Domestic dump trucks GAZ-3307 belong to the fourth family of medium-tonnage trucks from the Gorky Automobile Plant. The on-board version began to be produced in 1989. Five years later, the car was improved, equipped with a diesel engine and received the index 3309. The body of the model in question is a wooden platform with three hinged sides. Installation of hinged benches, arches and an awning is provided. A double cabin is located behind the power plant, has improved visibility, capacity and sound insulation, compared to its predecessors.
Device
GAZ-3307 dump trucks are equipped with a drum brake system, the diameter of the front and rear linings is 38 centimeters, their width is 8 and 10 cm, respectively. In sludge mode, a transmission drum brake with an operating diameter of 22 centimeters and a lining width of 6 cm is additionally used. The drive of the assembly is mechanical, any circuit of the indicated unit 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 combs. Regarding electrical equipment:
- working voltage - 12V;
- battery - 6CT-75;
- voltage controller - G250-G2;
- Starter - 230-A1;
- ignition coil - B-114 with the TK-102A switch.
In addition, valves, spark plugs and wiring are included.
Powertrain
The GAZ-3307 car, with a carrying capacity of 4.5 tons, is equipped with a ZMZ-5321-10 motor (carburetor type). The four-stroke gasoline engine has eight cylinders with a high output power rating. The fuel system has liquid cooling and exhaust exhaust gas recirculation.
The cylinder block is made of aluminum alloy, there is an additional OHV valve assembly. The class of compliance with the standards of the power unit is equal to "Euro 3". The maximum engine speed is three thousand four hundred rotations per minute. With these parameters, the vehicle's power is 124 horsepower, and the volume is five liters. Fuel consumption is at a level of 240 g / l. s / h Acceptable fuel is AI 76 or 92 gasoline.
Overall indicators
GAZ-3307 dump trucks have the following parameters:
- length / width / height - 6.3 / 2.3 / 2.35 meters;
- wheelbase - 3.77 meters;
- clearance in the rear axle is 26.5 centimeters;
- track (front / rear) - 1.7 / 1.56 m;
- the length of the cargo base is 3.5 meters;
- width / height of the platform - 2.17 / 0.51 m;
- load indicator - 4,500 kilograms;
- curb / gross weight - 3.2 / 7.1 tons.
On most versions, a hydraulic cylinder for lifting the body, a five-speed synchronized mechanical-type gearbox and a spring suspension design were used.
Exploitation
The GAZ-3307 engine allows you to develop a top speed of more than ninety kilometers per hour. Acceleration to eighty km / h is a little over 60 seconds. The average fuel consumption is in the range of 19-25 liters per hundred kilometers. The minimum climbable climb is 25 degrees. The fuel tank holds 105 liters of gasoline.
The truck is widely used in construction, agricultural, communal spheres. Main application:
- transportation of sand and other bulk cargo;
- transportation of building materials and agricultural products;
- removal of household and industrial waste;
- the use of a vehicle for the transport of special crews and goods.
The workplace for the driver has also undergone modernization. The GAZ-3307 car was equipped with a double spacious cab, which provides for a heating and ventilation system. The mounted 4 * 2 formula and the ZMZ motor do an excellent job of driving on paved roads. Simplicity in operation and repair, coupled with an affordable price and good performance, are the main aspects that influenced the popularity of the car in various business sectors.
Features
GAZ-3307 dump trucks in the presence of objective advantages have a number of obvious disadvantages. The negative points include the following:
- a sensitive suspension makes off-road driving virtually impossible;
- the oil seal on the crankshaft begins to leak quickly;
- the power plant is not economical;
- some components fail early.
At the same time, the hydraulic cylinder for lifting the body and several other successful design decisions made the truck one of the most optimal options for its time. The upgraded version of the car began to roll off the assembly lines back in 2008. The working double-circuit brake unit was equipped with a hydraulic drive to facilitate braking, but the power steering was not provided in the basic configuration.
Recommended types of engine oils and fluids
In order for the GAZ-3307 engine to work out its life without additional intervention, it is recommended to use oils of category M6 / 8/10 V or ASZp-6 (for severe frosty conditions). The gearbox gets along well with a lubricant like TSp 10-15, which is also quite suitable for the steering gear.
It is advisable to maintain shock absorbers using spindles or liquid -12. The brake system digests the manufacturer's recommended suspension called Tom. Modern oils and fluids may also be suitable for use after consultation with specialists. For cooling, the A-40 antifreeze refrigerant in diluted form or a pure analogue under the A-65 index is most often recommended. Thanks to the heater, the driver and passengers will feel comfortable in the cockpit even during particularly cold weather.
Auto cost and customer reviews
Depending on the condition of the car and the year of its release, the price of the truck in question is from sixty thousand to half a million rubles. Judging by user reviews, the car is quite popular. Most of all, consumers value the load capacity, exterior and comfort of the cab.
Consumers mention that the vehicle is unpretentious, easy to maintain and operate, “eats” gasoline with an octane rating from 76 to index 92 (with the introduction of certain design improvements). Not the last role in the popularity of cars played an affordable price and the availability of spare parts. Tippers are still used in private enterprise and in various sectors of the national economy. The negative aspects of the owners include poor off-road patency, the instability of some nodes and excessive "gluttony" of the vehicle.
Conclusion
The domestic car GAZ-3307, with a carrying capacity of more than four tons, proved to be an aggregate used to transport various bulk cargoes. It is not afraid of frost, it is mainly used on hard surfaces, and has good technical indicators.
Judging by user reviews and the reactions of specialists, the truck in question has some flaws. However, they overlap with ease of use, unpretentiousness and affordable price. Another 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.
