An orifice plate for adjusting the oil pressure is fitted in each of the two
oil inlet channels in the bearing casing. When the cartridge group, the
bearing casing or the turbocharger is fitted to the engine, it must be en-
sured that the orifice plates that are specified for the turbocharger have
been installed in the two oil inlet channels.
Check correct installation of oil orifice plates.
