Common failures & inspection points
WECS-9520 Steuerungssystem-Ausfälle (dokumentierte Mängel in Servoöl-Lecks, Kraftstoff-Lecks, Drossel-Einspritzventile)
Cooling water leakage in cylinders and exhaust valve actuator deficiencies; inspection routine for high-pressure SCR system required
Bearing and piston cooling oil temperature monitoring critical; condensate flow at water separator too high (scavenging cooling system fouling)
Thermal stress cracks in cylinder head (valve bridge): cyclic thermal load at load changes 70-80 RPM; exhaust valve seating surface wear requires sc
Turbocharger oil leakage and leaks; scavenge air cooler fouling (air side: pressure drop, temperature rise; water side scaling)
