4. Insert the properly stripped wire fully into the wire barrel of the terminal. Ensure that there are no
exposed strands.
CAUTION
DO NOT turn or twist the wire or terminal during wire insertion; otherwise, the internal screen of the terminal could turn and cut
into the wires during crimping.
5. Holding the wire in place and fully inserted, activate the power unit to complete the crimp.
6. Remove the crimped terminal from the die assembly. When removing a terminal from the die
assembly, grip it as shown in Figure 4.
NOTE
If terminal sticks in die after crimping, apply a rocking action to free it. Wipe light oil or use spray dry lubricant on dies to
prevent sticking.
4.2. Splice
IMPORTANT: To ensure a quality crimp, gage the die assembly at the beginning of a run, after changing a die
assembly — and then periodically during the run. Refer to Paragraph 6.2 for gaging instructions.
The preferred method is:
1. Before each crimp, apply a spray dry lubricant to the crimping area of the dies to reduce sticking of the splice in the dies.
2. Insert the properly stripped wire fully into the wire barrel of the splice. When crimping a splice with a color-coded band, insert
the correct copper wires into the color-coded banded end of the splice. Ensure that there are no exposed strands.
CAUTION
DO NOT turn or twist the wire or splice during wire insertion; otherwise, the internal screen of the splice could turn and cut into
the wires during crimping.
3. Position the splice in the stationary die (nest) so that edge of the die is within the width of the circumferential crimp alignment
mark of the splice. The asterisk alignment mark on the splice must be inside the die, facing up, and in alignment with the
alignment dot of the die. See Figure 5.
NOTE
Make sure that the splice is properly aligned in the stationary die (nest) so that the moving die (anvil) will crimp the wire barrel
of the splice.
4. Holding the wire in place, activate the power unit to complete the first wire barrel crimp.
5. When the first wire barrel crimp is completed, remove the crimping head pin, open the yoke, and remove the splice.
6. To crimp the other wire barrel of the splice, rotate the splice or crimping head 180 degrees, and position the splice in the die
so that the asterisk alignment mark on the splice is inside the die, facing up, and in alignment with alignment dot of the die.
See Figure 5. Follow the same steps used to crimp the first wire barrel (Steps 1 through 5).
An alternate method is:
NOTE
This method is only slightly different than the preferred method. The difference is when the wire is inserted into the wire barrel.
1. Before each crimp, apply a spray dry lubricant to the crimping area of the dies to reduce sticking of the splice in the dies.
2. Position the splice in the stationary die (nest) so that edge of the die is within the width of the circumferential crimp alignment
mark of the splice. The asterisk alignment mark on the splice must be inside the die, facing up, and in alignment with the
alignment dot of the die. See Figure 5.
