CONDITION:
Compressor wheel comes in contact with compressor housing
CAUSE:
Any contact of the compressor contour is similar to the contact on the turbine housing and results from worn or failed shaft bearings.
RECOMMENDATION:

If wheel is making contact on only one side, either bent shaft or imbalance. Be sure to determine primary cause before replacement of the turbocharger.
CONDITION:
Compressor wheel contact at only one location on the housing.
CAUSE:
During assembly of the turbocharger to the engine, the clamp which secures the compressor housing to the center section was not properly positioned.
RECOMMENDATION:
DO NOT REUSE:
Prior to installing any turbocharger to an engine, be sure that the housing is properly seated and the clamp is tightened to the torque specification in the service manual.
