How to remove a fishing boar from a trimmer

Fishing lines is called consumable, which consists of nylon, and serves as a cutting device. Through this equipment, the grass grows, which is ensured due to rotation of the instrument head with a high frequency. This material has a different thickness, which depends on its use on the corresponding tools of low-power (from 1 to 1.6 mm), electric from 500 W (2-2.4 mm) and gasoline trimmers with motorcycles (from 2.4 to 3. 2 mm).

The more powerful the tool, the accordingly there should be a cutting equipment. This affects not only the quality of the injection of grass, but also on the life of the material. If you ask the question of how to wind a trimmer coil, then it’s time to change the reload of the tool. With the onset of spring, this issue is becoming more and more in demand, so it’s time to understand the step.By.Step instructions for replacing the trimmer line in the coil of the trimmer.

Trimmer coil with one osmus

Many owners and experts note the simplicity of the operation and refueling of bobin with one mustache. Depending on the manufacturer, the length of the refueling trimmer line can range from 2 to 5 meters. The end of the trimmer line is inserted into the head in a special technological groove or hole, and the winding is carried out in the reverse work rotation of the bobbin side. On most coils on the outer side of the case there are marks in the form of arrows that indicate the directions of the movement of the trimmer bobin.

After winding, you need to leave the free end of 15-30 cm to strengthen the centrifugal force, which is determining when extracting a trimmer trimmer line in automatic and semi-automatic reels. The left end is extended through the coil work hole and make the head assembly.

Device and principle of operation of the clutch clutch of chainsaws

Modern chainsaws are equipped with centrifugal clutch couplings. This means that their work entirely depends on the torque of the motor, which at a particular moment in time gives out a saw.

Its main constructive elements are:

The principle of operation is as follows. When the saw is launched, the elements that are freely move in the radial direction, with the springs are tightened to the axis of the shaft. In this case, the torque does not enter the drum, which means to the asterisk and the guide. At the moment when the centrifugal force prevails over the power potential of the springs, the adhesion elements are weakened and compressed at the inside of the drum, initiating it. Together with him, the rotational cycle passes to the asterisk and the tire-like headset itself.

The main advantage of the clutch of this type is its slippage when the cutting part is suddenly inhibition, which does not stop the engine. As a result, the “heart” drank. The engines remain intact and preservation.

How to remove a coil from a trimmer and extract a trimmer line

Initially, before filling the trimmer line into the coil of the trimmer, it is necessary to extract it from there. Coil or tip is a device that is located inside the braid, bobbin or drum. The heads are of different types (depending on the manufacturers), however, the principle of replacing the trimmer line on the coil has the same. First of all, we will figure out how to remove the head from the tool, as well as how to get a drum with a trimmer line from it.

It is interesting!The replacement of equipment can be done directly on the tool, but if you do it for the first time, it is still recommended to remove the head, and study the detailed process of winding. After the technology is mastered, you can perform work on replacement on a trimmer of a motorcycle or a gas station. Instructions on how to promote a hand head on a trimmer, has the following look:

    Turn the instrument with the head to the top, and if necessary, cleanse it from pollution. Take two fingers of one hand by the cover of the cover (on the mowing head), which are located symmetrically to each other. After a light pressed inward, dismantle the protective cover from the drum

This process is not difficult, and as you know, it is not necessary to dismantle the entire head if you know how replacement is performed. When dismantling, consider the following nuances:

  • It is recommended to remove the head periodically to prevent the corrosion of the threaded connection. If you never unscrew the screw, then if necessary to do it will be difficult and even sometimes impossible
  • If the screw has a tetrahedral boring of the head, then for twisting you should select a screwdriver or bit of a suitable size to eliminate the licking of the faces on the head
  • When assembling the installation, a threaded seat should be treated with lubricants, for example, solidol or machine oil
  • If the edges on the screw are licked, then for its unscruptions you can use special clamping forceps
  • There are drums that do not require preliminary disassembly. To dismantle them, you should take up it, and rotate in the opposite direction of the direction of the clockwise

Knowing how to disassemble the drum, you should continue to clarify the process of replacing the trimmer trimmer line. Below the video shows a detailed process how to open a trimmer coil and disassemble it.

How to put a coil on a trimmer correctly

How to wind a trimmer line on a trimmer reel

Product coils can have different threads for feeding threads. It can be manual, semi.Automatic or automatic feed. Depending on this, it is necessary to wind the trimmer line. So how to tuck a thread into a reel? First, a cap is unscrewed on the coil (see. Video). If the thread on it is left.Handed, then you need to turn it clockwise, and not how it is usually done.

