The popularity of MAZ-5336 is undeniable. The secret lies in the fact that this truck combines a comfortable 2- or 3-seater cab, in which there are seat belts, an engine heater, excellent sound insulation, ABS, rich functionality: fire and construction equipment, tankers can be installed on the truck for fuel, tanks. And thanks to the carrying capacity of 10.9 tons, you can transport almost any heavy and oversized cargo. But most often MAZ-5336 is found in road trains, because its main task was and remains "long-range" transportation.
Specifications MAZ-5336
All modifications of the MAZ-5336 have a lot of technical characteristics that significantly affect the course of the truck. For example, an improved front suspension equipped with anti-roll bars. This largely predetermines the choice of just such a machine. In addition, the MAZ-5336 has easily adjustable seats (heating is possible), as well as a steering column. The truck differs from its predecessors in a more spacious cabin, which provides two berths.
What does the car look like
Design features:
- Engine: MAZ-5336 is equipped with an eight-cylinder, V-shaped, atmospheric (in the base model) YaMZ-238 engine with a working volume of 14,866 cm3 and fuel consumption per 100 km. - 40 l (at 80 km / h).
- Transmission: double-disk clutch, hydraulic booster, 4-speed (with demultiplier - 8) manual transmission.
- The scheme of the heating system is based on the use of fuel pumps of different pressure, thanks to the all-mode regulator, it allows you to control the number of revolutions.
- The design of the brakes combines two functionally separate systems: a pneumatic foot brake system acting on the wheels and a manual brake system acting on the transmission; this design reduces the risk of total system failure.
- Suspension spring type, equipped with stabilizers and shock absorbers; discless wheels.
- Dynamics: maximum speed - 100 km / h, 50 seconds - the time sufficient to reach 60 km / h.
- The maximum gross weight is 18 tons, as part of a road train - 40 tons.
The design of the truck has a colossal working resource: the approximate mileage between each major overhaul is about 1 million km. MAZ-5336 is able to "survive" on low-quality fuel, has a relatively good cross-country ability and tolerates long heavy loads.
Chassis
Running MAZ-5336 is its strength. The suspension design was borrowed from previous models of the Belarusian manufacturer, but finalized by eliminating the existing shortcomings.
MAZ-5336 trucks have leaf spring suspension:
- The front suspension is semi-elliptical, equipped with shock absorbers and anti-roll bars.
- Rear suspension - includes a pair of main and a pair of additional springs, equipped with anti-roll bars.

Drive rear axle MAZ-5336
The front suspension has a simple, but reliable and efficient design. It consists of the following parts:
- two longitudinal springs;
- ladders;
- front bridge.
The springs are made of load-resistant steel, in cross-section their profile forms the letter "T". In this way, possible displacements are avoided. The front part of the springs is securely fixed to the truck frame, which makes it possible to move freely in the vertical direction. The rear parts of the springs are located on sliding mechanisms, through which vibrations are successfully damped.
The MAZ-5336 front suspension shock absorbers are hydraulic and are attached to the front axle using a bracket. Shock absorbers effectively dampen the vibrations of the front springs, which allows you to extend the life of the frame. Even when driving on rough roads, the shaking in the cab of the truck is practically not felt.
The rear suspension of the MAZ-5336 must withstand much greater loads, therefore it has a more complex design. The ends of the springs, as well as the front suspension, rest on supports. The central part of the springs is attached with ladders to the balancers. The balancers have a movable mount and swing on the axles.
Wheels on MAZ-5336 are 20-inch discless.
Chassis and suspension maintenance
The chassis of the MAZ-5336 truck is subjected to significant loads during operation, therefore, for the stable operation of the suspension, it requires regular and timely maintenance. When visually inspecting the front and rear suspension, special attention must be paid to nuts and other connections, as they often loosen due to vibration loads.
During maintenance of the MAZ-5336 front suspension, the condition is checked:
- ladder nuts;
- stabilizer mount;
- shock absorber mount;
- bracket fastening.
