How to assemble a spring chainsaw spring

As soon as you diagnosed the cause of the chainsaw breakdown, you found the damaged part of the starter, which could not cope with the intensive and dynamic load, you can start repairing.

REPAIR OF TRASIC

If the cable burst, then the teeth of the ratchet (not necessarily all) will be crushed. This slows down the speed of rotation of the crankshaft. But why the cable bursts? Do not forget about his friction, about the body of the starter system, over time, this leads to damage to the cable.

  • We disassemble the case, that is, remove the lid;
  • We gently raise the rattle of the ratchet system, make sure that the return spring does not jump off the nest (ask someone to help you, the assistant will hold the spring until you change the cable);
  • We fix a new cable inside the handle, do not forget to wind it on a roller located in drum grooves;
  • We collect the case.

Spring repair

Not all manufacturers make a high-quality steel spring, but even if it is highly classy, ​​over time it has to be replaced or repair due to damage to the spring and drum junction. A loop is formed in this place.

If the junction of the drums and the spring is damaged, it is not necessary to replace the spring. Just:

  • Pass the damage site (remove dust, dirt, traces of oil);
  • We heat the spring (up to about 650C so that it becomes raspberry);
  • Cool gradually;
  • We wrap at about 150 degrees Celsius (we FOCUS on the restrictive ledge next to the inside of the drum, wrapping the end of the spring exactly in the form of a limiter).
  • We insert the spring in its place.

Worry about the elasticity of the spring will not be worth.

But what to do if you needed a replacement of the spring (if this part was damaged)?

Then we change the old one to a new one, focusing on the algorithm of actions:

  • We extract the mechanism (dismantle the clip), make sure that no detail is injured at this stage;
  • We examine the inside of the mechanism where a spring is located, repeating the shape of a C-shaped functional element;
  • Remove the spring, fixing its top with your fingers, slightly removing the handle of the starter system;
  • As soon as you took out a damaged spring, we install a new one, wound it according to the old example, avoiding twisting and bending the material (we act slowly so that in the future there are no problems with unwinding this part).

If you managed to disassemble the starter and remove the spring, you will quickly understand how to assemble a chainsaw starter at an intuitive level. The main thing is to reliably fix the clip of the mechanism.

As soon as you finish collecting the starter and make sure that all the fasteners are in place, tightly screwed, try to start the unit.

Important! After such repair during the first operation, sometimes the chainsaw is started after 10-20 cable jerks. Do not panic! This is normal, since the spring needs every jerk so that it becomes completely

As you can see, having dealt with the structural features of the starter system, the types of breakdowns and their causes, you can independently carry out the repair of the details of this functional node, their replacement, without resorting to the services of masters of service centers. They would have to pay decent money for the work that you can handle yourself.

Device and principle of operation of the starter of the chainsaw

All types of chainsaws, both Chinese and European production, are equipped with starters of the identical design and the principle of action. The universal design of the starters allows you to use these devices on both brand chainsaws and on semi.Official tools supplied from the Celestial Empire. It is only important to note that some distinguishing features are have instruments of domestic production.

A starter for a chainsaw is a simple mechanism consisting of:

The principle of operation of such a device is also quite simple. When stretching the handle, which is connected by means of a cable with the drum of the ratchet, its movement occurs. The drum when moving is included in the hook with slots of another drum, which is located on the shaft. Thus, manually moves the cut of the saw, which makes several revolutions. As soon as the handle returns to its original position, which is facilitated by the return spring, the slotted connection is lost, which leads to the stop of the shaft. With each movement of the crankshaft in the cylinder, the amount of fuel-air mixture increases, which ultimately contributes to its ignition.

The greater the power of the tool, the more jerks should be made by the starter to start the motor. The return spring is responsible for accelerating the return of the drum to its original position, the manufacture of which is carried out using steel with a high degree of elasticity.

Over time, with the constant operation of the tool, problems are observed with the launch of the engine, or rather, with the functioning of the starter. If such problems arise, then the starter can always be repaired. If the principle and device of the starter is known, then it will not be difficult to repair it with your own hands.

Typical breakdowns and repair of the chainsaw starter

Before carrying out repairs, it is necessary to find out the reasons for the breakdown. Since the product is constantly subjected to dynamic and other types of loads, its failure is not excluded. Frequent causes of starter breakdowns are: rupture of the cable, abrasion or painting several shits of the rattle drum, damage to the spring, a crack of the pulley and others. To determine why the saw does not start, you will need to conduct an appropriate revision of the starting mechanism. Consider the main types of malfunctions, and also find out how to properly repair the product.

