Reducer of a trimmer for grass. lubrication and elimination of malfunctions
Regularly using motorcycles, its owner may notice an increase in the temperature of the gearbox or the emergence of new uncharacteristic sounds in it, which were not previously heard. These signs report that the mechanism requires lubrication. If you ignore them, after a while new, more significant problems will appear. So, without lubrication of the gear, they wear out much faster and soon require replacement. In some cases, the part jams when working. It should be understood that the damaged transmission mechanism can cause damage to other details of the structure. Make a repair of a trimmer gearbox for grass, as well as lubricating the part is quite feasible with your own hands if you know how such procedures are performed correctly, as well as have the desired tool and materials.
Reducer is a device for transmitting rotation to the cutting part from the engine shaft. Its second purpose is to convert the angular speed of rotation of the output shaft into lower or higher speeds. In the first case, the device is called a “demultipliter” and is used on trimmers with powerful engines, in the second. “multiplier” and installed on low.power tools. The gearbox is always placed in the lower part of the rod of gasoline and electric brands of different brands, whether it be “champion”, Huter or other brand.
The reducer device looks as follows. The main details are the shaft-sheet (for transmitting movement from the motor) and the gear installed on the driven shaft (to rotate the cutting unit). To reduce friction during movement, rolling bearings are placed on the support points of the shafts. They are protected by special washers, allowing to preserve the lubricant and prevent the penetration of dirt inside the seat. All parts are placed in a duralumin case with a special technological hole for entering lubrication. It is necessary so that you do not have to constantly disassemble the knot to make lubrication.
Thus, in the design of the gearbox, depending on the model and brand that released the technique (for example, Sterwins, “foremen”), it includes several gears that are linked to the teeth for transmitting rotation and moving at high speed. Due to significant friction, they are strongly warming up.
Important! In the absence or lack of lubrication, gear overheating occurs, followed by their breakdown, after which it becomes necessary to replace damaged elements. To avoid such unpleasant consequences, it is necessary to use the lubricant in time and treat it with a gear node.
Features of different types of gearboxes
Electro and benzos manufacturers install various models of gearboxes on their equipment. Usually they differ from each other in the shape and dimensions of the seat, which is performed in the form of a circle (popular diameter. 24, 25.5 and 26mm), square or sprocket.
Another difference between the gearboxes of Chinese and European brands are types of transmissions. They are conical, worm, spiroid, combined, wave, planetary, cylindrical. Typically, worm gearboxes are used on benzocoses.
How a gearbox is arranged in a benzokos
Reducer of the lawn mower. transmitting an element of movement by rotation of the shaft in the engine, which supplies this rotation to the knife. This node is located below, on the bar of a trimmer for grass. To reduce speed, this device is also necessary in a gas station.
In accordance with various brands, this device consists of elements such as gears, in different quantities. Their rotation occurs quickly enough. Therefore, severe friction creates excessive overheating, and as a result, it is necessary to do a difficult repair. The details also heat up and fail the absence or small number of lubricants. Get worried about the timely maintenance of the transfer node, avoiding premature breakdown.
Modern manufacturers produce benzo.codes that differ in the seat:
The most popular sizes of the seat of a round silhouette are from 24 mm to 26 mm.
There are also various types in motorcycles. There are many of them: conical, worm, spiroid, cylindrical, planetary, wave, and various combined.
Nodes as part of a lawn mower, which most powerfully suffer a strong load, are a gearbox and a drive shaft. Because of this, these details often break, fail. Between the translated shaft and the gearbox, the movement is carried out due to the adhesion in the teeth of the six. They are installed in different angles in relation to each other. Drawing transmission is effective only when there is no mechanical damage. The mechanism can also be closed when the device is subject to overheating.
What breakdowns are in the gearbox, how to eliminate them
Consider which culprits of the breakdown are possible, and try to remove them.
The transfer node often overheats. The reason for the problem may be the use of poor.quality lubricant material purchased in unverified stores or in spontaneous markets. Perhaps the lack of lubrication is possible. The solution in this case is to apply a quality product and carefully lubricate all surfaces.
Also, overheating of this node is possible due to the installation of new gears that should be worn out. To fix this problem, work with the tool not too actively, do not overload the braid, make frequent breaks to cool down the device.
Когда вал вращается – появляется люфт и стук, вал стопорится или заклинивается. This definitely means that some kind of bearing has worn out, it is required to replace it with a new.
The transmission mechanism is kept unstable or even flies out of the bar. it has a damaged case, it is necessary to make a complete replacement. Sometimes, if the damage is not too significant, you can connect this place and a break about the help of a metal clamp.
