Rotating parts rubbing
Normal behaviour, not a malfunction
Turbochar-
ger
A minimal and uniform wear on the circumference of the rotor components is
permitted. This wear can be caused by slight local rubbing against adjacent com-
ponents. 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.
