The diesel diesel engine of the walk -behind. Engine problems

Do not start a diesel engine of a walkway cause

Often, owners of agricultural machinery are faced with various malfunctions. For example, the same.based tractor does not start and shoots. To eliminate the breakdown, first of all, it is necessary to determine its cause.

Then they independently engage in the direct repair of equipment or contact the service center. In this article we will talk about why the same.based tractor is not starting and how to fix it.

Possible reasons

The same.based tractor starts and stalls? Why is this happening? The reasons why motor equipment does not start when starting, there may be several. You can classify them:

• damage to the carburetor (in units with a gasoline engine);
• a defect in ignition and incandescent devices;
• Low level of basic lubrication.

When unusual changes occur in the unit, and its work is done unstable, first of all, the carburetor is checked. In this significant node, the fuel-air mixture (TVS) and the dosage of it for supply to the cylinders of the internal combustion motor (ICE) are performed. And if the jackets are clogged, the obstruction of the fuel system appears, due to which the carburetor loses the ability to guarantee the start of the engine. In order to eliminate the defect, repairs of the fuel supply are carried out, which implies a partial analysis of the carburetor, flushing the pump, purging the nozzle through the fitting fitting.

If the unoic tractor Neva does not start, the reasons can also be different. Sometimes the problem is hidden in a malfunction of the spark plugs that play an important role in starting a carburetor ICE, or a candle of incandescent, which ensure the launch of a diesel engine. If the fuse devices are made wet, which happens due to throwing their TVS, the spark begins to disappear in them. In the absence of sparking, the ignition of the fuel-air mixture is not performed, and, therefore, the motor does not start.

You can solve this problem in various ways:

• carry out insignificant repairs and change non.working candles to new ones;
• “Burn” flooded candles and use a flame to clean them from traces of fuel.

The technique is not started and due to the fact that there is a defect in the glow of incandescent. In the diesel engine, the fuel ignition is performed from contact with hot air, which is warming up in the cylinder when the piston is compressed. This happens without complications if the unit has already been heated, and the heated walls of the cylinder hold the operating temperature in it. However, in cool weather, the heating of the motor is performed using incandescent devices, and if they broke, it will not work to start a single.axle tractor.

If, when examining the carburetor engine or diesel, there were no defective candles, but the difficulties were preserved, and they are also accompanied by cotton into the silencer, it is necessary to control the functionality of absolutely all the devices responsible for the ignorance of the fuel. The defect in them may also be a prerequisite for the fact that the one.axine tractor will not start. It is more correct to diagnose in the service center, where experts will find the cause of the damage and qualifiedly will be restored.

Motics is not started and with a lack of lubricant in the engine. Certain modifications are equipped with special control sensors, which, if a lubricant lacks, prevent the motor. Particular attention must be paid to those options for machines that do not have such meters. Sooner or later, the degree of lubricant mixture will reach the ultimate value, and if it is not compensated to the norm, this will soon lead to wear of elements and, as a result, to the overhaul of the motor.

The main malfunctions of the motoblocks

Diesel and gasoline engines have different motorized resources. For the first, a normal figure is 4000 m/h, but the latter can provide only 1,500 m/h. Despite this, diesel models of motoblocks are not in high demand. After all, both when buying and during operation, they are much more expensive. Therefore, most likely, you work with a walk.behind tractor equipped with a gasoline (carburetor) engine.

All breakdowns that can occur during the operation of agricultural minute can be divided into two categories:

• Engine malfunctions:

• starting problems;
• Dot in work.

• Malfunctions of other nodes and mechanisms:

• improper clutch work;
• breakage in the gearbox;
• problems with the chassis;
• control and automation malfunctions;
• malfunctions of the motor block systems (cooling, lubrication, etc.).

In many ways, the success of the repair of a suddenly failed machine depends on the correctness of the diagnosis. As for maintenance, it is carried out precisely in order to identify small malfunctions, which will subsequently lead to serious.

If you do not have the necessary knowledge, room, tool and materials necessary for the maintenance and repair of the motor, trust the specialist!

