4.1 Oil supply
4.1.1 Introduction
In all operating states, a functioning and carefully executed oil supply is an important pre-
requisite for trouble-free operation of the turbocharger.
The lubrication of the turbocharger is usually carried out with oil from the engine oil circula-
tion.
u Comply with the enginebuilder's specifications regarding the selection of lubricating oil
and the oil change intervals.
4.1.2 Oil filtering
Filtering the lubricating oil with a filter mesh width of ≤0.034mm is sufficient for this tur-
bocharger.
4.1.3 Oil pressure
Comply precisely with the oil pressure before the turbocharger for trouble-free operation.
Different oil pressures must be taken into account here for different operating states, such
as, for example, idling mode and when the engine is started.
The admissible values are specified in chapter Monitoring operation →45.
4.1.4 Starting the engine for the first time after a
turbocharger or engine overhaul
When starting the engine for the first time after a turbocharger or engine overhaul, proceed
as follows:
u Switch on the pre-lubrication pump.
u Build up oil pressure.
u Do not exceed a pre-lubrication time of 2minutes.
u Start the engine.
u Let the pre-lubrication pump run until the pump driven by the engine generates sufficient
pressure.