Replacement of the cord

The starter cord is a strong rope, which is strong enough to wear, but even its technical properties do not save it from damage. The rope, at each start of the tool, rubs against the starter cover case, which leads to gradual overwhelming and wear.

If the cord is grinding, then to replace it, you need to disassemble the case of this node. After removing the cover, it is necessary to raise the drum, but only so that it does not jump out of his seats. It is recommended to carry out such work together with a partner who will fix the spring, and you will do the replacement of the cable. The remnants of the old cable should be removed, then fixed the new product in the handle and in the frame of the drum. After that, the cable should be wound on the roller, and at the end, assemble the case.

How to replace the chainsaw starter spring

If damage to the spring is observed, which is often on Chinese instruments, then the mechanism can only be repaired by replacing it. But if its damage occurred at the place of connection, that is, the ear burst, then it can be repaired.

The repair of the spring is a heating of the destruction site up to 600 degrees, after which it is slow to cool it up to 100 degrees, in which the end is wrapped in the shape of a fragment. Thus, it will be possible to avoid loss of elasticity of the product, which will extend its service life. Although most experts simply carry out the replacement of the product with a new.

The process of replacing the spring is carried out in the following sequence:

  • The clip or drum of the mechanism is originally extracted.
  • A spring is located inside the drum. To dismantle it, you will need to fix its upper part, and then pull the starter handle aside.
  • When the old spring is extracted, you need to install a new. In this case, it is imperative to clean the body.
  • When installing a new spring, you should insert it into the starter, and then get into the groove to the groove.
  • At the end of the work, you can put on the drum and install the starter cover in place.

The detailed process of replacing the spring is considered in the video:

Replacing dogs of a flywheel

If you need to replace the dogs or the answer of the flywheel, then it is also not difficult to do it. This will need to dismantle the flywheel, and then remove the dogs. You should install new dogs exclusively those that were initially (plastic or metal). This is very important, since replacing plastic dogs with metal ones will lead to an accelerated wear of the flywheel. Details of replacing dogs of the starter of the chainsaw are considered in the video below.

In conclusion, it is important to note that to repair the starter of the chainsaw, you do not need to have special skills or experience. All work can be performed independently if you treat the repair process with all responsibility. Timely conduct of the prophylactic work of the chainsaws will avoid the occurrence of breakdowns when performing work in the field.

Starter is one of the most important mechanisms in the device of any modern chainsaw. The launch of the tool engine under any weather conditions depends on it. The starter for the chainsaw is released by a simple design, it is easy to serve and repair it with your own hands. However, in order to eliminate the breakdown, you must first find its cause. For this, most often it is necessary to completely disassemble the standard mechanism.

Repair of the starter of the chainsaw

With frequent launches of the chainsaws, some starter details are constantly subjected to dynamic loads. As a result, a cable may burst, several teeth of the ratchet chill, and the shaft will turn out at a much lower speed. Therefore, the audit and even the repair of the starter. Operations, sometimes carried out several times per season.

Replacement of the cord

When it is pulled, there is a constant friction of the cable about the starter case. For replacement, disassemble the hull of the node, and carefully lift the rattles in such a way as not to allow jumping from their nests of the return spring. It is better to do such work together: the assistant fixes the spring, while the cable is replaced. After fixing the cable in the handle and in the grooves of the drum, the cable is wound on the roller, and the case is assembled.

Spring repair

If the material of the starter spring is poor.Quality, the spring bursts (usually at the place of its connection to the drum, where it forms a loop). Replace the spring in this case is not worth. Carefully clean its surface from dirt and traces of lubrication, gently polish the destruction place, and then release the spring at 600 650 ° C (the spring steel should purchase raspberry color). It is necessary to cool the spring slowly, and at 100 150ºС you can already carefully wrap its end in the shape of a restrictive protrusion on the inner surface of the drum (steel will acquire the necessary plasticity) and insert into place. The elastic properties of the spring will not change.

How to put a spring on a chainsaw starter?

Placing a starter spring in the desired groove is not easy to do with an experienced user. First, the spring should be twisted to the previous diameter and installed in the cavity of the hub of the drum. The outer end of the spring is fixed for the restrictive ledge, and the external using the screwdriver should be placed opposite the holes in the lock. The loop at the inner end of the spring with a screwdriver is combined with the hole, after which the disk is lowered. The disk is checked whether the dog of the ratchet has become in place. Next is the assembly of the ratchet itself.

