WARNING
Incorrect handling of a cartridge group
The disassembly and assembly of the cartridge group, as well as the assess-
ment of the rotor and bearing parts, requires the expertise of an ABB Tur-
bocharging Service Station. The rotor parts rotate extremely quickly and are
sensitive to unbalance. Incorrect handling of a cartridge group can damage
the turbocharger and cause injuries to persons.
Ensure that the disassembly and assembly of the cartridge group is only
u
carried out by an ABB Turbocharging Service Station.
NOTICE
Specialist knowledge of an ABB Turbocharging Service Station
Assembly and disassembly of the cartridge group and assessment of the ro-
tor and bearing parts requires the specialist knowledge of an ABB Tur-
bocharging Service Station. The rotor parts turn very fast and are very sens-
itive to unbalance.
The rotor and bearing parts must be checked and assessed by an ABB Turbocharging Service
Station. The following work can be carried out as preparation.
Remove turbocharger from engine (see chapter
u
Dismantle the turbocharger and measure the clearances (see chapter
u
ting →70).
Mechanically clean the nozzle ring, the turbine casing and compressor casing (see chapter
u
Periodic maintenance work
Check the nozzle ring, turbine casing and compressor casing for cracks and erosion/cor-
u
rosion.
Application with frequent engine start/stop cycles (Peak shaving)
If the turbocharger is used for the 'Peak shaving' mode with frequent engine start/stop
cycles, the number of successful engine start/stop cycles must be taken into account in ad-
dition to the inspection interval for the bearing parts specified on the rating plate (in oper-
ating hours).
ABB Turbocharging recommends having the rotor and bearing parts, as well as the casing
u
parts on the turbine end, including the nozzle ring, checked and maintained by an ABB
Turbocharging Service Station after 5000 successful engine start cycles.
