6. CRIMP HEIGHT INSPECTION

Crimp height inspection is performed through the

use of a micrometer with a modified anvil,

commonly referred to as a crimp height comparator.

Tyco Electronics does not market crimp height

comparators. Refer to Instruction Sheet 408-7224

for detailed information on obtaining and using a

crimp height comparator.

Proceed as follows:

1. Refer to Figure 4 and select a wire (maximum

size) for the crimp section.

2. Refer to Section 4, CRIMPING PROCEDURE,

and crimp the contact(s) accordingly.

3. Using a crimp height comparator, measure the

wire barrel crimp height as shown in Figure 4. If

the crimp height conforms to that shown in the

table, the tool is considered dimensionally

correct. If not, the tool must be adjusted. Refer to

Section 7, CRIMP HEIGHT ADJUSTME

1. Remove the lockscrew from the ratchet

adjustment wheel.

2. With a screwdriver, adjust the ratchet wheel

from the locator side of the tool.

3. Observe the ratchet adjustment wheel. If a

tighter crimp is required, rotate the adjustment

wheel COUNTERCLOCKWISE to a higher-

numbered setting. If a looser crimp is required,

rotate the adjustment wheel CLOCKWISE to a

lower-numbered setting.

4. Replace the lockscrew.

5. Make a sample crimp and measure the crimp

height. If the dimension is acceptable, replace

and secure the lockscrew. If the dimension is

unacceptable, continue to adjust the ratchet, and

again measure a sample crimp.

8. MAINTENANCE

Ensure that the tool and dies are clean by wiping them

with a clean, soft cloth. Remove any debris with a

clean, soft brush. Do not use objects that could

damage the tool. When not in use, keep handles

closed to prevent objects from becoming lodged in the

crimping dies, and store in a clean, dry area.

9. VISUAL INSPECTION

The crimping dies should be inspected on a regular

basis to ensure that they have not become worn or

damaged. Inspect the crimp section for flattened,

chipped, worn, or broken areas. If damage or

abnormal wear is evident, the tool must be replaced.

See Section 10, REPLACEMENT.

10. REPLACEMENT

Customer-replaceable parts are shown in Figure 1.

Available separately, PRO-CRIMPER III Hand Tool

Repair Kit 679221-1 includes a replacement nut and a

variety of pins, rings, screws, and springs. If the dies

are damaged or worn excessively, they must be

replaced. Order the repair kit and replaceable parts

through your TE representative, or call 1-800-526-
