Turbocharger
—Since turbocharg-
er bearings are pressure lubricat-
ed through the external oil line
leading from the oil filter adapter
while the engine is operating, no
further attention is required.
However, the turbocharger air inlet
and turbine outlet connections
should be sealed off with moisture-
resistant tape.
13. Apply a non-friction rust preventive
compound to all exposed engine
parts. If convenient, apply the rust
preventive compound to the
engine flywheel. If not, disengage
the clutch mechanism to prevent
the clutch disc from sticking to the
flywheel.
NOTE:
Do not apply oil, grease or any
wax base compound to the flywheel.
The cast iron will absorb these sub-
stances, which can “sweat” out during
operation and cause the clutch to slip.
14. Drain the engine cooling system.
15. Drain the preservative oil from the
engine crankcase. Reinstall and
tighten the drain plug.
16. Remove and clean the battery and
battery cables with a baking soda-
water solution and rinse with fresh
water. Do not allow the soda solu-
tion to enter the battery. Add dis-
tilled water to the electrolyte (if
necessary) and fully charge the
battery. Store the battery in a cool
(never below 0°C or 32°F) dry
place. Keep the battery fully
charged and check the level and
specific gravity of the electrolyte
regularly.
17. Insert heavy paper strips between
the pulleys and drive belts to pre-
vent sticking.
18. Seal all engine openings including
the exhaust outlet, with moisture-
resistant tape. Use cardboard, ply-
wood or metal covers where
practical.
19. Clean and dry the exterior painted
surfaces of the engine and spray
with a suitable liquid automobile
body wax, a synthetic resin var-
nish, or a rust preventive com-
pound.
20. Protect the engine with a good
weather-resistant tarpaulin and
store it under cover, preferably in a
dry building which can be heated
during the winter months.

NOTICE:
Failure to properly seal off turbo-
charger air inlet and exhaust outlet
openings before engine storage may
permit air drafts to circulate through
the turbocharger and rotate the tur-
bine/compressor shaft without an
adequate flow of lubricating oil to the
center housing bearings. This can
result in severe bearing damage.
Extended Storage
(More than 30 Days)
To prepare an engine for extended
storage (more than 30 days), follow
this procedure:
1. Drain the cooling system and flush
with clean, soft water. Refill with
clean, soft water and add a rust
inhibitor to the cooling system.
2. Circulate the coolant by operating
the engine until normal operating
temperature is reached.
3. Stop the engine.
4. Drain the engine crankcase, then
reinstall and tighten the 3/4"-14
square, magnetic oil drain plug to
45-50 N•m (33-37 lb-ft) torque.
Install new lubricating oil filters.
5. Fill the crankcase to the proper level
with a 30-weight preservative lubri-
cating oil MIL-L-21260C, Grade 2.
6. Drain the fuel tank. Refill with
enough clean No. 1 diesel fuel or
pure kerosene to permit the engine
to operate for about ten minutes. If
draining the fuel tank is not conve-
nient, use a separate, portable sup-
ply of recommended fuel.
NOTE:
If engines in vehicles are
stored where condensation of water in
the fuel tank may be a problem, add
pure, waterless isopropyl alcohol (iso-
propanol) to the fuel at a ratio of one
pint to 125 gallons of fuel, or 0.10% by
volume. Where biological contamina-
tion of fuel may be a problem, add a
biocide such as Biobor JF (or equiva-
lent) to the fuel. When using a biocide,
follow the manufacturer's concentra-
tion recommendations, and observe
all cautions and warnings.
7. Drain the fuel system and remove
the fuel filters. Dispose of used fil-
ters in an environmentally respon-
sible manner, according to state
and/or federal (EPA) recommen-
dations. Fill new filters with No. 1
diesel fuel or pure kerosene, and
reinstall on the engine.
8. Operate the engine for five minutes
to circulate the clean fuel oil
throughout the engine. Be sure the
engine fuel system is full.
Disconnect the fuel return line and
the inlet line at the primary filter
and securely plug both to retain
the fuel in the engine.
9. Service the air cleaner.
10.
Transmission
—Follow the manu-
facturer's recommendations for
prolonged storage.
11.
Power Take-Off
— (If equipped)—
Follow the manufacturer's recom-
mendations for prolonged storage.
