GAZ-51: technical specifications. GAZ-51: tuning

GAZ-51 is a truck of the Soviet period, popular in the 50s of the last century. A load capacity of 2.5 tons allowed the use of the machine in almost all sectors of the national economy of the USSR. The model was a fairly reliable flatbed truck. Over 30 years of continuous production, 3,480 thousand vehicles of various modifications have been rolled off the assembly line.

History of creation

In 1937, a project was launched at the Gorky Molotov Automobile Plant to create a new middle-class truck. The concept of the car was defined quite clearly: for the needs of the national economy, a universal, reliable and unpretentious carrier was required. This car was the GAZ-51, the technical characteristics of which from the very beginning were very good.

Tests

In the summer of 1938, they launched the production of basic components and assemblies, in January 39th the first prototypes were assembled, and after another year and a half, the new machine passed the tests.In the summer of 1940, the GAZ-51 was exhibited at the Exhibition of Economic Achievements in Moscow as the best achievement of Soviet engineering.

Prewar period

In the spring of 1941, the technical documentation was transferred to the assembly shop of the plant to start the machine into mass production. But the war began, and the release of a new car had to be suspended. Developments in aggregates were useful for other vehicles, including military ones. The engine and gearbox GAZ-51, the propeller shaft with cross-pieces on needle bearings, the clutch with the release bearing and other components were used in the manufacture of military equipment.

Start of release

After the end of the war at the Gorky Plant, they continued preparations for the mass production of GAZ-51, and by the end of 1945 an installation batch of 20 cars was produced. The new car immediately proved itself as a reliable and inexpensive truck in operation. Gearbox GAZ-51 has been improved, and the transmission of the car worked flawlessly. The production continued, and in 1946, 3,136 cars entered the roads of the country.

Speed ​​characteristics

The model was very simple. It was the first truly successful product in the USSR that did not require any improvements. Characteristics of the GAZ-51 seemed flawless.The car was fast, its cruising speed was about 75 km / h. The car steadily held the road, while differing in ease of operation. Sufficiently soft suspension combined with effective hydraulic shock absorbers made it possible to reach speeds of over forty kilometers per hour on country roads, which was a tangible advantage in comparison with other vehicles.

Stalin Prize

The performance of the GAZ-51 was higher than that of the popular "three-ton" ZIS-5, while the Gorky car consumed 30% less fuel. With all the advantages, both speed and economic, the machine was recognized as the most suitable for the needs of agriculture. Since the end of 1946, almost all cars directly off the assembly line were sent to collective and state farms. And in 1947 a group of car makers, together with the chief designer of the Gorky plant A. Lipgart, was awarded the Stalin Prize.

Production expansion

Gosplan USSR monthly submitted applications for the release of GAZ-51 in an amount far exceeding the production capacity. Thus, the question arose about the expansion of the assembly areas.In 1948, the production of popular cars was mastered at the Odessa Automobile Assembly Plant, and in 1950, the conveyor was launched in Irkutsk, where production continued from 1950 to 1952, then the production of trucks was turned off for a number of reasons. In Odessa, cars were produced for 27 years. The last car that came off the assembly line on April 2, 1975, was sent to the factory museum.

Engine

The power plant machine is fully consistent with the tasks that were set in front of the truck. The optimal cylinder volume allowed us to develop sufficient power to move in any mode. Engine GAZ-51 had the following characteristics:

  • type - gasoline;
  • the number of cycles - 4;
  • cylinder volume - 3 485 cube / cm;
  • power - 70 horsepower at 2750 rpm;
  • torque - 200 Nm at 1500 rpm;
  • cylinder arrangement - inline;
  • number of cylinders - 6;
  • the number of valves - 12;
  • cylinder diameter - 82 mm;
  • compression ratio - 6.2;
  • cooling system - circulating fluid, closed loop;
  • power system - carburetor.

Enhancements

The motor is the successor to the powerplant GAZ-11, which was once created on the basis of Chrysler's lower-valve engine under a license from 1937.The piston group was constantly improved, the liners were installed from special wear-resistant cast iron, compression piston rings were chrome-plated, new bimetallic (steel-Babbit) liners for the crankshaft main and connecting rod necks were developed. As a result of the application of technical innovations, the engine resource has increased significantly.

Modernization

In the course of the modernization, an aluminum block head and plug-in seats were used for the valves. The car gradually absorbed all the advanced technologies, its design was gradually improving. In 1954, the cab of the car became all-metal, at the same time the heater was installed. The new cabin has become an incentive for changing the shape of the front end, the lining has acquired a more modern look, the wings with headlights organically fit into the overall style. Behind the grille, special vertical louvers were installed that prevented excessive engine cooling in winter.

Export

In 1949, a modification of the GAZ-51U was developed, which was intended to be sent abroad to countries with a temperate climate. The machine was exported for six years, from 1949 to 1955, in small batches.Then the design office of the Gorky Automobile Plant developed the GAZ-51Y model adapted for use in tropical climates. This modification was produced for almost twenty years, from 1956 to 1975. The trucks were sent to Africa and Asia, where they were used on construction sites or used as a regular vehicle for the transport of goods and livestock.

A model of increased payload - GAZ-51V was also supplied for export. The car body could hold 3.5 tons. Production lasted from 1957 to 1975. The car was equipped with an engine with 78 horsepower, the rear axle GAZ-51 was borrowed from the all-wheel drive all-terrain vehicle GAZ-63. Larger tires were used - 8.25x20.

Another export modification - GAZ-51DU. It was a car for the regions with a temperate climate, made on the basis of a dump chassis.

GAZ-51DYu was exported to GAZ-93AT dumping base to countries with a tropical climate.

Truck tractors were also exported: GAZ-51PU was intended for countries with moderate climatic conditions, GAZ-51PY - for hot regions.

Tuning

Some cars of the past, the release of which stopped many years ago, sometimes get a second life. Restoration of cars 50-60-ies engaged in enthusiasts and collectors. They find preserved rarities in landfills or in abandoned garages, transport them to their workshops and there already begins the long and painstaking process of reviving the car.

Simultaneously with the restoration often updated exterior. This creative process is called tuning. As a result of alterations, the car can drastically change its appearance.

GAZ-51, the tuning of which was made possible thanks to the use of the latest technologies and the latest technical means, is one of the cars of the middle of the last century, which has a good potential for reincarnation.

At the first stage, it is necessary to compile a list of all the changes that tuning masters intend to make to the exterior of the car. The accuracy of the drawings is important. GAZ-51, the tuning of which may be complicated by the dimensions of the car, should be carefully measured and two sets of technical documentation made — original dimensions and change parameters.Then you can get to work. For a full-fledged tuning, you will need equipment in the repair shop assortment: gas welding, Bulgarian, a drilling machine, a set of bench tools, painting equipment.

GAZ-51, the technical characteristics of which are considered ideally suited for tuning conditions, can be a good object for creativity. A tuned car can become a participant of the exhibition of rare automotive vehicles, as well as fairs and sales of old vehicles. If the rarity is in good technical condition, he will be able to take part in the rally or even in competitions.
