4.2.4
Service work every 15000 … 16000 hours
Inspection and assessment of the rotor and bearing parts as well as re-
placement of the variable turbine geometry module with a CPEX variable
turbine geometry module must be carried out by an ABB Turbocharging
Service Station.
w
It is recommended that the turbocharger is inspected once a year, but
at least after every 15000 operating hours.
u
Disassemble turbocharger
u
Clearance measurement
u
Clean the turbine and compressor wheels and inspect for damage
u
Clean the turbine and compressor casings and inspect for any cracks
and erosion or corrosion
u
Clean bearing casing and blow air through oil ports
u
Inspect and assess sealing air lines
u
Inspect and assess rotor and bearing parts
u
Have the variable turbine geometry module overhauled by ABB Tur-
bocharging. ABB Turbocharging Service Stations have variable turbine
geometry modules replaced with overhauled ones as part of the CPEX
(Customer Part Exchange) programme.

4.3 Replacement intervals for turbocharger
components
Rotating components
The recommended replacement intervals for the compressor and turbine
wheels due to stress caused by centrifugal forces and load cycles are cal-
culated under consideration of the operating conditions while applying
the safety concept for rotating components. They can be found on the
