Mothballing the turbocharger

12 Mothballing the turbocharger
12.1 Taking the engine out of operation for up to
12 months
State of the engine lubricating oil
The turbocharger normally remains attached to the engine. The measures to be taken for
mothballing of the turbocharger depend on the state of the lubricating oil:
 If the acid number (TAN) is less than 2 mg KOH/g, no measures need to be taken.
 If the engine lubricating oil is replaced with a preservative oil and circulated with the pre-
lubrication pump before the engine is taken out of operation, no measures need to be ta-
ken either. Residues of old engine oil are flushed away in this way and the bearing parts
are largely protected against corrosion.
Preparations for mothballing
If the acid number (TAN) is greater than 2 mg KOH/g, the following mothballing measures are
necessary after taking the engine out of operation:
Dismantle the turbocharger.

The rotor and bearing parts must be dismantled and subsequently refitted by an ABB Tur-

bocharging Service Station.
Clean all parts.

Coat plain surfaces of steel and cast parts with anticorrosive oil.

Fit turbocharger completely.

Rotation of the rotor in the stack draught
If the rotor turns as a result of the stack draught:
Install a blind flange between the outlet flange of the compressor casing and the charge air

duct.
