Small-duty truck Eraz-762The silk, produced at the Yerevan Automobile Plant, became one of the most recognizable symbols of Soviet logistics of the “last mile”. Unlike the more common IZH-2715 heels, this model was based on the GAZ-21 and GAZ-24 Volga units, which provided it with an increased load capacity of up to 1 ton and more comfortable handling. The design of the van type body made it possible to effectively use the internal volume for the transportation of consumer goods, mail and food in urban conditions.
Uniqueness Eraz-762 It was a combination of the chassis frame design with an all-metal car body, which was rare for cars of this class at that time. The engines installed on various modifications ranged from carburetor ZMZ to diesel units, which allowed to operate the machine in different climatic zones. Despite the discontinuation of production in the early 1990s, interest in this model persists among collectors of retro equipment and restorers, who appreciate its maintainability and simplicity.
History of the creation and development of the model
Development of a new truck for the needs of commerce and mail began in the mid-1960s, when it became apparent that existing converted passenger cars could not cope with the growing volume of freight traffic. Engineers of Yerevan Automobile Plant made a bold decision to abandon the use of ready-made GAZ chassis as the basis for the body, creating an original frame and cabin. Prototype that received an index 762It was introduced to the public in 1966 and immediately attracted attention for its spaciousness.
Serial production began in 1967, and the car quickly gained popularity due to its reliability. The basis for the power plant and transmission were time-tested nodes GAZ-21This makes it easier to maintain in any garage. The plant constantly upgraded the model, introducing new units from the GAZ-24 And experimenting with diesel engines, which was a cutting-edge solution for the Soviet automotive industry at the time.
⚠️ Note: When searching for spare parts for the restoration of the ErAZ-762, it is important to take into account the year of release, since different types of engines and transmissions were installed at different periods, which are not always interchangeable without altering the fasteners.
During the years of production, several tens of thousands of copies were produced, which worked in all corners of the USSR. The machine has proven itself as an unpretentious worker, able to work in bad roads. However, by the end of the 80s, the moral and physical obsolescence of the design, as well as the economic crisis led to the curtailment of production.
Technical specifications and design
Constructively Eraz-762 It was a frame car of a wagon layout. The driver’s cab was located above the engine, which allowed to maximize the usable area of the cargo compartment. The ladder-type frame provided the necessary rigidity and allowed to withstand the declared ton of cargo, which was a significant indicator for a machine of this class.
The cargo compartment had a volume of about 9 cubic meters and was completely isolated from the cabin. Access to the cargo was carried out through two side doors and rear doors, which made loading and unloading in urban conditions very convenient. The floor of the van was made of wooden boards on a metal base, which facilitated replacement in case of damage.
Detailed body dimensions
The length of the cargo compartment was 2.8 meters, width - 1.8 meters, height - 1.7 meters. This allowed you to load standard retail boxes and bags without much trouble.
The table below shows the main technical parameters of the most common modification Eraz-762B:
| Parameter | Meaning |
|---|---|
| Engine. | ZMZ-24D (petrol) |
| Power | 95 hp. |
| Load capacity | 1,000 kg |
| Volume of van | 9 m3 |
| Max. speed | 110 km/h |
The transmission of the car was fully synchronized with the Volga units, including a 4-speed manual transmission. The rear axle has been reinforced over the passenger prototype to cope with constant loads at full load.
Engines and modifications
During production Eraz-762 It was equipped with several types of power plants. The basic and most mass was the version with the engine ZMZ-24DIt was very reliable and affordable spare parts. This 2.4-liter engine provided enough traction for urban driving, although it was characterized by high fuel consumption.
Special attention should be paid to diesel modification Eraz-763It was powered by a GAZ-541 engine. It was the first Soviet light-duty truck with a diesel engine, which gave it advantages in economy and resource. However, the complexity of maintenance of diesel equipment and the shortage of spare parts did not allow this version to become mass.
- 🚛 Eraz-762 - Basic model with engine from GAZ-21 (ZMZ-21A).
- 🚛 Eraz-762B - upgraded version with units from GAZ-24 (ZMZ-24D).
