ISM, ISMe, and QSM11 – 000-006   Engine Storage – Short Term

This procedure describes the proper method to prepare an engine for short term storage (one to six months).

Operate the engine at High Idle speed until he coolant temperature indicator reaches 70°C [160°F].

Shut off the engine.

Remove the fuel lines to the engine fuel filter and the injector return line.

Use Daubert Chemical NoxRust Number 518 Preservative Oil or equivalent. The oil must meet Military Specification 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.

NOTE: The oil pan can remain empty until the engine is ready to use.

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.

WARNING  Do not pull or pry on the fan to manually rotate the engine. To do so can damage the fan blades. Damaged fan blades can cause premature fan failures which can result in serious personal injury or property damage.

Use the accessory drive shaft to rotate the crankshaft two to three revolutions every three to four weeks.

Remove the tape from the openings. Remove the warning tag.

Replace the oil, water, and fuel filters.

Prime the lubricating oil system.

Use clean diesel fuel to flush the preservative oil from the fuel system.

Fill the cooling system (if necessary)

Adjust the injector and valve clearance. Refer to Procedure 003-004 in Section 3.

Adjust the belt tension. Refer to Procedure 013-021 in Section 13.
