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.
Comply with the enginebuilder's specifications regarding the selection of lubricating oil
u
and the oil change intervals.
4.1.2 Pre-lubrication
Pre-lubrication must be carried out as follows:
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.
u
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
