How to disassemble the gearbox of the Champion motor cultivator. Operating advice

The device and subtleties of the operation of the cultivator gearbox

The gearbox for the cultivator is no less important than the engine or working parts. The widespread opinion that this is just a passing detail is completely incorrect. Consider which criteria it is better to choose a gearbox for a motor.cultivator and how to use it correctly.

The soil plays the soil that has to be processed to be processed when choosing this element. So, a chain gearbox, like a worm, manifest themselves well on light earth. chernozem and sandstone.

If the site is composed of heavy loams, all the more full.fledged clay, it is recommended to choose between chain and gear devices.

The worm version is suitable only for lightweight and especially light cultivators, which will cultivate well-groomed areas up to 6-8 acres. This method of energy transmission occurs due to the clutch of the screw with a wheel covered with teeth of a special profile. When the worm rotates (the so.called screw), the thread moves along its axis. In the same direction, the teeth are also pushed simultaneously. The main part of the wheel is spinning, and the milling cutter is obtained from it.

The main properties of this design are:

• smooth movement of the cultivator;
• weak noise;
• saving funds;
• small efficiency;
• Excessive heating and powerful carbon fumes;
• small resource;
• the inability to use the reversal mode and additives of hinged components.

Most cultivators of the latest models use chain gearboxes. Their simplicity is considered an important advantage. There is only a chain and a pair of stars: one below (mounted on a shaft), and the other at the top.

It is worth remembering that chain gearboxes can be non.vegetable, they are used if there are no more than 15 acres to be treated for plots. In this case, the resource of the device may exceed 10 years.

Even experts cannot call obvious minuses of the chain gearbox. But his advantages are obvious:

• minimum energy loss between the motor and cutters;
• affordable price;
• relatively narrow case;
• simple maintenance;
• the ability to back.

If reliability is in the first place, it is worth giving preference to a gear structure.

In most cases, it includes from 3 to 5 gears in a closed, but amenable of disassembly of the body. Such devices show themselves very well in heavy.class cultivators. They are used even in motoblocks designed for the cultivation of land with an area of ​​over 25 acres. But it is important to understand that the cost of gear gearboxes is very high.

How to disassemble?

Lubricate the gearbox as thoroughly as possible. Even noise can be eliminated if the deficiency of lubricants can be replenished. But you should be approached as carefully as possible to the choice of a suitable lubrication brand, the use of contaminated compositions is unacceptable.

It should be borne in mind that extraneous sounds are often associated with poor tightening fasteners, with wear of bearings and gears. To make out the gearbox, you need:

• remove it;
• unscrew the screws;
• remove protective caps;
• stretch the sleeve of the output shaft;
• disconnect the lever, and then a fork;
• take out the primary shaft (in a tight bundle with gears);
• extract the bushings of the shaft and chains;
• dismantle the block of shaft and stars;
• Delete the intermediate shaft and gears;
• Remove the coupling, half ahead (assembly is carried out in the reverse order).

What are the breakdowns?

Most of the problems in the gearbox of a motor block arise due to overload. Such breakdowns include the sleeve of the bushings on the metal chain, which leads to the so.called “slip”. Also, the owners of the motoblocks very often discover interrupted bushings switching. In order to avoid such troubles, experienced owners advise switching speeds only during a complete stop of equipment, in no case on the go. In addition, a star break is considered to be a common occurrence. That is, factory welding is not enough for the star to withstand overload.

It is very simple to “get out” from this annoying situation, you just need to return the star to its original position and grab it with welding much better. Side loads lead to wear of the support washer, after which there is a fly from the bushings from the chain. In addition to all of the above, it is necessary to periodically check the oil level in the gearbox, as well as to replace it.

How to check the oil in the motorblock gearbox?

Track the amount of oil to monitor constantly. Otherwise, a negligent attitude to technology will lead to fatal consequences. Fresh oil is poured every 50 hours. Along with this, excessive loads should be avoided, which ultimately lead to quick production of mechanisms and components. Let’s move directly to the change of oil:

• Install equipment on a flat area. Find a probe 70 cm long.
• The probe bends and is pushed into the opening for the filling of the oil to the stop, after which we take out the rod.
• Observe the level of oil, which should be at least 25 cm. 2 liters of oil are added to a dry gearbox, a minimum of 1.5 liters.

