C-5. SPECIAL INFORMATION (CONT).
c. INDEX 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.
C-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 para C-4.a.(1)). The part numbers in the Part Number Index are listed in
ascending alphanumeric sequence (see para C-4.b.). Both indexes cross-reference with 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 are
looking for, then locate the item number in the repair parts list for the figure.
