Plug gage dimensions apply when tool is bottomed, but not under pressure.
Figure 4
To gage die closure, refer to Figure 5 and Figure 6
and proceed as follows:
1. Remove traces of oil or dirt from the crimping
chambers and plug gage.
2. Open tool crimping jaws and insert the GO
element of the proper wire barrel plug gage into the
space between the wire barrel die (inner) and the
insulation die (outer). Plug gage may be inserted
from either side of the tool.

3. 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.
4. Align the GO element with the wire barrel
crimping chamber. Push element straight into the
crimping chamber without using force. The GO
element must pass completely through the
crimping chamber.
5. Check the wire barrel crimping chamber with the
NO GO element in the same manner as steps 2
through 4. The NO GO element may start entry,
but must not pass completely through the crimping
chamber.
6. Check both sets of insulation barrel crimping
dies with the proper insulation barrel plug gage in
the same manner as steps 2 through 5.
If both wire barrel and insulation barrel crimping dies
conform to the gage inspection, the crimping
chambers are considered dimensionally correct. If
correct, the tool should be lubricated with a thin coat
of any good SAE No. 20 motor oil and returned to
service. If not correct, the tool must be returned to
Tyco Electronics for further evaluation and repair.
Refer to Section 5, REPLACEMENT AND REPAIR.
For additional information regarding the use of a plug
gage, refer to Instruction Sheet 408–7424.
