The appearance of MAZ-6303, due to its conservative appearance, is not too impressive. The model compensates for this disadvantage with excellent technical indicators... It is no coincidence that the car has long been called the best "board ranged combat". The multifunctional transport is positioned as the most powerful truck for working at long and medium distances.

Reviews of MAZ-6303 were extremely positive. It is they who, probably, became the reason that the Minsk Automobile Plant released a whole series of various modifications of the model with the indices A5-320, A5-321, A5-326, A5-329 and A5-335. Additionally, reinforced versions of the car were produced: A8-320, A8-324 and A8-325. On the basis of the standard MAZ-6303 chassis, the MAZ-630168 model with a six-by-four wheel arrangement and the MAZ-6317 all-wheel drive vehicle is also produced.

The car is used to transport goods separately or as part of a road train. The model meets the TIR requirements. The improved power plant installed on the MAZ-6303 allows it to be used in European countries.

The front suspension of the truck is spring, the rear is spring-balanced. The large and spacious cab offers maximum comfort when traveling long distances. This element is equipped with one berth.

The truck is equipped with a rather large platform with an area of \u200b\u200b18.6 "squares", which is covered with an awning. The body holds up to 43.5 cubic meters of cargo. Loading and unloading is done through the rear doors.

The car was never able to completely abandon the Soviet past. The old design and minimalism do not make you feel as comfortable as possible. For its size, the truck is quite dynamic. It has excellent visibility to the back and front as well as to the sides. This is especially useful when driving in city traffic. The almost complete absence of noise and vibration in the cabin adds positive emotions. The passenger seat will also delight. The manufacturer made it on air suspension, which is extremely rare on dump trucks. In MAZ-6303, the passenger is also in a privileged position.

You don't have to spend a lot of effort to shift gears, turn the steering wheel or press the pedal. This is especially important on long journeys.

MAZ-630, which has a very modest design, takes on a completely different one. The model has excellent technical specifications and low cost, which is especially appreciated by Russian buyers.

Specifications

Overall dimensions of the MAZ-6303 car:

• length - 10230 mm;
• height - 4000 mm;
• width - 2500 mm;
• wheelbase - 3810 mm.

Carrying capacity of the machine is 12,700 kg with a technically permissible weight of 24,700 kg. On rear axle the truck has a load of 18,000 kg, the front load - 6,700 kg. As part of a road train, the gross weight increases to 44,000 kg.

To increase grip with the road surface, 11.00R20 tires are installed on the equipment. With a speed limiter, the maximum acceleration of MAZ-6303 is 85 km / h, without it - 100 km / h.

Fuel consumption per 100 km MAZ 6303

The car's fuel tank holds 350 liters of fuel. The car consumes about 27.5 liters of fuel per 100 kilometers. At the same time, on the highway, the figure drops to 24.3 l / 100 km, and in urban conditions it increases to 40 l / 100 km.

Engine

MAZ-6303 is equipped with a diesel 4-stroke 8-cylinder V-shaped unit of the YMZ-6563.10 model (manufacturer - Yaroslavl Motor Plant). There are two valves per cylinder. The power plant complies with Euro-3 standards. The unit is located longitudinally and in front.

Motor parameters:

• working volume - 11.15 l;
• rated power - 184 (250) kW (hp);
• torque - 1225 Nm;
• cylinder diameter - 130 mm.

Device

All versions of MAZ-6303 are equipped with an old-format cab, available in two versions:

1. daytime small without sleeping bag;
2. large, equipped with two berths.

The manufacturer emphasizes that the cab sound insulation has been improved in comparison with its predecessors. At the same time, the cabin does not differ much from analogues of leading brands in this parameter. A sprung passenger seat is also a rarity, despite the fact that the Minsk Automobile Plant originally declared it as a basic parameter. Seat belts appeared on all modifications.

The truck is equipped with an 8-speed mechanical box gears of the YMZ-238A model.

The complete set of the standard version of MAZ-6303 includes:

• electropneumatic outlets for the trailer;
• spoiler;
• rear protective device;
• an engine heater that helps to start the unit in the cold season;
• driver's sprung seat;
• seat belts;
• cab sound insulation.

