What our service work and the manufacturer documentation say about keeping this model running.
Check starting reliability, load acceptance, speed stability and the engine's ability to carry its assigned electrical or mechanical load. Trend exhaust temperatures, oil pressure, cooling temperatures and abnormal vibration and compare cylinders or operating points for imbalance. Inspect fuel, oil, cooling-water and exhaust systems for leakage and verify filters, coolers, pumps and ventilation are in serviceable condition. For generator sets, verify governor response, load sharing, generator protection, emergency shutdowns and automatic-start functions where fitted. Inspect foundations, flexible mounts or couplings and the interface with the alternator or driven machine. For cylinder dimensions, rotational speed, pressures, clearances, temperatures, wear limits and setting values, refer to the manufacturer documentation for the exact figure.
Keep fuel and lubricating-oil filters, air-filter elements where fitted, injector-related spares, seals and gaskets, pump service kits and starting-system components on board. For generator duties, carry selected governor or speed-control components, sensors, relays and common electrical interface spares according to the installed control system. The final spare inventory should follow manufacturer recommendations, class requirements and the number of redundant generator or auxiliary sets available.
