CATEGORIES OF MAINTENANCE

2 1. General

2 4. Packaging and Packing Materials

There are three major levels of maintenance in

which Army personnel involved are responsible.

These maintenance responsibilities are as re-

quired in the DA TMs, related publications and

regulations. These levels of maintenance are

detailed in the Maintenance Allocation Chart

MAC) published in the Organizational Mainte-

nance TM for specific materiel. The levels of

maintenance ar e briefly described below in para-

graphs 2-3 throug h 2-5.

2 2. Organizational Maintenance

Organizational maintenance is performed by all

activities having conventional ammunition on

hand including using units. It is performed to

prevent deterioration of ammunition due t o rough

handling and exposure. Organizational unit s may

call upon DS units for technical advice and

assistance. Organizational maintenance involves

cleaning, removal of minor rust and corrosion,

repair and replacement of boxes, and restenciling

of con tainers as prescribed in -10, -12, or -20 TM as

required by MAC published therein.

2 3. Direct Support Maintenance

DS maintenance is performed by conventional

ammunition companies an d includes surveillance

and limited maintenance of stocks under their

control. Ammunition companies assume more

responsibility for maintenance when opera ting in

a rear, semipermanent installation where time,

equipment, and personnel are usually readily

available. Maintenance operations at ammunition

supply points ASP) are performed on a job lot

rat her th an a n assembly line basis. Maintenance

performed consists of, but is not limited to, the

following:

a.

Cleaning and protection of individual items

andlor packing material.

b

Removal of light rust.

c

Minor repai r

of

boxes, containers, and crates.

d.

Spot paintin g and restenciling.

e. Replacement of readily removable external

part s and components such as, but not limited to,

fuzes of artil lery and mort ar ammunition, propel-

ling charges and primed cartridge cases for

semifixed and mor tar ammunition, grommets, and

Packaging and packing material authorized a t D

level is limited in quantiti es due to storage spac

requirements. The fluctuations of day-to-day de

mand on ammunition issues make it extremel

difficult to plan levels in advance so that actua

DS/GS MAINTENANCE PLANNING

4 1.

General

The proper performance of a maintenance operation

depe nds primarily upon planning. Before work on an y

item is begun, each operation

to

e

pe hr m ed must be

com pletely thought out. All of th e tools an d equipment

used t o do the job must be procured and d istributed to

th e poin ts where they wili

be

used. Complete rounds o r

items to be worked on must be inspected. Necessary

replac em ent parts or components must be determined,

th en procured, and stored. Supplies such a s paint, var-

nish, ste el wool, cardboard , and sealing compound mus t

be obtain ed.in the proper quantities. Men who are ex-

perienced in operation must be assigned to various sec-

tion s of th e job. Inexperienced men must receive tra in -

ing so th at they will

be

able to help when needed. Tech-

nical information must e obtained so tha t the job will

be

performed correctly. Consideration must

e

given

to

safety so th at each operation may be condu3ted w ith

the minimum possibility of injury toeither the operator

or t he equipment. Once the operations are under way,

provisions must

be

made for removing bottlenecks a nd

incre asing production, making operations more simple,

increasing safety, etc. The above examples are in-

tended

to

give an idea of the nature of the planning.

Th e sys tem used in planning jobs of other types by

deciding ahead of time-

What is

to

be done?

How th e work is

to

be done?

Who is

to

do the work?

Whe re is the work

to

be done?

applie s itself very well to maintenance ; an d the paper-

work

to

be discussed late r is merely a step in answ ering

these questions so

as to

build up to an official line

layout.

4 2. Job Planning Instructions

The reason for instructing

as

many men a s possible in

maintenance operations becomes obvious when the

mission of a n am munition unit is considered. The uni t

may be confronted in the field with a tremendous

am oun t of work. It may e necessary to draw on native

labor in order to per form

a number of jobs

simultaneously, Small details of men may have to be

sent

to

distan t locations to perform other work. Then

men in these details must utilize such labor and equip-

ment as will be available to them. The men in the

details then must rely upon their own knowledge

to

organize their line. They must do their own job plan-

ning a nd supervising.

4 3. Procedure

S and GS support units will perform ammuni-

tion maintenance and demilitarization of ammunition

only after receipt of a properly validated wor

authorization. Such work authorization will be the i

suance of a Maintenance Request DA Form 2407), a

indorsement to Amm unition Condition Report D

Form 2415), or a lette r of proposal. Instru ctions in t h

use of th ese form s are specified in TM 38-750.

b An assignm ent sheet work order) can be adde

where a validated work authorization does not furnis

sufficient information. I t may e made up by the main

tena nce officer. The assignment sh eet is a form of wor

A process flow sheet is a c har t for

recording, in a compact manner and in proper

se-

quence, the operations found in an o perating line. The

cha rt begins with the amm unition

to

be processed com-

ing from stora ge and follows it through each operation

to th e finished reworked item. Operations arrang ed in

proper sequence fall naturally into four major groups.

