MAINTENANCE AND INSPECTION
The die assembly is thoroughly inspected prior to shipment. Because of the possibility of damage in transit,
dies should be inspected upon arrival in accordance with the information provided, and at regularly scheduled
intervals thereafter to ensure conformance to standards.
6.1.
Maintenance
1. The dies are coated with a preservative to prevent rust and corrosion. Wipe preservative from dies,
particularly from crimping areas, prior to use.
2. Do not allow dirt, grease, or other contaminants to accumulate on the die closure surfaces. These
accumulations may cause excessive wear in the die closure surfaces; thereby affecting the quality of
the crimp.
3. Wipe dies frequently with a clean, soft cloth, and store them in a clean, dry area when not in use.
6.2.
Visual Inspection
Visually inspect the die closure surfaces for broken, pitted, or chipped areas. Although dies may close within
permissible gage limits, worn or damaged die closure surface are objectionable and may affect the quality of
the crimp. Examples of possible damaged die closure surfaces are shown in Figure 9.

Gaging the Crimping Chamber
This inspection requires the use of plug gages conforming to the dimensions provided in Figure 11.
NOTE
TE Connectivity (TE) does not manufacture or market these gages.
To gage the crimping chamber, proceed as follows:
1. Remove traces of oil or dirt from the crimping chamber and plug gage.
NOTE
The
ejector must be removed from the die when gaging a dual-crimp die assembly.
2. Mate the dies, then adjust them to meet the gage dimension indicated in Figure 10. Hold the dies in
this position.
3. Insert GO element into the crimping chamber, but DO NOT force it.
The GO element must pass
through the length of the crimping chamber
(see Figure 10).
4. In the same manner, try to insert the NO-GO element into the crimping chamber.
The NO-GO
element may enter partially, but must not pass completely thru
the length of the crimping
chamber (see Figure 10).
