How to change rings on a walk.Behind tractor

Motoblocks. Generally reliable and stable devices. But with active operation, they still periodically break. Problems can touch even carefully thought out engines.

To understand breakdowns and eliminate them, it is important to understand how everything works in a normal situation. Let us dwell on greater simplicity only on models with ICE. Two.Stroke motor blocks used to meet, but now they are increasingly replaced by four.Stroke analogues. Diesel devices are also gaining popularity. As for the transmission, it can be performed in three different versions.

The traditional approach involves the use of gear transmission. Despite the decent level of reliability, this device takes up a lot of space. The transfer of effort occurs using either a cone or cylinder. Light motoblocks are mainly equipped with a gear-cherve transmission. The typical principle of operation of the motoblock regulator contains:

The control unit acts on the basis of pneumatic or mechanical communication. “Pneumatics” means the presence of a peculiar wing responding to the speed of the air flow. Centrifugal options involve the placement of a special distribution shaft inside the crankcase. It is complemented by small weights and an easily moving rod. The thrust is made of wire, and the sensitivity of the spring determines how accurately the speed values ​​will be maintained.

The role of the gas distribution mechanism is to supply a mixture of fuel and air into the cylinder. But the same device also ensures the removal of waste gases. To influence the degree of compression, decompressor is used. Gasoline motors are necessarily equipped with carburetors responsible for the preparation of the fuel-air mixture. Regardless of the type of fuel, the starting device plays an important role.

Malfunction of engine systems when starting

In the event that when checking the candles, they turned out to be wet, t.E. The fuel comes normally, but the motor does not start, the problem may be as follows:

  • Failure of ignition system:
  • On the electrodes of the spark plugs there is a characteristic incapacitance (it is necessary to clean the candles with the help of emery, after which they should be washed with gasoline and dried);
  • The gap between the electrodes does not correspond to the specified manufacturer in the engine operating manual (the clearance is regulated by bending the side electrode to the desired size);
  • I ignition or high.Voltage wiring mounts are damaged (faulty candles and wiring are subject to replacement);
  • The stop button is closed to the mass (for the normal start of the engine, the closure must be eliminated);
  • Contacts in candles are violated (contacts should be put in order);
  • The gap between the magnetic shoe and the starter does not correspond to the normative value (the clearance is required);
  • Defects were detected on the stature of the ignition system (the stator is subject to replacement).
  • Air sunset through the seals of the carburetor, spark plugs, heads of candles and cylinders, as well as carburetor joints and engine cylinders.

If depressurization of the compounds is detected, it is necessary to carry out tightening fasteners, tighten the candles and check the integrity of the gaskets between the heads of the candles and the cylinders.

To eliminate this problem, it is necessary to ensure the free course of the damper, checking the quality of the drive work. If you find seizures, they need to be eliminated.

Violation of compression and malfunction in the carburetor

It happens that the launch is carried out, but its process is significantly difficult. At the same time, the engine of the walk.Behind tractor operates extremely unstable and cannot develop sufficient power for normal operation.

The reason for this may be the loss of compression, which can be detected by:

In order to restore compression, you need:

  • Check the technical condition of the gas distribution mechanism of the engine, clean the parts contaminated by the pile, and in the presence of defects, replace them.
  • Check the condition of the piston rings and replace faulty components.

If in the process of operating the engine a black smoke comes out of the muffler, and an excess of oil is revealed on the electrodes of the candles or they themselves are covered with soot, this means that:

  • An oversaturated fuel mixture is supplied to the carburetor;
  • The sealing of the fuel valve of the carburetor is impaired;
  • The oil.Scrubbing ring of the piston was worn out;
  • Air filter clogged.
  • Adjust the carburetor;
  • Replace the leaky valve;
  • Replace worn piston rings;
  • Clean or replace the failed air filter.

In the event that when the engine is operating, light smoke comes out of the muffler, and the electrodes of the candles are dry and covered with white coating, this means that a lunch fuel mixture gets into the carburetor. This problem is eliminated by adjusting the operation of the carburetor.

