Removing the turbocharger

Removing the turbocharger
Disconnect all gas, air and oil lines in accordance with engine manu-

facturer's instructions.
Oil orifice plates
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.

on the insulation). The lifting gear around the gas inlet casing serves to
align the turbocharger horizontally.

the insulation on the gas inlet casing. Leave any remaining insulation
on the turbocharger.
