Section II TROUBLESHOOTING
4-5. INTRODUCTION.
Procedures for troubleshooting the engine and engine systems are given in table 4-1. These proce-
dures are limited to isolation of faulty components that can be repaired or replaced at the Organiza-
tional Maintenance level. (For repair and replacement, see section III in this chapter.) A complaint
by the operator may have a variety of causes, singly or in combination. For example, in cases where
internal engine parts have failed, the true cause can usually be found in one or more of the fluid
systems and less frequently in the internal parts themselves.
Therefore, a thorough repair would
include the investigation and discovery of the faulty system.