Fuel supply problems

If attempts to start a single tractor were unsuccessful, this means the presence of malfunctions in the engine or launching system. In order to determine the source of the breakdown, first of all, it is necessary to check the spark plugs.

If the candles are dry, it means that the fuel mixture does not enter the engine cylinders. There may be several reasons for this:

• There is no fuel in the tank;
• The fuel supply crane is closed;
• The hole in the riveted tanning rod was clogged;
• Narround objects were included in the fuel supply system.

To eliminate problems with the supply of fuel, you need:

• Refun the tank of the walk.behind tractor.
• Open the fuel valve.
• Clean the drainage hole located in the tanning rope’s cork.
• Remove the fuel valve, drain gasoline from the tank and rinse it with clean gasoline. After that, the connecting hose located on the part of the carburetor should be removed, and blow it together with the jackets of the carburetor without disassembling the latter using the fuel pump.

If the fuel enters the carburetor, but does not reach the cylinder, the problem is in the carburetor itself. To eliminate it, this node must be removed, disassembled and cleaned. Well, after that. collect and install in place. Therefore, before performing all the necessary manipulations, the device and the principle of operation of the carburetor will not prevent the device in memory.

Why is the one.based tractor working with interruptions?

Among other typical malfunctions of the walk.behind tractor, a number of such breakdowns can also be distinguished:

• The aggregate motor hits the return. this indicates the use of poor.quality fuel for refueling the unit. In this case, you will have to not only replace the fuel, but also thoroughly rinse the fuel pump and fuel supply hoses;
• The same.based tractor works with jerks. the reason for this lies in the insufficient heating of the motor. Be sure to drown out the engine, wait for it to cool completely, and again start the motor, giving it at least 10 minutes for full heating;
• The motor block does not noticeably pull, the engine power has decreased. in this case, you need to check and, if necessary, clean the air and fuel filter. Another reason for this breakdown lies in the wear of the magnesium magneto. It is best to immediately replace the part without trying to restore it.

The owner of both gasoline and diesel motoblock is equally often faced with this kind of malfunction. In any case, you need to immediately stop working with the machine, and as soon as possible to eliminate its breakdown.

Why is the one.based tractor working with interruptions?

There are other malfunctions that should be considered:

• The engine of the walk.behind tractor hits the return. The reason is often the use of bad fuel. It will not be enough to replace the fuel. Flushing the pump and hoses to supply fuel;
• The technique works with jerks. The engine does not warm up completely. The motor needs to be drowned, wait for its absolute cooling. After re.start it and warm it up for at least ten minutes;
• The engine does not pull, because the power of the motor decreases. The filter system is checked and cleaned. The problem can provoke the wear of the ignition magneto. In this case, the details are replaced.

Owners of technology, both gasoline and diesel type, may face such problems. Regardless of the specifics of the breakdown, you need to urgently stop using the unit and begin to eliminate the problem.

Work specifics

The operation of the described device occurs due to the efforts of the engine, so that the unoic tractor sets in motion and transfers energy to the other elements installed on it. The main structural component of the walk.behind tractor is considered to be the soil.graze designed to eliminate weeds, plowing and equipping the earth with fertilizers. Often, the repair of the walk-behind tract occurs precisely in this part of it due to the fact that the highest load is on the soil in the process of operation.

complex variations of the walk.behind tract sometimes have a hanging equipment in their design, which significantly expands the functionality of the device.

In addition to soil.graders, the same.based tractor may have the following components: cultivator, plow, mowing, hip, etc.

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.

DIY engine engine repair, video

Auto mechanic, specializes in agricultural technology

Undoubtedly, every farmer, farmer, gardener, arg.industry should have a mechanical assistant. Sometimes the human resource is simply not enough to carry out a particular work. Such electrical mechanisms quickly and effectively cope with what the person needs a lot of time. Among this:

Before choosing this device, it is important to understand the differences between the walk.behind tractor and the cultivator, as these are different mechanisms.

