How to start a diesel single axle tractor without a starter

How to start a tractor with a single axle engine Lifan

So, you own a new power tiller to take care of your vegetable garden, orchard, and even the homestead. The first thing to start with. is to check the oil level. Even if you are sure that there is enough of it or you were assured in the store that it is poured in full, you still need to check. If the oil is not enough, you can simply ruin the engine. Also the car might not start if the oil was filled a long time ago and has gone bad. Some engine models, such as Subaru or Lon Chin, have a special sensor that just shows how much oil is in your machine.

After that you need to fill up the fuel. Your owner’s manual should tell you what kind of gasoline is right for your power tool. You can also ask the seller for this information. Another important point applies to two-stroke engines, where gasoline must be diluted with oil in a certain proportion.

Only then can you go straight to the inspection of your complete power tool. That is, you have to check all the joints, the steering and wheel mounts, the clutch and throttle cables, and so on.

Conditions for successfully starting a diesel engine

Single-cylinder, four-stroke diesel engine

To begin with, let’s refresh our memory on what happens inside a diesel engine when we try to start it:

Each of these items is called a tact, and all together. it’s one cycle of a four-stroke diesel engine. Let’s take a closer look at the stroke.

Cycle of the diesel engine

Air inlet

Air is needed to ignite and burn the fuel. It is drawn into the combustion chamber by the vacuum created by the cylinder piston group.

Hereinafter, the CPC is the cylinder-piston group, which includes the cylinder (or cylinder liner), piston and piston rings.

The piston moves down during the first stroke, creating vacuum in the cylinder. When it begins to do so, the intake valve must open. The air passes through the filter and enters the cylinder. The latter is necessary so that the fuel injected later would be immediately mixed with it, so that an air-fuel mixture suitable for ignition and combustion would be created.

The intake stroke is complete when the piston reaches the lower dead centre. At the same time, the intake valve has to close completely.

Compression and injection

After the first stroke of the stroke, the piston moves upward. Since both valves must be closed, the air previously stored has nowhere to go but to compress. This leads to a pressure jump, so that the temperature in the combustion chamber rises rapidly. The ignition temperature of the diesel fuel-air mixture is 800°C. Accordingly, it is necessary to develop in the combustion chamber a pressure sufficient for such heating.

When the piston reaches TDC the nozzle must go off. Fuel oil flies out of it under high pressure. This should happen before the piston skips TDC, that is, with the so-called advance. This is necessary for two reasons. First, the nozzle has time to do most of its work before the next stroke. Secondly, the fuel must get into the combustion chamber when the air in it is at its maximum compression and warmed up.

It’s not so simple with injection, either. A few other prerequisites must be in place in addition to the advance. The main of them is that the fuel should be injected in the form of a fine mist, not dribbled sluggishly. This is to ensure that the fuel mixes better with the air and quickly turns into flammable vapors.

This is where the compression and injection cycle ends. If conditions are right, the fuel mixture is ignited as the piston reaches TDC.

Thrust

The ignited fuel-air mixture burns and forms gases. The temperature rises sharply, the gas volume increases, so that the pressure rises in the combustion chamber. The fuel has given up its energy. This energy in the form of pressure presses the piston and pushes it down. The engine starts. We hear a characteristic sound. If we don’t hear any, ignition has not taken place.

Exhaust

Converting the energy of the fuel into motion of the crankshaft, the piston passes the NTM. The discharge valve should open at this point. The piston coasts upward as inertia drives the combustion products through the exhaust port and muffler into the atmosphere. When the piston reaches TDC, the exhaust valve must close, and does not open again until the next exhaust stroke.

On many diesel engines, the intake valve already “rushes” to open at the end of this cycle. This lets the combustion chamber “air out” and gets more air in the next intake stroke. This is why the valve setting should be done on the compression stroke when both valves are properly closed.

How to start a single axle tractor correctly. after winter, without a starter, new

Today, power tillers have become almost an integral part of agriculture. Many farmers have entrusted this machine with all the hardest and most exhausting work. Now it prepares the ground for planting crops, waters plants, digs up potatoes, transports cargo, and even looks after the territory of the homestead.

However, just like any other machine, power tillers need to be treated with care from the moment they are first started. If you want them to serve you as long as possible, you must know all the nuances of starting a power tiller.

