GAZ-3307 - Soviet medium duty truck fourth generation trucks Gorky car factory. This model in 1989 replaced the most massive trucks in the history of the enterprise - GAZ-53 and GAZ-52, and by 1993 had completely replaced them from the factory conveyor. GAZ-3307, the last GAZ carburetor truck, became the ancestor of a whole family of gasoline and diesel, rear- and all-wheel drive trucks, outwardly very similar friend on a friend.

GAZ-3307 is a two-axle truck with rear axle drive. The rear axle of the machine is equipped with a hypoid final drive. Modifications:

GAZ-ZZO7- basic, universal chassis for installation various bodies and special add-ons;
GAZ-ZZO701– special execution for a cold climate;
GAZ-ZZO706- export option for countries with a temperate climate;
GAZ-330707- export option for countries with a tropical climate;
GAZ-ZZO73- cargo-passenger version;

GAZ-33073. Cargo-passenger means with an awning and benches in the back

GAZ-ZZO75 And GAZ-33076- LPG versions, operating respectively on liquefied petroleum gas (propane-butane) and compressed natural gas;
GAZ-ZZO72– special chassis for dump trucks;
GAZ-ZZO74– special chassis for buses.

Work on the creation of a machine that was supposed to replace / began in the late 70s. The first prototypes, under the factory index GAZ-4301, were built in 1979. Second series experimental machines was completed in 1981. The car received a more spacious and modern, at that time a double cabin, equipped with more efficient system ventilation and heating.

There is an opinion that when it was created, GAZ design engineers focused on the cab of the West German Magirus-Deutz trucks, a large batch of which was purchased by the Soviet Union for work at the BAM and other shock construction sites in Siberia and the Far East.

Magirus-Deutz.

In parallel with the carburetor, the creation and diesel version new Gorky truck. In December 1986, the company completed testing GAZ-ZZO7, and in 1989 this model was launched in mass production. The main engine of the GAZ-3307 was the ZMZ-5231.10 engine.

The era of carbureted trucks was a thing of the past, and they were gradually replaced by diesel "brothers" - first with a 6-cylinder diesel air cooling GAZ-542 with a capacity of 125 hp, produced under license from the German company Deutz, and then with a turbodiesel from the Minsk Motor Plant D-245.7.

Experienced GAZ-4301 is a prototype of the future GAZ-3307.

In 1996-1997, GAZ-ZZO7 trucks were not produced, then they returned to the mass production of the plant, albeit in rather modest volumes. Serial production of a model with ZMZ gasoline engines was discontinued in 2009, but their small-scale production continued. These are certified state structures special versions. In the free market of cargo transportation, GAZ-3307, of course, has not been competitive for a long time and has practically no chance of finding buyers.

Since the end of 2016, these few new GAZ-ZZO7 have been equipped with upgraded injection gasoline engines ZMZ-524400 of the V8 type with a capacity of 137 hp. with hydraulic valve compensators in the timing, with port injection fuel (gasoline AI-92 and AI-95) and catalytic converter(Euro-4).

The GAZ-3307 car is a model of a truck vehicle, which is widely used in Soviet Union and Russia. Note that this medium-duty truck belongs to the 4th generation of vehicles produced at the Gorky plant. The first model appeared a little less than thirty years ago - in 1989. In subsequent years, vehicles were designed and mass-produced, which underwent a modernization process. The manufacturer changed the technical characteristics of the GAZ 3307, improved the carrying capacity, and so on. Note that the vehicles of this model are designed for operation on all types of solid pavement. Starting from the 99th year, GAZ 3307 53 is produced in the form of a two-ton truck, which differs a high degree patency. This allowed it to be used with difficult conditions on the road not only in our country, but also in foreign countries.

GAZ 33073 is a car equipped with powerful engine and designed for the implementation of the transportation process, as well as the rapid unloading of all types of bulk cargo. In particular, the vehicle is most comfortable to use in the field Agriculture, since with its help it is possible to overcome dirt roads, transport grain, vegetables and fruits. At a time when collective farms worked, this model used in almost every one of them. At the same time, to date, the trend in this matter has not changed in any way. The car is operated by farmers. It is impossible not to say about the fact that GAZ 33072 has found wide distribution in the process of transporting various kinds of building materials. Here we are talking about crushed stone, sand, expanded clay materials and so on.

