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 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.

ing materials and supplies.

u Wear personal protective equipment (PPE) according to the material

safety data sheet.

u Comply with local legislation.

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.
