12 Mothballing the turbocharger
12.2 Taking the engine out of operation for more than
12 months
If the engine is taken out of operation, the following variants are possible with regard to the
turbocharger:
 Turbocharger remains attached to the engine.
 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 ope-
ration 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 indi-
vidual parts:
Seal all openings of the turbocharger with paraffin paper and wooden lids.

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
Check the turbocharger parts annually for corrosion.

If there are signs of rust: Thoroughly clean parts and renew corrosion protection.
