Protecting the engine
82
Close off all openings on the engine (e.g.
R
on the charge-air distributor, exhaust etc.)
with an oil-soaked rag.
Drain off the coolant completely for
R
engines that have been removed. Unscrew
the coolant drain plug on the crankcase to
do so. When screwing in the coolant drain
plug, observe the tightening torque.
Relieve the tension in the poly-V-belt. The
R
poly-V-belt can remain in place.
If the engine has been filled with coolant,
R
the engine cooling system must first be fil-
led with water. It must then be filled with a
mixture of water and improver compliant
with Sheet No. 311.0. Coolant without anti-
freeze protection compliant with
Sheet No. 312.0 may also be used.
Protective treatment for 12 to 36
months
Carry out all measures in "Protective treat-
ment for up to 12 months". The fuel system,
combustion chambers and air compressor
also require protective measures.
Carrying out protective measures for
the fuel system
X
Start the engine and allow it to run for
15 - 30 minutes at approximately
900 rpm.
X
Completely fill the fuel tank with diesel fuel.
Carrying out protective measures for
the combustion chambers
Only carry out protective measures for the
combustion chambers when the engine is
cold (coolant temperature under 50 †).
Only use initial operation oil compliant with
Sheet no. 225.6 for the protection of the
combustion chambers.
X
Detach the charge-air distributor from the
cylinder heads.
X
Briefly press the start button on the engine.
At the same time, pour approximately
3
15 to 20 cm
of initial operation oil into
each cylinder.
Carrying out protective measures for
the air compressor
Carry out the protection of the air compressor
at the same time as the combustion chamber
protection.
X
On the air intake side of the compressor,
pour a maximum of 5 cm
tion oil compliant with Sheet No. 225.6 into
the compressor.
After protective measures
X
Refit all removed engine parts. Observe the
tightening torques.
! After protective measures are complete,
the engine must not be started again.
Protective treatment for longer than
36 months
For protective treatment for periods exceed-
ing 36 months, repeat the protection meas-
ures as in "Protective treatment for 12 to
36 months".
X
Drain off engine oil that has been added.
The oil filter does not have to be replaced.
