Two-axle truck tractors MAZ-5440V9, 5440V5, 5440V3, 5440V7 are perfect for transporting goods as part of a train on highways, as the owners say. MAZ-5440 allows the load specified in the technical specifications of a particular brand of machine. Truck tractors work with semi-trailers that are equipped with attachments with dimensions in accordance with GOST 12105, a class H50 kingpin in accordance with GOST 50023, electrical detachable circuits in accordance with GOST 9200, power from an anti-lock system, pneumatic brake actuator in accordance with the requirements of UNECE 13.

MAZ-5440

MAZ in 2005, leaving the assembly line, became a rival to KamAZ 4308 and won the championship, proving to be the best truck this year.

Even tough Europe with its demands accepted this truck tractor with open arms, and its entire family began to be used for international transportation. The design of the cabin and its appearance have become quite modern.

Increased cabin height for MAZ-5440. Owner reviews say that aerodynamics have become better. Now, looking from afar at those riding in a slendercar column, it becomes difficult to distinguish their cabs from modern European designs. Instead of glass, plastic is used, which significantly reduces the weight of the MAZ tractor 5440. Owner reviews indicate an excellent direct view through the front panoramic glass. The use of two large side mirrors contributes to a better view of the entire area around the machine.

The designers tried to provide drivers on long trips with the highest degree of comfort due to the adjustable air suspension of the driver's seat in the MAZ-5440 A9. Owner reviews say that the cabin has an excellent exit-entrance. Exterior painting of the cabin is carried out in various colors, sometimes unpainted plastic is used for decoration. The new steering column and dashboard distinguishes the car from the old models very favorably. The cabin of the car is provided for a double, it has two or one bed in the form of shelves. This comfort, coupled with automatic temperature controls in the cab, made driving long distances less grueling than owner reviews say. MAZ-5440 designers brought to European standards.

Car engines

All of the above brands of trucks are equipped with engines from the Yaroslavl Motor Plant, which is abbreviated as YaMZ. These products, leaving the territory of the enterprise, comply with environmental standards of European standards.

Climatic modification of cars is of two types:

• U1 operate in the domestic market andare exported to countries with moderate climatic conditions;
• T1's are exported to tropical weather conditions.

In some cases, for operation in very difficult conditions, motors with a lower cost (YaMZ-75.11.10) with a capacity of 400 horsepower and LiAZ with the same indicator of 375-440 are installed on cars. MAZ-5440 A5 can travel long distances without repair. Owner reviews say this is possible if you follow simple safety instructions.

Vehicle specifications

Parameters comply with international standards:

• engine capacity 11960 cm3 provided;
• motor power 370 horsepower;
• international environmental standard EURO I;
• torque 152 Nm;
• 6x4 transmission drive;
• number of gears 16;
• gearbox model ZF16 S 151;
• spring suspension front and pneumatic rear;
• 500L fuel tank;
• maximum travel speed 120 km/h;
• a car consumes 25 liters of fuel per 100 km.

Car cabin

It is located above the engine, made of solid metal, in some places the structure is welded, it has two places, if necessary it tips forward.

If it is necessary to transport a third person, then the middle seat on the sleeping shelf of the MAZ-5440 car is used. Owner reviews speak of a convenient lift-up panel that providesaccess to automotive units located behind the front panel. When it is raised, it rests securely on air springs, and when lowered, it is secured with locks.

The space under the sleeping bag is used on a trip to place small necessary items, a heating fireplace or a small refrigerator is installed there. The side wardrobes are very conveniently located, as the owners' reviews say. MAZ-5440 with a Renault engine has an upper sleeping bag, which is located at a comfortable slope while driving.

Transmission

During the operation of a truck-tractor, a hydraulic clutch release drive with a pneumatic booster is used. Clutch free travel and full travel are adjusted using the pedal.

Full adjustment to 125 mm of travel is done before free adjustment with two stop bolts of 4 and 8 diameters, while the locknuts are loosened - they are tightened after the adjustment is completed.

Operation and preparation of the gearbox

Before starting work, they check the setting of the box control system to other devices of the machine, as the owners' reviews say. MAZ-5440 is checked before work for compliance:

• pneumatic system to the shift valve located in the lever and the pressure reducing valve;
• power supply of the automatic blocking system ASBP electrical circuit of the machine;
• power supply for the low gear switch lamp in the demultiplier and the control lamprear travel electrical system of the car;
• drive box and gear shift lever.

To check the oil level in the gearbox, you need to unscrew the plug on the right side of the crankcase, and then place it in the hole until it stops with the pointer. The oil level should match the upper mark on the pointer, as the owners say. MAZ-5440 with a Mercedes engine performs gear shifting in a demultiplier by changing the ranges controlled on the lever handle. You should test the operation of the ASBP, for which you need to check the burning of the lamp when the low gear is on.

