ARMY  TM  5-6675-238-14 MARINE CORPS TM 08839A-14/1 Some  shields  may  be  terminated  with  a wire and terminal lug which is connected to a cable clamp screw. (g) (h) (i) (j) Flare  shield  and  terminate  against  rear  or adapter with RFI ferrule. Slide  grommet,  grommet  ferrule,  and  cable clamp ring against RFI ferrule. Screw cable clamp ring onto adapter. Tighten  screws  securing  cable  clamps  to cables. Secure   backshell   to   retaining   ring   with safety wire. c.    Pin   Removal/Insertion. (1) Tools and Contact Pins. Refer to table 8-9 for correct size and sex contact pin and the cor- rect insertion and removal tools, The contact pins and two types of insertion and removal tools are shown in figure 8-14. Use of wrong insertion or removal tool may damage the connector beyond repair. (2) Removal. NOTE Bent  pins  must  be  straightened  before removal. (a) Clip removal tool around wire connected to pin to be removed. See figure 8-15. (b)  Slide  tool  down  wire  until  it  enters  the connector grommet. (c)  Carefully  work  the  tool  over  the  contact barrel until it hits the contact shoulder, (d)  Simultaneously  pull  the  tool  and  wire  out the rear of the connector. (e) Disengage the tool from the contact pin. (3) Insertion. (a) (b) (c) Clip  insertion  tool  around  wire  and  slide tool  against  contact  shoulder.  See  figure 8-16, view A. Guide the contact into the correctly num- bered grommet hole in the rear face of the insert and feed the contact carefully into the hole. See figure 8-16, view B. Push the tool straight in at right angles to the grommet surface until contact is fully seated  and  you  feel  the  contact  retention clip snap into place on the contact with a slight  audible  click. Do not attempt to reseat a contact once the insertion tool has been removed. Re- move contact and start over again. (d) Withdraw the tool, keeping it perpendicular to the grommet face. Check the contact by pulling on wire lightly to assure contact is firmly  locked. d. Crimping  Tool  Operation. (1)  General.   Two  types  of  crimping  tools  and positioners are used depending on contact pin size. (See figures 8-17 and 8-18,) Refer to table 8-9 for the correct contact size, crimping tool, and  positioner. (2) Crimping Tool   MS3198-1, Positioner MS3198-6P    Assembly. NOTE The  tool  handle  must  be  fully  opened when inserting the positioner, and when changing  the  selector  position. (a) To install the positioner, place positioner in bayonet socket at the back of the tool. (b)  Push  positioner  in  and  rotate  90  degrees clockwise  until  locked  in  position. (3) Crimping Tool    MS9191-4, Positioner MS3191-9T    Assembly. NOTE The  tool  handle  must  be  fully  opened when inserting the positioner and when changing  the  selector  position. (a) (b) (c) (d) (e) To install the positioner, press the trigger to release turret to the indexing position. Position  the  positioner  over  the  retaining ring on the back of the tool. Make certain the  positioner  is  seated  on  the  tool;  then secure   the   9/64-inch   sockethead   screws with a sockethead screw key. Turret should now  index  easily  without  binding. Press trigger and spring-loaded turret will snap  out  to  indexing  position. The  turret  has  three  positions  which  are color coded and marked with the applicable contact   size.   Rotate   the   turret   until   the correct position is lined up with the index mark on the positioner, Push the turret into the positioner until it snaps  into  the  locked  position. (4) Crimping.  See  figure  8-19  and  perform  crimp- ing  operation  as  follows: 8-110
