CHAPTER 8
MAINTENANCE/COSAL
Throughout this chapter, you will be referred to
other publications for additional information on the
topic being discussed. To receive the best training
possible and to improve your knowledge, you must read
the publications and become familiar with the
information they contain.
Electronics Installation and Maintenance Book
(EIMB), General Maintenance, NAVSEA SE000-
00-EIM-160, is an excellent handbook to use to review
maintenance organization and to increase your
knowledge of electronics maintenance. You should also
refer your junior technicians to this manual. As a training
aid, it will benefit both you and your command.
Shipboard electronics maintenance consists of the
following duties:
1.
2.
3.
4.
5.
Performing operational tests to establish
readiness.
Performing power tests, calibration,
nonoperational adjustments, and other prescribed
qualitative and quantitative performance
measurements to establish functional evaluations
on systems and equipments.
Restoring or replacing deteriorated or defective
parts, and replenishing lubricants, coolants,
falters, and other consumable items.
Correcting failures and damage during
operations.
Protecting insulation, insulators, and conductors
by removing rust, lint, and conductive and
nonconductive deposits of fluid, and protecting
equipment from the accumulation of these
substances and from man-made hazards.
In short, shipboard electronic maintenance consists
of preventative and corrective maintenance on all
electronic systems, subsystems, equipments, and test
equipment.
Because of the complexity of the electronic
equipment and systems we now have on our ships, it is
most important that electronics personnel be properly
trained, supervised, and available for maintenance of
these equipments and systems at any given time. This
means that as the LPO or LCPO, you must assign your
people wisely, train them well, and establish effective
schedules for routine checks and tests. You also need
to ensure that all of your allowed parts, test
equipment, and tools are maintained, and that all
pertinent forms and publications are available. In this
chapter we will discuss the various aspects of
supervisory maintenance.
LEVELS OF EQUIPMENT
MAINTENANCE
There are three levels of maintenance performed by
the Navy: organizational, intermediate, and depot.
ORGANIZATIONAL
MAINTENANCE
Organizational maintenance is performed by and is
the responsibility of, you guessed it, you and your
technicians, and is performed on your assigned
equipment. The phases of organizational maintenance
are normally inspecting, servicing, lubricating,
adjusting, and the replacing of parts, minor assemblies,
and subassemblies.
INTERMEDIATE
MAINTENANCE
Intermediate maintenance is the responsibility of
and is performed by designated maintenance activities
for direct support of using organizations. The phases of
intermediate maintenance are (1) the calibration, repair
or replacement of damaged or unserviceable parts,
components, or assemblies; (2) the emergency
manufacture of nonavailable parts; and(3) the providing
of technical assistance to using organizations. This
includes maintenance performed by aircraft carriers,
tenders in support of other ships’ public works
departments, and officially designated shore activities.
DEPOT LEVEL
MAINTENANCE
Depot maintenance is performed on material
requiring major overhaul or a complete rebuilding of
parts, assemblies, subassemblies, and end items,
including the manufacture of parts, modifications,
