HOW TO LOCATE REPAIR PARTS
When National Stock Number or Part Number is NOT Known:
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.
Second. Find the figure covering the assembly group or subassembly group to which the item belongs.
Third. Identify the item on the figure and use the Figure and Item number index to find the NSN.
When National Stock Number or Part Number is Known:
First. Using the National Stock Number or Part Number Index, find the pertinent National Stock
Number or Part Number. The NSN index is in National Item Identification Number (NIIN) sequence, (see 4 a (1)). The
part numbers in the Part Number index are listed in ascending alphanumeric sequence, (see paragraph 4 b). Both
indexes cross-reference you to the illustration/figure and item number of the item you are looking for.
Second. Turn to 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.
