3.2. Die Removal
Ensure that the possibility of accidental activation of
the hydraulic power unit has been eliminated, and
proceed as follows:
1. Depress the upper release button located in the
C--head and slide the nest out of the head.
2. Activate the power unit until the lower die
release button in the ram is exposed.
3. Depress the release button and slide the
indenter out of the ream.
4. WIRE PREPARATION AND CRIMPING PROCEDURES
4.2. Crimping Procedure
1. Ensure that the wire size stamped on the
terminal or splice corresponds to the wire size
stamped on the stationary die.
2. Center the terminal or splice in the stationary die
as shown in Figure 4.
3. Activate the power unit so that the moving die
advances and holds the terminal or splice in place
without deforming the wire barrel.
4. Insert the stripped wire until it bottoms in the
terminal or butt splice. The end of the wire must be
visible through the sight hole.
NOTE
i
Sight holes of butt splices must always face
either the upper or lower die.
4.1. Wire Preparation
1. Select proper size terminal or splice for wire size
being used.
2. Determine correct terminal or splice wire loading
by referring to CMA (Circular Mill Area) range listed
in the table in Figure 1. The total CMA of wires
being used must be within the CMA range of the
terminal or splice.
3. Strip the wire to the dimensions indicated in the
table in Figure 2, taking care not to nick or cut the
wire strands.
5. When inserting the stripped wires into a parallel
splice, the ends of the wires must be at least flush
with, or extend slightly beyond the end of the wire
barrel.
6. Activate the power unit to complete the crimp.
7. To crimp the other half of the butt splice, remove
and reposition the uncrimped half in the stationary
die. Insert the wire until it bottoms against the
splice sire stop (visible through the sight holes),
and then crimp the splice.
8. Inspect the crimp by referring to Section 5,
CRIMP INSPECTION, and to Figure 5.
