Rubbing of rotating parts

Normal behaviour, not a malfunction

Turbocharger A slight amount of 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 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.