Specifications GAZ 3307

talking about technical characteristics GAZ 3307 First of all, I would like to talk about steering. It should be noted that this car model has a mechanical steering. Such technical features, as there is no power steering here. talking about steering column, it should be noted that it is attached by means of bolts to a special bracket. It is on it that the brake-type pedals and clutch are located. Despite the lack of power steering, this model handles relatively well when compared to other vehicle models.

Separately, talk about brake system. Three brake systems were installed in this truck model. The main one is presented in the form of a hydraulic vacuum booster and a cylinder with a valve. Piston movement process brake cylinders performed by pressing the brake pedals. As a result, a strong overpressure occurs in the structure and this contributes to the process of actuation of the brake system. Also presented here spare system braking. If we talk about holding a car when it is parked "at an angle", then a parking system is used. This type system is necessary in order to keep the car in the process of parking or slope. mechanical drive is a cable and it is turned on with a lever located in the cabin.

It cannot be said about electrician, in this car model. IN this case talking about single wire electrical system having a rectifier and a transistor voltage regulator. In addition, here is the battery. The capacity of a standard battery is 75 amps/hour. Electricity is necessary to be able to turn on the light, lights, heater, starter, and glass cleaners.

The vehicle belongs to medium-tonnage, since the carrying capacity of the GAZ 3307 onboard is 4.5 tons. This indicator may vary slightly, depending on the modification of the car.

Vehicle engine specifications

Separately, it is necessary to talk about the technical characteristics of the GAZ 3307 engine. Most often, a gasoline eight-cylinder engine is used in vehicles of this type. The volume of the GAZ 3307 engine is 4 liters. Speaking about the power of the GAZ 3307 engine, it is 92 kW.

Initially, the manufacturer recommended using gasoline fuel brands AI-80 and AI-76. At the same time, new models are designed to use more quality fuel. It is worth saying that if it is operated new truck, then to use gasoline with a higher octane rating you must first perform the adjustment procedure. This model has a liquid-type engine cooling system, and the gases that have been exhausted pass through the cleaning process through recirculation devices. In addition, there is a valve-type mechanism, which is located at the top of the motor. Lubrication can enter the engine in two ways - it is sprayed or it enters under high pressure.

Truck body

The process of overturning a metal body is carried out using hydraulic system. In turn, the presence of an electro-pneumatic mechanism allows you to control this process. The body platform is equipped with sides that can be folded down. This is very convenient if unloading and loading operations are regularly performed on the car. Depending on the modification, the unloading process is carried out different ways. Here we are talking about the possibility of tilting the platform back, by tilting. In the second option, it is supposed to unload in several directions.

Speaking about the dimensions of the GAZ 3307 body, they are 6550x2380x2350 millimeters. The clearance height is 265 millimeters. As you can see, the dimensions of the GAZ 3307 are similar to other models that are similar in terms of purpose.

Many people who are thinking about the need to purchase this truck, also interested in the fuel consumption of the GAZ 3307. The technical characteristics in this matter also do not differ much from most similar cars. Gasoline consumption for a hundred kilometers of the road may depend on different parameters. First of all, this is about:

Road condition.
Movement speed.
The technical condition of the vehicle.
Vehicle load.

On average, it is noted that the consumption of gasoline per 100 kilometers of road is about 30 liters. This figure may be slightly higher or lower. Note that if the car is operated for transportation over short distances, then it can be installed gas equipment. This allows you to save on fuel.

In general, this truck model has more advantages than disadvantages. Among the main advantages of operating onboard GAS 3307 allocate unpretentiousness to conditions environment, wear resistance of parts, the ability to perform repairs according to affordable price. In addition, the car has not the most poor performance load capacity, for vehicles in its class. The only drawback that drivers highlight is the not very large cabin. Moreover, if the car travels for short distances, then this will not be a problem. Reviews about the 3307 model from the Gorky Automobile Plant will be positive.

The cost of a truck and similar models

People who are interested in this model of vehicle are interested in the question of cost. It should be noted that in this case it is very difficult to provide an answer, since the price depends on the modification of the truck, its characteristics, technical condition, year of issue, the need for repair work and so on.

