2.2
Causes
D
The servo oil pump has damage.
D
The safety device on the pump drive has sheared (see
Unit).
D
The actuators CV7221C, CV7222C and CV7223C are defective.
D

2.3
Procedures
If one servo oil pump becomes defective, the engine can operate through the full load
range.
CAUTION
Damage Hazard: Do not operate the engine with one
unserviceable servo oil pump for a long period. If the other servo
oil pump becomes defective, damage can occur and the engine
cannot operate.
1) Replace the defective servo oil pump as soon as possible (see
release and drain and the Maintenance Manual 5551

opening).
D
The fuel injection is cut out automatically (Inj. CUT OFF) on the related cylinder,
and a slow down signal will be released.
D
The level switch LS3444A activates an alarm indication because of leakages at
the hydraulic pipes to the exhaust valves (see
Servo oil leakage
system).
