Common failures & inspection points
Inspect fuel valve nozzle spray pattern during top-overhaul; monitor differential pressure across fuel filter; verify fuel heating system temperature compliance
Measure piston crown surface condition using borescope; check for micro-cracks in top land; examine combustion bowl geometry; compare cylinder-to-cylinder pressure readings
Perform liner diameter measurement service at each overhaul; document wear rate trending; inspect piston rings for abnormal wear patterns; check air inlet filter condition
Monitor turbocharger bearing temperatures during mode transitions (gas-to-diesel); inspect turbocharger for cavitation pitting on impeller; verify surge line compliance in operational envelope
Perform fuel gas system pressure step-response test during commissioning; verify regulator response time <500ms per specification; conduct annual gas line tightness test with ultrasonic detection
