  • Fuel-Booster: Druck, Filter
  • Vorwärmer: HFO/VLSFO
  • ME Timing: EICU 7-Zyl 9.6
Laufzeug & Tribologie
  • Ratio 4.65: Guide-Shoes alle 7 — Hauptpriorität
  • Laufbuchsen: Verschleiß, Cold Corrosion
  • Zylinderöl: Alpha Lubricator Mark 9.6
Steuerung & Hydraulik
  • 7 HCUs: 200-300 bar gleichmäßig
  • EICU 9.6: Diagnostik
  • Hydrauliköl: Reinheit
Abgassystem
  • TC (2x): Reinigung, Lager
  • Abgaskessel
  • Spülluft-Receiver: Bei 7 Zyl längerer Receiver — Drainage beidseitig
Dichtungen

    Preventive: Spiel alle 8000 Bh alle 7

  • Cat-Fine-Schäden

    Symptoms: Liner-Verschleiß

    Causes: Cat-Fines

    Preventive: Separator; Fuel-Analyse

  • Zylinderbalance 7 Zyl

    Symptoms: Temperatur-Fächer

    Causes: Ungleicher Injektor-Verschleiß

    Preventive: Satzweiser Tausch

Expert tips

  • 7G60 Mark 9.6: Bestseller mit umfangreicher Flottenerfahrung. EICU-Diagnostik bietet PMI und CoCoS-Daten — für proaktive Wartung nutzen.
  • 7 Zylinder bei Ratio 4.65: Guide-Shoes sind der Hauptinspektionspunkt neben Cat-Fine-Management.
  • Spülluft-Receiver bei 7 Zylindern: Länger als bei 6 Zyl — Kondensat sammelt sich an den Enden.

Request a quote for this model.

Free of charge — we forward your request to qualified suppliers for MAN Energy Solutions equipment from our network of over 114,000 maritime companies.

Makers and authorised dealers rarely quote marine equipment without the vessel. With these details we usually come back with prices; without them we have to ask first, which costs a few days. If you cannot share the vessel, a photo of the equipment’s rating plate does the same job — send it as a reply to our confirmation e-mail.

Your contact details are not published. No account required.
