5.1 
General maintenance work involves regular visual checks and cleaning 
tasks which are intended to ensure the trouble-free functioning of the 
turbocharger. 
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 
 
 
Risk of damage during mechanical cleaning 
If mechanical cleaning is carried out too often, this can lead to damage 
and corrosion on the components. 
 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. 
 
 
To allow you to observe the standard service intervals and to maintain a 
high turbocharger efficiency, ABB Turbo Systems recommends that the 
cleaning procedure be carried out during operation. This allows the 
thermal load of the engine to be kept low while ensuring maximum fuel 
efficiency. 
  Dispose of dirty water and cleaning agents in an environmentally 
compatible manner, professionally and in accordance with valid local 
regulations.
