TURBOCHARGER SEVEN-STEP INSPECTION

8
The following inspection procedure is recommended for
systematic failure analysis of a suspected failed
turbocharger. This procedure will help to identify when a
turbocharger has failed, and why it has failed so the
primary cause of the failure can be corrected.
Proper diagnosis of a non-failed turbocharger is important
for two reasons. First, identification of a non-failed
turbocharger will lead to further investigation and repair of
the cause of a performance complaint.
Second, proper diagnosis eliminates the unnecessary
expense incurred when a non-failed turbocharger is
replaced.
The seven recommended inspection steps, which are
explained in detail on following pages, are:
Compressor Housing Inlet and Compressor Wheel.
Compressor Housing Outlet.
Turbine Housing Inlet.
Turbine Housing Outlet and Turbine Wheel.
External Center Housing and Joints.
Internal Center Housing.
Turbocharger Bench Test.
