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.
Disconnect all pipes according to the instructions of the enginebuilder.

u
cable on the turbocharger. This protects the plug from being crushed.