Pully oil should be Gostovsky. It is pointless to use cheap oil, because sooner or later, it will cause breakdowns inside the motor block gearbox.

What are the gearboxes for the walk.behind tractor

They all find their use on motoblocks of different types.

Angular

The angular gearbox for the walk.behind tractor provides an docking of the engine with a transmission and a hinged mechanism. Another device is used if it is finalized. The corner device consists of the following parts:

• flange;
• flange mount;
• bearing;
• frame;
• pulley;
• belt;
• the washer made of steel;
• pulley mount;
• key;
• Rotor shaft.

This device can be made independently. Before work, it is necessary to take into account the conditions in which he will work. These are radial and axial loads at the ends of the shafts. The load depends on the type of lubricant and temperature. The case is best chosen by the factory manufacturing. For the shaft, bearings of the desired size are selected.

Reducing

Reducing gearbox for a walk.behind engineer, created or industrial manufacturing with your own hands, is designed to increase the power of the agricultural unit. This may be needed when working on a walk.in on sandy ground, when the wheels begin to slip. It is used on gasoline and diesel technique equipped with a system of air cooling.

You can reduce the number of revolutions and increase the power of the drive mechanism with the help of lowering gear reducers, which are sometimes called howls for a walk.behind tractor. They are considered the most reliable for the work of a diesel or gasoline walk.behind engine that has air cooling. When operating the unit, a decrease in the number of revolutions occurs. This allows you to use a single.axle tractor for especially hard work, for example, for plowing heavy soil or harvesting potatoes using potato.cutting.

Gear

A gear transducer with a differential is used in heavy.class motor blocks. It is well suited to engines in which the crankshaft is located vertically. The gearbox publishes little noise during operation, has high performance. It is able to function in straight and angular schemes. Gears are used both conical and cylindrical. The device requires the constant presence of oil in the crankcase, but this feature is compensated by its high power.

On heavy units, a gear converter is often equipped with a gearbox. This transmission allows you to move in reverse. Reverse occurs during the reverse rotation of the gears in the case. This is achieved by a change in the position of the lever outside the body.

Gear gearbox is the best choice for heavy agricultural machinery. The engine equipped with this mechanism operates longer than with a worm version.

Worm

The worm gearbox is widely used in the set of mini-tractors and motoblocks. This model has gained popularity due to the long period of trouble.free work and high reliability. A worm type device has a reverse that allows the aggregate to move reverse. A distinctive feature of this converter is the presence of a special screw and worm wheel. The profile of the threads on the details. the trapezoidal. They are made from materials of increased strength.

The screw can have a four.set thread or two.stroke. It coincides with the thread on the gear. Teeth on high.quality details are made of antifriction steel. The effectiveness of the device is high. Its advantages:

• The gearbox allows you to extend the life of the engine;
• creates little noise during work;
• The device of only 2 parts consists;
• has a large transfer number;
• has a smooth move;
• High effect of self.molestation.

All positive qualities appear with accurate assembly and adjustment of the mechanism.

Chain

The chain device in its design necessarily has a chain. Sometimes it is not one, but in the amount of several pieces. The gearbox chain is put on stars and ensures their scrolling. The device is convenient in operation, has a reverse function and a high degree of reliability. The principle of operation is similar to the belt mechanism. Change the gear ratio is easy to replace the sizes of stars. They work like in a bicycle, but vice versa: the small one is leading, and a large one is a led star.

The reliability of the work is provided by the quality of the metal of the stars and the strength of the chain. With self.manufacture of the gearbox, motorcycle stars should be taken, they are much stronger than bicycle. The device of the product is simple and reliable, has a reverse. The chain requires constant lubrication and suspension. Its gap is a common cause of gearal breakdown. For repair, you need to change the chain.

Combined

The combined gearbox combines the toothed and worm, worm and cylindrical transfers. It is single.stage or multi.stage. A single.stage mechanism has a gear ratio up to 7. The case is made of cast cast iron or welded from aluminum. Two.stage devices have a transfer number up to 40, three.stage. up to 150.

All of them are designed to change the speed of rotation of engine shafts and power selection shaft. All types of gears are placed in a single building. The combined mechanism is the most practical. With small sizes, it has high qualities and low cost.

Madoor

Clutching the wheels of the earth.processing machine with the soil can be strengthened if you use soil.bearing or a motorized carrier for a walk.behind tractor. The driver is one of the attachments. It makes it possible to reduce the speed of the agricultural unit and increase the traction force along with the torque. The analogue of the gearbox works with a chain and stars on the shafts. If desired, this device can be made with your own hands. Details are used from other equipment.

Each considered converter is endowed with its shortcomings. To minimize their number, you should try to make the device yourself. A homemade thing can become a better and more convenient in operation than a purchased copy.

DIY maintenance and repair

Timely maintenance will provide long and trouble.free operation of the cultivator.

The products of the lineup are not unified by 100% by nodes and mechanisms. In the design of cultivators are used:

• 2 and 4-stroke engines with a horizontal and vertical location of the crankshaft;
• clutch friction and craft mechanisms;
• worm, wedge.repair, chain gearboxes.

In such a situation, the main assistant to the owner in servicing the machine is the instruction for the operation of a particular unit, which gives all the necessary recommendations.

As an example: the regulations for maintenance of the easy cultivator Champion GC 243.

With the independent repair of the cultivator, critically evaluate your skills and the presence of the necessary tool. It is advisable to entrust the specialists of service centers to the diagnostics and restoration of the gas.somnicor performance, the gearbox.

Problems and ways to eliminate them

If during the operation of the device, the summer resident notices increased noise in the gearbox, it is worth immediately stopping the work of the cultivator:

First you need to establish the cause of such a phenomenon. Experts say that noise in the gearbox arises due to a lack of oil. Also, a similar problem can be caused by the mismatch of the quality of the used oil according to its brand and cleanliness. For example, if an inexperienced farmer flooded the old gasoline or fuel of dubious quality into the fuel tank of the unit. In the first case, you should just add the oil to the cultivator gearbox to the optimal level. In the second. to change his brand;

The nodes of transmission can also make noise. This is due to low-quality tightening of fasteners. Carefully inspect the device and tighten them if necessary;

In many cases, noise is generated by worn gears and bearings. If the reason is this, the farmer should be afraid of more serious breakdowns. However, there will be no problems with the device if the repair of the cultivator gearbox is carried out in a timely manner. And it consists in dismantling and replacing the details that became unusable.

If the soil processing technique does not turn on at all, if its arbitrary shutdown or speed switching is accompanied by difficulties, the farmer should think about the following reasons:

The details that participate in the process of switching speeds could be worn out. Often, similar wear occurs with the ends of the inclined gears, which leads to problems when changing the speed of the machine. In such conditions, it will be necessary to dismantle the worm gearbox of the cultivator and the editing of the teeth of the gears by grinding. If the wear is irreversible, these details of the device must be replaced;

• The wear of the shafts of the shafts could occur or the shafts in the axial direction were shifted in connection with the abrasion of bearings and stop rings. To adjust the axial position of the shafts, it is necessary to install additional locking rings. If the wear of the bearings and rings is too strong, they should be replaced;
• The farmer allowed incorrect clutch regulation, which can lead to the difficulties of gear shifting. This can happen due to the inexperience of the operator, which in advance releases the clutch lever when switching gear. In this situation, you will need to adjust the clutch and learn the correct and timely switching of the transmission.

If the transmission nodes are overheated, it is worth checking the bearings for the degree of their wear. Also, the cause of such problems can be an insufficient amount of transmission oil in crankcases, as well as its low quality. In such conditions, the main repair measures for the processing of land will be as follows:

If a chatter.cooked gear is installed on the product for processing the Earth, and the farmer noticed the oil leak from this node, then he should check the seals of the bearing nodes for the correct installation.

Let’s summarize

The cultivator gearbox is a complex node that can be worm or chain. Its features should be taken into account by the farmer during its operation. You need to understand when it is worth replacing oil or using such a tool as lubrication of the cultivator gearbox, otherwise you cannot avoid breakdowns. The next video will talk about how to correctly repair the chain gearbox of the cultivator with your own hands.

