Biography of the M809 Series of Trucks

The M809 5-ton, 6x6 trucks were manufactured between the years 1969 and 1982, by Kaiser Jeep , who later became AM General. By the end of production there have been approximately 92,000 M809s designed. In the 1960s, the U.S. Army wanted to replace the standard multi-fuel engines with diesel engines. The M809 series is an upgraded version of the 5-ton M39 series, but they are still mechanically similar in design. The M809 series and its variants are known as the G908 series by the U.S. Army Ordnance Corps Supply Catalog. The primary function of the M809 truck is to transport troops, cargo and materials over any terrain, up to 5-tons (10,000lbs (4,500 kg)) and in most cases doubling the load size.

The M809 series has three wheelbases short, standard long and extra-long. At 14ft 11in (4.55m) the M809 is considered the “standard long wheeled.” The M810 is the “short wheeled” at 13ft 11in (4.24m). The M811 and M812 are the “extra-long wheeled” at 17ft 11in (5.46m). The M809 series has a ladder frame with three axles. The front axle is on semi-elliptical leaf springs and the rear tandem on quarter elliptical leaf springs. The M809 has an extended hood, frame, and fenders compared to the M39 , to make room for the only engine used in the M809s , which is a 240hp Cummins NH250, naturally aspirated diesel engine. The transmission is a Dana-Spicer manual, 5-speed, with a Rockwell-Standard 2-speed transfer case that engages the front axle. The brakes are air over hydraulic with drum brakes on all the wheels. Variants requiring a trailer, use air brake connections that are separate from the service brakes. The M809s have a redesigned grille and an air cleaner on the left front fender. They also have a rear pintle hitch which can tow 15,000lb (6,800kg) trailers and a front mounted 20,000lb (9,100kg) capacity winch.

Since this series does not have any engine or transmission upgrades, the designations for the variants can be identified by wheelbase lengths and operation of the vehicle. The M813 & M814 are cargo trucks. The M815 is a bolster truck. The M816 and M819 are wrecker/recovery trucks. The M817 is a dump truck. The M818 is a tractor. The M820 has an expansible van body and the M821 is a bridge transporter.
