Axial Clearance
- Remove turbocharger assembly from engine. Remove wastegate activating rod clip and rod from activating arm.
- Remove 5 bolts connecting turbine outlet elbow to housing. One bolt is located inside elbow housing. Remove elbow from turbocharger assembly.
- Attach a dial indicator at the turbine end of the turbocharger assembly so the tip rests on the end of the turbine wheel assembly. See Fig. 5 .
- Manually move the compressor wheel and turbine wheel assembly alternately away from and toward the turbine end of turbocharger assembly. Note the travel of the shaft shown by dial indicator.
- Repeat procedure until exact maximum travel has been indicated. If maximum thrust bearing clearance is not within 0.001 - 0.003", replace turbocharger assembly.
- If turbocharger meets all specifications, remove test equipment, reinstall by reversing removal procedure and tighten bolts to specification.
