How to disassemble the tire from the chainsaw. How to disassemble a Partner chainsaw

Chainsaw is a very useful thing in the household. After all, a lot of tasks of home construction, gardening and landscaping of territories are quickly and relatively easily solved with her. Chainsaws are a sufficiently capricious tool, but with proper handling, this is an indispensable assistant. Who has one vulnerable place: guide tire. It is on it that most of the operational loads account. And this means that the knowledge about why tires more often than other parts of the chainsaws are out of order and how to correctly replace them with the case of necessity, will help you save money and time with seasonal or design work with an instrument.

Fastening of the tire of the chainsaw

The tire and elements of its fastening belong to consumables. The wear of this node occurs both under the workload, and as a result of the incorrect operating mode. The presence of malfunctions in this area you will determine immediately. The tire will not be able to ensure normal tension, lubricant and smooth stroke of the chain, and its mount. fixing the axis of the cut relative to the tool body.

Working with a faulty tire is unsafe. Therefore, at the first signs of the canvas breakdown, you need to turn off the motor and find out what’s the matter. Knowing the constructive features of the tire and its fastening on your chainsaw will help successfully eliminate the cause of the malfunction.

The tire determines the axis and length of the cut, directing the chain. But the basis of the mechanism is still mounting. It is installed in the groove between the internal plate on the motor body and the outer plate located on the chain headset casing. The tire and casing are fixed using a bolt connection. This part of the mount is called the “engine knot”, and its shape and design depend on the chainsaw model. Tire fastening and leading stars are closed with a separate lid.

The leading links of the saw chain are installed in the guide groove on the edge of the tire and are brought into the hook with the leading star connected to the power of power selection. When weakening fixing bolts, the tire can move. The tension of the chain can be adjusted manually or, as on professional chainsaws, automatically. Finally, in the front of the tire mount there is an emphasis. It serves to reliable fixation of the axis of the cut when contacting a moving circuit with a tree.

The working tire should provide normal chain tension. To check it, you need to release the chain brake and pull the chain with your hand in the direction of its movement. If the chain does not move, then the fastening is too tight. It needs to be slightly released, after which the free stroke of the chain is again checked.

Weak tire places

The main parts of the tire. body and groove. The width of the latter is called a gap. The front of the saw tires is made of steel of increased strength. The body of the tire is also subjected to hardening.

Currently, there are various types of saw tires on sale, which differ in:

• length and width of the body;
• the size of the gap;
• the presence of a nozzle of increased strength on the front;
• the presence and type of the driven star hidden in the front of the tire body.

The shape of the shank and the location of the technological holes in the tires for most amateur and professional chainsaws are standard, but they can constructively divide them into open and closed.

It is obvious that the former are inferior to the reliability of the attachment to the body of the second, t.e. On the casing of the tires and the bolt compound are increased loads. It is also necessary to monitor the integrity of the teeth of the stars. when blunting or chip, it will quickly bring the leading links of the chain into unusable.

The tire of the chainsaw needs regular care. After each session of the work of its grooves, it must be cleaned of dirt and sawdust, otherwise the lubricant will not enter the chain. The wear of the tire groove should be uniform, so it should be turned over from time to time. In addition, before starting work, you always need to check the presence of oil on the body of the chain and in the gap.

than three chain sets with one tire are not recommended to use. During operation, the gap, despite all the strength of the metal of the tire body, expands, which leads to the appearance of the backlash when the chain moves and its sagging even with the extreme front position of the tire.

The driven star located in the front of the tire is lubricated separately. Oil there, unlike the rest of the guide groove, does not get. It is poured into special holes in the front of the tire, and if there is no stars, it is applied to the sock of the tire.

Replacing the tire of the chainsaw and elements of its fastening

To replace the mounting elements, tire and chain headset, it is necessary to disassemble the entire mounting mechanism. It will not prevent you from preparing a rectangular piece of fabric or cardboard in advance, as well as a free space on the table for disassembling the tool and temporary placement of the removed parts.

