Microfiche editions are issued quarterly. Each
edition reflects current Cog II Publications and Forms.
Section I and Section III reflect information such as
Canceled, No Superseding Item, Superceded By, and
Replaced By.
The Introduction to the Navy Stock List of
Publications and Forms provides detailed information
about the columnar arrangement of the stock list. It also
has the instructions needed to requisition publications
and forms.
Manufacturers’ Instruction Books
Equipment purchased by the Navy has instruction
books or technical manuals from the manufacturer.
NAVSEA assigns publication numbers to these books
so they can be ordered through the supply system. They
are used by operating and maintenance personnel to
help them obtain top perform ante from the equipment.
They include parts lists and detailed drawings and
specifications. You will use them often to help you
accurately identify repair parts that must be adressed.
Figure 4-11 is an example of a parts list for a laundry
tumbler. It was manufactured by American Laundry
Machinery Industries of Cincinnati Ohio. The CAGE
for this company is 02432. If you were looking up the
NSN for a new front cylinder bearing #6207 in the
MCRL, you would find several entries for that part
number. However, none show an CAGE of 02432.
Now, take another look at figure 4-11, and you will see
the initials “SKF” following “cylinder bearing.” This
shows that:
1.
2.
3.
The tumbler was manufactured by American
Laundry.
The bearings were manufactured by SKF
Industries the part number is #6207.
The CAGE for SKF Industries is 52676. You
will find that part number SKF6207 with an
CAGE of 52676, crosses to NIIN 00-516-5490
in the MCRL.
Also, note that the tumbler belt was manufactured
by Browning and a Browning part number is used. So
when using the MCRL, be sure you are looking for the
right part number with an CAGE for the company that
retie the part.
The drawings and specifications will sometimes
help you find a substitute for a needed repair part using
the catalog identification lists.
Assistance from Technical Ratings
Never overlook the assistance available from
people in the technical ratings, and do not hesitate to ask
for help when an identification problem has you
stumped.
You are not required to know symbols or value
codes that are used on electronic parts, but technicians
in the electronic ratings should. It is not your job to
determine if a tolerance of .005 is permissible for a
bearing, or if that bearing requires grease meeting
specification MIL-G-7187 or VV-G-671.
Your job is to use the information provided by
customers so you can translate their requirements into
the right NSN. When you need more information or are
in doubt about the NSN, ask the expert. It is better to
ask and be sure than to guess and be wrong.
Assistance Ashore
When your efforts to find the NSN for a part have
failed, there are still sources of assistance available to
help. Supply centers and the supply departments of
naval stations and shipyards have technical sections that
can usually provide an NSN if there is one. You should
not depend on them to do your work, but they are
available to assist when needed.
ALLOWANCE LISTS
Allowance lists specify the type and quantity of
equipment, equipage, repair parts, and supporting
materials that a ship in commission is required to carry
on board.
COSAL
The Coordinated Shipboard Allowance List
(COSAL) is the most used allowance list for
determining repair part NSNs. It contains items
authorized and recommended quantities that should be
on hand and provides descriptive data which associate
a material requirement to an NSN. The use of the
COSAL is described in SPCCINST. 4441.170A.
AVCAL
The Aviation Consolidated Allowance List
(AVCAL) contains a list of items authorized that should
be on hand to support aviation equipment.