The cause of the malfunction

The result of overheating is always one. Piston rings lie. That is, they burn the walls of the grooves. Lose their elasticity. Cease to fit tightly to the walls of the cylinders. The compression in the cylinders falls to the lowest level at which ignition of fuel from the spark may occur.

Compression disappears sharply. That is, the engine started and worked. At one point, they begin to start it, but nothing happens. Spark in place. Fuel comes. But the engine cannot be started. Forced fuel supply to the combustion chamber through the candle hole also does not lead to any results. You can certainly measure compression. But he is not always at hand. Make sure that the cause of the breakdown is low compression by artisanal.

To do this, you can add a little motor oil to the engine to get the engine to get the oil to the walls of the sleeve. Twist the candle and try to start the engine. He will begin to grasp and may start. But then he will stop starting again. This happens because the oil added to the combustion chamber will fill the worn places of the piston group. And for a short time will raise compression in the engine. It will be enough for the fuel to ignite the fuel. The engine will begin to grasp.

That is, an increase in compression leads to the fact that the engine begins to start. So the cause of the breakdown in the details of the piston group. As they say, the autopsy will show.

Other common problems when starting the engine

What to do if the motor.Block motor works with interruptions and does not develop the desired power? There may be several reasons for this behavior:

The air does not enter the carburetor, which means that the fuel burns poorly. The filter will have to be cleaned or changed.

The remains of fuel, as well as its combustion products, form a thick plaque on the internal walls of the muffler, which must be eliminated.

In this case, the node will have to be removed, disassemble and how to clean all its components. After that, the carburetor needs to be assembled and correctly adjusted.

The temperature and high loads do their job and even the most durable metal wears out and deforms over time. Such details should be immediately replaced, otherwise you can pay for this with non.Incomplete breakdowns in the engine itself.

The presence of a crankshaft when starting the engine is indicated about the presence of this problem. To replace the hull of the coupling and the ratchet, you will have to completely disassemble the starting unit.

If the launch cord does not return to its original position, the starter must be adjusted. For this, the screws are weakened, and the position of the node is set by hand so as to ensure a normal cord return.

A fairly common reason for the absence of a return launch cord is the failure of the starter spring. It will have to be replaced.

Significantly increases the service life of any equipment competent maintenance of its main components and components. The efficiency of replacing worn spare parts is also of considerable importance. Therefore, if the slightest failures and malfunctions arise, they should be eliminated immediately. As a result, this will prevent much more serious and expensive problems.

Do.It.Yourself repair

Repair of the CSW Motoboblock may be needed for various reasons. You suddenly had a strange smoke from the exhaust pipe, or the engine stopped gaining the right power, or uncharacteristic sounds appeared in the aggregate itself. All this is an occasion to turn off the car immediately, let it cool and start inspection, and further repair.

It often happens that incomprehensible sounds are associated with insufficiently twisted screws, so some detail simply vibrates from work. If you have everything tightly twisted and there are no cracks, you need to look for the reason in something else.

If you decide to repair with your own hands, then you should have a set of special tools, some skills and knowledge. Otherwise, the instructions and the desire to bring your equipment to the working condition will help you again.

How does it work?

To understand and eliminate the malfunctions, it is important to understand how everything works in normal conditions. In order not to complicate the situation, we will dwell on models with an internal combustion engine. In the past there were two.Stroke soil.Spaces, but they are increasingly replaced by four.Stroke analogues. Models with a diesel engine are also becoming more and more popular. As for the gearbox, it can be delivered in three different versions.

The traditional approach uses a re.Drive system. Despite decent reliability, this device takes up a lot of space. Power transmission is carried out using a cone or cylinder. Light mechanical screenings are usually equipped with worm gear with teeth. The typical principle of operation of the motoblock regulator is as follows:

The control unit works with a pneumatic or mechanical connection. “Pneumatic” means that it has the type of wing responding to the speed of the air flow. Centrifugal versions have a special distribution shaft inside the crankcase. This is complemented by small weights and easily moved rod. The hinged mechanism is made of wire, and the sensitivity of the spring determines how accurately the speed will be maintained.

