The Scavenge Screen Has An Obstruction
Remove the screens that are in the inlet passage of the scavenge pump.Each inlet to the scavenge section of the pump contains a screen.
Check the screens for obstructions. Check the filter element for foreign material. Use a magnet in order to separate ferrous particles from nonferrous particles.
Replace the screens.
Start the engine.
Stop the engine.
Obtain an oil sample.

The original problem is resolved. The air has been removed from the oil system.Results
OKAY: Stop.
NOT OKAY: The cause of the problem is uncertain. Call technical support with the information that has been gathered.Power Train Oil Temperature Is High Probable Causes
Power train oil level is low
The power train oil cooler has leaks
The power train oil contains a large amount of air
The temperature gauge is not operating properly.
The power train oil cooler is plugged.
The fan motor is not operating properly
The scavenge screen is obstructed. There is a large amount of oil.
Personal injury or death can result from escaping fluid under pressure.Escaping fluid under pressure, even a very small pin-hole size leak, can penetrate body tissue and cause serious injury and possible death. If fluid is injected into your skin, it must be treated immediately by a doctor familiar with this type of injury.Always use a board or cardboard when checking for a leak.

Code and Description    Conditions which Generate this Code    System Response    
E030 (2)
Power Train Oil Tank Temperature High     Activated when the oil temperature reaches
120° C (248° F) for 5 seconds.     Warning level 2 alerts the operator that a machine system requires attention. The operator should check the involved system condition or perform maintenance on the involved system at the earliest possible time. On the electric drive tractors, all Level 2 Events are logged.    Recommended Actions
Note: Care must be taken in order to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting, and repair of the machine. You must be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component that contains fluid. Dispose of all fluids according to local regulations.Power Train Oil Level Is Low
Ensure that the power train oil level is in between "OPERATING ZONE" marks on the dipstick.
ReferenceRefer to (D8T) Operation and Maintenance Manual, SEBU9087, "Power Train Oil Level - Check"ReferenceRefer to (D9T) Operation and Maintenance Manual, SEBU8736, "Power Train Oil Level - Check"If the oil level is low proceed, to "The Power Train Oil Cooler has Leaks" in order to determine if the power train oil is leaking.The Power Train Oil Cooler has Leaks
Inspect the oil and coolant reservoirs on the machine and perform an SOS analysis to determine if there is cross contamination between the systems.Thoroughly examine all surfaces, tubes, and connections on the power train oil cooler for signs of leaks. If oil is leaking, dirt and dust