After installing the spring, it is necessary to adjust its tension. To do this, a cable is inserted into the groove on a circle, and a return spring is twisted around it. After eliminating the slack, it is better to wind the spring at an additional several revolutions to guarantee the required part of the part.

Spring repair

The procedure for repairing the start of the launch system:

  • Remove starter From the tool of the tool.
  • Remove the protective cover.
  • Wrap the cable from the end of the pulley so that the mechanism does not roll.
  • Insert the other end of the cord into the hole in the protective cover.
  • Tighten the cord by 17-20 cm to check the rotation of the pulley of the spring mechanism.
  • Check the service of the spring after the removal and release of the mechanism.
  • Unscrew the pulley from the side of the generator, twisting 3 fasteners.
  • Remove the pulley and cord.
  • Check the condition of the parts for wear, damage and breakdowns. If the spring gaps are small, the defect can be eliminated by welding.

How to put a spring

To install a new spring, the following actions must be performed:

  • Carefully remove the mechanism clip.
  • Contains a spring mechanism near the C-shaped element.
  • The trigger and the tension mechanism of the upper part of the spring.
  • Remove the worn.Out mechanism and the new spring wind. Bends and bends should be avoided.
  • Collect a new spring mechanism. It is recommended to do this slowly so that the mechanism does not spin.
  • Fill the spring and insert it into the starter mechanism.
  • Write down the clip thoroughly.

Replacement of the starter

  • Remove the tool case assembly.
  • Unscrew the fasteners and remove the side cover.
  • Unscrew the fastener screw that is attached to the starter.
  • Remove the trigger and spring mechanism.
  • Remove the pulley with a cord.
  • Replace all worn out and damaged objects.
  • The winding of the pulley.
  • Install a new starter.
  • Replace the pulley with a cable, clip and spring.
  • Screw the side cover and install the node on the chainsaw housing.

It is recommended to inspect it for defects, check the build quality and the presence of a guide sleeve.

Starter is the most modern chainsaws. Run the tool engine under any weather conditions. A starter for a chainsaw is characterized by a simple design, it is easy to serve and repair it with your own hands. However, to correct the error, you must first find its cause. To do this, you often need to completely disassemble the standard mechanism.

The device of the chainsaw starter

Usually, chainsaw The starter consists of several parts.

The protective cover is installed on top of all the elements of the starter. The initial principle of action is almost the same. There is a pen that holds the cable in the special groove of the chainsaw housing. A sharp raising of the handle means the last. At this moment, the engine is launched on the engine shaft.

When fuel is removed from gasoline, rotation occurs, which leads to compression of the existing fuel mixture located between the main cylinder and the standard piston at this time.

As the volume of the cylinders increases, the amount of fuel mixture consumed, which is necessary for its ignition in the future. Accordingly, the operator of a powerful saw needs more energy than the owners of household tools. Fifth power supply manufacturers use return springs.

How to put a spring on a starter chainsaw?

The installation of the spring in the corresponding groove is a rather difficult task. First of all, twist the details. After that, it must be inserted into the cavity of the usual hub of the drum. To fill the spring in the chainsaw starter, act as follows:

  • The outer end of the spring used should be recorded in a special limited ledge. The other end is installed using a screwdriver in front of a conventional hole inside the lock;
  • Next, the loop, located on the inside of the end of the standard spring, should be leveled with holes. It is better to use a screwdriver. When aligning the ends, the disk will be lowered;
  • After installing the disk, make sure that the chainsaw is in place. Then you can assemble the ratchet in the reverse order.

To wind the spring on starter chainsaws must have all holes and recesses. After installing, tighten the spring. As soon as the weak side is removed, the springs will be wound at several revolutions.

How to assemble starter On a chainsaw?

After replacing the faulty elements of the starter, it was time to collect it. This can lead to a trigger malfunction. The assembly of the node should be performed in the following sequence:

  • For a standard cable, you need to insert the thread into the factory hole of the coil. However, the cord should not be wound;
  • Next, you need to insert the coil into its base place. At this moment, many newcomers make a common mistake. There are 2 slots on the surface of the coil. Spiral springs. This requires it to be firmly in its original place. The correct installation should be checked by turning the coil clockwise until the resistance appears;
  • Then you need to install a light chainsaw. Coils are installed;
  • After this, a screw and a washer are required to fix the device;
  • Further, the other end of the cord should be braided into a special outlet;
  • The next step is the installation of the cable in the starting handle. A medium.Sized knot. If he is too small, he quickly wraps up on a shock drum;
  • Then release the loop on the header’s head. Immediately after that, start turning the trigger clockwise. In this case, the cord does not need to be wrapped. Then you need to fix the coil with your hand and pull the loop by the handle;
  • Then you need to check the work of the trigger;
  • If the knot works correctly, it remains to install it on the tool.

