First remove the clutch cup. She is attached to the crankshaft with a screw. This screw is not visible, but it is there. In short, in the square hole, which includes the shaft of the bar, you need to insert a standard key-star (it comes with a scythe). Remove the cup, the clutch itself unscrewed with my hand.

How to remove clutch on a trimmer / how to remove a clutch on a benzocosa

  • To remove the clutch on the trimmer (removing the clutch on the gas station similarly), you must first remove the muffler cover, the metal stand, the starter cover and the cylinder cover so that they do not interfere with the grip cover of the trimmer for the grass.
  • Remove the shock absorber lid (having twisted two side screws), release a bolt, tightening the shock absorber and remove the pipe from the shock absorber.
  • We twist 3 or 4 bolts and remove the clutch cover.
  • We evaluate the wear of the pads and the clutch drum, we look at whether the spring is broken, we examine the condition of the bearing.
  • To replace, for example, the pads (weights) of the gripping trimmer for the grass, you need to remove the clutch spring, and then unscrew the bolts on the blocks (if necessary, after stagnating the knee-deep, stuffing the rope into the candle hole when the piston is in the NMT).

During the work of the trimmer for grass at idle, the clutch pads, although they rotate with the crankshaft, do not touch the clutch drum, as they are compressed by the spring and do not transmit torque from the motor to cutting equipment.

During the engine operation at revolutions above the idle (above 4000 rpm), the clutch loads under the influence of centrifugal force are unclenched (overcoming the force of the spring) and resting their external friction surface on the inner surface of the clutch drum, begin to rotate it, thereby transmitting the torque from the moment from the moment from the moment motor for cutting equipment of a trimmer for grass (or lawn mowing).

16 Thoughts about “Clutch of a trimmer for grass. malfunctions, causes and methods of elimination”

Hello, tell me why the clutch at the benzos rings the springs of Grace

I think that the clutch spring burst, the clutch spring of the trimmer for the grass often breaks because:

Wear of the pads, and maybe the clutch drum (which leads to stretching the spring during operation longer than the norm).

Uneven wear of the pads with some side (it transfers the spring).

Wear of the bushing bushings (causing the backlash of the pads and skewing of the spring).

Check whether the bolts of fastening the pads are tightened and whether the grip of the trimmer grip is staggering for the grass.

Not the correct installation of the clutch spring cannot be inserted into the hole, pull the spring, trying to put the spring’s ear in the hole in the block. It is necessary to remove the pads from the braids for the grass, hook the ends of the spring behind the holes in the blocks, put the pads in a normal position to each other (in the hands with a dressed spring), and then install the collected pads with a spring on a braid and tighten the fasteners (special bolts, preferably new so that they do not unscrew during work).

Not proper operation of a trimmer for grass. The manner of mowing pressed on gas, released gas, pressed gas, released gas as a result of overheating of the clutch and springs, which leads to its fragility and premature wear of the trimmer grip for grass. It is necessary, during the mowing, try to keep the same engine speed, and the gas key only adjust the revolutions depending on the load (depending on the density of the grass).

The chainsaw is stalled and not start

If the tool is stalled and not starting to start, it is worth checking the presence of fuel in the tank. Oddly enough, it sounds, but many people forget about this and, if such a situation arises, they immediately try to repair the tool, which can lead to serious breakdowns.

In a situation when I drank it stalled, and there is still gasoline in the tank, you need to evaluate how the saw worked until this point. Maybe when working at the last moment there was an extraneous sound, rattle, ringing, power loss, or the tool stopped abruptly. All this will allow to pre.assess the situation.

The engine jammed

Quite often there is a situation when the saw worked and sharply stalled, the cause of which was the jamming of the engine, which in turn occurred as a result of a break in the piston skirt, destruction of the crankshaft bearing, the outbuilding ring of the piston fingers or the break of the piston ring.

The engine jamming is easy to determine if you pull the starter cord. In the case when the starter does not turn, most likely, it jammed, and further repair is possible only in the service center.

The cliff of the fuel wire

During the operation of the chainsaw, vibration occurs, which can cause damage or breakthrough of the fuel line of the chainsaw. In this case, the chainsaw will stall and it will be impossible to start the launch. To diagnose a malfunction, you need to conduct an inspection and determine the presence of fuel fuel.

