When each turbocharger part is due.
Turbocharger overhaul follows the engine maker's schedule and the unit's running hours and fuel quality — not a fixed figure. This is the typical order of what wears, what we inspect and the usual action, so you can plan the parts before the survey.
| Component | Typical check | What we inspect | Typical action |
|---|---|---|---|
| Air filter–silencer | Fouling & pressure drop | Element condition, ΔP | Clean or renew element |
| Compressor wheel & diffuser | Routine | Fouling, tip erosion | Water-wash; renew if eroded |
| Nozzle ring | Routine | Vane erosion, cracking | Clean; renew on erosion |
| Turbine wheel | Routine | Deposits, cracks | Clean, NDT; renew at limit |
| Journal & thrust bearings | Maker's schedule | Clearance, oil condition | Renew at wear limit |
| Rotor assembly | Major overhaul | Runout, balance, journal wear | Re-machine, re-balance or renew |
| Labyrinth / sealing-air seals | Major overhaul | Seal wear, gas leakage | Renew seal rings |
| Complete cartridge | Major overhaul | Full strip inspection | Exchange with balanced cartridge |
