Version with turbine cleaning:
CAUTION
Turbocharger damage resulting from the cleaning nozzle breaking off
Incorrect assembly of the cleaning nozzle (51301) can damage the thread of
the turbine casing. The cleaning nozzle (51301) can be plastically deformed
when screwing in the screw connection (02) and during subsequent opera-
tion. Reuse of the cleaning nozzle after loosening the screw connection (02)
can lead to a water leak or the cleaning nozzle breaking off and thus destroy
the turbine.
Only loosen the screw connection (02) if the cleaning nozzle (51301) needs
u
to be replaced.
If the screw connection (02) has been loosened, a new cleaning
u
nozzle (51301) must be installed and the screw connection must be refit-
ted. Observe the specified tightening torque from the supplier of the
screw connection.
Components (01/02) are not included in the Turbo Systems scope of delivery.

be removed.
