MACHINE STORAGE
The engine should be stored in a building which
is dry and can be heated during the winter
months. Moisture absorbing chemicals are avail-
able commercially for use when excessive damp-
ness prevails in the storage area.
TEMPORARY STORAGE (30 DAYS OR LESS)
To protect an engine for a temporary period of
time proceed as follows:
1. Drain the engine crankcase.
2. Fill the crankcase to the proper level with the
recommended viscosity and grade of oil.
3. Fill the fuel tank with the recommended grade
of fuel oil. Operate the engine for two minutes at
1200 rpm and no load.
NOTE: Do not drain the fuel system or the crank-
case after this run.
4. Check the air cleaner and service it, if neces-
sary as outlined under Air System.
5. If freezing weather is expected furing the stor-
age period, add a high boiling point type anti-
freeze solution in accordance with the
manufacturer’s recommendations. Drain the
raw water system and leave the drain cocks open.
6. Clean the entire exterior of the engine (except
the electrical system) with fuel oil and dry it with
air.
7. Seal all of the engine openings. The material
used for this purpose must be waterproof, vapor-
proof and possess sufficient physical stength to
resist puncture and damage fro m the expansion
of entrapped air.
An engine prepared in this manner can be re-
turned to service in a short time by removing the
seals at the engine openings, checking the engine
coolant, fuel oil, lubricating oil, transmission,
and priming the raw water pump, if used.
EXTENDED STORAGE (30 DAYS OR MORE)
When An Engine Is To Be Removed From Opera-
tion For An Extended Period Of Time,prepare It
as follows:
1. Drain and thoroughly flush the cooling sys-
temwith clean, soft water
2. Refill the cooling system with clean, soft water.
3. Add a rust inhibitor to the cooling system (re
fer to page 4-7, “Corrsion Inhibitor).
4. Remove, check and reconditon the injectors, if
necessary, to make sure they will be readyt to op-
erate when the engine is restored to service.
5. Reinstall the injectors in the engine, time
them, and adjust the valve clearance.
6. Circulate the coolant through the entire sys-
tem by operating the engine until normal operat-
ing temperature is reached (160°F. to 185°F).
7. Stop the engine.
8. Remove the drain plug and completely drain
the engine crankcase. Reinstall and tighten the
drain plug. Install new lubricating oil filter ele-
ments and gaskets.
9. Fill the crankcase to the proper level with a
30-weight preservative lubricating oil MIL-L-
21260, Grade 2 (P10), or equivalent.
10. Drain the engine fuel tank.
11. Refill the fuel tank with enough rust preven-
tive fuel oil such as Americal Oil Diesel Run-In
Fuel (LH 4089), Mobil 4Y17, or equivalent, to en-
able the engine to operate 10 minutes.
12. Drain the fuel filter and strainer. Remove the
retaining bolts, shells and elements. Discard the
used elements and gaskets. Wash the shells in
clean fuel oil and insert new elements. Fill the
cavity between the element and shell about two-
thirds full of the same rust preventive compound
as used in the fuel tank and reinstall the shell.
