Lubricant for a trimmer gearbox for grass. Than and how to lubricate?

Sometimes, in the midst of intensive spying of herbal, your trimmer for grass begins to make unpleasant, grinding sounds. This complains about the lack of lubricant gearbox. the most intensely 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 lubrication 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.

The consumption of the lubricant also depends on the temperature at which it retains its lubricant. When heating the gearbox to 40 ° C, it is believed that its working conditions are satisfactory, and there are enough 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 1.5 2 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 10 15 hours of operation of a 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.

What grease to choose

There are several ways to reduce the friction effect on the interacting elements of the angular grinder gearbox. The choice than to lubricate the friction nodes is made from the following options:

  • the use of expensive special lubricants for gearboxes from known brands;
  • the use of universal compounds suitable for any power tool;
  • lubrication of the gearbox with lithol or solidol;
  • Using self.made lubricants.

Application of special materials. the optimal solution. When choosing a lubricant for the gearbox, it is recommended to give preference to the compositions produced under the same brand as the corner grinder itself. For example, if AEG machine machine, then the lubricant must buy the same brand.

When using specialized products, the service life of the angular grinder increases significantly, since the manufacturer takes into account all the features and nuances of the operation of their own equipment. The minus of the use of branded materials is their high cost, which may affect the family budget.

Most masters use budget grinders or a Chinese.made tool. For such machines, specialized lubricants were not developed by the manufacturer and are unlikely to ever appear. However, such a technique requires maintenance. What in this case to do?

The most unfavorable solution is the use of lithola or solidol, since both of these materials are not designed to grease the friction nodes heating to high temperatures. Some owners of the Bulgarians use only these compositions, which is why their cars cannot last during the service life declared by the manufacturer. In an effort to gain profit here and now, they do not take into account future expenses for the acquisition of a new tool or replacing expensive parts.

Gear lubrication of a trimmer for grass: selection criteria

During the operation of a gasoline trimmer for grass, the gearbox begins to make rattling sounds, which are a sign of a lack of lubrication, or loss of its properties.

Of course, the owner may not attach particular importance to extraneous noises, but their ignoring will lead to jamming the gears and, as a result, the upcoming expensive repair.

Therefore, in order to avoid the prerequisites for the appearance of a rattle, it is necessary to observe the lubrication of the gearbox of the trimmer for grass, recommended by the manufacturer.

Reducer device trimmer for grass

Regardless of the manufacturer and model, the modern trimmer for grass is equipped with a gearbox for changing the angle of mechanical energy between the drive shaft and the head with a fishing line.

lubrication, mowing, gearbox, trimmer, grass

The most widespread in the benzocos were conical gears, since, unlike straight.tooth, gears with screw teeth are able to carry huge speeds, have a more smooth clutch and have increased bearing capacity.

In the duralumin case (1) there is a shaft-shuster (2) and a gear conical wheel (3), pressed on a driven shaft (4). To reduce friction forces during rotation, rolling bearings (5) are installed at the support points of the shafts.

Any gear gear is a highly loaded mechanism, whose duration and reliability of which depends primarily on the lubricant.

Therefore, in addition to the main components of the trimmer gearbox, the trimmer reducer includes a special hole, through which you can grease bearings and gears without disassembling the assembly.

Lubricant for a trimmer gearbox for grass: which one to choose?

Currently, a wide selection of plastic lubricants, which are designed to reduce friction and overheating of the rubbing parts are presented on the market for and consumables.

Therefore, every owner, when maintaining the time of maintenance, is faced with a problem than to lubricate a trimmer gearbox for grass for long.term work.

For these purposes, special plastic pastes are used, which vary in properties and manufacturer.

Lubrication for famous brands of trimmers

Each brand for the manufacture of gasoline trimmers always recommends a lubricant for the gearbox of the lawn mower of its own production.

