Section VI. PREPARATION FOR STORAGE OR SHIPMENT

2-41. Special Preservation and Packaging. Used engines which are to be stored indefinitely require extensive

corrosion preventive measures and careful packaging.

a. Corrosion Prevention.

(1)

Drain fuel and water systems completely.

(2)

Fill freshwater system with preservative by connecting a supply line to the drain connection for the system.

Cause system to overflow from expansion tank vent to ensure that all surfaces are coated. Drain

compound from the system and close the drain connection.

(3)

Drain the lubricating oil system. Remove oil filter elements, clean and wipe down interiors of filter

containers. Install new filter elements.

(4)

Break open a fitting in the lubricating oil piping system and connect the dscharge side of a separately-

driven pump to the disconnected engine lubricating oil system fitting.

(5)

Use a separately-driven pump to circulate preservative throughout the lubricating oil system of the engine

while the engine is being jacked or barred over. The discharge pressure of the separately-driven pump

should approximate the operating pressure of the engine lubricating oil system. Where possible, access

plates should be removed to determine that the compound reaches all points of the lubricating oil system.

(6)

The interior surfaces of the engine should be sprayed with preservative. This should include all internal

parts such as the crankcase, connecting rods, crankshaft, and lower cylinder bores.

(7)

Remove inspection and access covers and spray all gears, rockers, linkage, cams, and push rods with

preservative while the engine is being jacked or barred over with the turning gear. Spray all surfaces,

bearings linkages, and working parts of dry type clutches and reverse mechanism. (No harm will be done if

compound comes in contact with friction surfaces.)

(8)

Circulate MIL-L-21260, Type 1, Grade 10 or 30 through injectors, fuel lines, booster pump, and filters. Drain

all compound from the fuel system. (Do not use Grade 2 preservative in injection pumps or nozzles.)

(9)

Spray or brush preservative on internal surfaces of fuel tanks.
