Maz 4370 Technical Characteristics Fuel Consumption • Technical parameters

The design of the double cabin includes a sleeping place, thanks to which you can feel quite comfortable on the road: if the driver is tired, he can simply park in the nearest suitable place and rest.

The Minsk Automobile Plant began production of MAZ-4370 trucks in 1999. In 2003, the car was recognized as the best in its class. This model received the nickname “Zubrenok”. The German MAN L 2000 was taken as the basis for the development of the truck (the carrying capacity of the Minsk product is twice as large). Initially, the MAZ-4370 was equipped with exclusively foreign cab and chassis. However, later its own chassis was created. The 5-ton truck differs from its analogues in having a low body frame, which makes unloading and loading easier. The model is intended for regional, suburban and urban transportation.

The main purpose of the MAZ-4370 remains the transportation of cargo for various purposes in urban environments and on intraregional routes. The truck is intended to be used as part of a road train. Quite often, Zubrenok is used by city services as a tow truck. The vehicle chassis is also equipped with various lifting devices, dump trucks and manipulators, tank trucks and other equipment. This allows the car to be used in almost all sectors of construction and production. Some models are equipped with comfortable cabins equipped with a folding berth, which makes it convenient to use the car when traveling long distances.

Starter turns but won't start

If the starter of a MAZ-4370 truck spins when you turn the key in the ignition, but the engine does not show any signs of “life”. The cause of the malfunction may lie in both the electrics of the truck and the mechanics. The causes of electrical malfunctions can be as described earlier, in addition to faults associated with the starter and its circuits, additionally the following reasons:

• Failure of the high pressure fuel pump (HPF)
• Mechanical engine failure
• “Airing” of fuel equipment
• Lack of diesel fuel in the tank
• Fuel filter clogged
• Clogged fuel lines
• Check valve malfunction
• Mechanical failure of injectors

The car, based on the German MAN L 2000, was presented in the summer of 1999, at the same time its mass production began at the facilities of the Minsk Automobile Plant.

Model range Technical characteristics

As a result, the MAZ-103 bus was developed, on which a rear axle of its own design was used instead of the portal axle installed on the MAZ-101. In the second case, when hired, the driver was notified of compliance with the speed limit, working on the line with a full load and observing the speed corridor within 60-75 km, the driver achieved the most optimal consumption, which was confirmed by the AT-Observer GLONASS system.

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?

Externally, the MAZ 4371 was practically no different from the MAN L2000. Moreover, the first batches of the Minsk product received a German chassis. However, then its own chassis was created. They began to install a new cabin on it.

For a long time, the MAZ 4371 was considered one of the most advanced trucks. However, car owners criticized the car even then. For this technique, headlights made in China and characterized by low power were used, so the lighting of the model was rather weak. Experienced drivers replaced this element immediately after purchase.

In general, reviews from MAZ 4371 owners indicate that the car is a good alternative to foreign analogues. The model is highly reliable and durable and is perfectly adapted to the Russian climate and roads. In the category of medium-duty trucks, the equipment fully meets the needs of the market.

Is the clutch sticking? Don’t rush to look for MAZ Zubrenok spare parts

When the first Zubryatas with foreign power units and gearboxes appeared, a slight embarrassment arose: service stations, under warranty, quite often changed MAZ Zubrenok spare parts, such as the flange in the gearbox clutch. As the drivers said, this happened after a short time. The first symptom is a stiff pedal, and then after a short period of time - failure of the flange. But thanks to the handy owners who are not in a hurry to go to the service for every reason and figure out the cause of the breakdown on their own at the first event, it turned out that this could have been avoided. The reason for the failure of this part is lack of lubrication. Banal factory sloppiness.

However, even if this unit is lubricated, it still requires maintenance over time. And, again, the first symptom is deterioration in the clutch pedal travel. Or, as drivers say, the clutch becomes tight. In order not to spend money on MAZ Zubrenok spare parts, in this case we recommend lubricating the release lever, for which:

Remove the engine protection from below

Unscrew the adjusting bolt (from the clutch fork)

Disconnect the fork from the PSU pusher

Move the release bearing as far as possible from the basket

Move the release lever close to the basket and lubricate the flange on the other side

Apply oil liberally to the clutch fork seat on the release bearing

Putting everything back together

After you have completed all the operations, the clutch on your Zubrenka will be like on a car. And the sooner you lubricate the release lever and flange, the later you will have to look for MAZ Zubrenok spare parts.

The exhaust pipe of the Zubrenok is clogged

The work came from the glorious, fighting city of Petushki, Vladimir region. The MAZ Zubrenok car did not want to start; the organization’s mechanic and third-party specialists suffered with it for a long time. Three whole months. The car stubbornly wouldn't start. They called us in, hoping that the work would go faster if we hid the nuances that would provide the chief mechanic with a period in his career to higher-ranking bosses, but it didn’t work out that way. All the secrets told to us were, in fact, not secrets at all; the car was so interesting in its present form before us that we decided to write an article about it as a separate item.

Electronic diagnostics showed on the car what the essence of its error was and the car complained about a lack of oxygen in the engine. It would seem that this initially had to be determined fundamentally and not worry about it, but then other questions arose. Suspicion fell on a mechanical malfunction during the synchronization of the camshaft and crankshaft sensors “count” 48, setting the ignition marks, the integrity of the resistance coils of the crankshaft and camshaft sensors, the required fuel pressure, and, accordingly, with the working pump of the fuel injection pump and low pressure pump, but at the same time the car had a USR valve . The specialist made the necessary measurements of voltage and voltage on the necessary fuel system sensors, after which they concluded that it was a miracle - everything in the car is working properly, but it still won’t start. A miracle, as we all know, does not happen, so we continued our search deeper - since there are no electrical faults, it means we need to look and dig deeper, right down to disconnecting and looking into the muffler. The exhaust gas pipe seemed to be normal, as was the USR valve (exhaust brake, engine brake), but upon closer examination of the injection and exhaust system, one very important point was revealed: for some reason, the exhaust smoke started from the boost manifold pipe. That is, in this way, the exhaust gases turned off the engine and did not allow it to work in normal mode.
