History of creation

GAZ 3507 is one of the latest developments of the Gorky Automobile Plant (production began in 1984). The model was considered as a replacement for the GAZ 3307, the production of which ended in 1994. Engineers at the Gorky Automobile Plant decided to unify the models as much as possible by unit, which ensured the reliability of the design and reduced development costs. As a result, the GAZ 3507 retained most of the components from its predecessor, including a large hooded cabin and angular contours. The interior of the cabin has been redesigned, improving the heating and ventilation systems. There are new floor mats in the interior. GAZ 3507 received a completely redesigned rear frame of shorter length. The tow hooks have been replaced with a towing device, and the spare wheel has been moved rearward by 272 mm. The changes also affected the line of power units.

It is noteworthy that the GAZ 3507 was considered as a transitional model, which was later supposed to be replaced by a diesel version with greater efficiency. In the 1990s, the Gorky Automobile Plant began producing its own engines for cars, but after the collapse of the USSR, the enterprise was gripped by a crisis, as a result of which the production of engines and cars (gasoline GAZ 3507 and diesel GAZ 3507-01, GAZ 35071) sharply decreased.

However, production of the model did not stop completely. Moreover, in 2003, the Saransk Automobile Plant revived the car by creating a new version of the GAZ 35072, the basis for which was the GAZ 3309 model, equipped with a Belarusian D-245 diesel unit. The car became more economical than its predecessor and was practically not inferior to it in terms of technical characteristics. GAZ 35072 also retained the design of the original version. The carrying capacity of the machine was 4250 kg (only one-sided unloading was allowed).

In 2009, production of gasoline versions of the GAZ 3507 ended. The release of other models is currently ongoing.

Modifications

Supplied under the designation GAZ-SAZ-35071, the dump truck is equipped with a diesel power unit. The increase in engine weight led to an increase in the total weight of the car, which reached 8090 kg. Early releases used a 125-horsepower MMZ D-245.7 unit, which was later replaced by a 135- or 149-horsepower YaMZ-534 engine. A 3-seater cabin is used as standard, but a 5-seater 2-row unit can be used.

The dump truck, shipped under the symbol GAZ-35072, was designed for transporting construction materials. The machine is distinguished by the use of an all-metal platform with a folding tailgate. The side parts are made beveled, which ensures increased strength of the unit. The standard equipment includes a short protective visor that covers part of the driver's cabin. There is a ladder at the back of the platform. The vehicle is designed to transport cargo weighing 4000 kg, the body capacity is 5.4 m³. It is possible to install a protective awning, which reduces the risk of cargo blowing out.

The GAZ-SAZ-3507-01 modification is distinguished by the use of a 125-horsepower gasoline engine equipped with an exhaust gas neutralizer without the ability to adjust the mixture composition. Some cars produced after 2016 have a modernized engine equipped with a fuel injection system. The unit develops a power of 137 hp and complies with Euro 4 standards. A standard type dump platform is installed, designed for 5 m³ of cargo.

The variant version of GAZ-SAZ-35072-10 is distinguished by the design of the platform lift, which allows only one-sided unloading to the rear. Because of this, the side sides are made motionless, only the rear section reclines. The standard body has a capacity of 5 m³, the use of extension sides allows you to increase the volume to 10 m³.

Peculiarities

GAZ-SAZ-3507 dump trucks have been really popular for a very long time, but the demand for them has not disappeared even today. This is due to the fact that the model has proven itself to be an unpretentious machine, easy to operate and maintain. Also, many owners note that the equipment is very versatile and can work in many areas, from agriculture to the construction of any objects. But, despite all its advantages, the truck also has quite a few disadvantages.

First of all, mention should be made of the poor quality of the metal used in the construction of the cargo platform. Because of this, the car body quickly becomes covered with rust.

But in addition to corrosion, systematic heavy loads can also have a negative impact. Moreover, this has been proven many times in practice, since most often the truck is operated with overload on board. The consequence of this is metal separation at joints and sometimes even at welds. This problem cannot be solved even by installing various reinforcements in the form of additional channels and strips.

Another common problem is the occurrence of leaks in cuffs and hoses in the hydraulic system.

Other serious malfunctions occur quite rarely with this truck; minor breakdowns are more common. They can be eliminated with almost a minimum set of tools and in a short time. This feature is explained not only by the wide distribution and availability of spare parts and consumables, but also by the simplicity of the design. Even the most seemingly complex truck components can be repaired independently. Thanks to this, the GAZ-SAZ-3507 model remains a very popular, simple and reliable vehicle, which also has a low cost.

