How to remove the nozzle on a centaur power tiller

The main reasons why the diesel engine does not start (by the example of a power tiller)

When the diesel does not start, the reasons can not really be so many. The main and most common are only 7. The more complex the engine, the more problems these causes. The simplest example. a single-cylinder diesel single-axle tractor. there can be only one and a half times more malfunctions than causes. Knowing them, you are 90% able to find and eliminate the problem, and successfully start the engine. The other 10% are specific to this or that engine, and therefore the probability of encountering them is not very high.

Even if you consider yourself not a beginner, and have a good understanding of diesel engines, do not be lazy to periodically return to the basics. Very often when there is a problem, your brain flatly refuses to recognize elementary things, which can cause you to overlook the simplest malfunction. So if you can’t get your diesel engine started, remember the basics. This often helps.

Special applications

Air cooling of the engine is not enough to ensure stable, trouble-free operation of such a heavy power tiller. Therefore, water cooling with a condenser is used. Lubrication of the engine loaded components is accomplished by splashing oil from the nozzles.

A feature of the Centaur MB 1012D is the drive on the basis of three high-quality belts, which made this model extremely reliable and practical. Belt transmission does not fail even under maximum load.

Thanks to the double-clutch clutch, gear shifting is easy, and when driving from the field the operator doesn’t feel any jerks and jerks.

In the motor-block Kentavr MB 1012D frame is reinforced, so the engine was placed more correctly, which greatly improved the balance of this model. The operator’s hands are no longer under fatigue while working.

Despite its weight of 260 kg, the single axle tractor excels in some features of a minitractor. it is highly maneuverable and has excellent off-road ability.

This is ensured by the availability of 8 speeds (6 front and 2 reverse) and large wheels (6.00-12) with deep tread chevron type. Thanks to the track adjustment (up to 740 mm), it is possible to adjust the single-axle tractor for row spacing of different widths.

Information on the assembly and operation of the MB Centaur 1012 DE power tiller can be found in the video review.

If you plan to use a single axle tractor in the cold season, consider the model MB Kentavr 1012E with an electric starter. No need to pull the cord endlessly, just turn the ignition key and you’re off. Battery operated electric starter with recharging from built-in generator. Halogen headlight connected to the same circuit, works great when working in the dark.

Centaur MB 1012 D

The single axle tractor Centaur MB 1012d is available in an extended configuration. with an active mill and heavy plow. Another option. MB 1012 DE (electric starter) with an active tiller and heavy plow. Accordingly, the cost of different versions varies depending on the type of configuration of the motor-block, and on average on the market is 46,5. 63,2 thousand.

Centaur” motoblocs

The “Kentavr” gasoline and diesel-wheeled motor blocks are designed for a wide range of agricultural operations: harrowing, cultivation and leveling the soil. They are made in China, which has made the products significantly cheaper and more accessible to the general public. In the domestic market, they first appeared in the early 2000s. and today are considered to be the best in sales.

The range of “Kentavr” power tillers includes devices of lightweight (up to 7 l.с.) and heavy class (over 10 liters).с.), which we will get acquainted with next.

Differences in models

The engine cooling system is either air-cooled or water-cooled.

Italian Power tiller,WEEDAR 9860135370

• The low power and low weight gasoline and diesel engines are all air-cooled.
• Heavy diesel machines with weight over 190 kg (models MB 1070 D, MB 1010 DE) have water cooling.

Air-cooled engines have a longer service life.

When choosing a power tiller, we must proceed from the size of the plot. For a small area on which you are going to plow, cultivate, weed, the optimal one is a gasoline tractor for 6 liters.с. or the single-axle 4L Kentavr diesel tractor.с.

For medium-sized areas up to 1.5 hectares, models weighing from 125 kg with 6-9 liters output are suitable.с MB 2080 B, MB 2091 E.

Separately, it is worth mentioning heavy-duty water-cooled Kentavr engine blocks. MB 1012 D, MB 1081 D versions, designed for intensive use on difficult soils, cultivation of areas up to 4 hectares.

Some versions of heavy power tillers have a halogen headlight to make it easier to work in the dark.

If you plan to operate the single-axle tractor in winter, you can buy a version with an electric starter that runs on a battery: MB 2061D, MB 2091B.

