To prevent oxidation to the internal parts of the engine and
to some components of the injection system, if idle periods
exceeding two months are expected, the engine needs to
be prepared
with six-months periodicity , proceeding as
follows:
1. Drain the lubricating oil from the sump, after heating the
engine.
2. Pour 30/M protective oil (alternatively, oil conforming
with MIL 2160B Type 2 specifications) into the engine to
the “minimum” level marked on the dipstick.
Start the engine and let it run for about 5 minutes.
3. Drain the fuel from the injection line and from the filter,
taking care to avoid letting the fuel come in contact with
the auxiliaries belt.
4. Connect the fuel line to a tank containing CFB protec-
tive liquid (ISO 4113) and assist the inflow of the liquid
by pressurizing the line and turning the engine over for
about 2 minutes, after excluding the operation of the
injection system.The required operation may be carried
out by directly polarizing the terminal 50 of the electric
starter motor with positive voltage 12 V, using a con-
ductor prepared for the occasion.
5. Nebulize 30/M protective oil at the rate of about 60 g
(10 g per liter of displacement) into the turbocharger
intake, while the engine is turning over as described
above.
6. Close with suitable stoppers or seal with adhesive tape
all engine intake, exhaust, aeration and venting ports.
7. Drain the residual 30/M protective oil from the sump;
it may be re-used for 2 more engine preparation
operations.
8. Apply tags with the inscription “ENGINE WITHOUT
OIL” on the engine and onboard panel.
9. Drain the coolant, if it has not been mixed with
antifreeze and corrosion inhibiting agents, affixing tags to
indicate that the operation has been carried out.
If external parts of the engine are to be protected, spray pro-
tective liquid OVER 19 AR onto unpainted metal parts, such
as flywheel, pulleys and others; avoid spraying belts, connec-
tor cables and electrical equipment.
1. Drain the residual protective oil type 30/M from the
sump.
2. Pour lubricating oil into the engine, as provided by the
specifications and in the quantities set out in the Table of
Refills.
3. Drain the CFB protective liquid from the fuel line, com-
pleting the operations set out in item 3 of “. PREPARING
THE ENGINE FOR LONG IDLE PERIODS”.
4. Remove the caps and/or the seals from the engine’s
intake, exhaust, aeration and vent ports, restoring nor-
mal operating conditions. Connect the turbocharger
intake to the air filter.
5. Attach the fuel lines to the vessel’s fuel tank, completing
the operations set out in item 4 of “. PREPARING THE
ENGINE FOR LONG IDLE PERIODS”.
During the filling operations, attach the fuel tank return
pipe to a collecting container to prevent residues of CFB
protective liquid from flowing into the vessel’s fuel tank.
6. Verifiy the quantity of cooling liquid and refill as provid-
ed by the specifications.
7. Start the engine and keep it running until idling speed
has completely stabilized.
8. Shut the engine down and delete the “errors” which
may have been stored in the injection system ECU dur-
ing the operation stabilization phases. For reset opera-
tion, see “Blink code” paragraph in Section 4.
9. Remove the tags with the inscription “ENGINE WITH-
OUT OIL” from the engine and from the panel.
