APPENDIX B
MAINTENANCE ALLOCATION
Section I. INTRODUCTION
B-1. General
This appendix provides a summary of the maintenance
operations covered in the equipment literature. 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.
B-2. Maintenance Functions
Maintenance functions will be limited to and defined as
follows:
a Inspect. To determine serviceability of an item
by comparing its physical, mechanical, and electrical
characteristics with established standards.
b. Test. To verify serviceability and to detect incipient
electrical or mechanical failure by use of special
equipment such as gages, meters, etc. This is
accomplished with external test equipment and does not
include operation of the equipment and operator type
tests using internal meters or indicating devices.
c Service. To clean, to preserve, to charge, and to
add fuel, lubricants, cooling agents, and air. If it is
desired that elements, such as painting and lubricating,
be defined separately, they may be so listed.
d. Adjust. To rectify to the extent necessary to bring
into proper operating range.
e. Align. To adjust two or more components or
assemblies of an electrical or mechanical
system so that their functions are properly synchronized.
This does not include setting the frequency control knob
of radio receivers or transmitters to the desired
frequency.
f. Calibrate. To determine the corrections to be made
in the readings of instruments or test equipment used in
precise measurement. Consists of the comparison 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 with the
certified standard.
g. Install. To set up for use in an operational
environment such as an encampment, site, or vehicle.
h. Replace. To replace unserviceable items with
serviceable like item.
i. Repair. To restore an item to serviceable condition
through correction of a specific failure of unserviceable
condition. This function includes, but is not limited to
welding, grinding, riveting, straightening, and
replacement of parts other than the trial and error
replacement of running spare type items such as fuses,
lamps, or electron tubes.
j. Overhaul. Normally, the highest degree of
maintenance performed by the Army in order to minimize
time work in process is consistent with quality and
economy of operation. It consists of that maintenance
necessary to restore an item to completely serviceable
condition as prescribed by maintenance standards in
technical publications for each item of equipment.
Overhaul normally does not return an item to like new,
zero mileage, or zero hour condition.
