Foreword to maintenance

Maintenance work includes regular visual controls and cleaning operations which are intended
to ensure the trouble-free functioning of the turbocharger.
In this process, the exterior condition and the degree of contamination of the components on
which maintenance work is to be performed are determined.
The maintenance points described here are differentiated as follows:
 Cleaning during operation:
– Compressor
– Turbine and nozzle ring.
 Mechanical cleaning of individual components:
– Filter silencer
– Casings, diffuser, nozzle ring
– Cartridge group: Compressor, turbine
Cleaning method
To allow you to observe the standard service intervals and to maintain a high
turbocharger efficiency, ABB Turbo Systems recommends that compressor
NOTICE
and turbine be cleaned during operation. This allows the thermal load of the
engine to be kept low while ensuring maximum fuel efficiency.
Risk of damage during mechanical cleaning
If mechanical cleaning is carried out too often, this can lead to damage and
corrosion on the components.
CAUTION
If cleaning during operation is not sufficient to achieve acceptable values

regarding thermal load and engine performance, mechanical cleaning of
certain spots can be carried out.
Perform mechanical cleaning, especially of the cartridge group, only once

within the service interval.
Dirty water and cleaning agents must be disposed of in an environmentally compatible, pro-

fessional way and in compliance with locally applicable regulations.
