Features + Benefits

Four cycle, 4 cylinder, liquid cooled, dry turbocharged overhead valve diesel. The induction hardened, forged carbon steel crankshaft is stronger than cast iron while the cross flow head makes for more efficient breathing. Helical cut and ground, carbon steel timing gear reduce noise.

 Liquid cooled with radiator and pusher fan. Radiator shroud and guard.

Easy to service mechanical, direct injection fuel system. Spin on fuel filters with air bleed. Mechanical fuel transfer pump with manual priming plunger.

The M40C3FR is fully compliant with the US EPA Tier III emission standards. Its dry air filter silences intake noise.

Full-flow, spin-on filter with bypass. 10.5 qt (10 ltr) center well oil pan. Closed crankshaft vent system keeps oil vapor inside engine room.

The DC system uses reliable relays instead of unrepairable circuit boards. 12 volt system includes circuit breaker, starter motor and alternator regulator.

Standard flush mount S-3C control panel has hour meter, oil pressure gauge, coolant temperature gauge, DV voltmeter, stop-start switch and preheat switch. Expandable up to six panels, up to 110 feet from the set. Low oil pressure and high coolant temperature shutdowns are standard.

The Northern Lights, direct coupled, four pole, twelve lead reconnectable generator has Class “H” insulation, a pre-lubricated bearing and features a conservative heat rise rating of 95°C/50°C ambient. Engines and generators are torsionally matched for long life. Automatic Voltage Regulator (AVR) gives quick +/-1% RMS no load to full load voltage regulation.

Northern Lights Commercial Series gensets are made for the demands of the marine environment, with features including a rugged, welded steel base frame, captive vibration isolation mounts and a belt guard for operator protection.
