Preparing the engine for storage
Preparations for storage
Use a suitable container. Used oil, coolant and
reductant must be disposed of as specified in na-
tional and international laws and regulations.
Do not remove the injectors.
1. Remove plugs and tape from the coolant
connections, air intake and exhaust pipe.
2. Drain the oil.
3. Renew the oil filter and fuel filter.
4. Clean the centrifugal oil cleaner.
5. Fill with engine oil to the minimum level on
the oil dipstick.
6. Drain and flush the cooling system of any old
coolant.
7. Top up with preservative coolant.
8. Mix preservative fuel in a can. Detach the
fuel pipe at the feed pump suction pipe and
connect a hose from the can.
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.
