Checking the MTZ-12 engine block. Properties, operating instructions
The farmers often ask me about the heavy motor block MTZ-12, its parameters and the expansion of functionality. I have to say that this is the last apparatus in the floor equipment of the individual axis equipment of the MINSK tractor plant.
It is intended to carry out agricultural measures and work the transport of goods in the municipal area. According to the manufacturer, the machine was discontinued, which forces the owners to repair the old devices until the full exchange of individual nodes.
Description and properties
The main feature of the technology is a significant force, which means that 12 model in the heavy class is produced one of the most popular units. Belarusian technology loses popularity on many of the same models, but is more reliable.
The actual purpose is considered universal. The tractor of the walk behavior is quite able to completely replace the tractor equipment. The popularity of other similar options is due to a cheaper engine and more efficiency. It should be taken into account that MTZ can be used under the conditions for which competitors are not suitable due to their operating data.
Important! The equipment should be used according to the administration and instructions for management and operation. Violations can lead to problems and wear of parts.
The main chest of the unit is a large amount of work that can take place in a short time. The model is designed for an increased type of operation.
In this video you will learn more about the MTZ 12 Motoblock:
Equipment for MTZ engine blocks suitable
The modernization of the MTZ Motor note can be carried out independently. You can add devices that expand the spectrum of the functions carried out:
- Hiller;
- Singl e-I n-Pflug;
- Hinge mower;
- Cinquefoil cultivator;
- a semi trailer that can contain half a ton;
- Harrow.
All of these adhesive devices enable you to increase the number of functions performed. If you select an additional detail, rely on the tasks that the engine block will run. You can convert it into an ATV into a plow or a potato waste – you should select the option that is required in a certain situation. This unit is an excellent labor mechanism, and its refinement can be made at any time, all devices are bought separately.
Standard feature without modifications
Important! In changes, the properties can change slightly depending on the modernization of the devices.
The number of speeds is standard and 4. A further 2-countered use is used, with which you can turn around in a small area. It should also be noted that the walking behavio r-tractor is characterized even despite the significant mass by controllability and compactness.
If necessary, pneumatic bikes can be used by other types of devices. The installed load capacity is 650 kg. In fact, the load capacity is much higher.
Depending on the design features, the equipment allows you to convert it into a small tractor, which, when using a PTO shaft, can perform almost any agricultural work.
When using the drive, all common agricultural implements can be used.
options
I was struck by the technical characteristics of the device: a two-cylinder engine that produces 11 liters. with., solid transmission and large wheels create the illusion of a full-fledged tractor. In fact, the walk behind tractor will be one in conjunction with a specially designed adapter.
As a user, I would like to see a durable European or Japanese power unit in a walk-behind tractor.
However, our engines are less whimsical about the quality of fuels and lubricants, which is important when working in rural areas and problems with the delivery of technical fluids. In addition, the MTZ-12 can sort out a mechanic with minimal knowledge of repairing gasoline vehicles.

The four-speed manual transmission offers 4 forward and 2 reverse gears. At the maximum level, the walk behind tractor moves at a speed of 9.6 km/h.
ignition timing
Ignition timing has a set order. First you need to check the performance of the candle.
Important! With each setting, the candles used must work. For this purpose, they are checked in advance. It is also important to change them in time. The usual exchange takes place quarterly. With continuous operation, the candle should be changed more often.
The setting is inevitably carried out during an enema. Every process of retracting implements, even after a standstill, requires the ignition on the two-wheel tractor to be set.
- the candle is checked, which must be clean and also in working order;
- If necessary, all the soot of the candle is removed. The distance between top (middle) and side contact is adjustable;
- a cap is placed on top of the candle;
- The engine is started manually. In this case, the candle is brought to the body;
- The spark should be good and bright. If there is no spark or weak, the ignition system and its parts need to be replaced.
Other parts of the ignition system are checked in the same way. The entire process is carried out until the ignition is properly timed, allowing you to quickly start the walk behind tractor. This has a positive effect on the wear resistance of parts, as well as work efficiency.
