4.12 Product preservation
Important
• If the engines are not to be used for 6 months, they must
be protected by carrying out the operations described in
Engine storage (up to 6 months) (Par. 4.13).
• If the engine is still not in use after the first 6 months, it is
necessary to carry out a further operation to extend the
protection period (more than 6 months) (Par. 4.14).
• If the engine is not to be used for an extended period, the
protective treatment procedure must be repeated within 24
months of the previous one.
4.13 Engine storage up to 6 months
Before storing the engine check that:
• The environments are not humid or exposed to bad weather.
Cover the engine with a proper protective sheet against
dampness and atmospheric contaminants.
• The place is not near electric panel.
• Avoid storing the engine in direct contact with the ground.
4.14 Engine storage over 6 months
Follow the steps described in Par. 4.13.
1 - Engine oil replacement (Par. 5.1).
2 - Refuel with fuel additives for long storage.
The following additives are recommended:
DEFA Fluid Plus (Pakelo Lubricants),
Diesel Treatment (Green Star),
Top Diesel (Bardhal),
STP
®
Diesel Fuel Injector Treatment.
3 - With expansion tank:
make sure that the coolant is up to the maximum level.
4 - Without expansion tank:
Top liquid up until the pipes inside the radiator are covered
by about 5 mm.
Do not overll the radiator, but leave room for the fuel to
expand.
5 - Start the engine and keep it idle at minimum speed for 2
minutes.
6 - Bring the engine to 3/4 of the maximum speed for 5÷10
minutes.
7 - Turn off the engine.
8 - Completely empty the fuel tank.
9 - Spray SAE 10W-40 on the exhaust and intake manifolds.
10 - Seal the exhaust and intake ducts to prevent foreign
bodies from entering.
11 - When cleaning the engine, if using a pressure washer
or steam cleaning device, avoid directing the nozzle on
electrical components, cable connections and sealed
rings (oil seals etc).
If cleaning engine with a pressure washer or steam
cleaner, it is important to maintain a minimum distance of
at least 200mm between the surface to be washed and the
nozzle - avoiding absolutely electrical components such
as alternators, starter motors and engine control units
(ECU).
12 - Treat non-painted parts with protective products.
13 - Loosen the alternator belt Par. 4.9.
If the engine protection is performed according to the
suggestions indicated no corrosion damage should occur.
4.15 Engine starting after storage
1 - Remove the protective sheet.
2 - Use a cloth soaked in degreasing product to remove the
protective treatment from the external parts.
3 - Inject lubricating oil (no more than 2 cm
3
) into the intake
ducts.
4 - Adjust the alternator belt tension (Par. 4.9).
5 - Refill the tank with fresh fuel.
6 - Make sure that the oil and the coolant are up to the
maximum level.
7 - Start the engine and keep it idle at minimum speed for a
two about minutes.
8 - Bring the engine to 75% of maximum rated speed for 5 to
10 minutes.
9 - Stop the engine while the oil is still hot
(Par. 5.1), discharge the protective oil in a suitable
container.
Warning
• Over time, lubricants and filters lose their properties, so it is
important consider whether they need replacing, also based
on the criteria described in Tab. 4.2.
10 - Replace the filters (air, oil, fuel) with original spare parts.
11 - Pour new oil (Par. 3.5) up to the maximum level.
12 - Empty the cooling circuit completely and pour in the new
coolant up to the maximum level (Par. 3.6).