Starter For a chainsaw. We learn independent repairs

For brisk starting at least any chainsaw is required starter. With accelerated scrolling of the crankshaft, the tool is compressed by the fuel-air mixture supplied to the engine and its subsequent ignition. Therefore, the normal work of the starter for the chainsaw determines the performance of the entire mechanism.

Replacing the launch of the STIHL chain rosopie

STIHL chain saw. This is a tool designed for harvesting wood, plant processing, landscape design and other household needs. If any details are faulty or the device is faulty, you need to repair the STIHL chainsaw.

The main malfunctions

The chainsaw should be used in accordance with the operating instructions, then it will last a long time and will not fail. All possible malfunctions of the STIHL chainsaw can be identified and corrected independently. Let’s look at the main problems that can arise in the components and design of the device, and how to repair the STIHL 180 chainsaw with your own hands.

Fills the candle

If you notice that the candle is pouring on the STIHL chainsaw, perhaps the fuel system is faulty. The engine should work on a mixture of gasoline and oil. If the mixture is poor, the power is reduced, the cylinder overheats, and the saw systems wear out. Wet spark plug on the STIHL chainsaw is caused by a disproportion in the fuel mixture. The lack of air in the mixture prevents the proper combustion of the emulsion.

Using low.Grade gasoline can lead to engine wear.

Blurring the spark also causes the use of oil for 4 strokes and wear of the piston. If this malfunction occurs, remove the gas tank cover and adjust the fuel supply. The air intake should be in good working condition. The clogged filter should be blown, but it is better to replace it. How to clean filters, described in the instructions for a chainsaw.

How to replace the chainsaw starter spring?

In order to replace the old spring in a disassembled starter, you must act in the following order:

Before installing the spring of the chainsaw, you will need to extract the clip of the mechanism. This should be done extremely carefully so as not to break the part; Then you need to look inside the clip-in it you will see a spring wrapped around the C-shaped element. To pull out the spring, fix its upper part with your finger and slightly pull the starter handle to the side; After extracting the old spring, it is necessary to wind a new part

At the same time, try to avoid overcurrents and twisting a new spring element; To assemble the spring of the chainsaw starter, you need to act as carefully as possible, otherwise one wrong movement can lead to unwinding the spare part; After you managed to completely insert the spring into the starter, you must carefully fix the clip.

At the last stage, it remains only to assemble the starter of the chainsaw and try to start the tool. It is possible that you will have to do from 10 to 20 jerks. This is necessary so that the spring finally rises in its place.

How to repair a starter of a benzo.Tool with your own hands?

In the case of a break in the starter cord, everything is clear: we take out the old rope, take the suitable one along the length and thickness (you can linen), stretch it through the hole in the coil, tie the knot. Next, we take the spring to the number we need, only after which we fix the handle. And the voila! About how all this is done is clearly shown below.

Installing or replacing the starter of the starter motorcycle, motorcycle, trimmer

But what to do if everything is in order with the rope, and the coil (pulley) of the starter is not wound? Consider this issue step by the example of the starter of the ADA Grounddrill gasoline motorized car, having a pulley with two metal antennae for 2 hooks.

In the case of other types of manual starters of the similar structure, which are widely used in gasoline motorcycles, trimmers and motorized carriers, the entire starter repair process will look similar, differing only in some nuances.

Starter repair: disassembly

Unscrew the screw with which the pulley is attached to the starter cover. We take out the antennae, spring. We pull the pulley itself carefully so that the spring does not bounce into the face. Even with the most neat disassembly, it usually immediately flies out of the coil and sharply turns into a long metal strip or twisted by rings.

Gently pull out the white.Tolerator’s white coil. Do not be wounded up by the spring!

If the spring burst or one of its hooks-stalks has broken, then it will not work out to repair the starter and quickly-it is necessary to replace the spring. In order not to spend money on the purchase of a new starter, you can look for only her on sale.

