CHAPTER 16,7 MAINTENANCE SERVICES Marine equipment, vehicles, heavy equipment, and machine shop equip~ ment were maintained by the operating sections of the Service Operations Division. Extraordinary machine shop maintenance and maintenance of buildings, utilities, laundry and galley facilities, etc., were the responsibility of the Maintenance Section. Special groups within the sections were formed for refrigeration service, construction painting, maintenance painting, and office machine service. Periodic inspection of the hulls of marine craft was required. Operating crews kept constant check, and small repairs were made without beach- ing. Scaling, scraping, and painting were continuous operations, Mainte- nance crews made periodic inspections of all mechanical parts of vessels. Inspections included checking propellers for damage and proper pitch; checking shaft alignment, strut settings, and bearing alignment; checking engines, etc, Engines were taken out, overhauled, and repaired or replaced as necessary. Checks were also made of ramp hoists, anchor winches, pumps and other auxiliary equipment. Maintenance crews made weekly or bi-weekly inspections, depending upon the equipment concerned, on all trucks, light hauling equipment, and personnel carriers, including pick-ups, weapon carriers, jeeps, and motor scooters, As a result of these inspections, necessary repairs were made on vehicle bodies, mechanical equipment, and electrical equipment. Routine service such as lubrication and tire service was included as a matter of course on each inspection. Daily inspection and maintenance service was provided for all heavy construction equipment such as cranes, tractors, earth moving equipment, crushing plants, batch plants, road graders, road rollers, and ditchers. Repairs were made on this equipment whenever inspection indicated needs, Continuous inspection and service was also provided for all fixed heavy equipment such as lathes, drill presses, air compressors, and power tools. All buildings required continuous preventive maintenance. Shower stalls and fittings required removal, cleaning, painting, and replacement periodically; window shutters were oiled at intervals of not more than sixty days to prevent corrosion and freezing; doors, door hardware, toilets, and mirrors required periodic check and attention; building roofing required continual checking to take care of leaks developing at bolt holes, and periodic sealing was necessary at base lines to prevent seepage. CGontinual check was also necessary around the bases of concrete foundation slabs to guard against wind and rain erosion and resultant undercutting. This inspection was made atleast every two or three months and necessary corrective measures taken. Telephone instruments, electrical fixtures, plumbing and piping were under continual observation; and, as required, repairs were made. 16-33
