7  Mothballing the turbocharger / 7.2  Taking the engine out of opera-
tion for more than 12 months

© Copyright 2018 . All rights reserved.

HZTL2499_EN

Revision F

December 2018

If the total acid number (TAN) is greater than 2 mg KOH/g, the following
mothballing measures are necessary after taking an engine out of opera-
tion:

u

Dismantle the turbocharger.

u

Clean all parts.

u

Machined, bright surfaces of steel and cast parts must be oiled with
anticorrosive oil.

u

Reassemble complete turbocharger.

Rotor turning in stack draught

If the rotor turns as a result of the stack draught:

u

Install blind flange between compressor casing outlet flange and
charge air duct.

7.2 Taking the engine out of operation for more

than 12 months

If the engine is taken out of operation, the following variants are pos-
sible with regard to the turbocharger:

¡

The turbocharger remains mounted on the engine.

¡

The turbocharger is removed completely.

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 Rotor turning in
stack draught.

If the complete turbocharger is removed:

u

Close all turbocharger openings using wooden covers and paraffin
paper.

Only dry rooms with 40 ... 70 % atmospheric humidity, in which no water
condensation can form, are suitable as storage locations.

Condition of the mothballed turbocharger

u

Check the turbocharger for corrosion once per annum.

u

If there are signs of rust: Clean parts thoroughly and renew protection
against corrosion.
