4. MAINTENANCE AND INSPECTION PROCEDURES
Dies for the 69099 Tool
TE Connectivity recommends that a maintenance and
inspection program be performed periodically to
ensure dependable and uniform terminations. Dies
should be inspected at least once a month.
Frequency of inspection may be adjusted to suit your
requirements through experience. Frequency of
inspection is dependent upon:
S The care, amount of use, and handling of the
dies.
S The type and size of the products crimped.
S The degree of operator skill.
S The presence of abnormal amount of dust and
dirt.
S Your own established standards.
Since there is a possibility of die damage in shipment,
new dies should be inspected in accordance with the
following instructions when received in your plant.
1. Clean oil and dirt from the die closure surfaces
and plug gage members.
2. Assemble and adjust the dies to meet the “gage
dimension” indicated in Figure 10, Detail “A”.
3. With the crimping dies assembled as described
in steps 1 and 2, check the wire barrel crimp die
closure using the proper plug gage. Hold gage in
straight alignment with the die closure and carefully
try to inset them without forcing the GO member
as shown in Figure 10, Detail “A”. The GO member
must pass completely through the die closure as
shown in Figure 10, Detail “B”.
4. Try to insert the NO--GO member. The NO--GO
member may enter partially, but must not pass
completely through the die closure. See Figure 10,
Detail “B”.
4.1. Cleaning
Do not allow deposits of dirt, grease, and foreign
matter to accumulate in the die closure surfaces and
on the bottoming surfaces of the dies. These deposits
may prevent the dies from bottoming fully and may
also cause excessive wear in the die closure
surfaces, thereby affecting the quality of the crimp.
The dies should be wiped clean frequently with a
clean cloth.
4.2. Visual Inspection
Visually inspect the die closure surfaces for broken,
pitted, or chipped areas. Although dies may gage
within possible limits, worn or damaged die closure
surfaces are objectionable and can affect the quality
of the crimp. Examples of possible damaged die
closure surfaces are shown in Figure 8.
5. If the dies meet the GO NO--GO gage
conditions, the dies may be considered
dimensionally correct. If you find that the dies no
not conform with the GO NO--GO gage conditions,
contact your local TE Field Representative.

4.3. Die Closure Inspection
Every die set is inspected for proper die closure
before packaging. An inspection should be performed
periodically to check the die closure for excessive
wear. The die closure inspection is accomplished
using the GO NO--GO plug gage. TE neither
manufactures nor sells plug gages. A suggested plug
gage design and the GO NO--GO dimensions of the
plug gage members are listed in Figure 9. The
following procedure is recommended for inspecting
the die closure.

1. Clean oil and dirt from the die closure surfaces
and plug gage members.
2. Assemble the dies so that they are bottomed
but not under pressure. See Figure 10, Detail “A”.