In this article we will tell you about how to start a single-axle tractor correctly and how to do it after storage in winter. After all, if you start it incorrectly, you may have serious problems that will require the repair of the unit.

How to start a single axle tractor correctly?

After you bought your single axle tractor, you should not start it up immediately, even if the consultants assure you that the equipment is fully operational. You need to start with the preparatory work.

To do this, the first thing you need to do is to check the oil level in the engine. There has to be enough oil. If not, you need to add oil. If you start the engine without oil it will immediately fail. You can find power tillers, such as the Caiman, that have an oil level gauge on the market. If there is little or no lubricant, the engine simply will not start. This is very convenient and considerably prolongs the service life of your machine.

After that you need to add fuel. Check with your dealer or your owner’s manual to find out what type of gasoline is right for your power tool. If the machine has a two-stroke engine, then the fuel must be diluted with oil in a certain ratio. Never use fuel that is of poor quality or unsuitable for your power tool.

The final step in preparing the machine for start-up is to check all connections and fasteners. All the moving parts should not be tight. their work should be resilient but smooth.

Starting a diesel and gasoline power tiller is a little different. The gasoline unit is started in this way:

  • Open the gasoline faucet;
  • The choke lever should be in the “start” position;
  • The ignition must be off;
  • pump the mechanical starter a couple of times;
  • now you have to turn on the ignition;
  • pull the starter again.

If you have an electric starter, then you can turn on the ignition right away. The starter quickly pumps fuel into the carburetor.

With a diesel power tiller things are a little more complicated. The new machine is completely bled out, unless, of course, no one has started it. To pump it, you need to twist the starter. The process will be longer than starting a gasoline-powered machine, but eventually the single-axle tractor will start.

If you have a manual starter, you can yank it, but you can also start the single axle tractor another way. To do this you need to open the fuel tap, and from there to twist each connection to the nozzle. You unscrew the connection, wait for the fuel to flow, and screw it back on, moving on to the next.

When starting mechanically, you need to open all the taps and put the gas in the middle position. Having depressed the decompressor, pump a couple of times, holding it with your finger. Then lower the decompressor and pull it to its original position. Push it again and do not hold it, but pull the starter. The single axle tractor should start.

Starting a power tiller without a starter

In power tillers, some elements often fail. Starters are one of the first to break. This has no effect on how the machine works, nor even on how it starts. It is important only to know some secrets:

  • Dismantle the damaged part;
  • You will need a strong rope, which will be about 1 meter long;
  • At the place of the former starter is a round element, on the wall of which you can see a hole, in which and need to pull a rope and fasten it securely;
  • Wrap the rope around this round part several times. You should end up with a cable length of about 40 cm.

You have to pull the rope hard to start the engine. If it did not work the first time, you will have to repeat all the steps again, because the rope does not stay on the part.

Starting a power tiller after winter

Owners of power tillers often encounter this problem when the equipment does not want to start after winter. This is due to the storage conditions. If the machine was in a cold, wet room, you can end up with a number of serious damage.

You must completely change the oil and fuel before you start it for the first time in the spring. Make sure that the fluids are at ambient temperature. this is extremely important.

You may find that the single axle tractor refuses to start right away. And this is quite normal. Allow the machinery to warm up a little. It should also warm up after starting the engine.

If you still fail to start the motoblock, you need to perform these actions:

  • blow out the fuel system. There may have been residues of gasoline or diesel left in it;
  • check the spark plug. You can even clean the contact with a little sandpaper;
  • Check all the wires to make sure there are no breaks or damage.

Peculiarities of starting some models of power tillers

Different models of power tillers start differently. In order not to encounter difficulties, you should carefully read the manual, which will be described in detail.

So, to start the single-axle tractor “Neva”, you need to put the ignition switch in the “on” position. Then you open the gasoline cock and close the choke. The throttle grip should be at about ¾ of its maximum position. Pull the starter motor, then open the choke. If you start the single axle tractor in the cold season, then open the flap gradually.

The Ural single axle tractor is also started quite simply. The gear shift knob should be in neutral position and the gas tank should be open. Then close the throttle and air valve and then start the engine.