The operation of the timing mechanism is to supply the fuel-air mixture in the cylinder. But the same device provides exhaust gases removal. To influence the degree of compression, decompressor is used. Gasoline engines are equipped with a carburetor, which is responsible for the preparation of the fuel-air mixture. Regardless of the type of fuel, the start system plays an important role.

If everything is done correctly, then The engine will respond normally to gas opening, without crashing. In addition, the speed will remain constant regardless of the degree of heating.

Repair of the carburetor of the MOTOBLOK “MROT”

Motoboblock carburetor was produced in Soviet times. Despite the fact that Soviet industry was famous for a high level of performance and reliability, this carburetor had a number of shortcomings. To understand them, first you need to make a complete analysis of its components:

  • Remove the lid, unscrewing the screw on it. Below we find a gasket made of gas.Resistant material, as well as a spring that needs to be pulled out.
  • Remove the damper located there under the hood.
  • There is a float chamber on the rear panel, which also needs to be unscrewed. Remove the gasket.
  • Then remove the float by removing the pin from the corresponding hole. There is a special needle under the float, which also needs to be removed. On it we find a small eraser that in no case can not be lost, so we carefully carry out all the manipulations.
  • Unscrew the fitting under which the gas filter is located.
  • Then remove the nozzle. After that, we need to pull out absolutely all the “insides” located in the carburetor case.

Such disassembly is required., because we get access to internal content, which is considered the most problematic.

The most common disadvantage of such carburetors is the adjusting screw, which is responsible for the quality of the mixture.

In other words, we return this screw, but the mixture does not change, it remains constant.

To change this, you need to make some repair of a carburetor located inside a mole. The main reason for problems with adjusting the mixture is one circumstance. The fact is that there is a special channel inside the carburetor, which extends to the tube located in the center of the carburetor.

T-70C is a multifunctional center for a wide range of activities. Follow the link to get acquainted with the advantages and features of the T-70 tractor.

Bulldozer. Caterpillar or wheel excavator related to the class of special equipment. Monster bulldozers. The world’s largest car inventory.

In the market of our country, products of a large number of world manufacturers of snowman are presented. It’s all about the legendary German snowman Hutter.

In this pipe, the theoretically should be a through hole connecting the same channel. The problem is that on some installations this pipe is located inclined, which leads to overlap of the channel and holes on the pipe.

There are such times This hole is completely absent in the pipe, or it has insufficient diameter. To complete the repair, we need to take a few steps:

  • Remove both adjusting screws. Please note that the screws have different cones. This screw has a greater quality of the mixture cone.
  • To get the pipe inside, we need to heat the part that outside a little. You can use a small fire on a gas stove or heat it with a regular light-koy.
  • Gray, while he cannot keep the matter. Then we insert the hairpin into the hole where the bolt of the cover is located.
  • With the help of a hammer, carefully hit the inserted hairpin until the pipe jumps out.
  • As practice shows, The hole is drilled only on one side of the pipe, those. It’s not to the end. We need to make a symmetrical hole on the other side of this tube or change what is.
  • If there is a second hole, but it is less in diameter than the first, then we need to sharpen it a little. To do this, use a regular circular file, drill the edges of the hole.
  • Then install the tube in your former place. This should be done so that the through hole on it and the hole on the channel exactly match.
  • Before inserting the pipe, You need to warm up the carburetor housing, So she can easily get into her place.
  • Insert the phone into place and with the same finger with which we inserted the phone, insert it into place. Cut off slightly so that the pipe does not go far inside. You must see the back, just above the aisle, which should coincide with the channel.
  • Make sure the hole is in the center.
  • Take a tight wire and insert it into the opening of the duct. If everything is done correctly, the wire must freely pass through the through hole in the pipe and go out of it through the carburetor channel.
  • If the wire is restrained, you need to tap a little on the pin, slightly moving the pipe.
  • Then you need Collect the carburetor in the reverse order.

That’s the whole process of making the necessary changes to the design of the carburetor. Thanks to them, the adjusting screw fully fulfills its obligations to change quality, which, in fact, is required.

Conclusion

Using Molo.Block mole Widely used in many regions of our country. This is not a coincidence, because with the help of simple modifications you can get a very powerful block from it compared to more expensive models.

