Before you start
- Turbocharger bearing failures can cause large quantities of oil to enter the air inlet and exhaust systems.
Procedure
- Remove exhaust outlet piping and air inlet piping; visually inspect piping for oil and clean interior.
- Turn compressor wheel and turbine wheel by hand; assembly should turn freely with no visible contact.
- Check the compressor wheel for cleanliness; oil on back side may indicate a failed turbocharger oil seal.
- Use a dial indicator to check the end clearance on the shaft; if end play exceeds Service Manual specifications, repair or replace.
- Inspect the bore of the turbine housing for corrosion.
- Clean the turbocharger housing with standard shop solvents and a soft bristle brush.
- Fasten the air inlet piping and exhaust outlet piping to the turbocharger housing.
