Turbocharger 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 Turbocharg-
ing Service Station.
