408-1634 Datasheet, PDF (3/6 Pages) Tyco Electronics – Read these instructions and referenced documents before crimping any splices

Die Assemblies 45218, 45221, 69303- 2, and 69820
408- 1634
Setting 1—Tight
Turn both insulation adjustment spacers until the “1” (stamped on
the die) is visible at the beveled corner of the spacers. When
installed into the tool, the L- shaped edge of the spacers will fit
between the die and the tool.
Setting 2—Medium
Turn the insulation adjustment spacer closest to the die until the
“2” (stamped on the die) is visible at the beveled corner of the
spacer. When installed into the tool, the L- shaped edge of the
spacer will fit between the die and the tool.
Setting 3—Loose
Turn both insulation adjustment spacers until the “3” (stamped on
the die) is visible at the beveled corner of the spacers. The
L- shaped edge of the spacer will fit into the notch in the side of
the die.

2. Make sure that the proper screws and retaining
rings are in place and are secured. Check die
alignment and tighten screws (twice daily is
recommended for production use).
3. Make certain that the dies are protected with a
thin coat of any good SAE 20 motor oil. DO NOT
oil excessively.
4. When dies are not in use, mate them and store
them in a clean, dry area.
6.2. Periodic Inspection
Regular inspections should be performed by quality
control personnel with a record of scheduled
inspection remaining with the die assembly or
supplied to personnel responsible for them. Though
recommendations call for at least one inspection per
month, inspection frequency should be based upon
amount of use, working conditions, operator training
and skill, and established company standards. The
inspections should be performed in the following
sequence.

1. Remove all lubrication and accumulated film by
immersing the dies in a suitable commercial
degreaser that will not affect paint or plastic
material.
Figure 5
3. Tighten the die screw. Install die into tool.
4. Perform a test crimp following the steps in
Section 4, and inspect the splice insulation. If the
crimp cuts into, or otherwise damages, the
insulation, start with Step 1 and set the insulation
crimp adjustment to the next setting (Setting 2, as
described in Figure 5). Perform another test crimp.
If the crimp does not meet requirements, set the
adjustment to Setting 3. If the crimp meets
requirements, the adjustment is properly set.
6. MAINTENANCE AND INSPECTION
6.1. Daily Maintenance
It is recommended that each operator of the die
assembly be made aware of, and responsible for, the
following steps of daily maintenance:
1. Remove all foreign particles from the dies with a
clean, soft brush, or a clean, soft, lint--free cloth.
Do not use objects that could damage the dies.

2. Make sure that screws, retaining rings, and die
components are in place.
3. Check all bearing surfaces for wear. Replace
worn components.
4. Inspect the crimping chamber for flattened,
chipped, cracked, worn, or broken areas. If
damage is evident, the dies must be repaired
before returning them to service.
6.3. Gaging the Crimping Chamber
This inspection requires the use of plug gages
conforming to the dimensions provided in Figure 6.
To gage the crimping chamber, proceed as follows:
1. Remove traces of oil or dirt from the crimping
chamber and plug gage.
2. For pneumatic tools, reduce air supply pressure
on tool to between 103 and 138 kPa [15 and
20 psi]. Actuate tool until dies bottom. For manual
tools, close handles until dies bottom. 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 7.
