3. Jog the power unit to advance the ram to hold the splice in place. Make sure not to deform the wire barrel; otherwise, it may
be difficult to insert the wire into the wire barrel of the splice.
4. Insert the properly stripped wire fully into 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.
5. Holding the wire in place, activate the power unit to complete the other wire barrel crimp.
6. When the wire barrel crimp is completed, remove the crimping head pin, open yoke, and remove the splice.
7. 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).
5. CRIMP INSPECTION
Refer to Application Specification 114-2134 for detailed criteria to check that crimp is applied properly.
The crimp inspection mark (created by the die assembly) on the terminal or splice can be used as a visual
indicator of an acceptable termination, but it does not indicate that the crimp is not acceptable. If the crimp
inspection mark is centered in the crimp area and is evenly and distinctly formed, the crimp is considered
properly applied; however, if it is not:
— refer to Table 2 to verify that the proper terminal or splice and die combination according to the wire
size was used,
— verify that the dies fully bottom during the crimp cycle, and
— ensure that the die assembly is dimensionally correct as specified in paragraph 6.2