But even without this, even the factory version of the engine is able to cope with most of the tasks set before it.

However, for this it is necessary to periodically set up the main work units of the device.

1962 Simplicity Walk Behind Tractor Model W in Action

This frequency is indicated in the operating instructions attached to the engine. It contains all the details on how to adjust it, and also when to do it.

Installation of piston rings on a walk.Behind tractor

Sooner or later, your motor will be worn out and will require either a change of piston rings or a piston in general.

It seems to change the piston rings is an ordinary task available to everyone who is more or less familiar with the device and the principle of operation of a primitive four-stroke motor. But, unfortunately, people are afraid to spend 15 minutes of their incredibly precious time reading literature and stuff everything into the motor according to the principle (as well as stood. Will probably work). Well, the flag is in your hands and the speedy appeal to the service.

So, take the piston and see 3 grooves for the installation of piston rings. There are no restrictive stoppers on 4-stroke engines, as on 2-stroke engines, for example.

There are two types of piston rings on 4-stroke engines. The first two, which are installed in the top two grooves, are compression. Based on the name, it is clear that they are responsible for the presence of compression in your motor and properly to keep the gases that form at the time of the outbreak due to combustion of fuel in the combustion chamber.

The following three rings are oil.Scrubbing. Here, too, their purpose is also clear. They are responsible for relieving oil, which covers the cylinder walls at the moment when the piston returns down. If these rings are passed, then the oil will remain on the walls of the cylinder, and this is fraught with the fact that the engine will begin to burn the oil, and, of course, smoke will appear.

Utility trailer mounting to walk-behind tractor

How to install primary? Yes, in principle, as they stood from the factory, in the same order, but in order to avoid mistakes, we show again.

Initially, we put the main oil scrap ring: that which has a wave.Like structure. There is nowhere easier to install it, since it is the most elastic of all.

Then put the upper and lower thin oil scrap rings. They are a little harder, but there should be no problems with their installation either.

replace, rings, tractor

Now we put piston compression rings: those that are thicker and “hard”. Initially, install the lower, then the upper. Put them a little more difficult, since they are less elastic and more solid. You are unlikely to break them, but with completely crooked hands to bend them easier.

See also  What kind of oil to fill into the engine of a single-axle tractor Salut?

The fact is that the rings still need to be properly placed on the piston so that the locks of the rings (the location of the drink) do not fall on top of each other. Simply put, it is necessary that the lower ring is not located right above the cut of the upper ring.

The castle of the lower ring is placed in the middle above the valve cavity, for example, inlet (you can also graduate, there is no difference here).

The locking of the upper ring is placed strictly on the opposite side of the lower ring. Accordingly, if the lock of the lower ring above the cavity under the inlet valve, then the upper castle above the cavity under the outlet valve.

Now go to the oilfly rings. These rings must be placed in the same way so that not a single castle coincides. Therefore, the upper ring is located above the hole under the piston finger, on the right side.

The second (that which is lower) is placed on the opposite side, also approximately in the middle of the hole under the piston finger.

The last wave.Shaped oil.Welded ring is placed in any of the four resulting sections between the opening under the finger and the cavity under the valve.

And now to your question: what kind of nonsense is the author rubs us here? And why so painstakingly set the position of all 5 rings?

Explain. We did all this so that it did not happen that when one castle was located above the other, gases do not pass through these locks (in the case of piston rings) and did not remain on the walls of oil (in the case of oil.Cut rings).

If we take into account the piston rings, then this is the loss of compression and the passage of hot working gases to oil.Beet rings, which are not designed for such sudden high operating temperatures. As a result, the rings after a certain time can burn out

If we turn to the oilfield rings and the coincidence of the locks on them, then we will not be completely removed by the oil: it will reach the piston rings, which will lead to the hair strokes of the rings, and as the result they will varify, and then burn out.

As a result, you will receive burned rings and wear of the piston.

Bottom line: set the locks of the rings before installation. This is the case of 2 minutes, and the life of the motor this operation can extend for tens of hours.

