Lubricant for a trimmer gearbox for grass

Buying any equipment in its kind is a lottery, but much also depends on the gardener. In caring hands and Chinese samples serve for a long time and do not let their owners at the wrong time. And if you forget to lubricate the motorcosa gearbox in time, do not clean filters, use cheap low.Quality gasoline, then garden equipment from the most eminent brands will be a headache.

Lubrication of the gearbox Motokos is one of the most important elements of maintenance of a gasoline trimmer for grass, which the user should be carried out directly.

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 run.In.

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.

I also recommend a complete replacement of lubrication, with disassembly and flushing of the node, when buying a used 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.

Such lubricant for the gearbox is sold in the tubes convenient for use and subsequent storage.

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.

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.

A undoubted plus of the use of lithola and lithium.Based lubricant for refueling the transmission of motorcycles is a reducing 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 that 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.

Then set the screw in place, tightly tightening it.

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 a lubricant for a shred or lititol-24, not forgetting to clean and grease 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.

In the instructions for the operation of a trimmer for grass gasoline PRorab 8405m, 8406M, it is recommended to lubricate the gearbox with solidol or its analogues, in extreme cases pour liquid engine oil. Excess oil will flow out, since the gearbox does not have sealing oil seals.

In the 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 is allowed as a lubricant for the gearbox. There are no mention of solidol and his analogues.

In order not to bother, lubricate the lower gearbox with your lawn mower with the same grease as the shaft of the bar or fill the engine oil.

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.

When lubricating, special attention is paid to the following elements:

  • Flywheel: on its surface, as a rule, intensively sticks the remnants of grass, and thickening herbal juice creates additional resistance.
  • Dog of a starter coil, which in the process of turning on the drive is constantly in contact with the grooves on the flywheel. At the same time, not only mechanical wear occurs, but also the mechanochemical corrosion of the Makhovik-Sobachka compound, since the materials of this pair are different (the flywheel is aluminum, and the dog is steel).
  • Bearings, if their seals are worn out, and through them the remaining lubricants are squeezed out. In this case, the unit begins to vibrate intensively when loading. This happens with trimmers of Chinese.Made, so it is worthwhile to think about replacing a bearing unit with a better, for example, from the Swedish company SKF.

Ensuring the desired equipment care allows lubricants for reducers of trimmers, the types of which depend on their mixture:

For semi.Liquid lubricants typical, the presence of colloidal allowing accounting (software) with M of various additives and additives. Plastic lubricant is suitable for a screw.Shaped and gear gear, because it is a universal option. The initial state of rigid suspensions is plastic.

Lubrication of the reducer of the lawn mower is provided with a special composition for gearboxes. Most of the lubricants have the form of semi.Liquid systems. When selecting the desired lubricant, it is required to take into account the temperature regime, which is intended for the mixture.

A trimmer for grass on gasoline can work excellently in any weather. Electronic models of benzos are not able to satisfy the requirements of the owners of personal plots in this matter. Gasoline trimmers are characterized by high power, which is associated with the possibility of processing huge areas. Devices on gasoline with also become unusable, which is produced for various reasons. In most cases, due to errors for servicing the device.

For gasoline trimmers, an important condition for the repeated cleaning of the fuel tank and the change of oils. In order to increase the service life of an electronic trimmer for the grass, constant maintenance of different parts of the mechanism is carried out

Care for equipment elements should not take solid volumes of time, since it consists in the procedure for lubricating the rubbing parts before cleaning the filter.

In the production of trimmer lubrication, special substances are used that meet environmental norms. After use, they are able to break up in the environment without harming. Since the mixture of the composition has an overstated level, when heated, the lubricant in the density is reduced. This provides reliable protection of parts in the circumstances of the highest temperatures.

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:

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.

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.

How to grease a STIHL gearbox

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 high.Degree mineral oils and improving operational characteristics components.

An example of suitable lubricants are: Champion EP-0, Gear Grease Oregon, Oleo-Mas, Azmol 158, Litol.24

You should also pay attention to the advice of manufacturers on this issue and use the materials they offer. You can buy them at specialized retail outlets. A lubricant Champion EP-0 Universal 120 gr

How to disassemble and assemble a trimmer for grass

For an independent disassembly of a trimmer for grass, a set of tools is prepared:

Disassemble each node of the device separately for diagnostics.

Dismantling the electrimmer

Electric trimmer for grass consists of a main electric block and a rod. Consider how to analyze for the repair of the electric part:

  • Put an electric car on a flat surface.
  • Unscrew the fixing screws of the trimmer body for grass on one side.
  • Having removed the lid, you can diagnose, repair or replace the electric motor, drive and bearings, brush unit, launch buttons and other elements.
  • To assemble a trimmer ectric for the grass should be sequentially: first, install the motor by tightening the fasteners; connect an electric circuit; Gently lay the wires in the case in the corresponding recesses; Close the top cover and tighten the screws.

Dismantling of a benzotrimmer (the video instructions shows a trimmer for Gruntek BS 52x grass) for engine repair is performed as follows:

  • First you need to remove the gasoline engine from the rod.
  • Disconnect the starter by unscrewing the fixing bolts.
  • Remove the protective casing of the gas tank, and the tank itself.
  • Unscrew the spark plug and remove the outer engine cover.
  • Remove the carburetor, pipe, ignition and muffler from the engine.
  • In order to conduct diagnostics and replace faulty parts of the motor, first of all it is necessary to disconnect the clutch node. To do this, fix the combustion chamber, and with the help of a unit key, unscrew the fixing bolts of clutch.
  • After the repair, collect a motorcycle, performing the same action in the reverse order.

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.

How to service trimmer head, how to lubricated trimmer head to prevent wear and damage

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.

Varieties of lubricants

To care for the units of the mechanism, lubricants of different consistency are used:

lubricate, shaft, lawn, mower, strong
  • Semi.Liquid. Such compositions contain a variety of additives and additives.
  • Plastic. Are the most universal option. Most often used for gear and screw gears.
  • Solid. Plate suspensions in its original state.

A special gear composition belongs to the semi.Liquid system.

Popular is a grease for a trimmer for the grass “Stihl”. Thanks to the special composition and components, wear is significantly reduced and resistance to corrosion increases. The main properties of the lubrication of this brand are:
