Preparing the engine for storage
Preparing the engine for
storage
If the engine is not being used for an extended
period its cooling system, fuel system and com-
bustion chamber and outside must be protected
against rust.
On delivery, the engine is protected by so-called
VCI plastic. Provided that the VCI bag is intact
and has not been removed, the engine can be
stored for 3 years without any action required.
After 3 years, the engine must be preserved again
and the battery must be renewed.
The interval between each new Preparing for
storage is then 24 months and the bag is renewed.
The VCI bag must be inspected at least once a
year. If the plastic is missing or broken, it must
be replaced with a new one immediately.
An alternative to preparing the engine for long-
term storage is to start the engine and warm it up
every 6 months.
Preparation means that the following measures
are taken:
• The engine is cleaned thoroughly.
• Run the engine for a specific period using
special preservative fuel, oil and coolant.
• Otherwise prepare the engine for storage (fil-
ter renewal, lubrication, etc.).
Preservative products
Preservative oil
Use a normal engine oil that meets the require-
ments in this section.
Preservative coolant
Use coolant containing 50% by volume of gly-
col. Example: BASF MPG Glysacorr P113 and
Valvoline Zerex P113 FP.
Ethylene glycol can be fatal if ingested and can
cause skin irritation and eye damage.
Preservative fuel
Preservative fuel must not contain biodiesel.
Even small amounts of 5-10% biodiesel can have
adverse effects on the engine when in long-term
storage.
Long-term storage of diesel, where the diesel
comes into contact with water, may lead to the
growth of micro organisms (bacteria and fun-
gus).
In order to minimise the growth of micro-organ-
isms, preservative fuel should contain the fol-
lowing additives. The additives should be
selected and added by the fuel supplier.
Preservative fuel should comply with the follow-
ing requirements:
• 0% biodiesel.
• Max. sulphur content 50 ppm.
• Max. water content 200 ppm.
• The fuel must contain additives to stop the
growth of micro-organisms.
Reductant
Over time, the water in the reductant evaporates
and there is only urea left. The reductant then be-
gins to crystallise. The reductant tank is not sen-
sitive to crystals, but the ball valves in the
reductant pump may become clogged. However,
note that corrosion or other particles can also
clog the ball valves.
All connections in the SCR system must be
sealed before storage, so that the water in the re-
ductant does not evaporate. The SCR system
should then be stored in a cool location and not
in direct sunlight. If the reductant tank has never
been filled with reductant, it can be stored when
empty for an unlimited time.
When the engine is taken into operation again,
all reductant must be drained and changed. If old
reductant is used, the SCR system will not work.