Overheat

Overheating of the engine during operation may cause the saw to be stalled and will not start. Overheating is quite dangerous, as it can cause melting the piston in the cylinder and jamming of the engine. In the first cases of overheating, it is worth diagnosing the tool for the availability of extraneous air leaks to the engine, and adjusting the carburetor.

Air leakage, as well as the correct adjustment of the carburetor affects the maximum number of engine speeds and its lubricant, which in turn causes overheating and shaking the tool.

What are the overlays

By the method of manufacturing the lining are classified as follows:

  • molded from mass;
  • cardboard-backelite (pressed from cardboard) with special impregnation;
  • weaned-backelite, obtained from a textile tape with impregnation;
  • spiral-waited, obtained from a reinforced thread with impregnation;
  • Ellipsonavian, also obtained from a reinforced thread, but laid down in another, more rational way.

What are the advantages of a particular way? If we consider the cost, then the most cheap linings of the first three groups are obtained.

But the appearance of high.speed engines increased the requirements for the dynamic strength of the linings. It is clear that a modern car, which is gaining high speed in a matter of seconds, should have a clutch protected from the “puppy”.

This phenomenon is best opposed by the overlays of the fourth and fifth groups. A frame of thread reinforced with brass or copper wire and connected by a special composition, perfectly copes with inertial loads. About this. in the next sections.

How to replace the clutch on a trimmer correctly

Having replaced a large number of clutch on various trimmers, I chose the most convenient option for its replacement. And about this my video, I hope this will help you when repairing.

There was a small problem with the collection on the Redverg trimmer: when assembling at the factory under the head of one of the screws, more than one spring washer was laid, but two; Because of this, one of the pads was clamped, and it did not return to its original position under the influence of the spring.I took the rope with a thickness with a little finger, filled it in a candle hole when the piston was in the NMT; In my opinion, there was quite a lot, only nodes did not do. In short, I did a clamp, but at the same time the piston soaked this rope so that in the cylinder there was a lot of strokes left from it, and the piston began to wedge in a certain position. I had to remove the casing and unscrew the cylinder to pull it out of there.And what did I do with this rope wrong? Maybe due to the fact that the ends were not melted, or there were no nodules? By the way, I did not understand why these nodules are needed.

1) So it is necessary to put the bolts on the thread lock or not. 2) what is the “standard” intercenter distance at the bolts. 52mm or 53mm ? Specifically, at Carver GBC-31f I roughly intended 53mm. But on sale I see only 52mm intercenter distance.

Simple, intelligible and no stiff stopors of the piston!

Thank you very much, for such and understandable OSB.

How to replace a clutch in a trimmer

Today we will figure out how to replace the clutch in the trimmer with our own hands. For example, take a trimmer for Echo grass, which our wonderful neighbor provided to us. He asked not to give his name, but we still thank him.

So, how to replace the clutch in the trimmer:

CAREFULLY! Before the launch, operation or maintenance of the engine or equipment, study the operating manual to avoid injuries or damage to property. Contact the authorized workshop if you are not sure of any procedure or have additional questions.

About a car wash

This article will be devoted to sinks, their design and operation.

The choice of motoblocks. Questions and fasteners

In this article I will try to answer the questions that customers most often ask. I will mention those moments that should be considered when choosing and checking equipment.

Chainsaw. How to unscrew the clutch.

Damage caused by the incorrect actions of the owners of the tool when weakening adhesion is often found. How to do this, described in the article.

This problem arises every time when there is a need to remove the star and / or clutch chainship.

You can find a lot of video and text materials on this topic on the Internet. If desired, all this is easy to find. It is always useful to find the necessary information in the tool guide.

Each saw model has its own characteristics when performing this procedure. Therefore, we describe this process from a general ideological point of view.

Remove the brake chain cover. First, pull the brake handle over yourself. This must be done so that the brake strip does not touch the clutch cup. Then unscrew the two nuts holding the lid. Release a mechanical chain tensioner. Loosen the chain and tire tension. Then completely unscrew the two nuts and remove the brake cover of the circuit.

Remove the tire and circuit, remove the dirt, if any.

Remove the spark plug from the spark plug in the cylinder.

Next, you need to block the piston in the cylinder. To do this, rotate the clutch, observe the movement of the piston up. In most cases, as soon as the piston blocks the exhaust hole, lower any suitable cable into the spark plug in an amount sufficient to prevent further movement of the piston upwards. To increase the effect, you can apply simple nodes to the rope. Remember that the rope should be extended back. So do not miss the other end;)

Now you can unscrew the nut on the clutch. The most important thing you need to remember. turn the key clockwise to unscrew it to unscrew it. The key that comes with the saw. This is a tool. It is not recommended to unscrew the clutch with a chisel and a hammer. bring down the border. This is the last remedy.

