MAZ 4371 is an onboard medium-duty truck with a four-by-two wheel arrangement. The equipment is offered both with a tented platform, complemented by steel sides, and with an open platform. MAZ 4371 is actively used for transporting large loads as part of a road train. The second name of the car is “Zubrenok”. The model for the designers of the Minsk Automobile Plant became one of the most successful and became widespread in the countries of the former USSR. For several years in a row, MAZ 4371 won the “Best Commercial Vehicle of the Year” nomination and maintained its leadership position in its segment.
When developing the car, the designers of the Minsk Automobile Plant took the German MAN L2000 truck as a basis. However, the MAZ 4371 turned out to be much more efficient in terms of carrying capacity, which is why it was named “Zubrenok”. The model was created for use in suburban and urban environments. For this purpose, the developers have endowed the car with compact dimensions, ensuring comfortable movement in congestion and city traffic jams. MAZ 4371 was intended for the transportation of various national economic goods (shoes, furniture, food, equipment, clothing, etc.). The model could also tow trailers with a towbar for backlash-free coupling. The Minsk Automobile Plant also offered a separate chassis for installing special superstructures.
Maz-4370: general information
The described “Zubrenok” is not much different in appearance from its German prototype. From the very beginning of production, MAZ was equipped with German chassis designed for the MAN L 2000. Even externally, their differences were only in the fact that one had a plate with the inscription MAN, and the second - MAZ.
The German truck is not much different from the MAZ Zubrenok. Photos of the MAN L 2000 are almost identical to the MAZ.
MAZ 4370 is a low-bed truck. In terms of its carrying capacity, it belongs to the class of medium-tonnage models. Its tight package, low frame and relatively small size ensure leadership in urban and suburban environments. The maneuverability of the MAZ allows you to turn around anywhere. As a vehicle for transporting goods, it has no equal, since that same low frame simplifies the loading and unloading of the vehicle, which allows it to be done in the shortest possible time.
MAZ 4370 can also be used for long-distance transport. For this, the truck is equipped with everything necessary. It can turn into a tow truck, dump truck or other cargo transportation construction equipment.
Device
Control in earlier modifications is carried out through a gearbox produced at the Likhachev plant. It is quite sufficient for use in urban conditions. With foreign units, a 5-speed transmission ZF S5-42 (ZF 6S-850), produced at Hungarian or German factories, is usually used.
One of the disadvantages of the Zubrenok is the lack of a differential lock and a four-by-four all-wheel drive version. This makes it difficult to move on off-road and rough terrain. The MAZ 4371 model has always been positioned as a car for the city.
The braking system is built on drum brakes. However, there are also modifications with disc brakes.
The MAZ 4371 cabin deserves special attention. It is this element that significantly distinguishes the model from its predecessor (MAZ 4370). Instead of a short cabin without a berth, a more spacious cabin was used. In terms of comfort, it is not much inferior to foreign products. There is no provision for a third place. There is also no free space for installing a sleeping place, which in certain cases can cause inconvenience. However, the cabin is quite warm and there is no engine tunnel. The soft suspension does not tire the driver even during a long journey.
In terms of comfort, users note that the third seat is useless, and installing a berth can be difficult. But the cabin is very warm, there is no engine tunnel, which usually gets in the way, and the suspension is quite soft and does not tire you during a long journey. There are handrails on the sides of the doorways to make entry easier.
There are no air cylinders or spring struts for the cabin. It is attached to the frame through special rubber bushings. The developers of the MAZ 4371 did not skimp on the hydraulic lift and hydraulic locks, which provided convenient access to the engine and windows. The model’s dashboard is considered the best among all products produced in the post-Soviet space. In design it is only slightly inferior to its European counterparts. Thanks to new technologies, it was possible to make it non-creaky and soft. A plastic shelf appeared above the windshield. The rear part of the cabin wings is mounted on the frame. In essence, they are plastic fender liners that protect the wheel arches. However, the vehicle's cabin is not suitable for long-haul transportation. Another disadvantage is the poor protection of the cabin from corrosion. The abundance of galvanized parts helps with this, but the developers failed to completely protect the element from harmful effects.
