MAZ-502 – Soviet truck, which he served faithfully for many generations of Soviet citizens. He produced as much as 9 years from 1957 to 1966. MAZ-502 memorable for its reliability and large tractive power, which is due to the all wheel drive gave the opportunity to carry large loads.
The Thought of MAZ-502 as an army truck. During the development process it established many types of chassis and platforms, but in 1955, with rolled off the first representative of this model. Soviet trucks of that time were similar to each other and differed little. So, analogs 502 models were the GAZ-53 and ZIL-130. Of course, MAZ had a greater capacity and power than its counterparts, so it first took service in the Soviet army.
But despite all positive qualities, 502 were discontinued in 1966. Although it is still exploited on the territory of the great country of about 20 years. Some cars were converted to transport army personnel, but they were replaced by the no less legendary GAZ-66, in which the permeability was higher.
Cabin 502 th was made in the classic style 50-60 years. Front heavy hood contained a “heart” of the machine – engine. The access to the unit was fine, which simplified the repair work.
The frame of the cabin had been built and made of high quality steel that would not let him succumb quickly to corrosion. Front glass and high Seating position gave a great review to the driver. Bed in 502nd MAZ was absent. This feature differed all Soviet trucks.
The Instrument panel has been simplified with a minimal set of sensors and controllers. Since the engine had no electrical equipment, like modern trucks, the devices showed compression speed, the amperage of the battery.
Since the MAZ-502 was intended as a military truck, the first steel box body for the transport of personnel and tent platform to transport army goods. The following modifications of steel and timber technical-test platform.
And only in 1961, some serial batch truck stopped supplying the body and installed trailer hitch. This allowed us to cling to 502 trailers for long-haul tractors that were used to transport bulky cargo, missiles and test rigs.
Rama was performed of the channels that were made from high quality forged steel type. The degree of deformation was too high, about 16-17 kg/1 sq cm. This is quite a lot, since frames modern truck stand about 2-4 kg/cm 1 kV. So MAZ was not afraid of any collisions.
In 1965, was conducted a series of tests aimed at increasing engine power. Even method was used water injection in the engine. But they all failed, because the motors quickly failed.
MAZ-502 had at that time quite a powerful performance. The truck was equipped with a 4-cylinder engine yaz-204V. This 135-horsepower diesel engine had a stroke of 127 mm and a cylinder diameter 108 mm. the Volume of this diesel engine was 4654 cubic cm the Main power block and head were made of cast iron, which is typical for trucks of the 50-ies of the issue. Fuel system had a fuel pump and fuel injectors. This motor accelerates the MAZ up to 50 km/h.
Having a strong engine, MAZ, whose load capacity was 4000 kg, could carry even the most heavy and massive loads. But there were times when 502 loaded missiles weighing 7 tons. This was facilitated by the dimensions of 7.5 meters in length, 2.7 m in width and 2,725 m in height. It is possible to carry large loads.
MAZ-502 mated to a 5-speed manual transmission and 2-speed transfer case, making it all-wheel truck of the middle class. Wheel formula 4x4 and layout – front-engined all-wheel drive, they allowed me to feel ‘king of the road”, even with the backing of a big load.
As for the suspension, it was a spring type with the front nonamortization. In fact, the car was quite hard, and the driver felt every pothole.
In the production process 502 received two modifications: MAZ-502А and MAZ-502В. A-series was equipped with a winch and were used only in military and forestry. Repeatedly with poor passability of this feature was here to help, and reinforced frame to withstand the load.
The Series – tractor MAZ.Capacity was increased from 4 tons to 7.5 tons are allowed to carry loads and used trailers MAZ-5245Б and MAZ-5245В. The series B was used mainly for transportation of army goods, In-series – for transportation of army personnel.
Till our days survived only a few copies of this outstanding technology. One is located at the plant MAZ in the museums of the plant. A 502 has been found on the former sovkhozes and kolkhozes, and then repurchased by private collectors for restorations. To date, over restored in the original MAZ-502 can fetch up to 100,000 euros. European collectors are willing to pay handsomely, if only to Soviet legend.
Some tractors can be found in landfills throughout the country. In Chernobyl there are several such instances that have been abandoned after the accident. In 2007, a group of metalloloma tried to take out one truck, but was caught by local authorities.
The Ukrainian tuning workshop “B&B” in 2012 the company introduced a tuning version of the MAZ-502. The truck was equipped with engine YAMZ-236, and an electronic injection system. Also installed alloy wheels front and rear axle have been replaced and mounted 2-row wheels. The exhaust system was made out of chrome parts, like on American tractors. The frame was cropped on the uselessness, and the ground clearance reduced by 10 cm As the car was originally a spring, the designers tuning Studio had to add in the design of dampers, which soften the suspension.
MAZ-502 – a true legend of the Soviet automobile industry. He proved to be a reliable and powerful truck that has served a whole generation. But progress spares no one, and the car was discontinued, as the older model. He replaced the legendary MAZ-500. 502 model was the first production truck the middle class, which had four-wheel drive.