Preparing your power tiller for starting

Problems with starting the engine can occur not only with a second-hand motoblock and cultivator, but also with a newly purchased new one. Therefore, before starting a singleaxle tractor for the first time, be it Kaskad, Neva, Mole, Zubr, Kentavr, Khoper, Tarpan, Oka, Salyut you should read its manual, then carefully inspect all connections and, of course, check the oil level in the engine.

It is necessary to study the manual, drawn up by the manufacturer, in order to find out what working cycle the engine has: a four-stroke (like Forte, Centaur, Lifan, Zubr) or a two-stroke. It is important to know, because for models with a two-stroke motor (like the Mole cultivator) you need a special combustible mixture consisting in a certain proportion of gasoline and oil. Because of mismatched fuel the car will choke, and also the spark plugs and fuel line can suffer, which is fraught with gasoline pump failure and it is a direct way to an expensive repair in the service station. You can tell if the fuel is suitable for your motorcycle by the smoke. If the quality of the gasoline is poor, it will have a white color, as is the case with a strong incline of the machine. If you have extra fuel in your machine, change it if you think it might break down.

Fuel quality is just as important for a diesel power tiller. The engine does not start in winter or starts but soon shuts down if it is filled with summer fuel. This is because at low temperatures the fuel begins to thicken and clog the fuel line. In such cases the risk of breakdown increases. Choose the right fuel for your machine in cold weather.

Starting motorcycle equipment, both in summer and winter, should be done in a certain sequence. For example, to start the Mole motocultivator, the following procedure is carried out:

  • Open the petrol valve;
  • Put the choke lever in the “Choke” position;
  • Turn off the ignition and crank the motor several times with the manual starter starter;
  • Re-start the engine and put the lever in the “Run” position.

it is not uncommon for the power unit to start easily but stop after a few seconds. In that case you need to check the sump patency, the reason might be that the tap is clogged. then you clean it with gasoline.

To start machines with diesel engine (like Zubr, Kaskad, Centaur, Neva) will be a bit more difficult than to start the engine of the Mole. Start the diesel engine with the “bleeding” of the fuel line, i.e. with its clearing from air accumulation. To do this:

  • Open fuel tap;
  • Unscrew the connections of the fuel take-off channel until the fuel appears;
  • Tighten the connections and blow out the nozzles.

If the engine doesn’t run properly and the machine smokes a lot of white smoke after a few operations it’s because the grease is old and needs to be completely replaced. The diesel also fails to start because of the insufficient amount of oil, so do not forget to control this parameter.

Start of a power tiller after the winter or a long idle time also has its own nuances. In order to make the machine work, the following manipulations should be done:

Well, of course, before you start the motor equipment, whether it be Kentavr, Cascade, Neva, Patriot or Zubr, check all the connections, including transmission nodes, clutch, starting mechanisms, and if necessary carry out their adjustment.

Starting the engine without a starter

Quite often it is starters that fail first. And it can happen at the most inopportune moment. To avoid wasting time and money on a complete replacement of the part, you can start the engine without the starter.

To start the power tiller without the starter is enough to perform the following steps:

  • Remove the broken part;
  • Find a strong rope length of about a meter (can be removed from a broken starter);
  • In the place where the starter was, you will find a round metal part. On one of its walls there is a special hole. Thread the rope into it and secure it with a knot;
  • Wrap the rope around the part several times, so there is about 40 cm of rope left over.

This is how you change the starter. In order to start the engine, you must pull sharply on the rope, pulling it out completely. The wire should not stay in the part, so this procedure should be repeated each time you start the engine. Never wrap the rope around your hand or other objects. This can cause serious injury.

How to install an electric starter on a single axle tractor. Specialty Equipment

Moto-blocks are known for their design features. In particular by the fact that two starters are used at the same time.

The auxiliary or spring starter helps the main starter start up smoothly and quickly.

But if the auxiliary starter suddenly fails, you have to think about how to repair the manual starter. Perhaps even with their own hands.

By the way, the spring option is not the only. The manual starter for a single-axle tractor is quite common, it is common in Russia. It is much easier to use. It is easier to install, even if the user does it with his own hands. It has quite an uncomplicated design:

  • drum housing;
  • coil;
  • Spring, or rather, the whole two: large and small;
  • washer;
  • cord;
  • tongues;
  • bolts and nuts, without which it is impossible to assemble either a mechanical or an electric starter.

