4. DAILY MAINTENANCE
Remove all foreign particles with a clean, soft brush
or clean, soft, lint–free cloth. If foreign matter cannot
be removed easily, or it the proper replacement parts
are not available, return the dies to your supervisor.
Make certain the dies are protected with a thin coat of
any good SAE No. 20 motor oil. DO NOT OIL
EXCESSIVELY. When the dies are not in use, store
them in a clean, dry area.
5. MAINTENANCE AND INSPECTION
5.1. Die Certification
These instructions have been approved by Tyco
Electronics Design, Production, and Quality Control
Engineers to provide documented maintenance and
inspection procedures. Through Tyco Electronics test
laboratories and the inspection of production
assembly, the procedures described herein have
been established to ensure the quality and reliability
of the crimping dies.
5.2. Inspection Procedures
A. Daily Maintenance
It is recommended that each operator of the dies be
made aware of, and responsible for, the following
three steps of daily maintenance:
S Remove dust, moisture, and other
contaminants with a clean brush, or a soft,
lint–free cloth. Do NOT use objects that could
damage the dies.
S Make certain the dies are protected with a
THIN coat of any good No. 20 motor oil. DO
NOT OIL EXCESSIVELY.
S When the dies are not in use, mate and store
them in a clean, dry area.
B. Periodic Inspection
Regular inspections should be performed by quality
control personnel. A record of scheduled inspections
should remain with the dies and/or be supplied to
supervisory personnel responsible for the dies.
Though recommendations call for at least one
inspection a month, the inspection frequency should
be based on the amount of use, ambient working
conditions, operator training and skill, and established
company standards. These inspections should be
performed in the following sequence:
(a) Visual Inspection
1. Remove all lubrication and accumulated film by
immersing the dies in a suitable commercial
degreaser that will not affect paint or plastic
material.
2. Check all bearing surfaces for wear.
3. Inspect the crimp area for flattened, chipped,
cracked, worn, or broken areas. If damage is
evident, the dies must be replaced.
(b) Gaging the Crimping Chamber
This inspection requires the use of a GO NO–GO
Gage conforming to the diameters in Figure 4. Tyco
Electronics does not manufacture or market these
gages.

Figure 4
Select die crimping chamber according to wire size
and proceed as follows:
1. Mate the dies until it is evident that they have
bottomed.
2. Align the GO element with the wire barrel
crimping chamber. Push element straight into the
crimping chamber without using force. The GO
element must pass completely through the
crimping chamber as shown in Figure 4.
3. Now 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 as shown in Figure 4.
If the crimping chamber conforms to the gage
inspection, the dies are considered dimensionally
correct and should be lubricated with a THIN coat of
SAE No. 20 motor oil. If not, the dies must be
replaced.
