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
Part Number Index, find the pertinent National Stock
Number or Part Number.
The NSN index is in National
Item Identification Number (NIIN) sequence (see
paragraph 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.
(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.