Self.repair of the gearbox

The need to repair a gear biablip gearbox can occur for various reasons. The procedure for eliminating most malfunctions is extremely simple, does not require any special knowledge and skills. In most cases, the repair of the product passes through the standard algorithm:

• Drain the oil is carried out with the subsequent cleaning of the node from pollution.
• The cast.iron or other type of converter is disassembled, each part is inspected for damage, defects, excessive wear.
• If problematic elements are detected, they will need to be replaced with new.
• The device is assembled, the oil changes.

There are several typical problems that are most common among this kind of technique. First of all, this is a failure in sliding clutch, which is eliminated by replacing the spring and disks. If the device begins to issue significant noise during operation, most likely immediate replacement of oil, a gear mechanism is required.

How to change oil in a mechanism

One of the most important factors affecting the service life of the gearbox of various types is the presence of oil. It needs to be changed regularly, which will avoid most problems. To do this, adhere to the simplest instructions:

• Place the gearbox in the working position under a slight slope.
• Exercise control of the oil level. Normal indicators are 25-30 cm probe.
• Place the one.axle tractor on the elevation, and then unscrew the cork on the body.
• Wait for the complete drain of the oil into the container, pour the new with the help of the corresponding hole.

For operation, the products of most well-known manufacturers are suitable, as well as any other oil that corresponds to GOST-17479.

How to change the oil seal

Motoboglok owners often have to deal with a breakdown of oil seals. a simple malfunction that can be quickly eliminated. This will need to be performed by a number of simple manipulations:

Timely implementation of such a procedure is extremely important for the correct operation of the unit, since the malfunction of the oil seal leads to intensive flowing of oil, which can lead to more serious problems.

We disassemble the gearbox of the motorblock Tarpan

Details: Repair of the Tarpan gearbox with your own hands from a real master for Olenord.com.

About idle on a new motor. described his solution to the problem. On the lafan, idle idle speeds are different. the knives rotate.

• A modernized Tarpan with an old tarpan handle and a direct coupling. Pay attention to the gap between the brake and the handle, without removing the head. the brake cannot be removed or turned over, a very limited range of adjustments.
• Rolled gender (2nd lies with add.wheels), I rack my head how to straighten out.

They probably have them from plasticine.There are no such signs on my.Although, on my blades with a stiffener. The thickness of the metal looks like yours.

CSPIRIT wrote: Pay attention to the gap between the brake and the handle, without removing your head. you can’t remove the brake or turn over,

What else do you have?I calmly take mine down, and no problems.Outwardly similar, so.

Would be from plasticine. I would have straightened up. If you read the posts above, here the result of crossing the parts of the early Tarpan (with an ant) ​​with the bought Lifan engine and a gearbox from the new Tarpan. Photos for a deeply respected colleague, shows that it turns out that it will turn out as a result of replacing the oblique trailer on the early tarpan with BS with a direct, without replacing control handles (unless of course they have such (this is 1994 release). On modern Tarpan, the design of the bracket pens is different. there are no problems with pulling out. The details of the early Tarpan are used here. at the other end of the brake. a flat hip, when working on cutters. it is at the top, during transportation. below, like a platform, so that the trunk does not break through. In 1994, Tarpan was regularly equipped with guns for the full cycle of planting potatoes according to Dutch technology (in high beds), hence the brake with a flat cigarette light (if you turn it over), eared cake, a set of milling, gender, limiters, there were no only a dial.

There are discussions about Tarpan on the forumhouse, if anyone is interested in typing this “Cultivator Tarpan (Tula). a full report for a year of ownership with a photo”

Everything was not enough to read patience. Therefore, forgive it if the question is repeated. First: I plan to stick a rotary plate on the trigger. When turning at 90 degrees, it will be pressed to the handle. Has the right to life? Second: W30 oil is recommended to the motor, which I always forget to buy. Is it possible to use 10W40 oil (including on a trimmer), which is always in the car? And is it possible half.skein instead of mineral water?

Rie. Think for yourself, sa30 is summer, and if you operated MK and in winter. I have a 10W30 with the beginning of operation mineral. According to the instructions, the oil is changed to a heated engine. Just do not tip over the engine towards the filter, the oil can get into it. I usually shoot the filter, for one and cleaning it.