Malfunctions of MTZ engine blocks and do-it-yourself repairs
Of course, the most diverse breakdowns can occur during use, which are discussed in detail in the instruction manual. Today we will only focus on a few issues that are the most relevant.
| problem | solution |
| What if full torque is not being transferred from the clutch? | You need to adjust the clearance, replace the compression springs and check the mobility of the discs |
| What to do if the clutch does not obey? (does not turn off) | You should also stop the game, shorten the cable or replace it entirely. |
| What should I do if oil is leaking through the clutch control adapter? | It is important to replace the ring quickly and qualitatively |
| What to do if excessive noise appeared in the gearbox? | It is necessary to adjust the lateral gap in the engagement of the six talks. |
| Pressing sources are seriously slaughtered | They need to be replaced |
| Disks on the slots are reduced in size | You should check the mobility of the discs and eliminate the barrier |
| Wear of the sealing ring and boot | Replacing details is a solution |
| Self-improvement of the nut of the driven percussion | It is important to properly consolidate this nut |
It should be understood that the period of trouble-free use also largely depends on the competent preparation of the device. Therefore, before starting a block of motorcycles, carefully study the advice of the manufacturers described in the management.
Adjustment of the valves
Valve adjustment is performed during the running process, as well as similar adjustments. The adjustment should also be made after a long working process or downtime. This is due to the fact that the shameful dimensions are constantly changing due to wear of parts or without proper consolidation of mechanisms.
- disassemble the case and remove the oil bath;
- The nut is weakened and the blade is grasped;
- The blade’s walking is delayed by a nut;
- The process continues until free movement of the valves is eliminated.
- The size of the release can vary from 0.1 to 0.15 mm;
- After the end of the process, the case and the bath are put back;
- All fasteners are delayed. This is interesting: The characteristics of the engine block beam MB 1.
Do not forget about the adjustment of the valves of this walk tract with proper adjustment that the valve will pass freely, but at the same time there will be no extra space.
Heavy motoblock MTZ-09
MTZ-09N, developed in 1992, is a serious model of a professional level, which is the largest under the MTZ brand, the main area of which is the use of small agricultural production small agricultural production, urban agriculture for snow cleaning and garbage cleaning, as well as transport small goods.
By 2009, 15,000 machines of this modification were produced, the geography of which included the countries of the Baltic States, Venezuela, the USA and Ukraine.
The main differences between the MTZ-09 engine note:
- Durable housing and wheel filled with air;
- The ability to control engine speed;
- Low noise level;
- High ergonomics of government bodies;
- Allow to easily control the device, which provides the stability of the machine with a large weight and a good balance of the structure.
power point
The first versions of the models were installed by the OT-15 and UD-25 series engines, which were subsequently replaced by more modern power units.
Today, the MTZ-09 is equipped with a long-term continuous regime through power units of various modifications, equipped to consume AI-92 and AI-95 gasoline.
In most cases, the MTZ-09 supply set includes a four-stroke single-cylinder nine-strong power plant Honda GX270 with a volume of 0.27 liters and the speed of rotation of the shaft revolutions 3600 per minute.
Along with Japanese engines, the model is also produced with similar parameters and lower cost of Chinese engines Lifan LF177 and Kipor KG280, as well as engine Jikov GH1509 Czech assembly engines.
draft
When creating MTZ-09, its developers used nodes and units from tractors manufactured at the enterprise.
engine replacement
With every cultivator, also with the MTZ singl e-axle tractor, the engine should only be replaced after a complete further entry. This is necessary due to the grinding of all parts. In some cases, the engine is replaced even when the elements are weared partially. This is possible because there are various options for repair parts on the market, including those that are already included in a complete sentence.
Important! The engine in the unit should be replaced by a specialist in a special service center or a person with practical experience in dealing with Belarusian devices, as there are special features compared to other manufacturers.
