CHAPTER 16 GENERATOR SET TESTS AFTER OVERHAUL REPAIR INSTRUCTIONS Section I. INSPECTION 16-1 General. a. A thorough inspection of the generator set shall be conducted to insure that workmanship and materials are satisfactory. b, The inspection shall be conducted each time the-generator set is overhauled or rebuilt. 16-2. Housing and Frame Inspection. a. Check-that lifting eyes are installed and firmly secured. b. Check that drain holes are open to prevent moisture accumulation. c. Insure that exposed parts are properly treated to resist corrosion. d. Open and close panel doors, engine area doors, and-generator area doors to insure proper installation and freedom of motion. e. Inspect movable door gasketing to insure that it is weatherproof. f. Check that all caps and covers are equipped with ties, chains, or other ties to prevent loss. Section II. 16-6. General. a. The tests described in this section require generator set operation and provide verification of generator set performance characteristics. NOTE All tests shall be conducted with the 240/416 volt connections, unless other- wise specified. All tests, that are ap- plicable, will be conducted on both Mode I and Mode II generator sets. Mode I tests shall be conducted at 60 Hz only unless otherwise specified. 16-3. Engine Inspection. a. Check mounting bolts of all components and accessories to insure that they are firmly secured. b.

OPERATING TESTS c. Temperatures will be measured by means of approximately located thermocouples and properly calibrated read-out devices. Thermocouples will be insulated from contact with other metals, as practi- cal. Temperatures will be recorded in degrees Fahrenheit or Centigrade, depending on the instru- ment scale, but will be converted to degrees Fahren- heit in all cases. Barometric pressures will be measured by a mercurial barometer which will be corrected for the temperature of the scale, the mer- cury, for vapor pressure and for the location of the barometer with regard to altitude and latitude. Am- eroid barometers will not be used. d. Operational procedures required in support of the individual tests specified herein shall be per- formed as in the Operator and Organizational Main- b. Unless otherwise specified, all test instrumen- tenance Manual. tation will be in accordance with Military Standardi- zation Handbook MI L-HDBK- 705 and Military Standard e.
