The turbocharger casing remains mounted on the engine, but the ro-
tor and the bearing parts are removed and stored separately.

The turbocharger is removed completely, either as a whole or in indi-
vidual parts.
See the section Taking out of operation for up to 12 months, under
Mothballing measures, for the measures always necessary when moth-
balling turbocharger parts.
If the turbocharger remains mounted on the engine, refer to the section
Taking out of operation for up to 12 months, under Rotating the rotor in
stack draught.
If the entire turbocharger is removed or if the turbocharger is re-as-
sembled next to the engine using the individual parts:
Close all turbocharger openings using wooden covers and paraffin
u
paper.
Suitable storage locations are only dry rooms where the relative humid-
ity is between 40 to 70 % and no condensation can form.