Replacing the mounting elements and tires of the chainsaw is necessary for:

• Critical wear of the landing groove or shank elements.
• Damage to the casing.
• Violation of fixing fixing bolts.
• Damage or deformation of the body of the tire.
• Abrasion or breakdown of the teeth of the leading and led stars.
• Damage to grooves for supplying lubrication to the chain.
• Wear of the chain tensioner.
• Wear of the landing groove and tire fixer.

with your own hands, sharpening, device, choose how to repair, installation

Chainsaws are a necessary thing in home and garden economy, which helps to quickly and efficiently perform various work with a tree. Like any electrical device, it periodically fails and requires diagnosis. The result of the latter event is often a conclusion about the need to repair the tire of the chainsaw. a mechanism experiencing most of the load during operation.

Device and principle of operation

To independently eliminate malfunctions, the owner will need good knowledge of the device of the motorcycle. This is a device operating due to an internal combustion engine with one cylinder. Fuel fluid. gasoline. The saw mechanism is moving due to a single.stage chain transmission, for safety it is closed by the casing.

The main structural elements are the air purification system, the chain mechanism, the engine, the tension device, the ignition elements, the flywheel and the coupling. Many small details connect the main nodes and contribute to the reliable operation of the device.

The properties of automatic centrifugal clutch depend on the number of revolutions of the power unit. A low speed of rotation does not transmit rotation to the drum. Only when a large number of revolutions reaches the centrifugal force exceeds the force of springs, causing rotation of the drum. A chain and asterisk located in front of.

Malfunctions and how to repair the tire

With your own hands, a detailed scheme and understanding of the main mechanisms of the device will be required to repair the chainsaws with your own hands. The guide tire and its fasteners are vulnerable, consumable parts experiencing the largest load. You can repair the chainsaw tire yourself or by contacting the service center. Damage and breakdowns in this area are indicated by the absence of normal tension, sharp or intermittent chain stroke, the inability to ensure normal lubrication and fastening of the axis of the cut with respect to the aggregate body. Types of breakdowns:

• The rear and front leading links are riveted. The reason is the discrepancy between the step of the star and the links of the chain, weak tension or wear of the star. The problem is solved by replacing or adjusting the mechanisms.
• The presence of broken or non.kissed links indicate a weak tension or a chain break.
• Rounded backs of the spouts occur with excessive length of the chain headset and a lack of oil.

How to hide

Periodic sharpening is a mandatory event necessary for the normal operation of the gas station. Methods of independent sharpening of the chain:

• The use of a file is a simple and common option that allows the event directly at the site of the sawing.
• The use of a special machine. The method is found in personal farming and service centers.
• With a corner grinder. Sharpening will require skills.

A special machine is the most effective method. But with the help of a file you can also achieve good results.

How to choose a tire

Tire choice is a responsible event, the result of which the work of the entire device depends. The installation of an inappropriate element not only leads to the failure of other details, but also unsafe for the operator. In order to competently select the complete, it will require data from the length, size, shape and parameters of the shank.

The size is determined by the types of work that you plan to do with a saw. Small dimensions are suitable for simple manipulations, sawing thin boards. The most powerful installations are useful for harvesting firewood from thick trees trunks.

How to install a tire on a chainsaw

Before removing the tire, it is recommended to check the availability of the necessary components and tools. The tire installation begins with a fast tension system of the circuit, then it is necessary to go to the side and front device. Compliance with the sequence will allow you to correctly assemble the mechanism and ensure the productive operation of the tool.

Typology of fosions of a chainsaw

Before disassemble the chainsaw, you need to correctly determine the type of breakdown. Any malfunction in the work of the saw is conditionally related to one of two types. First. engine breakdown. Problems arise in ignition systems, fuel supply, air supply, output of spent air mixtures, cylinder-piston group.

The second type. malfunctions in other unit systems. This is a breakdown of the emergency brake, clutch couplings, guide tires, lubricant and other parts.

A set of tools for repair:

Engine start: check the candles

If the chainsaw is not started, the first thing to do is check the presence of a fuel mixture in the tank. By the way, it must be prepared in the proportions specified by the engine manufacturer, otherwise the tool simply will not start.

After making sure that the fuel mixture is correct and is available, you should check the ignition system check. To do this, inspect the spark plug.

