Notes on cleanliness for Common Rail
engines
Special requirements with respect to cleanliness in
the fuel system do apply for commissioning, mainte-
nance and repair work, particularly for engines with
the Common Rail System. Contamination like dirt,
welding residues or similar can lead to the failure of in-
dividual components and adversely affect engine op-
eration.

l
Spare parts should be left in their original packaging
as long as possible and should only be unpacked
just before use.
l
When parts are unpacked any connections must be
closed with suitable plugs or caps, in order to pre-
vent (Fig. 1) contamination of hose connections. If
e.g. fuel hoses are connected to one side, while the
second side cannot yet be connected, there is a
danger of dirt entering into the system. The free
connection must in this case also be appropriately
closed.
Notes and measures to be applied before starting
work in the fuel system
l
The fuel system must be closed. Visual examination
for leaks / damage in the fuel system.
l
Before starting work in the fuel system clean the
complete engine and the engine compartment with
the system still closed.
l
The engine should be dry before work is started in
the fuel system.
l
Blow drying with compressed air is only permitted
while the fuel system is still closed.
l
When using steam cleaning equipment cover con-
trol unit, cable plugs, all other electrical connections
and the generator beforehand and do not expose
these items to the direct steam jet.
l
Electrical plug connections must be plugged in dur-
ing jet cleaning.
l
Remove loose parts (e.g. paint scales that may
have come off during assembly work) with an indus-
trial vacuum cleaner or any means of extraction.
l
Vacuum cleaning equipment must generally be
used for cleaning when the fuel system is open.
l
Perform work on the fuel system only in a clean en-
vironment (no dust, no grinding or welding work).
Avoid draughts (dust). The workshop floor must be
cleaned at regular intervals. No brake or power test
stand should be present or operated in the same
room.
l
Air movements, which could swirl up dust, such as
brake repairs or starting of engines, must be strictly
avoided.
l
For work, such as disassembly and assembly of de-
fective hydraulic components in the Common Rail
System, it is strongly recommended to set up a sep-
arate workshop area, i.e. an area which is spatially
separated from all other areas (general vehicle re-
pairs, brake repairs).
l
No general machine tools should be operated in this
room.
l
Periodic cleaning of this workshop area is obligato-
ry, draughts, ventilation system and heating blow-
ers must be minimized.
l
Engine compartment area where dirt particles could
come loose, should be covered with new, clean foil.
l
Working means and tools must be cleaned before
being used for work. Use only tools without dam-
aged chromium coating, or tools without chromium
coating.
Notes and measures to be applied during work in
the fuel system
l
Wear clean working clothes.
l
Use only lint-free cleaning cloths for work in the fuel
system.
l
Remove loose parts (e.g. paint scales that may
have come off during assembly work) with an indus-
trial vacuum cleaner or any means of extraction.
Vacuum cleaning equipment must generally be
used for cleaning when the fuel system is open.
l
Working means and tools must be cleaned before
being used for work. Use only tools without dam-
aged chromium coating, or tools without chromium
coating.