Do not forget to disassemble various models of motoblock data

The cultivator is an unit for cultivating and processing the soil. The main characteristics of the cultivator are as follows:

• It is suitable only for the cultivation of soil;
• cannot perform other functions, such as cleaning, transportation;
• The power unit can be 2 types. gasoline and electric;
• The price of them is much less than motoblocks.

This mechanism has a more complex structure and, as a result, multifunctionality. The main features of this mechanism:

• a wide range of attachments, which can be used paired with it;
• Using the trailer as additional equipment, you turn your uno.based tractor into a good vehicle for cargo transportation;
• wide selection of both domestic and foreign models with powerful engines.

Thus, if for you the main goal is to cultivate the soil, feel free to choose a cultivator. If you want to use the unit to complete other tasks, the best solution would be a one.axle tractor.

In this video, you will learn how to choose a single tractor:

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:

• 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 candles and 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.

Motoboblock transmission malfunctions

The clutch malfunctions depend on its type. If the one.axine tractor has a belt, which performs the role of clutch, slipping can occur if there is oil pollution on a drive belt or pulley, the belt is not stretched or too worn out. Methods of correcting these problems are obvious. to clean the transmission elements from pollution, pull or replace the belt.

In a dry disk clutch, the cause of slipping may be the presence of oil pollution on the driven and leading discs. It should be removed by washing the disks with gasoline and dried.

Regardless of the type of adhesion (dry or oil) to slip, the wormwood of the friction layer of the disks, the weakening of the compressive spring, the absence of a clearance between the pressure element and the squeezing bearing. The method of correction is determined by the nature of the malfunction.

The clutch does not turn off completely. In this case, you should also start by checking the tension of the cable coming from the control handle to clutch.

Deformation of the friction discs, their sequeling on the slots, the mismatch of the required parameters of the oil characteristics filled into the clutch crankcase can also lead to incomplete shutters. The latter belongs to the couplings working in the oil bath. It is necessary to replace deformed discs, eliminate the reasons for their sequel on the slots, replace the oil.

Increased noise in the gearbox (gearbox). Noises in the gearbox can occur due to a lack of oil in it or the inconsistency of its quality by the necessary parameters-according to the brand and cleanliness. It is necessary to add oil to the motorblock gearbox or replace it.

Transmission nodes can make noise due to banal tightening fasteners. You need to view and tighten them.

Most often, noise arises due to the wear of gears and bearings. In this case, they are harbingers of more serious breakdowns. Timely repair of the motorblock gearbox, which consists in replacing worn parts, will help to avoid them.

Do not turn on, spontaneous shutdown or difficulty in switching speeds. These malfunctions can occur for a number of reasons:

• Due to the wear of the details participating in the switching of the speeds. Usually there is a wear (flashing) of the ends of the turned on the gears, which leads to incompletely turning on and self.turning off the speeds. In this case, it is necessary to disassemble the gearbox of the walk.behind traffic and the editing of the teeth with gear with grinding or, if the wear is too large, their replacement.
• Due to the abrasion of shafts, as well as the displacement of shafts in the axial direction due to wear of bearings and stop rings. You can adjust the axial position of the shafts by installing additional locking rings. Overly worn bearings and rings must be replaced.
• Due to improper adjustment of the clutch, which can lead to the difficulties of gear. The clutch is not squeezed out (off) until the end. The inexperience of the operator who releases the clutch lever when switching the gears can lead to the same. It is necessary to adjust the clutch and learn how to switch the programs correctly.

Gearbox. rather complicated knot. If the work and device of the walk.behind tractor represents a complete secret for the user, do not start repairing it yourself. It is better to entrust this work for those for whom the maintenance and repair of machines is a professional business.

Transmission nodes are warming up. Among the main causes of this malfunction are the wear of the bearings, the insufficient level of transmission oil in the crankcases, the inconsistency of its condition for the required parameters. Correction measures: replace the bearings, add or replace the oil.

Leakage from the gearbox (gearbox). This occurs with worn.out or incorrectly installed sewing nodes, not tightened lids or damaged gaskets under them, clogging the air valve (saopun) of the oil of the oil of the oil, filling the oil into the crankcase above the norm.