It is no coincidence that MAZ 4371 is considered the most successful product of the Minsk Automobile Plant. It contained the latest developments of the enterprise.
Spare parts for the MAZ 4371 car are very easy to find. The manufacturer supplies a wide range of them to the Russian market. The truck can be serviced and repaired at any service center.
Pros of the model
The Minsk Automobile Plant is taking impressive steps towards equating its products with Western analogues. The most important advantage of the truck is its relatively low price, which is significantly lower than that of high-quality European products. Maintenance of this vehicle will cost less than the same MAN L 2000. Of course, replacing or repairing some part from Zubrenok will cost less than the same German truck, but, according to statistics, MAZ breaks down more often.
The model performs well on domestic roads, which is greatly appreciated by all drivers. Buyers are attracted by the versatility of the truck, because it can be used for both urban and regional cargo transportation. The car's high load capacity of five tons gave it considerable popularity.
Many companies fundamentally drive only imported cars, citing the poor quality of domestic cars. To some extent, they are even right, but the MAZ Zubrenok is almost in no way inferior to European vehicles. Therefore, having stopped at it, the driver will not regret his decision. This truck harmoniously combines two main factors - price and quality.
Deutz Q&A
Question:
Hello, please tell me I have a Maz Zubrenok 4371 Doets Euro 3 2012 170 horses. Is it possible to increase the power, chip or flash it using some method? Thank you. Nikolay
Answer:
Nikolay, our company does not provide such services, but in practice it is possible. However, I note that increasing its power has a negative effect on the durability of the engine.
Question:
I have a ZF five-speed with a Deutz engine. In principle, it works fine, although there are some problems. They advised me to replace it with a ZF 6S36 gearbox. Friends installed it and are happy. Tell me, is it worth doing?
Answer:
We will refrain from giving advice. We can only say that the ZF 6S36 gearbox has well-chosen gears. If you decide to change it, you will have to replace the front cover and the release bearing flange. The release fork and bell will also be replaced. You can use the old pneumatic hydraulic clutch booster. So the costs will be quite significant.
Question:
There is a problem with the ZF 6S36 gearbox (installed with the Deutz 1013 engine) - noise occurs, especially at idle. However, when I press the clutch, it disappears for a while. There are no other faults, the box works well. What could be the reason?
Answer:
There may be several reasons. For example, there were problems with the input shaft bearing. Or the noise is caused by the clutch disc damper. We need to understand our service.
Question:
I work at Zubrenka. It has a Deutz engine and a ZF 5S42 gearbox. On the route, problems arose with the gearbox; the input shaft, bearings and constant mesh gear had to be replaced. We assembled it, checked it, drove it for break-in carefully without and with load. I noticed that the bearings on the intermediate shaft began to heat up. Then a crunching sound began to be heard in the gearbox (in 5th gear). The front bearing of the intermediate shaft literally fell into pieces, there was a lot of sawdust. Tell me, what is the reason?

Question:
My Deutz 1015 engine was overhauled; it was completely dead. I thought that oil was not passing through the fuel injection pump, so I took it to a service center to clean it and put it in order. The engine ran for several days, then the amplitude began to fluctuate. A few jumps and at high amplitude the engine stalls. Tell me how to solve this problem?
Answer:
There is not enough information to name the exact reason from among the possible ones: the magnet bushing could be worn out, the adjustment was made incorrectly, the position sensor does not work correctly. Come to us, we will help. If you're looking for a solution yourself, start by removing the rack plug to see how it behaves when the engine is running.
Question:
I replaced the fuel injection pump (Deutz 1013 engine) with new ones. I installed it the same way the old pumps were. But after replacing it, thick black smoke appeared. It looks like the diesel fuel isn't burning out. This means I made a mistake with the installation. Tell me how to fix the situation?