Centaur MB 2061D Centaur MB 2091D

Depending on the purpose, power tillers have an optimal choice of gears. For low power models, typically 2 front/ 1 reversible. Gearbox of heavy modifications features a wider range of speeds. 6 front and 2 reversible.

Some models of Kentavr engine blocks have left the conveyor belt. MB 2060 D, 1070 D, they are replaced by more advanced models made of modern composite materials, equipped with a set of cutters with wheels for the protection of plants, ergonomic, environmentally friendly, with improved design. Kentavr MB 2081 D, MB 2050 DM-2.

Does not start the single axle tractor centaur

Reanimating power tillers after winter and the most common failure of power tillers.

I tried to start a single axle tractor after a winter, but the single axle tractor would not start. How to start a single axle tractor if it does not start can only be speculated at the beginning, because there can be several reasons:

Dismantling and reassembling the nozzle of the motoblock

Like! Before I do my service in the spring, I will watch your videos and I don’t need any books! It’s all clear and straightforward! Thanks!

Yura, can I ask where the spark comes from to ignite the diesel. You have a clip of it.Thank you for your hard work, I watch your channel a lot. and trying to learn. thank you.

@Yurii81 Vorobiov thank you brother. thanks

On a diesel there is no spark, it is more correct to say the fuel injection is early or late, which is ignited under the compression of the piston.

Yuri! video class! And as always! Good luck.

Yuri, hello! Tell me if this is the reason for the single axle tractor and the water at low revs, in the treatment, too, a lot of diesel.What do you advise? ?I’ll be waiting for your answer.

@Yurii81 Vorobiov do you have video to check injection angle?

You need to check the angle of injection and the nozzle on the test bench, but it is better to put a new nozzle.

How do you set the lead on a 61 zirka?

The atomizer is sold with the needle?

Good evening, Yuri. Tell me if it is a one-axle tractor and then starts badly for about six minutes, you need a hand and a starter. It may be from the wrong nozzle settings?

@Yurii81 Vorobiov thank you very much. I will try tomorrow. I took out the injectors and started well before I put them back in and over time they started getting worse and worse. And when I start it, I can start from half a turn, but I have to stand for a while and that’s it

Check the valve at the outlet of the fuel injector, it should hold the pressure in the pipe to the injector.

watched your video before buying a power tiller and after buying your lessons bought a single-axle tractor like you wanted to ask how to reduce the strain on their hands when connected to the trailer trailer trailer is heavy

You could try to put a support wheel that would go up and down like on the car trailers.

So maybe in the recoil pours because the pressure is adjusted by ear? 🙂

Can anyone tell me. if they sell clip-on caps with bumps to hold the nozzle in place? ? Or maybe fit with what ?P.s. I got one of those broken. What’s the correct name for it? ?

Hello.Can you tell me the thread size of the nozzle. On which the nut of the pressure line screws.

Yura, do you know what nozzle may come to the nozzle engine R180.They say it’s from Ford! If you tell me, thanks a lot!!

I also heard that with FORD put, but do not know the brand.

Yuri need your advice. If the nozzle does not make a sound when the machine is started, stop the engine and check if the oil level is within the recommended limits.I’ve disassembled the nozzle in the sprayer needle is running a little tight can this be the reason.the engine rpm is unstable, it emits white smoke.what to do, replace the nozzle?

If cleaning and flushing does not help, replace the nozzle with a new one.

What is the diameter of the old nozzle of the new and old nozzle? Was there a difference in the stroke force with a thinner nozzle needle?

Today I cleaned and put what was there, also I did not want to change the new one, though I did not check the regulator. Why the trip, the power tiller is not a year old and when the machine started losing power and casting a buzzing smoke, saw your video and Ruslan K and decided to take a look, saw the saw blade was three times with a black mark after cleaning, was collected and the engine started working, tomorrow I will try under load because the seeds are still dirty, thank you for the video

Why, under load, may the speed jump??

Most likely the nozzle is leaking, wash (replace the sprayer) and reset on the stand.

Yury tell me please.I have a single-axle tractor 10 hp Zubr needle in rosepelteli 6mm and bought a new nozzle on the packaging says R190 and it has a needle 5mm.I wanted to ask what the thickness of the needle in the nozzle affects and why in the native 6mm and bought there 5mm

I used to use a tractor, the needle was enlarged, everything worked, but it was eating a little bit more, like.

