3.1 Oil supply
3.1.1 Introduction
In all operating states, a functioning and carefully executed oil supply is an important
prerequisite 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.
3.1.2 Pre-lubrication
Pre-lubrication must be carried out as follows:
 Switch on the oil pump.
 Build up oil pressure (see Table 6).
 Do not exceed a pre-lubrication time of 2 minutes.
 Start the engine.
 Let the oil pump run until the pump driven by the engine generates sufficient pressure.
3.1.3 Oil filtering
Lubricating oil filtering with a filter mesh width of ≤ 0.034 mm is sufficient for this turbocharger.
3.1.4 Oil pressure
Comply precisely with the oil pressure before the turbocharger for trouble-free operation.
The admissible values are specified in chapter Monitoring operation [➙ 29].
