Protecting the engine against corrosion Transport and storage

General
Engines contain the following types of corrosion protection:
z
Interior corrosion protection
z
Exterior corrosion protection
The following measures for corrosion protection
af-
ter taking the engine out of operation
meet the re-
quirements for 12 months corrosion protection.
The following corrosion protection work may only be
carried out by persons familiar with it and instructed
in the potential dangers.
If these measures are deviated from by exposing the
corrosion-protected engines or parts to unfavourable
conditions (installation outdoors or storage in damp,
badly aired places) or damage to the corrosion protection layer, a shorter corrosion protection duration
is to be expected.
The engine corrosion protection should be checked
about every 3 months by opening the covers. 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

by wetting of the walls with the implemented corrosion protection agent in a corrosion protection
run of the engine.
z
The corrosion protection run can be performed
once to protect 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 lube oil tray, cylinder head with
rocker arms, valves, valve springs with diesel
fuel or cleaning agent.
z
Fill the engine with corrosion protection oil SAE
20W-20 up to the MAX mark and perform a corrosion protection run for at least 5 minutes so
that all the components of the lubricating oil system are wetted or wet all accessible parts with
corrosion protection oil and pump corrosion protection oil through the engine with a separate
pump until all bearings and bearing liners are
wetted.
Air compressor
z
If a compressor is installed, a corrosion protection agent must be sprayed into the compressor

suction system after shutting down the engine
until it emerges visibly from the pressure nozzle.
Cooling system
z
Depending on the series the engines are
equipped with cooling air, cooling oil or cooling
fluid system (cooling water with cooling system
protection agent).
z
Cooling air system, see the Exterior corrosion
protection section.
z
In engines of the oil-cooled series the circulating
lubricating oil serves simultaneously for cooling.
The cooling chambers are protected automatically against corrosion with the lube oil system.

z
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 protection
agent are specified by the manufacturer of the
corrosion protection agent.
z
Then drain the coolant.
