APPENDIX E
MAINTENANCE ALLOCATION
Section I. INTRODUCTION
E-1. General
This appendix provides a summary of the maintenance
operations for the Pulse Generator AN/USM-359A. 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.
E-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 conditions, i.e., to
clean (decontaminate), to preserve, to drain, to paint, or
to replenish fuel, lubricants, hydraulic 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
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 (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. Rebuild is the highest
degree of material 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.