There is also a certain order after each exchange of motor elements, including complete:
- After installing the mechanism, all connections and elements are checked;
- Filled with fuel (gasoline) and oil. It should be noted that the fuel must be clean, ie without additional contamination by water or other consistencies, as well as high quality;
- Drive in at least 50 hours, but without full load;
- Handl e-guided tractor must be washed and cleaned;
- Oil and all lubricants are changed;
- The fuel filter is cleaned;
- The operating status of the clutch controls on the clutch and the throttle valve is checked;
- All fastening elements are checked.
It should be noted that the ignition must be installed and the valves have to be set when entering. Otherwise, the wear of parts and elements can begin again.
Gradually preparation of the device for operation
- We wash MTZ 12.
- We change the oil in the engine and wash the oil filter.
- Rinse the swamp of the fuel tank valve.
- Change oil in the gearbox.
- We check and adjust the entire management mechanism.
- We check all fastening elements and the air pressure in the wheels.
- If problems are found, we will fix the problem immediately.
You can find all the details of setting up equipment in the repair instructions. However, if you understand that the repair of devices is not for you, it is best to simply bring the devices to a service center.
User Guide
This model of the han d-led tractor is easy to use – this is made easier by the simplicity of its device. The machine is included, here are just a few tips for the correct preparation and use of the mechanism.
- Before using intended use, it is necessary to let the device run with the lowest performance at idle in order to make it easier to grind the gear and engine parts.
- Do not forget the regular lubrication of the mechanism components.
- The tap shaft may only be switched on when the engine speed is reduced and the clutch is switched off, otherwise there is a risk that the balls will fly out and the gear breaks.
- Additional attachments must be attached clean and safely. Don’t forget the fixed installation of the Kingpin either.
- Before using a handled tractor with a trailer, the functionality of the brakes of the mechanism must be carefully checked.
- If you work on excessive heavy and wet soil, it is better to replace wheels with air tires for tunnels – slices with special panels instead of tires.
For proper and long-term use of the MTZ-12 you have to set the clutch. If the singl e-axle tractor shrugs when pressing the clutch, it is worth tightening the adjusting screw. If the han d-led tractor moves more slowly when the clutch is dissolved than it should, the screw must be easily dissolved.

For those who want to get acquainted in detail with the characteristics, as well as the features of the operation of carburetor engines previously used on MTZ engine blocks (SK-6, SK-12), this opportunity is available by clicking on the link below:
If we compare two tables with technical specifications for the hand-led tractors MTZ-05 and MTZ-06/12, we can conclude that these models are identical in their parameters, with the exception of the engines used, the Belarus model can be said 08/09, in which high technological and reliable engines are used abroad.
Operating characteristics
The following work is carried out before the first use of the purchased singl e-axle tractor:
- Check all connections;
- Fill the required amount of oil and gasoline. The fuel must be free of water and mechanical particles;
- Perform an enema, which means that all parts are entered and the lifespan of the device is extended.
After completing the enema, which takes around 50 operating hours, the following actions are carried out:
- Wash the han d-led tractor;
- Change the oil in the engine tub, wash the oil filter;
- Wash the fuel filter;
- Change the lubricant in the transmission and in the gearbox.
- Check the function of the clutch and throttle valve control mechanism.
- Check all fastening elements.
Adjustment of the valves
After long operation, the valve games of a tw o-cylinder engine must be checked when maintaining maintenance, which usually change. This is due to wear parts. If the distance is not sufficient, errors occur in the operation of the power supply and the specified performance is not generated.
A distance of 0.1 to 0.15 mm is considered correct. Proceed as follows:
- Disassemble the housing and remove the oil bath;
- Loosen the mother with a screwdriver, then insert the blade and tighten it;
- Concentrate on the blade and slowly pull the mother tight;
- In this way, a setting is made until the free movement of the valve is eliminated. Check density;
- Use the oil bath and the housing again.
Below is a video overview that shows the valve setting on a han d-led tractor
