4.2. Crimping Splices

Avoid personal injury. When operating tool or

power unit, exercise caution while holding splice

or wire near the crimping area.

1. Strip wires to the dimensions listed in Figure 3.

Do not nick or cut the wire strands.

2. Select the proper color–coded splice for the wire

size. The wire size stamped on the splice and on

the crimping die must match the wire size selected.

3. Insert the stripped wire into the wire barrel of the

end of the splice to be crimped until the wire

bottoms against the wire stop within the splice.

4. Place the splice in the stationary die. Grasp the

end of the splice to be crimped and point the

opposite end toward the top of the head yoke at

approximately a 30

_ angle. Rotate the end of the

splice to be crimped into the die. Position the edge

of the window indent against the locator. Refer to

Figure 5.

5. Holding wire in place, activate tool or power unit

to complete first wire barrel crimp.

6. When crimp is completed, remove the latch pin,

open the yoke and remove the splice.

If splice sticks in die after crimping, apply a

rocking action to the splice to remove it from the

die. Wipe light oil on dies to reduce sticking, or

use spray dry lubricant.

7. To crimp the other half of splice, reposition

uncrimped end of splice in the stationary die and

follow the same procedure used to crimp the first

half of splice.

8. Inspect the crimp according to Section 5.

4.3. Crimping Splices With Step-Down Adapter

Avoid personal injury. When operating tool or

power unit, exercise caution while holding splice

or wire near the crimping area.

1. Strip wires to the dimensions listed in Figure 3.

Do not nick or cut the wire strands.

2. Select the proper splice, adapter, and crimping

die for the wire size. See Figure 6. Note that the

end of the splice containing the adapter has a

different color code. Use the crimping die for the

larger wire size to crimp both ends of the splice.

For example, use Crimping Die 1490598–1 (for

wire size 6 AWG) to crimp both ends of the splice

with step–down adapter for stepping down from

wire size 6 to 8 AWG.