Such a thread is made so that during the operation of the product the trimmer head could not unwind. It will take about 5 meters of material to refuel the thread (see. A photo). It needs to be folded strictly in half, the center is inserted into a place specially designated on the device and wound in the direction of the arrow, which should be drawn on the coil, as in the video. After that, you just need to tighten the lid.

Country toilet-a mandatory attribute of a garden plot. Even if they are not going to build a summer dwelling, for the whole day.

The suburban cottages of the inhabitants of megacities are less and less reminiscent of garden houses, these are already quite modern “cottages”. Places for relaxation and hobbies.

Types of trimmer line

Thread for a trimmer can be divided into types by its diameter. It can begin with the smallest. 1.2 millimeters and reach 4 millimeters. The most commonly used is the diameter of 2 millimeters. But it is necessary to select it strictly individually, based on the specific model of the apparatus. Often the necessary diameter of the product is indicated in the passport for the product. Usually the more powerful the trimmer, the greater the diameter of the trimmer line should be. For example, it is best to wrap a thread with a diameter of 2.4 millimeters to a coil of motorcycles, and a thread diameter of 1.6 millimeters is suitable for a product with a weak engine.

Fishing lines differ in the type of section. It can be round (for mowing ordinary grass), square (for soft and often mowed grass), with sharp faces (for high grass), with notch (for thin grass), as well as complex (see. A photo). The latter can be refueling far from all types of devices. It should be noted that the trimmer line is intended exclusively for mowing grass. To cope with other plant species, it is necessary to use motorcycles with a sharp knife. The length of the threads that can be tucked in a trimmer can fluctuate from 10 to 100 meters.

Necessary tools

It is not even worth the master to start complex repairs without consumables and the necessary set of tools. Therefore, the owner of a faulty washing machine needs to be purchased or lend from friends:

The dismantling of the collapsed drum of washing machines with horizontal loading of all existing brands is performed according to the following scheme:

  • We block the tank with a wooden bar so that the hatch is below;
  • Using a key with rattle, we turn off the bolt, which fixes the pulley on the shaft;
  • We take out the pulley and twist the bolts connecting the halves of the tank;
  • Remove the back of the part from the shaft with a light blow;
  • We pull the bearings.

If the bearings have “closed” to the shaft, then it is recommended to use a car puller and a soldering lamp. The latter is needed for preliminary heating of the part.

To dismantle the indispensable tank, you need to cut the drum in half (strictly along the rib) with a canvas from a hacksaw for metal. One end of the canvas for convenience is wrapped with several layers of isolet.

Of course, you can use an electrician, but in hard.To.Reach places you still need a canvas from a hacksaw on iron.

Before disassembling a tank of this type, it is necessary to make many small holes-after 5-7 centimeters-along the rib, which will be cut, using a drill with a thin drill. These holes will be needed when assembling the part.

It’s time to move on to the features of dismantling the tank in machine guns of the most popular brands. First, consider a detailed scheme that allows you to remove the drum from the LG washing machine of any model. Preparatory part:

  • We unscrew in the lower part three screws and two more screws in the upper part to remove the front cover with the door (do not forget to disconnect the wires from the connector located near the lock);
  • Disconnect the lateral and lower cargo, fixed by bolts from the tank;
  • Remove the front fastener by uniting two screws;
  • Disconnect the three pipe from the distributor of detergents and throw this part outside the body;
  • Disconnect the pipe to the pump from the drum and pull the wires from the thermal attempt from the connector;
  • Remove the lateral springs (click the plastic clamps), disconnect the pipe of the press.Start and pull out the tank.
  • We remove the engine from the drum standing on the side by twisting two or four (depending on the model) bolts;
  • We turn the part with the rear part up and unscrew the pulley (do not lose the puck located under the nut);
  • Again turn the part and separate the tank from the plastic case;
  • We take a special groove and in turn we knock out the bearings from the cover, starting with a small.

If the bearings are “seized”, then we get them with light shocks on the shaft. To do this, it is recommended to use a copper hammer or strike not directly on the shaft, but on a copper adapter.

You do not need to throw old bearings, as they will be required to install new parts.

  • Install bearings in the lid (start with a large one). We take a hammer in our hands and apply light and uniform strikes on the rim of an old bearing, which acts as a kind of press. The installation continues until the appearance of a “deaf knock”. Excessive physical efforts are not necessary to apply cracks on the lid (a feature of the models of this brand).
  • Then we set the oil seal by hand. Any tool can be used at the same time.
  • We stuff the oil seal with a special lubricant (it is recommended to use exclusively “Indisitian” hydraulic-2).
  • Plant the lid with bearings on the shaft and immediately fix the pulley (do not forget to put a restrictive washer under the nut).
  • We apply a thin layer of conventional silicone lubricant into the rim of the lower half of the tank, and then connect both halves of the drum, twisting the screws (the order does not matter).

