C
3,56 (.140)
2. Place shrink tubing, crimp ferrule and retaining nut on cable. Flare the cable outer conductor as
shown.
3. Insert cable dielectric into rear body until it bottoms firmly against insulator as shown.
4. Place a 0,38 (.015) dia x 2,50 ± 0,51 (.100 ± .020) long solder wire into solder hole of the center
contact. Heat center contact and push it over cable inner conductor until it bottoms against
insulator as shown. Remove excess solder if necessary.

5. Insert rear body into front body. Engage threads of retaining nut to front body and hand tighten
retaining nut. Hold front body firmly with a 7,93 (.312) hex. torque wrench and torque it to 1,13-1,69
Nm (10-15 in. lbs.). by turning retaining nut only.
6. Slide crimp ferrule over flared portion of cable outer conductor. Crimp outer sleeve in place as
shown. Push cable firmly toward connector when crimping. Trim and remove any excess outer
conductor strands if necessary. Position shrink tubing over crimp sleeve apply indirect heat to
shrink tubing down.