In case the starter spring simply fell off, t. E. One of the hooks came out of the hook, it is enough to insert it, if necessary, slightly tightening the hooks more tightly (just do not break off!) Install the spring with an external hook in the groove of the pulley and begin to twist it, while holding your fingers inside the coil and preventing it from jumping out of there.

Clutching the spring to the pulley, roll the spring in circular motion

The first time Insert the starter spring It may not seem so simple, but everything comes with experience. Having trained a little, you can easily wrap the spring into the pulley in a maximum of a minute.

The winding of the starter spring is made. It remains only to assemble the starter and take the spring to the desired value

How to assemble a starter?

The most important thing in the process of independent repair of the starter is to collect it correctly.

After the spring is completely wound, you need to carefully turn the coil and insert into the starter case so that the second spring hook enters the groove of the case.

Repairing the starter on the trimmer (replacing the ratchet)

By installing the pulley (in this photo. Black), look through the hole in it so that the spring hook gets into the groove on the starter cover

Then, if there is a spring under the screw, we install it first, not forgetting to put the washers from below and from above the spring.

Gently insert a cup with antennae into the grooves of the coil and tighten the screw.

Then keep sure that the puck is on the sprout does not fall. Why is it important? The fact is that the spring scratches a plastic cup with its end, as a result of which the latter wear out and begins to tightly pressed with a screw to the reel. For this reason, a situation may arise, very similar to the breakdown of the spring: the handle stretches out of the starter, but does not return back. However, when the starter is weakened, this problem disappears. It is easy to eliminate such a starter malfunction: it is enough to choose a spring of the same diameter, but a little longer, or put an additional washer. If we simply slightly tighten the screw, then it will be twisted and fly out, and this will increase the likelihood of a spring breakdown, since the pulley will not fit tightly with the starter case.

The coil to the body was screwed, now we need to pull the spring. Before this, it is necessary to remove the starter’s handle from the rope in advance. If the knot is too durable, then you can just cut it or try to untie it, for example, using a pair of pliers. This is done so that after you bring the spring, you can pass the rope into the opening of the starter cover. The second end of the rope should be fixed in the coil even before it is installed in the case, it is not required to be roped on the pulley before pulling the spring. You will do it after.

Before taking a spring, estimate how much the reel revolutions should be wrapped in a rope. Suppose the length of the rope at the starter of the Motor ADA Grounddrill-5 corresponds to 5.5 revolutions around the coil. In this case, we make at least 6 revolutions of the coil in the direction opposite to the direction of wiring.

So, let’s get down. Without wrapping, insert the rope into a groove specially designed for it in a coil. Everything is ready, proceed to pulling the spring. To do this, we rotate the coil counterclockwise. In the direction opposite the direction of rotation of the coil when watching the rope. It is more convenient to do this not on the knee, but pressing the starter with one hand to the floor, and the second turning the coil right behind the rope mounted in it. If the experience is not enough, then you can rotate with both hands directly the pulley itself, but the rope will interfere with it, which can create additional inconvenience. After the required number of revolutions is made, we spread the end of the rope through the hole in the starter cover, put on the handle, fix it with a knot. It is more convenient to do this together with a partner, so that the end of the cable does not hit the end of the starter by chance.

By the way, on your own, you can introduce some refinement to the design of the starter in order to more reliably fix the end of the spring inside the coil. There is enough fantasy here. Now I will explain what it happens for. It often happens that the spring in starters of this type after the first such independent repair and installation of the starter on the unit flies after a few jerks again. There is no hook in the groove of the coil. And this despite the fact that the coil is almost tightly adjacent to the starter cover and the spring there, well, should not even hang up and down freely, and even more so until the spring out of the gear. It turns out that when the cable is jerking, it pulls the spring, pulls out of the groove. In this case, you can make the following: cut a narrow strip of metal, which in thickness could squeeze closely into the groove of the coil with the hook itself. So the hook will not hang free in the groove, which means that it will not be so easy to break out.

For the quick launch of any chainsaw, a starter is required. With accelerated scrolling of the crankshaft, the tool is compressed by the fuel-air mixture supplied to the engine and its subsequent ignition. Therefore, the normal work of the starter for the chainsaw determines the performance of the entire mechanism.

Almost all leading manufacturers of chainsaws complete their products with starters of a similar principle of action. It is no coincidence that specialized stores offer universal designs of starters, which are equally successfully suitable for both the chainsaws, Khuskvarna, Makita, and for Chinese semi.Official fakes under the named brands. Only starters of domestic production (forester, Urals and a number of others) have some features only.