Overframe device

The overframe device for mounting a dump cargo platform is made in the form of 3 separate units: front and rear beams, plus an overframe.

The front beam is a hollow beam made of bent metal profile. Two brackets for installing rubber buffers are welded to the upper plane of the beam, and brackets for attaching it to the car frame are welded to the lower plane. At the ends of the beam, using side plates, the support axes of the front support brackets of the platform are welded, as well as the mounting brackets for the front side light and side protection.

The subframe is a welded frame structure that is bolted to the vehicle frame. It consists of two longitudinal beams, which are connected by cross members. A hydraulic cylinder support with a support heel is welded to the crossbars. Here, using four bolts and a mounting cover, the lower ball joint of the hydraulic cylinder is installed. There is a safety stop on the left longitudinal beam of the subframe - for fixing the platform raised back. There are also rubber buffers on the subframe.

The rear beam is also made of a rectangular profile. Support brackets and supports are welded to its upper plane, with which the rear rotating bearings of the platform interact, and brackets 16 are welded to the side and lower planes for attaching this beam to the car frame. Brackets for attaching tail lights, license plate holder, rear side marker light and contour light are also welded to the rear beam.

To soften dynamic impacts and reduce noise (in particular, when driving a dump truck with an empty body), rubber buffers are provided. Four special clamps are designed to fix the cargo platform in its transport position.

Body description

The manufacturer installs a steel body with folding sides on the base chassis. Unloading can be done to both sides and to the back.

Optional installation available:

• Frame with awning;
• High-height extension sides;
• Board assistants;
• Side seals.

The dump truck's passport indicates that it has an agricultural purpose and is suitable for unloading. The hydraulic drive ensures lifting and tilting of the body.

About the enterprise Saransk Dump Truck Plant

The enterprise traces its history back to 1960, when in the capital of Mordovia the resolution of the Mordovian Council of National Economy dated August 11, 1960 No. 151 “On the organization of the Saransk dump truck plant” began to be implemented. From the very beginning of its work, the plant’s task was to develop and produce dump trucks (mainly for agricultural purposes) on truck chassis from the Gorky Automobile Plant. Later, car trailers and semi-trailers for trucks were also added to the list of products.

By 1991, the Saransk dump truck plant produced more than 1 million 200 thousand dump trucks and special vehicles (garbage trucks, vans, road trains with semi-trailers) on the chassis of GAZ trucks. And also more than 35 thousand trailers and semi-trailers.

The most popular model of the plant...

According to the experience of SAZ, a smaller similar production was launched and existed for 25 years in the capital of Kyrgyzstan - the city of Frunze. The same GAZ-SAZ vehicles were produced there, according to documentation from Saransk specialists. The products of the Saransk Dump Truck Plant have repeatedly been highly noted at the all-Union level. First of all, it is a “people’s” agricultural dump truck based on the GAZ-53 car.

In 1992, the enterprise was transformed into the open joint-stock company Saransk Dump Truck Plant (SAZ OJSC). It survived the years of “democratic” hard times, and in modern times it has expanded its range of products. Today, in addition to dump trucks on the GAZon Next and GAZelle Next chassis, containers and bunker bodies for solid waste collection for garbage trucks; These also include seven models of car trailers - for trucks and cars, small-sized woodworking machines, furniture, 60 types of spare parts for agricultural machines.

...and its current products.

Working with a dump body

The hydraulic system of the dump truck GA3-SA3-Z507 is controlled by two levers - the power take-off control lever and the control valve lever. These levers are located in the cockpit, to the right of the gear lever. The control valve lever also has 2 positions: “lowering” and “neutral”. The control valve is three-valve, ball type.

To tip the body, you need to place the PTO control lever in the extreme forward position along the vehicle's path, with the engine on and the clutch disengaged.

When the clutch is engaged, the power take-off box with the oil pump is engaged, and oil from the reservoir tank begins to flow under pressure through the discharge line into the hydraulic cylinder. Under the influence of increasing oil pressure, the hydraulic cylinder plungers begin to extend, ensuring the body tipping. Before turning on the power take-off to tip the body, you need to make sure that the platform latches are released correctly.

Unloading backwards is carried out with a smooth movement of the vehicle forward one and a half/two meters in order to prevent the tailgate from resting on the dumped cargo. It is not recommended to accelerate unloading through sudden jerks of the platform or sudden movements of the dump truck itself.

After making repairs related to the removal of components and parts of the hydraulic system of the dump truck, you should remove air from the hydraulic system: make several lifts of the empty platform in a row. To flush the hydraulic system, the manufacturer recommends using only low-viscosity oil; gasoline or kerosene - not recommended.

