Replacement intervals for turbocharger
components
The recommended replacement intervals for the compressor and turbine
wheels due to stressing caused by centrifugal forces and load cycles are
calculated under consideration of the operating conditions while applying
the safety concept for rotating components. They can be found on the
turbocharger rating plate. Non-calculable influencing parameters can
shorten recommended rotor replacement intervals,

.
The expected replacement intervals for non-rotating components and
bearing parts greatly depend on system-specific operating conditions,
Influencing parameters
When the specified, periodic inspections are carried out, the individual
components are inspected for wear and tear and replaced if necessary. In
this way, trouble-free operation is ensured.
The following parameters influence the replacement periods for
turbocharger components:
Parameters influencing bearing parts:
 Poor lubricating oil quality (lubrication oil filter system, condition of
lubricating oil)
 Unusual loads (vibration, start / stop frequency)
 Impermissible state of rotor unbalance
Parameters influencing non-rotating components exposed to exhaust gas
 Fuel quality (Gas, MDO, HFO)
 Loading profile (thermal load changes, number of starts/stops)
 Temperature level of exhaust gas
 Turbine cleaning frequency
 Procedure for turbine cleaning
Parameters influencing rotating components exposed to exhaust gas
 Fuel quality (Gas, MDO, HFO)
 Turbine cleaning frequency
 Procedure for turbine cleaning
 Loading profile
