Rubbing of rotating parts
Normal behaviour, not a malfunction
Turbochar-
ger
A minimal and uniform wear at the circumference of the rotor components
caused by slight local rubbing against adjacent components is permitted. This
causes the compressor or turbine blades to be somewhat shortened. To pre-
vent 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.
