CHAPTER 2. SERVICE
SECTION 1. MAINTENANCE
1. General
To make certain the generator set is always ready for operation, it must be inspected and maintained
regularly and systematically so that defects may be discovered and corrected before they result in serious
damage or failure of the equipment.
WARNING: ELECTRIC SHOCK, FLYING PARTS, OR FIRE CAN KILL OR IN-
JURE! STOP OPERATION IMMEDIATELY IF A SERIOUS OR POSSIBLY DAN-
GEROUS FAULT IS DISCOVERED.
2. Inspection
A periodic inspection should be established and maintained. A suggested inspection/check schedule is
provided in 2-2, Figure 1, however it may be modified as required to meet varying operating and environ-
mental conditions. If the generator set is mounted on a tow tractor, it is suggested that inspections be co-
ordinated.
3. Lubrication
A. General
Proper lubrication is one of the most important steps in good maintenance procedures. Proper lubrica-
tion means the use of correct lubricants and adherence to a proper time schedule. Frequency of lubri-
cation and recommended lubricants are indicated in Figure 1.
B. Generator
The 400-Hz generator requires NO lubrication. The rotor is supported by two ball bearing assemblies
which are lubricated and sealed at the factory for lifetime, maintenance-free operation. It is suggested
that generator bearings be checked after 5000 hours of operation.
C. Generator Controls
Generator controls and instruments require no scheduled periodic lubrication. A few drops of oil may
be required on door hinges occasionally to insure free an quiet operation.
D. Engine
Although the engine and its accessories require no more attention than any other similar installation,
they still inherently require a major portion of the generator set lubrication and maintenance. Recom-
mendations regarding engine lubrication have been taken from the engine manufacturer’s “Operator’s
Manual” and incorporated here to make them more readily available to operators and maintenance
personnel.