Wide range optionally available additional equipment (special heating).

The disadvantages of the model include the not very convenient location of the stove heater tap. It is located in the same place where it appeared half a century ago. To open it, the driver will have to raise the cab. Among other disadvantages, one should highlight the inconvenient location of additional equipment (keys, jack, etc.) and the unsuccessful fastening of the air filter cover, which, instead of latches, received studs with nuts. Despite the shortcomings, MAZ-6303 meets the TIR requirements and is successfully operated in transport companies.

Particularly popular among special vehicles based on MAZ-6303 is a log truck with a CMU, which has a carrying capacity of 13,200 kg. It is traditionally equipped with large cockpit with two berths.

The price of a new and used MAZ 6303

MAZ-6303 is one of budget models... So, the version with a wheel arrangement of six to four is offered by the plant for 1.38-1.58 million rubles (excluding VAT). Modifications with a wheel arrangement of eight to four and six to six will cost more.

The cost of a used version of MAZ-6303 (2007-2008 with a mileage of 140-150 thousand km) will be 600-700 thousand rubles.

Renting a truck will cost from 1100 rubles per hour of work.

Analogs

The analogues of the MAZ-6303 model are hyundai cars HD 78, ZIL-43336 and MAZ-43714.

MAZ 6303 is one of the most powerful models of the Minsk Automobile Plant. The truck is distinguished by a rather conservative appearance, which is complemented by excellent operational and specifications... A multifunctional vehicle can move loads with a total weight of up to 14,000 kg over long and medium distances, regardless of the climatic region.

Due to its high performance and unpretentiousness, MAZ 6303 received many positive reviews, having spawned a large family of trucks with various superstructures (log truck, tow truck, car lift, water carrier, timber carrier, car lift and others).

The owners of MAZ 6303 note its endurance, ergonomics and low cost, rightfully referring it to the number of the most successful transport vehicles.

Model history and purpose

MAZ 6303 has a rich history, although the production of the model began only in the 1990s. The car became the base for the 3-axle product category of the Minsk Automobile Plant. On the basis of this machine, many different modifications subsequently appeared.

The development of the car began at a not very favorable time for the plant. After the collapse of the USSR, the enterprise began to experience a serious shortage of funds, which competitors tried to take advantage of, which actively entered the segment of heavy trucks. The Minsk Automobile Plant needed a “fresh” product that customers would like. As a result, the development of a new model began, and soon MAZ 6303 was presented to the public. The car turned out to be very successful, becoming the ancestor of a huge family.

On the basis of MAZ 6303, various trucks were subsequently manufactured. The family includes:

• MAZ 630168 with a six-by-two wheel arrangement;
• MAZ 6317 with a six-by-six wheel arrangement;
• timber carrier MAZ 630326;
• a large tractor based on MAZ 6303, capable of transporting up to 67,000 kg of cargo as part of a road train.

Later, other versions appeared. Additionally, special modifications were made for harsh operating conditions.

The MAZ 6303 chassis is used to install various add-ons, therefore the scope of the model is very wide. The most widespread are the standard versions of the car, which are used to transport large cargo over long distances. Manipulators based on MAZ 6303 are used in industry, construction, mining and other areas, at the same time serving as a carrier and a loader. Timber trucks MAZ 630326 are used in agriculture, forestry and private companies. There are other versions of the vehicle.

Specifications

The powerful MAZ 6303 truck is a combination of high efficiency and productivity. The solid dimensions do not prevent the car from covering long distances at a decent speed. With a limiter, the truck accelerates to 85 km / h, without it - up to 100 km / h. For movement on the highway, this speed can be called optimal. Also MAZ 6303 stands out for its low fuel consumption - about 25 l / 100 km. In urban conditions, the indicator increases to 40 l / 100 km. The fuel tank of the machine is 350 liters.

