5.7 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. 5.10).
• 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. 5.11).
• 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.
5.8 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.
5.9 Engine storage (over 6 months)
Follow the steps described in Par. 5.10.
1 -
Engine oil replacement (Par. 6.1).
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:
Follow the steps described in Par. 4.6.
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.
12 - Treat non-painted parts with protective products.
If the engine protection is performed according to the
suggestions indicated no corrosion damage should occur.
5.10 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 - Refill the tank with fresh fuel.
5 - Make sure that the oil and the coolant are up to the
maximum level.
6 - Start the engine and keep it idle at minimum speed for a
two about minutes.
7 - Bring the engine to 75% of maximum rated speed for 5 to
10 minutes.
8 - Stop the engine while the oil is still hot
(Par. 6.1), 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. 5.2.
9 - Replace the filters (air, oil, fuel) with original spare parts.
10 - Pour new oil (Par. 4.5) up to the maximum level.
11 - Empty the cooling circuit completely and pour in the new
coolant up to the maximum level (Par. 6.4).
