All crimping heads are thoroughly inspected before
packaging. Since there is a possibility of damage in
shipment, new heads should be inspected in
accordance with the following instructions when
received in your plant.
4.1. Cleaning
Chipped
Broken
Pitted
CAUTION
!
Do NOT allow deposits of dirt, grease, and
foreign matter to accumulate on the jaw
bottoming surfaces and die closure surfaces.
These deposits may cause excessive wear,
thereby affecting the quality of the crimp.
The crimping head should be immersed in a reliable
commercial de–greasing compound to remove
accumulated dirt, grease, and foreign matter. Remove
remaining de–greasing compound with a lint–free
cloth. When de–greasing compounds are not
available, head may be wiped clean with a lint–free
cloth. Re–lubricate head as instructed in Paragraph
4.3, before placing it back in service.
4.2. Visual Inspection
A. Visually inspect the crimping head for missing pins
or retaining rings. If parts are missing or defective,
refer to Figure 10 for customer replaceable parts.
B. Inspect the die closure surfaces of the head for
broken, pitted, or chipped conditions. Although dies
may gage within permissible limits, worn or damaged
die closure surfaces are objectionable and can affect
the quality of the crimp. Examples of possible
damaged die closure surfaces are shown in Figure 6.
4.3. Lubrication
Lubricate all pins, pivot points, and bearing surfaces
with a good grade S.A.E. no. 20 motor oil as follows:
Heads used in daily production – Lubricate daily
Heads used daily (occasional) – Lubricate weekly
Heads used weekly – Lubricate monthly
Wipe excess oil from head, particularly from crimping
area. Oil transferred from the crimping area onto
certain terminations may affect the electrical
characteristics of an application.

4.4. Die Closure Inspection
Every crimping head is inspected for proper die
closure before packaging. An inspection should be
performed periodically to check the die closure for
excessive wear. The die closure inspection is
accomplished using GO/NO–GO plug gages. Tyco
Electronics neither manufactures nor sells plug
gages. A suggested plug gage design and the
GO/NO–GO dimensions of the plug gage members
are listed in Figures 7 and 8. The following procedure
is recommended for inspecting the die closures.
1. Clean oil or dirt from die closure surfaces,
bottoming surfaces, and plug gage members.
2. Select the proper GO gage. Position gage
member in lower jaw inner crimp closure so that
locator is in notch of gage member. See Figure 9,
Detail A.
3. Close the crimping jaws until they are bottomed
but not under pressure.
4. To meet the GO gage conditions, the plug gage
must be able to be rotated freely in either direction
as shown in Figure 9, Detail A.
5. Select the proper NO–GO gage. Position gage
member in lower jaw inner crimp closure so that
locator is in notch of gage member. See Figure 9,
Detail B.
6. Close the crimping jaws so that inner crimp
surfaces are seated on the NO–GO gage member.
7. To meet the NO–GO gage conditions, jaw
bottoming surfaces will NOT bottom, and NO–GO
gage member will be held stationary (will not
rotate) by the dies. See Figure 9, Detail B.
8. Inspect the right and left outer crimp closures in
the same manner as steps 4.4.2 thru 4.4.7. See
Figure 9, Details C and D.