Vehicle dimensions:

• length, including the cab and body - 10230 mm;
• width with sides - 2570 mm;
• height - 4000 mm;
• the length of the cargo compartment - 7560 mm;
• cargo compartment width - 2430 mm;
• cargo compartment height - 2250 mm;
• distance from bumper to center weight - 3865 mm;
• front wheel track - 2032 mm;
• rear wheel track - 2032 mm.

MAZ 6303 has a wheel arrangement of six and four and a carrying capacity of 13100 kg.

Other characteristics of the model:

• permissible total weight as part of a road train - 44,000 kg;
• permissible gross vehicle weight - 24,500 kg;
• curb weight - 11,400 kg;
• platform area - 18.14 sq.m.

To improve traction, the vehicle is equipped with 11.00R20 tires.

Engine

All versions of MAZ 6303 are equipped with one version of the power plant - a 4-stroke 8-cylinder diesel engine produced by the Yaroslavl Motor Plant. Paired with a powerful transmission, the motor guarantees maximum performance with relatively low energy consumption. The unit is distinguished by a large margin of safety. With timely and proper maintenance, it can serve for more than a dozen years without the need for major repairs.

There are 2 valves per cylinder of the unit. In the car, the engine is installed longitudinally.

Motor characteristics:

• working volume - 11.15 l;
• rated power - 184 (250) kW (hp);
• maximum torque - 1225 Nm.

The power plant meets the requirements of the Euro-3 standard. In all versions, the engine is equipped with a special heater that simplifies starting at subzero temperatures. The engine is liquid cooled.

Device

The MAZ 6303 car uses a standard scheme for the products of the Minsk Automobile Plant. The supporting structure for the body, suspension and engine is a strong frame made of durable materials. Even difficult conditions she is not afraid of exploitation. The most vulnerable elements here are cross members and linings, but it will not be difficult to change them.

The middle axle of the car is distinguished by a complex design, since it is a walk-through between the main nodes. It is with him that problems usually arise. When a lot of noise appears, we can talk about significant wear of the gears, which will have to be changed quite often. Also, an increased sound during operation may be due to failure of tapered bearings. Oily brake pads will talk about the need to replace the hub cuffs. It is better to solve such a malfunction as soon as possible, since it poses a serious danger to the driver.

Problematic electro-pneumatic valves are also subject to urgent replacement. Their malfunction causes a malfunction of the differential lock.

MAZ 6303 is equipped with an 8-speed manual transmission of the model "YAMZ-238" or "YMZ-239" (manufacturer - Yaroslavl Motor Plant). There are no fundamental differences between them. The gearbox itself is made very high quality, the speed is switched on it simply and without difficulty.

For all modifications of MAZ 6303, an old-style cab is used, available in two versions:

• small (day version without berth);
• large with 2 sleeping places.

The cab has good sound insulation, which is especially emphasized by the manufacturer. However, for most European cars, noise protection is a prerequisite, so this is not even mentioned. In addition, in this parameter, MAZ 6303 loses a little to foreign competitors. In some versions of the truck, a sprung passenger seat was installed. However, more often only the driver enjoyed such comfort. Seat belts were present on all seats. The cab itself has excellent visibility in all directions. Vibration inside is practically not felt, which makes the trip more pleasant. Along the edges of the cab there are 2 handles, designed to climb the bumper and reach the glass if necessary.

The ergonomics in the cab are not the best. So, it is possible to find a stove heater tap only after a long search. It is noteworthy that for the entire time of release, it has not changed its location. MAZ 6303 also has a much more significant drawback. Quite often, the model has a runout of the front left wheel. Minor shortcomings are manifested in the inconvenient location of the equipment (jack and other) and in the fastening of the filter cover, which is fixed instead of latches with studs and nuts. However, this does not prevent the truck from being TIR compliant and operated by many transport companies.

Among other shortcomings of the model, the low level of driver comfort should be highlighted. The cab has not been modernized since the car was premiered.

AT basic configuration MAZ 6303 is equipped with:

• electro-pneumatic leads to the trailer;
• soundproofed cab;
• motor heater;
• sprung driver's seat;
• backlash-free coupling;
• seat belts;
• protective device at the back; spoiler.