If the nuts are loose and play is observed, the fasteners should be tightened to the maximum.
The front and rear springs of the MAZ-5336 also require attention during maintenance, since they can wear out due to slipping of the plates and abrasion of the bearing parts. During the work you need:
- inspect and lubricate the spring sheets and fasteners with graphite grease (especially if a creak appears);
- check the location of the leaf springs in relation to each other;
- replace pins and bushings if wear exceeds 2 mm;
- replace the balancer bushings if they are deformed.
Shock absorbers are another element of the running gear that requires attention during the maintenance of the MAZ-5336, since it is these parts that take on the vibration energy when the flatbed truck moves. It is necessary to change shock absorbers at least once a year, and premature replacement of shock absorbers may be required if they have visual damage.
About the MAZ-5336 family
All models of the "classic" MAZ-5336 are equipped with powerful diesel engines and transmissions from the Yaroslavl Motor Plant. In the early 2000s, a small amount of MAZ-533632-321 was produced with German gearboxes and an Euro-3 compliant engine. More economical are MAZ-53362 and MAZ-53363 with diesel fuel consumption per 100 km. - about 30 liters. (at 60 km/h). MAZ-53363 is considered one of the most powerful trucks among the "classics", having a 330-horsepower engine. However, their carrying capacity is 1.7 tons less. Otherwise, the design of the "classic" MAZ does not have huge differences.

MAZ-5551
The legendary dump truck, time-tested, began to be produced in 1985. At that time, its maximum carrying capacity was only 8 tons, but several upgrades were able to correct this shortcoming. The last update took place after the onset of the 21st century. The car has got a brand new cab, under its hood there is a powerful modern engine that meets current environmental standards.
Specifications
- Engines from Cummins and YaMZ on different models have approximately the same power of 250 hp. and are capable of accelerating the vehicle up to 90 km/h
- Gearbox 9-speed from YaMZ
- Power steering
- Fuel consumption 22 l per 100 km
- Fuel tank volume 200 l
General characteristics
- The maximum load capacity is 10 tons for all modifications sold since 1998
- Gross weight with loading does not exceed 16.5 tons
- The height of the car is 2.925 m, so you should be careful under the three-meter bridges
- Ground clearance does not exceed 28 cm
MAZ-5551 is a dump truck, so the convenience of unloading plays an important role for it. Cabin rises 47 degrees in 15 seconds when fully loaded. It takes about 10 seconds to return to the starting position.
Cabin
Updated has comfortable seats. On the driver's side, the seat is sprung, but that's all the comfort you should count on. As if wanting to emphasize that the MAZ-5551 was created exclusively for work, the designers did not even include a radio tape recorder in the basic package.
This Spartan style is slightly offset by a convenient folding cockpit mechanism, which takes into account and corrects all the shortcomings of early modifications. Now the cabin leans back smoothly, provides free access to all other elements, and the location of the folding mechanism under the radiator grille serves as an excellent security system, because it will be impossible to raise the cab without opening the grille.
Despite the presence of several shortcomings, the MAZ-5551 is still considered one of the best solutions of the plant, since it has been performing its functions regularly for decades, regardless of the vagaries of the weather and the intensity of operation.
How to perform tuning MAZ-5336
Among MAZs, especially those used for "long-range" transportation, one can hardly find two identical copies. Each driver comes up with his own unique style. What allows tuning the cabin MAZ-5336:
- Installing a high roof, spoilers, exterior trim.
- Change of standard interior decoration due to decoration with metal, leather, wooden elements.
- Improving the information content of the dashboard, lighting using LEDs.
In addition to manipulations with electric wiring, they also perform other work related to ensuring comfort: installing an autonomous air conditioner, heating windows, and independently improving the suspension. Tuning samples can be seen in numerous photos.