You cannot drive with the body raised, with the power take-off switched on, and without securing the platform with all 4 latches. You cannot increase the sides of the cargo platform additionally to increase its volume by more than ten cubic meters.

GAZ-33086 “Countryman”: dump truck from the Gorky plant

The GAZ-33086 “Countryman” dump trucks became the progenitors of a whole model range of vehicles on a basic all-wheel drive chassis. The equipment was specially created for difficult terrain. Moreover, the versatility of the machine allows it to be used both in agriculture and construction.

GAZ-33086 "Countryman" dump truck: technical characteristics

GAZ-33086 “Countryman” dump trucks are designed for transportation of bulk industrial and agricultural cargo. On the basis of chassis 33086 of the Gorky plant, GAZ-SAZ-2506 vehicles were created, which, in fact, became dump trucks. The cross-country ability of the chassis and the high load capacity of the base equipment made it possible to obtain a universal product suitable for difficult conditions.

Body

In a dump truck, special attention is paid to the body structure. The GAZ-SAZ-2506 dump truck based on the GAZ-33086 “Countryman” is equipped with a metal straight-sided body, to which, at the customer’s request, extension sides are supplied. Lifting is carried out by a hydraulic mechanism with one cylinder. The dump truck is controlled mechanically.

Cabin

The cabin was removed using a tractor on our own, but to remove the body we had to call a fiskar. They dismantled their original engine, and all that remained was a bare frame with wheels.

The front beam was removed, the gas 53 rear axle too, the frame was cleaned with a grinder, there weren’t even any shock absorber mounts left. The frame was left completely bare; we dragged it closer to the gate, since the other day we were supposed to bring a well-preserved frame from the bus.

Chassis

The frame has a stamped, riveted design. At the same time, for the GAZ-3507 (SAZ) car it was slightly changed. So, they installed a rear frame shortened by 0.152 m, and the spare wheel was moved back 0.272 m. In addition, towing device 33072 was replaced with towing hooks for GAZ-SAZ-3507. The specifications below differ for each version. Only the wheelbase for all variants is 3.77 m, the front track is 1.69 m, and the rear track is 1.63 m.

Performance

The engine determines many of the performance characteristics of the GAZ-SAZ-3507. Thus, it is possible to transport 4.125 tons of cargo (4.325 tons with extension sides) on the 3507-01 model and 4.1 tons on the 35072. At the same time, the curb weight of the first modification is 3.6 tons (extension sides increase it by 200 kg) , full - 8 tons. For 35072, similar parameters without extension sides are 3.69 tons and 7.94 tons, respectively.

on the auxiliary frame. Along the perimeter the platform has sides that fold down at the back and sides. The folding elements are mounted on swivel hinges and equipped with special devices to facilitate closing. Fixation is done manually. At the right moment of unloading they open.

In the standard version, the height of the sides of the dump truck is 62 cm. They can be increased to 1.25 m using add-on panels. Increasing the height allows you to get 2 times more body volume. Thus, the capacity increases, which is convenient when transporting large and light loads.

Tilting hydraulic cylinder

Tipping hydraulic cylinder GAZ-SAZ-35071

The GAZ SAZ-35071 platform tips over when the telescopic hydraulic cylinder is turned on. It consists of 3 elements providing a maximum stroke of 670 mm. A 16 liter hydraulic oil reservoir is located on the frame. The pressure in the hydraulic drive is created by an NSh 32UK-3 gear pump located on the PTO. Torque to the pump drive is transmitted from the intermediate shaft of the gearbox.

The required direction of unloading is set by the control valve switches. In the raised position, the platform is fixed with a mechanical stop. The driver controls the unloading and lifting of the platform directly from the cab. One lever turns on the power take-off, and the second selects the direction of unloading. The levers are located on a special panel with cutouts located on the floor.

How to determine the malfunction?

If you have an electrical diagram on hand, you can easily use it to determine a malfunction in the operation of one or another element. To diagnose a breakdown, you will need a test lamp with cables and crocodiles, as well as a multimeter, which should be activated in advance to the voltmeter operating mode. One clamp from the control should be connected to the input contact of the node that you are diagnosing, and the second to ground, that is, to the body or engine of the vehicle or the “-” output of the battery.

