipped, worn, or broken areas. If damage or abnormal
wear is evident, the dies must be replaced. See Section 8, DIE REPLACEMENT.
5.2. Periodic Inspection
Center Contact Crimp Height Inspection
This inspection requires the use of a micrometer with a modified anvil as shown in Figure 5.
NOTE
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 market crimp height comparators. Refer to Instruction Sheet 408-7424 for detailed information
on obtaining and using a crimp height comparator.
Proceed as follows to check the crimp height of the center contact:
1. Select the center contact for the connector.
2. Refer to Section 4, CRIMPING PROCEDURE, and crimp the center contact accordingly.
3. Using a crimp height comparator, measure the crimp height as shown in Figure 5. If the crimp height
conforms to that shown, the die assembly is considered dimensionally correct. If not, return the dies to
TE for evaluation and repair (refer to Section 8, DIE REPLACEMENT).
Figure 5
Gaging the Ferrule Crimping Chamber
This inspection requires the use of a plug gage conforming to the dimensions in Figure 6. TE does not
manufacture or market these gages. To gage the ferrule crimping chamber, proceed as follows:
1. Close the jaws until the dies have bottomed, then HOLD the frame handles in this position. Do NOT
force the dies beyond initial contact.
2. Align the GO element with the ferrule crimping chamber. Push the element straight into the crimping
chamber without using force. The GO element must pass completely through the crimping chamber.
3. Align the NO-GO element and try to insert it straight into the same crimping chamber. The NO-GO
element may start entry, but must not pass completely through.
4. Repeat Steps 2 and 3 for the insulation ferrule section of the crimping chamber.
NOTE
Insert the gage element for the insulation ferrule section into the back of the crimping chamber. The GO element for this
section will not pass completely through the crimping chamber.

If the crimping chamber conforms to the gage inspection, the dies are considered dimensionally correct, and
should be lubricated with a THIN coat of any good SAE 20 motor oil. If not, the dies must be replaced before
returning the die assembly to service (see Section 8, DIE REPLACEMENT).
For additional information regarding the use of a plug gage, refer to Instruction Sheet 408-7424.
6. RATCHET (CRIMP HEIGHT) ADJUSTMENT (Figure 7)
The frame assembly ratchet mechanism features an adjustment wheel with numbered settings. If the crimp
height is not acceptable, adjust the ratchet as follows:
1. Remove the lockscrew from the ratchet adjustment wheel.
2. With a screwdriver, adjust the ratchet wheel from the opposite side of the frame.
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 crimp height is acceptable, secure the
lockscrew. If the dimension is unacceptable, remove lockscrew and continue to adjust the ratchet, and
again measure a sample crimp.
Figure 7
7. 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.
