Dump truck GAZ-3307 is a time-tested vehicle

On this page we will focus on the technical characteristics of the GAZ 3307 truck.

This vehicle is classified as an onboard vehicle. The driving wheels are the rear ones. GAZ 3307 weighs a little, quite a lot 3750 kg. But its carrying capacity is less - 4.5 tons. But it can reach speeds of up to 90 km/h, with a maximum engine power of 120 hp.

Front suspension Gas 3307

GAZ 3307 dump trucks and some other modifications of the GAZ 3307 model range were equipped with diesel engines adapted to work with a five-speed manual transmission. Speed ​​shifting was carried out by a friction single-plate clutch with a hydraulic drive. When installing a gasoline engine on a GAZ 3307 car, a four-speed gearbox was installed, one of the serious drawbacks of which was a characteristic howl while driving.

GAZ 3307 vehicles have a dependent suspension. Shock absorbers with semi-elliptical springs are installed on the front wheels. The shock absorbers on the rear wheels have been replaced with additional springs. The ends of the main sheets are installed in support brackets, in rubber cushions.

The GAZ 3307 brake system is considered one of the most reliable even today. The hydraulic brake drive is equipped with redundant brake circuits, with one of the circuits controlling the spare brake. Each circuit includes a vacuum hydraulic booster, a vacuum cylinder with a blocking valve. The cylinders provide independent power supply to the circuits. The parking brake is installed on the transmission. Braking of the GAZ 3307 car is carried out by drum brake mechanisms.

Cabin

There is more free space inside. The dashboard received an abundance of all kinds of sensors. A two-spoke steering wheel with a thin rim was installed in front of them. Among the largest sensors on the dashboard are the round powertrain speed sensor on the left and the speedometer mounted in the center.

In addition to them, there are sensors for oil, engine temperature, fuel level, battery charge and pneumatic system. More modern vehicles have fairly good seats with moderate lateral support.

To the right of the driver you can see the gearshift lever, which has a curved appearance. The entire front panel is made of plastic, and the door cards are made of pleasant fabric material.

The driver's seat itself has a sprung type, but the previous model did not have this. Moreover, the chair can be adjusted according to the angle of the backrest and in the horizontal plane.

Despite the fact that the truck cabin was developed in accordance with the standards of the Soviet era, and it had angular shapes, when compared with its predecessors, there was more free space, which, in turn, had a positive effect on comfort.

On the false panels of the doors, auxiliary side pockets appeared, which made it possible to store various small things in them. We also worked on good thermal insulation, which increased the level of comfort, and it became much more pleasant to stay inside the truck. The cabin itself was borrowed from the experimental GAZ-4301 car, which was introduced in 1984.

It had increased dimensions and was designed for a couple of people, including the driver. The main controls were fairly easy to reach. It’s very nice that they began to install seat belts, a modern instrument panel along with soft upholstery on the interior panels and doors.

What motor oils and fluids to use

For the lubrication system, it is recommended to use all-season oil M-8V or M-6/10V. But if you work in severe frosty conditions, then you will need ASZp-6 oil. For the gearbox, it is better to use all-season oil TAP-15v, from minus 25 to minus 30, use TSp-10, and if the temperature is even lower, then fill in TSp-15K with a small addition of diesel fuel for diesel gas 3307. The same oils Can also be used for steering gear. The main gear housing should be filled with all-season oil TSp-14gip; in very severe frosts - TSz-9gip. For shock absorbers you will need AJ-12T fluid, or spindle oil. Use Tom as brake fluid.

Of course, all this data is taken from the manufacturer's recommendations, and if necessary, you can use modern oils or fluids. But do not forget to consult with specialists.

Curb weight 3200 kg. Including: front axle 1435 kg. on the rear axle 1765 kg.

Dump truck GAZ-3307

The “parents” of the GAZ-3307 truck, on the basis of which this dump truck was created, are the designers of the Gorky Automobile Plant. The car came to replace the GAZ-53 model, which was pretty outdated by the nineties. It was necessary to improve technical parameters and update the design.