Disassemble the drum of a broken washing machine Samsung Diamant is much easier due to design features. Specialists consider the cross.Cutter connecting a tank with bearings to the weakest place of these washing machines.

How To Remove A Lawnmower Blade Adapter

It is quite difficult to twist the bolts from the “paws” of the cross.Fiber, since they are “planted” on the paint. Therefore, it is recommended to previously apply a few light shocks on the fasteners with a rubber hammer used when laying tiles.

  • We clean all the details of dirt and rust;
  • We change the bearings, the oil seal and the cross (the bolts of the last part must again be “planted” on a rapidly drying paint);
  • We stuff the oil seal, and slightly lubricate the sleeve on the shaft with special smokes;
  • Carefully install the drum in place in manual mode;
  • We connect the halves of the tank with screws;
  • We install equipment in the reverse order.

Installation of a new trimmer line on a trimmer coil

Equipping the coil with a new trimmer line is performed in the reverse order. The procedure looks like it is described below, regardless of the model of the lawn mower:

Step one: fixing and styling

Fold the end of the trimmer line in half. Place the workpiece above the coil on each side of each half of the winding area. Wrap both halves completely around the winding drum. Stretch the trimmer line through the loop.

The procedure for preparing trimmer line in the field of both wound sections of the drum. The loops are laid in specially made cutouts, after which the winding of the trimmer line is performed in each area

Pull the trimmer line quite hard and put the knot in the groove made on each side of the winding drum.

Step two: winding cutting material according to sections

The next step is to turn the trimmer line in a circle of coil, observing caution. It is necessary that each half be filled with “its own” winding, exactly, without intersections

Usually on the hull of the winding drum you can see the arrows indicating the direction of winding. This moment should be borne in mind, filling the reel with a trimmer line.

Step Three: The Club of the Head Noner

Stretch the ends of the trimmer line through a pair of oval cuts of coil. Replace both goals and a spring (if any in the design) with new elements included in the package. Bend both ends of the trimmer line at right angles.

The last technical stroke of the process of replacing the trimmer line on the trimmer is to put the cover on the head with subsequent fixation by pressure and slight turnover.

Let each end into the hole, which is at the base of the winding drum. Install the coil in the inner area of ​​the head with an emphasis on the spring. Put the lid, leve on the base and light pressure down with a small rotation counterclockwise, put the cover on the tongues of the latch. This is where the replacement procedure is completed.

How to make repair of the lawn mower with your own hands?

Those who have land are very familiar with what struggle is weed.

Especially when it often rains and the grass grows not by the day, but by the hour. Earlier, and sometimes even now, this issue was resolved with the help of a good old braid.

But technologies are not standing still and now in this case, assistants such as electric and gasoline lawn mowers help.

The gasoline mower has several significant advantages over electric, such as mobility and lack of danger of electric shock. But there are many drawbacks, for example: high price, a lot of noise, expensive fuel and significant weight.

Electric mowers are cheaper, easier, work on inexpensive energy, and are not difficult to maintain and repair. These advantages become the main reason for their great popularity among buyers of this type of technique.

remove, drum, lawn, mower

But despite the pretty good quality, improper operation and a lot of load, they can disable the device. In such cases, you should not immediately carry the device to the repair shop, but try to find and eliminate the cause of the breakdown yourself. Over, as mentioned above, electric lawnmands do not have as many nodes and details as gasoline.

The main thing is to have some tools and faith in yourself. In this article, I will just show you how I did my own repair.

remove, drum, lawn, mower

AL-KO, the lawn mower of the company, has serious problems in work, namely: the engine stop without load and its strong overheating, was taken as an example. The motor stops, buzzes and start it again, only repeated pressing the Start button helps. The button has to restart almost every 30 seconds, and with further work and more often.

Of course, you can work, but it is very annoying and gives the feeling that somewhere the problem is. Therefore, I wanted to figure out where?

After the mower was working within an hour, the engine temperature was measured. It was impossible to touch him with a finger. He directly radiated heat. If you continue to pay attention and continue to work on such a mower, an electric motor will inevitably fail.

The lid is held on six screws with a hat under a cross screwdriver.

Unscrew these screws and remove the lid. Upward.

Having removed it, you can see the impeller, the capacitor, two connectors and the engine itself.

At first glance, no special problems are invisible. The engine winding darkened slightly from the temperature, but so far it is not critical.

Rice. 5. Impeller, capacitor, two connectors and the engine itself

To more carefully inspect the capacitor, it is necessary to unscrew the mount and pull it out.

