2.2 Removing the turbocharger
The gas outlet casing (61001) can remain fitted in the exhaust gas pipe if the locking nuts
are accessible. Otherwise the complete turbocharger unit including gas outlet casing must
be removed.
u Disconnect all pipes according to the instructions of the enginebuilder.
u If present: Loosen and remove the compressor wheel cooling connection. Close the com-
pressor wheel cooling opening with a screw plug(01).
u If present: Disconnect the plug to the speed sensor (86505) and secure the rolled-up
cable on the turbocharger. This protects the plug from being crushed.
