How to adjust the regulator on a walkbehind tractor.

How to adjust the centrifugal regulator on the walk.Behind engineer video

In the flea rows inside the pavilion, I could not pass by the Wunder device of the Patephone. I was always interested in how it is arranged. Although the general principle of work was approximately understandable, it was not before that it was not possible to see and feel its implementation. For a completely lifting amount, a battered, but the working paterphone presumably the 40s of the last century (from the words of the seller) left the exhibition with me. There are many spare needles as a bonus.A little pedvikia:

Pateton. A portable version of the gramophone, a mechanical device for playing gramophone records. Unlike the gramophone, the pratefond has a small mouthpiece and is built into the case, the device itself is combined in the form of a suitcase, it is transferred in a fastened form for a special handle.

Was widespread in 20-40. XX century. Was later supplanted by an electrophone.

The name “Patephone” comes from the name of the manufacturer: Pate.

The invention of the “portable gramophone” belongs to the company “Decca” 1913.

The mechanism was intended for use in the field for armed forces of England. The design of portable mechanisms reached special popularity in England by the beginning of the 1920s and over the next decade, these mechanisms were advertised extensive, as an ideal for use on picnics, campsite, and rowing.

So, we analyze this forefather mp3 players, fie how it works, and at the same time clean/lubricate.

Firstly, we examine the identification signs on the case. There are only 2 of them: the manufacturer and the name of the model

H1 Trailer Tutorial Build

The head is a semblance of a speaker, which is directly connected to a needle and is controlled not by electrical impulses, but by mechanical vibrations (techies in this place are made by Facelpalm). The sound passes through the hole in the center and then follows the pipe before the exit, which is located inside the prateophone.Needle:

We see that the brake (below) in the “vkl” position is approached by its short end to the drive, where a special ledge on the back of the disk, which is now removed, and thus the rotation stops into it. In the “automatic” position, the brake lever is pushed by another lever, which, in turn, is associated with the holder of the head. The plate ended, the holder of the head moved to the center, pushed the brake and the plate stopped.The speed regulator (on the right) is driven by some lever sticking out on the back of the panel. Unscrew the screws around the perimeter and remove the panel along with the clockwork mechanism, which is screwed to it from below.

Everything is clear here: according to the principle of the Ruper, the sound goes from the head and intensifies, intensifies, intensifies. Having left the metal pipe, it enters the box that serves as an additional resonator. Please note that all places of contact of the pipe with the body, as well as between the case with the panel removed, are laid with multi.Colored pieces of fabric, because rattling. :-)We look at the inscriptions at the bottom:

OTH was held on August 21, 1956 (or 1957. Inaudible) year. T.E. Not forty, but in the USSR for at least 4 years as radioles are sold, with an electric drive. Anyway.We look at the motor:

The principle of operation is also simple: we start a spring with a handle, the spring pushes the shaft, and through the system of gears the rotation is transmitted to the disc with the plate on it. The most interesting part here is the speed regulator:

The very lever sticks out from above, which is pushed through a wooden panel lever the speed regulator. What happens: from rotation of the drum with a spring inside (in the photo from the back), the horizontal shaft with cargo begins to spin. Under the influence of centrifugal force, weights move away from the axis of rotation and pull the metal tape to which they are attached. The tape, in turn, pulls a disk to the left, which is on the right side of the axis, and when it applies to a lever with a felt block (I don’t know what to call it correctly), the turns are fixed and they no longer increase. When the spring factory ends. The revolutions fall themselves, the weights return to the axis, and the disk is pushed away from the pad.So it goes.

Operation Rules

The device will last a long time if you follow the following recommendations.

To preserve the mechanism in working condition, it is important to monitor the composition of the applied gasoline. It should not have mechanical impurities in it. Before starting repair work, it is necessary to process parts with the same fuel. It is not recommended to use the solvent, as it is able to reduce the elasticity of rubber spare parts, damage the washers. Dry details are best using compressed air purge. Do not clean the small holes, for example, using a needle or wire.

• The final assembly, installation of parts evenly. So you can avoid deformation or bends of parts of the carburetor.
• Make sure that the float camera is tightly connected to the body. The future success lies precisely in their tightness.
• Before starting the mechanism, check how the air filter is connected. It is worth fearing fluid leaks.
• To avoid leakage, the fuel valve must be opened, then block the air damper, the control of the lever is tightly tightened, open the throttle of the throttle by 18-14. The drowner should be squeezed before the appearance of fuel drops (if the temperature decreases to 5 degrees).
• When starting the air damper, you need to open a little. As soon as the motor warms up, open to the full.

