7.2. Periodic Inspection
A. Lubrication
Lubricate all pins, pivot points, and bearing surfaces
with SAE 20 motor oil as follows:
Tool used in daily production – lubricate daily
Tool used daily (occasional) – lubricate weekly
Tool 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.
B. Visual Inspection
Inspect head assembly for worn, cracked, or broken
jaws. If damage is evident, return the crimping head
to Tyco Electronics for evaluation and repair. See
Section 7, REPLACEMENT AND REPAIR.
C. Crimping Die Closure Inspections
Each crimping head is inspected for proper die
closure before shipment. However, inspection of die
closure for excessive wear is required periodically.
This inspection requires the use of plug gages
conforming to the dimension shown in Figure 5. Tyco
Electronics does not manufacture or market these
gages.
To gage die closure, refer to Figure 6 and proceed as
follows:
1. Remove traces of oil or dirt from the crimping
chamber and plug gage.

Wire Barrel Section of Crimping Chamber
2. Close the tool until the wire barrel dies are
bottomed.
3. With wire barrel dies bottomed, inspect the wire
barrel crimp die closure using the proper plug
gage. Press the spring–loaded locator down and
hold gage in alignment with the die closure.
4. Align the GO element with the wire barrel
section of 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 6.
5. Align the NO–GO element and try to insert it
straight into the same section of the crimping
chamber. The NO–GO element may start entry,
but must not pass completely through the crimping
chamber. See Figure 6.
6. Insert tool insulation crimping adjustment pin
into Position 1.
7. With crimping dies bottomed, check the
insulation barrel section of the crimping chamber
as described in Steps 4 and 5.
If the crimping chamber conforms to the gage
inspection, the crimping head is considered
dimensionally correct, and should be lubricated with a
THIN coat of any good SAE 20 motor oil. If not, the
crimping head must be returned to Tyco Electronics
for further evaluation and repair. Refer to Section 7,
REPLACEMENT AND REPAIR.
For additional information regarding the use of plug
gages, refer to Instruction Sheet 408–7424.
