Each crimping die is thoroughly inspected before
packaging. Since there is a possibility of damage
during shipment, the crimping die should be inspected
immediately upon arrival at your facility.
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.
It is recommended that each operator of the dies be
made aware of—and responsible for—the following
steps of daily maintenance:
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 can affect the quality of the crimp. Examples
of possible damaged die surfaces are shown in
Figure 5.
The die closure inspection is accomplished using plug
gages. A suggested gage design and the GO and
NO–GO diameters of the plug gage elements are
shown in Figure 6. The following procedure is
recommended for inspecting the die closures.
1. Remove dust, dirt, and other contaminants with
a clean brush, or a soft, lint–free cloth. Do NOT
use objects that could damage the dies.
2. Make certain the dies are protected with a THIN
coat of any good SAE 20 motor oil. Do not oil
excessively.
3. When the dies are not in use, mate them and
store in a clean, dry area.
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 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 7.
If the crimping chamber conforms to the gage
inspection, the crimping die is considered
dimensionally correct and should be lubricated with a
THIN coat of SAE 20 motor oil. If not, the dies must
be repaired before returning them to service (see
Section 7, REPLACEMENT AND REPAIR).
For additional information concerning the use of a
plug gage, refer to Instruction Sheet 408–7424.

3. Align the NO–GO element and try to insert it
straight into the crimping chamber. The NO–GO
element may start entry but must not pass
completely through as shown in Figure 7.