Fuel passage problems

The fact that the fuel enters the motor cylinder may indicate the condition of the candle. It must be checked by twisting the cylinder from the lid, connecting the wire in advance. If the candle is dry, then this means that the fuel does not get into the cylinder. If you managed to find out that it goes to the carburetor, then the main reason for the engine failure of the launch may be the clogging of the device of the device filter.

Sometimes the clogging of the nozzles leads to serious problems. Subject to all conditions, the instructions for repairing the walk.Behind tractor provides for the possibility of removing the carburetor, disassembling and cleansing the part. These manipulations can be performed without visiting the master.

Checking the condition of the candle

The recommendation for the repair of the unit, which you must be studied before the work, will help you realize how to carry out the inspection of the condition of the candle. If it is wet, then gasoline goes into the cylinder. Refusal to launch may be due to an excess of a special mixture.

If the surface of the candle is strongly covered with gasoline, you need to dry the cylinders, pump the engine with a starter, leaving the candle in a well.Twisted state.

Before this manipulation, the master should close the fuel supply. The candle may be clogged, At the same time, it is cleaned with a small skin and gasoline. The main thing is to analyze what value the gap between the electrodes will have. If necessary, then it is worth adjusting, following the rules submitted by the manufacturer in the instructions. The size of the clearance should be 0.8 mm.

Replacement and adjustment

Quite often, unfortunately, there is a need to completely change the motor on the walk.Behind tractor. When choosing a device for replacement, it is recommended to give preference to products of well.Known companies. Traditional prejudices about the products of Chinese factories have long been irrelevant. To avoid overpayment of funds, it is necessary to carefully analyze how productive the power plant should be. Buying too powerful the unit is simply irrational.

If even there is no talk of a complete replacement, it is important to know how to adjust the agricultural engineering engine. It is advisable to start disassembly only after washing the motor and removing oil from it. Lubrication is poured only with the engine heated after short operation. Next, the time comes to remove the fuel tank. They are sequentially removed:

Gravely Walk Behind Tractor. Set Timing Without Removing the Head

Then remove the crankshaft pulley. Following the pulley, it is required to remove the fan, reflectors, insulating the casing of flywheels. Unscrew the lid, removing the rings and hulls of the couplings. When the puck is removed, you can extinguish the flywheel using a wooden bar.

Now, having dealt with the flywheel, remove the cylinder cover, distributing the shaft and pusher. As soon as access to the connecting rod is obtained, the oil sprayer and countrogike are removed. Having repaired and changed damaged parts, the engine is assembled in the reverse order. You should familiarize yourself with the scheme in advance, then there will be no errors.

Change of damaged valves for a gasoline walk.Behind tract occurs after removal:

Often there is a need to replace the rings. But this should be done only in the process of more serious repair. The isolated change of rings in itself is irrational both in economic and technical terms. In addition, the high.Quality ring group usually has the same service life as the cylinder. Change them at the same time.

Installation on an elastic Band is advisable if a Chinese motor is placed on domestic motoblocks. Rubber pillows are often used as a site. Parts of the front shock absorber from the car of the classic scheme are suitable as them. Along with the need to rearrange the individual parts of the engine engine, many people have a need to put an electric starter yourself. This starter will have to correctly connect to the battery.

The crown is attached only to the removed flywheels. Pre.Remove all the interfering parts of the motor. To remove the flywheel in many cases, you can not do without a special key. A generator and its magnets are placed in the fly node. When the terminals and contacts of the batteries are combined, a trial launch of a walk.Behind tractor should be carried out.

The advantages of Chinese engines

Chinese engines for motor blocks have gained immense popularity due to their advantages. Depending on their purpose, motors are equipped with additional equipment (gearboxes, starters, etc.). Only the latest equipment is used in the production of engines. Having bought such a engine, you can immediately use it, without additional preparation. They are completely suitable for all types of motoblocks, even for home.

What is a friction ring on a snowman and how to replace it with your own hands

The design of the snowpock machines in itself is not particularly complicated. Therefore, here the working nodes do not fail so often. Several elements can be distinguished that are subject to the greatest wear. These are drive belts, cuts and friction rings.

