Raw Water Systems
Completely drain the raw water system by removing all the drain plugs from the raw water
pump, water shield manifolds, heat exchanger bonnets, and aftercooler. After the system has
been drained, inspect all zinc plugs (normally painted red) for corrosion damage.
Note!
To ensure complete drainage and evaporation during storage, DO NOT install the drain
plugs and zinc plugs. Place all removed plugs in a cloth bag and fasten the bag to the
engine for storage.
Caution!
When finished all above operations of lubricating oil system and coolant system, then
start the engine for 5 minutes at low idle rated speed.
Turn off the engine and wait about 30 minutes to get it cooled completely, then make
operations as follows.
Fuel system
Fuel nozzle or spark plug
Remove the fuel nozzles or spark plugs and apply 30 ml (1 oz) of VCl oil mixture (50 percent
VCI oil and 50 percent engine oil) in each cylinder.
Use a bar or turning tool to rotate the engine slowly to put the oil on the cylinder walls. Install all
the fuel nozzles or spark plugs and tighten to the correct torque.
Intake and exhaust system
Air filter
Remove the air filter elements. Seal the air filter inlets, with VCI plastic bag and adhesive tape.
Use the starter to drive the engine, but no fuel. Then use a sprayer to add VCI oil dilution into
the air inlet and turbocharger inlet, multiple times, total 60s.
Exhaust openings
Use a sprayer to apply VCI oil dilution 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.
Vents
All vents i.e. engine inlet pipe, exhaust pipe, air cleaner inlet, coolant inlet & outlet, crankcase
breather, the crankcase breather and all other openings etc. must be carefully sealed with VCI
plastic bag and adhesive tape.
Note!
VCl oil mixture can also be added to the inlet by removing the plug for checking
turbocharger boost pressure. The minimum application rate is 5.5 ml per L (3 oz per
1000 cu in) of engine displacement.
