Common issues
- Compressor wheel fouling due to poor air filtration
- Turbine blade erosion from high-temperature exhaust gases
- Bearing wear and vibration caused by misalignment or imbalance
- Oil leakage from turbocharger bearings or seals
- Compressor surge and stall from incorrect turbocharger sizing or operation
- Turbine casing cracks from thermal stress or mechanical overload
- Rotor imbalance due to worn or damaged compressor or turbine blades
Inspection checklist
- Visual inspection of compressor and turbine blades for damage or wear
- Check of bearing condition and vibration levels
- Inspection of oil system for leaks or contamination
- Verification of turbocharger alignment and mounting
- Check of compressor inlet and outlet pressures
- Inspection of turbine casing and exhaust gas system for signs of overheating or damage
- Verification of control system operation and settings
- Check of turbocharger performance and efficiency
