GAZ-3307 dumpers: device and specifications

Domestic dump trucks GAZ-3307 belong to the fourth family of trucks of medium tonnage from the Gorky Automobile Plant. The onboard version began to be produced in 1989. Five years later the car was improved, equipped with a diesel engine and received an index of 3309. The body of the model in question is a wooden platform with three flaps. The installation of hinged benches, arches and awning is provided. The two-seater cabin is located behind the power unit, has improved visibility, capacity and noise insulation, in comparison with its predecessors.

Device

GAZ-3307 dump trucks are equipped with a drum brake system, the diameter of the front and back lining is 38 centimeters, their width is 8 and 10 cm, respectively. In the sludge mode, a transmission drum brake with a working diameter of 22 cm and a liner width of 6 cm is additionally used. The unit drive is mechanical, any contour of the block can be used as a spare element.
The steering of the truck is a worm gear equipped with a gear ratio of 21.3, as well as a roller with three ridges. Regarding electrical equipment:

• Working voltage - 12V;
• Battery - 6ST-75;
• Voltage controller - Г250-Г2;
• Starter - 230-A1;
• Ignition coil - B-114 with switch TK-102A.

In addition, this includes distributors, spark plugs and wiring.

Power unit

The GAZ-3307, with a carrying capacity of 4.5 tons, is equipped with a ZMZ-5321-10 engine (carburetor type). The petrol four-stroke engine has eight cylinders with a high output power rating. The fuel system has liquid cooling and recirculation of exhaust emissions.

The cylinder block is made of aluminum alloy, there is an additional valve unit OHV. The class of compliance with the standards of the power unit is equivalent to "Euro 3". The limiting rpm of the motor is three thousand four hundred revolutions per minute. With such parameters, the vehicle's power is 124 horsepower, and the volume is five liters. The use of fuel is at the level of 240 g / l. S / h. Acceptable fuel is gasoline AI 76 or 92.

Dimensions

GAZ-3307 dump trucks have the following parameters:

• Length / width / height - 6.3 / 2.3 / 2.35 meters;
• Base wheel - 3.77 meters;
• The clearance in the area of the rear axle is 26.5 centimeters;
• Track (front / rear) - 1,7 / 1,56 m;
• The base of the cargo compartment along the length is 3.5 meters;
• The width / height of the platform is 2.17 / 0.51 m;
• Index of carrying capacity - 4,500 kilograms;
• Loaded / full weight - 3,2 / 7,1 tons.

On most modifications, a body lifting hydraulic cylinder, a five-speed synchronized gearbox of mechanical type and a spring suspension design were used.

Exploitation

The GAZ-3307 engine allows to develop a top speed of more than ninety kilometers per hour. The acceleration time to 80 km / h is just over 60 seconds. The average fuel consumption is in the range of 19-25 liters per hundred kilometers. The minimum climb is 25 degrees. The fuel tank holds 105 liters of gasoline.

The truck is widely used in construction, agrarian, communal areas. Main application:

• Transportation of sand and other bulk cargo;
• Transportation of building materials and agricultural products;
• Removal of domestic and industrial waste;
• The use of a vehicle for the transport of special brigades and cargo.

The workplace for the driver has also undergone modernization. The GAZ-3307 was equipped with a double spacious cabin, in which a heating and ventilation system is provided. The hinged formula 4 * 2 and the engine ZMZ perfectly cope with movement on roads with a hard coating. Simplicity in operation and repair, coupled with an affordable price and good characteristics - the main aspects that influenced the popularity of the car in various business sectors.

Features

GAZ-3307 dump trucks have some obvious shortcomings in the presence of objective advantages. The negative aspects include the following:

• Sensitive suspension makes off-road driving almost impossible;
• The oil seal on the crankshaft starts to flow quickly;
• The power plant is not economical;
• Some component elements fail prematurely.

At the same time, the body lifting hydraulic cylinder and several other successful design solutions made the truck one of the most optimal options for its time. The upgraded version of the car began to go off the assembly line in 2008. The working dual-circuit braking unit was supplied with a hydraulic drive to facilitate braking, but the power steering was not provided in the basic configuration.

Types of motor oils and fluids recommended for use

For the GAZ-3307 engine to work its life without additional intervention, it is recommended to use oils of the category M6 / 8 / 10V or ASZp-6 (for severe frost conditions). The gearbox works well with a lubricant type TC-10-15, which is also quite suitable for steering gear.

Shock absorbers should be serviced with a spindle or liquid АЖ-12Т. The brake system digests the manufacturer's recommended suspension called "Tom". Modern oils and liquids can also be suitable for use after consultation with specialists. For cooling, refrigerant tosol A-40 is usually recommended in diluted form or pure analogue under the A-65 index. Thanks to the heater, the driver and passengers will feel comfortable in the cockpit, even at a particularly young age.

Car cost and consumer reviews

Depending on the condition of the car and the year of its release, the price for the truck in question is from sixty thousand to half a million rubles. Judging by the feedback from users, the car is quite popular. Most of all, consumers appreciate the carrying capacity, the exterior and the comfort of the cabin.

Consumers mention that the vehicle is unpretentious, easy to maintain and operate, "feeds" gasoline with octane number from 76 to 92 (with the introduction of certain design improvements). Not the least role in the popularity of the car was played by an acceptable price and the availability of spare parts. Tippers are still used in private business and various sectors of the national economy. To the negative moments, the owners refer to bad off-road ability, instability of some units and excessive "gluttony" of the vehicle.

The domestic car GAZ-3307, the carrying capacity of which is more than four tons, proved to be an aggregate used for transportation of various bulk cargoes. It is not afraid of frosts, it is mainly operated on a hard surface, it has good technical indicators.

Judging by the feedback from users and the reaction of experts, the truck in question has some flaws. However, they overlap with ease of operation, unpretentiousness and affordable price. Extra confirmation of the popularity of the GAZ-3307 is its serial production for several decades. Each subsequent modification has a number of improvements and improvements.
