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, 8-1
