2. DESCRIPTION
Each tool consists of a CERTI-CRIMP tool ratchet and two crimping jaws (indenter and anvil) containing one,
two, or three crimping chambers. Each tool is marked with the wire size range for each crimping chamber
(Figure 1). Full crimping of the terminal or splice is assured by the CERTI-CRIMP tool ratchet. When engaged,
the ratchet does not release until the tool handles have been fully closed.
CAUTION
The crimping jaws bottom before the ratchet releases. This feature ensures maximum electrical and tensile performance of
the crimp. Do not re-adjust the ratchet.
3. CRIMPING
1. Strip the wire according to the dimensions listed in Table 1. The strip length is determined by the type
of terminal or splice and by the wire size. Do not nick or cut the wire strands.
2. Close the tool handles until the ratchet releases.
3. Allow the tool handles to open fully.

4. Center the terminal or splice wire barrel in the appropriate crimping chamber (Figure 2).
For terminals, make sure that the flat side of the tongue faces the anvil or the nest.
For splices, make sure that the brazed seam (when visible) is toward the indenter or the nest.

NOTE
Terminals and splices can also be rotated 180 degrees with the seam toward the nest.
5. While holding the terminal or splice in place, squeeze the tool handles together just until the jaws begin
to close on the wire barrel. Do not deform the wire barrel.
6. Insert the stripped wire into the wire barrel, making sure that the wire insulation does not enter the wire
barrel (Figure 3).

8. To crimp the other half of a butt splice, position the uncrimped wire barrel in the crimping chamber and
repeat the crimping procedure.
NOTE
If the splice cannot be turned for crimping the other half, turn the tool around.

4. INSPECTING THE CRIMP
Inspect crimped terminals and splices by checking the features shown in Figure 4. Poor crimps (Figure 5) can
be avoided by carefully following the procedures provided in Section 3, and by following the tool maintenance
procedures provided in Section 5.

5. MAINTENANCE AND INSPECTION
The tool is inspected before being shipped. Inspect it immediately upon arrival at your facility to ensure that the
tool has not been damaged during shipment.
Frequency of inspection depends on:
The care, amount of use, and handling of the hand tool
The presence of abnormal amounts of dust and dirt
The degree of operator skill
Your own established standards
5.1. Daily maintenance
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 or tool.
Make certain that the retaining pins are in place and that they are secured with retaining rings.
All pins, pivot points, and bearing surfaces should be protected with a thin coat of any good SAE 20
motor oil. Do not oil excessively.
When the tool is not in use, keep the handles closed to prevent objects from becoming lodged in the
dies. Store the tool in a clean, dry area.
5.2. Lubrication
Lubricate all pins, pivot points, and bearing surfaces with SAE 20 motor oil as indicated in Table 2.

NOTE
Wipe excess oil from the tool, particularly from the crimping area. Oil transferred from the crimping area onto certain
terminations can affect the electrical characteristics of an application.

5.3. Periodic inspection
Remove accumulated dirt, grease, and foreign matter by immersing the tool (with handles partially
closed) in a reliable commercial degreasing compound.
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 6, REPLACEMENT AND
REPAIR.
Inspect the head assembly for worn, cracked, or broken jaws (Figure 6). If damage is evident, return
the tool to TE for evaluation and repair. See Section 6, REPLACEMENT AND REPAIR.

TE does not manufacture or market these gages. To gage the crimping chambers, proceed as follows:
1. Remove traces of oil or dirt from the crimping chambers and plug gage.
2. Close the tool handles until it is evident that the jaws have bottomed; then hold in this position. Do not
force the jaws beyond initial contact.
3. Align the GO element with the crimping chamber. Push element straight into the crimping chamber
without using force. The GO element must pass completely through the crimping chamber (Figure 8).
4. Align the NO-GO element and try to insert it straight into the same crimping chamber. The NO-GO
element can enter partially, but must not pass completely through the crimping chamber (Figure 8).

NOTE
The jaws in Tools 49935 and 574573 are not symmetrically located. Make sure that the tool conforms to the symmetry
requirements shown in Figure 9.

0.254 mm [.010 in.] minimum (typical)
If the crimping chambers conform 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 for further evaluation and repair. Refer to Section 6, REPLACEMENT
AND REPAIR.
For additional information regarding the use of a plug gage, refer to Instruction Sheet 408-7424.

5.5. Inspecting the ratchet
1. Check the CERTI-CRIMP tool ratchet to verify that the ratchet does not release prematurely, allowing
the jaws to open before they have fully bottomed.
2. Obtain a 0.025 mm [.001 in.] shim suitable for checking the clearance between the bottoming surfaces
of the crimping jaws.
3. Select a terminal or splice, and properly stripped wire with maximum wire load (such as wire size 16
AWG and size 22-16 terminal).
4. Position the terminal or splice and wire between the crimping jaws, as described in Section 3,
CRIMPING.
5. Hold the wire in place and squeeze the handles until the CERTI-CRIMP tool ratchet releases. Hold the
handles in this position, maintaining just enough tension to keep the jaws closed.
6. Use the shim to check the clearance between the bottoming surfaces of the crimping jaws.
If the clearance is 0.025 mm [.001 in.] or less, the ratchet is satisfactory.
If clearance exceeds 0.025 mm [.001 in.], the ratchet is out of adjustment and must be repaired.
See Section 6, REPLACEMENT AND REPAIR.