The gearbox is not fixed with the pipe. So, the place on which the gearbox is attached is worn out. You can make a replacement of the bar, or just wrap it with insulating tape where you see the mount.
The shaft and the knife does not spin, or begins movement, and then with an increase in the load, the shaft stops. This indicates that the gear teeth are broken or worn out. In this case, replace the spoiled details.
How to disassemble a gearbox on a trimmer
It is believed that there is no universal lubricant for a trimmer gearbox for grass, but this is not exactly. In fact, a suitable lubricant will be the one in which the subsequent components are located:
From time to time, in the midst of saturated work on mowing the grass, your trimmer for grass begins to make nasty, grinding sounds. This complains the gearbox on the lack of lubrication. a more actively loaded node of the device. And soon, these “warnings” may follow the junction of the drive
What lubricant should be used for a trimmer gearbox for grass?
In the process of work, the mechanical part of the trimmer for grass is loaded with contact efforts on the teeth, resistance reactions from adhering grass (sometimes with dirt), dynamic, shock loads due to a constantly changing torque. The lubricant for the gearbox of the trimmer for the grass should fully consider these features, so the selection of the brand should be strictly individual.
The following factors are taken into account:
- Manufacturer’s brand. Each trademark is not unreasonably focused on lubricants of its own manufacture (you can talk about cheap Chinese products later). This applies to manufacturers such as Husqvarna, Stihl, Huter, Makita, etc. The exception is trimmers for domestic grass: for example, the caliber in the user’s instructions does not indicate a lubricant brand at all
- Break of lubrication. As you know, all lubricants are divided into three groups. high.speed (colloidal systems containing various additives), plastic compounds of universal use and hard lubricants softening during operation.
- Good adhesion to the surface of the parts of the gearbox, as a result of which the lubricant is not squeezed into the gaps or outside the node.
- The intensity of lubrication consumption by the gearbox. Here you have to focus on their own experience and recommendations of specialists, since some manufacturers of trimmers, hoping for their own service centers, do not give clear recommendations at all regarding the period of the reducer between two lubricants.

It is believed that there is no universal lubricant for the gearbox for grass, but this is not entirely. In fact, a suitable lubricant will be the one in which the following components are present:
- Anti.sympathetic supplements, which include toxic lead;
- Solid lubricants with the presence of graphite or disulfide of molybdenum (the latter is preferable, since the lubricant is completely preserved for the large range of the speed of the shaft);
- Only mineral (inorganic!) oils, with a high degree of cleaning.
The mentioned requirements are fully met by Gear Grease Oregon or Champion EP-0, domestic compositions Oleo-Mas, Litol.24, or Ammol 158, as well as those recommended by the manufacturer of a particular model of a trimmer for grass.
How to lubricate the gearbox of a trimmer for grass?
In the upper part of the case, where the gear unit is installed, there is a technological hole that, when operating the trimmer for the grass, is drowned out with a screw. This screw is twisted, and 1.52 ml of grease is introduced into the hole using a nose available on a tube. If the lubricant was purchased in another packaging, then a regular disposable medical syringe is suitable for this operation.
After that, the screw is installed in its former place. This procedure, regardless of the user’s recommendations, should be performed every 1015 hours of operation of the trimmer for grass in working mode. Other reasons for updating or replacing the reducer lubrication are the independent performing of small regulatory work (for example, cleaning and washing the gear of the gearbox before the start of the summer season), repair of the node, preserving the trimmer for grass for the winter period, etc. D.
If the reducer node is disassembled, it is recommended to completely remove the remaining lubricants from the surface of the parts, even if it does not have traces of oxidation and pollution. And only then apply a new grease. After applying the lubricant, it is recommended to handle the shaft several times manually, and make sure that the grease is evenly distributed over all the details of the gearbox.

The main malfunctions of the gearbox and ways to eliminate them
With a gearbox of an electric or gasoline trimmer for grass, various breakdowns occur. The most frequent of them are presented in the table further. There you can also find the reasons for their occurrence and methods of elimination.
| Reducer malfunction | Possible causes of breakdown | The method of elimination |
| The gear node is heavily warmed up | the use of unsuitable (low.quality) lubrication or its absence | you need to replace or add lubricants |
| The gears are new and did not get sick | It should be worked for a short time for a time without strong loads with regular stops so that the mechanism manages to cool | |
| shaking of the shaft during rotation, the appearance of backlash and knocking | destruction or significant wear of any of the bearings | replace the failed bearing with a new |
| The transmission mechanism flies from the rod of motorcycles or stagger | Damage to its body | It is necessary to replace the part |
| In some cases, with minor damage, a clamp made of metal, a place with a fault is carried out | ||
| not fixed on the pipe | wear of the docking area | you can make a winding from the insulating tape at the mounting site or change the bar |
| The output shaft with a knife does not rotate or stops in case of an increase in the load | wear of the teeth on the gears or one of them | It is required to replace the interacting pair of worn details |
Bearings are destroyed due to the use of inappropriate lubrication or due to its absence. Their damage is also caused by severe operating conditions of motorcycles and the ingress of extraneous particles of the material (for example, broken metal teeth of mechanical transmissions) due to the fact that the integrity of the anthers is violated.