Answer:
Yes, you most likely installed the injection pump incorrectly. The rack must be locked before installing the pumps (the car manufacturer offers a special device for this). Then the pumps are installed in order. The installation order should follow the order of their removal. When installing new pumps, it is necessary to select compensation washers. This operation has its own subtleties, so it is better to do the work with us.
Question:
After replacing the piston sleeve group, we started having problems with the Deutz 1012 engine. Fuel stopped flowing to the injection pump. There is no manual, we can’t figure it out ourselves. We tried to supply power to the 24V valve, which is located between 2 and 3 of the fuel injection pump, but to no avail, a click is heard, but fuel still does not flow. Tell me what should be done?
Answer:
Without diagnostics, it is difficult to pinpoint the exact cause. It is necessary to check the fuel pump and check the power supply. An electric valve is installed between the fuel injection pump on the block; the power supply to it also needs to be checked. Contact us, we will quickly figure it out and fix the problem.
Question:
I checked everything 100 times. I looked at all the wires. This is not the case when it's cold. Traveled 50 km. I turn it off, start it up, and immediately when I press the pedal it starts shaking and pours out smoke, shaking like a semi-truck. Alexei
Answer:
Alexey, one or two cylinders are not working on your engine. Come for a diagnostic, we will determine the cause of the problem and fix it.
Question:
The Deutz 1013fs clears out and thick smoke pours out at 2000 rpm; if you push further, it seems to start working. Alexei
Answer:
Hello, check the tightness of the fuel system and the operation of the injectors.
Question:
The engine of the Deutz 2012 began to smoke black smoke. The pressure is good and there are no knocks.
Answer:
Check the air filter and replace with a new one.
Question:
The Deutz 4.8 engine does not pull, does not develop full power, but does not smoke. What is the reason?
Answer:
The most common cause of such a malfunction is a decrease in the permeability of the coarse fuel filter and a decrease in the permeability of the fine filter. Many conscientious drivers change the fuel filter after the mileage specified by the manufacturer. But you need to take into account that for foreign cars, the manufacturer’s recommendations are not always focused on the country where the equipment will be used. There are times when water and dirt get into the fuel, so in order not to harm the engine and not lose power, the fuel filter should be changed twice as often.
Question:
We bought a new Deutz 914 engine and ran it in. We had just started working when a knock appeared in the engine. They turned it off immediately. The engine itself is jammed, and there is damage in the 4th cylinder and the liner is also damaged. Tell me, what was the problem? And can you help?
Answer:
Yes, we can. There are several causes that can be identified by characteristic signs after diagnosis.
Question:
The workshop told me that I had problems with the turbine. My engine is Deutz 1013. Looks like a replacement. But I'm not very sure about this. Can you help and check, and if necessary, install a new one?
Answer:
Yes, we can, but you need to clarify what kind of engine you have: with the BF4M 1013FC internal combustion engine, a Schwitzer TKR 318807 is installed, with the BF6M 1013FC internal combustion engine, a turbocharger of the same brand 318815 is installed.
Question:
I changed liners along with piston rings on the Deutz BF4M 1013 engine. I replaced the head gasket and connecting rod bearings, then tightened the head in accordance with the manual (I used a dynamometer). It so happened that the engine was practically not run-in, it went straight to work. A couple of days later I discovered cracks on two sleeves, and two were completely torn off. There were also bullies. Yes, I installed wet cartridges. Tell me what could be the problem?
Answer:
We pay attention to two points. During installation, the sleeves must be ground against the collar; possible “sag” is eliminated using special adjusting rings (they can be copper or brass). Rings come in different calibrated thicknesses. The thickness of the gasket must be maintained, otherwise the volume of the combustion chamber will change.
Question:
I can’t find information on whether it is necessary to retighten the cylinder head bolts after replacing the head gasket. Engine Deutz 1011. And what do you recommend based on your experience?