It indicates that the fuel mixture does not fall into the carburetor, which means the problem is not in ignition;

It is the result of an excess of the fuel mixture, which lies either in violation of the engine start algorithm, or in the irregular adjustment of the carburetor;

This is a signal about the presence of low.quality oil in the engine lubrication system, incorrect carburetor settings or about incorrectly prepared fuel mixture.

If the candle is sprayed with fuel, after removing it must be thoroughly wiped. You should also clean the fuel supply system. To do this, it overlaps, after which the starter turns on. The candle covered with soot must be carefully cleaned with the help of an awl and emery.

When checking candles, attention should be paid to the distance between the electrodes (the normal gap is 0.5-0.65 mm), as well as the state of the gasket and the presence of a spark. The damaged or worn gasket will have to be replaced, and the spark can be checked by putting on the ignition cable by connecting the cylinder and a candle nut and starting the starter.

Additionally: Rotor disk (KD-1.5) bush at the price of the manufacturer

If the discharge does not occur, the candle needs to be replaced. In that case, if the spark does not appear with a new candle, then the problem is connected with the high.voltage wire or in it.

How to disassemble a chainsaw: step.by.step process with photo and video

Full lighting of the design of a multifaceted mechanism based on the work of a two.stroke internal combustion engine. From the air filter cover to the crankcase sewnes. we carry out a complete, step.by.step analysis of the gasoline saw system, via screws, with a specific example. For information and compression, the purpose of each part is described in a nutshell. The following photos and videos of instructions will show the principle of attaching each part, with the nuances of different models.

The technical complexity of any mechanism can be relatively accurately measured by the number of parts interacting in it. The effectiveness of the repair and maintenance of the tool depends on the understanding of the task of each element, but to follow a step.by.step instruction, knowledge of individual terms is quite enough. In the next, supplemented image, the list is popularly demonstrated what the chainsaw consists of, with a description of the purpose of the main parts with one short phrase (where it is required).

• The fuel tank body is the basis for installing the mechanism and control elements.
• The shock absorber plug.
• Special screw. shock absorber.
• Rubber shock absorber. 1 out of 4s installed.
• Gas trigger. an element of control of the throttle barrier of the carburetor.
• Gas thrust. a curved rod connecting a carburetor with a trigger.

• Clutch drum. the first element of contact with the chain.
• Clutch. transfers rotation to the drum with increasing speed.
• The handle of the brake of the quapi.
• Tire cover. hides clutch and oil pump (includes tension mechanism).
• Chain capture. wraps or hooks the chain when cutting.
• Starter is a mechanism of manual rotation of the crankshaft to create a spark and start engine.

The components presented above are a whole picture of the device of a standard gasoline saw. Most parts consists of several smaller parts, but they should be disassembled separately only when repairing a particular node. To get to the engine, the elements can be removed in groups without disassembling the bus lid or the starter on the screws. If you want to get a more complete idea of ​​the components of the chainsaw, or learn about all the components of a separate part, with the full version of the list.

Dismantling of the Chinese chainsaw

Detailed photo instructions for the complete and consistent separation of all parts of the mechanism. On the example of the Chinese chainsaw, the principle of interaction of all structural elements is shown. Analysis is carried out on a clean drive, without a tire, chain, gasoline and oil.

To facilitate the manipulation of the object and the convenience of access to the details, first of all we remove the handle, unscrewing the tire cover in advance.

Having released space for maneuvers, you can proceed to the main components. Remove the top cover, air filter and candle.

Unscrew the mounting screws and remove the cylinder cover.

Remove the carburetor, for which we disconnect the air damper lever, unscrew 2 fasteners and take out the base of the air filter. Disconnect gas trigger and nozzles.

We extract the lever of the throttle of the throttle so that it does not interfere with further disassembly. To do this, remove the top cover of the handle, disconnect the thrust from the trigger and take out through the hole.

Remove the starter lid, unscrewing 4 screws.

We proceed to the separation of the case with the crankcase, removing the zealor and shock absorbers.

We start disassembling the engine by extracting the ring of the carburetor knee, gasket and heat insulator. For convenience, it is better to use narrow.folds.

