Auxiliary Engine (Generator Set) · Auxiliary Engines
This auxiliary engine employs a 4-stroke, turbocharged, and electronically direct-injected combustion cycle to achieve a power output of 74 kW at 1800 rpm. The John Deere Power Systems model 350MTB, manufactured in 2012, is designed to meet IMO Category 1 standards and EPA requirements. The engine's displacement per cylinder is 1.13 liters, and it is equipped with a robust fuel system that minimizes emissions and enhances performance. Common issues include starting failures, unstable speed, poor combustion, lubricating-oil system faults, cooling-system malfunctions, and electrical or control-interface faults. To maintain operational readiness, it is essential to keep a variety of spare parts on board, including fuel and oil filters, air-filter elements, injector spares, seals, gaskets, pump service kits, and starting-system components. For generator duties, additional governor or speed-control components, sensors, relays, and electrical interface spares should also be available. Regular service checks should include verifying starting reliability, load acceptance, speed stability, and the engine's ability to carry its assigned load, as well as inspecting fuel, oil, cooling-water, and exhaust systems for leaks and ensuring all filters and pumps are in serviceable condition.

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.
