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 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.
