Scania DC09 XPI. Industrial engine. Operator’s manual - part 8
Preparing the engine for storage
9. Detach the fuel pipe at the overflow valve
and connect a return hose to a separate can.
10. Connect and bleed the fuel system.
11. Start the engine and run it at about 1,100 rpm
for 20 minutes.
If the engine has an SCR system and the re-
ductant tank is empty, it is possible to run the
engine for this limited time without damag-
ing the components of the SCR system. This
applies if the engine is run without load.
12. If the engine has an SCR system and the re-
ductant tank is full of reductant: Seal all con-
nections in the SCR system.
13. Remove the rocker covers and lubricate the
valve mechanisms with pushrods and the
valve tappets, as well as the injector mecha-
nism, using a liberal amount of preservative
oil. Refit the rocker covers.
14. Drain the coolant if the engine is not to be
stored with coolant in the system. Plug and
tape all coolant connections if the engine is
to be stored without coolant in the cooling
system.
15. Renew the filter element in the air cleaner.
16. Cover the air intake and exhaust pipe.
17. Spray the outside of the alternator and starter
motor with water-repellent anti-corrosive
oil: CRC 226, LPS1 or equivalent.
18. Spray the outside of bright engine parts, first
with penetrating preservative oil such as
Dinitrol 25B and then with Dinitrol 112 or
the equivalent.
19. Clearly mark the engine with the storage
preparation date, and state that the engine
must not be started or cranked.

Preparing the engine for storage
Batteries
WARNING!
Wear protective gloves and protective goggles
when charging and handling batteries. The bat-
teries contain a highly corrosive acid.
Remove the batteries and trickle charge them at
the battery charging station. This does not apply
to batteries specified as maintenance-free by the
manufacturer.
The same applies to short-term storage, even if
the engine has not been prepared for storage as
above.
Storage
After the preparation, the engine should be
stored indoors in a dry location at room temper-
ature. The engine must be packed in packaging
made of VCI plastic to protect against dust, dirt
and moisture.

Preparing the engine for storage
When the engine is to be taken into
operation again
1. If the engine is equipped with an SCR sys-
tem: Drain and clean the reductant tank and
fill with new reductant.
2. Remove plugs and tape from the coolant
connections, air intake and exhaust pipe.
3. Fill the cooling system with coolant.
4. Drain the preservative oil.
5. Renew the oil filter and fuel filter.
6. Fill with new engine oil.
7. Remove the rocker covers and lubricate the
valve mechanisms with pushrods and the
valve tappets, as well as the injector mecha-
nism, using a liberal amount of oil. Refit the
rocker covers.
8. Drain the preservative fuel from the fuel
manifold.
9. Connect and bleed the fuel system.
10. Wash off any preservative oil on the outside
using white spirit.
