5.23 Engine conservation
If the engine is to be shut down for a longer pe-
riod of time (e.g. during the winter) we recom-
mend the following conservation measures for
the engine to avoid corrosion:
l
Clean the engine including the cooling system:
with cold cleansing agent or, even better, with
a steam cleaner.
l
Run the engine warm and shut it down.
l
Drain the still warm engine oil and fill in anti-
corrosion engine oil.
l
Drain the fuel from the fuel tank, mix it well with
10% anti-corrosion oil and fill it in again. In-
stead of mixing anti-corrosion oil with the fuel
it is also possible to fill the tank with injection
pump testing oil with anti-corrosive properties
(e.g. Calibration Fluid B).
l
Run the engine for 10 minutes until all lines, fil-
ters, pump and nozzles are filled with the con-
serving mixture and the new engine oil is
distributed to all parts.
l
After running the engine remove the valve cov-
er and spray the rocker chamber with a mix-
ture of diesel fuel and 10% anti-corrosion oil.
After this screw the cover back on.
l
Crank the engine several times by hand (throt-
tle lever in stop position) to spray the combus-
tion chamber.
l
Take the V-belt off and spray the grooves in
the V-belt pulleys with anti-corrosion oil. Re-
move the anti-corrosion oil before taking the
machine back into operation.
l
Close the air intake opening on the air filter
and the exhaust tube.
i
Note
Depending on weather conditions these conserv-
ing measures will provide protection for approx. 6
- 12 months.
The conserving oil must be replaced by engine oil
according to the API- (MIL) classification before
taking the machine into service.
Anti-corrosion oils are those that comply with the
MIL-L-21260 or TL 9150-037/2 resp. Nato Code
C 640/642.

Caution
Mark a machine with a conserved engine by at-
taching a clearly visible warning tag.
