How to Locate Repair Parts
a. When National stock number or part number
is unknown.
(1) First. Using the table of contents,
determine the functional group within which the item
belongs.
This is necessary since illustrations are
prepared for functional groups and listings are divided
into the same groups.
(2) Second. Find the illustration covering
the functional group to which the item belongs.
(3) Third.
Identify the item on the
illustration and note the illustration figure and item
number of the item.
(4) Fourth. Using the Repair Parts Listing,
find the figure and item number noted on the illustration.
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. This index is in NIIN
sequence followed by a list of part numbers in
alphameric sequence, cross-referenced to the illustration
figure number and item number.
(2) Second. After finding the figure and
item number, locate the figure and item number in the
repair parts list.

This fine document...
Was brought to you by me:
Liberated Manuals -- free army and government manuals
Why do I do it? I am tired of sleazy CD-ROM sellers, who take publicly
available information, slap “watermarks” and other junk on it, and sell it.
Those masters of search engine manipulation make sure that their sites that
sell free information, come up first in search engines. They did not create it...
They did not even scan it... Why should they get your money? Why are not
letting you give those free manuals to your friends?
I am setting this document FREE. This document was made by the US
Government and is NOT protected by Copyright. Feel free to share,
republish, sell and so on.
I am not asking you for donations, fees or handouts. If you can, please
provide a link to liberatedmanuals.com, so that free manuals come up first in
search engines:
