Turbochar-
ger
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 Turbochar-
ging Service Station.
