Replacement of the bearing on the gasoline Hitachi. How much will the repair of the trimmer for the grass cost?

Hitachi trimmer does not develop a moment

I want to share my experience to restore the necessary power of a trimmer for grass with a gasoline engine.

Once in early June, I began to notice that my trimmer for the grass of the GT22GES model (manufacturer “ECHO”) began to lose its former power.

In the process of working with the grass, even with a slight increase in the load (grass higher and thoroughly), the turnover fell and the efficiency of the work was not the same as it was previously.

Previously, a trimmer for the grass did not notice such obstacles at all. With a sharp press on the “gashter” without load, the turnover increased slowly, as if reluctantly.

I took the user guide for a trimmer for the grass, found in it the section “malfunctions and their elimination”. I chose a suitable malfunction in the table, which is described something like this: “The engine is poorly accelerated or fades”.

Among the possible causes are pollution of the air filter, fuel filter, clogging of the drainage opening of the fuel tank, the spark plug, carburetor, clogging of the cooling system, clogging of the exhaust channel or silencer.

As it turned out, the list of possible reasons is extensive. where to start?

First, the air filter, a drainage hole, an air radiator looked visually, all this was in normal condition.

Then I decided to look from the end of the list, that is, check the exhaust system. the exhaust channel and muffler.

To do this, he took off the candle tip, unscrewed 3 screws and removed the plastic protective lid of the muffler (in the drawing in the manual under 5)

Then unscrewing two long screws, he carefully removed the muffler, so as not to damage the two gaskets that are present there

The foreboding did not deceive me. The output channel of the engine cylinder (through which exhaust gases emerge from the cylinder) was 30. 40 percent by a pledged.

So this is the reason for the disorder of the work of my trimmer for the grass!

Caution, so as not to damage the piston surface and prevent foreign products from entering the cylinder (in other words, the same carrier), I completely cleaned the exhaust channel from the carrier, carefully blew the channel using the pump. I used a knife as a tool (but only with the edge of the channel), and in the depths of the channel a wooden and plastic spatula of a suitable size

I used a knife as a tool (but only with the edge of the channel), and in the depths of the channel a wooden and plastic spatula of a suitable size.

The muffler was quite pure and inside and outside.

After the assembly, he started a trimmer for the grass, warmed up a little and tried to mow-the engine earned like new, the power increased noticeably, the grass does not mow, but cuts (fishing line for 3 mm trimmer).

It’s nice that the device began to work excellent and is doubly pleased that he himself was able to find a malfunction and eliminate it.

It is likely that such a problem can arise in other models of trimmers, because their design is approximately similar and all trimmers for grass have a graduation channel and muffler.

What breakdowns are in the gearbox, how to eliminate them

Consider which culprits of the breakdown are possible, and try to remove them.

The transfer node often overheats. The reason for the problem may be the use of poor.quality lubricant material purchased in unverified stores or in spontaneous markets. Perhaps the lack of lubrication is possible. The solution in this case is to apply a quality product and carefully lubricate all surfaces.

Also, overheating of this node is possible due to the installation of new gears that should be worn out. To fix this problem, work with the tool not too actively, do not overload the braid, make frequent breaks to cool down the device.

Когда вал вращается – появляется люфт и стук, вал стопорится или заклинивается. This definitely means that some kind of bearing has worn out, it is required to replace it with a new.

The transmission mechanism is kept unstable or even flies out of the bar. it has a damaged case, it is necessary to make a complete replacement. Sometimes, if the damage is not too significant, you can connect this place and a break about the help of a metal clamp.

The gearbox is not fixed with the pipe. So, the place on which the gearbox is attached is worn out. You can make a replacement of the bar, or just wrap it with insulating tape where you see the mount.

The shaft and the knife does not spin, or begins movement, and then with an increase in the load, the shaft stops. This indicates that the gear teeth are broken or worn out. In this case, replace the spoiled details.

Remove the worn bearing

The destruction of the bearing occurs as a result of the use of poor.quality lubrication, or it is completely absent. Also, often quite often the bearing fails if you operate too often in difficult conditions. This refers to the use of a device in areas with wood small plantations. The penetration of different small and large particles violates the integrity of the anthers.

To remove the bearing, disassemble the gearbox and apply a special puller. In its absence, take a hammer and an instruction. Work extremely carefully so as not to violate the integrity of the seat. To remove the bearing, it is not recommended to use heating before this. The danger is that there is a chance of changing the characteristics of operation.

