1. Strip the outer insulation of the wire (Figure A).

OUTER INSULATION
2. Slide the ferrule onto the wire until it stops on outer insulation and
fold braid back over the ferrule (Figure B). Comb braid and make
sure that it covers 50-100% of the smaller portion of the ferrule but
does not reach past the shoulder.

3. Strip center conductor (Figure C).
4. Solder wire center conductor into contact center conductor and
clean (Figure D).
NOTE: Contact center conductor and dielectric must touch
(Figure E).
5. Calibrate the Inspection Depth Gauge, Part # 910 121 180 (Figure
F), by loosening the dial face retaining screw until the dial face
allows itself to be turned. Insert the calibration plug into base of
gauge. While keeping constant pressure on the plug, adjust the
dial by rotating it such that the pointer points to “0”. Re-tighten
retaining screw. Adjust locating markers to “5” and “95”.

SHIELD CONDUCTOR
Slide shield conductor over center conductor until the shield
conductor stops flush (Figure G).
NOTE: Do not twist the shield conductor; twisting will cause the
braid to bunch.
7. Check the .136″ ± .005 dimension (Figure H) by using the inspection
depth gauge. Insert contact into gauge until contact stops.
If pointer measures between “5” and “95”, go to step 8. If the
pointer is out of the range of the two markers, slide the ferrule to
adjust. Repeat steps 1-7, if necessary.
8. Before using the Hex Crimp Tool (Figure J), you must install the
locator (Figure K). Remove the 2 screws using the .050” Allen
wrench and replace the existing locator with the Locator, Part #
910 101 139 (Figure L). Tighten the 2 screws. The tool is now ready to
crimp ITA contacts.

9. Crimp using Hex Crimp Tool Part # 910 101 132 for RG 316 and RG
179, or Hex Crimp Tool Part # 910 101 131 for RG 178 (Figure J). To
ensure proper crimp position, slide shield conductor over pin on
the locator (Figure M).
OBSERVE PRECISION RATCHET ACTION BY OPENING
AND CLOSING CRIMP TOOL FULLY SEVERAL TIMES. THE
TOOL CANNOT BE OPENED WITHOUT COMPLETING A
CYCLE. NEVER ATTEMPT TO DISASSEMBLE TOOL. NEVER
TIGHTEN OR LOOSEN STOP NUTS ON BACK OF TOOL.

Wire must not be allowed to pull on the center conductor during
crimping (for example, long wire hanging down to floor). Ensure
outer shield is flush with ferrule after crimping (Figure N).
10. Use the inspection depth gauge to verify the .136″ ± .005
dimension as shown in step 7. If the dimension is out of range,
repeat steps 1-10.