The capacitor of some external damage did not show.

Next, try to twist the impeller. It is mounted on the axis of the rotor and rotates rather tight.

And the reason for such severe rotation is a mechanical brake, which for safety stops the engine rotation when the power is turned off.

It looks like a sleeve that moves freely from top to bottom, along the rotor axis.

Когда напряжение на двигатель не подано, эта втулка прижимается верхней частью о крышку, на которой приклеено две резиновые полосы. Thus, the knife is inhibited on the rotor shaft.

When feeding, the brake sleeve under the influence of the magnetic field is drawn to the center of the rotor and provides free move.

With a careful examination, this sleeve with the brake noticed that at the time of turning on the engine, the brake is retracted and gives the shaft free rotation, but after 2-3 seconds it is released again and begins to slow down the motor. This should not be. Hence the stop of the knife during operation and overheating of the engine.

To find out what is the reason for this work, you need to remove and disassemble the engine.

To do this, disconnect the connectors and put the device on the side to get to the clamping screws. Access to them closes a knife with mounting elements.

To remove it, first you need to unscrew the knife bolt (cm. Figure below).

Direction of rotation, like a regular bolt, and not with left thread. That is, unscrew it counterclockwise, and tighten the clock.

The head of the bolt is plastic, so using the key, it must be well planted so as not to “lick” the edge.

After extracting the bolt, the knife and its plastic disk are removed.

Under it is a height sleeve. With its help, you can slightly lower the knife.

Adjustment is carried out by the washers put under the sleeve (see. Drawings below).

We remove everything, only the engine shaft and the hexagonal screws of its fasteners remain.

The key for these bolts has a distance between faces of 6 mm. Unscrew them counterclockwise. Removing the last screw, with one hand, hold the engine.

Next, put the mower on the wheels, and clasping the engine with our hands. We raise it.

To disassemble the motor, you need to free tightening studs. We unscrew them all.

Remove the impeller with two screwdrivers.

We proceed to the removal of the back cover. A wooden block and a hammer will help this.

But first you need to mark the position of the covers with something sharp to the engine body.

Put the engine on the side and hit with a hammer, through a wooden gasket, on the rear shaft.

The motor at that moment should hold another person.

We hit until the axis comes out of the bearing to the end.

Magneto Design and a scheme of work

The transformation of rotation energy into a high.Voltage discharge and the formation of a spark that ignites the fuel mixture. In the internal combustion engine, this detail is called Magneto, because in it alternating current is generated from the rotation of a constant magnetic rotor or anchor.

Magneto constructively consists of 2 windings: the highest and low voltage. The condenser with interrupter contacts are parallel to the latter. Whereas the conclusions of the winding of the highest voltage are connected to the candle and body. They are both wound on a core, between the poles of which a spinning magnet is installed, magnetized longitudinally.

Trimmer line on trimmer

The measured and neat dismantling of the spit of the braid coil makes it possible to go directly to the winding of the trimmer line. Design features of the head, the number and location of the fixing holes dictate the sequence of actions when performing this operation, and also determine the methods used. Today, there are several varieties of coils depending on the number of antennae antennae and refueling methods:

Trimmer coil with one osmus

Many owners and experts note the simplicity of the operation and refueling of bobin with one mustache. Depending on the manufacturer, the length of the refueling trimmer line can range from 2 to 5 meters. The end of the trimmer line is inserted into the head in a special technological groove or hole, and the winding is carried out in the reverse work rotation of the bobbin side. On most coils on the outer side of the case there are marks in the form of arrows that indicate the directions of the movement of the trimmer bobin.

How To Remove The Flywheel On a Lawn Tractor with Briggs & Stratton Engine.

After winding, you need to leave the free end of 15-30 cm to strengthen the centrifugal force, which is determining when extracting a trimmer trimmer line in automatic and semi-automatic reels. The left end is extended through the coil work hole and make the head assembly.

Trimmer head with two antennae

After extracting the spray from the coil body, we determine the number of streams for winding trimmer line (1 or 2). There is no fundamental difference between bobbins with one and two grooves, but with a careless refueling in a paired groove, there are problems with operation. Due to the likelihood of weaving neighboring tools, a situation may arise when after the wear of the working antennae it is impossible to extract new.

Regardless of the number of streams for refueling, a trimmer line is taken from 1 long.5 to 3 meters. The winding must be carried out in reverse rotation of the head to the side, since the winding in the direction of movement will lead to the fact that the trimmer line will not be removed from the bobbin. After the trimmer line is tucked into the coil of the trimmer free ends (15-30 cm) we extend into special holes. Next, collect the head in the reverse disassembly order and check the performance. Do not worry if the ends of the two antennae are very different in size, because when the trimmer is launched, the knife installed on protection will cut off the excess.