When assembled, it looks as follows: the cord is attached to the spool, and it is fixed to the core of the drum housing. There is a special space inside the drum, where a large spring is located around the axis. It is it that is responsible for ensuring that after cranking the starter returns to its previous position.

Preparing the power tiller to start

Difficulties with starting the engine may appear not only in used power tillers and cultivators, but also in new ones that have just been purchased from the dealership. For this reason, before starting the mini-tractor for the first time, you should read the instructions to it, then carefully examine all the connections and, of course, check the oil level in the engine.

Study the annotation, compiled by the manufacturer, should be in order to find out what the working revolution of the motor: four-stroke or two-stroke. It is important to understand this, because modifications with a two-stroke engine (like the Mole cultivator) require a special combustible mixture consisting of a mixture of fuel and oil in a special proportion.

It is also possible to damage spark plugs and fuel line, which is fraught with gasoline pump failure, and that is a direct way to an expensive repair in the service station. It is possible to determine whether the fuel is suitable for the motor vehicle, judging by the smoke that appears. If the fuel quality is poor, it will have a white tone, as happens when the vehicle is heavily tilted.

The fuel quality is also important for a diesel engine tractor. It does not start in winter. or starts, but soon freezes. if his engine is filled with summer diesel, since at low temperatures, it begins to thicken and clog the fuel pipe.

The engine should be started in both summer and winter in the correct order. For example, to start the Krot motocultivator, this order of operations is carried out:

  • open the petrol valve;
  • set the choke motor to the “Choke” state;
  • turn off the ignition and crank the engine several times with the manual starter
  • Re-start the engine and put it into “Run.

Often there are conditions when the power unit starts easily, but freezes after a couple of seconds. Check that the sump is in good condition. If the reason is that the crane is dirty, then it is cleaned with gasoline.

To start the motor equipment with a diesel engine will be somewhat more difficult. Start the diesel engine with “bleeding” the fuel line, ie with ridding it of air accumulation. To do this:

  • open the fuel tap;
  • untwist the flare duct connections until fuel comes out;
  • Twist connections and blow out all nozzles.

If after the operations the engine does not work properly, and the special equipment begins to smoke, then the reason is the old grease and it must be changed completely. The machine does not start because the volume of the oil fluid is insufficient, so do not forget to control this parameter.

Starting the power tiller after the winter or a long idle time also has its own nuances. In order to get the unit in the working position, the following operations are carried out:

  • open the petrol valve;
  • Check that the power is on;
  • conduct a check on the presence of lubricant;
  • Give gas to about half.

Before you power up your power tool, check all connections, including the transmission, clutch and starting mechanisms and adjust them as necessary.

Repair of assemblies and mechanisms

Starting a diesel power tiller after purchase can be tricky. The matter is that air gets into the fuel system. If the engine can’t be started with a long cranking, the air lock should be bled. To do this, open the diesel fuel tap and unscrew all connections along the way of fuel channels. The final flushing point are the injectors.

For the combustion engine to start, a number of requirements must be met. Let’s list them in order:

Performance of the listed conditions guarantees the start of any engine.

Difficulties at start indicate failure of nodes and mechanisms. The success of the repair depends on the correct diagnostics. If defects are detected, the repair of the diesel power tiller. Maintenance and minor repairs can be done on your own. You will need a set of wrenches, a locksmith’s tool and capable hands.

At the stage of fuel mixture preparation the following mishaps are possible:

  • The air filter is leaking air;
  • Clogged hole in the tank lid;
  • the fuel supply line is clogged;
  • the carburetor is broken.

After a series of unsuccessful starts, it is useful to unscrew the spark plug. The working part can be flooded with fuel. Dry the part. Next, pump the cylinder through the hole. Screw in the spark plug and start again.

If the spark plug is dry, it means that there is no fuel in the combustion chamber. Let’s perform a series of actions in sequence to restore the feeding system:

  • Drain the old gasoline;
  • flush the tank;
  • clean the filter from dirt;
  • Blow out the fuel supply hose;
  • blow out the carburetor jets;
  • Fill the tank with clean gasoline;
  • open the faucet;
  • Clean the breather duct in the cap.

