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. Check designation and data plates for legibility.
c. Insure that fuel and hydraulic oil lines are
protected from damage due to vibration.
16-4. Generator Inspection.
a. Insure that generator leads are properly iden-
tified and protected from damage due to vibration.
b. Insure that inspection openings are protected
by screening or protective plates.
c. Check that the engine generator screws are
firmly secured.
See table 1-3 for proper torque
values.
16-5. Electrical Accessories Inspection.
a. Check all cable and harness assemblies for
secure fastenings and protection against chafing
and vibration.
b. Insure that all cable and harness connectors
are-firmly secured in their proper place.
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. All test results, for generator set overhaul,
MIL-STD-705A.
shall be logged on the appropriate forms as required.