Thank you I did exactly the same, I refined the oil as I saw you with a rod in the nozzle and put it and the work has changed without jamming and no white smoke

Nothing complicated in principle. But I haven’t touched mine yet.

Hello!do you know if the nozzle adjusting spring comes from any other machine??I can not find in my town, I have half a centimeter broke off

Hello Yura. Could you please tell me how far back the adjusting screw should be turned in order to be able to reset it as you showed me??

Thanks. I do not have a test bench, and my friends in the village do not have.

Better to the bench, it is if the situation is hopeless About a half with a spring force

if there is a white smoke when you start up or when you run cold, it is the saw.

@Yurii81 Vorobioviov bike is very difficult to start, it starts if you pour warm water, and hot water starts fine

Yurii81 Vorobiov I’ve been watching the weather, there are a couple of normal days.So I’ll give it a try

And I think after the 20th to throw potatoes, also frozen in the morning.2

Yurii81 Vorobiov I did not plant anything yet.We’ve got frost.But I was planning to plant potatoes for myself on the 22nd.I already experimented so early to plant, it turns out.My method has already planted half the village.At first we were laughing.When it gets warmer, I’ll do it that way.

Sergei Len Hi Seryoga! Thanks for the like. How are you doing, have you planted anything in the garden?

My sprayer also pours well in the back. Today I removed the nozzle. There is soot, screwed the nozzle to the high-pressure tube, twisted the knob, and saw that the spray is good. Do you think it is possible to work on such an atomizer??

If the engine is stable, let it run.

Can you tell me if the atomizers are the same on the engines 180,185,190 are interchangeable or to each need to pick up? I have a shtinley G-185 who bought a single axle tractor no parts

I can’t disassemble the nozzle with a wrench, neither with an old one, nor with a newly bought one. Okay, the old connection might be deformed and welded, but the new one can’t be unscrewed for some reason. Should I take it back to the store or are there any secrets?? I would appreciate an answer.

To figure out the breakdowns and fix them, it’s important to understand how things work in a normal situation. Let’s stop for simplicity only at models with an internal combustion engine. In the past there were two-stroke motor blocks, but now they are increasingly superseded by four-stroke counterparts. Also gaining popularity and diesel units. As for the transmission, it can be made in three different variants.

The traditional approach uses a toothed transmission. Despite a decent level of reliability, this unit takes up a lot of space. The force transmission is accomplished by either a cone or a cylinder. Light power tillers are mainly equipped with a toothed-worm transmission. A typical motoblock regulator principle contains:

The control unit acts on the basis of pneumatic or mechanical linkage. “Pneumatic” means having a kind of wing that reacts to the speed of the air flow. Centrifugal versions involve placing a special camshaft inside the crankcase. It is supplemented with small weights and an easily movable rod. The linkage is made of wire and the sensitivity of the spring determines how accurately the speed can be maintained.

The role of the camshaft is to force a mixture of fuel and air into the cylinder. But the same device also ensures the removal of exhaust gases. to affect the compression ratio, a decompressor is used. Gasoline engines are necessarily equipped with carburetors, which are responsible for preparation of the air-fuel mixture. Regardless of the type of fuel, the starting device plays a major role.

Main causes of breakdowns. why a single axle tractor won’t start?

Cascade single-axle tractor, like any gasoline single-axle tractor, sometimes may not start or start at the first attempt to turn on. The likely causes of this problem could be:

• too low a temperature (heavy engine cooling, fuel)
• Low amount of fuel, insufficient to start and run;
• Low or no oil level
• Improper assembly;
• clogged carburetor jets;
• Oxidation of the electric starter contacts;
• spark plug failure or need for cleaning
• the wire insulation is broken;
• poor fuel quality

do not violate recommendations for fuel and lubricants! This will accelerate the wear and tear of the piston group, the engine as a whole

Cutters on a single-axle Kentavr tractor: assembly with their own hands

For almost every landowner it is of great importance to assemble an excellent harvest, which is impossible without quality tillage in the fall or spring.

Now this kind of work can be done with a mechanism such as a mill. Unlike a shovel, it is more convenient to use and brings excellent results.
