5.2. Periodic Inspection
Regular inspection should be performed by quality
control personnel. A record of scheduled inspections
should remain with the tool and/or be supplied to the
supervisory personnel responsible for the tool. 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 visual inspections should be
performed in the following sequence:
1. Remove all lubrication and accumulated film by
immersing the dies in a suitable degreaser that
will not affect paint or plastic material.
2. Make sure all die holding screws and die
components are in place. Refer toe parts listed in
Figure 6 if replacements are necessary.
3. Check all bearing surfaces. Remove and
replace worn components.
4. Inspect the crimp area for flattened, chipped,
cracked, worn or broken areas. If damage is
evident, the dies must be repaired before
returning them to service. Refer to Section 6,
REPAIR.
5.3. Gaging the Crimping Chamber
This inspection requires the use of a plug gage
conforming to the diameters in Figure 5.
TE Connectivity 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 with a
pressure of approximately 69 kPa [10 psi].
2. 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 5.
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, as shown in Figure 5.
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 20 motor oil. If not, the dies must be repaired
before returning them to service.
For additional information concerning the use of a plug
gage, refer to Instruction Sheet 408-7424.
