Troubleshooting
Malfunctions when starting
Sluggish start-up
Possible causes
Turbocharger Turbocharger contaminated
Damaged bearing
Rubbing rotor
Foreign object in turbocharger
Vibrations
Possible causes
Turbocharger Rotor unbalance
Damaged turbine or compressor
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.