Why doesn’t the Cascade single axle tractor start??

Nowadays, special equipment is often used in agriculture and horticulture. Here separately, such equipment as a single-axle tractor is singled out. These devices allow you to quickly and efficiently work the ground. However, like any kind of machinery, such equipment can also break down. In this case, it is required to consider how to act correctly if the single-axle tractor Agro malfunctions and does not start.There are several reasons for the failure of the engine in this motoblock

Why the engine doesn’t start

The reasons for which this device may not start, quite a lot. In this case, it is necessary to break down the main points that prevent the engine from starting:

  • No spark on the motoblock (the spark plug does not receive the appropriate power from the coil).
  • The motor does not have the necessary compression to start and burn the fuel.
  • There are gaps in the cylinder, which cause the spark plug to be blocked by oil and prevents fuel from igniting.
  • The necessary amount of fuel mixture is not delivered to the engine for its direct start.
  • serious engine failures associated with stuck rings, broken connecting rods or valves.

Currently, there are a lot of engine failures that prevent it from starting, but we should consider the most important of them, which the owner of the equipment can eliminate on their own.

In this video you will learn how to fix a single-axle tractor Agro:

Important! Any malfunction regarding no spark, popping, jerky operation or transmission malfunctions can be corrected yourself, provided you have the proper skills and knowledge.

Eliminate such faults with your own hands

Earlier we considered why the motocultivator does not start, and what are the reasons for the lack of spark in the motoblock. Next, consider the moment with the independent elimination of the following series of defects:

  • no spark (the problem lies in the spark plug, ignition coil failure, in any case, you can fix the problem yourself);
  • Not switching gears (the breakdown is associated with the clutch, or the gears are out of order);
  • the single-axle tractor works jerkily (uneven combustion of the fuel mixture or overflow of gasoline).

In each individual case, the work is done with a particular power unit, which is mounted on a single-axle tractor. There are a number of nuances and peculiarities of the mechanism should be taken into account here.

Important! Modern devices are complex mechanisms with many components, which is why, before trying to eliminate the defect, it is necessary to understand what may cause it.

No spark

Lack of ignition. this is the most common phenomenon. There may be many reasons for this, but it is necessary to consider situations where there is no need to repair the engine:

  • The spark plug is out of order. In this case the problem can be easily solved. first of all, it is necessary to understand what is the cause of the spark plug failure. This requires taking a new element and checking it for ignition. If the spark is present, you can limit yourself to the usual replacement of this consumable component. Provided that this is not the cause, it is also recommended to change the oil and air filter.
  • The ignition coil is out of order. Here it is required, as in the previous case, on a new spark plug to check the presence of the spark. If there is no ignition, the coil or the high-voltage wire may have failed. Repair consists in the usual replacement of these components. After installing the new parts, as a rule, everything starts working properly.

If the spark plug is the cause, the problem may also lie in the engine itself. If there are scuffs in the cylinder, the candle will constantly be covered with oil, due to which it will have a characteristic black fouling.

Important! If the problem is the lack of ignition in the engine itself, then it must be replaced or overhauled, this work must be done by a specialist.

Sparks on this power tiller may not be for several reasons

The gears do not turn on

If the gears do not engage, the transmission does not allow the inclusion of gears, there may be several reasons. In this case, consider the defects that prevent the movement of switching gears, which you can fix yourself:

  • If the box used to engage well, and soon stopped working properly, as well as hear a metal noise, the problem is most likely in the lack of lubrication (a comprehensive maintenance of the transmission with the replacement of consumables);
  • The problem may be related to the clutch (to eliminate the defect it is required to replace this mechanism on the motoblock, as a rule, this malfunction is inherent in the long-term development, which is accompanied by increasingly heavy gear shifting, in addition, when switching to a gear, the gearbox can kick).

Another common problem with the transmission. this failure of the transmission gears. To eliminate such a malfunction is extremely difficult, because this requires complete removal of the transmission, and then subject it to rebuild. Also, as an option. to replace the transmission, but it is a significant cost.

Important! Provided that the skills of working with gearboxes are absent, it is recommended to refuse to carry out the reassembly yourself, as there is a chance to further aggravate the situation (such work should be carried out by a specialist).