How to determine by candle the correctness of the fuel supply system

If you drown out the engine and unscrew the spark plug, you can determine by the state of the electrode and its color how the engine works well.

In Figure 1 and 2: Electrodes are polluted with oil. Causes:

• Too rich mixture (fuel is much larger than air).
• The ignition system works incorrectly.
• Oil penetrates the combustion chamber (either because of the wear of piston rings or valves bushings).

In Fig. 3, 4 and 5 traces of soot are visible, in addition, in rice. 4 and 5 there are signs of a “cold” candle.

• The type of candle is incorrectly chosen (too high the vibal number).
• Too rich a mixture of fuel and air.
• Too strong cooling (rarely).

In Figures 6-24, the electrodes are covered with an extraneous lead raid due to interruptions in the ignition of the working mixture.

Rice. 25-27: Electrodes are burned, the reasons may be in:

• Incorrect selection of candles (low viburnum).
• Poor working mixture.
• Incorrectly installed ignition.
• Too fast combustion of the mixture (manifestation of detonation).
• Overheating of the motor (problems with cooling).

In Fig. 28 and 29 electrodes are overheated and melted. This is due to incorrectly exhibited ignition (too early).

Carburetor adjustment. | Topica author: Mitsue

In order to save the motor during the period of the run.In, the Chinese are reinsured.

Mikhail (Delman) as a simple layman to make a nozzle with lower bandwidth?

Using (ramakrisna) Michael, seal the old jacket tin and drilled the hole less, well, or pick up the jacket suitable, which is more accurate

Mikhail (Delman) https: // www.Wagnerland.Ru/index.PHP? Topic = 602.MSG13410. Here it will be more understandable

Denis (Vishala) Kostya, bend or solder the valve’s foot.

Mikhail (Delman) Another observation: the main nozzle from the VAZ carburetor is ideally suited for KDSHKA carburetors. I’ll go tomorrow, ask the size. I have a diameter in a milimum. In the sprinkle and it can be adjusted if the native is lost

FARID (RATNAMALA) How much revolutions to turn the mixture adjustment screw before the first launch?

Denis (Vishala) Farid, this is a idle screw. Adjustment of the mixture in this carburetor is carried out by the position of the needle and the selection of a jetter.

Sergey (volkert) how to understand 80 cubic meters I bought or 50.

Alexey (Eckehard) to unscrew the candle from the cylinder, insert a straw into the hole and lower the piston into the lower position. Now take a syringe of 20 cubic meters and pour gasoline into a cylinder. You can calculate the bracket)) 49 or no more than 80 exactly but so)))

Marat (AINGEAL) Alexey, I am tormented by vague doubts, if you lower the piston into the lower position and pour gasoline into the cylinder with a syringe, whether gasoline will flow through the exhaust or intake Windows of the cylinder into the exhaust pipe and inside the engine. The 3rd picture shows that the channels are open with the lower arrangement of the piston

Alexey (Eckehard) Marat, logical!! I didn’t think about that))) so the Windows can be drowned, for example with plasticine. I have to spend such a test. The season end then and I’ll see.

Marat (AINGEAL) Alexey, I think it’s easier to find out the diameter and piston stroke, after which I think it will be possible to calculate the volume of the cylinder.

Vladimir (Achelous) Sergey, I’m sorry that I broke without asking, accidentally got to the link. On F80 stilettos of mounting cylinder M8, on 50-ke-m6.

Vladimir (Achelous) Alexey, Alexey, so you pour cubes 200. Through the Windows everything will flow into the crankcase, and then to the muffler!

Vladimir (Achelous) to optimize the carburetor cd, first of all, you need to lower the fuel level in the carburetor. To do this, just disassemble it, unscrew the intake fitting, remove the gasket from under it, and carefully assemble it back. Without laying, the level will decrease to (-10)-(-11) mm.Smell the nozzle with acid with a solder, and blow into it while the solder is melted. An extra solder will fly out, there will be a hole that must be calcined with an ordinary sewing needle with a diameter of 0, 65. 0, 67 mm, pushing it to the middle and stretching back. The excess solder from the extended part of the hole is carefully removed with a hand (manually! ) so as not to damage the actual nozzle, t.E. Calibrated part. The missing ability of such a jacket will become 72-76 ml/min. Full speeds will appear.