[Quote = Rie; 5232052] everything was not enough to read patience. Therefore, I ask you to forgive if the question is repeated. First: I plan to stick a rotary plate on the trigger. When turning at 90 degrees, it will be pressed to the handle. Has the right to life? Take a closer look at the MB-1 MOTOB block gas control handle, it’s not very expensive, but it’s much more convenient for the full-time invention of Tula masters. I set it myself. I did not regret it, showed itself a very convenient device.

Good afternoon, Tarpanovodov. There is absolutely no time to dig a site and topic, so sorry if such a question has already been covered here. And my problem is in the next. there was noise from the adhesion and gearbox. Removed the power unit. the clutch is normal. I dismantled the gearbox crankcase. the gearbox itself is alive and without signs of wear, I check the oil, I change every season. But the clutch drum is playing. The lower bearing of the worm without a backlash, there is a small backlash in the upper, but the drum dangles seriously and noise specifically if it twirling it with your hand. Apparently, there is also a third bearing under the drum. I could not pull out the worm and remove the clutch drum. I turn to you with this, tell me who had such experience. how to make out this knot ?

Everything is just understanding there.First, the drum is removed, then the lower part of the gearbox body is unscrewed and everything is pulled out.There are no additional fasteners there. On the worm there are two 205 bearing and two on the wheel and all.

If you have saved the operating manual, then everything is drawn in detail there.

Thank you, understand you. Found the same manual on Tarpan. There, in the drawing, the drum is screwed to the worm with a bolt or nut, and I have everything in that place in welding. And in this form and bought it new in the store. Chinese or something ? Apparently, the drum itself needs to be twisted and I do not understand how to do it without a special key or puller ?

I don’t remember exactly, I have been sorting out for a long time, it seems a nut there. How can you twist it now? Except on the weld to gently pose a drill.Similarly, sometimes I analyze the sterful.

Interesting photo of such a miracle.Maybe we’ll offer something else.

Victor K. I could not upload a drum photo here. Only on YouTube. Here is the link “

So I understand that you need to twist the drum itself like a nut. And for this you will have to fix the worm, t.e. collect everything back, otherwise everyone will turn. And then a hammer on a drum through a gap. It seemed that the backlash not only the bearing itself is inside, but also its seat in the gearbox body. There is a new bearing. But how to compact his landing in the gearbox crankcase so that he does not hang out on the outer clip ?

2Z wrote: So I understand that you need to twist the drum itself like a nut.

The video is hardly visible (sorinka), but nothing is welded there and the shaft is visible.Most likely a dense landing, and rusted. Carefully look at whether you can see the venerable groove.If the shaft is not screwed and there is a groove, then it will not work.Drip a little WD-40 or brake fluid and let stand for a day.Try to take off. It will not work, then a more radical method, heating the connection (without fanaticism).It is enough to warm up a burner of degrees up to 150-200 (a change in the color of the metal) and immediately try to remove. If there is no puller, then try to knock out the shaft through the copper (other soft metal) entry. Again without fanaticism.

Common breakdown of cultivators “Champion”

Earthwork requires a lot of effort. The cultivator will become an indispensable assistant during soil processing. Depending on the model, the device can loosen and weed out the ground, remove weeds and promote the movement of fertilizers. Today, such a specialized technique from the brand “Champion” has proven itself. The equipment of this brand is reliable and affordable cost. True, malfunctions happen to any unit, so it is important to know about common breakdowns and how not to make a mistake, acquiring spare parts for cultivators “Champion”.

The working elements of the cultivator during operation are subjected to a lot of load, so it is important to conduct a timely inspection of the equipment in a timely manner. First of all, it is important to set up the fuel pump and the equipment ignition system, also check the transmission.

Among the main malfunctions of the technique can be distinguished:

Engine problems. The internal combustion motor starts up, and then turns off or does not turn on at all. The reason may be hidden in the air filter pollution, the starter breakdown or deterioration of the piston system. We can talk about unrelated speeds of an electric motor. In this case, the serviceability of the throttle cable and power regulator should be checked. A similar problem can also be found in electrical cultivators. It is important to check the integrity of the power cable. Also, a malfunction of the electric motor cannot be excluded.