Trimmer head with automatic line dressing

In some models presented on the market, a coil with an automatic winding mechanism is installed. It is enough to correct the owner and fix the ends in the head, and the winding operation will perform the tool itself when included in the operating mode. It is almost impossible to incorporate the trimmer line into a trimmer with such a head, since the coil independently determines the position of the antennae. The advantages of the automatic head of the trimmer include the simplicity of trimmer line refueling, and the disadvantages are frequent breakdowns of the mechanism due to the complexity of the design and the high cost.

If the trimmer line is not lengthened by a light blow of the trimmer button on the ground, the prerequisites for this usually the following.

Option 1. Snack, t.E. Clamping cord between turns. This problem usually occurs if the user wraps the trimmer line on the coil unevenly, crossing the windings or wrapping it without tension. In the latter case, when the mower rotates at high speeds under the influence of centrifugal force, the cord begins to drag on, under the influence of which the interspersonal clamp of the braid trimmer line may occur. To eliminate obstacles, you need to disassemble the coil on the trimmer and correctly rewind the cord, in other words, even rotates with good tension.

Option 2.4. Very short ends stick out of the head. When hitting the ground, the rod may not fall out if its ends protruding from the head are not long (short). Then centrifugal force is not enough to stretch the trimmer line. Therefore, it is necessary to hang the unit (turn off the engine in another way, disconnect the electric trimmer from the network) and pull the trimmer line manually, after pressing the button.

Option 3. Little line is sealed inside a mower. This makes the coil stop and do not even rotate when you press the button. This is mainly happening for several reasons: low quality of the cord, overheating of the coil during prolonged operation of the machine and the effect of a mowing trimmer line on hard objects.

  • First, the cord of third.Party manufacturers that you like is made of low.Quality and fusible materials that do not withstand mechanical and thermal loads. Therefore, it is necessary to give preference to “branded” fishing.
  • If you have a trimmer line of an unknown owner, and it is often soldered during operation, then, of course, follow the example of some users who, after filling the cord in the coil, moisten it or silicone lubricant (from a spray can) or mineral oil). This procedure significantly reduces the possibility of soldering turns of the mowing trimmer line.
  • The trimmer line can also be soldered if during the mowing it falls into a solid object (stone, fence, dry branch, etc. D.). During this time, it stretches a little and stretches to the head at high speed. The cord heats up from friction, and its coils stick together. The only thing that will be done to eliminate this problem is to open the trimmer coil and rewind the trimmer line.

There are situations when the Trimmer user notices very quick trimmer line consumption. Here he never pressed the button button to lengthen the trimmer line. A prerequisite for spontaneous lengthening of the trimmer line by cutting a special knife on the machine body is a lack of spring in a mowing head. Often beginner users of mowers, trying to load the trimmer line into the coil, forget to install a compressed spring in the head, in other words, completely lose it when opening the lid, and then they do not even suspect its existence.

The trimmer line also expands without using the button if the spring is weakened. If the spring check confirmed this fact, then you need to insert several goals under it to increase the characteristics of the pressing.

The owners of the trimmers, mostly beginners, in confusion, next to the panic, when the coil has to change the cutting tool or trimmer line. Often, when trying to unscrew the lawn mowing head, users simply make it unsuitable for use, not suspecting that it is unscrewed in the opposite direction To prevent this, if you need to change the tool, we recommend that you join the step.By.Step annotation below.

  • Before pouring the rod into the coil, turn off the engine bureau, as it is also called, de.Energize the electric trimmer to avoid injuries that occur when the cutting tool is accidentally turning.
  • Unscrew the attached nozzle of the transfer shaft. To do this, it is necessary to fix the shaft by leaving the opening on the puck and inserting an iron bar there or a screwdriver there.
  • Unscrew the nozzle. You should know that the thread on the shaft remains. Therefore, turn the trimmer coil to the right, in other words, clockwise.
  • Disassemble the mowing head. In most cases, the main cover is attached on the clips. To remove it, you will need to lower these clamps onto the case, squeezing the edges of the lid. If there is a pass, if your trimmer has an automatic mower with a button below, then the nozzle should be disassembled carefully, since there is a chance of a spring loss, which sometimes flies away when removing the lid. ,
  • Cut the required amount of fishing. Usually its length is 5 meters. Use the cord of the same diameter that is indicated in the note to the tool. It is not recommended to exceed the largest diameter of the mowing trimmer line, as this will increase the load on the engine and increase gas mileage.
  • Find the middle of a piece of cord, folding it in half. You will get a loop.
  • The coils are cut special grooves inside (there are holes). Insert the loop of the trimmer line into this groove.
  • Wind a trimmer line on a reel, turning it counterclockwise. The cord must be filled very evenly, the turns you need to put it in a non.Overlap and with good tension. After the winding is completed, leave the free ends of the trimmer line about 20 cm long and fix them in grooves on the sides of the coil.
  • Collect the mowing head. Do not forget to completely assemble the nozzle spring and washer (if available). Insert the coil into the housing and pass the ends of the cord through the holes or eyes.
  • Put on the lid and fix it with latches.
  • Screw the nozzle back to the gear shaft, also fixing it with a screwdriver. Turn the trimmer coil to the left (counterclockwise).

