NOTE: This procedure describes the proper method to prepare an engine for short term storage (1 to 6 months).
Operate the engine at ‘‘High Idle’’ speed until the coolant temperature indicator reaches:
Temperature: 70°C [160°F]
Shut off the engine.
Remove the fuel lines to the engine fuel filter and the injector return line.
NOTE: Use Daubert Chemical NoxRust No. 518 Preservative Oil, or equivalent. The oil must meet Military Specifi-
cation MIL-L-644 Type P-9.
Fill two containers, one with diesel fuel, the second with preservative oil. Install both fuel lines in the container of
diesel fuel.
Start the engine.
After the engine is operating smoothly, transfer the fuel supply line to the container of preservative oil. Operate
the engine until the preservative oil is coming out of the injector return line.
Shut off the engine.
Install the fuel lines to the fuel filter and the injector return line fitting.
Drain the lubricating oil pan, the oil filters, and the fuel filter.
Install the drain plug in the oil pan.
Torque Value: 136 N•m [100 ft-lb]
NOTE: Place appropriate brightly colored tag on the engine, stating that the engine oil has been drained.
Turn the fuel pump manual shutoff valve counterclockwise until it stops.
Remove the electrical wiring from the fuel pump solenoid.
Drain the cooling system.
NOTE: It is not necessary to drain the coolant if it is a permanent type antifreeze with a rust inhibitor. Do not drain
the coolant if the engine is installed in a vehicle.
Cover all openings with tape to prevent dirt and moisture from entering the engine.
Install a warning tag on the engine. The tag must indicate that the engine does not contain oil and must not be operated.
Store the engine in an area that is dry and has a constant temperature.
Use the accessory drive shaft to rotate the crankshaft two to three revolutions every 3 to 4 weeks.
