Common failures & inspection points
Injection pump fuel rack stickiness (HFO operation) - reported in power plants using HFO 380, affecting reliable fuel delivery
Exhaust valve seat wear and carbon deposits - standard maintenance item due to high exhaust temperatures; valve seats made from Ni-Cr super alloy (ASTM A560 60C
Camshaft gear backlash and timing gear pitting/spalling - wear surfaces require monitoring during major overhauls
Bearing shell installation alignment critical - tin-aluminium-on-chrome-iron tribological pairing; 110% overload limit for 1 hour in 12
Fuel injection nozzle clogging (dirt/debris, contaminated fuel) - HFO installations use oil-cooled nozzles; MDF uses non-cooled nozzles