Trimmer heads: types and principle of action

The domestic market offers the owners of trimmers of the coil of several types: manual, semi.Automatic, automatic and universal. They differ from each other in both the way of serving the trimmer line and the principle of its charging. You can also wrap the trimmer line in different ways. According to this principle, the coils are classified into rapidly charged and collapsible.

Before you purchase a trimmer and/or buy spare coils for it, you must definitely familiarize yourself with exactly which consumables are suitable for a particular model

This is important, since bobbins of different manufacturers can differ not only in the methods of supply and refueling of the cord, but also to the axis of the mount, type of thread, as well as the diameter of the trimmer line used. For example:

  • The fastening axis can be fixed (fixed) or rotating 90 °, 180 ° or 360 °;
  • For low.Power trimmers, a trimmer line with a diameter of 1.3 to 1.6 mm is suitable, and for more productive. Up to 2.0 mm;
  • Professional trimmers, as a rule, are equipped with universal heads with a diameter of the cutting cord from 2.5 to 4.0 mm.

Manual bobbins

A manual mowing head is a coil in which the cutting cord during wear is stretched by the owner of the trimmer on its own. To do this, turn off the tool, remove the head and with the help of hands stretch the trimmer line to the required length. However, despite some inconvenience, this type of head is considered the most reliable.

Bobbins with semi.Automatic control

The semi.Automatic coil installed on the trimmer allows you to serve the trimmer line using the centrifugal force that arises when it rotates. In order for the supply to be carried out, you need to touch the head of the coil to the ground and at the same time press the button that opens the anchor mechanism. This key is located on the control handle. At the same time, turning off the trimmer is not required.

Bobbins with automatic control

In an automatic type, the supply of the cutting cord occurs when the speed of the trimmer engine is changed. To pull the trimmer line out, reduce, and then increase the speed of rotation of the engine shaft. As a rule, the coils of this type are equipped with a metal core, due to which their breakdown is practically excluded.

Bobbins are universal

The universal type of heads differs from its analogues in that they can be installed on various models and electrimmers’ models. They are characterized by high strength and reliability during operation.

Bobbins are quick.Charged

Coils of this type allow you to refuel a new trimmer line without disassembly. To do this, one of the ends of the cutting cord is stuck inside the bobbin, and then wrapped several times around its surface. After the required amount of trimmer line is wound, the latter is cut off.

Bobbins collapsible

To refuel the trimmer line into the head of this type, it must be removed from the grass.Shirt and disassemble. Having wound the required amount of cutting cord, the coil is collected and returned to the place.

Video: how to remove the wheel from a lawn mower

Therefore, without special tools, I was able to solve a difficult problem. The homemade pulley was very simple and effective. Only a couple of iron and bolts helped.

380 volt 2.2 kW electric motor, I want to adapt it for the lawn mower, this idea has long been spinning in my head, and I am sure that I will show the result.

Pulley. This is the wheel on which the groove passes. The wheel is attached to the shaft and plays an important role in the design of the engine responsible for the transmission of torque from the shaft to the drive belt. The idea of ​​how to remove the pulley from the engine is necessary when the parts are subject to repair or replacement with a new engine.

This article describes current methods for removing pulleys and some tips for their use.

How to remove the pulley from the motor: choosing the right method

Universal technique, which often justifies itself, is a simple mechanical effect. Blows of light from the opposite sides of the pulley, in turn. Thus, the pulley gradually shifts from the place of landing to the shaft and can be removed.

In more complex cases, the list of necessary actions is planned on the basis of the following factors:

  • Method of attaching the pulley to the engine shaft (type of device);
  • The state of surfaces at the junction (depending on the life of the operation, the exposure of corrosion materials)

Under what conditions you can remove the pulley from the engine without a puller?

There are a number of cases when, for an effective solution to the issue of how to remove the pulley from the engine, it is impossible to remove the pimp. However, the use of special devices is usually not required if:

  • The pulley was installed without compression, t.E. The diameter of the shaft did not exceed the diameter of the pulley of the pulley;
  • The connecting surfaces were not deformed during engine operation.

