Oil orifice plate
An orifice plate is fitted in each of the two oil inlet channels in the
bearing casing. In order to obtain the required oil pressure, the diameter
of this orifice plate was individually adjusted by the engine builder.
Whenever these orifice plates are removed, or if the bearing casing, the
cartridge group or the complete turbocharger is replaced, make
absolutely sure that the orifice plate with the correct diameter is fitted in
the oil inlet channel in which the oil flows.
