5. If a splice is being crimped, repeat Steps 2 to 4
for the other crimp side of the splice.
NOTE
i
If splice cannot be turned for crimping other half,
turn the tool around.
CAUTION
!
Damaged splices should not be used. If a
damaged splice is evident, it should be removed
and replaced with a new one. Splices should not
be reterminated.
5. CRIMP INSPECTION
Inspect crimped terminals and splices by checking to
make sure the splice has been crimped in the center
of the wire barrel.
Poor crimps can be avoided by carefully following the
procedures provided in Section 4, and by following
the tool maintenance procedures provided in your
hand tool instruction sheet.
6. DIE INSPECTION
6.1. Visual Inspection
Inspection of the crimping dies should be made on a
regular basis to ensure that they have not become
worn or damaged. Inspect the crimp sections for
flattened, chipped, worn, or broken areas. If damage
or abnormal wear is evident, the dies must be
replaced.
6.2. Measured Die Opening
The dies will perform properly as long as: (1) the
product specified is correct for the application, (2) the
specified die set is used, (3) the die set has been
measured to ensure that the openings are correct,
and (4) the dies bottoms.
7. CRIMP HEIGHT INSPECTION
This inspection requires the use of plug gages
conforming to the dimensions provided in Figure 3.
Tyco Electronics does not manufacture or market
these gages. To gage the crimping chamber, proceed
as follows:
1. Remove traces of oil or dirt from the crimping
chamber and plug gage.
2. Close the tool handles, or cycle the crimp
tooling until the dies have bottomed. Do NOT force
dies beyond initial contact.
3. 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. See Figure 3.
4. 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 the crimping chamber.
See Figure 3.
If the crimping chamber conforms to the gage
inspection, the dies are considered dimensionally
correct, and should be lubricated with a THIN coat of
any good SAE 20 motor oil. If not, the dies must be
returned to Tyco Electronics for further evaluation.
Refer to Section 7, REPAIR/REPLACEMENT.
For additional information regarding the use of a plug
gage, refer to Tyco Electronics Instruction Sheet
408–7424.
8. REPAIR/REPLACEMENT
If the dies do not meet the GO, NO–GO gage
dimensions provided in Figure 3, the tool and/or dies
are defective and must be replaced.