To remove the bearing, you need to disassemble the gearbox and use a special puller. If it is not, then you can try to do it with a hammer with a mentor. In this case, work should be carefully so as not to damage the seat. Using the pre.heating method to shoot the bearing is not recommended. This is due to the fact that the metal may lose the required operational characteristics.
If the knife ceases to rotate under load or stands still, then this is accompanied by an uncharacteristic sound.
Most gearboxes can easily be eliminated with your own hands. Replaced details are recommended to purchase “relatives” designed for the used motorcosa.
Rod and the drive of the working body
The bar has two very important functions: the first. forms a hard frame of the entire structure, the second. a shaft passes inside the metal roller rod, which connects the working organ with the engine. By the appearance of the rod, you can determine the class of the tool, if the bar is curved. this is convenient for work, but in this case the drive is a flexible shaft, which cannot convey a large torque. If the bar is straight, a hard metal rod passes inside, it can transmit more reliably and torque. Therefore, a professional tool always has straight rods.
Repair and lubrication of a trimmer gearbox for grass
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.
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:
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.

Law out.handies malfunctions and ways to eliminate them
At least what type of benzos has a half bar, in which the binding cable between the motor shaft and the lower gearbox is placed, which transfers rotation to the tool with cutting inventory. In the highest part there is a carburetor and a motor, a gearbox and a working tool closed by a casing are placed on the bottom. In the middle part there is a transverse handle when the control buttons are placed. To unload the hands, there is an unloading belt holding the bar with a torso of the operator.
In the process of choosing a lawn mower, a device with a two.stroke engine is better than a four.stroke. Two.stroke engine is more maneuverable and easier to repair. With a four.stroke node below the level of vibration.
This follows, repair of the lawn mower is to eliminate defects;
For now, eliminate the malfunction, it is necessary to diagnose, find a non.working node.
Know the point of lubrication of the tool in principle. Unchanged care, cleaning the device after work will allow you to extend its service life. Before starting work, you need to tighten the fasteners, cook fuel and season the tank.
Electric trimmer for grass vibrates
Many mowing users noticed that some time after the start of the apparatus, it begins to vibrate very much. On some trimmers, mainly in models more expensive, an anti.vibration system was installed in the form of shock absorbers seized between the engine and the bar. But in some cases, even she does not save from strong vibration. The reason that strong vibration appears in the trimmer, there may be a small amount or complete absence of lubrication on a hard or flexible shaft located inside the rod of the apparatus.
Replacing the lubrication of the hard shaft is as follows:
The lubrication of the flexible shaft is as follows:
This is done like this: first you need to lubricate the end of the cable, and then insert it into the bar, after which, as it moves into the pipe, you should apply grease to the part and evenly distribute it on the surface. Then insert a bar with a flexible shaft into an electric engine and fix it.
In the event that the lubricant did not help, and the vibration continues to appear, you will need to change the flexible shaft.
How to lubricate a trimmer gearbox for grass / Gearbox gearbox / Reducer Motokosa
Lubricate the trimmer gearbox for the grass at least once a year, but it is better to check the lubricant after every 20-25 hours of operation or when the gear noise in the gearbox Motokosa appears. How to lubricate the gearbox gearboxes. For lubrication, first you need to clean the cork itself and the place around the cork and the remnants of the grass so that they do not get inside the gearbox when filling it with grease. Then it is necessary to unscrew the plug for lubrication of the gearbox (for example, the Echo lawn mower is “17”, in Husqvarna-a 6-garnet on “5”, for Chinese lawn mower-the key on “12”). It is better to use the same manufacturer as your trimmer for grass or just from world-famous brands, such as Oleo-Mac, Stihl, Husqvarna, Oregon, Liquimoly, Litol-24, Azmol 158 and T.D., If only it was not a fake! The tube, if new, print, removing with your fingers a cork or piercing the back of the lid with a jumper in the nose of the tube. Then we put a trimmer for the grass on the left side, and rotating the knife with one hand (so that the gears are smashed and filled with the entire volume), squeeze out the lubricant from the tube with the second hand through the hole inside the gearbox until it is completely filled. Then we tighten and clamp the trimmer gearbox for the grass and the tube plug with grease. If the lubricant is not in the tube (and, for example, in the bank), take a medical syringe without a needle, take out the piston, fill the lubricant (with your finger) in the syringe, and then fill the trimmer gearbox from the syringe with a syringe.
