(11) Rotate the engine crankshaft two or three revolutions every 3 weeks.

b. Long Term Storage. When the generator set is to be stored for 6 months or more, the following

procedures must be performed.

(1) The engine must be started and the speed gradually increased to 1200 RPM with no load. Operate

the engine until the water temperature reaches 160 (71 ). Stop the engine and drain the old oil.

(2) Fill the crankcase to the full mark on the dipstick with preservative oil, U.S. Military Specification

MIL-L-21260, Type P-10, Grade 2, SAE 30.

(3) Disconnect both fuel lines at the fuel supply tank. Fill two portable containers, one with diesel fuel

and the second with preservative oil U.S. Military Specification MIL-L-644, Type P-9.

(4) Start the engine with the fuel inlet line pulling fuel from the can with the diesel fuel. The injector

drain line can flow into the container with the diesel fuel. After the engine is started and is running at

idle, move the fuel inlet line to the container with the preservative oil. Stop the engine and

reconnect the fuel lines to the supply tank.

(5) The fuel tank must be drained and the drain plug installed. Make a cover for the filler vent with tape.

(6) Drain all the pumps, compressors, coolers, filters, and the crankcase. Replace all the plugs after

draining.

(7) Remove the intake and exhaust manifolds. Apply the preservative oil in a spray into the intake and

exhaust parts of the engine. Install the intake and exhaust manifolds.

(8) Inspect the coolant in the cooling system. If the coolant contains rust, drain and flush the system.

Then fill it with a rust preventing compound. Drain the system while it is hot and then replace the

plug. Use an oil that has rust inhibitors which will mix with the water. Flush the cooling system

before returning it to service.

(9) Make sure that all outside surfaces of the engine are painted. If painting is necessary, refer to step

c. of this procedure.

(10) Remove the valve covers and apply preservative oil to the rocker levers, valve stems, springs,

guides, crossheads and push rods. Install the covers.

(11) All engine openings must have a cover of heavy paper and tape.

(12) Put a tag on the engine to show the following:

(a) The engine has been prepared for storage.

(b) The coolant has been removed.
