u Apply penetrating oil to thread of stud (02) and nut and let it work in.
Do not apply penetrating oil to the pressure screws of the clamping nut(B).
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.
u If present: Detach the support(61301) from the engine support.
Depending on the bracket version(04), positioning pins(05) can be used for positioning and
safeguarding against wrong fitting of the turbocharger. Therefore the turbocharger must al-
ways be removed from and installed on the bracket vertically.
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.