Important How to repair and balance the KamAZ crankshaft

In accordance with the diagram, it is possible to determine which route the voltage takes from the battery to the diagnostic site; accordingly, the voltage should be diagnosed at all contacts of this section. If there is voltage on all contacts and elements of the circuit, the multimeter must be switched to ohmmeter mode and its terminals connected to the ends of one or another wire. If there are no breaks in the circuit, the arrow will deviate; if there are, then it will not move. To restore the functionality of a certain section of the circuit, you need to find a break and eliminate it. When diagnosing, it should be taken into account that electrical equipment often comes into operation when the ignition is activated (video author - Time Auto).

In the chassis of the GAZ-SAZ-35071 model, the rear axle is driven, and the front axle is driven. The chassis includes a dependent leaf spring suspension. Telescopic hydraulic shock absorbers are located on the front axle.

The braking system is dual-circuit, with drum mechanisms installed on all 4 wheels. Steering drive unit - without power steering.

Dumping device for loading platform

The loading platform of the GA3-SA3-Z507 dump truck is raised and tipped using a hydraulic cylinder 3507-01-8603010-01. It is telescopic, single-acting, with three retractable plunger links. The total stroke of the links is 695 mm. The tipping mechanism lifts and lowers the platform, stopping it in any intermediate position; The pressure limit in the hydraulic system is no more than 115 - 120 kgf/cm2.

The lower and upper ball joints of the hydraulic cylinders are located in the centers of the lower part of the body and subframe. The desired tipping side is selected by the driver by releasing the removable hinge pins at the base of the platform. If the stall is to the left, the driver releases the two right hinges; right - vice versa; if the stall is rear, then two front ones.

Energy is transferred from the engine to the platform raising mechanism using a power take-off controlled by a lever from the cab. The power take-off is mechanical, single-speed, combined with a pump and control valve. The PTO lever has two locking positions: “lift” and “neutral”. The hydraulic system filling capacity holds 16 liters. An NSh-32U-3 oil pump is placed on the power take-off housing, and behind the cab, between the frame and the body, there is an oil tank made of thin stamped steel sheets.

STORY

In Soviet times, the Gorky Automobile Plant was considered one of the main manufacturers of medium-duty trucks. After the collapse of the USSR, the company lost its position, but some models of the brand remain in high demand on the market.

GAZ 3507 is one of the latest products of the Gorky Automobile Plant. Production of the car started in 1984. The well-proven GAZ 3307 was used as the basis for its creation. The model was a great success in the Union republics, but by the beginning of the 1980s it began to become obsolete. The developers wanted to create a new model at minimal cost and preserve the advantages of its predecessor. As a result, the priority became maximum unification of elements and nodes. Many units and parts of the GAZ 3307 were “migrated” into the design of the GAZ 3507, which made it possible to significantly save on the development process. The design has remained virtually unchanged. GAZ 3507 received the cabin of its predecessor with a large hood, standard angular shapes and a large radiator grille. The cabin of the new series has become larger and has improved heating and ventilation systems.

The GAZ 3507 differed from the previous version by a rear frame shortened by 152 mm. Changes in appearance were minimal. The spare wheel has moved 272 mm back. The towing hooks used in the GAZ 3307 were replaced with a towing device. The casing and floor mats have been completely changed. The remaining elements have been preserved in the same format.

Transformations took place in the engine line. GAZ 3507 was considered as a transitional series, which was supposed to be replaced by a more economical and modern model. To achieve this goal, in the early 1990s, the Gorky Automobile Plant opened the production of its own engines, but after the collapse of the USSR, the enterprise was gripped by a severe crisis. As a result, car production decreased noticeably, and the transitional model is still available on the market today.

Initially, the new series consisted of 2 modifications: GAZ 3507 (a dump truck based on the GAZ 3307 with a ZMZ-5231 gasoline engine, a load capacity of 4.13 tons and a body volume of 5 cubic meters) and GAZ 35071 (a diesel variation with similar characteristics). In 1989, a new generation of GAZ 3307 was introduced, on the basis of which modifications GAZ 3507-01 and GAZ 35072 were created.

The series expanded in the 2000s. After the appearance of the GAZ 3309 chassis, the premiere of the new version of the GAZ 35071 took place. However, truck sales continued to decline.

In 2003, the Saransk Automobile Plant tried to revive the series and launched the GAZ 35072. The model was based on the GAZ 3309 chassis with the Belarusian D-245 diesel unit. The car had a 4.5 cubic meter body, one-sided unloading and had a load capacity of 4.25 tons. Compared to other versions of the GAZ 3507, the new product was much more economical and required 14 liters of fuel per 100 km, practically not inferior in power and traction to the classic version. In terms of design, the GAZ 35072 was no different from the base model.

In 2009, production of gasoline modifications ended.

GAZ 3507 remains in demand in the domestic market. The production of the series on a small scale continues to this day.
