Background information

The 5-ton 6x6 truck, officially "Truck, 5-ton, 6x6", was a class of heavy-duty six-wheel drive trucks used by the United States Armed Forces. The basic cargo version is designed to transport a load of 5 tons (4,500 kg) over all roads and terrain in all weather conditions. Throughout three evolutionary series (M39, M809 and M939) there were component improvements, but all trucks were mechanically very similar. They were the standard heavy truck of the US military for forty years until they were replaced by the Medium Tactical Vehicle (MTV) in 1991.

M51 Dump Truck

The M51 was a dump truck used to transport sand, gravel, dirt, rubble, scrap metal and other bulk materials. It had a 10-foot-long (3.0 m), 5 cubic yard (3.8 m3) cargo box with cab protector and a tailgate that could be hinged at the top or bottom. They could be equipped with upper arches, sailcloth and troop seats, but the relatively small dimensions of the body limited their passenger or freight load.

The engine

The M39 series was originally powered by a Continental R6602 engine, a 602 cu in (9.9 L) overhead valve inline 6-cylinder gasoline engine rated at 224 hp (167 kW) at 2800 rpm. The -A1 upgrade had a Mack ENDT-673, a 673 cu in (11.0 L) turbocharged inline 6-cylinder diesel engine rated at 210 hp (160 kW) at 2100 rpm. The -A2 upgrade had a Continental LDS-465-1A, a 478 cu in (7.8 L) turbocharged inline 6-cylinder multifuel engine rated at 175 hp (130 kW) at 2100 rpm.