The first sample of the new dump truck rolled off the assembly line in 1989, and by the end of this year mass production was launched. Later, this unit was somewhat displaced by the GAZ-3309 model with a diesel engine. But in 2008, the GAZ-3307, which received a new carburetor engine with increased power, began to be produced again (until 2012).

Purpose

Gas-3307 diesel is designed for transportation and quick unloading of all kinds of bulk substances. It is especially convenient to use it in agriculture, since it overcomes dirt roads well, transporting grain, potatoes, beets, hay and other crops from the fields. While collective farms were still alive, such dump trucks were an indispensable attribute of every machine yard.

However, even today the GAZ-3307 is successfully used by farmers. Such vehicles are also suitable for transporting various building materials - for example, crushed stone, sand, gravel, expanded clay.

Peculiarities

The car received the chassis and carburetor unit from its predecessor, the GAZ-53. Its main features:

• A powerful motor that allows you to move at a good speed (up to 90 kilometers per hour). To quickly warm up the engine in cold weather, a pre-heater has been introduced.
• The driven rear axle and three-way manual gearbox (there are four forward gears and one reverse gear).
• Spacious cabin for two people with panoramic glass with great visibility, heating and ventilation system. The comfortable soft seat is adjustable, the windows open mechanically.

Increased ground clearance makes it easy to ford small rivers and not get stuck in the mud in bad weather.

• The dump truck began to have a greater carrying capacity - it increased to 4.5 tons.
• Large fuel tank – 105 liters.

Device

Body

The metal body is tilted hydraulically, and an electro-pneumatic mechanism controls this process. The body platform is equipped with three folding sides. They must be closed manually, and the platform is controlled by levers in the cockpit.

Depending on the design, these dump trucks can be unloaded in two ways. In the first case, the platform leans back, tilting 50 degrees. The second option is more convenient; it involves unloading in three directions (back, left and right). The platform tilts sideways up to 45 degrees.

Engine

A powerful four-stroke engine with eight cylinders arranged in a “V” shape runs on gasoline. Suitable grades are AI-80 or AI-76. If fuel with a higher octane number was used, then the ignition system (it is non-contact) had to be pre-adjusted. There is a pre-heater.

The engine has a liquid-type cooling system, and exhaust gases pass through a recirculation device for cleaning. There is an OHV valvetrain located at the top of the engine. Aluminum cylinder heads have helical inlet ports and highly turbulent combustion chambers. Lubrication occurs in two ways: by spraying and under pressure.

Steering

The steering wheel of this car is controlled only mechanically - it does not have a hydraulic booster. The three-joint steering column is attached with four bolts to the bracket on which the brake and clutch pedals are located. Two bearings are used to rotate the steering shaft. Both tubular tie rods are mounted on hinges that are not adjustable.

The worm type transmission consists of a globoid worm and a roller with three ridges. They are connected in such a way that when the car is moving in a straight line, free rotation of the steering wheel is impossible.

If it is necessary to turn right or left, then a free turning angle occurs (its maximum value is 30 degrees). The dump truck moves in the desired direction, and there is no wobble at the front wheels.

Brakes

The car has three brake systems:

1. The working system acts on all shoe mechanisms of the wheels of the unit (on each axle separately). In each of the two circuits it has a hydraulic vacuum amplifier, as well as a supply vacuum cylinder with a valve. The movement of the pistons of the common brake cylinder is carried out by pressing the brake pedals. As a result, excess pressure is created in the hydraulic drive, which causes the drum brakes to operate.
2. The spare system serves as a backup. It represents a separate circuit of the working system.
3. The parking system only works with the rear wheels of the car. It is needed when holding the car on a slope, as well as while parking. Its drive is mechanical, cable. Turned on by lever.

Electrics

A single-wire electrical system with an alternator, rectifier and transistor voltage regulator produces 12 V. There is also a 75 Ah battery, which is connected to the unit body through a switch. Electricity powers the headlights, headlights, taillights, pre-heater, starter, windshield wiper, and ignition.