Malfunctions due to problems with the gearbox. The equipment is very noisy. This may indicate a shortage of oil mixture. Strong noise may happen due to insufficient fixation of bolts. Many users are faced with oil flowing from the gearbox with improper installation and wear of the oil seals.

The mill does not rotate. If this problem has arisen in a motor cultivator, then we can talk about the wear of the gear wheels of the gearbox or the torn drive belt. In other cases, the reason lies in the malfunction of the drive elements.

Frequent breakdowns in cultivators can occur due to the fault of the owner. The equipment can work for a long time without a break, which is the cause of overheating and deterioration of parts.

Repair and purchase of spare parts for the cultivator “Champion”

For a long service life of cultivators, it is important to carry out regular diagnostics, check the strength of fixing fasteners and change the oil in a timely manner. With non.compliance with key rules, the unit will often fail. If there is a malfunction and the purchase of spare parts is required, then it is better to search on reliable sites. In addition, complex repair and elimination of problems requires great experience from a specialist, as well as the presence of your own workshop and modern equipment. Therefore, when choosing a website of the service center, you need to be more careful and choose highly qualified professionals. This will significantly save time and money

One of the official representatives of well.known brands is AgroTechService, which allows you to get spare parts directly from manufacturers and at a very affordable price.

Many farmers try to independently repair the cultivator. Of course, the change of oil or gaskets is easy to perform. But if it comes to complex repairs, it is better to seek help from specialists. They will be able to find out and eliminate the cause of the malfunction, conduct a technical inspection and select the necessary details.

Do.it.yourself motoblock repair

Most models consist of the same details, therefore, repair of the main components can be carried out with your own hands.

Standard drawing of a walk.behind tractor

Each single tractor consists of a base frame, a gasoline or diesel engine, a fuel tank, a rotor for fastening milling, wheels and a bracket for fixing the attachment equipment. The most important component is, of course, the engine, on the successful operation of which the operation of the equipment will depend (Figure 1). In addition, modern models have systems for supplying fuel, cooling, ignition and distribution of gases, and the occurrence of malfunctions in them can also lead to stopping the operation of the unit.

Principle of operation

The main function of the walk.behind tract is the loosening of the soil using special mills that are attached to the device frame.

Note: Unlike an ordinary plow, the milling cutter does not turn the soil and prevents the formation of soil erosion.

In addition, the equipment can be used to loosen a row in the process of growing agrarian crops, and special nozzles are useful to collect the crop. Simple models (cultivators) consist of several wheels and handles that are used to control the equipment. On the handles are the necessary buttons to control. powerful and modern models are mini-tractors without a cabin. In this case, control is carried out by buttons and pedals located on the dashboard.

Varieties of motoblocks

Despite the fact that motoblocks are produced by a wide variety of manufacturers, it is customary to divide all such equipment into types depending on weight and power (Figure 2).

According to this criterion, motoblocks are:

The main types of equipment and attachment equipment

As a rule, all types of equipment supply an internal combustion engine with a capacity of 1.5 to 10 horsepower. This is necessary so that even an ultra.light model successfully copes with the loosening of the soil in areas with heavy and dense soils.

The main causes of the motoblock malfunction

Since the main detail of any equipment is the engine, the main number of breakdowns is associated with it (Figure 3). In some cases, poor motor operation may be associated with poor.quality fuel or air filter contamination. There are also cases that the engine works incorrectly due to insufficient heating, failures in the ignition system, carburetor or piston.

The main parts of the engine

We will try to figure out the main types of breakdown of the walk.behind tractor that can be eliminated with your own hands. However, if you are not confident in your own abilities or are afraid that it is impossible to eliminate the malfunction on your own, it is better to consult a specialist.

Fuel supply problems

If the engine does not start to work when starting to start, there may be problems with the engine itself or the launch system itself.