Motoboget instability when moving (screening). A different pressure in the right and left wheel, uneven wear of the tire tread, improper adjustment of the trailed devices, in particular, the plow leads to this nature of the motoblock movement.

Increased vibration of the walk.behind tractor. Increased vibration usually happens with improper adjustment or weakening of fastening of hinged devices (cutters, rotor braids, etc.). In case of vibrations, you should immediately stop the one.axle tractor and put the trailed devices in order. fix the mills or cutting segments of the rotor braid, replace them if they are worn out or broken.

The article lists only the most common malfunctions. The practice of operating motoblocks is replete with a much wider list of malfunctions. both atypical, which is sometimes very difficult to diagnose, so those whose nature and place are not in doubt.

If you can’t eliminate the motoblock malfunctions on your own, the only option remains. contact the service center for maintenance and repair of motor blocks.

Engine change on a walk.behind tractor, twice!

Continuing this WWW entry.Drive2.ru/c/518910115756114693/, relying on the majority opinion, it was decided to buy a new engine.For a long time darted at the choice of the quantity of l.With. Most exploit 6.5l.With. and for the personal plot of these Chinese horses enough. But one person advised me to buy 9l.With., t.to. 6.5l.with weak on the bottom. Well, I, after watching one video (this clearly convinced me in favor of 6.5l.c), where the guy without much effort cleans snow from 6.5-horsepower engine, well, I decided to take 6.5l.With.On the house and I bought a new Lifan 168f-2 6 motor.5l.With. New skif 20mm and transition fruiting.

In a couple of days I installed everything. The site is a good thing, the engine position on the frame of the walk.behind tractor is easily adjustable. I started to try to clean the snow. Small, Santimov 10, he takes, but where the engine is closer to 20cm, then he will die out. And to give full gas is scary, the engine is new, it was not worked out. I shook not a deep virgin to clean the same effect, rests and stalls.Told everything to a comrade, in fact, with whom I saw all this farm, though he has a 7l Neva.With. Subaru and the same prefix as mine. As he said. there are no miracles. Of course I was a little upset and decided to sell this

And buy more help.170f 7l.C and 170FT 8l.C I did not consider T.to. They are made on the basis of 168f-2, the difference is only in the pistons. And in 8l.With at all it is not clear where this horse came from, t.to. He is identical to 7l.With.I went for 9l.With. The price for it is almost 2 times higher than 6.5-horsepower. Well, what to do, I had to take. I wanted to take the Forz, 2t.₽ is cheaper than a lifan, but was not available. And bought a transitional site

, The skif came up, also 25mm.He began to put the motor, and he rests on the gearbox, and some kind of strange site, there are no holes for fastening to the frame. In general, it was possible to put on this site, but it would be necessary to move the engine ahead. outside the frame. Made his own, from a profile stub 25 × 40 × 2. At first I tried on plywood on pieces, as it will be better based on the length of the working belt. Then he drilled holes for the bolts, then on the bolts, the width between the longitudinal pieces of the pipe. I did as wide as possible so that the holes in the motor on one side are oval

t.to the holes on the engine of 11mm and grabbed them to the site, and fixed the site to the frame with bolts M8 T.to. It has 8mm holes in it. The bolts displacement vertically made about 10mm, but it was better to make 15mm.

Of the minuses of this adapter, that the native casing is not suitable, the engine is high.

I will think another bracket for the casing, otherwise open belts are very unsafe.The first day of operation showed the serving: the relics of this unit are more than enough. If at 6.5-horsepower calling into a snowdrift and he shuddered, then this rush is like a tank.,

If he rested where, then he begins to slip or if he did not have time to throw it away, then the screw wedges with snow and the belt begins to burn, smoke with a pillar, scraps fly. 6.5-horsepower for a long time stalled. But this option suits me more.

Py.SY. To exclamations, yes x.th is necessary, a specific snowman is better and t.D. I will answer so that this like a snowman sore me at the price of a cheap electric, the purchase of an engine for a single tractor in this subject I do not attribute T.to. I will use the motor block year.round. And the prefix takes less space than a full.fledged snowman.
