Possible malfunctions of a trimmer gearbox for grass, a gas mowing gearbox, and gearbox Motokos

Knowing the internal device of the lawn mower and the principle of its operation, you can easily eliminate the malfunctions with your own hands. Some breakdowns are most often found and they are distinguished as the main.

  • The engine malfunctions should be sought if the lawn mower does not work or does not even start. It is also worth paying attention to this part of the braids for grass, if during operation unusual noises are heard or strong vibration is felt. Clotting of the air filter can also lead to problems with the engine.
  • If the fuel does not enter the combustion chamber, then you should look for the cause in the suction of the fuel filter. It is also worth looking at it if the tool does not work at low speeds.
  • The starter’s grille was clogged. the reason for the engine overheating and its termination. The starter can also fail when the cord tears when it is too sharp.

Malfunction. the knife does not rotate, the coil.

The reason is the wear of transmission elements.

The data transmission of the gasoline consists of a lower gearbox, shaft and upper gearbox (cup). Consider them in more detail.

The gearbox consists of a housing and a gear pair that are susceptible to wear.

This is due to the lack of lubrication in the gearbox.

Do not neglect this procedure during the operation of the lawn mower.

Lubrication control will extend the life of the gearbox.

There are sets of gears for these reducers on sale, but their cost exceeds 60-70% of the cost of the gearbox, moreover, the process of their replacement is laborious, a simple solution will be-replacing the gearbox with a new.

The transfer of traction from the engine to the gearbox is provided by a hard shaft, at the end of which there are slots. Due to the lack of lubrication in the gearbox, slots can be worn out. In this situation, only replacing the shaft with a new. Please note that there are 3 types of shafts (7 slits, 9 slits and “square”). The length of the shaft, as a rule, on such models 152mm. The replacement is very simple. we dismantle the old shaft. install the new.

How to disassemble a gearbox of a trimmer for grass

In order to disassemble a trimmer gearbox for grass, you need.

  • Remove the gearbox from the pipe, loosening two conjugate bolt under the gearbox.
  • Wash the gearbox with a brush, for example, in gasoline without oil and dry.
  • Run the ends of the locking ring and take it out.
  • The second stop ring and the second.
  • Then it is necessary to heat the trimmer gearbox for grass, the motorcosa gearbox or the reducer of the lawn mower by an industrial (technical) hairdryer at the temperature of the outgoing air at 600 ° C.
  • After that, strong blows of a wooden bar on the upper part of the gearbox, knock out a driven shaft with a bearing and a gear (first you should try to knock out bearings without heating). It is only necessary to hit a wooden bar, since a metal, for example, with a hammer, can be broken down by the case.
  • In the same way we remove the leading shaft with a bearing and a gear (we strongly heat the place where the bearings are sitting and with the blows of the wooden bar on the body of the shaft, we knock out the shaft with two bearings and the gear). How to disassemble a trimmer gearbox for grass, gearbox gearboxes and gearbox motokos. In order not to heat, you can try to use the set.

The assembly of the gearbox of a trimmer for the grass is carried out in the reverse order of disassembly (assembly after buying and replacing spare parts). It is much easier to collect a gearbox than to disassemble. everything is going, literally, with fingers. Sometimes you need to gently take up something, install stop rings and check whether the driven shaft is spinning by hand.

If you decide to replace the trimmer gearbox for the grass with not original, then in the new gearbox you should pay attention to the diameter of the pipe for which the gearbox (more than 25.4 mm or 26 mm) is intended, the diameter of the drive shaft (more than 8 mm), the size of the square shaft square (more often 5 mm or a star for 9 teeth) and security mounting on the gearbox, as well as on a nut (with left thread, more often M10x1.25).

Modeling recommendations

Do not immediately, filling the mixture, go into a difficult fight with thick vegetation. It is necessary to start with the, which will help to develop moving parts to each other and strengthen the skills with the device.