Unscrew the fixing nuts / screws and remove the muffler. We also take out the gasket and stilettos.

Now, the removal of the engine cylinder comes down to a simple twisting of 4 screws. You need a screwdriver or bit with a long rod.

To disconnect the piston from the crankshaft, remove the locking ring and take out the axis.

The ignition module is fixed with a pair of screws and removed for several screwdrivers of screwdrivers.

The clutch is unscrewed clockwise and rotates along with the crankshaft, which must be fixed by resting the axis on the handle of the pliers. You can use the key to corner grinding, or a hammer with a chisel, but it is better to take a special puller.

In fact, the clutch and flywheel is more convenient to unscrew until the cylinder and piston is removed, which is easier to fix, placing a segment of a thick rope or cable into the candle hole.

Following the clutch, remove the drum with an asterisk, a needle bearing and worm gear.

Unscrew the side plate of the crankcase and the lid of the oil pump, after which we remove the oil pump itself.

We pull out the pipe connecting the pump to the oil tank.

We fix the crankshaft and unscrew the flywheel (counterclockwise).

Unscrew the lid and bite off the oil seal.

It remains to unscrew all the crankcase fixation screws and disconnect the halves (effort will be required).

Extract bearings from a crankcase, you can use ordinary tapping. To install closely, the place should be warmed up by the construction hairdryer.

How to remove the tire from the chainsaw and check the driven stars

Here is how it was. I have a chainsaw, the most common. But the trouble is, she licked her studs that hold the saw canvas (I do not know how it is called scientific).

So, I found a tool repair service on the Internet, arrived, described the problem. ServiceMan says OK, the price of the question of replacing studs is 600 r. The toad of course tried to stop me from these expenses, but the saw was needed urgently. I decided to fork out.

About 15 minutes, repairs were repaired in the bowels of the workshop and finally they gave me a renovated tool. Then there is a dialogue. I am I, m.master.

I-well, yes, it’s somehow necessary to press the canvas.

I am how much. 100 p. For the nut? Ordinary nut M8??

Gave 600 p., I drove to Lerua and bought these 2 nuts for 2 r. 70 kopecks.))

4 correct ways to overheat the CPH on a chainsaw or trimmer

I work in the service center for the repair of electrical and gas tools, power equipment.Periodically, they bring to our service a jammed two.stroke gas engineering. Most often, they bring almost new. This is due to the fact that a certain percentage of buyers of the new benzo.tool do not have experience in working with this very tool, while they are not even going to read the operating manual, but immediately rush into battle. As a result-overheating of the cylinder-piston group, the transfer of metal from the surface of the piston to the surface of the cylinder, bunker and engine wedge. Of course, you can’t get anywhere from the probability of running into a production marriage, but more often the reason lies in the inexperience multiplied by inattention. I propose to get acquainted with the main reasons why you can burn your brand new chainsaw or trimmer for grass with your own hands:

one. Long work at idle. You wonder when sellers advise the client to run a new tool. No run-in a 2-tact engine does not need! Structurally, the engine cooling occurs due to the injection of the air flow with the flywheel shirt onto the engine: we squeeze the gas, the speed of the flywheel increases, we get the maximum air flow. In addition, in 2-stroke engines, an incomplete combustion of the fuel mixture occurs at idle and the engine is closed.

Shutdown of the ignition immediately after working on full gas. It is reasonable that the engine is heated to full gas to the full. And here you turn off the ignition! The engine at the peak of the temperature regime does not receive active cooling. The result can be deplorable. overheating and wedge. After working on full gas, let the engine work a little on idle, literally 10-20 seconds, and only then turn off the ignition.

The fuel mixture is used with too low oil shares, or pure gasoline or inappropriate oil. The lack of oil leads to increased friction, and therefore to greater heating of the cylinder-piston group. Use appropriate oil for 2-stroke engines, in the proportion indicated on the label and in the operating instructions.

four. Lack of proper care. The space between the cooling ribs of the cylinder and the air ducts should be cleaned in a timely manner of grass/sawdust, the presence of an air filter is mandatory. It is not allowed to enter the solid particles into the fuel system and directly into the cylinder, for example, when replacing the spark plug.

