This section contains information for direct and gen-
eral support maintenance personnel to use in conjunction with and as
Operation of a deadlined generator set without a
preliminary examination can cause further damage to a disabled com-
ponent and possible injury to personnel.
By careful inspection and
such damage and injury can be avoided, and in addi-
tion the causes of faulty operation of a set or component can often
be determined without extensive disassembly.
Inspection and troubleshooting are performed either
while a disabled component is still mounted in the generator set or
after it has been removed.
Inspection made with the component mounted
in the set is for the most part visual and is performed before
attempting to operate the set.
The object of this inspection is to
determine the condition of the component and, if found defective, to
take precautions to prevent any further damage.
Inspection made after the component is
removed from the set verifies the diagnosis made when the component
was in the set, uncovers further defects, or determines malfunctions
if the component alone is received by the direct support maintenance
This inspection is particularly important in the last case
because it is often the only means of determining the malfunction
without completely disassembling
