5. MAINTENANCE AND INSPECTION
A maintenance and inspection program should be
performed periodically. It is recommended that initial
frequency of inspection be performed once a month.
The frequency of an inspection is dependent upon:
Die assemblies are thoroughly inspected before being
shipped; however, since there is a possibility of die
damage during shipment, it is recommended that dies
be inspected by following Section 3 when received.
5.1. Cleaning
Do not allow deposits of dirt, grease, and foreign
matter to accumulate in the die closure area 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, soft cloth.
5.2. Visual Inspection
Visually inspect the die closure surfaces for broken,
chipped, or pitted conditions. Although dies may gage
within permissible limits, worn or damaged die closure
surfaces are objectionable and can affect the quality
of the crimp. Examples of possible damaged die
surfaces are shown in Figure 9.
5.3. Gaging the Crimping Chamber
This inspection requires the use of plug gages
conforming to the dimensions provided in Figure 10.
To gage the crimping chamber, proceed as follows:

Terminal and Splice Crimping Die Assemblies
3. Use Position 1 for wire having a small insulation
diameter. Turn both insulation adjustment spacers
so that they will fit between the moving die and the
die holder. No. 1 will appear on the corner of the
top spacer nearest the color dot code.
— the care, amount of use, and handling of the
dies,
— type and size of the products applied,
— degree of operator skill,
— presence of abnormal amounts of dust and dirt,
and
— your own established standards.
1. Remove traces of oil or dirt from the crimping
chamber and plug gage members.
2. Turn both insulation adjustment spacers of the
moving die so that they fit into the notch in the side
of the die. See Figure 1. The die is now set in the
Position 3 (loose). This will provide access to the
wire barrel section of the crimping chamber for
plug gaging.

CAUTION
3. Insert both dies in the tool die holders.
4. For the hand tool, close the handles of the tool
until the dies bottom. DO NOT apply additional
pressure to the tool handles. Actuate the tool until
the dies bottom.
5. If the position of the locator and the insulation
barrel section of the crimping chamber prevent
gaging the wire barrel section of the crimping
chamber, remove the die assembly from the hand
tool, and rotate the locator 180 _ . This will allow
access to the wire barrel section. The die assembly
can then be placed in a vise (using light pressure)
for gaging.
6. With the wire barrel crimping section of the dies
bottomed, check the wire barrel section using the
proper plug gage. Hold the gage in a straight
alignment with the crimping chamber and carefully
try to insert, without forcing the GO member, and
then the NO–GO member. See Figure 12, Detail A.
The GO member must pass completely through
the crimping chamber.
7. The NO–GO member may enter partially, but
must not pass completely through the wire barrel
section of the crimping chamber. See Figure 12,
Detail A.
8. Remove the moving die from the tool die holder.
9. Reposition the insulation adjustment spacers in
the No. 1 position. Refer to Paragraph 2.4 for
insulation crimp position adjustment procedures.
10. Insert the moving die into the tool die holder.
11. With the wire barrel crimping section of the
dies bottomed, check the insulation barrel section
of the crimping chamber using the proper plug
gage in the same manner as steps 6 and 7. See
Figure 12, Detail B.

If using a pneumatic tool, reduce the air supply
pressure to a range between 15 and 20 psi
[103.4 and 137.9 kpa] before actuating the tool.
