ENGINE STORAGE
Engine Storage-(Short Term)
1 Month to 6 Months
This procedure describes the proper method for the
short term storage of an engine.
Prepare the Engine for Short Term Storage
1. Operate the engine at high idle until the coolant
temperature is 160° F (70° C).
2. Turn the engine off.
3. Disconnect the fuel lines to the engine fuel filter
and the injector return line.
4. Use a preservative oil. Use Dauber T Chemical
NoxRust No. 518, or equivalent. The oil must
meet Military Specification MIL-L-644, Type P-
9.
5. Fill two containers, one with diesel fuel, and the
second with preservative oil. Put both fuel lines
in the container of diesel fuel.
6. Start the engine.
7. After the engine is operating smoothly, transfer
the fuel supply line to the container of preserva-
tive oil. Operate the engine until the preserva-
tive oil flows out of the injector return line.
8. Turn the engine off. Connect the fuel lines to
the fuel filter and the injector return line.
9. Drain the oil pan sump, oil filters, and fuel filters.
10. Install the drain plugs in the oil sump. The sump
can remain empty until the engine is ready to be
returned to service.
Put a warning tag on the engine. The tag must
indicate:
• The engine does not contain oil.
• Do not operate the engine.

11. Disconnect the electrical wiring from the fuel
pump solenoid.
12. Turn the fuel pump manual shutoff valve coun-
terclockwise until it stops.
13. Crank the engine slowly. Spray lubricating oil
into the intake manifold and the inlet of the air
compressor.
14. Cover all of the openings with tape to prevent
dirt and moisture from entering the engine.
15. Drain the coolant.
NOTE: It is not necessary to drain the coolant if it is a
permanent type antifreeze with a rust inhibitor.
16. Store the engine in an area that is dry and has a
uniform temperature.
17. Bar turn the Crankshaft two or three revolutions
every 3 to 4 weeks.
Remove the Engine from Short Term Storage
1. Prime the lubricating system. Refer to Cummins
Engine Shop Manual, (Section 14-01, Engine
Run-in-Period).
2. Fill the coolant system if necessary.
3. Adjust the injector and the valve clearance.
Refer to Cummins Engine Shop Manual, (Sec-
tion 00-02, Engine Assembly).
4. Tighten the intake manifold mounting cap
screws to specified torques, refer to the Cum-
mins Service Manual for specifications.
5. Fill the oil pan sump, oil filters, and fuel filters
with recommended lubricants and fuels.