  • Do not immediately run the engine for maximum speed. It is best to dwell on the maximum torque moment.
  • Overheating is not allowed. However, you can’t mow on an unheated engine too!
  • The engine cannot be overloaded. The throttle should be opened by 2/3 of the course.
  • After running in, the oil drains.

These rules will allow an increased lubrication of parts of the piston group, which will become a guarantor of a long operation of the entire device.

How to make a high.quality fuel mixture

  • Gasoline is poured into the tank to the corresponding mark.
  • Two.stroke engine oil is poured into gasoline, and not vice versa, to the level of the mark
  • The mixture is shaken several times until a homogeneous substance is obtained.
  • If there is no special container in the package, use a regular gas cylinder. Fold the mixture in this ratio of gasoline / oil 32: 1.
  • It is not recommended to prepare the mixture directly in the fuel tank of the trimmer for grass.

At the very beginning, the technical condition is being tested:

  • The hinges of levers, ball supports, shock absorbers on VAZ 2107 and springs are being examined. If there are no visible defects in components of the elements, the lifting of the vehicle is debugged.
  • Then the support bearing is checked for the presence of gaps.
  • After the silent blocks of the rubber.metallic type are checked.
  • The lower ball supports are diagnosed.
  • An inspection of the stability stability of the transverse direction is carried out. It should not have any cracks, no scratches, no other damage to mechanical origin. Drying bushings and damaged brackets are not considered a format.
  • The pair of the front shock absorber is checked.
  • The state of the front springs is studied.

How to lubricate the gearbox of a trimmer for grass?

At the top of the case where the gear block is located, there is a technological hole, which is covered with a screw during the trimmer for the grass. This screw is unscrewed, and 1.5-2 million lubricants are introduced from the nose of the tube into the hole. If the purchased composition has a different packaging, then a regular syringe will fit into the hole to enter the mixture. After the screw is placed in its rightful place.

This operation, regardless of the user’s recommendations, should be repeated after every 10-15 hours of work of the trimmer for grass. In other cases, the gear lubrication is replaced and updated when the device is preserved in front of the winter, repair the assembly, washing and cleaning the gears at the beginning of summer, etc.P.

Being in a disassembled state, before applying a new lubricant, it is worth initially to completely remove the remaining the old mixture, even if they are not polluted and not oxidized.

After applying a new lubricant, you should handle the shaft a couple of times to make sure that the composition was equally distributed on all surfaces of the gearbox.

In the process of lubrication, it is important to pay special attention to the following components of the trimmer for the grass:

  • Bearings with a worn seal through which the remnants of the lubricant during the operation of the unit could go out. With a lack of lubrication in this case, the device begins to vibrate markedly. This often happens with Chinese models, when choosing which it is worthwhile to think in advance about the replacement of the bearing knot with the highest quality analogue, for example, the Swedish SKF.
  • Dog with a starter coil, as it often touches the grooves on the flywheel when the drive is turned on. In addition to mechanical wear, in this case there is also a mechanochemical corrosion between the compounds of the dog and the flywheel, since these components are made of different materials. a dog made of steel, flywheel. from aluminum.
  • A flywheel, on the surface of which the remains of grass usually accumulate, and as you know, thickened herbal juice has excessive resistance.

The lubricant for the gearbox of the trimmer for the grass is selected based on many parameters described above. Carefully consider all of them, and then the device will serve you regularly for a long time, always delighting with a trimmed lawn and a well.cleaned territory.

With frequent, intensive use of motorcycles, the gearbox can start to heat up or make sounds uncharacteristic for its normal operation, for example, rattle. This indicates that the mechanism must be lubricated. If this is not done on time, then more serious problems will arise (for example, gears will be quickly worn out and you will need to replace them), up to jamming. Other breakdowns also arise with the transmission mechanism. Reducer repair and lubrication can be performed independently. for this you just need to familiarize yourself with the features of these work and stock up on some available tools.