Then remove the clutch and drum using a gear wheel.

Assess the condition of the needle bearing.

Here are some things that you need to keep in mind:

Design features

Champion 137 does not have any design features, everything is done as simple and cheap as possible. The usual engine is a two.stroke, a membrane carburetor, a starter without additional springs, but this does not mean that the chainsaw is bad. It is nice to hold it in her hands and it starts no worse than the household model Khuskvarnaya, for example, 236th.

There are still minor improvements, this is an additional fuel pump, which is designed to facilitate the launch after prolonged downtime, as well as the chain tension regulator installed on the side cover, which is quite convenient.

In the latest champion 137, the manufacturer added a hatch of the upper cover, through which you can, without the use of an additional tool, gain access to the air filter and candle. Comfortable? Of course convenient, t. to. Earlier it was necessary every time you need to check the cleanliness of the air filter, spin 4 screws of fastening of the upper cover and remove it completely.

The wood control elements are made as simple as possible, there are no combined levers and other things. A separate air damper control lever, which is installed on the case to the right of the rear handle. Reliable and non.expensive button ignition switch.

At first glance at the saw, it becomes clear that this is a budget option without any bells and whistles. Below you can watch the video test of the Champion 137 saw.

Clutch relief on the chainsaws of Stihl and Dolmar

Of course, you noticed that chainsaws can have different designs of transmitting devices. Up. The clutch relief instructions on the drum on which the asterisk is inside. This device is available in most chainsaws, but not on Stihl tools. The chainsaws from the famous manufacturer are equipped with a drum on which the star is located outside. It looks like in the photo below.

A different location of the star does not mean that the tool is equipped with another clutch mechanism. However, this suggests that the principle of lifting the clutch differs from the above instructions. Therefore, we will learn how to remove the clutch on the stihl, Dolmar and others on which the star is located outside.

  • You must also first remove the cover and wheel to provide access to clutch
  • Unscrew the spark plug and fix the piston using a special key or cord.
  • Then proceed to remove the stars and drum. To do this, with a screwdriver, break the ring and tighten it
  • The drum with the bearing is dismantled
  • Using the key “19” (included in the tool kit), unscrew the nut with the left thread connected to the mechanism. Unscrew
  • After that, you can carry out appropriate repair or replacement of the part

The installation of a new or repaired part is carried out in the manner of removal. The procedure is almost the same as in the first version, with the exception of some functions. If you only need to replace the drum or star, then you will not need to remove the clutch, unlike the version with the inner star.

How to disassemble the head of a trimmer for grass

One of the common devices created for haircuts of grass

, is a trimmer for grass. It is very easy to work and maintained. That’s why it became popular in the middle of the population. Its significant advantage is small weight. Even a child can cope with such equipment.

One of the common devices created for haircuts of grass is a trimmer for grass. It is very easy to work and maintained. That’s why it became popular in the middle of the population. Its significant advantage is small weight. Even a child can cope with such equipment.

What it is?

A trimmer for grass consists of a cutting element, a bar, a motor and a handle with a control mechanism. It is intended for haircuts of grass

in garden areas, also to create an impeccable lawn. Thanks to its own compactness, the device makes the necessary work in those places where the lawn mower cannot get. Apart from the grass, the trimmer for the grass is designed to mow branches of trees and shrubs, also creating flower beds. Such equipment is not always used for the lawn, because the length of the grass will have different heights.

Specifications

The main technical features of the trimmer for grass are:

  • Power;
  • Equipment weight;
  • Type of power (from the network or using the battery);
  • Placement of the motor (at the top or down);
  • Type of cutting element;
  • Type of bar.

All this must be taken into account, take either another device.

How to choose the right?

Before buying this equipment, you need to realize for what purposes it will be used. For a huge section with an even lawn, it is better to purchase a light model with small power. If you need to improve the summer cottage, then you need to choose the model more powerful.

The scheme of a two.stroke character.

To date, the chainsaws are equipped with electronic ignition units that do not require adjustment and cleaning. The ignition system includes a flywheel with magnets, a module with an electronic system, a light of ignition and a high.voltage wire.