Answer:
The manual says that after 500 hours of operation, only the valve clearances need to be checked (section 3.1.5 “Additional maintenance work”). From our practice, we can say that it is advisable to reupholster when installing a gasket under the cylinder head made of paronite. The metal gasket does not require tensioning.
Question:
Need some advice. My Deutz 1013 engine has covered a little more than 250 thousand km. Now I need to install the cylinder head gasket, but a problem arose because the first time I had three liners break almost immediately after installation. In this case, all sleeves have the same output.
Answer:
We believe that the reason is most likely not the gasket (a properly selected gasket, together with the protrusion of the piston, gives the required combustion chamber height). We recommend measuring the seats for the sleeves. The recess should be 8.92 mm, and the shoulder should be 9.00 mm. And you didn’t say whether the shells tear along the upper collar.
Question:
Hello, the Deutz bf4m1013fc engine loses traction at 1700-1800 rpm downhill and then recovers. And if you drive 20 km and turn it off, it is very difficult to start, but when you start it it takes 5 seconds, the filter has been changed, the booster pump has also been replaced, the tank is clean. I don’t know what to do anymore. Maksim
Answer:
Maxim, check the bypass valve.
Question:
MAZ Zubrenok engine Deutz. It emits blue smoke. The engine is tripping. Ainur
Answer:
Ainur, blue smoke from the exhaust pipe indicates a malfunction of the fuel equipment. Come to our company for diagnostics, we will determine the problem and fix it.
Question:
After reading the questions in this forum, I conclude that I am not the only one with this problem. Engine deutz bf4m. When cold it works normally, after warming up it starts to stall in a certain rpm range from 1500 to 1800 and pours out blue smoke (unburnt fuel). We have been trying to solve the problem for several months. And as I was told, no one in Russia has yet won this. The air leak was ruled out, the turbine blows perfectly, there are no errors, the injectors were made by removing the outlet. The collector found out that smoke was coming from all cylinders. The brains, the pedal and all the wires were tossed up to no avail... and for some reason it troits when the outside temperature is from 0 C to 10 C approximately... please tell me what the problem is. Vitaly
Answer:
Vitaly, unfortunately, we do not have an answer to your question.

GOOD AFTERNOON. THERE IS A PROBLEM WITH THE COLD START OF THE DEUTZ BF4M 2011. AT PLUS TEMPERATURES IT STARTS WITHOUT PROBLEMS. NOW IT'S ABOUT MINUS TWO, WITHOUT ETHER THE AIR FILTER CAN'T BE STARTED. IT WARMS UP FOR 10 MINUTES. IT STARTS THE FIRST TIME. SOLENOID VALVE CHECKED ALL OK. THE INJECTORS ARE NEW, THE FUEL SYSTEM IS SEALED, THE ENGINE DOES NOT TAKE OIL, ALL FILTERS HAVE BEEN CHANGED, THE STARTER SPINS WELL. NICHOLAY
Answer:
Nikolay, check the engine compression cold and hot, if there is a difference, “dig” further, but best of all, take the car to a service center for diagnostics.
Answer:
Evgeniy, it is necessary, starting from the fuel intake in the tank and ending with the last fitting on the injection pump, check the fuel system for leaks (create excess pressure in the line) and again replace the check valve with a new one.
Question:
The pressure in the Deutz 1013 engine drops after a major overhaul of the internal combustion engine installed on the MTZ 3022. Tell me what to do? Anatoly
Answer:
Anatoly, check the pressure in the lubrication system with a mechanical sensor; if the result does not change, then the reason for the pressure drop is more serious and must be looked for in sequence: oil pump, crankshaft, camshaft, and it would be good if specialists dealt with this issue
Question:
Good afternoon, the Deutz BF 6M 1013 FC engine has antifreeze in the sump, could you tell me why? Eugene
Answer:
Evgeny, antifreeze can get into the pan through a damaged cylinder head gasket, through a crack in the cylinder head, through a crack in the liner, and also after severe overheating of the engine if the geometry (plane) of the head is violated.

