3.1 Oil supply
3.1.1 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.
3.1.2 Pre-lubrication
Pre-lubrication must be carried out as follows:
u
Switch on the oil pump.
u
Build up oil pressure (see Table 6: Lubricating oil pressure at oil inlet before turbocharger
→ 25) .
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.
3.1.3 Oil filtering
Filtering the lubricating oil with a filter mesh width of ≤ 0.034 mm is sufficient for this tur-
bocharger.
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 → 25 .