- 🚛 Eraz-763 Diesel version with engine GAZ-541.
- 🚛 Eraz-765 - Experimental model with VAZ-2101 engine.
There were also experimental versions, including an attempt to install the engine from the VAZ-2101But they didn't go into production because of the lack of power and torque for such a mass of the car.
To save the life of the engine ZMZ on the ErAZ-762, it is recommended to strictly monitor the temperature regime and regularly check the tension of the fan belt, since overheating in urban mode with frequent stops is a frequent problem.
Operation and maintenance
In operation Eraz-762 It has proved itself as a fairly hardy car, but requiring attention to the lubrication and cooling system. ZMZ engines are sensitive to oil quality, so replacement intervals had to be reduced, especially when operating at full load. Regular lubrication of the squeakers and crosses of the driveshaft was a mandatory procedure to prevent knocking in the suspension.
The body of the van, made of steel sheets, in the absence of timely anticory treatment, was subjected to corrosion, especially in the lower part of the arches and rapids. Owners had to regularly inspect the hidden cavities and, if necessary, welding. The simplicity of the design allowed to perform most repairs by the driver himself in the garage.
⚠️ Note: When operating a fully loaded ErAZ-762, it is not recommended to exceed the speed of 80-90 km / h, since the braking system inherited from the Volga passenger car may not cope with the inertia of a ton of cargo on long descents.
The electric equipment of the car was simple and reliable, but the generator often could not cope with the increased load if additional lighting or refrigeration equipment were installed. Many drivers have independently changed the standard generators for more powerful analogues from trucks.

Comparison with competitors and analogues
The main competitor Eraz-762 in the Soviet market was IZH-2715It was also used for the transportation of goods. However, the heel of the IZH had a lower load capacity (450 kg against 1000 kg in ErAZ) and a smaller body volume. ErAZ won in the comfort of control thanks to the softer suspension of the Volga and better cabin noise insulation.
On the other hand, ErAZ was more difficult to manufacture and more expensive to maintain. If the IZH-2715 could be assembled literally from the nodes of Moskvich, then for ErAZ more scarce Volgov parts were required. In a planned economy, this was often a decisive factor in choosing equipment for the fleet.
- 📦 The YerAZ-762 had a much larger cargo compartment volume compared to the IZH-2715.
- 📦 Driver comfort in YerAZ was higher due to improved ergonomics of the cabin.
- 📦 The repair base of IZH-2715 was more accessible in provincial cities.
It is also worth mentioning the Latvian RAF-2203The silk, which was used for passenger transportation, but in the cargo version was inferior to YerAZ in the strength of the body and the ability to carry heavy loads on a permanent basis.
The key advantage of the ErAZ-762 over its competitors was its ability to carry 1 ton of cargo, remaining in the class of small-tonnage cars with dimensions convenient for the city.
Reasons for retirement and legacy
By the late 1980s, it became clear that the design Eraz-762 They have exhausted their modernization opportunities. The frame scheme and wagon layout by that time were considered obsolete, giving way to more modern hoodless trucks with a load-bearing body. The economic crisis and the rupture of economic ties led to the fact that the plant was unable to launch a new model. YerAZ-3730 on a scale that is necessary.
The last cars rolled off the assembly line in 1992. The factory tried to survive by assembling cars from the remaining stock, but the quality of the assembly was falling and demand shifted towards imported minibuses. Nevertheless, the YerAZ-762 left a deep mark on the history of the Soviet car industry as an attempt to create a specialized urban truck.
⚠️ Warning: Buying an ErAZ-762 today for a collection, carefully check the frame condition for cracks and corrosion, as restoring the load-bearing elements of the body can cost more than the car itself.
These cars are rare today, mostly in museums or private collectors. The surviving specimens are often the objects of careful restoration, returning to life in its original form.
Interesting fact.
There was a modification of the ErAZ-762P, designed for the transportation of bread, with shelves inside the body, but it was released in a very small series.
Frequently Asked Questions (FAQ)
What is the maximum speed of the ERAZ-762?