Starting aid

The system includes a heating element on the intake manifold and a relay device that operates from the signals of the electronic unit and is located on the engine. This system starts a cold engine at low air temperatures, according to owner reviews. MAZ-5440 automatically turns on the device when the switch-lock is activated.

In addition to heating the air, this system raises the temperature of the fuel in the fine filters, which reduces the risk of clogging of the filters with paraffin formed in the cold. Heating starts automatically after the starter starts.

Idle control

With this function, a cold engine warms up faster in optimal conditions before starting the car from a stop. You can manually set an increased speed for power selection, this is done on the presentcar. Feedback from the owners of the MAZ-5440 and a review of the answers in the forum indicate that the regulation is carried out in steps of 50 minutes each time the switch is pressed.

Speed limit

To do this, there is a system configuration that allows you to automatically adjust the maximum speed. During movement, the speed can also be reduced by applying the motor brake. The regulator of this device is located on the floor at the driver's foot, and you can constantly reduce the speed of movement while the switch is pressed in the MAZ-5440 B5 car.

Owner reviews say that the panel is attached to the plate information for the driver about the requirement to comply with UNECE rules.

Reduce exhaust gas output

When the engine is running, waste products of combustion are emitted. To reduce the level of toxicity and reduce the emission of nitrogen oxides, soot to the standard recommended by international standards, recirculation devices are provided and a particulate filter is installed. Airborne particulate matter is collected and neutralized by a particulate filter and catalyst. If the indicator has lost pressure, it is dirty and needs to be replaced.

System Diagnostics

There are three main types of diagnostics: simplified (by control indicators), complete (using diagnostic equipment indicators), and using flashing codes. Simplified diagnostics show the operation at every power-up and during the entire operation of the motor. AtAt the same time, it constantly monitors the he alth of individual elements of the sensor system, control units and other components in the MAZ-5440. Feedback from the owners of the ICE 7511 suggests that the system transmits a warning or stops the engine in case of critical errors.

If the indicator lights up while driving, it means that you should immediately, without creating a threat of an emergency, stop the car and turn off the engine. Further movement of the machine is allowed only with the help of towing.

Car maintenance

If the operation of the machine is in the first category of complexity, then the frequency of inspection is:

• first service after 15,000 km;
• second repair is done after the vehicle has traveled 30,000 km.

If the conditions for using the tractor differ from the first category, then the frequency of maintenance is set at certain intervals, the period of which is defined in the documents GOST 21624-1981.

In addition to basic inspections, special additional repair and maintenance operations, as well as seasonal work are carried out:

• at the end of the expander tank, the air-steam plug is removed;
• movability of two valves (exhaust and intake) is controlled;
• scale is removed from the surfaces of the tank neck and valve;
• change coolant, oil and fuel;
• replaced air meshfilter;
• cleaning the filter device in the dehumidifier.

Maintenance during warranty period

After buying a car, registering it with the traffic police, the owner enters into an agreement with the service station for maintenance during the warranty period. If there are no specialized stations in the region where the machine is operated, the buyer informs the MAZ service and sales department about licensed transport organizations performing repairs. The manufacturer's management gives written permission to conclude an agreement with this company, and all performed maintenance procedures are recorded in the service book. If such marks are not put, then the enterprise is not responsible.

Varieties of maintenance of MAZ tractors

Depending on the complexity of operations, the frequency and types of repairs, the inspection is divided into daily, after break-in, primary, secondary, seasonal maintenance.

Daily inspection

The car is cleaned and washed every day. Before starting the engine, the fuel supply, lighting and signaling devices, the condition of the hitch, tug and tires, and the presence of a cooling component are checked. After the engine starts, the oil and air pressure, the performance of the brakes and the tachograph are monitored.

Weekly check

The condition of the windshield washer is subject to control. Check the tightness of the nuts on the running and spare wheels, the fastening of the bracket, the condition of the rims, the air pressure in the tires.

Afterreturn from a flight or once every two weeks at the base, leaks of oil, motor fluids, steering, heating system, shock absorbers, cabin lifting mechanism are checked. In addition, the level of liquid in the drive control tank, contamination of the air supply filters, the electrolyte level of the storage tanks, and the absence of drops of condensate in the receivers are monitored.

In conclusion, it should be noted that MAZ-5440 vehicles are popular with owners of transport organizations as reliable working tractors with optimal technical characteristics. A comfortable ride for the driver of the car is of considerable importance, which allows vacancies for such driving to remain in demand.
