408-6775 Datasheet, PDF (2/4 Pages) Tyco Electronics – Install dies according to the instructions packaged with the tooling.

3.2. Ferrule
1. Slide the ferrule over the cable braid and
contact support sleeve until the ferrule bottoms
against the contact body.
2. Insert contact body through the ferrule
crimping chamber from the FRONT of the tool.
Make sure that the shoulder on the ferrule is
against the edge of the ferrule crimping
chamber. See Figure 3.

4. MAINTENANCE AND INSPECTION
The die assembly is inspected before shipment. Tyco
Electronics recommends that the die assembly be
inspected immediately upon arrival at your facility to
ensure that the die assembly was not damaged
during shipment and that it conforms to the
dimensions provided in Figure 4.
4.1. Daily Maintenance
Tyco Electronics recommends that each operator of
the dies be made aware of—and responsible for—the
following four steps of daily maintenance:
1. Remove dust, moisture, and other
contaminants with a clean brush or a soft, lint–
free cloth. Do NOT use objects that could
damage the dies.
2. Make sure the proper screws are in place and
secured.
408-6775
3. Make certain all surfaces are protected with a
THIN coat of any good SAE 20 motor oil. Do
NOT oil excessively.
When the dies are not in use, store them in a clean,
dry area.
4.2. Periodic Inspection
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. The
inspection frequency should be based on the amount
of use, working conditions, operator training and skill,
and established company standards. These
inspections should be performed in the following
sequence:
A. Visual Inspection
1. Remove all lubrication and accumulated film
by immersing the dies in a suitable commercial
degreaser that will not affect paint or plastic
material.
2. Make certain all screws, retaining rings, and
die components are in place. If replacements are
necessary, refer to parts listed in Figure 5.
3. Check all bearing surfaces for wear. Remove
and replace worn components.
4.3. Gaging the Crimping Chamber
This inspection requires the use of plug gages
conforming to the dimensions provided in Figure 4.
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. Mate the dies until the crimping surfaces have
bottomed; then hold in this position. Do NOT
force beyond initial contact.
3. Insert GO element into the crimping chamber;
but do not force it. The GO element must pass
completely through the crimping chamber. See
Figure 4.
4. In the same manner, try to insert the NO–GO
element into the crimping chamber. The NO–GO
element may enter partially, but must not pass
completely through the length of the crimping
chamber. See Figure 4.
If the crimping chambers conform to the gage
inspection, the dies may be considered dimensionally
correct and should be lubricated with a THIN coat of
any good SAE 20 motor oil. If the crimping chamber
does NOT conform to the gage inspection, refer to
Section 5 for information on obtaining evaluation and
repair.
