PREPARING THE ENGINE FOR A LONG
PERIOD OF INACTIVITY
In order to prevent oxidation of the internal parts of the engine and
of certain components in the injection system, when the engine is
expected to be inoperative for periods of more than two months, the
following operations must be carried out in preparation for this:
1. Drain the lubricant from the sump, after first warming up the
engine.
2. Fill the engine with protective oil (complying with MIL-L-2160B
type 2 / ISO 3498/6743-4 HM standard), up to the "minimum"
level indicated on the dipstick. Start the engine and keep it running
for approximately 5 minutes.
3. Drain the fuel from the injection circuit, from the filter and from
the injection pump pipes.
4. Connect the fuel circuit to a tank containing CFB (ISO 4113)
protective fluid, and feed in the fluid by putting the circuit under
pressure and running the engine for approximately 2 minutes, after
first disabling the injection system. This operation can be
performed by polarising terminal 50 of the starter motor with a
positive voltage equivalent to the rated voltage of the system, using
a conductor provided for that purpose.
5. Nebulise approximately 67 g protective oil (10 g per litre
displacement) into the air inlet manifold, during the pressurised
filling operation described in the previous point.
6. Close all the suction, delivery, ventilation and bleeder openings in
the engine with suitable plugs, or seal them with adhesive tape.
7. Drain the residual protective oil from the sump. This oil can be
used again for a further 2 preparation operations.
8. Fit signs reading "ENGINE WITHOUT OIL" to the engine and to
the on-board control panel.
9. Drain the coolant, if it has not been mixed with suitable antifreeze
and corrosion inhibitors, and affix a sign to indicate the fact.
In the event of prolonged inactivity, the operations described must be
repeated every 6 months, following the procedure given below:
A) drain the protective oil from the sump;
B) repeat the operations described from point 2 to point 7.
Should you intend to protect external parts of the engine, proceed by
spraying anti oxidation (Anticorit) protective liquid on unpainted metal
parts, such as the flywheel, pulleys and the like, avoiding belts,
connector cables and electrical equipment. Protect the connectors
and electrical connections with VCI spray. Wrap the Engine in VCI bag
with hygroscopic salt bags.
