Disassembly and assembly
Disassembling and assembling
turbocharger
Installing compressor casing
Refit wall insert (77000) and O-ring (77005) in reverse order.
O-rings
Used O-rings must always be replaced with new ones. O-rings are only
available as a set (see chapter Spare parts).
Install compressor casing in reverse order.
Thoroughly clean fastening strips (72012) before fitting them.
Removing the cartridge group
Check the lifting gear and fasten it to bearing casing (42001).
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).
Risk of burning
Touching hot surfaces or contact with hot operating materials can lead
to serious burns.
Do not touch hot surfaces and heed the warning plate on the turbo-
charger.
Wear heat-resistant safety gloves and protective clothing.
Allow the turbocharger to cool down before carrying out any work.
Wear safety gloves to protect against thermal hazards.
The bearing casing is difficult to loosen.
Use the press-off tool (90042) against the turbine casing to press off
the bearing casing (see the following illustration).
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.
It should thus be used alternately on both sides while avoiding ex-
cessive pressure on either side.