  • Husqvarna. This Swedish manufacturer recommends using a plastic lubricant of the Multi-Purpose Grease Grasa Universal. This material is available in tubes of blue-black color with a volume of 225 or 250 grams. According to the company, this lubrication of the gearbox trimmer for the grass was designed specifically for the Husqvarna technique, taking into account the steels and speeds used.
  • Stihl. For the STIHL gas station FS, the manufacturer advises using the transmission lubricant of the Stihl Superlub FS, offered in tubes 225 grams or a one-time container of 80 grams of silver-orange.
  • Patriot. The gearboxes of the motorcycle of this brand are recommended to be served by the original Arsenal lubricant AR-417. It is specially designed for gearbox gearboxes operating at high rotation frequencies and temperatures.
  • Huter. For conical transmission of the tool models of this company Huter, you can use any of the above grades of transmission lubricants, as well as universal types of Rezoil, Cialitia and others.
  • Champion. In the operating manual, Champion Motokosovs include Champion Super-Lube EP-O. The material is supplied in a jar of 250 grams or in a disposable oil Premium Champion C1104.
  • Makita. This Japanese manufacturer advises its consumers to use the proprietary grease of Makita, which comes in white tubes with a red cover of 65 ml and 80 ml.

Factors for the choice of lubrication of the gearbox Motokosa

Often, the owner of a particular brand of gasoline trimmer for grass does not have the opportunity to purchase a lubricant recommended by the manufacturer for any reason. In such cases, a search will be required, which in its properties will be identical to a proprietary paste. Therefore, when choosing a paste for the gearbox gearbox, attention should be paid to the following factors:

  • The viscosity of the lubricant. All pastes presented on the market are divided into three main groups, namely: high.speed (contain additives), solid lubricants (softened during the operation of the unit) and universal plastic compounds.
  • The intensity of lubrication consumption. This factor is taken into account based on the personal experience of the owner, and is characterized by a period between two lubrications. Most manufacturers regulate the service of the gearbox every 20-40 hours of work.
  • The degree of adhesion to the details of the gearbox. This indicator is characterized by a clutch of plastic lubrication to the metal knot of the trimmer for grass.

How to lubricate the gearbox of a trimmer for grass

Almost every motorcosa gearbox is equipped with a small technological hole, which in the mode of operation is drowned out by a special bolt.

After thoroughly cleaning the node from the remains of grass and debris, it is necessary to unscrew the screw and enter the gearbox into the cavity of 1.5 to 3 ml of lubrication depending on the brand of the tool. For the convenience of dosage, you can use a traditional medical syringe.

During the operation, it is impossible to allow foreign particles and objects inside the gearbox, since this can lead to intensive wear of the gear gear, as well as its jamming.

Experts recommend, when completing the mowing season and long.term storage of the tool without work, to disassemble the gearbox, flushing gears and bearings, as well as re.lubricating the node.

How to disassemble, lubricate, replace or repair a trimmer gearbox for grass with your own hands

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.

How to properly lubricate the trimmer gearbox


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:

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.

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.

Most gearboxes can easily be eliminated with your own hands. Replaced details are recommended to purchase “relatives” designed for the used motorcosa.

Gear lubrication of a trimmer for grass

Lubrication of gears must be carried out regularly in accordance with the recommendations set forth in the operational instructions of the model used. You need to do this also if:

With the constant use of a trimmer for grass, its gear mechanism experiences a load from grass, dirt sticking on knives, or due to a change in torque. Lubricants must be selected high.quality to extend the service life of the gearbox.

Used types of lubrication

When choosing lubrication, it is necessary to take into account the following factors:

Famous manufacturers, for example, STIHL, Husqvarna and others, in addition to trimmers, produce lubrication for them. Such products not only reduces wear, but also protects the metal of gears from corrosion. Therefore, for motorcycle from these brands, it is better to use their lubricants.

For different models, lubrication is consumed in different ways. This is determined largely by the intensity of the use of motorcycles and heating the transmission mechanism. It is believed that the lubricant is enough if the temperature of the gearbox during operation does not exceed 40 ° C.

By consistency, lubricants for a trimmer for grass can be:

In terms of composition, the following types of lubricants are in demand:

  • graphite, significantly reducing friction, as a result of which the rotation of the gear improves;
  • lithium, which are also an excellent anti.corrosion composition, saturated with increasing the wear resistance of metal with additives without harmful substances;
  • universal, containing mineral oils and improving operational characteristics components.

