Guide Blade Actuator Inspection - Mazda Mazda6 Workshop Manual Supplement

Turbine Wheel Inspection
1. Remove the warm up oxidation catalytic converter between the flexible pipe and the turbocharger. (See
EXHAUST SYSTEM REMOVAL/INSTALLATION.)
2. Visually inspect the turbine wheel from view B and verify that all fins are free from damage, cracks or bends.
• If there are damaged fins, cracks or bends, replace the turbocharger.
Note
• To make the inspection easier, set a small
mirror as shown in the figure and use a
penlight.
• If the turbine wheel is interfering with the
turbine housing, it is likely that the fin edges
are cracked, damaged, or bent.
• If the turbine wheel is damaged, check the
following before replacing the turbocharger
to avoid reoccurrence of the problem.
— Foreign material in intake air/exhaust
system.
— Oil pipe clogging.
