Auxiliary Engine (Generator Set) · Auxiliary Engines
This is a marine diesel engine designed for auxiliary power applications. The Deere 650MAE is a powerful engine with a rated output of 367 kW. This engine features a six-cylinder, 4-stroke compression ignition design with a turbocharged, direct injection fuel system. It meets EPA emission standards under the LJDXN13.5159 engine family designation. The 650MAE is categorized as an IMO Category 1 engine and was designed for operation within a constant speed auxiliary cycle. Common potential issues with this engine include fuel system contamination, lubrication system problems, cooling system inefficiencies, and turbocharger malfunctions. To ensure reliable performance, it's important to regularly check engine parameters like oil pressure, coolant temperature, and exhaust temperatures. Routine inspections of filters, coolers, fuel systems, and safety devices are also crucial. When ordering spare parts, always refer to the manufacturer's documentation and specify the engine's serial number and installed emissions package. A surveyor typically looks for evidence of well-maintained machinery spaces, leak control, and properly functioning safety systems.

What our service work and the manufacturer documentation say about keeping this model running.
Review operating trends for lubricating-oil pressure, coolant temperature, exhaust temperatures, load balance, crankcase condition and abnormal vibration or noise. Inspect filters, coolers, fuel equipment, valve gear, turbocharging equipment, mounts, flexible connections and safety shutdown devices in accordance with the installed configuration. Check for fuel, oil, coolant and exhaust leakage and verify that protective alarms and shutdowns are functional. A surveyor will normally look for evidence of disciplined maintenance, clean machinery spaces, leak control, intact guards and reliable safety functions. Use the engine serial number and manufacturer documentation for all exact wear limits, adjustment values and overhaul criteria.
Useful onboard spares typically include fuel-system service items, lubricating-oil and fuel filters, cooling-system seals, belts where fitted, valve-train consumables, injector-related service parts, sensors and common gaskets or O-rings. Critical spares should be selected against the exact engine serial number, installed emissions package and vessel redundancy; refer to the manufacturer parts documentation before ordering.