The starter installed on the device is used to start the saw engine, turning the crankshaft. The starter mechanism includes the following elements:

Having sharply pulling the cable, the starter’s rates hooks the teeth of the crankshaft, which leads to its rotation. The return spring is designed to return the cable to its original position. A certain force is required to start the power plant, since the engine starts only with a certain speed of crankshaft rotation.

The design of the chainsaw is equipped with a centrifugal clutch, which is automatically turned on, completely depending on the speed of rotation of the crankshaft of the engine.

At low speeds, the elements are installed in the clutch basket and have special overlays, the springs are attracted to the center of the shaft. This position of elements prevents the transmission of rotational motion from the crankshaft to the asterisk. Having reached a certain number of revolutions of the power plant, elements with special overlays are accelerated and clamped on the clutch drum, transmitting the rotation of the chain. The main feature of such a clutch is that when the chain saw stops, it begins to slide, which avoids damage to the power plant and mechanisms that transmit the movement of the chain. Quite often intensive use of clutches, it is necessary to prevent and repair. To do this, the clutch is disassembled.

This constructive element is expensive and, in turn, requires regular replacement or repair.

File position when sharpening a chain of a chainsaw.

The main reason for the failure of this device is the wear of the sprocket teeth. If the drum is monolithic, then the chain cuts the asterisk. Such a drum should be replaced. Some drum installations have a replaceable head and are replaced during the repair, and the drum remains in normal working condition.

If you need to fix the chainsaw, the question arises of how to disassemble the clutch. If there is a service center, it is best to consult with a specialist, but in the absence of the latter, the removal and repair procedure can be performed independently. This operation is simple, and almost everyone can perform it using suitable tools. Almost every model of this tool has its own nuances of dismantling, but the total sequence of actions is the same for any model.

First, remove the brake chain cover. To do this, pull the handle over yourself. This is done so that the belt does not touch the clutch cup. After that, the nuts for attaching the cover and tensioner of the chain are weakened.

The weakening of the tensioner weakens the chain and tire. Then the nuts of the brake cover are unscrewed, after which the lid is completely removed.

At the second stage, the guide tire and the chain are dismantled and the pollution is removed.

The next stage of disassembly is the inversion of candles of the GBC. Then the piston is blocked in the cylinder. To do this, the crankshaft rotates and, after closing the exhaust opening, a piece of the cylinder drops into the cylinder, which prevents further movement of the piston. After the repair, the cable is pulled at the other end.

The fourth stage of disassembly. This is a direct pashing of clutch. First you need to unscrew the nut on the clutch. Keep in mind that it has a left thread, and when you unscrew it, you need to turn the key clockwise. The key that goes with the accessory of the chainsaw is used to work.

How a clutch works! (Animation) | Clutch, How does it work ? | single plate friction clutch working

Unscrew the nut, disconnect the clutch and inspect the sprocket of the drive for wear. Then, after inspecting the drum and asterisk, the condition of the needle bearing is checked. If necessary, worn objects should be replaced.

When repairing clutch, some nuances should be taken into account:

  • On some modifications and models of the chainsaws between the puck and the leading star is the puck. If this element is disassembled, the washer should be established in the position in which it was previously. This washer can sometimes be installed between the engine and the cup.
  • Some models of oil pump drives have a special spring. He transfers rotation from the sprocket to the oil pump drive. The correct installation of this spring when assembling the device is very important. With improper installation, the oil pump stops supplying oil for lubrication of the circuit. What can lead to expensive repairs.

After the repair work, before using the chainsaw for its intended purpose, it is necessary to check the operation of the oil pump and its supply of oil for lubrication of the saw chain and the mechanisms of the guides.

Clutch of a chainsaw. malfunctions, causes and solutions

1) malfunction of the chainsaw: the chain rotates almost constantly (the engine may not work stable). Malfunctions: the clutch spring burst. Self.propelled chainsaw: replace the broken clutch spring with a new one (see. “How to remove the clutch of a chainsaw” below). Huskvarna chainsaws have one clutch spring and two scales, quiet chainsaws have three clutch springs and three scales (cam, sectors). If you cannot find the clutch spring itself, you will have to replace the whole clutch.

2) malfunction of the chainsaw: the chain rotates almost constantly, sometimes strange sounds are heard in the clutch.

Causes of the malfunction: the cliff of the clutch fist broke (due to overheating), and the clutch spring flew off. Blue clutch fists indicate overheating. Even when rupture of clutch, overheating can occur if you use a chainsaw or chain with a chainsaw. Self.propelled chainsaw: replace the clutch node (see. “How to remove the clutch of a chainsaw” below) to obtain more detailed information.

