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 re-
quired under the following conditions:
¡
Acid number (TAN) < 2 mg KOH/g
¡
The engine lubricating oil is replaced by a preservative oil and circulated with the pre-lub-
rication pump before the engine is taken out of operation. Residues of old engine oil are
flushed away in this way and the bearing parts are largely protected against corrosion.
Preparations for mothballing
WARNING
Handling operating materials and supplies
Swallowing or inhaling vapours of operating materials and supplies or con-
tact with them may be harmful to health.
u
Do not breathe in these substances and avoid contact with the skin.
u
Ensure proper ventilation.
u
Observe the information in the material safety data sheet for the operat-
ing materials and supplies.
u
Wear personal protective equipment (PPE) according to the material
safety data sheet.
u
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 the engine out of operation:
u
Dismantle the turbocharger.
u
The rotor and bearing parts must be dismantled and subsequently refitted by an ABB Tur-
bocharging Service Station.
u
Clean all parts.
u
Coat plain surfaces of steel and cast parts with anticorrosive oil.