The principle of operation of the starter for the chainsaw is as follows. A handle is installed in the groove of the case, through which the cable is missed. If the handle is sharply lifted, the cable is stretched, and introduces the drum of a ratchet that transfers the movement to the drum with the slots provided for the shaft. In this case, the crankshaft makes several revolutions, and the working mixture in the space between the piston and the cylinder head is compressed. Accordingly, when lowering the handle, the contact between the ratchet and the slots is lost, and the shaft stops.

With an increase in the volume of the engine, the required amount of fuel-air mixture required for its subsequent ignition is also growing, so the number of jerks for the starting cable for large power saws increases. Therefore, in order to accelerate the return of the drum, baked return springs made of steels with high elastic properties are used.

The relief of the launch of the chainsaw is realized in the following ways:

  • Preliminary enrichment of the working mixture, for which there is a special damper in the design of the carburetor.
  • By installing an automatic decompression valve, which provides a decrease in the working pressure in the chainsaw cylinder.
  • By installing an additional spring, which during the movement of the cable facilitates the spinning of the crankshaft.
  • The presence in the design of some chainsaws (for example, Partner S, Maxcut, etc.) the primer. The pump that provides preliminary pumping of the fuel.

Starter of a chainsaw: DIY repair

An indispensable tool for sawing firewood and rolling of trees is a chainsaw. Following the recommendations of the manufacturer and the implementation of the necessary preventive measures will ensure a long “life” of the unit. But even at the most reliable mechanism over time, problems arise, most of which can be eliminated with your own hands without the help of specialized centers. One of these malfunctions can be a chainsaw starter, the repair of which can be carried out independently, subject to a certain sequence of operations.

Almost all leading manufacturers of chainsaws complete their products with starters of a similar principle of action.

Therefore, the normal work of the starter for the chainsaw determines the performance of the entire mechanism.

Almost all leading manufacturers of chainsaws complete their products with starters of a similar principle of action. It is no coincidence that specialized stores offer universal designs of starters, which are equally successfully suitable for both the chainsaws, Khuskvarna, Makita, and for Chinese semi.Official fakes under the named brands. Only starters of domestic production (forester, Urals and a number of others) have some features only.

The principle of operation of the starter for the chainsaw is as follows. A handle is installed in the groove of the case, through which the cable is missed. If the handle is sharply lifted, the cable is stretched, and introduces the drum of a ratchet that transfers the movement to the drum with the slots provided for the shaft. In this case, the crankshaft makes several revolutions, and the working mixture in the space between the piston and the cylinder head is compressed. Accordingly, when lowering the handle, the contact between the ratchet and the slots is lost, and the shaft stops.

With an increase in the volume of the engine, the required amount of fuel-air mixture required for its subsequent ignition is also growing, so the number of jerks for the starting cable for large power saws increases. Therefore, in order to accelerate the return of the drum, baked return springs made of steels with high elastic properties are used.

The relief of the launch of the chainsaw is realized in the following ways:

  • Preliminary enrichment of the working mixture, for which there is a special damper in the design of the carburetor.
  • By installing an automatic decompression valve, which provides a decrease in the working pressure in the chainsaw cylinder.
  • By installing an additional spring, which during the movement of the cable facilitates the spinning of the crankshaft.
  • The presence in the design of some chainsaws (for example, Partner S, Maxcut, etc.) the primer. The pump that provides preliminary pumping of the fuel.

With frequent launches of the chainsaws, some starter details are constantly subjected to dynamic loads. As a result, a cable may burst, several teeth of the ratchet chill, and the shaft will turn out at a much lower speed. Therefore, the audit and even the repair of the starter. Operations, sometimes carried out several times per season.

When it is pulled, there is a constant friction of the cable about the starter case. For replacement, disassemble the hull of the node, and carefully lift the rattles in such a way as not to allow jumping from their nests of the return spring. It is better to do such work together: the assistant fixes the spring, while the cable is replaced. After fixing the cable in the handle and in the grooves of the drum, the cable is wound on the roller, and the case is assembled.

If the material of the starter spring is poor.Quality, the spring bursts (usually at the place of its connection to the drum, where it forms a loop). Replace the spring in this case is not worth. Carefully clean its surface from dirt and traces of lubrication, gently polish the destruction place, and then release the spring at 600 650 ° C (the spring steel should purchase raspberry color). It is necessary to cool the spring slowly, and at 100 150ºС you can already carefully wrap its end in the shape of a restrictive protrusion on the inner surface of the drum (steel will acquire the necessary plasticity) and insert into place. The elastic properties of the spring will not change.