Когда увеличивается нагрузка на косу, нож прекращает крутиться или совсем останавливается, и при этом вы слышите неприятный скрежет. The bearing is needed.

All problems in the gearbox without problems can be eliminated independently. Details that you are going to replace, try to purchase original, suitable for this brand of the lawn mower.

Replacing a heitachi grass trimmer bearing

We will try to answer the question: repair hitachi motorcosa with your own hands on the recommendations of a genuine master with the most detailed description.

There is only idle adjustment on the carburetor.

In my opinion, the best option is to open the instruction manual and find the “possible malfunctions” table, there is information about power (problems with it) regarding the engine.

These are problems with a carburetor, with a fuel filter, with an air filter, with a muffler and so on, including the fuel mixture (its quality).

It’s better not to start with everything at once, but from simple to complex.

Perhaps problems with the exhaust system.

Perhaps problems with the carburetor, it requires setting it up.

Drain the old fuel mixture and pour a new.

Remove the air filter, get a trimmer for the grass without it, if everything is in order, then the problem is precisely in it.

There is a special grid in the muffler (sparking), in principle, you yourself wrote about it yourself, some users immediately remove it from the new trimmer for the grass, of course you can “tinker” with it, rinse in gasoline and put in place.

The trimmer for grass does not gain momentum, a very common inconsistent and of course does not always have a common solution.In this.

One of the probable and often enough circumstances that the engine begins to “suffocate”, turnover.

An indispensable tool for a modern summer resident or the owner of a private house is a lawn mower, which allows you to effectively and efficiently bring the adjacent territory in order. The period of active use of motorcycle is in late spring until October of the month. Modern units are equipped with powerful and hardy ICEs, enhanced transmission and main nodes. Despite this, physical wear, production marriage or improper exploitation leads to the failure of a trimmer for grass. In order to repair a trimmer for grass with your own hands, you must have at least basic knowledge in the field of technology and a little experience in its repair.

The main node of any gasoline tool is the internal combustion engine (ICE), which through various methods transmits a rotational moment to the executive body. In a modern benzocosa, a duralumin rod (pipe) is used as an element of the transmission between the motor and the trimmer head, inside of which the drive shaft is located.

Thanks to a highly reserved engine, the frequency of fishing line can reach 13 thousand revolutions per minute depending on the producer of the braid for grass. In order to exclude mechanical and temperature damage to the gearbox, a special opening is provided for the introduction of ointments in its body. As a facilitating headset for the owner, during prolonged work, all modos models are equipped with a strong belt over the shoulder.

Regardless of the manufacturer, almost every model comes with fishing line and steel knives.

The transverse section of PVC Lines for a trimmer for grass can vary from 1.5 to 3.0 mm.

Made from a durable polymer, during kosba it is subjected to intensive wear and, as a result, a break. Therefore, from time to time it is necessary to check the presence of a fishing line in the head and, if necessary, replace it. It is recommended to purchase an additional bobbin for quick replacement with a reel with a fishing line ending.

The trimmers presented today on the market for ICE grass are equipped with a D-shaped, U-shaped or T-shaped handle, where the main controls of the unit are located. For example, in a spit with a U-shaped handle key and a “stop/start” toggle switch are located on the right handle. In the D-shaped version of the gas control key, the gas adjustment key is located directly on the bar.

In view of the presence of many nodes and details, the repair of a trimmer for the grass with your own hands involves the elimination of breakdowns that prevent its normal operation. It should be noted the most basic malfunctions of gasoline cos:

There is no thematic video for this article.

  • The engine of the trimmer for the grass does not gain momentum;
  • Breakdown of the cylinder-piston group (CPG);
  • Ignition malfunctions;
  • There is no connection between the internal combustion engine and the trimmer head;
  • Mechanical knocks when operating the unit.
  • Repair of the CPG lawn mower

The main node of any internal combustion engine is the cylinder-piston group (CPG), which can fail due to wear of parts of parts or low quality of the fuel mixture.

Lubrication of the rubbing nodes in a benzos is carried out by adding a certain proportion of oil to gasoline. This process can be disturbed due to the old oil dropping in the form of sediment. In this situation, when the trimmer for the grass is launched, the motor overheats greatly and in a matter of minutes the most expensive breakdown occurs. To eliminate the malfunction, a complete replacement of the CPG, namely: piston, seals, cylinder and piston rings will be required. If you are not a technical engineering master and do not have experience with technicians, then the engine is unlikely to be corrected without the help of a specialist. In detail with the stages of repairing a piston trimmer for grass, you can find here.

