C Position of expansion sleeves
Treat the stud (02) and nut with penetrating oil on the thread and let it work in.
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.
If present: Loosen support (61301) from engine support and remove.
NOTICE
Safeguard against wrong fitting (only for water-cooled bearing casings)
Depending on the bracket version (04), two positioning pins (05) can be
used for positioning and safeguarding against wrong fitting of the
turbocharger. Therefore the turbocharger must always be removed from and
installed on the bracket vertically.