Modern technologies and technology allow you to produce the best and optimal technical solutions that become effective assistants when arranging a summer cottage or personal plot. Green lawn and other stands can grow rapidly, to put the house mowl is used to put in order and haircuts of lawns, which is differently called a motorcycle or a trimmer, a benzo-core.
Traditional braids for grass are inconvenient and unsafe in use, require significant expenditures and their own forces that will help to save law mowers that combine functionality and practicality in their design. In the photo Benzosos, you can see various high.tech devices that have a complex of operational characteristics, including parameters such as increased performance and long service life.
A convenient and reliable trimmer for grass is a technical device consisting of individual mechanisms, details and elements that can be worn out, become unusable and damaged during intensive operation.

Asseting device and common malfunctions
The easiest way to give the lawn mower for repairs, allocating a certain amount of funds from the family budget, operational and high.quality repair with your own hands is no less simple and convenient to understand the design of the lawn mower and fix all the problems.
The massive and piece manufacture of trimmers is based on the use of generally accepted technology, the typical design scheme consists of certain elements and parts, it is important to know them when carrying out independent repair work:
Device, functions
The motorcosa gearbox transfers torque from the motor to the working (cutting) parts of the device.
This function is provided by the internal structure of the gearbox, which is a system of gears that lower or increase the speed of rotation of parts.
Gearboxes used for personal plots are:
This classification is based on the type of traction characteristic, namely the mechanical transmission of torque.
The gearboxes also differ in the form and dimensions of the landing hole: it can be square, round or starry. Of course, the most common gearboxes with a round landing place. At the location, the gearbox can be lower or upper.
For the normal operation of the mechanism, the lack of mechanical damage to the parts of the gearbox and maintaining a certain temperature regime is necessary. Any cracks, chips and overheating will lead to a malfunction and stopping of the lawn mower/trimmer for grass, which, in turn, will require the renovation of the gearbox. Regular lubrication of the mechanism can significantly reduce the risk of such problems and increase the life of a trimmer for grass.
Possible problems
There are several common malfunctions that are subject to the gearbox of the lawn mower.
Performance
The choice of a benzocosille, or they are also called by the name of the cutting device. trimmers for grass, should be made from the volume of work, the more processed area, the more power is needed. For small plots, household are chosen, trimmers for middle.class grass are suitable for garden areas, for pumping a large area, especially if there are weeds or shrub thickets, a powerful professional tool is needed. park. Such a technique has an engine power of more than 2.5 liters.With. And it can work 3-4 hours a day.
The trimmer gearbox for grass includes 2 shafts. the first has a drive from the engine, and the other is used to rotate the cutting blade Motokos or Electimimer fishing line. Conical gears are made as a whole with a shaft, but there are versions with the installation of a separate part on the slotted connection. Models with different angles of the location of the teeth are available, which depends on the layout of the tool. There are modifications of gearboxes with worm, planetary or mixed (multi.stage) gears.
Shafts are installed on rolling bearings, which are closed with protective washers. Details ensure the preservation of lubricant and prevent dirt from getting on the workplace. The bearings are installed in the gearbox body made of aluminum alloy. The unit unit, consists of 2 symmetrical halves, which are interconnected by screws. To ensure the tightness of the joint, a separate gasket or sealant is used.
The lower gearbox for a trimmer for grass is installed on the tool through the planting nest. There are several varieties of the joint that differ in shape.
The most widespread are round seats with a diameter of 24 or 26 mm.
There are modifications of the tool with a square or multifaceted joint of elements. The transmission of torque is carried out through the slotting connection.
User reviews about lubricants
Experts advise using only original materials, the characteristics of which meet the requirements of the manufacturer. If there are no one, you should clarify how to lubricate the gearbox of the trimmer for the grass. Experienced users do not advise using solidol, because this material is not suitable for the temperature and speed characteristics of the node, as well as in consistency. Also, the above material does not have anti.intelligence properties.
The range of operating temperatures of the solidol is from minus 40 to 65 degrees, but even with such parameters in the process of heating, the density of the material increases, and the lubricant itself becomes rough. With emergency need to process the tool, you can use Litol-24.