All types of ammunition to be processed must go

b. In p lanni ng th e flow sheets, the following ques-

tions should be considered:

2 ) Can a ny of th e operations

be

combined?

3)

Can any operations be done better in a

different order?

4 ) Can a ny of th e operations be simplified?work

simplification will

be

included in the basic plan to the

great est d egree possible and will be a continuing effort

when line is in operation.)

c.

secondary operation.

1)

A primary operation is one necessab to a

smooth flow of production. It also m ay be called a main

line operation.

2)

A

secondary operation is one necessary to the

completion of production, but not necessary to assure

an immediate smooth flow. Secondary operations may

be shu nted from the m ain line operations in to branch

lines to be returned a t a point farther along the main

line.

d.

Included in the flow sheet is a table listing the

number of each operation, the personnel required, the

tools to be used, and th e m aterials needed.

1) Materials

A careful study will be made of the

requirements for materials to go into the product.

Ma terials include such items

as

new com ponents, seal-

ing compound, paint,

etc.

2)

Equipment.

In selecting equipment, refer to

TM 43-9001-47 and TB 43-0195. The most appropriate

equipm ent available will be selected and used in the

operation. Improvised tools planned for use should be

approved by the appropriate commodity command.

3) PersonneL The num ber of workers assigned to

each operation will be kept a t a n efficient operational

minimum.

e.

The original flow sheet a cts

as

a blueprint for the

layout of th e line. It is useful as a reference and a s

guide for locating the various operating tables o

operating rooms. Using the flow sheet, a clear pictur

of th e job a s a whole can

be

obtained. C hanges probabl

wilvbe made in methods, tools, personnel, and sequenc

of operations after work has begun. All the change

will

e

incorporated into the final flow sheet, an

copies sent later to the next higher headquarters.

INSPECTION REQUIREMENTS

Section I. GENERAL

5 1. General

This chapt er outlines t he requirements for inspec-

tion of ammunition in DSIGS ammunition mainte-

nance organizations. These requirements are

contained in all ammunition maintenance manu-

als for specific classes of ammunition -34 TMs (e.g.,

TM 9-1300-251-34).

5 2. Purpose

Inspections in maintenance organizations are one

of the requirements of the Ammunition Surveil-

lance and Quality Evaluation Program (see AR

702-6, AR 740-1,AR 742-9, and SB 742-1). Ammuni-

tion surve illance includes the observation, inspec-

tion, and class ificat ion of ammunit ion and compo-

nents during movement, storage, and mainte-

surfaces, if not packaged) will be screened tho

oughly. DS/GS will perform pre-maintenanc

screening.

LOT NUMBERS

6-1. General

a.

This chapter describes the old and the new lot

numbering systems and the lot number markings used to

identify ammunition and explosive material.

6. The purpose of lot numbering of ammunition

outlined here is to provide the identification of material

necessary to assure accurate control of the movements

of items, to conserve and maintain surveillance records

and to provide a means of withdrawing from service

defective, deteriorated, hazardous, or obsolete ammuni-

tion and explosive material.

6-2. Description Use and Responsibility

of Lot Numbers

a.

Old System. The out-of-date system, which re-

mains in the field for all ammunition, the lot number

consists of a manufacturer's identification symbol,

followed by a dash and the serial number as illustrated:

(1)

Manufacturer s identification symbol.

The

manufacturer's identification symbol will consist of

one, two, or three letters assigned in a manner in-

dicating the identity of the arsenal, plant, depot, or sta-

tion, in case of loaded items, or indicating the contrac-

tor in case of components. For the Army, the Ammuni-

tion Procurement and Supply Agency will assign the

manufacturer's identification symbols to the manufac-

turer's of ammunition and ammunition components.

(2)

Znterfw number.

Each lot number, including

that of the first lot, will have

an

interfix number be-

tween the manufacturer's identification symbol and the

serial number. The interfix number indicates the lots

made according to a specific design or manufacturing

procedure.

(3) Serial number. The serial number will identify

the lot according to the sequence of production. A

number will tie assigned to each lot regardless of the

final disposition. The serial number will begin with 1

and continue in sequence until production of the item is

terminated or a change is made in the item or its produc-

tion which requires a different interfix number.

6 New System. For all ammunition end items and

their components including small arms, chemicals,

grenades, mines, pyrotechnics, etc., the ammunition lot

number consists of a manufacturer's identification sym-

bol, a numeric code showing the year of production, an

alpha code representing the month of production, a lot

interfix number followed by

a

hyphen, a lot sequenc

number and when necessary, an alpha character used a

an ammunition lot suffix to denote a reworked lot. Th

ammunition lot number does not exceed fourteen (14

characters in length and no characters are separated b

spaces. The minimum number of characters used i

thirteen (13). If one or two character manufacturer'

identification code is used, the remaining positions o

the three (3) character field are filled by dashes

-),

e.g

A- - AB-, etc. The following illustrates the con

struction of an ammunition lot number:

AMC 75

D

018 24 B

T i T i

(1) (2) (3) (4) (5) 6 )

(1) Manufacturer's identification symbol.

