Table14: Malfunctions when starting – Vibrations
Rotating parts rubbing
Normal behaviour, not a malfunction
Turbocharger A minimal and uniform wear on the circumference of the rotor components is per-
mitted. This wear can be caused by slight local rubbing against adjacent compon-
ents. This causes the compressor or turbine blades to be somewhat shortened. To
prevent significant loss of efficiency, specific tolerances must be fulfilled.
¡ If there is any doubt about the extent of the rubbing, contact an ABB Tur-
bocharging Service Station.
¡ Have a dimension check carried out by an ABB Turbocharging Service Sta-
tion.
