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

4.1. 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.

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.

Sight holes of butt splices must always face

either the upper or lower die.

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.