Motoblock adjustment

The tuning of the motorogue carburetor is to adjust it. In order to be able to adjust the carburetor without the help of others, it is necessary to take subsequent steps:

• Small and full gas screws must be tightened in full.
• The screws of small and complete gas are unscrewed for one and a half turns (set the throttle in such a position so that the gap of the corresponding size forms between the base and the duct).
• Start the motor and wait until it warms up.
• When working motor, the control lever is put at small speeds.
• Achieve uninterrupted operation of the motor. For this purpose, it is necessary to make the least idle speed using the throttle screw screw.
• Set the idle speed to the maximum using a small gas screw.
• Set the idle speed on as in the cinema using a screw of the throttle.
• Repeat 6 and 7 step until the continuous operation of the motor begins.
• The engine control lever is put on gas.
• If you arise, turn away with a screw that regulates the quality of the consistency, less than 2.4.5 revolutions.

I would like to note that the adjustment of the carburetor on the Neva walk.Behind tractor is performed correctly according to the above annotation. Neva installed on the Neva walk-behind engineer is a single-chamber and horizontal device. The chamber of the float is located in the very center. Throttle. Flat.

On the Neva motornote, the DM-1K engine is used, which is produced at the Red October Neva plant. The manufacturer categorically does not use Chinese.Made engines. This also applies to the production of a motor cultivator.

Gasoline that enters this device does not necessarily contain mechanical impurities. Our client remains only gasoline. The use of the solvent is not allowed, because the elasticity of the washer and rubber parts is damaged.

To dry the details, use the purge of compressed air. It is not recommended to clean the small holes with wire on a different needle. Installation after repair or cleaning should be carried out moderately so that there is no wrist and deformation of the parts.

I will try to summarize and place information from various sources in one place in one place. I apologize to the authors of articles that I do not indicate links to them. I just don’t remember where I got the information. I have not yet claimed 100% reliability of all information, t.To. I draw some conclusions on my own guesses. Perhaps someone will correct me. Let’s practice, together we will create a small instructions for adjusting. Service centers, of course, know everything, but will not share their knowledge. The less information, the more profitable it. After all, Neva has long been released, but there is no literature on repair and commissioning. And it will not. As in my case, they will answer you: “Bring to us”! And if this is another state, or thousands of kilometers to the service workshop, while. I’m not one. I read in different forums, people are interested in how it works and how to establish. Therefore, I’ll try from the simplest. For some, this will be clear and so, but beginners may become clearer.

I just faced the problem of setting up the Neva MB-2 motor block. During operation, wiped the traction of the centrifugal regulator with a rag and the bolt was not much tightened. In general, she turned. After that he tried to establish for a long time, until it succeeds. I will try to describe how I regulated how it works.

I’ll start with a centrifugal regulator. Its purpose is to maintain a constant rotation frequency of the crankshaft of the engine when changing the load on the shaft. T.E. So that the motoblock does not staller when you are past. At the same time, through wheels, gearbox, pulley, belt, engine pulley begins to slow down the engine and, if not for the centrifugal regulator, then the engine stalled. After all, we do not have the opportunity to put pressure more and more on the gas. The design is thought out very competently.

Click in the picture to increase

After the engine has been opened, the weight of the regulator is spinning. They move out at the expense of centrifugal force, opening like a flower, and shifts forward on the rod, turning the regulator lever. Now, if we load the engine, while the rotation of the engine will begin to slow down. At the same time, the speed of rotation of the weights will also decrease, they will begin to fold (hiding behind as a flower) and the regulator lever will begin to return back, which will lead to a turn through the lever of the centrifugal regulator, traction, throttle throttle to increase fuel consumption, t.E. Add gas. T.E. Having put the handle of gas to a certain position, we may now not worry that the engine is stalled when loading. As soon as we reduce the load, the weights diverge again and turn through all the thrusts of the throttle now to reduce gas. In this entire line there is another spring. With an increase in gas, it through the cable and a bracket in the form of the letter “G” is stretched and counteracts the rotation of the throttle valve in the direction of reducing gas.