Placing a starter spring in the desired groove is not easy to do with an experienced user. First, the spring should be twisted to the previous diameter and installed in the cavity of the hub of the drum. The outer end of the spring is fixed for the restrictive ledge, and the external using the screwdriver should be placed opposite the holes in the lock. The loop at the inner end of the spring with a screwdriver is combined with the hole, after which the disk is lowered. The disk is checked whether the dog of the ratchet has become in place. Next is the assembly of the ratchet itself.

After installing the spring, it is necessary to adjust its tension. To do this, a cable is inserted into the groove on a circle, and a return spring is twisted around it. After eliminating the slack, it is better to wind the spring at an additional several revolutions to guarantee the required part of the part.

It is not recommended to carry out the repair of the ratchet mechanism itself at home, since many operations will require the use of CNC machine. It’s easier to purchase a new node in specialized stores.

Today we will consider problems with malfunctions of the starter of the chainsaw And we will eliminate them. This type of breakdown is not rare with intensive operation of a gasoline saw. And in our case, in logging, this happens systematically.

How to replace the chainsaw starter spring?

In order to replace the old spring in a disassembled starter, you must act in the following order:

  • Before installing the spring of the chainsaw, you will need to extract the clip of the mechanism. This should be done extremely carefully so as not to break the part;
  • Then you need to look inside the clip-in it you will see a spring wrapped around the C-shaped element. To pull out the spring, fix its upper part with your finger and slightly pull the starter handle to the side;
  • After extracting the old spring, it is necessary to wind a new part. At the same time, try to avoid overcurrents and twisting a new spring element;
  • To assemble the spring of the chainsaw starter, you need to act as carefully as possible, otherwise one wrong movement can lead to unwinding the spare part;
  • After you managed to completely insert the spring into the starter, you must carefully fix the clip.

At the last stage, it remains only to assemble the starter of the chainsaw and try to start the tool. It is possible that you will have to do from 10 to 20 jerks. This is necessary so that the spring finally rises in its place.

How to assemble a spring chainsaw spring

For brisk starting at least some chainsaw you need a starter. With accelerated scrolling crankshaft the tool is compressed by the fuel-air consistency submitted to the engine and its next ignition. Therefore, the usual work of the starter for the chainsaw determines the performance of the entire mechanism.

In fact, all leading chainsaw manufacturers complete their products with starters of a similar principle of act. It is no coincidence that specialized stores offer universal designs of starters, which are idyntually suitable for both the rupernation of calm, Khuskvarna, Makita, and for Chinese semi.Official fakes for the named brands. Some features are owned only by starters of Russian.Made chainsaws (forester, Urals and a number of others).

The principle of operation of the starter for the chainsaw is as follows. A handle is installed in the groove of the case, through which the cable is missed. If the handle is sharply lifted, the cable is stretched, and introduces the drum of a ratchet that transfers the movement to the drum with the slots provided for the shaft. With all this, the crankshaft makes several revolutions, and the working mixture in the space between the piston and the cylinder head is compressed. Accordingly, when lowering the handle, contact between the ratchet and slots disappears, and the shaft stops.

Spring repair

If the material of the starter spring is poor.Quality, the spring bursts (usually at the place of its connection to the drum, where it forms a loop). Replace the spring in this case is not worth. Carefully clean its surface from dirt and traces of lubrication, gently polish the destruction place, and then release the spring at 600 650 ° C (the spring steel should purchase raspberry color). It is necessary to cool the spring slowly, and at 100 150ºС you can already carefully wrap its end in the shape of a restrictive protrusion on the inner surface of the drum (steel will acquire the necessary plasticity) and insert into place. The elastic properties of the spring will not change.

How to put a spring on a chainsaw starter?

Place the spring in the appropriate groove is a rather difficult task. First of all, the detail will need to be twisted, returning it to the previous size. After that, it needs to be inserted into the cavity of the standard hub of the drum. To tie the spring into the starter of the chainsaw, you need to act in this order:

  • The outer end of the spring used must be fixed in a special restrictive ledge. In this case, the second end using the screwdriver will need to be installed opposite the standard hole inside the lock;
  • Further, the loop located on the inner end of the standard spring should be combined with the hole. To do this, it is better to use a screwdriver. At the ends of the ends, the disk will need to be lowered;
  • After installation of the disk, you need to check that the dog of the factory ribbon mechanism of the chainsaw stands in its regular place. Then you can collect a ratchet in the reverse order.

