| General visual inspection | 500-1000 running hours |
|---|---|
| Compressor water washing | 250-500 running hours (as required by performance drop) |
| Turbine dry cleaning (granulate) | 1000-2000 running hours (as required) |
| Bearing inspection and replacement (plain bearings) | 8,000-12,000 running hours |
| Rotor inspection, cleaning, and balancing | 12,000-16,000 running hours |
| Major overhaul (including full disassembly, inspection, and component replacement as needed) | 16,000-24,000 running hours |
Typical intervals for this design class, not the manufacturer’s figures for your model. The manufacturer’s manual is binding.
| Radial bearing clearance (new) | 0.25 - 0.35 mm |
|---|---|
| Radial bearing clearance (max wear limit) | 0.60 - 0.70 mm |
| Axial bearing clearance (new) | 0.10 - 0.18 mm |
| Axial bearing clearance (max wear limit) | 0.30 - 0.35 mm |
| Turbine blade erosion/pitting | Max 10-15% material loss or specific depth as per manual (e.g., 1.5mm deep pitting) |
| Nozzle ring distortion/gap deviation | Max 0.5 mm deviation from flatness or specified gap |
| Rotor imbalance (vibration amplitude at bearing housing) | Max 0.05 mm peak-to-peak |
Ranges are typical for this design class. Always confirm against the manufacturer documentation for your serial number.
Class surveyors typically verify the turbocharger's maintenance history, including running hours since last major overhaul, bearing replacements, and cleaning records. They will conduct a thorough visual inspection for external leaks, damage, and secure mounting. Key checks include rotor axial and radial play measurements (if accessible), condition of air filters, and verification of safety devices like overspeed trip mechanisms. Performance parameters (boost pressure, exhaust temperatures) are often reviewed against design values. Any excessive vibration or unusual noises during operation will prompt further investigation. The surveyor may request opening for internal inspection if service records are incomplete or issues are suspected.
Estimated lifetime: 100,000 - 150,000 hours with proper maintenance, adherence to service intervals, and timely component replacement.
