15.1.6 Operation with damaged turbocharger
In case of a serious breakdown of the turbocharger, and if the
situation do not allow the immediate repair or exchange of the
turbocharger, the engine can temporarily be operated up to about
20 % of the nominal output of the engine with the turbocharger
rotor removed.
For removing of the rotor, see instructions in the turbocharger
manual.
It is to be noticed that the blocking of the rotor is not recom-
mended as the engine will suffer less with the rotor completely
removed.
Caution! As the turbocharger is out of function the thermal load on the
engine components will increase. Therefore the exhaust gas
temperatures must be carefully watched during operation with
removed rotor.
