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 Pre-lubrication
Pre-lubrication must be carried out as follows:
u Switch on the oil pump.
u Build up oil pressure.
u Do not exceed a pre-lubrication time of 2minutes.
u Start the engine.
u Let the oil pump run until the pump driven by the engine generates sufficient pressure.
4.1.3 Oil filtering
Filtering the lubricating oil with a filter mesh width of ≤0.034mm is sufficient for this tur-
bocharger.
4.1.4 Oil pressure
Comply precisely with the oil pressure before the turbocharger for trouble-free operation.
The admissible values are specified in chapter Monitoring operation →45.