Click in the picture to increase

Farther. T.To. The revolutions “walk” when opening a completely air damper, then a poor mixture comes out. It is necessary to adjust it. We screw up the correcting screw for the working mixture of idle. Now we unscrew this screw and start the engine for one and a half turns. The device of the carburetor is such that when screwing the screw, we overlap the air channel and increase the amount of gasoline into the engine. T. E. Enrich the mixture, and if we unscrew the screw, then add more air, so we impoverish the mixture. Now, with a completely open air damper, we try to achieve the most stable revolutions, reduce the gas to a minimum and again try to achieve minimally low but stable engine speeds.

Now we look at another important part. A screw of the stop of the throttle. With the conquered gas, it should rest on the carburetor board. Now we smoothly twist it and achieve minimum revolutions. This screw allows the throttle to close to a certain angle. Now you can test the motoblock in the case. Having given it to warm up under load, you can find out by candle whether the working mixture is correctly adjusted. T. To. Having worked at idle, you will not see this.

How to adjust the carburetor on a walk.Behind tractor?

In the technique of different manufacturers, adjusting the carburetor of the motoblock is carried out in different ways. Below, consider how to correctly and accurately configure the fuel nodes in agricultural agents of different brands.

Motoblocks of the brand cascade

The equipment of most branded models of the brand cascade includes KMB-5 carburetors of the brand.

To configure this fuel node, you need:

• Adjustment of the carburetor VAZ 2107 with your own hands

• Drain the remaining fuel from the factory float chamber;
• Open the fitting and start the air inside the fuel node;
• Configure the position of the throttle damnel precisely in such a way that a neat 2-mm gap is gradually forming between it and the air duct located under the barrier;
• Squeeze the bolts responsible for setting the fuel supply;
• Start slowly turn the screws slowly until the power unit is reduced;
• Slowly screw the screws back in turn.

As a result, the user will achieve the elimination of failures when operating the engine and reduce the expenses of the fuel consumed by him.

Motoblocks Neva MB-1 and Neva MB-2

Most often, in the factory design of models MB-1 and MB-2 Neva, K-45 carburetors are provided or their modifications. The order of their setting will be the same.

For factory fuel nodes of the type K-45P, adjustment should be performed as follows:

• First, you need to work to the end of the factory screws designed for your own adjustment of the supply intensity of maximum and minimum gas;
• Then you need to alternately unscrew each of these steel screws;
• Further, the operator will need to start and fully warm up the power unit of the used walk.Behind tractor;
• After that, you will need to adjust the operation of a completely working engine at a minimum possible idle move;
• If necessary, you need to repeat the 2 previous steps. This must be done until the action of the power unit at the minimum possible speed of the standard idle will not become as stable as possible;
• If after several repetitions the result could not be achieved, then the propeller adjustment and installation screw will need to be unscrewed and wrapped back. This procedure will need to be repeated until the motor resumes its work.

If numerous manipulations with a screw for adjustment and installation of full gas did not bring the desired result, then it will be necessary to extract and inspect the carburetor. If necessary, it is necessary to carry out its repair or thorough cleaning.

Motoblocks agro

To configure the standard fuel node in the design of this brand’s models, you need:

• Completely screw the screws that initially be responsible for adjusting the engine operation in small and full gas mode. Immediately after that, each of the screws must be unscrewed by 1.5 turns;
• Run the power unit and wait 10 minutes to heating it;
• Adjust the continuous operation of the built.In engine of the existing walk.Behind tractor directly at the minimum permissible idle speed. The operator must begin to turn the screw for independent adjustment of the position of the standard throttle damnly in different directions directly until the work of the ICE is as quiet and stable as possible;
• Configure the amount of fuel and absorbed air, which are supplied to the float metal chamber of the carburetor and engine cylinder. The gradual tightening of the screw will lead to the enrichment of fuel with absorbed air in the factory metal float chamber. Its slow twisting, on the contrary, will contribute to an increase in the amount of air, which is supplied directly to the cylinder. In more detail about setting up the carburetor of the Motobobok Agro will tell the video.

It is necessary to configure the carburetor of the agro motor unit when extraneous sounds appear from the motor, as well as with an increase in the volume of the consumed fuel and the formed exhaust gases. Timely adjustment of the node with your own hands will improve the quality of fuel, which will lead to an increase in the power and efficiency of the power unit.

Motoblocks MTZ-09

To configure the carburetor of the Belarus Motoboblock carburetor if its engine does not gain or does not support the required speed. You need to adjust the fuel node before the start of the season.

