CAUTION

Rotation of the rotor in the stack draught

The rotor can rotate in the stack draught. If the bearings are not lubricated,

this can result in wear.

u Install blind flange between gas outlet casing and exhaust gas pipe.

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 op-

eration for up to 12months →94, subsection Rotor turning in stack draught.

If the complete turbocharger is removed or the turbocharger is assembled again from the

individual parts:

u 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

u Check the turbocharger parts annually for corrosion.

u If there are signs of rust: Thoroughly clean parts and renew corrosion protection.
