Put the cartridge assembly in Tool (E) and use a press (if necessary) to remove compressor wheel (6) from the turbine wheel and shaft assembly. Do not let the turbine wheel and shaft assembly fall during removal of the compressor wheel from the turbine wheel and shaft. 5. Remove seal ring (7) and shroud (8) from turbine wheel and shaft assembly (9). 6. Bend the tabs of the locks from bolts (10)
