5.32 Engine conservation
If the engine is to be shut down for a longer period
of time (e.g. during winter) we recommend the fol-
lowing conservation measures for the engine to
avoid corrosion:
l Clean the engine, including the cooling system
with cold cleansing agent and a water jet or,
even better, with a steam jet.
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-
ter, pump and nozzles are filled with the con-
serving mixture and the new engine oil is
distributed to all parts.
l After this test run remove the cylinder head
covers and the lateral cover of the injection
pump, spray the rocker chambers and the
spring chamber in the injection pump with a
mixture of diesel fuel with 10% anti-corrosion
oil. Reassemble hoods and covers.
l Crank the engine several times by hand (with-
out ignition) in order to spray the combustion
chamber.
l Take the V-belt off and spray the grooves in
the pulleys with anti-corrosion oil. Remove the
anti-corrosion oil before taking the machine
into operation.
l Close the air intake opening on the air filter
and the exhaust opening.
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 operation. Refer to the
section "Fuels and lubricants".
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.
Mark a machine with a conserved engine by at-
taching a clearly visible warning tag.
