Inspect crimped terminals or splices by checking the
features described in Figure 5. Use only terminals or
splices that meet the conditions shown in the ACCEPT
column. Terminals and splices displaying the features
shown in the REJECT column can be avoided by
careful use of these instructions and by performing the
maintenance and inspection procedures described in
Paragraphs in 5.2 and 5.3.
5.2. Daily Maintenance
It is recommended that each operator of the dies be
made aware of, and responsible for, the following
steps of daily maintenance:
1. Remove dust, moisture, and other contaminants
from the dies with a clean brush, or a clean, soft,
lint-free cloth. Do NOT use objects that could
damage the dies.
2. If dies are coated with oil or preservative, wipe
clean - particularly in the crimping areas - before
placing them in use.
3. When dies are not in use, make certain all
surfaces are protected with a THIN coat of any good
SAE No. 20 motor oil, and mate and store them in a
clean, dry area.
5.3. Periodic Inspection
Regular inspections should be performed by quality
control personnel. A record of scheduled inspections
should remain with the dies or be made available to
supervisory personnel responsible for the dies.
Though recommendations call for at least a monthly
inspection, the inspection frequency should be based
upon the amount of use, working conditions, operator
training and skill, and established company standards.
These inspections should be performed in the
following sequence:
A. Visual Inspection (Figure 6)
1. Remove all lubrication and accumulated film by
immersing the dies in a suitable degreaser that will
not affect paint or plastic.
1. Check all surfaces for wear. Inspect the crimp
area for flattened, chipped, cracked, worn, or
broken areas. If damage is evident, the die must be
replaced.
B. Gaging the Crimping Chamber (Figures 7 and 8)
The inspection requires the use of a plug gage
conforming to the dimensions in Figure 8. Tyco
Electronics does not manufacture or market these
gages.
Proceed as follows:
1. Mate the dies until it is evident that they have
bottomed. Hold the dies in this position.

2. Align the GO element with the wire barrel
crimping chamber. Push the element straight into
the the crimping chamber without using force. The
GO element must pass completely through the
crimping chamber.
3. Align the NO-GO element and try to insert it
straight into the same crimping chamber. The NO-
GO element may start entry but must not pass
completely through. If the crimping chamber
conforms to the gage inspection, the dies are
considered dimensionally correct. If not, they must
be replaced. For additional information regarding
the use of a plug gage, refer to Instruction Sheet
408-7424.
