A. Wire Barrel Crimp Die Closure
1. Clean oil or dirt from the die closure surfaces,
bottoming surfaces, and plug gage elements.
2. Assemble dies so that wire barrel dies are
bottomed but not under pressure.
3. With wire barrel dies bottomed, inspect the wire
barrel crimp die closure using the proper plug gage.
Hold gage in straight alignment with the die closure
and carefully insert, without forcing, the GO
element. See Figure 6A. The GO element must
pass completely through the wire barrel crimp die
closure.
4. Try to insert the NO-GO element. The NO-GO
element may enter partially, but must not pass
completely through the wire barrel crimp die
closure. See Figure 6A.
B. Insulation Crimp Die Closure
1. With wire barrel dies bottomed and not under
pressure, set insulation crimp dies at “gage”
dimension shown in Figure 6B.
2. Inspect the insulation crimp die closure using the
proper plug gage in the same manner as steps (c)
and (d) in paragraph 4.3.A. See Figure 6B.
If both the wire barrel and insulation crimp die
closures meet the GO NO-GO gage conditions, the
dies may be considered dimensionally correct.
