APPENDIX II

MAINTENANCE ALLOCATION

Section I. INTRODUCTION

1. General

This appendix provides a summary of the main-

tenance operations for PP-l104C/G. It au-

thorizes categories of maintenance for specific

maintenance functions on repairable items and

components and the tools and equipment re-

quired to perform each function. This appendix

may be used as an aid in planning maintenance

operations.

2. Maintenance Function.

Maintenance functions will be limited to and

defined as follows:

a. Inspect. To determine the serviceability of

an item by comparing its physical, mechanical,

and/or electrical characteristics with estab-

lished standards through examination.

b. Test. To verify serviceability and to detect

incipient failure by measuring the mechanical

or electrical characteristics of an item and com-

paring those characteristics with prescribed

standards.

c. Service. Operations required periodically to

keep an item in proper operating condition, i.e.,

to clean (decontaminate), to preserve, to drain,

to paint, or to replenish fuel, lubricants, hydrau-

lic fluids, or compressed air supplies.

d. Adjust. To maintain, within prescribed limits,

by bringing into proper or exact position, or by

setting the operating characteristics to the

specified parameters.

e. Align. To adjust specified variable elements

of an item to bring about optimum or desired

performance.

f. Calibrate. To determine and cause correc-

tions to be made or to be adjusted on instru-

ments or test measuring and diagnostic

equipments used in precision measurement.

Consists of comparisons of two instruments, one

of which is a certified standard of known accu-

racy, to detect and adjust any discrepancy in the

accuracy of the instrument being compared.

g. Install. The act of emplacing, seating, or

fixing into position an item, part, module (com-

ponent or assembly) in a manner to allow the

proper functioning of the equipment or system.

h. Replace. The act of substituting a service-

able like type part, subassembly, or module

(component or assembly) for an unserviceable

counterpart.

i. Repair. The application of maintenance

services (inspect, test, service, adjust, align, cal-

ibrate, replace) or other maintenance actions

(welding, grinding, riveting, straightening, fac-

ing, remachining, or resurfacing) to restore

serviceability to an item by correcting specific

damage, fault, malfunction, or failure in a part,

subassembly, module (component or assembly),

end item, or system.

j. Overhaul.

That maintenance effort

(service/action) necessary to restore an item to a

completely serviceable/operational condition as

prescribed by maintenance standards (i.e.,

DMWR) in appropriate technical publications.

Overhaul is normally the highest degree of

maintenance performed by the Army. Overhaul

does not normally return an item to like new

condition.

k. Rebuild. Consists of those services/actions

necessary for the restoration of unserviceable

equipment to a like new condition in accordance

with original manufacturing standards. Re-

build is the highest degree of materiel mainte-

nance applied to Army equipment. The rebuild

operation includes the act of returning to zero

those age measurements (hours, miles, etc) con-

sidered in classifying Army equipments/

components.

3. Column Entries

a. Column 1, Group Number. Column 1 lists

group numbers, the purpose of which is to iden-

tify components, assemblies, subassemblies,

contains the noun names of components, as-

semblies, subassemblies, and modules for which

maintenance is authorized.

c. Column 3, Maintenance Functions. Column

3 lists the functions to be performed on the item

listed in column 2. When items are listed without

maintenance functions, it is solely for purpose of

having the group numbers in the MAC and

RPSTL coincide.

d. Column 4, Maintenance Category. Column 4

specifies, by the listing of a “worktime” figure in

the appropriate subcolumn (s), the lowest level

of maintenance authorized to perform the func-

tion listed in column 3. This figure represents

the active time required to perform that main-

tenance function at the indicated category of

maintenance. If the number or complexity of the

tasks within the listed maintenance function

vary at different maintenance categories, ap-

propriate “worktime” figures will be shown for

each category. The number of task-hours

specified by the “worktime” figure represents

the average time required to restore an item

(assembly, subassembly, component, module,

end item or system) to a serviceable condition

under typical field operating conditions. This

time includes preparation time, troubleshooting

time, and quality assurance/quality control time

in addition to the time required to perform the

Section Il. DEMOLITION OF

30. Authority for Demolition

The demolition procedures given in para-

graph 31 will be used to prevent the enemy

from using or salvaging this equipment. Demo-

lition of the equipment will be accomplished

only upon the order of the commander.

31. Methods of Destruction

The tactical situation and time available will

determine the method to be used when destruc-

tion of equipment is ordered. In most cases, it

is preferable to demolish completely some por-

tions of the equipment rather than partially

destroy all the equipment components.

a. Smash. Use sledges, axes, hammers, crow-

bars, and any other heavy tools available to

smash the cabinet, meters, and controls. Re-

move the top and side panels, and smash the

internal component.

TM 11-6130-246-12

MATERIEL TO PREVENT ENEMY USE

b. Cut. Use axes, handaxes, machetes and

similar tools to cut the wiring of the power

supply.

Warning: Be extremely careful with explo-

sives and incendiary devices. Use these items

only when the need is urgent.

c. Burn. Burn the technical manuals first.

Burn as much of the equipment as is flammable;

use gasoline, oil, flamethrowers, and similar

materials. Pour gasoline on the cut cables and

internal wiring and ignite it. Use a flame-

thrower to burn spare parts, or pour gasoline

on the spares and ignite them. Use incendiary

grenades to complete the destruction of the

unit.

d. Dispose. Bury or scatter destroyed parts

or throw them into nearby waterways. This is

particularly important if a number of parts

have not been completely destroyed.