Drive engines

Most mowers are equipped with a gasoline engine (ICE), it can be two.stroke and four.stroke, there is no particular difference in them. The four.stroke is more economical and powerful, but more difficult to maintain and more expensive in repair. Two.stroke is easier in maintenance, cheaper, but low.power, consumes more fuel, has a more dirty and noisy exhaust. Combined engines are also found. In addition to gasoline engines, trimmers for grass can be equipped with electric motors, which are connected by a 220V household network with a long cable, but, as a rule, these are domestic devices as they are tied with wires of power to the network.

The key to the long.term operation of any mechanism is correctly selected and high.quality oil. There are many similar products on the market, and the price is not always an indicator of quality.

It is more difficult to choose narrow oil, because it is less in demand, and sellers do not like to score them with warehouses.

After buying a trimmer for the grass, 3-speed transmission oil was purchased.

Package 100 gr. There was 250 about Bosch for this level of oil, but there was no trimmer for the grass of the right manufacturer. I had to go to the construction market and find at least a little oil for a gearbox of a trimmer for grass with a great effort.

Lubrication is made in the area.

In fact, this company is well suitable for auto.cosmetics, but I would not buy it to lubricate the equipment.

Due to the fact that the trimmer for the grass is practically not lubricated, I decided to take a chance.

By the way, this oil can be used for gear drills, that is, it can work both at high and low speeds.

You can buy high.quality oil from a well.known manufacturer.

Let’s move on to the list and use.

Having removed the protective cap, we see a cone.shaped trunk.

The opening of the tube (you will have to cut) this negatively affects the brand budget, since without additional tools we will not be able to open this tube. On more expensive models, the tube opens from the back of the cover.

By the way, each brand of trimmer for grass is focused on its own brands of oils and lubricants. This is done specifically for the sale of your products. In fact, you can take lubrices of any brand. The main thing is that they correspond to the tolerances.

He was not lazy and found the old oil from the famous brand. Here, in my opinion, this is the best option for the mechanism. In other words, even the advantage of one oil over another visually visually visible.

In the case of 3TON, something inside turned out to be something very similar to the oil “shit” with graphite interspersed. Even the smell to each other. Of course I did not spend chem. Analysis, but with a probability of 98% I can say that there is a regular oil for angular speed compounds inside the pipe.

As a result, we guarantee that we overpay even more, because the “shus” usually costs a penny.

Lubrication is convenient for pumping due to the conical shape of the nozzle.

The lubrication procedure is simple. Pour oil, turn the shaft and share it. If the gearbox is removed, the oil can get into the back. This is even good, so we push the oxygen cork out of the gearbox.

Packaging of the gearbox is also the shaft of the lubricant is missed by this grease. Water is optimal for this purpose.

12 acres of land was originally cut down. The oil in the gearbox did not proceed and remained almost at the same level. The only gearbox is noisy. Here I can’t say for sure whether it is a roofing material made of low.quality lubricants, shortcomings in the production of roofing material (new braid).

By and large, this is an ordinary “graphite”, and it makes no sense to overpay for it.

I will use it as a temporary option and will soon replace it with a decent model.

If this oil were estimated at 80, then I could advise this, but for 250 it makes no sense to buy ordinary graphite oil. Therefore, 3TON is good in the form of car care products. As for lubricants and oils, I prefer something else.

It is relatively convenient to load on a gearbox

Responsible approach to maintenance. The key to the long life of the instrument. One of the requirements in the work of Kustorez is the timely lubrication of the gearbox, as well as cleaning the filters. Each user of such an unit knows which composition to grease the gearbox. First clean in several stages, then remove the element from the body. It is cleaned with gasoline and dried. The place for the filter was prepared carefully, cleaning it of dust and old oil. The main signal of lubrication of the brush gearbox is extraneous noise and rapid heating of the equipment. This means that you need to lubricate the part as soon as possible. Lubrication intervals are indicated in the instructions for the brush. According to experts, the program should be served every 15 hours.

Time and procedure for the prevention of the gearbox.

I recommend that the prevention of a new gasoline trimmer for grass immediately after purchase, with the addition of lubrication in the gearbox. For all the high cost of garden technology, some manufacturers save and lay lubrication only at a minimum, for the duration of the

How often to lubricate the gearbox motokos.

Often, a preventive inspection of the transmission with the addition of liquid consistent lubrication is carried out once a year at the beginning or end of the season. If the gasoline trimmer for grass is used not in professional volumes, this is enough.

