6.47 Engine conservation
If the engine is to be shut down for a longer period
of time (e.g. over winter), we recommend to apply
the following conserving measures to avoid corro-
sion:
l
Clean the engine, including the cooling sys-
tem: With cold cleansing agent and a water jet
or, even better, with a steam cleaner.
l
Run the engine warm and shut it down.
l
Drain off the still hot engine oil and fill in anti-
corrosion engine oil.
l
Drain off the coolant and fill in system protec-
tion agent.
l
Drain the fuel from the tank, mix it well with
10% anti-corrosion oil and fill it back in.
l
Run the engine for 10 minutes until all lines, fil-
ters, pumps and nozzles with this conserving
mixture and the new engine oil has been dis-
tributed to all parts.
l
Now crank the engine several times (without
ignition) to spray the combustion chambers.
l
Take the V-belts off and spray the grooves of
the V-belts with anti-corrosion oil. Remove the
anti-corrosion oil before resuming operation.
l
Close intake and exhaust openings tightly.
Note
i
Depending on the weather conditions these con-
serving measures will provide protection for ap-
prox. 6 to 12 months.
Before taking the engine back into operation all
conserving oil must be drained off and replaced by
regular engine oil, see chapter "Fuels and Lubri-
cants" according to the API-(MIL)-classification.
Anti-corrosion oils are those that comply with
the specification MIL-L-21260 B or TL 9150-
037/2 or Nato Code C 640/642.
A machine with a conserved engine must be
marked by attaching a clearly visible warning
tag.