Respect yourself, your money, your tool. Read the operating manual, watch training videos and use your head.

How to choose

When choosing, it should be borne in mind that the assortment of Chinese units in the domestic market is represented by 3 main groups:

• Dear chainsaws. These are models from European manufacturers who have placed their capacities in the Middle Kingdom. They are durable, reliable, comfortable in operation.
• Average in cost mechanisms. They have less than the previous ones, the possibilities, the resource. With the right attitude, the absence of overloads can work for a long time.
• Budget motopiles. They are the cheapest, often not reliable. During overload, irresponsible attitude quickly leave the system.

All listed groups from China in the market are represented by chainsaws of different capacities, with a different set of options.

Among their diversity, the best are those that copy the models of leading motoropyle manufacturers in the world.

• on their financial capabilities;
• on the characteristics of mechanisms, their capabilities;
• on the restrictions indicated by the manufacturer;
• For consumer reviews.
• Have:
  simple for disassembly and assembly filter, clutch lid;
• A fairly stretched chain;
• oil and gas tank with sealed lids;
• guarantee.
• Work with uniform noise, without giving out ringing, bubbling.

Typology of fosions of a chainsaw

Before disassemble the chainsaw, you need to correctly determine the type of breakdown. Any malfunction in the work of the saw is conditionally related to one of two types. First. engine breakdown. Problems arise in ignition systems, fuel supply, air supply, output of spent air mixtures, cylinder-piston group.

The second type. malfunctions in other unit systems. This is a breakdown of the emergency brake, clutch couplings, guide tires, lubricant and other parts.

How to remove a star from a chainsaw

Chainsaw drive parts. key and highly loaded. The performance and performance of the entire unit depends on them. In the course of work they wear out. the chain lengthens, and the tire and teeth of the drive star are deaf. The correct choice of replacement details and accurate commissioning will allow you to extend the life of the tool and avoid increased wear and breakdowns.

Engine malfunctions

When repairing the chainsaws with your own hands, it is necessary to act as an exception. to inspect alternately all the likely prerequisites for the malfunction, starting with those, the verification and elimination of which takes the least time (about the device and operation of a two.stroke motor, see here).

Almost all types of engine malfunctions listed above may be called the ignition system failures. Therefore, when they occur, it makes sense to start searching for a malfunction from the candle. This is all the more justified that the state of the latter can give useful information about the operation of the fuel system. So, when a problem occurs, you need to turn out the candle and inspect it.

The wire is disconnected, and the candle is twisted with a special key.

If the candle is dry, this means that the problem is most likely not in the ignition system, but not admission to the fuel mixture cylinder. You can wrap the candle back and take for the fuel system. If the candle is strongly sprayed with the fuel mixture, then there is its excess. This can happen from the dilution of the carburetor or violation of the launch rules. The candle is wiped and dried, the cylinder is drained, blocked by the fuel supply and working with a starter. to exert a combustion chamber and remove excess fuel. Then set the candle in place and repeat the launch.

The presence of a large amount of black carrier also indicates malfunctions in the fuel system.

The ratio between oil and gasoline in the mixture may be disturbed, the carburetor is not adjusted or poor.quality oil is used. The candle is washed in gasoline, cleaned with a needle or an awl from the carbon, clean the electrodes with a small skin and installed in place.

In all these cases, it will not be superfluous to check the gap between the electrodes of the candle. Depending on its brand, it should be in the interval of 0.5-0.65 mm. You need to check the sealing of the candle. With its worn out or damage, the tightness of the combustion chamber may not be ensured, which leads to a decrease in compression in the cylinder and problems in the engine operation.

Even if in the case of checking the candle there is large reasons to believe that the malfunction is in the fuel system, you need to check the candle for the presence of a spark. At least in order to be sure that everything is in order with this. For this:

• put on the spark plug on the candle;
• Using pliers with insulated handles, apply a thread or a candle nut to the cylinder;
• pull the header’s handle and look. there is a spark or it is not.

In the absence of a spark, you just need to replace the candle. If the new candle does not have a spark, you need to check the condition of the high.voltage wire for the presence of a cliff and contact with the candle.

