Expected exchange intervals
4.3
Rotating components
The recommended replacement intervals for compressor wheels and tur-
bine wheels are defined depending on the operating conditions and based
on the safety concept (SiKo) for rotating parts. These intervals can be
found on the turbocharger rating plate.
Non-rotating components
Depending on the system-specific operating conditions, a distinction is
made between:
€ the replacement interval for the bearing parts and
€ the replacement interval for those non-rotating components that are
exposed to hot gases.
Decisive in this respect are various influencing parameters, which can
drastically shorten the replacement intervals of these parts in extreme
cases.
During the specified periodic service work, the individual components are
inspected for wear and, if necessary, replaced.