To wind the spring on the starter of the chainsaw, you need to take into account all the available holes and recesses. After installation, you need to pull the spring. As soon as the weakness is eliminated, the spring will remain at several revolutions. This is necessary to support the required tension of the installed part.

The procedure for the repair

Step 1. First we unscrew the screws of fastening the starter cover (usually 3 or 4). When buying a chainsaw, a candle key with a simple screwdriver is attached to it. If there is no branded box at hand, you can use ordinary tools. Next, remove the starter from the chainsaw body. As a rule, there are no problems with this even with sufficient dusting and clogging of the tool.

Step 2. Then you should unscrew the screw of the supply mechanism of the smooth start and coil. In this case, you need not to lose the puck that is necessary for the design. Immediately after we extract a smooth start mechanism and a winding reel on which traces of damage may be present (for example, fasteners).

Step 3. Prepare a new cord 120 or 130 cm long. If you did not work out the original cable, the nylon household rope is also suitable, from which it is necessary to melt the ends by firing with a match.

Step 4. We tie the knot at one end, which, when fixed on the coil, should not protrude outward, and season the cord. Next, insert the coil into place so that the hook of the spiral spring gets into the slot. Turn it clockwise and check the correctness of the installation.

Step 5. Install a smooth start mechanism on the case and fix it with a screw with a puck. Then we refuel the second end of the cord into the exhaust hole.

Step 6. We spread the rope in the launch handle and tie the knot at its end. We release the chainsaw starter and twist without wrapping the cord. Then we fix the coil with your hand, pull the loop by the handle out. Holding the cord and the mechanism with the hand, we ensure the winding of the cable to the reel.

Step 7. Check the serviceability of the starter mechanism after replacing the cable and fix the node to the chainsaw housing with fasteners.

If repairs using a linen rope are not an option, managers of the PPD Tool store will select a branded starter cord from an extensive assortment of spare parts for chainsaws.

How to fix a starter on a chainsaw

The reason for the malfunction of the launch system of the chainsaw may be:

  • Drive pulley. This part is subjected to high axial and radial loads, therefore, before starting work, it is recommended to inspect the pulley for damage and cracks on the back of the case. If necessary, repair the part or replace it with a new.
  • Spring mechanism. If he has lost his properties or there are cracks or breakthroughs on it, it is necessary to replace this element. It is also recommended to inspect the places for the presence of defects.
  • The rope of the launch system. The rope should be examined for wear and injuries. If necessary, replace the part and install it with the pulley.

Diagnostics

Diagnosis of the tool launch system is carried out as follows:

  • Unscrew the fasteners and remove the lid.
  • Turn a screw that attaches the mechanism to the protective cover.
  • The starter smoothly launch, removing the spring and clamps from it.
  • For examination for wear and defects, a reel with a cable is dismantled.
  • Check the fuel system for water in it. If there is water inside the system, then the fuel fluid must be replaced.
  • Conduct an inspection of the power unit for overflow with fuel fluid. In this case, you need to unscrew and dry the spark plug, pull the starter, dismantling the air damper.
  • Check the spark of spark.

Replacement of the cord

In order to replace the cord, the following tools will be required:

Replacing the launch cord is as follows:

  • You need to unscrew the fasteners that hold the side cover with a screwdriver.
  • Then dismantle the starter from the tool body.
  • After that, you need to turn the lid and conduct an inspection.
  • Then dismantle the clip and spring.
  • Untie the knot on the rope.
  • You need to pull out the pulley on which the cord is wound. Remove the cord and replace it with a new.
  • Then get the pulley in place and tie the rope on the knot. Set the clip and spring.
  • After that, tighten the lid using fasteners.
  • At the end, install the starter in place and fasten the fasteners.

Spring repair

The procedure for repairing the start of the launch system:

  • Dismantle the starter from the tool.
  • Remove the protective cover.
  • Wind the cord from the end of the pulley to avoid scrolling the mechanism.
  • Pass the second end of the cord in the hole of the protective cover.
  • Pull the cord 17-20 cm to check the turn of the pulley of the spring mechanism.
  • Check the operation of the spring after stretching and releasing the mechanism.
  • Unscrew the circle circle from the side of the generator, removing 3 fasteners.
  • Demolish the pulley and cord.
  • Check the condition of the parts for wear and the presence of damage and cliffs. If the cliff is small, then you can eliminate the defect by welding.
