An OSHKOSH Truck Maintenance Manual PDF is above this page.
OSHKOSH Trucks was founded in 1917, production sites are located in 8 states of the USA, as well as in Australia, Belgium, Canada, China, France, the Netherlands and Romania, there are joint ventures in Mexico and Brazil.
Until the 1930s, Oshkosh all-wheel drive trucks were not considered by the US military as potential army vehicles. Only in 1934 the army acquired a certain amount of 5-ton dump trucks. In 1940, the Oshkosh TR construction tractor with all driving and steering wheels was tested at the Aberdeen proving ground, adapted for towing a 155-mm M1 cannon and an 8-inch howitzer M1. The car was equipped with an adapter that allows transporting the gun in a semi-trailer condition and dispensing with a cannon-chassis. With a 14-ton gun M1, the tractor could reach speeds of up to 40 km / h, however, due to the high silhouette and vulnerability of tires, it was not adopted.
It was a scandal. It was known that it was known for its vehicles. Their volume of correspondence to the limited capabilities of the company. For example, in 1944, 75 chassis for snowplows and 76 7.5 tons class dump trucks were manufactured. Oshkosh has been equipped with a 5-ton crane boom since 1942 and has been serving the island of New Caledonia. They were used by civilian contractors in the construction of military facilities.
At the beginning of 1976, the US Army announced a competition for a truck tractor for transporting tanks, capable of replacing M123 tractors, which were not quite suitable for this role. The main condition for the participants was the creation of a car based on a commercial prototype, since it cost the military much cheaper than a car designed from scratch.
According to the results of tests in Texas, Oshkosh Corporation won with a XM911, which was a modified J-2065 model (6x6), created for the countries of the Middle East. To reduce the load on the chassis and bridges, he had an additional non-leading lifting axle. After adopting the machine received the designation M911 Commercial Heavy Equipment Transporter (commercial conveyor of heavy military equipment), or C-HET. In the autumn of 1976, a contract was signed for the supply of 774 trucks, the first were assembled in the summer of 1977. They were listed on the Oshkosh program as an F-2365 model.
The trucks operated with the M747 four-axle semi-trailer manufactured by Consolidated Diesel Electric with a payload capacity of 54.5 tons, developed in the late 1960s. According to the program of creation of the American-German transporter of tanks NET-70. The tractor had a push-pull diesel Detroit Diesel (Service Manuals page) with a capacity of 430 hp. Its gross weight was 39 tons, road trains - 87.1 tons. In total, until May 1992, 1,722 units of the M911 were built. In addition to the US Army, they were supplied to the armies of Greece, Yemen, Cyprus, Morocco, Oman, Saudi Arabia (760 units), Taiwan, and Thailand. As a rule, for export M911 came with trailers of other types and without a lifting axle. As of 2010, there were still a small number of M911s in the National Guard and reserve units of the US Army.
In addition to heavy multi-axle vehicles, Oshkosh Defense was also involved in the production of 6x6 trucks. In 1996, prototypes of the MTVR (Medium Tactical Vehicle Replacement) family of machines were created, intended to replace the standard US M809 and M939 trucks (both 6x6) in the US Marine Corps. In 1999, a contract was signed for their serial production, and the first KMP machines were received in July 2001. The family included flatbed trucks MK23, MK25, MK27, MK28, dump trucks MK29 and MK30, as well as tow truck MK36. They had a TAK-4 suspension and were equipped with 425 hp Caterpillar (Service Manuals PDF page) diesel engines.
The total mass of cars in different versions was 26.2–27.7 tons, and off-road capacity was 6.4 tons. In 2005, the family was supplemented with a MK31 tractor unit with all steering wheels; a batch of armored cabs and bodies for the transport of personal composition. In addition to the Marine Corps, a small number of MTVRs (including the MK31 tractors) were received by the Seabees Marine Construction Battalions. In May 2008, the 10,000th copy of MTVR was built. In addition to the serial variants, a prototype of a 15-ton truck with the formula 8x8 and a short base type 4x4 were created. However, the most unusual version of MTVR was the TerraMax truck robots, developed in collaboration with Teledyne Scientific.
In 2004–2007 on the runs of cars without drivers, organized by the Agency of Advanced Defense Research Projects (DARPA), TerraMaxa independently passed routes with a length of up to 280 km. Work on the creation of autonomous cars continues in our days. MTVR trucks are in the armies of Greece and the UK. The latter has a fleet of 357 truck tractors with semi-trailers.
