3.1 Oil supply
3.1.1 Introduction
In all operating states, a functioning and carefully executed oil supply is an important prerequi-
site for trouble-free operation of the turbocharger.
The lubrication of the turbocharger is usually carried out with oil from the engine oil circulation.

Follow the enginebuilder's specifications on the selection of the lubricating oil and the oil
change intervals.
For more information on the oil supply, refer to Chapter Oil pressure, oil temperature [➙ 21].
3.1.2 Oil filtering
Filtering of the lubricating oil with a filter mesh width of ≤ 0.050 mm is sufficient for the turbo-
charger.
3.1.3 Oil pressure
Comply precisely with the oil pressure before the turbocharger for trouble-free operation.
If the oil pressure at the inlet of the turbocharger is too high, it can be reduced with a throttle
valve. The throttle valve is normally already fitted on the turbocharger and has been correctly
set by the enginebuilder. This takes place either during the trial run on the engine test bed or
during the trial phase of the system.
If the oil pressure values are outside the admissible range during normal operation, you must
contact the enginebuilder.
3.2 Inspection procedures
3.2.1 Introduction
Inspection procedures include preventative visual controls, monitoring and measuring work
before and during commissioning. Inspection procedures enable changes to the turbocharger
to be detected. Engine damage can be prevented.