Price of new and used MAZ 6303

The powerful truck has many positive reviews and is in demand all over the world due to its excellent technical characteristics. One of the main advantages of MAZ 6303 is its low cost, which makes it very affordable. From the factory, a basic car can be purchased at a price of 1.9 million rubles. For such a powerful carrier, this is a huge advantage that allows you to quickly recoup your costs. Also, the costs of maintenance and repairs will be small, which makes used versions of MAZ 6303 very popular. The cost of modifications in 2005-2007 is 600,000-1000000 rubles, in 2012-2014 - 1.2-2 million rubles.

Analogs

The analogs of the MAZ 6303 car include russian trucks KamAZ 53215 and KamAZ 4355.

MAZ-6303 is a Belarusian-made truck developed in the mid-1960s. Sales of the car began in 1965, but every year the car was further improved. Changes to the design increased reliability and comfort, but maintainability was at a high level, regardless of the introduction of more modern modifications. In 1974 came out modernized version with diesel engine YaMZ-238E power 270 horse power... The car received a wide variety of modifications, including a large tractor unit as part of a road train, as well as a timber truck. The maximum carrying capacity was 67 tons.

MAZ-6303 owner reviews

• Alexander, Petrozavodsk. The car was purchased two years ago. Model MAZ-6303 in the modification of a cement truck. The car was produced in 2008, with a YaMZ-238 engine and a mechanical eight-speed gearbox. Short splitter transmission. Now I work in Siberia, MAZ is ideal for frosty conditions. The truck is generally not bad, but only with respect. With it, you can earn good money, and at the same time spend minimal funds on maintenance. The main thing is not to overload the car. Power unit - momentary and high-torque, pulls in a wide range of revolutions - both on a straight road and on slopes. At subzero temperatures, starting the engine is not a problem - it starts almost from half a turn. I was glad that the engine is unpretentious to the quality of diesel fuel, unlike foreign cars. Steering uninformative, the steering wheel is frankly empty and sometimes you have to guess where the wheels are turned. But in cramped conditions it is convenient to drive, because the steering wheel weighs practically nothing. The steering wheel is very light, and the truck itself is heavy and clumsy. Immediately after the purchase, I installed tubeless on the front axle. The chassis amazes with its endurance and energy intensity. Suspension stiffness is felt only on bad roads. Naturally, it is not complete without replacing consumables. Instead of native springs, I installed KAMAZ springs, from model 6520. They are more reliable. I will especially note the reliability frame structure, which is still intact, I have never digested it. Sitting comfortably in the cockpit is quite acceptable for a workhorse. But at the end of the working day, the back starts to get tired. I recently installed a new seat with an anatomically shaped backrest and improved lateral support - it's more comfortable and the back doesn't hurt so much. Steering wheel At first I thought it was too big, but after a while I got used to it. I have a modification with a full-fledged bed, which I use often, as I do not want to spend money on hotels. The car did not have an autonomous heater, I installed it myself. The stove heats up incomparably - so well that no frost is terrible. Of course, serious breakdowns happen at times. This is not surprising, since our technique has always required increased attention. The main thing is to fix these problems in time, and then everything will be normal. The car consumes a maximum of 35 liters per 100 km, and it is loaded.
• Sergey, Irkutsk. I drive a supported MAZ-6303 1996 release. I have a version with onboard body with the CMU. I bought it in 2014. Then they gave me new imported tires and an additional trailer, which is doubly pleasant. After distillation, I immediately changed consumables - oil, filters and other details for little things. The car was fully operational, but initially I did not like the location of the gas tank and I moved it to another location. The car is equipped with a KAMAZ gearbox, but I have not yet come to an unambiguous conclusion whether it is good or bad. The transmission works reliably and without interruption. All speeds can be switched with little effort. Well, except that second gear requires a little more effort. The car was equipped according to the basic principle, but this had a favorable effect on the cost. The salon is not equipped as it should be from the factory. Not only is there no sleeping bag, but also the right seat. Over time, I installed both the seat and the sleeping bag, and even made complete noise isolation so that there was less noise and vibration. I re-flashed the walls and ceiling, and laid linoleum on the floor - the usual one, like in an apartment. As a result, it became more pleasant in the car, a home environment appeared. I completely renovated the interior, but the outside was the most defective. The body quickly rusts and rots. Redecoration was needed, and timely. I had to putty and repaint. When the first voyage took place, it was March. I was given expanded clay blocks for transportation. I took 20 at once 20 pallets, which is me - I needed less. Fortunately, I somehow drove it, since then I take less. When I was driving back, the engine suddenly stopped starting. The first inspection revealed a starter failure. There was nothing left to go home. I called a tow truck, arrived and replaced the starter. Everything works now. The second trip did not bring such surprises. Of the breakdowns, there was only one - the bursting of the hydraulic system of the rear supports. I was on the road then, somehow corrected it. Recently there was a flight to the forest - the road was so limp that I almost drowned the car. Still, the permeability is not very good. Unfortunately, we had to unload everything to get out of the mud trap. The car consumes 30-35 liters per 100 km.