With large volumes of the mowing, lubricate the motorcosa gearbox every 20-50 hours of work. If the conditions of the operating mode of garden equipment are difficult, for example, a large field is pumped out at a time, and at the same time the lawn mower does not have time to cool down, or cheap lubricants are used, then the lubricant must be checked and added every 20 hours of work.

Indirect evidence that it is necessary to lubricate the gearbox to overheating or increased noise of the node. In these cases, if during the inspection it is found that the lubricants in the node are enough by volume, then I recommend that it replace it, while it is advisable to choose another car chemical manufacturer. I also recommend a complete replacement of lubrication, with disassembly and flushing of the node, when buying a used gasoline trimmer for grass.

Lubrication for gearbox of gasoline trimmer for grass.

Assortment of lubricants for garden technology

According to the instructions for lubricating the conical gearbox, a special transmission liquid consistent grease should be used. As a rule, manufacturers of garden equipment produce and recommend the chemistry of their brand as the most adapted to their devices.

At the same time, to reduce the cost of the operation of garden equipment and increase the attractiveness of a brand of auto chemistry, grease for garden equipment usually produces multifunctional. It is intended not only for lubricating gearboxes of gasoline trimmers, but also for processing hoses, transmissions and gearboxes of any garden equipment and mechanical devices operating under high loads.

Even if a specialized lubricant for the gearbox was almost completely developed during operation, the additives still create an effective lubricating protective film on the surface of the gears.

lubrication, mowing, gearbox, trimmer, grass

It should be noted that many owners of the motorcycle in the vast CIS for lubrication of the gearbox use ordinary litol-24 or lubricant for Circus on a lithium basis. It is convenient to refuel the gearbox using a 5-cc medical syringe. Many motorists, instead of a side screw, pick up a carvings and screw a tavniper from passenger cars that have served their crosses. This refinement allows the addition of a lithol without disassembling the node using a syringe for consistent lubrication.

A undoubted plus of the use of lithola and lithium.based lubricant for refueling the transmission of motorcycles is a reduction in operation. But there are nuances because of which spears are breaking on the forums of the Internet gardeners. My thoughts on the topic, what can be lubricated with lubric.based lubricants, and what is not read in the article “Litol as lubrication of the motorcosa gearbox”.

How to lubricate the motorcosa gearbox, gasoline trimmer for grass.

Side Bolt on 17 on the gearbox of a gasoline trimmer for grass

In order to avoid random launch, all preventive work on a motorcycle is necessarily carried out with a removed electric cap / plug from a candle. Do not turn the trimmer for the grass to avoid gas leakage.

We unscrew the side screw on the motorcosa gearbox. Depending on the company.manufacturer of a garden tool, instead of a screw for a hexagon, there may be a turnkey bolt, more often at 17. The thread is ordinary, unscrew counterclockwise. Do not lose the sealing puck.

If the lubricant is not visible on the internal end part of the screw, then it is necessary to add 3. 4 grams. Scroll through the gear with your hand, changing the direction of rotation so that the lubricant is distributed through the gears. Repeat the operation several times. On average, about 5. 10 g enters the gearbox. The node should be completely filled with grease, taking into account the installation of the screw. Then set the screw in place, tightly tightening it.

Reducer device trimmer for grass

Regardless of the manufacturer and model, the modern trimmer for grass is equipped with a gearbox for changing the angle of mechanical energy between the drive shaft and the head with a fishing line. The most widespread in the benzocos were conical gears, since, unlike straight.tooth, gears with screw teeth are able to carry huge speeds, have a more smooth clutch and have increased bearing capacity.

In the duralumin case (1) there is a shaft-shuster (2) and a gear conical wheel (3), pressed on a driven shaft (4). To reduce friction forces during rotation, rolling bearings (5) are installed at the support points of the shafts. Any gear gear is a highly loaded mechanism, whose duration and reliability of which depends primarily on the lubricant. Therefore, in addition to the main components of the trimmer gearbox, the trimmer reducer includes a special hole, through which you can grease bearings and gears without disassembling the assembly.

