Inspector Detail ✓ verified

Designation decoded

8 steht für 8 Zylinder, G für Green Ultra-Long-Stroke, 60 für 600 mm Bohrung, ME-B für elektronisch gesteuerte Kraftstoffeinspritzung mit nockenwellengesteuertem Auslassventil, 9.5 für Mark 9.5.

Background

Die G60ME-B9.5 mit 8 Zylindern bietet hohe Leistung in der 60er-Bohrungsklasse bei maximalem Wirkungsgrad. S/B 4.65 bei 600 mm Bohrung. Einsatz in Panamax-Bulkern und mittelgroßen Containerschiffen. 8 Zylinder für bestes Schwingungsverhalten.

Inspector checklist

Laufzeug & Tribologie
  • Zylinderlaufbuchsen: S/B 4.65 — extrem hohe Seitenkräfte, Druckseiten-Verschleiß
  • Kolbenringe: Maximaler Seitendruck — Ring-Stabilität
  • Alpha-Lubricator: Kalibrierung und Quill-Durchfluss bei 600 mm
Kreuzkopf & Stopfbuchse
  • Kreuzkopflager: Temperatur über 8 Zylinder
  • Stopfbuchse: 2790 mm Hub — Drainage
  • Kolbenstange: Rundlauf
Elektronische Steuerung
  • ME-B: Sensoren, EICU
  • Nockenwelle: Kettenlängung
  • Software
Spülluft & Abgassystem
  • Spülluftkasten: Bei 600 mm zugänglich — bei G-Typ Öleintrag-Risiko
  • Turbolader: 2 TC bei 8×60
  • Abgastemperatur über 8 Zylinder

Common Failure Modes

  • Extremer Liner-Verschleiß

    Symptoms: Hohe Wear-Rate, einseitig

    Causes: S/B 4.65, Quill-Verstopfung

    Preventive: Alpha-Lubricator kalibrieren, Quills testen

  • Stopfbuchsen-Verschleiß

    Symptoms: Steigende Drainage

    Causes: 2790 mm Hub

    Preventive: Drainage-Trend, kürzere Intervalle

  • Elektronik-Fehler

    Symptoms: Zylinderabschaltung

    Causes: Sensor

    Preventive: Kalibrierung

Expert tips

  • 8×G60ME-B9.5: Gutes Schwingungsverhalten bei hoher Leistung — Spülluftkasten bei 600 mm begehbar, bei G-Typ unbedingt regelmäßig nutzen
  • Bei 2 Turboladern und Slow Steaming: TC-Cut-Out-Prozedur bei ME-B prüfen
  • Quill-Kontrolle bei 600 mm und G-Typ: Jede einzelne Quill auf Durchfluss testen

Makers and authorised dealers rarely quote marine equipment without the vessel. With these details we can check availability and prices faster; without them we may have to ask first, which can cost a few days. If you cannot share the vessel, a photo of the equipment’s rating plate does the same job — attach it below or send it as a reply to our confirmation e-mail.