Small power electric motors provide reliable pulley mounting using clicking using threaded joints or fixing elements (rings, washers). In such cases, it is enough to unscrew the nuts (or remove the rings) to separate the pulley from the engine. The situation is complicated if a ring with gear edges is used at the mounting point.

Before unscrewing the connecting elements, it is recommended to tighten the pulley under pressure. To prevent deformation of the pulley, wooden gaskets are installed between the relief plates and the surface of the clamped part.

The method of heating

If the thermal method was used to fix the pulley based on the expansion of materials, metals, in particular, during heating, then to remove it, its thermal effect on the pulley will be required:

  • Due to the heat released along the edges of the pulley, the diameter of the hole increases by the fraction of the millimeter and, accordingly, the degree of clamp on the shaft decreases;
  • After that, it becomes possible to push the part from the seat, tapping it in series from different ends.

What to look for when using this technique:

  • One.Time heating may not be enough, especially with a large diameter of the pulley hole;
  • The shaft should be reliably isolated from exposure that increases the temperature of the pulley, since in the case of indirect heating of the shaft, the adhesion of the elements will only increase;
  • If this happens, wait until the elements are completely cooled, and repeat the procedure.

Depending on what material the pulley and the shaft are made of, another strategy can be chosen, in which, on the contrary, the shaft cools.

Pip removal application

Before removing the pulley from the engine shaft, you can install a special device. A puller whose device is simple. The design includes:

  • A metal plate with a hole in the center and narrow grooves;
  • The nut is welded to the stove;
  • Bolts (one size, with a recess at the end, must correspond to a welded nut, the other two should be less).

The disadvantage of this method is the need for a slight violation of the integrity of the pulley, on the surface of which the pulley is attached:

  • The plate is attached with two bolts to the pulley;
  • The third bolt begins to screw into the central nut, while at the end it rests on a metal ball, previously fixed in the centering position of the shaft;
  • When the bolt is screwed up, squeezes the plate of the puller from the shaft, gradually removing the pulley from the saddle.

It is likely that the bolt move will be insufficient to move the part. In this case, try to insert additional nuts for the side bolts.

Thus, knowledge of the basic methods of disassembly and the use of simple tools will help you choose the best option and quickly separate the pulley from the shaft.

Those who have land are very familiar with what struggle is weed.

Especially when it often rains and the grass grows not by the day, but by the hour. Earlier, and sometimes even now, this issue was resolved with the help of a good old braid.

But technologies are not standing still and now in this case, assistants such as electric and gasoline lawn mowers help.

The gasoline mower has several significant advantages over electric, such as mobility and lack of danger of electric shock. But there are many drawbacks, for example: high price, a lot of noise, expensive fuel and significant weight.

Electric mowers are cheaper, easier, work on inexpensive energy, and are not difficult to maintain and repair. These advantages become the main reason for their great popularity among buyers of this type of technique.

But despite the pretty good quality, improper operation and a lot of load, they can disable the device. In such cases, you should not immediately carry the device to the repair shop, but try to find and eliminate the cause of the breakdown yourself. Over, as mentioned above, electric lawnmands do not have as many nodes and details as gasoline.

The main thing is to have some tools and faith in yourself. In this article, I will just show you how I did my own repair.

Why you need to put a knife on a trimmer

The trimmer with a knife installed on it is most conveniently used for a more comfortable mowing of high and loaded grass in the country. The trimmer line on the motorcycle is in such cases does not cope. Thin torn very quickly. Using Tolstoy 2.3 mm cord or homemade rods with cables forces the vegetation to wind up on the rogue. This increases the load on the engine. As a result, the piston group and other mobile units of the unit wear out very quickly.

If the mowing of a weeds is produced by an electric trimmer without a knife, only with a trimmer line, even a thick with a figure section, the problem cannot be solved. There is always a risk of overheating the electric motor and disable flexible shaft. And it’s all in a large torque of the electric motor. The grass wound on a spindle creates strong resistance to the shaft resembling a speedometer cable that does not withstand and twist.

In order to protect the equipment from premature wear, manufacturers have provided the ability to install special knives on trimmers. The design and shape of existing cutting elements allows you to easily cope not only with coarse and outgrown with grass, but also to successfully fight the young shrub.

What is an adapter?

The adapter of the lawn mower is an adapter with two blades that connects the cutting element with the engine. From the side of the Rezak there are special rods designed to fix the knife. The design of the structure is carried out by the central bolt. There are grooves from the engine that coincide with the bell toe. When choosing an adapter, it is necessary to take into account the inner diameter of the central hole of the cutting element.