Prevention and possible malfunctions of the gearbox

The lawn mower requires the first prevention immediately after the purchase, because the manufacturer lays a small amount of grease. If a trimmer for grass performs a small amount of work, then lubricate the device at the beginning and at the end of the season. If the lawn mower works a lot, then we lubricate after 30-55 hours of operation.

The main faults include the most common options.

  • Strong heating. This suggests that the lubricant has ended. It is necessary to add lubricating materials and run them in weak mode.
  • Gearbox vibrates or stagger. This situation indicates mechanical damage.
  • There is a knock. Then the bearing collapsed, the boot was damaged.
  • If the knife of the trimmer for the grass is jammed, then the mechanism should be changed completely.

Lubrication of the shaft and gearbox of the lawn mower, trimmer for grass

Dismantling of the rod of a lawn mower, a trimmer for grass for lubricating the shaft and gearbox on the example of the PRORAB-8406 motorcycles. Removing a shaft from the bar differs from some videos.

Basis shafts (gasoline trimmers) rotate in sliding bearings, put into the bar. The lubricant applied to the shaft penetrates the scurry of the shaft with bearings, thereby reducing the friction force, slowing down the wear of the parts and increasing the service life of the motorcycle. And as a bonus: a decrease in vibration and noise, a slight increase in the power of the tool.

Removing and lubrication of the upper shaft of a trimmer for grass

First of all, we remove the lower part of the rod from the connecting coupling, and then disconnect the coupling from the upper part of the bar (here we are talking about a coupling connecting two halves of the bar).

Trimmer for PRorab-8406 grass with a detachable coupling and the lower part of the bar

Now the most interesting thing: on some videos, as on this, holding the ticks of the shaft with ticks, sticking out of the upper part of the bar from below, knock out it with blows on the rods from the rod along with the rolling bearing (here we are talking about the coupling connecting the upper and lower shafts). Some have a gas station with a collapsible bar, as in the video, a coupling connecting the upper and lower shafts, it is put into the rolling bearing.

With our trimmer Prorab-8406 and such a number will not pass like him. They do not have a rolling bearing, and the connecting coupling (sleeve) is a continuation of the shaft of the upper rod. A locking ring is installed in the upper part of this shaft, which must first be removed.

The place of fastening of the upper part of the bar to the clutch clutch body

  • We turn off the central screw completely. It fixes the upper part of the bar, partially entering the hole drilled in it. We loosen the side clamping screws and remove the bar from the clutch clutch body.
  • We put out the shaft from the upper part of the bar on ourselves how much the backlash allows to get to the stop ring and remove it. A special puller may be needed. We extract a locking ring.

Stop ring on the upper shaft Motokos

  • Without a locking ring, the upper shaft is easily extracted from the bar from the opposite side. Lubricate it, not forgetting about the slots in the bushings (couplings) on the shaft of the bar and on the clutch shaft.
  • The greased shaft is installed in place in the upper part of the rod and fixed with the locking ring. We insert the bar into the hole of the clutch clutch cover and combine the hole on the bar with the threaded opening of the fixing screw.
  • We screw the fixing screw and fix the upper part of the trimmer rod for the grass with side screws in the clutch lid.
  • Clean the connecting coupling of the bar from the garbage and install from below on the upper part of the bar.

I don’t have a puller, and I use two large stationery paper clips to extract a locking ring. Previously, they need to be straightened, on one side make a half.ring for the fingers, and on the other. bend small hooks.

We capture holes in the locking ring and try to push them apart. With difficulty, but it turns out, and the ring is afraid of. If you know another way to remove a locking ring without a puller, share in the Комментарии и мнения владельцев.

In many videos, masters recommend using Shrus-4 grease, this is the best option. In its absence, to lubricate the shaft of the gas mowing rod, you can use Litol-24, which is focused on temperatures up to 130 ° C. But solidol, with the worst lubricants and working at temperatures up to 70 ° C, is not recommended to use.

However, if you urgently need to lubricate the shaft of the rod motorcosa, but there are no suitable materials, then solidol or even ordinary motor oil will be better than nothing at all.

Removing and lubrication of the lower shaft of the lawn mower

To extract the shaft from the bottom of the bar, we initially remove the coil gearbox.