Reducer device trimmer for grass

The gearbox of a trimmer for grass is a node that transfers the rotational movement of the engine shaft to the knife or fishing line. It is located on the lower end of the motorcycle rod. The gear node is also designed to lower the engine speed of the trimmer for grass.

The mechanism consists depending on the model of the motokos of several gears rotating at a high speed. As a result of this, they heat up due to severe friction. If the lubricant is not enough, or it is not at all, then the process leads to a strong overheating and failure of the parts, and, accordingly, the need to carry out a difficult repair. So that this does not happen, lubricate the gear node in time. Misused gearbox is presented in the photo below.

The reducers of modern trimmers of different models from various manufacturers differ from each other by the design and the size of the seat. It happens:

The most common diameters of round seats are 24, 25.5 and 26 mm.

Motokos is equipped with gearboxes with different types of gears:

  • conical;
  • worm;
  • spiroid;
  • cylindrical;
  • planetary;
  • wave;
  • combined.

Drive shaft and gearbox are very loaded nodes of a trimmer for grass, which are largely susceptible to wear. Between them, the movement is transmitted due to the adhesion of the teeth of the gears located at different angles to each other. Effective gear works only if there are no mechanical damage. In this case, the mechanism should not overheat, otherwise its jamming may occur.

How to mow a trimmer (with a metal knife)

First go around the site. a) to determine:. the boundaries of the site on which you will mow with a trimmer;. where are plants in the grass that cannot be cut (flowers, bushes, seedlings); b) in order to determine the place of the beginning (to begin to mow a trimmer from the very light area in order to create an open place in order to move to greater grass to see the spin area); c) to determine the direction of the mowing with a trimmer (depending on the presence of ditches, slopes and inclination of grass); d) to determine the methods of spitting by a trimmer:. in folds. if the plot is flat with flat grass (so that there are fewer transitions);. with the transition back to a clean place, when the riding grass is running (its slope should be directed forward);. the mowing across the large slope (it is much easier to mow a trimmer across the slope than to rise and sink along the slope).

Put a metal knife: weed or hay. Protection, t.e. The fence of the knife is mandatory (without additional protection for the trimmer head). to mow a trimmer, you need to assemble in order: a leash cartridge, a metal knife (you need to put it without distortion), a supporting cup, a mounting flange and screw the nut (left thread);. insert a stopped pin and crank up a metal knife to lock the output shaft of the Husqvarna gearbox;. tighten the nut with a key with a force of 3. 5 kg/m;

When a trimmer spent with a metal knife, you need to set:. the speed of the knife, depending on the irregularities (to mow the trimmer cleaner and faster);. working capture of the disk: between 8 and 12 hours (when the knife moves to the left);. reverse move (can be a worker, sinking or idle);. gas (on load);. on even: the angle of inclination of the knife and the width of the mowing (more);. the height of the cut (to make it easier to mow a trimmer or to cleaner);. where to move (along the ditch, along the slope of the grass, along the site);

11 hours) and to the right with a slope by the handles to the right (sector

1 hour), and do not rush. To mow the trimmer cleanly and so as not to “dig” the earth;. during work (and turns), do not forget to look around!: one.To notice the gesticulation of others, drown out the motor and remove the headphones, 2.So that closer than 15 m children, animals, spectators and assistants do not come up, When a metal knife in the grass collided with a motionless object, a trimmer for grass or a lawn mower (motorcycle) can be strongly thrown to the side or deployed back, and maximum revolutions of a metal knife are 10,500 rpm. And he is able to cut off his arm or leg, as well as, when a trimmer is spent from under a metal knife, they can fly out and ricocheted various objects (gravel, glass, garbage).

How to mow a trimmer correctly (more about the mowing technique).

