Removing the cartridge group
τ Check the lifting gear and fasten it to bearing casing (42001).
τ Disconnect all lines in accordance with the engine builder's instruc-
tions, remove the insulation, remove the turbocharger and compressor
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.
τ Do not touch hot surfaces and heed the warning plate on the turbo-
charger.
τ Wear heat-resistant safety gloves and protective clothing.
τ Allow the turbocharger to cool down before carrying out any work.
Wear safety gloves to protect against thermal hazards.
ϖ The bearing casing is difficult to loosen.
τ 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.
τ It should thus be used alternately on both sides while avoiding ex-
cessive pressure on either side.