A two.Blade adapter performs several functions at once:

  • Allows you to install knives of different sizes and configurations on the engine;
  • When working in conditions of increased loads, the adapter breaks down, protecting the elements of the motor from breakdowns;
  • It is used as a pulley of the wheel drive.

If you remove the lawn mowing knife and plan to install an element of a different size or shape, you will have to replace the adapter. The total number of varieties of adapters is about 40. Manufacturers make parts from high.Strength, deformation and abrasion of a metal alloy, which provides the adapter with a large working resource.

Trimmer heads: types and principle of action

The domestic market offers the owners of trimmers of the coil of several types: manual, semi.Automatic, automatic and universal. They differ from each other in both the way of serving the trimmer line and the principle of its charging. You can also wrap the trimmer line in different ways. According to this principle, the coils are classified into rapidly charged and collapsible.

Before you purchase a trimmer and/or buy spare coils for it, you must definitely familiarize yourself with exactly which consumables are suitable for a particular model. This is important, since bobbins of different manufacturers can differ not only in the methods of supply and refueling of the cord, but also to the axis of the mount, type of thread, as well as the diameter of the trimmer line used. For example:

  • The fastening axis can be fixed (fixed) or rotating 90 °, 180 ° or 360 °;
  • For low.Power trimmers, a trimmer line with a diameter of 1.3 to 1.6 mm is suitable, and for more productive. Up to 2.0 mm;
  • Professional trimmers, as a rule, are equipped with universal heads with a diameter of the cutting cord from 2.5 to 4.0 mm.

Manual bobbins

A manual mowing head is a coil in which the cutting cord during wear is stretched by the owner of the trimmer on its own. To do this, turn off the tool, remove the head and with the help of hands stretch the trimmer line to the required length. However, despite some inconvenience, this type of head is considered the most reliable.

What is the problem?

A lawn mower knife rotates at high speed. It has a central hole for fasteners, and both parts from this hole should have the same weight for uniform rotation. What happens when an inexperienced user is taken for sharpening?

  • In the process of sharpening, more metal is removed on one of the sides than on the other.
  • An imbalance occurs: the knife “hits” when rotating.
  • The imbalance leads to a Rapid failure of bearings: the lawn mower requires repair.

If you decide to sharpen the knife yourself, you need to keep in mind that this must be done carefully, slowly and taking into account the nuances that we noted above. Here are some tips that will help to cope with the task.

An excellent assistant in the farm is the lawn mower. With its help, they put things in order and give aesthetic appearance to herbal plantations (lawns). In order for the lawn mower to work properly, it is necessary to monitor the condition of its knives. Proper sharpening of the lashes of the lawn mower will bring the expected result from its use. Self.Sharpening of the blades of the lawn mower is strongly not recommended, qualified specialists should be done by this. Sharpening master, has certain skills and a special tool for this. Having trusted the work to the professional, the sharpening results will be the most positive. This will also save its free time and get rid of the undesirable breakdowns of the lawn mower.

Below the lawn mower there are blades (there may be two or one) that rotate the grass with rotating movements at high speed. It should be emphasized that the lashes of the lawn mowers should cut off the stalks of the grass, and not tear it out. To achieve this effect, knives for lawn mowers should always be sharpened.

Sharpening of a lane of a lawn mower is a complex and time.Consuming process. But our masters are ready to share their experience.

How to sharpen a knife for a lawn mower properly

A knife for a lawn mower before sharpening must be pre.Removed. Initially, you need to turn off the lawn mower and, for more confidence, unscrew the spark plugs or disconnect the device from the mains. To remove the lawn mowing knife, it must be turned onto the side, then unscrew the knives attaching bolts and gently remove the blades. To comply with safety rules, while removing the lanes of the lawn mower, it is best to use special gloves that protect hands from possible injury on the blade of the apparatus.

Knife sharpening

We identify the cause of the malfunction

To repair the lawn mower yourself, it is best to be guided by the principle of “from simple to complex”. First, check if there is enough gasoline in the tank. If the mower stopped starting after wintering, it is worth draining the old fuel and replace it with a new. Sometimes low.Quality gasoline comes across, which can give a precipitate or even delay in the winter, and some gas mowers are very sensitive to fuel quality.

If there is confidence as gasoline, but the lawn mower does not show signs of life, the next thing you need to do is check the spark. To do this, remove the wire with a cap from the candle and twist it with a special candle key, which should go with the lawn mower. Then throw the cap on the candle, attach its threaded part to the metal part of the engine and ask someone to pull the starter. At this moment, a bright blue spark should appear, which is clearly noticeable even during the day. Keep in mind that you need to lean the candle against the clean metal surface of the engine, which is not covered with paint and which can be current.
