APPENDIX D
MAINTENANCE ALLOCATION
SECTION I. INTRODUCTION
D-1. General
This appendix provides a summary of the maintenance operations for Nonaircraft Nickel-Cadmium Batteries. It authorizes
categories of maintenance for specific maintenance functions on repairable items and components and the tools and equipment
required to perform each function. This appendix may be used as an aid in planning maintenance operations.
D-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 established standards through examination.
b.
Test. To verify serviceability and to detect incipient failure by measuring the mechanical or electrical characteristics
of an item and comparing 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, hydraulic fluids, or compressed air sup- plies.
d.
Adjust. To maintain, within prescribed limits, by brining 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 corrections to be made or to be adjusted on instruments 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 accuracy, 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 (component or assembly) in a
manner to allow the proper functioning of the equipment or system.
h.
Replace. The act of substituting a serviceable 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, calibrate, replace) or other
maintenance actions (welding, grinding, riveting, straightening, facing, 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 (. 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. Rebuild is the highest degree of materiel maintenance
applied to Army equipment. The rebuild operation includes the act of returning to zero those age measurements (hours,
miles, etc. ) considered in classifying Army equipments/components.
D-3. Column Entries
a.
Column 1, Group Number. Column 1 lists group numbers, the purpose of which is to identify components,
assemblies, subassemblies, and modules with the next higher assembly.
b.
Column 2, Component/Assembly. Column 2 contains the noun names of components, assemblies, sub-
assemblies, 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 species, by the listing of a "work time" figure in the appropriate
subcolumn(s), the lowest level of maintenance authorized to perform the function listed in column 3. This figure represents
the active time required to perform that maintenance 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, appropriate "work
time" figures will be shown for each category. The number of task- hours specified by the "work time" figure represents the
average time required to restore an item (assembly, sub- assembly, component, module, end item or system) to a
serviceable condition under typical field operating conditions. This time includes preparation time, troubleshoot- ing time,
and quality assurance/quality control time in addition to the time required to perform the specific tasks identified for the
maintenance functions authorized in the maintenance allocation chart. Subcolumns of column 4 are as follows:
C
Operator/Crew
O
Organizational