(2) A two (2) digit numeric code identifying th

year of production.

3)

A single alpha code signifying the month o

production.

(4) Lot interfix number.

(5) Lot sequence number.

(6) Ammunition lot suffix (the alpha suffix).

6-3. Description and Use of Lot Numbers for

Maintenance Operations

a. Old System.

For renovated, modified o

regrouped operations which are performed subseque

to acceptance of the munitions into the stockpile and t

restore them into issuable condition, the lotting will b

accomplished as listed below:

(1)

Ordinary maintenance.

Where new com

ponents replace like components (same model number

a lot suffix will be assigned by the responsible servic

,Example: US Army, Korea, Special Ammunition Depo

200 replaces fuzes on complete round Lo

LOP-l- the suffix furnished changes the lot numbe

to LOP-I-8A, B, C, etc., as applicable.

(2)

Extensive maintenance.

Where componen

replace different components, components are added o

where work is extensive enough to warrant mode

number change-(e.g., from Cartridge, 90-MM: HE

M71 to HE-T M71A1; from Fuze; M52 to M525; from

Fuze, MSOOAl to M520A1), new lots will be formed i

accordance with the requirements of the maintenanc

directive. Lot numbers will be assigned in the norma

manner except that the inte:fix number will start wit

500 instead of 1, and the manufacturer's symbol will b

that of the facility performing the work.

Example: US

Army Depot, Miesau, Germany, modifie

'sze, MT SQ , M5OOA1, Lot MA-2-23 which then

.-comes Fuze , MTS Q, M 520A1, Lot num ber

AHN-500-1 is assigned.

(3) Other maintenance (regrouping). Where

umerous lots are regrouped to form one lot, regardless

ormed in conjunc tion with regrouping or not, a new lot

umber will be assigned.

ups 81-M M Lo ts MA-2-24, MA-2-26, MA-2-28,

-600-1 is assigned.

4)

L ot suffixes. Lot suffixes are furnished the

facility, on request to the US Army Arm a-

AITN: DRSAR-

projects are canceled or indefinitely

suffix(es).

b.

New System. For renovated, modified or

into issuable condition, the lotting will be

lished as listed below:

(1) Ordinary maintenance. Where new com-

lace like compo nents (same model number),

e: US Army, K orea, Special Amm unition Depo t

replaces fuzes on complete round Lot LOP-

8-the suffix furnished changes the lot number to

B,

C, etc., as applicable.

(2) Extensive maintenance. Where compo nents

ce different com ponents, components are added o r

ange (e.g., from Cartridge, 90-MM: HE

be

formed in

instead of 1, an d the manufacturer's symbo l will be

e: US Army Depot, Miesau, Germany, modifies

SQ , MJOOA1, Lot MA-2-23 which then

81 A001 M001 is ass igned .

(3) Other maintenance (regrouping). Where

o form on e lot, regardless

number will be assigned.

Example: US Army, Fort Amador, Canal Zone

regroups 8 1MM Lots MA -2-24, MA-2-26, MA-2-28,

etc., Lot number CRV81AOOlG001 is assigned.

(4) Lo t suffixes. Lo t suffm es are furnished the

maintenance facility, on request to the

US

Army Arma-

ment Materiel Readiness Command, ATTN: DRSAR-

QAS, Rock Island, IL 61299. In those instances where

maintenance projects are canceled or indefinitely

delayed, the maintenance facility will request cancelia-

tion of the assigned suffix(es).

6-4.

Man ufacturer s Identification Symbol

a. Manu facturer's identification symbols ar e all

capital letters and d o not exceed three (3) alpha

characters. This symbol is a p a n of the ammunition lot

number. It is used to identify the arsenal, plant, depot,

station, private contractors, vendors, etc., which

manufactured, assembled, renovated, modified or load-

ed the specific lot of amm unitio n. It is used in the m ark-

ing of the ammunition and the ammunition

packings to

assure the accurate control of amm unition, ammunition

components and explosive materiel during movement,

storage, maintenance, issue, and receipt transactions.

b.

Manufacturer's identification symbols are

assigned to each manufacturer of ammunition, am-

munition components and explosive materiels. Dif-

ferent symbols for each plant are assigned to those

manufacturers who have m ore than one plant producing

ammunition items for the Government.

hmp1e:A erojet-General Corp., Azusa, California-

symbol AJA,

Aerojet-General Corp., Sacra men to, Cali-

fornia-symbol AJL,

Aerojet-General Corp ., Fullerton, Californ -

ia-symbol AJD,

Aerojet-General Corp ., Solid Rocket Plan t,

Sacr ame nto, California-symbol AJS.

Different symbols are assigned for individual plants

when the same manufacturing concern has two or m ore

different plants in the sam e city. These provisions apply

also to those manufacturers who operate GOCO

facilities in addition to p rodu cing am munition items for

the Government at privately owned facilities. It is the

responsibility of this organization to assure that no

manufacturer:^

identification symbols

be

duplicated.