How to remove clutch on a trimmer / how to remove a clutch on a benzocosa

  • To remove the clutch on the trimmer (removing the clutch on the gas station similarly), you must first remove the muffler cover, the metal stand, the starter cover and the cylinder cover so that they do not interfere with the grip cover of the trimmer for the grass.
  • Remove the shock absorber lid (having twisted two side screws), release a bolt, tightening the shock absorber and remove the pipe from the shock absorber.
  • We twist 3 or 4 bolts and remove the clutch cover.
  • We evaluate the wear of the pads and the clutch drum, we look at whether the spring is broken, we examine the condition of the bearing.
  • To replace, for example, the pads (weights) of the gripping trimmer for the grass, you need to remove the clutch spring, and then unscrew the bolts on the blocks (if necessary, after stagnating the knee-deep, stuffing the rope into the candle hole when the piston is in the NMT).

The principle of the centrifugal adhesion of the trimmer for grass

During the work of the trimmer for grass at idle, the clutch pads, although they rotate with the crankshaft, do not touch the clutch drum, as they are compressed by the spring and do not transmit torque from the motor to cutting equipment.

During the engine operation at revolutions above the idle (above 4000 rpm), the clutch loads under the influence of centrifugal force are unclenched (overcoming the force of the spring) and resting their external friction surface on the inner surface of the clutch drum, begin to rotate it, thereby transmitting the torque from the moment from the moment from the moment motor for cutting equipment of a trimmer for grass (or lawn mowing).

16 Thoughts about “Clutch of a trimmer for grass. malfunctions, causes and methods of elimination”

Hello, tell me why the clutch at the benzos rings the springs of Grace

I think that the clutch spring burst, the clutch spring of the trimmer for the grass often breaks because:

Wear of the pads, and maybe the clutch drum (which leads to stretching the spring during operation longer than the norm).

Uneven wear of the pads with some side (it transfers the spring).

Wear of the bushing bushings (causing the backlash of the pads and skewing of the spring).

Check whether the bolts of fastening the pads are tightened and whether the grip of the trimmer grip is staggering for the grass.

Not the correct installation of the clutch spring cannot be inserted into the hole, pull the spring, trying to put the spring’s ear in the hole in the block. It is necessary to remove the pads from the braids for the grass, hook the ends of the spring behind the holes in the blocks, put the pads in a normal position to each other (in the hands with a dressed spring), and then install the collected pads with a spring on a braid and tighten the fasteners (special bolts, preferably new so that they do not unscrew during work).

Not proper operation of a trimmer for grass. The manner of mowing pressed on gas, released gas, pressed gas, released gas as a result of overheating of the clutch and springs, which leads to its fragility and premature wear of the trimmer grip for grass. It is necessary, during the mowing, try to keep the same engine speed, and the gas key only adjust the revolutions depending on the load (depending on the density of the grass).

Replacing a clutch coupling on a hammer MTK 28 motorcycle

I hope I helped. The first three points are treated by replacing the pads or replacing the grip of the trimmer for the grass assembly.

Tell me, but the clutch pads can somehow be restored (overlays are erased). On rivet, glue, and from what material to make a lining. Or where to buy pads with the size of the diameter of the pads assembled-58mm, the axial interb.40mm.

A similar story is absolutely! There is nowhere to buy, but how and what to glue on the pads of the mind I will not know. I want, to an extreme, to block the clutch and work without it. Kuzmich.

Kuzmich, and buy a clutch in an online store? Introduce the word trimmer for the grass to buy and look for your adhesion to the trammer for the grass in the search bar. If there is no precisely your clutch, you are contacting (calling up, writing off) with the sales consultant or the manager of the online store and they will be happy to select or order the right clutch for a trimmer for grass. If they do not help in one store, communicate with another, and t.D., Until you find the necessary iron! The main thing is not to retreat!

Now on the Internet, I think, you can even buy an international space station in a disassembled form. In addition, the Internet is cheaper than in ground stores (maybe several times). And immediately you can find out the methods and cost of delivery (also not expensive). The shortcomings of the purchase in the online store are that the goods must not touch/smell before the purchase and you have to wait for the ordered goods for several days, and if from abroad, you will have to wait from 2 weeks to 2 months.

How to restore a clutch for a trimmer for grass I will try to figure it out in the near future and unsubscribe here.
