Oil supply

5.1.1 Introduction
In all operating states, a functioning and carefully executed oil supply is an important prerequi-
site for trouble-free operation of the turbocharger.
The lubrication of the turbocharger is usually carried out with oil from the engine oil circulation.
The directives of the enginebuilder on the selection of the lubricating oil and the oil change

intervals must be followed.
5.1.2 Pre-lubrication and post-lubrication
Pre-lubrication
Pre-lubrication must be carried out as follows:
Switch on the oil pump.

Build up oil pressure (see Table 5).

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.

Post-lubrication
 Post-lubrication is not required and not recommended for water-cooled bearing casings.
 For oil-cooled bearing casings, post-lubrication is mandatory for 15-20 minutes if the turbi-
ne inlet temperature (t
– 550 °C with insulated casing
– 600 °C with non-insulated casing
At temperatures below the specified values, post-lubrication for 10 minutes is recom-
mended.
Observe the oil pressure specified for post-lubrication (see Table 5).