• Oleg, Tomsk. A reliable and durable car that has both advantages and some disadvantages. For example, these are poor reliability and passability, low-quality spare parts and weak engine... On the other hand, the machine is easy to repair and does not require high costs. Excellent visibility and effective brakes. The cabin is spacious and comfortable, but the firm seat makes you finish your day as soon as possible - your back gets very tired and then hurts. I have a MAZ-6303 for the transportation of bulky goods. Standard version 1993, an additional trailer can be connected to it. The machine is equipped with a YaMZ diesel engine and an 8-speed manual gearbox. The transmission runs smoothly, as does the engine. If there are flaws in the suspension and in the chassis as a whole, if you drive on bad roads. Once again I am convinced that MAZ is less adapted for off-road. It is necessary to travel with a partner in order to get tired less - you can relax in a sleeping place. You can't sit on such a hard seat for a long time. The car consumes a maximum of 35 liters per 100 km, and the engine is undemanding to the quality of fuel.
• Andrey, St. Petersburg. I have repeatedly had to work on trucks of various brands, but mostly they were MAZs and KAMAZs. I mainly work in forest conditions, on light off-road, so to speak. From my own experience, I will say that MAZ-6303 is ideal for rural conditions. In terms of reliability, the car is not worse than KAMAZ, but it is certainly cheaper to maintain. I have a 1995 modification with a 400 hp diesel engine. The turbine motor provides excellent dynamics even when laden. The machine confidently pulls uphill and uphill. Only annoys with noise and vibrations. But on the other hand, the more noise and rattling, the better it is felt in what rev range the engine is operating. In other words, it makes the car feel better. For example, I have long been accustomed to Mazik, to its archaic handling and numerous minor breakdowns. Sometimes it feels like a car will last forever with regular maintenance. MAZ-6303 never broke down on a large scale, and if necessary, it can be repaired even in the field - I always have all the tools in stock. Of course, at times I have to dig into fuel oil and glands, and I try to fix everything with my own hands - it's cheaper. The car is sturdy and durable, adapted to our conditions. Inexpensive parts can be found in second-hand condition and most parts are in stock. The car consumes 40 liters per 100 km when loaded. So much is obtained off-road, and much less in the city.
• Maxim, Saratov. I am the owner of MAZ-6303 1996, with a powerful diesel engine. Before this truck, I drove a ZIL, so the experience of communicating with big trucks I already had it. The previous owner of Mazik installed a CMU, he also had an additional trailer. The owner was preparing the car for work, but there was not enough money to restore it. So I decided to finish it. Plus, I bought a car at a big discount. In general, I remade the truck as it should be, but spent two whole years on it. All this time I was refining the car, identifying flaws and then eliminating them. On the one hand, this is a very painstaking and tedious business, but on the other hand, it’s even somehow interesting, if only there was money, as they say. I digested the cabin, went through the gearbox and divider, installed a new middle gearbox, changed two hubs, and left the CMU intact, only I had to remake the finger on the CMU. I installed new fuel equipment and some other details. The car was updated almost from scratch, because it was still necessary to repaint the cabin, install sound insulation in the cabin. Cracked windshield also a replacement. I have a 9.9 liter diesel version with 330 horsepower. Motor with mechanical transmission and rear wheel drive... The car is 1996, the current mileage is 400 thousand kilometers. Fuel consumption in the range of 25-35 liters, depending on the quality of the roads and the degree of congestion.
• Ivan, Chelyabinsk. I have in operation a heavy truck MAZ-6303 A8-328 with an increased carrying capacity of 15 tons. Diesel power 330 horsepower, car produced in 1998. The car has decent dynamics and economy. For example, at 60 km / h, you can keep within 24 liters, and this is in a loaded state. At 80 km / h, it already comes out under 30 liters. The car is equipped with an all-metal cab, which constantly rusts and corrodes, especially in the area of \u200b\u200bthe door sills. They need to be tinted regularly so that there is no total defeat. There is plenty of room inside and visibility is excellent thanks to the slim A-pillars and large rear-view mirrors. There is one berth, which is wide enough for a large driver. The steering mechanism does not present surprises, you just need to get used to it. The steering wheel is too empty and wadded, the connection with the wheels is almost not felt. The front panel is made of ultra-cheap plastic, which constantly rattles, creaks and vibrates. Unfortunately, the developers decided to save on the quality of the parts. I even doubt that they are capable of doing something better, if they had good components. And yet, Belarusian engineers have created a noteworthy product that is worth the money spent. Despite the shortcomings associated with discomfort, reliability and passability, I liked the MAZ-6303, as well as our colleagues at work. It has a high carrying capacity, and in terms of maintainability, it even outperforms KamAZ. Dynamics pleased maximum speed is 90-100 km / h.