The procedure should be like this:

• First, it will be necessary to completely screw the bolts that regulate the supply of small and created full gas. Immediately after that, metal screws must be unscrewed by 1.5 revolutions;
• Further, the force of adjustment of the power unit will need to be transferred to a minimum full.Time position. At the same time, it is important to make sure that the motor does not stall;
• At the end, it remains to put the adjusting screw to that factory position in which a sufficient amount of air will fall into the fuel node.

A standard small gas settings screw is initially required to adjust and install the maximum created revolutions of the working motor during its functioning at idle. Manipulations with this bolt allow the operator to install a built.In throttle flap directly to the position in which the gasoline power unit will work as stable as possible, consuming the amount of fuel specified by the manufacturer.

Motobobes bee

The need for urgent adjustment of the built.In carburetor of the brand of the bee brand will tell you problems with the launch of its engine, as well as a significant increase in the volume of fuel consumed by it. Before setting up the fuel unit setting up, it is necessary to remove and clean the agricultural filter, inspect and, if necessary, blow the fuel supply channels, and also clean the spark plug.

During your handwritten tuning of the carburetor, the existing motorblock is needed:

• Screw the screws of independent setting of small and adjusting the full gas created to the very end;
• Set a regular lever of speed switching to a minimum allowable position;
• To expose the minimum created revolutions of a standard working engine in which it will function steadily and without any extraneous sounds;
• Adjust the maximum permissible working revolutions of the built.In ICE in idle operation, using a built.In screw for supplying small gas for this. As a result of the power unit of the existing walk.Behind tract, it should begin to work as stably as possible;
• Drown out the motor and start it again to check the settings results.

Subtle setting: weights and springs

The setting of weights begins after that. This is already called the thin adjustment of the trambler. In this case, the UZ is set up, for which the proofreaders are directly responsible. CNTR and VK.

The first, centrifugal regulator contains two weights and two springs. When rotating the distribution rotor, weights under the influence of the Central Executive Committee diverge from the sides. In the process of this, a shaft with fists or a curtain is shifted (if the ignition system is contactless). Thus, contacts are triggered noticeably earlier.

Two springs act as counteraction to the Central Executive Committee, on which the effective functioning of the entire ignition system depends. The springs themselves are different, and this is done so for a reason.

Revolutionary revolutions on the Neva motorblock

The adjustment of the motorogue carburetor should be carried out at times with the aim of working mechanism for good operation. A probable prerequisite for the differences during the operation of the motor block is a carburetor. For this purpose, the device is disassembled, cleaned and regulated (set up). Regardless of the carburetor brand and how much you can choose the studio, on which device it is installed, the principle of regulation for all a monotonous. The difference you will like more exclusively among the revolutions.

Where it is necessary to find out at one time the interruption of the motor? When the carburetor malfunction appears, the most important thing is to check the fullness of the fuel tank and the oil level. If the fuel and the oils are enough, then they run to the examination of the candle. For this purpose, it is twisted and using the ignition inspects the spark. Then they test the flow of gasoline to the carburetor. For this purpose, the hose is removed from the fitting and tracking the intake of fuel. If the fuel does not appear, then most likely it will be necessary to clean the filter mesh. For this purpose, the fuel tap is unscrewed by all parts are washed with gasoline. The same is done with the potpel jacket.

The carburetor is cleaned in this way. To clean the device, first of all, it must be removed. In order to easily remove the carburetor, it is necessary to closely look around the body of the device and unscrew the details to our client where it holds.

What will be needed, remove the carburetor and pour gasoline with it with its use. We carefully separate what remains our client of the device parts (nozzle, float) for the upcoming purge and cleaning. This manipulation is performed by a special cleaner.

With strong contamination, use the compressor.

After cleaning, we painstakingly dry the details of our client and boldly proceed to the assembly. After assembly, adjust the carburetor for the walk.Behind tractor.

I would like to note that the adjustment of the carburetor on the Neva walk.Behind tractor is performed correctly according to the above annotation. Neva installed on the Neva walk-behind engineer is a single-chamber and horizontal device. The chamber of the float is located in the very center. Throttle. Flat.

In the process of this, a shaft with fists or a curtain is shifted (if the ignition system is contactless). Thus, contacts are triggered noticeably earlier.

Two springs act as counteraction to the Central Executive Committee, on which the effective functioning of the entire ignition system depends. The springs themselves are different, and this is done so for a reason.

