APPENDIX  C REPAIR  LIST  FOR  ORGANIZATIONAL MAINTENANCE Section   I.   INTRODUCTION C-1.   Scope a.  This   appendix   lists   repair   parts,   special tools,   test   and   support   equipment   required   for the   performance   of   organizational   maintenance of   the   Filter-Separator. b.  Repair   parts   listed   represent   those   author- ized   for   use   at   indicated   maintenance   levels   and will   be   requisitioned   (on   an   “as   required”   basis until   stockage   is   justified   by   demand   in   accord- ance   with   AR   735-35   or   AR   710-2). C-2.   General This   Repair   Parts   and   Special   Tools   List   is divided   into   the   following   sections: a.  Repair   Parts-Section   II.   A   list,   in   figure and   item   number   sequence,   of   repair   parts   au- thorized   at   the   organizational   level   for   the   per- formance   of   maintenance,   including   those   items which   must   be   removed   for   replacement   of   the authorized  item.  Items,  except  kits  and  sets,  are listed   by   assembly   group   in   top   down   break- down   sequence. b.  Special   Tools,   Test   and   Support   Equip- ment-Section   III.   (Not  A p p l i c a b l e ). c .    F e d e r a l    S t o c k    N u m b e r    a n d    R e f e r e n c e Number   Index-Section   IV.   (Not    Applicable).

Repair  Parts,  Special  Tools  and  Test  Equip- ment  which  are  procured  and  stocked  for insurance purposes because combat or mili- tary  essentiality  of  the  end  item  dictates that  a  minimum  quantity  be  available  in the supply system. Code Explanation M Repair  Parts,  Special  Tools  and  Test  Equip- ment which are not procured or stocked, as such,  in  the  supply  system  but  are  to  be manufactured  at indicated  maintenance levels. A Assemblies which are not procured or stocked as  such,  but  are  made  up  of  two  or  more units.   Such   component   units   carry   indi- vidual stock numbers and descriptions, are procured  and  stocked  separately  and  can be  assembled  to  form  the  required  assem- bly at indicated maintenance levels. X Parts  and  assemblies  that  are  not  procured or   stocked   because   the   failure   rate   is normally  below  that  of  the  applicable  end item  of  component. The  failure  of  such part  or  assembly  should  result  in  retire- ment  of  the  end  item  from  the  supply  sys- tem. X1 Repair   Parts   which   are   not   procured   or stocked. The  requirement  for  such  items will  be  filled  by  the  next  higher  assembly or  component. X2 Repair  Parts,  Special  Tools  and  Test  Equip- ment  which  are  not  stocked  and  have  no foreseen  mortality.  The  indicated  mainte- nance level requiring such repair parts will attempt to obtain the parts through canni- balization  or  salvage,  if  not  obtainable through  cannibalization  or  salvage,  the item  may  be  requisitioned  with  exception data,  from  the  end  item  manager,  for  im- mediate use. G Major  assemblies  that  are  procured  with PEMA  funds  for  initial  issue  only  as  ex- change  assemblies  at  DSU  and  GSU  level. Those assemblies will not be stocked above the  DS  and  GS  level  or  returned  to  depot supply  level. NOTE Cannibalization  or  salvage  may  be  used  as  a source   of   supply   for   any   items   source   coded above  except  those  coded  X1  and  aircraft  sup- port  items  as  restricted  by  AR  700-42. (2)   Maintenance   code   indicates   the   lowest level   of   maintenance   authorized   to   install   the listed   item. Repair   Parts   and   Special   Tools   as- signed   maintenance   code   “C”   may   be   stocked   at the   operator   level   of   maintenance   when   author- ized   by   the   Unit   Commander.   The   maintenance level    codes    are: C-1