A chainsaw is a simple device that, with proper care, can last a long time. At the same time, the saw is a tool subject to various loads and, therefore, breakdowns are still found. About what caused a certain malfunction and how to eliminate it, you will learn from this article.

Carburetor check and adjustment

In service centers, carburetor adjustment is made on special equipment. For each saw, the values ​​of the rotation angles of the adjusting screws are different (they are indicated in the operating instructions). The need to adjust the carburetor does not arise very often, especially if the saw was bought from a proven seller. All our Husqvarna saws are sent to the service center before selling, where experts set up revolutions.

However, a violation of fixation of adjusting screws sometimes happens.

Causes of violation of adjustment of the carburetor of the chainsaw:

• Strong wear of the engine (piston). In this case, it is necessary to take a greater extent to fix the engine, however, the carburetor adjustment can improve the functionality of the saw for a certain amount of time.
• Blockage in the carburetor due to damage to the air filter, the use of poor quality gasoline and the formation of scale.In such a situation, in addition to adjusting the carburetor, it will also be needed to flush.
• Strong vibration of saw or damage to the protective cover. This is extremely rare, but there are still cases.

Signs that indicate the need to adjust the carburetor of the chainsaw:

• The engine either does not start, or starts up and immediately stalls. This is due to the use of poor fuel mixture.
• A significant increase in fuel consumption and an increase in exhaust volume. the amount of exhaust gases suggests that the fuel does not completely burn out. The reason for this can be oversatuity of the fuel.

The carburetor adjustment scheme for different models of the chainsaws is different and described in the operating instructions. However, the general principle remains the same: it is necessary to change the quantity and quality of the fuel mixture supplied to the engine cylinder.

Three screws will help us to adjust the carburetor:

• “L”. LOW, to configure low speeds
• “H”. High, to configure the upper revolutions
• “T” (“LA”, “S”). to configure the idle stroke (the models that have only one screw have exactly the “T” screw)

When adjusting the carburetor of the chainsaw, the following rules should be followed:

• Make sure that the cutting chain of saws is directed in the opposite side of you
• Put the saw on a stable even surface, the cutting part should not touch any objects.

Please note: the instructions indicate the exact angles of rotation of the adjusting screws. Accurate compliance with the instructions of the instructions will avoid engine damage.

The process of adjusting the carburetor itself includes two points: basic (with a non.working engine) and final (with a heated engine).

Uneven sharpening

According to the instructions for sharpening circuits, grinding teeth is supposed to be the same distance, and in the independence on which side they are located. Observing this simple requirement, you can protect yourself from the problems associated with the fact that the chainsaw is led away by sawing.

Unevenly stubborn teeth are the most common problem of crooked saw.

Having tightened the chain with a file, it is not always possible to control the length of the tooth using the technique of counting the number of movements with a file.

This is due to the fact that the wear of the teeth is uneven, some are more damaged and a larger number of movements are required by the file, in order to bring them to normal, which means the size of such teeth will decrease significantly, compared to the rest.

How to avoid improper sharpening

In order to warn the cut curve due to uneven sharpening, it is possible from time to time or with severe damage to use a special sharpening machine for editing the chain. Buy a machine and sharpen yourself or give for sharpening to the workshop.

The fact is that the machine during sharpening is configured on the most worn tooth, which has a smaller size among all. After the sharpening is carried out, all the teeth will have the same size, which will be equal to the tooth, through which tuning was made.

The disadvantage of this method is that the resource of the chain is significantly reduced, t. to. you have to grind hard even damaged teeth. Try to use the chainsaw, monitor the nails and any other metal products that may come across when cutting old boards and other trash.

How to determine the wear of the chainsaw tire

The tire of the chainsaw is a guide and fixing element of the saw headset. The canvas itself, the leading star and fasteners are consumables.

It is very dangerous to work with a failed tire, since at large speeds it can break off the case and damage the operator, or due to poor fixation on such a canvas, the chain may jump off and injure.

Most often the wear of this element of the chainsaw occurs naturally, due to long.term operation. Since it accounts for the main load in the implementation of the saw. But there are situations when the tire breaks due to improper work with the tool. Excessive load that does not correspond to the technical characteristics of the tool.
