5.2. Lubrication
Lubricate all pins, pivot points, and bearing surfaces
with SAE 20 motor oil as follows:
Tools used in daily production - lubricate daily
Tools used daily (occasional) - lubricate weekly
Tools used weekly - lubricate monthly
Wipe excess oil from tool, particularly from crimping
area. Oil transferred from the crimping area onto
certain terminations may affect the electrical
characteristics of an application.
5.3. Periodic Inspection
1. The tool should be immersed (handles
partially closed) in a reliable commercial
degreasing compound to remove accumulated
dirt, grease, and foreign matter.
2. Close tool handles until ratchet releases and
then allow them to open freely. If they do not
open quickly and fully, the spring is defective and
must be replaced. See Section 6,
REPLACEMENT AND REPAIR.
3. Inspect head assembly for worn, cracked, or
broken jaws. Refer to Figure 5. If damage is
evident, return the tool to TE for evaluation and
repair. See Section 6, REPLACEMENT AND
REPAIR.
5.4. Gaging the Crimping Chambers
This inspection requires the use of a plug gage
conforming to the dimensions provided in Figure 6
and Figure
TE does not manufacture or market these gages. To
gage the crimping chambers, proceed as follows:
Remove traces of oil or dirt from the crimping
chambers and plug gage.
4. Close the tool handles until it is evident that
the jaws have bottomed; then hold in this
position. Do NOT force the jaws beyond initial
contact.
5. 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.
6. 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.
The jaws in Tools 49935 and 574573 are not
symmetrically located; make sure that the tool
conforms to the symmetry requirements shown in
Figure 8.
If the crimping chambers conforms to the gage
inspection, the tool is considered dimensionally
correct, and should be lubricated with a THIN coat of
any good SAE 20 motor oil. If not, the tool must be
returned for further evaluation and repair. Refer to
Section 6, REPLACEMENT AND REPAIR.
For additional information regarding the use of a plug
gage, refer to Instruction Sheet 408-7424.
