This evaporation and condensing process offers full
protection to surfaces that cannot be reached with
preservatives that require a direct application. This
process is also easier to clean from the engine when
removing the engine from storage.
The volatile vapors are removed by simply running
the engine to operating temperature. A mineral oil
base is left behind after the volatile vapors are
removed. The oil should then be drained and new oil
and filters installed.
Note: Engines that are stored for more than 6
months must be prelubed and rotated in 6-month
intervals.
If an engine is not used, oil can run off the following
parts that normally receive lubrication: cylinder walls,
piston rings, main bearings, connecting rod bearings,
crankshaft, and gears.
This lack of lubricant allows corrosion to begin to
appear on the metal, especially in areas of high
humidity (water content in the air).
When the engine is started again, before these
surfaces receive oil, the metal-to-metal contact will
cause wear. To minimize this wear, use the starter to
turn the engine with the throttle in the FUEL OFF
position. When oil pressure is shown on the pressure
gauge, start the engine.
Preparing the Engine for Storage
1. Clean the engine of any dirt, rust, grease, and oil.
Inspect the exterior. Paint areas that contain paint
damage with a good quality paint.
2. Remove any dirt from the air cleaner or cleaners.
Check all seals, gaskets, and the filter element for
damage.
3. Apply lubricant to all points shown in the Operation
& Maintenance Manual, "Lubrication &
Maintenance Table" for your equipment.
4. Drain and replace the crankcase oil and change
the oil filter or filters. For the proper procedure,
refer to the Operation & Maintenance Manual for
your equipment.
5. If equipped with an air starter, fill the reservoir with
a mixture of 50 percent VCI oil and 50 percent
engine oil.
6. Add VCI oil to the crankcase at the rate of 3 to 4
percent by the volume of the crankcase.
Note: If the engine crankcase is full, drain enough
engine oil so the mixture can be added.
Engine Storage Procedure - Check
7. Remove the air filter element or elements. Turn the
engine at cranking speed with the throttle control
in FUEL OFF position. Use a sprayer to add a
mixture of 50 percent VCI oil and 50 percent
engine oil into the air inlet or turbocharger inlet.
Note: VCI oil mixture is also to be added to the inlet
by removing a plug for checking boost pressure/
temperature at the cylinder head air inlet area. The
sprayer should produce a fog to ensure it is drawn
into each cylinder. The minimum application rate is
5.5 mL per L (3 oz per 1000 cu in) of engine
displacement.
8. Use a sprayer to apply a 50 percent VCI oil and 50
percent engine oil mixture into the exhaust
openings. The minimum application rate is
5.5 mL per L (3 oz per 1000 cu in) of engine
displacement. Seal the exhaust pipe, including
any drain holes in the muffler.
9. Remove the fuel from the secondary fuel filter
housing or empty and reinstall the spin-on fuel
filter element to remove any dirt and water.
Clean the primary fuel filter. Fill with calibration
fluid or kerosene. Install the primary fuel filter and
operate the priming pump. This procedure will
send clean fuel to the secondary filter and engine.
10. Open the fuel tank drain valve and allow any
water or dirt to drain from inside the fuel tank.
Apply a spray of 30 mL per 30 L
(1 oz per 7.50 gal U.S.) of fuel tank capacity to
prevent rust in the fuel tank. Add 0.15 mL per L
(.02 oz per 1 gal U.S.) of commercial biocide such
as Biobor JF or and equivalent to the fuel.
Apply a small amount of oil to the threads on the
fuel tank filler neck and install the cap. Seal all
openings to the tank to prevent evaporation of the
fuel and preservative.
11. Spray the VCI oil mixture (50 percent VCI oil and
50 percent engine oil) on the flywheel, ring gear
teeth, and starter pinion. Install the covers to keep
in the VCI vapors.
12. Apply a heavy amount of multipurpose grease
(MPGM) to all outside parts that move, such as
rod threads, ball joints, linkage, and other
components.
Note: Install all covers and ensure that the tape has
been installed over all the following openings: air
inlet, exhaust openings, flywheel housing, crankcase
breather, aftercooler condensate drains, and dipstick
tubes.