When you fail to ignition of the lawn mower, a spark on a candle disappears and, as a result, there is no ignition of the fuel mixture.

How to Replace String trimmer Line in Under 30 Seconds.

It is important enough in the current situation not to rush with the replacement of the coil, since the cause of the breakdown may be in the absence of contact in the switch on the control handle.

An important point in the search for the ignition of a trimmer for the grass will be diagnosed with Sich, where the distance between the lateral and central electrode should be 0.5-0.7 mm. In addition, it is necessary to pay attention to the sealing ring of steel on a candle, the loss of integrity or the deformation of which can lead to etching of the combustion chamber and, as a result, reducing the power of a braid for grass.

If the replacement of the check of the electric circuit, candles and its contacts did not give positive results, then you should pay attention to the ignition module of the trimmer for the grass, namely to the gap with the flywheel. Regardless of the design features and the manufacturer of the lawn mower, the distance between the ignition coil and the flywheel should be no more than 0.2 mm. To restore the optimal value of the clearance, it will be necessary to relax the bolts of fastening the coil and a special measuring probe set the ignition of a trimmer for the grass.

In custody…

Having made sure that the gears, bearings, stop rings and the oil seal are in order, you can proceed to complete flushing and re.lubrication of the gearbox. In case of detection of damaged parts, they must be replaced with similar. Pay attention how many wear products are on the sides of the head body.

Air filter checking and cleaning

When the air filter is clogged, the air flow into the carburetor decreases greatly, which leads to re.enriching the mixture with gasoline, as well as to increase fuel consumption, loss of power on the bottoms, increased formation of soot in the combustion chamber. This is the most frequent reasons why the scooter is poorly gaining momentum.

We check the air filter first of all, when the scooter is detected by unstable operation

Filter extraction

If the scooter is unstable, first we check the air filter:

one.We extract the filter, carefully shooting along the way all the details that interfere with this process

2.We clean the filter body from pollution.

3.We dismantle the case, trying not to damage it.

four.We check the presence of damage: through holes, cracks, tears, insufficient fit to the lid or edges of the case.

6.If the filter is damaged or exceeded the service life, then we simply install a new one in its place. It makes no sense to spend time trying to restore it, it is economically impractical.

Cleaning the filter

Ways to clean the scooter air filter:

  • Washing the filter in gasoline. Gasoline change occurs at least 2 times. Complete drying is not required.
  • Washing the air filter of a scooter in water using ordinary detergents intended, for example, for washing dishes, and then dried until it dries completely. Drying should be natural, without heating.

We impregnate the filter with oil

After washing and drying the filter, it must be impregnated with special impregnation or engine oil. This will save your carburetor and CPG from small particles of dust that may remain on the surface of the filter. Without oil impregnation, the functionality of the filter is extremely small, so the entire surface of the filter should be covered with a thin, but visible layer of oil.

And you can just do with ordinary engine oil. But the use of special impregnation is more effective.

For the period of engine running (this is approximately the work of a trimmer for grass by 2-3 tanks) the amount of oil can be increased. For example, mix it with gasoline in a ratio of 30: 1.

A small amount of oil mixed with gasoline leads to increased wear of the cylinder.piston group. An excess of oil in the mixture, although not so fatal, is also harmful. Cooking piston rings, rapid formation of soot in the combustion chamber, and a drop in engine power may occur. In addition, the mesh screen of the muffler is closed. Therefore, some users (after the end of the warranty period for a trimmer for grass) recommend it to be dismantled.

Gasoline used in motorcycles. AI 92. The brand of gasoline is accurately prescribed in the operating instructions. Do not try to “force” the engine, filling the 95th gasoline into it. This can lead to overheating, unstable work of a trimmer for grass and breakdown.

It is not recommended to leave fuel in a trimmer tank for grass with a long break in operation. It is better to finish the working day by completely developing the entire mixture. If this is not done, then because gasoline from the engine will evaporate during the night, and the thin oil filter will remain, carburetor jacks may clog. This will cause difficulties the next engine start.

It is also necessary to observe safety precautions when storing fuel. Many pour gasoline into a plastic bottle of water. Is it worth doing so?