In general, if you study all the ads for the sale of used vehicles, we can conclude that the cost of this model varies from 40 to 250 thousand rubles. Typically, the lower bound pricing policy characterized by those models that are in poor condition. Speaking of models, the price of which reaches 250 thousand Russian rubles, they were released relatively recently and, as a result, do not have any operational problems.

On domestic market many models of cargo vehicles are presented, aimed at solving similar problems. In this case, we are talking about trucks- GAZ-33-12, as well as ZIL 4331. At the same time, their cost is greater. In terms of technical parameters, the vehicles are almost on the same level. Also similar to this car is the lawn "Next".

Conclusion

The GAZ-3307 car, over the past three decades, has become widespread in our country, as well as in neighboring countries. The model from the Gorky Automobile Plant is reliable and functional. It is aimed at solving various problems that are associated with the transportation of goods over short distances. For this reason, the model has found distribution in different areas activities.

It is worth saying that this GAZ truck model is reliable. At the same time, if the car is not serviced or cared for, this will contribute to the wear of components. Timely passing technical inspection vehicle, there should not be any problems with it and, accordingly, it will last for many years.

GAZ-3307 was produced at the Gorky plant. The first model appeared a little less than thirty years ago - in 1989.

The GAZ-3307 dump truck belongs to the fourth family of medium-duty vehicles Gorky plant. Onboard GAZ-3307 has been produced since 1989. In 1994 it was replaced by GAZ-3309 with diesel engine. The car became the first representative fourth generation trucks manufacturer.

Dump truck GAZ-3307: history

The leadership of the Gorky plant realized the need for changes in the design of equipment in the 80s. Since that time, the development of cars began, mainly unified with third-generation models, but more productive and powerful. Thanks to the actual transfer of the main components from one generation of equipment to another, it was possible to reduce the cost of repairs, spare parts and interservice maintenance machines.

Responding to the requirements of the time, GAZ-3307 offered the user a spacious double cabin with ventilation and heating. At the end of 1989, mass production of the 3307 model was launched with factory ZMZ engine and wheel formula 4x2. The machine had a carrying capacity of 4.5 tons and was designed to drive on paved roads.

Dump truck GAZ-3307: specifications

According to experts and users, GAZ-3307 cars have many drawbacks. Suspension design makes movement along bad roads practically impossible. The crankshaft oil seal is prone to leakage, and the motor cannot boast of efficiency. Nevertheless, for its time, the GAZ-3307 became an acceptable development, which allowed the technique to hold its position for several years. Later, in 2008, the car was again released from the assembly line.

2008 engine

Cars of the new line of the fourth generation GAZ received carburetor engines ZMZ-5321.10. Eight-cylinder, four-stroke petrol engine V-arrangement cylinders, which allowed to achieve high output power. The unit was cooled by a liquid system and equipped with additional system exhaust gas recirculation. The aluminum block and cylinder head were complemented by an OHV valve train. The engine belonged to the third ecological class.

At a maximum crankshaft speed of 3200-3400 rpm, the power unit produced 124 hp / 91.2 kW of power. The maximum torque ranged from 3000-3400 Nm. An almost five-liter engine consumed 240 g / hp * h of fuel. It was allowed to use gasoline grades AI-76 and AI-80. Subject to additional adjustment, the engine could run on fuel with 92 octane.

Other characteristics

In addition to power unit GAZ-3307 used a mechanical five speed box synchronized gears. Front and rear suspension had a spring design. Hydraulic shock absorbers were installed on the front axle.

The working dual-circuit brake system was supplied with a hydraulic drive to facilitate braking. On the front and rear axle drums were used brake mechanisms. The car could reach speeds of up to 90 km / h maximum, and it overcame the limit from 0 to 80 km / h in 64 seconds. Taking into account all the characteristics, the car could climb up to 25 degrees. Installation of power steering was not provided.

In 1989 off the assembly line Gorky Automobile Plant GAZ 3307, the first car of the fourth generation of cars produced by the enterprise, came down. In 1994, the gasoline engine of the car was replaced with a diesel one, which significantly improved the technical characteristics of the GAZ 3307, provided the car with maximum power and performance.