What attracts drivers to driving a MAZ-4370?
According to driver reviews, this on-board vehicle is very comfortable. The cabin of the MAZ Zubrenok has almost no flaws. The technical specifications are also excellent.
In terms of build quality, none of the domestic automobile manufacturers has surpassed it. The fact that it does not have a hood provides additional space, which is especially important on long flights. Even three people (there are three seats in the cabin) are not cramped in such a car.
Winter flights usually brought a lot of trouble to truckers. One of these troubles is low temperature in the cabin. The MAZ “Zubrenok” has an excellent heater built in, which will warm the driver if necessary.
Another good advantage of Zubrenok is its smooth ride. The excellent factory suspension and various devices cope well with external vibrations and strong shaking on “killed” roads, which makes long driving less tiring.
Truck Specifications
The most important thing is the engines supplied to the Zubrenok MAZ. The technical characteristics of the truck are directly proportional to the engine power. In this regard, the plant has constantly improved the “heart of Zubrenok”. The very first models were equipped with the old MMZ D-245.9-540 with a power of 136 horsepower. Even the first cars were equipped with five-speed gearboxes from ZIL. Later they began to use more powerful diesel engines, designed for 155 horsepower. The engine on the MAZ “Zubrenok” MMZ D-245.30 was equipped with a five-speed gearbox 3206.70. If from the very beginning of production cars with Euro-1 standard engines came off the assembly line, then after modernization new ones began to come out, with Euro-2 standard.
The first engines on Zubrenok had the same global problem - very strong noise and vibration, which really distracted from the road. All this is due to the fact that MMZ D-245 was once produced as a tractor engine.
Car modifications
In addition to various power units, the car has wheelbases of several lengths:
- 3.30 m;
- 3.35 m;
- 3.70 m;
- 4.20 m.
This number of options definitely serves as additional popularity for the truck. In addition to the standard cab, a double cab with a berth is available.
in combination with a variety of engines and different wheelbases produces the following modifications:
- onboard;
- side tilt;
- dump truck;
- van;
- isothermal van;
- chassis;
- tow truck;
- onboard with CMU.
A significant number of modifications, wheelbase options and cab designs have significantly expanded the scope of application of the MAZ-4307.
Fuel consumption
One of the important factors when buying a truck is fuel consumption. All costs of operating a truck depend on this indicator. Compared to other similar vehicles, the MAZ Zubrenok has a fairly favorable indicator - its fuel consumption per 100 kilometers is about 22-24 liters. This is not as much as for vehicles produced in the CIS countries, but many European brands of trucks have lower fuel consumption.
Experienced drivers say that with proper driving and appropriate settings, diesel consumption can be reduced by 4-6 liters. If a skilled mechanic at a service station can achieve such an engine setup, then Zubrenok will pay for itself very quickly.
It’s not for nothing that the MAZ 4370 received its popular name – “Zubrenok” – for its high characteristics. Such a vehicle was in demand, and Minsk Automobile meets all the parameters of a modern cargo transportation vehicle.
Advantages and disadvantages of the car
Owners in their reviews of the MAZ-4370 highlight the following main advantages of the truck:
- affordable price;
- comfortable cabin;
- traction parameters of engines;
- economical operation;
- low loading height;
- large platform area;
- compact sizes.
Among the disadvantages most often noted:
- low heater power;
- frequent breakdowns of the rear axle gearbox;
- gearbox defects;
- rapid wear of the clutch disc;
- spring failures.
Despite the presence of shortcomings, especially at the initial stage of production, due to its carrying capacity, cost and the availability of a large number of different modifications, the MAZ-4370 medium-tonnage truck is in stable demand. The improvements and modernizations carried out allow the Zubrenok to remain the most popular truck in its segment.
