7. Tighten the die holding screw while the moving die is bottomed, then complete the crimping cycle.
8. Remove the terminal from the dies, and check the insulation grip by bending the wire back and forth
once. The terminal should retain the grip on the wire insulation. If the wire pulls out, set the insulation
crimp adjustment to the next position as follows:
a. Remove the moving die from the tool.
b. Turn the bottom insulation adjustment spacer 90 degrees so that it fits between the moving die and
the moving die holder for position 2—medium. For position 1—tight, place both adjustment spacers
between the moving die and the moving die holder.
c. Repeat the test crimp, and adjust as necessary until the desired insulation crimp grip is obtained.
5. MAINTENANCE AND INSPECTION
Frequency of an inspection depends on: (1) the care, amount of use, and handling of the dies, (2) type and size
of terminal applied, (3) degree of operator skill, (4) presence of abnormal amounts of dust and dirt, and (5)
established standards.
5.1. Cleaning
Do not allow deposits of dirt, grease, and foreign matter to accumulate in the die closure area and on the
bottoming surfaces of the dies. These deposits may prevent the dies from bottoming fully and may also cause
excessive wear in the die closure surfaces, thereby affecting the quality of the crimp. The dies should be wiped
clean frequently with a clean, soft cloth.
5.2. Visual Inspection
Visually inspect the die closure surfaces for broken, chipped, and pitted surfaces. Although dies may gage
within permissible limits, worn or damaged die closure surfaces are objectionable and can affect the quality of
the crimp.
5.3. Die Closure Inspection
Inspect the die closure using two plug gages. Refer to Figure 4 for recommended plug gage design, then
proceed as follows:
1. Remove traces of oil or dirt from the die crimping areas and plug gage members.
2. Turn both insulation adjustment spacers of the moving die so that they fit into the notch in the side of
the die (position 3—loose). See Figure 1.
3. Insert both dies in the tool.
NOTE
Some dies prevent gaging the wire barrel crimping chamber when in the tool. Remove the dies, rotate the locator 180
degrees, and place the dies in a vise using light pressure.
4. When using pneumatic tools, reduce air supply pressure to a range between 103 and 138 kPa [15 and
20 psi]. Actuate the tool to bottom the dies.
When using the hand tool, close the tool handles until the dies bottom. Do not apply additional
pressure to the tool handles.
5. With the dies bottomed, hold the GO member in a straight alignment with the wire barrel crimping
chamber and carefully insert it without forcing it. The GO member must pass completely through the
wire barrel crimping chamber. Do the same with NO-GO member. The NO-GO member may enter
partially, but must not pass completely through the wire barrel crimping chamber. See Figure 4.
6. Re-position the insulation adjustment spacers to position 1.
7. With the dies bottomed, check the insulation barrel crimping chamber using the plug gage in the same
manner as step 5. See Figure 4.
If both crimping chambers meet the plug gage conditions, the dies are dimensionally correct. If either crimping
chamber does not conform, contact TE.
