7.2 Remove the turbocharger

-  Disconnect all gas, air, and oil lines in accordance with the engine manufacturer’s instructions.


The two oil supply channels in the bearing casing are fitted with one orifice each. In order to obtain the required oil pressure, the ∅ of this orifice has been individually adjusted by the engine builder. Whenever these orifices are removed, or if the bearing casing or the complete turbocharger is replaced, it is essential to ensure that the orifice with the correct ∅ is fitted into the oil-conducting oil-inlet channel.

-  Remove the insulating shell from the bearing casing.
Check the lifting equipment.
Secure lifting equipment to the suspension lugs on the bearing casing.

Observe weight of the turbocharger.

During removal, a turbocharger that is not lifted in compliance with regulations may fall, and can cause serious or even fatal injury.
If the bearing casing is not provided with a reinforced suspension lug (lugs are flush with external    diameter of the flange), the complete charger must be secured by the air outlet casing and gas inlet casing.  See following illustration.
-  Select a suitable rope taking into account the weight of the turbocharger.

- Release the fixing screws on the foot.
- Lift the turbocharger from the engine and place it aside.


If the support for the turbocharger is missing or defective, the turbocharger may tip over during installation and removal and can cause serious or even fatal injury.

- Support turbocharger in a suitable location.
- Cover oil connector.