If we talk about the friction ring, then we are talking about a simple detail, but when it breaks it, the snowman cannot move. In theory, a new friction ring can be made with your own hands, but objectively easier, more reliable and safer to buy a new part. The task of the owner of the snowpipe is to monitor the condition of the friction ring, as well as other consumables, and timely change them when signs of wear.

The purpose of the friction ring

Before changing the friction ring, it will not be superfluous to figure out what kind of element it is, why it is needed and what functions performs.

Wheel snowpock machines are equipped with friction rings. This is an element that is part of the transmission. The task of the ring is to ensure the rotation of the snow.Offer wheels at the speed that was chosen by switching the transmission lever by the operator.

The clutch rings themselves are most often made of aluminum alloy, although there are also made of steel received by stamping. In shape, the element looks like a disk and a rubber seal is put on it.

From the name it becomes clear that the friction ring is subject to friction effects. But in normal mode, wear occurs quite slowly. Such an element does not have to be changed every 5-10 hours of work.

Causes of premature wear

Some of the owners of snowbreakers are sometimes surprised why the device does not want to go. And the reason is in the worn ring of the friction.

It looks strange that such a detail has so quickly worn out. But the reason is usually the user itself. That is, premature wear is directly related to the errors that the user of the snowman admits during operation.

The most common reasons include the following:

  • Gear shift without stopping technology. Working with a snowman, very often the operator switches the speed on the box, but does not stop the cleaner. And here the load affects the first thing on the rubber seal. For some time this elastic lining can still protect the metal component. But it will not last long. Rubber wears out quite actively. When the rubber gasket is destroyed, the entire load falls on metal friction. Gradually, this leads to destruction, and the technique simply stops, stops going along the site.
  • Careless management. Another possible reason is incorrect management of the snowman. The operator tries to quickly cope with large snowdrifts, actively goes into the rise, without sparing equipment, passes through complex and uneven areas. The pins of the snowman can at the same time be very slip. As a result, due to this movement of the wheels, they mechanically affect friction, creating a large pressure. This leads to Rapid abrasion. As a result, quite deep grooves appear on a metal surface, the gap changes, and the friction clutch ceases to perform 100% functions assigned to the ring.
  • Dampness. A problem from which there is no. Friction is afraid and really does not like increased damp. Although you have to work actually with water. Dampness leads to active processes of corrosion formation. If aluminum can still resist it, then steel seriously suffers. At the same time, aluminum can crumble, turning the friction ring into almost powder. And steel clutch are covered with rust. The only resistant to damp element is the rubber seal. But there will be no sense from him if the metal part of the friction ring has worn out.

Understand that the friction ring was subject to corrosion is quite simple. During operation, a strong and distinct creak of the node is manifested. Over, this occurs precisely at the time of gear shift.

It is impossible to protect the snowball player in winter from snow. But when the equipment is sent for long.Term storage before the next frosts, it is very important to remove the remaining talus and water from the cleaner as much as possible, as well as choose a place with a minimum humidity level. Many owners of snow.Offers additionally use conservation products that protect the metal from corrosion and the appearance of rust.

How to replace the friction ring yourself

Some details of garden equipment, including snowbrushes, can be restored. But not in the case of friction rings.

If a metal ring with a rubber seal is worn out, then the only option would be to replace it.

It is not so difficult to deal with the replacement of friction rings on snowbrushes. This procedure can be carried out with your own hands in garage conditions. And since the friction material is a consumable, then, depending on compliance or non.Compliance with operation rules, the interval between replacements can be different. Someone changes the part very often, others cost one replacement for several seasons. The factory quality of the freezes, as well as the level of execution of the snowman himself, plays an important role. Practice shows that on budgetary models of snow removal equipment, consumables wear out faster, which involves a more common replacement.

The principle of device and design in snowbrows is largely identical. And therefore, you can replace frictions according to universal instructions.

Correct installation of piston rings

Sooner or later, your motor will be worn out and will require either a change of piston rings or a piston in general.

It seems to change the piston rings is an ordinary task available to everyone who is more or less familiar with the device and the principle of operation of a primitive four-stroke motor. But, unfortunately, people are afraid to spend 15 minutes of their incredibly precious time reading literature and stuff everything into the motor according to the principle (as well as stood. Will probably work). Well, the flag is in your hands and the speedy appeal to the service.

