General
Engines contain the following kinds of corrosi-
on protection
z interior corrosion protection
z Exterior corrosion protection
The following corrosion protection work may
only be carried out by persons familiar with it
and instructed in the potential dangers. Due to
the following corrosion protection measures
af-
ter shutting down the engine
the require-
ments for 12 month protection are met. If these
measures are deviated from by exposing the
corrosion-protected engines or parts to unfa-
vourable conditions (installation outdoors or
storage in damp, badly aired places) or dama-
ge to the corrosion protection layer, a shorter
corrosion protection duration is to be expected.
The engine corrosion protection should che-
cked about every 3 months by opening the co-
vers. If corrosion is detected, the corrosion
protection should be renewed. At the end of
the corrosion protection work the crank drive
may no longer be turned so that the corrosion
protection agent in the bearings, bearing liners
and cylinder liners is not scraped off.Before
operating a corrosion protected engine, the
corrosion protection must be removed.
interior corrosion protection
Interior corrosion protection is always provided
by wetting of the walls with the implemented
corrosion protection agent in a corrosion pro-
tection running of the engine. The corrosion
protection ( run can be performed once to pro-

tect the different systems.
Fuel system
z Fill the fuel tank with a mixture of:
– 90% distilled fuel
– 10% corrosion protection oil SAE 20W-20
z Perform a corrosion protection run with no
load for at least 5 minutes.
Lubricating oil system
z Drain lubricating oil from warm engine.
z Thoroughly clean oil tray, cylinder head with
rocker arms, valves, valve springs with die-
sel fuel or cleaning agent.
z Fill the engine with corrosion protection oil
SAE 20W-20 up to the MAX mark and per-
form a corrosion protection run for at least 5
minutes so that all the components of the lu-
bricating oil system are wetted or all acces-
sible parts are wetted with corrosion
protection oil and pump corrosion protection
oil through the engine with a separate pump
until all bearings and bearing liners are wet-
ted.
Air compressor
With a mounted air compressor a corrosion
protection agent should be sprayed into the air
compressor intake system after switching off
the engine until the agent visibly emerges from
the adapter.
Cooling system
Depending on the series the engines are
equipped with cooling air, cooling oil or cooling
fluid system (cooling water with cooling system
protection agent).See the chapter Exterior cor-
rosion protection for the cooling air system.In
engines of the oil-cooled series the circulating
lubricating oil serves simultaneously for coo-
ling. The cooling chambers are protected auto-
matically against corrosion with the lubricating
oil system.If a coolant with corrosion protection
properties is poured into liquid-cooled engines,
no further action is necessary after draining.
z If not, the coolant must be drained and, to
ensure the formation of a covering layer on
the inside surfaces of the cooling system, a
corrosion protection run performed with a
mixture of:
– 95% treated water
– 5% corrosion protection agent
z The duration of the corrosion protection run
and the concentration of the corrosion pro-
tection agent are specified by the manufac-
turer of the corrosion protection agent.
z Then drain the coolant.
Air intake pipes
After the corrosion protection run, remove the
cylinder cover and deinstall injectors. The re-
spective piston must be set to LDC.
z The accessible part of the cylinder liner
should be coated with corrosion protection
oil with a spray lance through the opening.
z Spray corrosion protection oil SAE 20W-20
into air intake pipe.
– Oil drips in lines are not permissible and
must be sucked off if necessary.