To eliminate malfunctions with the supply of fuel, you need to do the following:

• Check the spark plugs: if they are dry, it means that the engine does not enter the engine cylinders. Such a malfunction can occur when the blockages are formed in the gas tank cover, garbage entering the fuel supply system, with a closed supply tap or banal absence of gasoline.
• Seal the fuel tank and repeat the attempt to start the engine.
• Check the fuel valve: if it is closed, you need to change its position to open.
• Clean the drainage opening of the fuel tank.
• Drain the gasoline from the tank, the fuel valve was removed and rinse it with clean gasoline.
• Remove the connecting hose near the carburetor and blow it up (along with the jet).

If all these manipulations did not help, and fuel enters the carburetor, but does not fall into the cylinder, then the malfunction is in the carburetor and this detail needs to be carefully examined.

Repair of the carburetor

A common cause of malfunction of the carburetor is the presence of blockages. In this case, it is enough to disassemble the part, remove the source of pollution and collect again. This will help you with an instruction that is necessarily provided by the manufacturer (Figure 4).

Carburetor scheme

The main goal of all manipulations with a carburetor is to adjust the immersion of the float, which is attached to the piston system bracket. It often happens that the bracket was deformed, the float is plunged incorrectly and the carburetor operates incorrectly. The adjustment of the bracket is carried out with a regular screwdriver, both with open and with a closed needle valve.

After correction of the carburetor, it is also recommended to check the serviceability of the valves. It is necessary to check the fit of each of them and, if necessary, restore the optimal gap.

REDUTOR Repair

It often happens that during the operation of a walk.behind tractor, extraneous noises appear in its gearbox. As a rule, this is due to the insufficient amount of oil in it, and to eliminate the malfunction, it is enough just to add the liquid to the gearbox (Figure 5).

However, if the oils are enough in the gearbox, and the noise does not disappear, perhaps the brand and purity of oil are not suitable for your model. In this case, the oil must be completely drained, the system is washed and re.pour new, more suitable oil.

Reducer scheme

In addition, extraneous noises can be associated with insufficiently fixing transmission elements. They must be examined and, if necessary, tighten it denser. It should also be borne in mind that the elements of the gearbox must be examined and replaced in a timely manner when detecting the first signs of wear. So you can avoid more serious repairs in the future.

Engine malfunctions

Malfunctions in engine operation can occur both when starting and during operation. In this case, it is necessary to check the spark plugs. If they are dry, there is a problem with the supply of fuel, and if wet, the malfunction is in the engine itself.

One of the most common problems when starting is the failure of the ignition system. To eliminate such a malfunction, first of all, you need to inspect the electrodes of the candles, and remove the fence with the emery that could form on them. After that, the candles are washed with gasoline and dried. The launch problems can also be associated with the wrong distance between the electrodes. In this case, they just need to be carefully bent to the distance indicated by the manufacturer.

In addition, ignition problems can be associated with damage to electrical wiring or candle insulators. These elements are subject to replacement. Also, the absence of engine starts may be associated with stator defects. Unfortunately, it is impossible to fix this detail on its own and it will just have to be replaced.

often the engine shows signs of a malfunction directly during operation. This is due to the fact that a small agricultural equipment is subjected to high loads and requires regular inspection and prevention.

Note: if the one.axine tractor began to move jerks or publish extraneous noises, you must turn it off, let the engine cool down and only then proceed to the inspection.

The common problems in the engine are considered:

• An independent set of revolutions by the engine indicates that the levers of the regulator and traction are weakened and they need to be adjusted again.
• When you press the gas lever, the engine does not gain momentum, but rather loses its power. This indicates the overheating of the motor, so the equipment needs to be turned off and wait until it cools down.
• Blood interruptions in the engine can be associated with a block of air filter or muffler. The equipment needs to be turned off, cooled and examined to clean and eliminate blockages.

In addition, malfunctions in the operation of the motor may be associated with malfunctions in the carburetor or insufficient oil in it. In this case, the part needs to be disassembled, inspected and filled with new oil.

Reducer malfunctions

There are many reasons that can lead to a breakdown of this important node, which will operate the motor block of various manufacturers impossible. Among the main malfunctions characteristic of various models, it is advisable to attribute:

• oil flow due to a high degree of wear of the cuff;
• unsuitable lubrication parameters;
• the appearance of subtexts on the output shaft;
• rupture of the star;