Well, for those who do not care how their motor will work after bulkhead, you should read this article.

So, take the piston and see 3 grooves for the installation of piston rings. There are no restrictive stoppers on 4-stroke engines, as on 2-stroke engines, for example.

There are two types of piston rings on 4-stroke engines. The first two, which are installed in the top two grooves, are compression. Based on the name, it is clear that they are responsible for the presence of compression in your motor and properly to keep the gases that form at the time of the outbreak due to combustion of fuel in the combustion chamber.

The following three rings are oil.Scrubbing. Here, too, their purpose is also clear. They are responsible for relieving oil, which covers the cylinder walls at the moment when the piston returns down. If these rings are passed, then the oil will remain on the walls of the cylinder, and this is fraught with the fact that the engine will begin to burn the oil, and, of course, smoke will appear.

How to install primary? Yes, in principle, as they stood from the factory, in the same order, but in order to avoid mistakes, we show again.

Initially, we put the main oil scrap ring: that which has a wave.Like structure. There is nowhere easier to install it, since it is the most elastic of all.

Then put the upper and lower thin oil scrap rings. They are a little harder, but there should be no problems with their installation either.

Now we put piston compression rings: those that are thicker and “hard”. Initially, install the lower, then the upper. Put them a little more difficult, since they are less elastic and more solid. You are unlikely to break them, but with completely crooked hands to bend them easier.

The fact is that the rings still need to be properly placed on the piston so that the locks of the rings (the location of the drink) do not fall on top of each other. Simply put, it is necessary that the lower ring is not located right above the cut of the upper ring.

The castle of the lower ring is placed in the middle above the valve cavity, for example, inlet (you can also graduate, there is no difference here).

The locking of the upper ring is placed strictly on the opposite side of the lower ring. Accordingly, if the lock of the lower ring above the cavity under the inlet valve, then the upper castle above the cavity under the outlet valve.

Now go to the oilfly rings. These rings must be placed in the same way so that not a single castle coincides. Therefore, the upper ring is located above the hole under the piston finger, on the right side.

The second (that which is lower) is placed on the opposite side, also approximately in the middle of the hole under the piston finger.

The last wave.Shaped oil.Welded ring is placed in any of the four resulting sections between the opening under the finger and the cavity under the valve.

And now to your question: what kind of nonsense is the author rubs us here? And why so painstakingly set the position of all 5 rings?

Explain. We did all this so that it did not happen that when one castle was located above the other, gases do not pass through these locks (in the case of piston rings) and did not remain on the walls of oil (in the case of oil.Cut rings).

If we take into account the piston rings, then this is the loss of compression and the passage of hot working gases to oil.Beet rings, which are not designed for such sudden high operating temperatures. As a result, the rings after a certain time can burn out.

If we turn to the oilfield rings and the coincidence of the locks on them, then we will not be completely removed by the oil: it will reach the piston rings, which will lead to the hair strokes of the rings, and as the result they will varify, and then burn out.

Earth cultivation

The purpose of the Lifan motor cultivators is a high.Quality cultivation of land for planting, caring for seedlings and harvesting. This type of technique is great for processing areas of medium and small area with any relief and various types of soil. The land plowing on this unit is available to a depth of 200 mm, which allows only a fertile soil layer to dig out, leaving more deep clay layers untouched.

Thanks to the large selection of attaching equipment using the Lifan motornote, you can carry out any kind of personal work depending on the season and needs of the consumer. Changing the components of the motor.Cultivator can be used all year round, starting with plowing and landing, and ending with snow cleaning in the winter.

The standard equipment of the walk.Behind tract includes:

  • Cutters.
  • D350 mm wheels for a walk.Behind tractor.
  • Plow.
  • Hayfield.
  • Potato.Cap.
  • Pump equipment.
  • Snow removal equipment and others.

The power of the Lifan engine in the latest models allows you to easily treat virgin lands with complex mixed soil. However, when working with a motor.Cultivator, do not forget about the need to maintain technology maintenance.