Steering
The steering of the MAZ-5336 is comfortable and convenient. The steering column is adjustable in height and reach, so the driver of any build will be able to customize it for themselves. The MAZ-5336 steering system includes power steering. The hydraulic booster does not impair handling and helps to reduce the load on the driver. In general, drivers speak positively about the power steering and steering of the MAZ-5336, recognizing its design as successful.
The steering column MAZ-5336 is configured according to a number of parameters
The disadvantages of steering include the appearance of fairly strong backlash. To eliminate them, the system needs periodic adjustment of the rack, screw bearings and gearing. The process is complicated by the need to dismantle the structural unit.
The power steering MAZ-5336 consists of a distributor and a power cylinder. They come assembled and change if necessary as a single unit. The constituent elements of the power steering hydraulic system are:
- NSh-10 pump (mounted on a truck engine);
- reservoir for hydraulic fluid;
- pipeline system.
To prevent dirt and dust from entering the hydraulics, rubber seals are used at the joints.
The cavity of the power cylinder of the MAZ-5336 hydraulic booster is divided into two parts:
- piston,
- over-piston.
The cavities of the power cylinder are connected to the channels in the distributor housing using pipelines.
The principle of operation of the power steering on the MAZ-5336 is as follows:
- when the truck engine is running, the hydraulic system pump supplies oil to the hydraulic booster;
- depending on the direction of movement of the truck, hydraulic oil is returned to the tank or is supplied to one of the cavities of the power cylinder;
- the oil-free cavity is connected through the drain line to the tank;
- if the truck moves in a straight line, oil is supplied through the pressure hose and then through the drain line back to the tank;
- if the truck turns, then when the steering wheel is turned, hydraulic oil is supplied to one of the cavities of the power cylinder, exerting pressure on the tie rod associated with it;
- If you stop turning the steering wheel, the oil begins to drain back into the reservoir.
The power steering on the MAZ-5336 is highly sensitive, making it easier to control a flatbed truck even at maximum load. In general, the steering mechanism is quite reliable, although it requires regular maintenance - in particular, inspection for power steering leaks and tightening the bolts to eliminate steering column play.
Purchase of MAZ-5336
If necessary, finding and buying a MAZ-5336 is not a problem. An analysis of the prices of used cars that can be bought at Avito showed that the average minimum cost is 200 thousand rubles. The average ceiling cost of MAZ-5336 is 500 thousand rubles. The price is predetermined by the configuration, year of manufacture and condition of the car. A brand new MAZ-5336 will cost 1.5-2 million rubles. When buying, as a worthy alternative, you can consider the more modern MAZ-5340 of 2002, which is the receiver of the MAZ-5336 with a lot of improvements. The average price for this model is 1.8-2 million rubles.
Cabin tuning option
Gear shift
Gearbox on the MAZ-5336 with engines of the YaMZ-238 family, also of the Yaroslavl assembly - YaMZ-2381. This is a four-speed manual transmission. To increase the number of speeds, a demultiplier is installed on the transmission. Thus, the manual transmission has 8 speeds. 7 gears are equipped with a synchronizer, it is not only in reverse gear.
Given that the 1st gear gears do not have a synchronizer, switching to 1st gear can only be done after a significant reduction in speed.
YaMZ-2381 transmission on a MAZ-5336 truck
The clutch on most YaMZ-2381 gearboxes is double-disk, but there are also single-disk modifications. Also, a manual gearbox is equipped with a hydraulic booster.
A feature of the gearbox on the MAZ-5336 is that the transmission is quite far removed from the driver. This required the implementation of remote control of the checkpoint. The transmission remote drive consists of:
- gearshift mechanism (located directly on the gearbox);
- levers (they are mounted in the cab and connected to the gearshift lever).
To prevent the simultaneous inclusion of two gears, a lock is provided on the MAZ-5336 transmission. When one of the rods moves, it locks the rest in a neutral position. This mechanism is implemented with the help of balls that come out of their recess and enter the position of the rod, preventing it from getting into its working position.
The MAZ-5336 gearshift diagram is shown below.