The engine revolutions when the trimmer is mowed depending on the load on the engine. the thicker the grass and, of course, is heavier than the engine, the bolder you need to open the hole (throttle in the diffusor of the carburetor). Working engine speeds during a mowing trimmer try to keep permanent (slightly higher than medium). or less gas. only depending on the overall load on the engine. No need to completely discard gas (and immediately acceleration again) with each wave of braids for grass. And the clutch is not to burn for long, and the edges on the drive shaft can overtake. and the overall wear of the trimmer for grass (motorcycles) increases dramatically.

We find out the parameters of the site before mowing with a trimmer: (to know which knives to take, how much fuel and time are needed)

How to remove a coil from a trimmer for grass and extract a fishing line for a trimmer

Initially, before filling the fishing line for the trimmer to the coil of the trimmer for the grass, 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 fishing 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 fishing 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
  • Next, from the rampart of the drum, the coil for the fishing line should be removed. It is planted on a shaft without fasteners, so it is dismantled with one hand
  • The main part of the drum is fixed using a screw, which must be twisted with a screwdriver with an appropriate tip or a bat
  • To twist it, it is necessary to hold the base of the drum with one hand, and the second to remove the screwdriver against the direction of the clockwise
  • After that, you can proceed to dismantle. To do this, you do not need to pull it with all your strength, but slightly shaking it, slowly remove it from the hook with a metal shaft on which the drum is planted
  • When installing the installation, the head should be planted in a tetrahedral slot

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 a trimmer fishing line for grass. Below the video shows a detailed process how to open a trimmer coil for grass and disassemble it.

The trimmer for the grass is very hot

Overheating of a trimmer for grass can occur for many reasons:

replacing, gearbox, patriot, trimmer, coil
  • Gasoline has not the same octane number indicated in the instructions for the unit;
  • the proportions of gasoline and oil during the preparation of the fuel mixture are not observed;
  • A mixture of fuel with butter has long been prepared (the mixture cannot be stored for more than 2 weeks);
  • The trimmer for the grass works more than the time instructions;
  • A low.power trimmer for grass on thick and hard grass is used, the device works with overload and quickly heats up;
  • shifted towards the bar or the cassette lid clutched.

The latter occurs if you install a mowing head inappropriate for this unit, or when the axis shifts inside the bar. These changes make it difficult to rotate, the load on the engine increases, and it overheating.

Typical breakdown of Patriot trimmers

According to Servy statistics, the main malfunctions when working with Patriot trimmers are:

  • The Patriot benzotrimmer does not start, there is no spark formation of the cause: the spark plug is faulty, the ignition coil (magneto), damage to the parts of the manual starter, the fuel system, wear the cylinder-piston group is faulty;
  • The gasoline trimmer for Patriot grass stalls, possible reasons: blockage of the fuel system (no fuel supply), wear of the cylinder-piston group, a carburetor, an air filter clogged;
  • The cutting nozzle of the Patriot gasoline nozzle does not rotate, the main reasons: wear of the clutch parts (fists, springs, clutch cup), wear of the drive shaft, a gearbox is defective.
  • The Patriot electric trimmer does not turn on: the power button is not good, the power cable, wear of the graphite brushes, the engine burned out (either the whole, or separately stator, rotor);
  • The Patriot electrimmer does not spin the cutting nozzle, the possible reasons: the wear of the shaft adapter (the sleeve connecting the engine shaft and the shaft of the trimmer for grass), the gearbox fails, failed the shaft of the trimmer for the grass;
  • The engine of the Patriot trimmer sparks in the engine, the main reasons: the engine completely burned out, or separately a stator or rotor burned down.
replacing, gearbox, patriot, trimmer, coil

These defects are typical of trimmers (benzos and electric fan) Patriot: some are more common, others less often. And not rarely occur due to the simplest reasons: improper operation (maintenance is not carried out), the use of non-high-quality benzo-mixture (oil and gasoline) or changes and jumps in the power of the electric network, many hours of uninterrupted operation of the trimmer for grass, mowing herbal coating not corresponding to the technical capacities of a trimmer for grass.
