ASSEMBLY   INSTRUCTION.   Detailed  assembly  instructions  for  items  source  coded to   be   assembled   from   component   spare/repair   parts   are   found   in   TM   9-2520-272-34&P.   Items that  make  up  the  assembly  are  listed  immediately  following  the  assembly  item  entry  or reference   is   made   to   an   applicable   figure. d. KITS  Line   item   entries   for   repair   parts   kits   appear   in   a   group   in   Section   11   (see table   of   contents). e. INDEX   NUMBERS.   Not   applicable. f.

When   National   Stock   Number   or   Part   Number   is   Not   Known. (1) First.   Using  the  table  of  contents,  determine  the  assembly  group  or subassembly   group   to   which   the   item   belongs. This   is   necessary   since   figures   are   prepared   for assembly   groups   and   subassembly   groups,   and   listings   are   divided   into   the   same   groups. (2) Second.  Find   the   figure   covering   the   assembly   group   or   subassembly   group to   which   the   item   belongs (3) Third.   Identify  the  item  on  the  figure  and  note  the  item  number. (4) Fourth.   Refer  to  the  Repair  Parts  List  for  the  figure  to  find  the  part number  for  the  item  number  noted  on  the  figure. (5) Fifth.  Refer  to  the  Part  Number  Index  to  find  the  NSN,  if  assigned. b. When   National   Stock   Number   or   Part   Number   is   Known: (1) First.   Using   the   Index   of   National   Stock   Numbers   and   Part   Numbers   find the   pertinent   National   Stock   Number   or   Part   Number. The   NSN   index   is   in   National   Item Identification   Number   (NIIN)   sequence   (see   4a(1)).   The   part   numbers   in   the   Part   Number index   are   listed   in   ascending   alphanumeric   sequence   (see   4.   b).   Both   indexes   cross-reference you  to  the  illustration  figure  and  item  number  of  the  item  you  are  looking  for. (2) Second.  After   finding   the   figure   and   item   number,   verify   that   the   item   is the  one  you’re  looking  for;  then  locate  the  item  number  in  the  repair  parts  list  for  the  figure.
