Damaged bearing 
 
Rubbing of rotating parts 
 
Normal behaviour, no malfunction 
Turbocharger  Minor uniform wear around the periphery of rotor components, 
caused by slight local rubbing of adjacent components, is per-
missible. The compressor blades and turbine blades are then 
shortened somewhat. Certain tolerances must be observed to 
avoid a significant loss of efficiency. 
  If there is any doubt about the extent of rubbing, then an ABB 
Turbocharging Service Station must be contacted. 
  Have a dimension check carried out by an ABB Turbocharg-
ing Service Station.
