Removing the cartridge group
u Check the lifting gear and fasten it to bearing casing (42001).
If provided
u Disconnect all lines in accordance with the engine builder's instruc-
tions, remove the insulation, remove the turbocharger and com-
pressor casing together with the filter silencer (also see the previous
chapter).
WARNING
Risk of burning
Touching hot surfaces or contact with hot operating materials can lead
to serious burns.
u Do not touch hot surfaces and heed the warning plate on the tur-
bocharger.
u Wear heat-resistant safety gloves and protective clothing.
u Allow the turbocharger to cool down before carrying out any work.
Wear safety gloves to protect against thermal hazards.
w The bearing casing is difficult to loosen.
u Use the press-off tool (90042) against the turbine casing to press off
the bearing casing (see the following illustration).
CAUTION
Axial force
The press-off tool can generate a high axial force and, if it is not used
properly (too much pressure on one side), it can damage the rotor.
u It should thus be used alternately on both sides while avoiding ex-
cessive pressure on either side.