• The first spring is longer, it is responsible for the moment of entering into the case of the TsNTR of the regulator carrying out the tension. At the same time, this spring regulates the right angle up to 1.2 thousand. Revolutions per minute, ensuring stiffness.
• The second spring is shorter, but it is much tougher than the first. Corrects the moment of the break, providing free move.

Experts insist that the second spring should be ensured by free move. However, some motorists believe that from this there is an unstable operation of the internal combustion engine at low speeds. It is supposedly adjusted by a stretch of this spring.

As for VK or vacuum corrector, it contributes to the occurrence of ahead of the first chamber. In other words, when it comes to partial load on the power plant.

This itself can be created by this advance regulator at either large speeds or under loads. This should be understood. Yes, and at xx, by the way, too.

Video below about the work of weights on a trambler

Adjustment of the fuel system of the walk.Behind

If the fuel is not supplied to the cylinder, then, first of all, it is necessary to check if the fuel is filled in the tank. It is also necessary to control whether it enters the carburetor. To do this, the hose is removed from the input fitting of the device. If we are talking about a carburetor of the type K45, it should be pressed on its quencher so that the fuel begins to pour out through the drainage hole.

If the fuel does not get into the carburetor, then you need to unscrew the fuel supply valve, completely disassemble it and remove the clusters of the dirt from the mechanical cleaning filter. To achieve maximum cleanliness, all components must be treated with gasoline. The fuel valve is collected and returned to its former place.

If the fuel enters the carburetor, but is not supplied to the cylinders, it is necessary to check the correctness of the fuel valve, as well as the presence of dirt on nozzles.

Motoboblock adjustment: carburetor, valve, fuel system

This article describes the adjustment of the walk.Behind tractor, namely its main parts: carburetor, valves and the fuel system. The process is not easy, so we also attached several photos and videos.

The instability of the engine engine speed says that the carburetor needs to be adjusted. The need to perform this procedure, as a rule, occurs before the start of the agricultural season, when the equipment was not used for a long time, or after it, when the walk.Behind tractor was subjected to significant loads for a long period of time.Before starting adjustment, it is necessary to warm up the engine. Directly, the process of work is as follows:

• The screws that regulate small and maximum gas are injected completely, after which they are weakened by about one and a half turnover.
• The motor starts and warms up for about 10 minutes.
• The lever that controls the operation of the power plant should be installed in a minimum position, but the engine should not stop.
• The screw that regulates the throttle of the throttle will help adjust the minimum speed at idle so that the engine’s work is stable, without extraneous noise and stops.
• Rotation of the screws makes it possible to accurately set the amount of the combustible mixture that enters the motor.
• Tighten the screw helps to enrich the mixture, while it is twisting, on the contrary, increases the volume of air entering the engine;

With the help of a small gas screw, the maximum speed at idle should be adjusted. Similarly, it should be done with minimal turns, using the screw of the throttle of the throttle. The essence of such an adjustment is that the shaft screw allows you to adjust the angle to which it is closed;

The lever responsible for controlling the engine should be transferred to the position of “gas”. If the work of the walk-behind tractor still cannot be called stable, the full gas screw is regulated until the perfect move is observed. Nevertheless, the maximum permissible number of screw revolutions is 2.5.

The accuracy of adjusting the carburetor can be determined by what the spark plug looks like after a short work under load. If the working mixture is ideal, then there will be neither a carrier nor traces of fuel on the candle, which speak of too poor, or, on the contrary, too rich combustible mixture. However, it is necessary to notice that the soot or traces of fuel on the candle can talk not only about incorrect adjustment, but also about more serious problems of the walk.Behind tract, among which a faulty ignition or cooling system.

Over time, with significant loads, the gap of the motor block engine changes. The reason for this may consist of wear of details. The insufficient distance leads to the fact that the stages of gas distribution are significantly changing, as a result of which it is not possible to achieve a sufficient degree of compression, the power plant works with interruptions and does not go to the declared power. In particularly serious situations, even deformation of the valves can be observed. If the gap is too large, then significant mechanical noises are fixed, the gas distribution phases also change significantly, the valves open for too short time, which is why the cylinder is not filled properly, the power drops, failures occur. The adjustment of the gaps is necessary as soon as the engine operation has become incorrect or occur with a significant noise. Ideally, the engine on which the adjustment should be cooled.

So, first you need to get to the flywheel. It is on this detail that the value of the upper dead point is noted. The flywheel is hidden under the casing, and therefore you have to remove it. Before removing the casing, an oil filter oil bath is removed. You can facilitate the task in the process of removing the casing if you fix all the latches with elastic bands. All bolted joints are spinning the key, after which the cover is removed without problems.

