ENGINE STORAGE
ENGINE STORAGE
- When the engines are not for more than 6 months, they have to be protected performing the operations described in
the following pages.
- If the engine is not to be used for extensive periods, check the storage area conditions and the type of packaging and
make sure that these are suitable for correct storage.
If necessary, cover the engine with a proper protective sheet.
- Avoid storing the engine in direct contact with the ground, in environments that are humid and exposed to bad weather,
near high voltage electric lines, etc.
Important
If, after the rst 6 months, the engine is still not used, it is necessary to carry out a further measure to extend the pro-
tection period (see “Protective treatment”).
1 - Pour in the engine housing AGIP RUSTIA C protective
oil up to the maximum level.
2 - Fill up with fuel containing 10% AGIP RUSTIA NT.
3 - Make sure that the coolant is up to the maximum level.
4 - Start the engine and keep it idle at minimum speed for
some minutes.
5 - Bring the engine to ¾ of the maximum speed for 5÷10
minutes.
6 - Turn off the engine.
7 - Empty out completely the fuel tank.
8 - Spray SAE 10W on the exhaust and intake manifolds.
9 - Seal the exhaust and intake ducts to prevent foreign
bodies from entering.
10 - Thoroughly clean all external parts of the engine using
suitable products.
11 - Treat non-painted parts with protective products (AGIP
RUSTIA NT).
12 - Loosen the alternator/fan belt.
13 - Cover the engine with a proper protective sheet.
Caution - Warning
In countries in which AGIP products are not available, nd
an equivalent product (with specications: MIL-L-21260C).
Important
Maximum every 24 months of inactivity, the engine must be
started up by repeating all “Engine Storage” operations.
After the storage period and before starting up the engine and
preparing it for operation, you need to perform certain opera-
tionstoensuremaximalefciencyconditions.
1 - Remove the protective sheet.
2 - Remove any sealing devices from the exhaust and inta-
ke ducts.
3 - Use a cloth soaked in degreasing product to remove the
protective treatment from the external parts.
5 - Inject lubricating oil (no more than 2 cm3) into the intake
ducts.
6 - Adjust the alternator/fan belt tension.
7 - Turn the engine manually to check the correct movement
and smoothness of the mechanical parts.
8 - Rellthetankwithfreshfuel.
9 - Make sure that the oil and the coolant are up to the ma-
ximum level.
10 - Start the engine and after some minutes bring it to ¾ of
the maximum speed for 5-10 minutes.
11 - Turn off the engine.
12 - Remove the oil drain plug (see “Oil replacement”) and
discharge the AGIP RUSTIA NT protective oil while the
engine is hot.
13 - Pour new oil (see “Table of lubricants”) up to the maxi-
mum level.
14 - Replacethelters(air,oil,fuel)withoriginalspareparts.
15 - Empty the cooling circuit completely and pour in the new
coolant up to the maximum level.
Caution - Warning
Over time, a number of engine components and lubricants
lose their properties, so it is important considering whether
they need replacing, also based on age (see Replacement
table).
Important
Maximum every 24 months of inactivity, the engine must be
started up by repeating all “Engine Storage” operations.