The successful model, which is produced under the name MAZ 6303 from the Minsk Automobile Plant, immediately found its admirers. Outwardly, the truck looks rather conservative, but this does not prevent it from having excellent technical characteristics.

Price

To buy a MAZ 6303, you will have to pay 600,000 - 1,000,000 rubles for a 2005-2007 model. For newer copies (2012-2014 onwards), you will have to spend 1.2 - 2 million rubles.

The power plant YaMZ-6584.10 of the Yaroslavl plant has fuel equipment systems, there is fuel pumpthat works under high pressure. The engine has eight cylinders, sixteen valves. Power up to 250 HP Complies with the ecological class "Euro - 3". The cylinders have a volume of 11.6 liters.

The torque impulse from the power plant is transferred to the wheels using a dry disc clutch, the drives have a pneumatic booster.

Suspension, bridges

Technical characteristics allow the car to move without much difficulty on dirt roads and even off-road.

On all models, it is present in which there are semi-elliptical springs. Moreover, the suspensions also contain two dual-use hydraulic shock absorbers. A special stabilizing device is used for transverse additional fasteners.

The rear axles of the heavy truck have leaf spring suspension... The middle spring block is attached to the balance bar, which interacts with the axle. And the whole unit is attached to the main frame.

This balancer functions on an axle that fits into the holder. Another balancer is fixed to the frame with brakes. In the exhaust system, there are special valves for the compression auxiliary brake.

As for the braking system, it is present on all wheels. It should also be noted that the truck is equipped with aBS system and a separate drive.

The history of the creation of MAZ 6303 in Minsk car factory began in the mid-sixties of the last century. The need for transportation a large number cargo for the national economy of the Soviet Union has always existed, but it was at this time that there was a catastrophic lack of heavy equipment. A three-axle tractor was supposed to appear, capable of effectively carrying out transportation both on general-purpose highways (the quality of which always left much to be desired), and in unpaved and country roads... Belarusian automakers tested the first developments in the creation of such a car on models such as MAZ-516 with a rear axle, the MAZ-512 and MAZ-515 truck tractors, as well as the MAZ-514 onboard vehicle. MAZ 6303 had many predecessors, and their fate was different. Some models were released only in experimental batches and did not enter mass production, others, for various reasons, were produced for a very short time. Be that as it may, by the beginning of the 90s of the last century, a powerful onboard three-axle with a 6X4 wheel arrangement saw the light, which was a fresh decision for MAZs. The opinions of experts about this machine still differ. Some believe that in his appearance and the designs never got rid of the "Soviet" past. According to others, MAZ 6303 is one of the best domestic long-range aircraft. Nevertheless, the design of the car turned out to be so successful that almost all subsequent MAZ three-axle models have some kind of technical connection with it. On the basis of MAZ 6303, heavy-duty vehicles with 6X2 and 6X6 wheel arrangements have also been developed.

