¡
The casings of the turbocharger remain attached to the engine, the rotor and bearing
parts are dismantled by an ABB Turbocharging Service Station and stored separately

The turbocharger is completely removed, either as a whole unit or in individual parts
For the measures always necessary for preparing the turbocharger parts for mothballing,
see section Taking the engine out of operation for up to 12 months, subsection Preparations
for mothballing.
If the turbocharger remains attached to the engine, see section Taking the engine out of op-
eration for up to 12 months, subsection Rotation of the rotor in the stack draught.
If the complete turbocharger is removed or the turbocharger is assembled again from the
individual parts:
Seal all openings of the turbocharger with paraffin paper and wooden lids.
u
Only dry rooms with 40 ... 70 % atmospheric humidity, in which no water condensation can
form, are suitable as storage locations.
State of the mothballed turbocharger