  • We unscrew the completely central fixing screw. On the back of the lower clamping screw, we turn the nut and unscrew the screw completely to disconnect the coil gearbox from the protective casing.
  • Weaken the upper clamping screw and remove the lower part of the bar from the coil gearbox body. We take out the lower shaft from the bar from the gearbox side.
  • Clean the shaft of pollution and grease it with SHRUS-4 or Litol-24, not forgetting to clean and lubricate the coupling (sleeve) with slots in the gearbox.
  • We install the shaft in the bar, and the bar in the lower gearbox of the lawn mower and combine the hole on the bar with the hole for the central screw. We screw the central screw. Next, wrap the lower screw, clamp the lower part of the bar in the gearbox body with the upper and lower screws and tighten the nut on the back of the lower screw.
  • Add 20-30 ml of lubrication to the coil gearbox through a hole closed by a screw located in the photo on the right.

Lubrication of the lower gearbox Motokos

The coil gearbox is recommended to lubricate every 10 hours of work. The best lubricant for him, as well as for the shaft of motorcycles, “shus-4” or “litol-24”, designed to work at high temperatures.

To add lubrication to the lower gearbox, we use a disposable medical syringe with a capacity of 5 or 10 ml without a needle:

  • We remove the piston from the syringe and disconnect the needle if it was attached.
  • Add to the syringe from the piston side the required amount of thick lubricant “shus-4” or “lititol-24”.
  • We insert the piston into the syringe and shift the lubricant to the output (drive air).
  • The tip of the syringe without a needle is inserted into the lubricant hole and squeeze out the lubricant into the gearbox.

In my guide of the user’s user trimmer for gasoline grass PRORAB 8402R, 8403R, 8405R, 8406R it says that the use of motor oil for two-stroke engines in the amount of 20-30 ml is allowed as a lubricant for the gearbox. But this is not the best option, since the gearbox does not have sealing oil seals and motor oil flows faster than thick lubricants.

Many Trimmeres users do not pay much attention to servicing their tools. In particular, this applies to such a node of motorcycles as a gearbox. The work of the gearbox is associated with heating.

With prolonged operation, motorcycles occur regular overheating of the gearbox, which leads to its breakdowns. Reducer breakdown leads to the fact that the tool is unsuitable for operation and it must be repaired.

Reducer repair is an expensive event, so it is recommended not to bring the tool to such a state. The main reason for overheating of the gearbox and its failure is the absence of lubrication in it.

The article tells how to properly lubricate the gearbox of a trimmer for grass to avoid its breakdowns.

The frequency of reducer service

Lubricating the gearbox is recommended in two cases:

Necessary tools and materials

The following tools and materials will be needed for the maintenance of the gearbox:

Hexagonal key for opening the reducer lubricant hole

Usually, such a key is included with a motorcycle or trimmer.

The next tool is a regular medical syringe with a volume of 10 ml. It is with the help of a syringe that the lubricant enters the gearbox.

It is recommended to use proprietary lubrication from the manufacturer Motokos. In extreme cases, you can use any lubricant to lubricate rotating mechanisms, for example, Litol 24.

We open the gearbox

In order to gain access to the gearbox, it should be opened. To do this is quite simple. you need to unscrew the gearbox with a hexagonal key. This bolt for all Motokos is in the same place. directly near the working body.

Spring refueling action

The diameter of the tube with grease does not correspond to the diameter of the gearbox

In order to easily make lubrication into the gearbox, it is necessary to use the syringe.

Then a syringe is filled with a tube of a tube.

After which the piston is again inserted into the syringe. The syringe is ready to refuel the lubricant in the gearbox.


The syringe is inserted into the gearbox hole

First, the syringe is inserted into the gearbox hole.

Squeezing in the gearbox slightly lubricant and turning it for about a quarter turnover

Then you need to squeeze a little grease in the gearbox and turn it for about a quarter of turn.

When all the lubricant is squeezed out, the process can be considered complete

Lubrication is seasoned in small portions. After each supply of lubrication, the gearbox turns on 1/3. 1/4 turnover. It is advisable to choose the amount of lubrication for each refueling so that the gearbox during the lubricant makes a full revolution.

Activation of the gearbox

After the gearbox is filled with lubrication, twist the gearbox and it is well clamped.

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, having 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 of a starter coil, since 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.
  • 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.


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.