Appointment

Initially, MAZ 6303 was created under European requirements, which determined its further success. Working at medium and long distances is the main specialization of the multifunctional chassis truck. If the car was created for European roads in accordance with the requirements of international transit transportations TIR, then the safety margin allows it to be successfully used in heavy road conditions... Initially, MAZ 6303 was designed as a mainline tractor for operation both independently and as part of a road train. Later, on its basis, timber trucks, truck cranes and car lifts, fuel tankers and tank trucks, tow trucks and other equipment were created. Depending on the superstructure, MAZ 5303 is used in almost all spheres of the national economy, from oil and gas production to agriculture. Even the basic configurations of the car perform excellently both in northern latitudes and in regions with hot climates. There are machines specially adapted for special working conditions.

Modifications

MAZ 6303 can be considered as a universal platform on which, depending on the customer's requirements, the necessary equipment is installed. Cargo platforms can be open side, curtain or awning type. Tipper platforms, logs and cranes with a lifting capacity of up to 25 tons can also be installed. Among the main modifications of MAZ 6303, which are the most widespread, one can note:

• MAZ-630326 - a truck-tractor or a log truck for transportation of assortment from 2 to 6 meters long as part of a road train. The total mass of the road train can reach 48,000 kg. Wheel formula 6X4;
• MAZ-630168 - freight car with wheel arrangement 6X2, designed for the carriage of goods in the TIR transit system as part of a road train with a total weight of up to 44,000 kg. TIR compliant.
• MAZ-6317 is an 11-ton cargo all-terrain vehicle with a 6X6 wheel arrangement. Variable pressure wide all-terrain tires with large ground clearance, allows the car to transport goods over rough terrain as part of a road train with a gross weight of up to 55 tons. It is often used as an aerodrome towing vehicle for aircraft towing. It is widely used both in the military field and in civilian industries.

Currently, several modifications of platforms with a carrying capacity of 14.5 to 19.5 tons with a wheel arrangement of 6X4 are produced. The chassis is equipped as traditional yaMZ enginesand Deutz power plants. Chassis MAZ 6303A5-348 (-349, 351, 352) are intended for installation of cranes, excavators and concrete mixers. MAZ 6303A5-348 (-349) configurations are equipped with a central power take-off gearbox (TsROM).

Features and operation

Despite the fact that the MAZ 6303 cab was developed for a long time and is inferior in terms of design to many Western competitors, on the whole it turned out to be successful. Specialists note low noise and vibration levels, good visibility from all sides. Not only the driver's seat has air suspension, but also the passenger's seat. In conditions of low temperatures, a comfortable stay in the cab is provided by the main and additional heating system. However, the location of the heater tap under the cab does not add comfort in severe frosts. Drivers also complain about the air filter cover on studs with nuts (instead of latches), which makes it difficult to quickly replace the filter element. Complaints are often expressed about the location of the hydraulic lift of the cab in a place unprotected from dirt. However, despite minor flaws, reviews about the car among motorists are mostly positive. In the basic configuration MAZ 6303 is equipped with:

• Spoiler and rear guard;
• Backlash-free coupling;
• Electro-pneumatic leads to the trailer;
• Safety belts;
• Engine preheater;
• ABS system.

The engines of the Yaroslavl Mechanical Plant 238 series installed on MAZ 6303 do not cause any special complaints. Depending on the intended purpose, power plants with a capacity of 170 to 400 hp can be installed. In general, the car is reliable, easy to maintain and repair, and is familiar to domestic drivers. There are no problems with the availability of consumables and spare parts, the price of which is much lower than for the European and American analogues of MAZ 6303.
