EXCESSIVE LUBRICATING OIL CONSUMPTION
Step 1.
Check that engine speed is correct for the specific gravity of liquid being pumped. Refer to pump
performance data plate.
Adjust SET POINT switch until engine is running at correct speed (para 2-6.g.).
Step 2.
Check that centrifugal pump unit is level.
Adjust jack extensions (leveling legs} with jack cranks so that unit is level.
Step 3.
Check exhaust. If exhaust discharge contains oil, excessive oil is being burned in engine cylinders
or around cylinder valve stems.
Notify organizational maintenance.
Step 4.
With engine not running, check oil cartridge, oil sump, drain tube fitting, drain tube, oil cooler, oil
pump cover, turbocharger feed line, and turbocharger return line for oil leaks.
If leaking, notify organizational maintenance.

LOW OIL PRESSURE
Step 1.
Check the oil pressure line hose for leaks. Leaks will cause false gage reading.
If leaking, notify organizational maintenance.
Step 2.
Check that crankcase is filled to the correct level.
CAUTION
Do not overfill. Oil will be blown out through crankcase breather if crankcase is overfilled.
a.
If level is low, remove oil filler cap and add proper grade oil as required to maintain correct oil level.
b.
Start engine and observe oil pressure gage. If oil pressure is still low, notify organizational maintenance.
