Detailed assembly instructions  for  items  source  coded  to  be  assembled from  component  spare/repair  parts  are  found  in  TM 9-2320-273-20   and   TM   9-2320-273-34.   Items   that make up the assembly are listed immediately following the   assembly   entry   or   reference   is   made   to   an applicable  figure. d.   KITS.   Line   item   entries   for   repair   parts   kits appear in group 9401 in Section Il. e. //VDEX  NUMBERS.  Items which have the word BULK  in  the  figure  column  will  have  an  index  number shown in the item number column. This index number is   a   cross-reference   between   the   National   Stock Number/Part Number Index and the bulk material list in Section Il. f. ASSOCIATED PUBLICATIONS. The publications listed below pertain to the Truck, Tractor, Truck Chassis and its components: Publication TM  9-2320-273-20 TM  9-2320-273-34 TM 9-2320-273-34P LO 9-2320-273-12 TM 9-28 15-222-34&P TM 5-3895-371-10 TM 5-3895-271- 10-HR TM 5-3895-271-24&P LO 5-3895-271-12 TM 5-3895-372-10 TM 5-3895-372- 10-HR Short Title Truck, Tractor, Truck Chassis Truck,  Tractor Tuck Chassis Truck,  Tractor Truck  Chassis Truck,  Tractor Truck  Chassis Engine, Diesel Model  NTC-400 Bituminous Distributor M918 Bituminous Distributor M918 Bituminous Distributor M918 Bituminous Distributor M918 Concrete-Mixer,  M919 Concrete-Mixer,  M919 TM  5-3895-372-20 Concrete-Mixer,  M919 TM 5-3895-372-34 Concrete-Mixer,  M919 TM  5-3895-372-34P Concrete-Mixer,  M919 LO  5-3895-372-12 Concrete-Mixer,  M919 6.   How   to   Locate   Repair   Parts. a. 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 use the Figure and Item Number Index to find the NSN. b. When National Stock Number or Part Number is Known: (1) First. Using  the  National  Stock  Number  or the   Part   Number   Index,   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.   Turn   to   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. 7.  Abbreviations.
