Marine Diesel Engines
-
Dismount, clean and remount the heat exchangers, preventing in this way to leave them exposed
to oxidizing substances. Check and if necessary replace the zinc anodes.
- Dismount and spray the sea water pump impeller with silicon grease spray or replace if
necessary.
- Connect the engine suction line to the fresh (no salt) water line. Take care to water flow;
the sea water pump flow at maximum engine speed is around 100 liters / min. Let the
engine run for about 15 min at 800 RPM to aid the circuit cleaning.
- Fill a proper tank with an opportune mixture of water and antifreeze fluid (depending on the
degree of protection that you would like to offer circuits) and connect the sea water suction pipe to
the tank. Start the engine at 800 RPM and wait for the mixture, sucked by the pump, to fill
completely the sea water circuit (until it comes out of the exhaust riser).
- Drain old oil from the oil sump and fill with clean oil for washing and start the engine (when
the engine is still hot, drain oil that is in the oil sump and repeat the operation, then it will be
possible to use this oil for other two or three times.) After the lubrication circuits washing
operation, drain again and fill the engine with new oil, properly added with the proper additives* till
the oil level is correct.
* INFO: for the oil treatment FNM® advises Bardahl2 Oil Treatment for long storage; while for washing and
storage it recommends Vanguard Storage 30 oil MIL-L-2104B (fill oil and let the engine run for 5 minutes at
800 RPM)
-
After filling with oil and any additive, start the engine and run for about 15 min at 800 RPM to
support lubrication of the engine internal mechanism.
-
Check for the coolant fluid. Drain the circuit and fill with the proper antifreeze coolant.
ATTENTION! Read the coolant producer instructions and the mixing table!
-
Check the fuel tank for dirt or deposits, if necessary clean it**.
**INFO: During the end of season or before the engine storage ,if possible, add an injector cleaning additive
to the fuel and take care to leave the tank empty after the treatment and cleaning. FNM advises Bardahl
injector cleaner.
- Dismount the fuel filter and clean it, if necessary replace it. Fill the fuel filter with a proper mixture
of fuel and additive for injector cleaning (leave empty if new).
- Fill a tank with a proper mixture of fuel and additive for injectors cleaning. Connect the fuel inlet
hose to the tank return line. Start the engine for some minutes at the minimum speed.
FNM advises Bardahl injector cleaner.
- To prevent cylinders rusting FNM® advises to spray or nebulize Vanguard® storage 30 protective
oil (MIL-L-2104; MIL-L-21260A) through the inlet manifold (dismounted air filter) and spin the
engine without starting it to facilitate oil suction (this operation can be carried out by spinning the
starter motor and consequently the engine with the fuel supply line disconnected to avoid the
starting and to facilitate only the movement/lubrication of the internal parts).
