Mothballing the turbocharger

11 Mothballing the turbocharger
11.1 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 the turbocharger depend on the state of the lubricating oil. No measures are nec-
essary under the following conditions:
 Acid number (TAN) < 2 mg KOH/g
 Before taking out of operation, the engine lubricating oil is replaced with a preservative oil
and circulated with the pre-lubrication pump. Residues of old engine oil are flushed away
in this way and the bearing parts are largely protected against corrosion.
Preparations for mothballing
Handling operating materials and supplies
Swallowing or inhaling vapours of operating materials and supplies or con-
tact with them may be harmful to health.
WARNING
Do not breathe in these substances and avoid contact with the skin.

Ensure proper ventilation.

Observe the information in the material safety data sheet for the operating

materials and supplies.
Wear personal protective equipment (PPE) according to the material safe-

ty data sheet.
Comply with local legislation.

Wear safety goggles.
Wear safety gloves to protect against chemical hazards.
Wear a respiratory mask to protect against gases.
If the acid number (TAN) is greater than 2 mg KOH/g, the following mothballing measures are
necessary after taking out of operation:
Remove turbocharger (see chapter Removing and Installing [➙ 11]).

Dismantle turbocharger (see chapter Dismantling and fitting [➙ 59]).

The rotor and bearing parts must be dismantled and refitted by an ABB Turbocharging

Service Station.
Clean all parts.

Coat the plain surfaces of steel and cast parts with anti-corrosive oil.

Fit turbocharger completely.