On the flywheel you can see the marks that indicate the VMT, as well as values ​​of 5, 10 and 20 degrees. The mark of 20 degrees indicates the injection of the combustible mixture. The flywheel should be brought under the upper dead point, focusing on the corresponding division. The valve cover is untwisted and removed.

In the process of adjustment, you need to use the following tools:

According to the technical passport, the gap of the valves of the engine of the motor block is from 0.1 to 0.15 millimeters, and therefore with the help of the blade you can adjust it very accurately. However, you need to pay attention to the fact that some blades have a thickness of 0.8 millimeters, which is unacceptable. The exact value can be recognized by a micrometer or from information on the manufacturer’s website. Adjustment is as follows:

• Screwdriver;
• We relax the nut, insert the blade and begin to squeeze;
• You should FOCUS on the blade, gently pulling the nut;
• Adjustment is carried out until the free valve move is eliminated. He must sit tight enough.
• In the reverse order we collect the casing, install an oil bath in place.

If all manipulations are carried out without errors, then the engine will work exactly and without unnecessary noise.

Adjustment of the fuel system of the walk.Behind

If the fuel is not supplied to the cylinder, then, first of all, it is necessary to check if the fuel is filled in the tank. It is also necessary to control whether it enters the carburetor. To do this, the hose is removed from the input fitting of the device. If we are talking about a carburetor of the type K45, it should be pressed on its quencher so that the fuel begins to pour out through the drainage hole.

If the fuel does not get into the carburetor, then you need to unscrew the fuel supply valve, completely disassemble it and remove the clusters of the dirt from the mechanical cleaning filter. To achieve maximum cleanliness, all components must be treated with gasoline. The fuel valve is collected and returned to its former place.

If the fuel enters the carburetor, but is not supplied to the cylinders, it is necessary to check the correctness of the fuel valve, as well as the presence of dirt on nozzles.

To deal with the carburetor of a gasoline motor block like KMB-5, it is necessary to remove it from the motor and pour the fuel from the float chamber. Through the fitting (see the drawing), with which gasoline is supplied, it is necessary to submit an air mixture, after installing the carburetor in the working position. Air passage should go unhindered, and when a carburetor is coupled, it is completely to stop. These features indicate the full performance of the part.

Details in the figure: 1. Fitting, supplying fuel; 2. Upper body; 3. Throttle shutter; 4. Small gas needle; 5. Nozzle; 6. Lower body; 7. Air damper; 8. A screw fixing the screed; 9. Maximum gas needle; 10. Spraying element; 11. Float; 12. Fuel supply valve.

The fuel level inside the float chamber can be adjusted using a float tongue. Ideally, it should vary from 3 to 3.5 centimeters.

To perform the purge of the nozzles, it is necessary to turn out the screws responsible for the full and small gas.Cleaning the parts of the carburetor begins to turn off the screws holding the upper body. The lower case is removed, the fuel supply valve is washed with gasoline, and the dirt from the nozzles is blown away by the pump. It is necessary to check whether the float is intact. You can’t use a rag in the process of cleaning.

After the cleaning is completed, the case is connected. It is necessary to control the spray pipe clearly goes into the hole located on the upper body. Open the throttle flap and check how clearly the assembly is completed. Screws fixing the upper body are tightly twisted. After the assembly process is completely completed, the carburetor should be adjusted. This will significantly improve the performance of the walk.Behind engineer with attachments, since the correct work requires perfect setting up all its parts.

If the carburetor DM 1 is installed on the motor block engine.08.100, then the methodology for its adjustment will be this:

• Wrap the screw 10 (rice. 3) small gas until complete and turn away from yourself by half a turn.
• Then you need to tighten the screw 9 of the full gas completely unscrew it by 2 turns.
• Unscrew the screw 4 (rice. 4) the minimum engine speeds right to the stop of the lever in the tide of the carburetor case and wrap for 2 revolutions.
• Get the engine of the walk.Behind tractor, then adjust the stable work at maximum speed after warming up 9.

Do not allow turning off the engine control lever, transfer it to the minimum gas (revolutions) position and by turning the screw 10, set stable small gas revolutions.

That’s basically it. The main points of adjusting the main parts of the walk.Behind tractor are considered. Adjust your walk.Behind tractor with pleasure!
