The Scania-Vabis L10/L40/L51 was a series of trucks produced by Swedish automaker Scania-Vabis between 1944 and 1959.

A truck or lorry is a motor vehicle designed to transport cargo. Trucks vary greatly in size, power, and configuration; smaller varieties may be mechanically similar to some automobiles. Commercial trucks can be very large and powerful, and may be configured to mount specialized equipment, such as in the case of fire trucks, concrete mixers, and suction excavators.

Sweden, officially the Kingdom of Sweden, is a Scandinavian Nordic country in Northern Europe. It borders Norway to the west and north and Finland to the east, and is connected to Denmark in the southwest by a bridge-tunnel across the Öresund, a strait at the Swedish-Danish border. At 450,295 square kilometres (173,860 sq mi), Sweden is the largest country in Northern Europe, the third-largest country in the European Union and the fifth largest country in Europe by area. Sweden has a total population of 10.2 million of which 2.4 million has a foreign background. It has a low population density of 22 inhabitants per square kilometre (57/sq mi). The highest concentration is in the southern half of the country.

During the Second World War Scania-Vabis’ entire production went to the Swedish Armed Forces and other public institutions. The company designed a new generation of trucks for post war times, when the pent-up demand for new trucks was expected to boom. The first post-war model, L10, was introduced in 1944.^[2] It was the first Scania-Vabis truck with left hand drive. The L10 Series had a four-cylinder variant of the module engine Scania-Vabis had introduced in the late 1930s, which was also built in the six- and eight cylinder versions, as petrol or diesel engine. The diesel engine in the L10 series was a pre-chamber engine. The truck could also be delivered with four-wheel drive, a version known as the F10. It had a war time chassis and military trucks were also sold with petrol engine.

The Swedish Armed Forces is the government agency that forms the military forces of Sweden, and which is tasked with defence of the country, as well as promoting Sweden's wider interests, supporting international peacekeeping efforts, and providing humanitarian aid.

A petrol engine is an internal combustion engine with spark-ignition, designed to run on petrol (gasoline) and similar volatile fuels.

The diesel engine, named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel, which is injected into the combustion chamber, is caused by the elevated temperature of the air in the cylinder due to the mechanical compression. Diesel engines work by compressing only the air. This increases the air temperature inside the cylinder to such a high degree that atomised diesel fuel injected into the combustion chamber ignites spontaneously. This contrasts with spark-ignition engines such as a petrol engine or gas engine, which use a spark plug to ignite an air-fuel mixture. In diesel engines, glow plugs may be used to aid starting in cold weather, or when the engine uses a lower compression-ratio, or both. The original diesel engine operates on the "constant pressure" cycle of gradual combustion and produces no audible knock.

Before the war, Scania-Vabis purchased many components from Germany and Great Britain, but these were now largely replaced by Swedish-made components. Unfortunately, production was in several cases started without adequate testing and those first postwar trucks suffered quality problems that cost Scania-Vabis both money and reputation to repair.^[3]

Germany, officially the Federal Republic of Germany, is a country in Central and Western Europe, lying between the Baltic and North Seas to the north, and the Alps to the south. It borders Denmark to the north, Poland and the Czech Republic to the east, Austria and Switzerland to the south, France to the southwest, and Luxembourg, Belgium and the Netherlands to the west.

Great Britain is an island in the North Atlantic Ocean off the northwest coast of continental Europe. With an area of 209,331 km² (80,823 sq mi), it is the largest of the British Isles, the largest European island, and the ninth-largest island in the world. In 2011, Great Britain had a population of about 61 million people, making it the world's third-most populous island after Java in Indonesia and Honshu in Japan. The island of Ireland is situated to the west of Great Britain, and together these islands, along with over 1,000 smaller surrounding islands, form the British Isles archipelago.

Scania-Vabis L40

At the end of 1949, Scania-Vabis introduced a direct injected diesel development of their module engine. It had been designed in collaboration with British truck manufacturer Leyland Motors.^[3] With the new engine, the four-cylinder truck got its name changed to L40. Otherwise the truck was mostly unchanged. In early 1950 there were also a small number of the four-wheel drive F40 built, before that model disappeared because of low market demand. In 1951 the old fashioned non-synchro four-speed gear box was replaced by a synchronized five-speed transmission.

Leyland Motors Limited was a British vehicle manufacturer of lorries, buses and trolleybuses. The company diversified into car manufacturing with its acquisitions of Triumph and Rover in 1960 and 1967, respectively. It gave its name to the British Leyland Motor Corporation, formed when it merged with British Motor Holdings in 1968, to become British Leyland after being nationalised. British Leyland later changed its name to simply BL, then in 1986 to Rover Group.

A non-synchronous transmission is a form of transmission based on gears that do not use synchronizing mechanisms. They are found primarily in various types of agricultural and commercial vehicles. Because the gear boxes are engineered without "cone and collar" synchronizing technology, the non-synchronous transmission type requires an understanding of gear range, torque, engine power, range selector, multi-functional clutch, and shifter functions. Engineered to pull tremendous loads, often equal to or exceeding 40 tons, some vehicles may also use a combination of transmissions for different mechanisms. An example would be a power take-off.

Scania-Vabis L51 Drabant

In the spring of 1953 the final development of Scania-Vabis’ module engines were introduced, with larger displacement. The four-cylinder truck was now called L51 Drabant, with a payload capacity of 5.5 to 6 tonnes. It was also the first Scania-Vabis truck with a proper name.

The tonne, commonly referred to as the metric ton in the United States, is a non-SI metric unit of mass equal to 1,000 kilograms; or one megagram (Mg); it is equivalent to approximately 2,204.6 pounds, 1.102 short tons (US) or 0.984 long tons (UK). Although not part of the SI, the tonne is accepted for use with SI units and prefixes by the International Committee for Weights and Measures.

The automotive industry in Sweden is mainly associated with passenger car manufacturers Volvo Cars and Saab Automobile but Sweden is also home of two of the largest truck manufacturers in the world: Volvo AB and Scania AB. The automotive industry is heavily dependent on export as some 85 percent of the passenger cars and 95 percent of the heavy vehicles are sold outside of Sweden. The automotive industry and its sub-contractors is a major part of Swedish industry. In 2011 around 110,000 people were employed and the export income of 150 billion SEK accounted for 12 per cent of Sweden’s export income. During 2009 128,738 passenger cars and 27,698 heavy vehicles were built in Sweden.
