Lubrication of the gearbox Motokosa how often. How to lubricate the gearbox of a trimmer for grass?

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 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.

Then set the screw in place, tightly tightening it.

Control of the correctness of lubrication in the gearbox angular grinder

The last step during the maintenance of an angle grinding machine is to check the correctness of the application and distribution inside the gearbox of the lubricant. For this, after the gearbox is assembled, the power tool is included without load for several minutes, while there should be no extraneous sounds, smell and other things. If they occur, it is necessary to immediately turn off the angular grinder from the network. The heating of the gear unit is also checked. The lubricant should distribute heat evenly and the temperature of the gearbox should not be very high.

After short work, 4 screws are unscrewed, then remove the lid from the gearbox. Visually, the braid gears should be examined for their lubricants. If it is absent, then too small the amount of lubricant was laid and should be reported. If in the process of work it is squeezed out of the cracks, then it means it was laid much and excess should be removed. After making any changes, again check the operation of the corner grinder without load.

Device and principle of operation of the trimmer gearbox

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.

Prevention of breakdowns

To avoid breakdowns and subsequent expensive repairs, it is recommended to comply with a number of simple rules for the operation of a trimmer for grass and servicing the gearbox.

• Lubricate this garden tool immediately after purchasing. before starting operation. Usually or huter) applies only a small amount of lubricant, which is enough only for running.
• At the end of the season or before a long.term storage of a trimmer for the grass, you should disassemble the gearbox, check the condition of the bearings and gears, grease the knot.
• It is required to add grease after the tool works from twenty to forty hours. With intensive loads, this time is reduced to twenty hours.
• Change grease to a new one is necessary when repairing a structure or before the start of the season.
• Когда редуктор перегревается или издает сильный шум, нужно проверить наличие смазки. If it is present in sufficient quantities, it is recommended to replace it completely with another.

So, you can carry out repair and lubrication of the gearbox Motokosa yourself at home. The addition of lubricants will not be difficult, a detailed description of this process and recommendations for the choice of a suitable substance can be found in the instrument operation instructions or on the video, which many are presented on the Internet. Most of the breakdowns of gearboxes are typical for trimmers of different brands, it is quite easy to eliminate them if you know the correct procedure for actions. And in order to avoid their appearance, it is enough to observe simple operating rules and conduct timely maintenance of a trimmer gearbox for grass.

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.

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.

Reducer device

In order to better understand what lubricant is needed for your trimmer for grass, you need to figure out how the gearbox works, what components it consists of and analyze the working conditions of these nodes.

The trimmer gearbox for grass is usually located at the lower end of the drive shaft and serves for two main tasks:

• Transmission of the rotational movement of this shaft Bobin with a fishing line or a mill
• Increasing the torque of motorcycles by reducing the number of revolutions

Typically, the gearbox consists of the body itself, shafts, several bearings, one or more cylindrical and conical gears, seals (see. a photo).

The drive shaft at high speed is rotated by the leading shaft with the lead gear. The driven gear has more teeth and therefore the driven shaft rotates slower. But the torque is increasing on it. Each shaft is installed in the housing on two bearings.

When the trimmer for the grass for the gearbox, vibrations and shocks associated with a change in resistance to rotation from the interaction of the cutting node with grass, and shrubs are transmitted. Grass or dirt sticking to knives also with a high constantly changing speed of rotation contribute to the occurrence of dynamic vibrations and vibrations.

In general, we can say that the reducer nodes operate at a high speed of rotation and dynamic loads. At the same time, high contact voltages occur on the teeth of the gears, bearings experience transverse vibrations.

Temperature regimes are medium, since the tool is designed to mow grass, and this work is usually performed in the summer, at positive temperatures. As a result of friction, the nodes of the gearbox are heated, but excessive heat is removed by the lubrication and cooling of the gearbox body with atmospheric air.

Strong heating is a phenomenon uncharacteristic for the gearbox and indicates the need to repair the node or its lubrication.

Which oil should be used for a gearbox of a trimmer for grass?

In this case, the mechanical part of the trimmer for the grass is loaded with the contact forces on the teeth, the resistance of the reaction from the sticking of grass (sometimes with dirt), dynamic, shock loads due to the constantly changing torque. The transmission oil of a trimmer for grass should fully consider these features, so the choice of the brand should be strictly individual.

The following factors are taken into account:

• Manufacturer’s brand. Each brand is unreasonably focused on its own lubricants (you can talk about cheap Chinese products later). This applies to manufacturers such as Husqvarna, Stihl, Huter, Makita and others. The exception is domestic trimmers for grass: for example, Caliber in the user manual does not indicate a brand of lubricants
• Vasic oil. It is known that all lubricants are divided into three groups. high.speed (colloidal systems containing various additives), elastic plastic compounds for universal use and solid lubricants that soften during operation.
• Good adhesion to the surface of the transmission parts, as a result of which the oil is not pressed into the gaps or is not collected.
• Gear consumption of lubricants. Here you should rely on your own experience and expert advice, since some manufacturers of trimmers, based on the availability of their own service centers, usually do not give clear recommendations regarding the life of the gearbox between two lubricants.

The oil consumption also depends on the temperature at which it stores its oil. When the gearbox heats up to 40 ° C, its working conditions are considered satisfactory, and grease is sufficient.

It is believed that universal oil for a gearbox of a trimmer for grass does not exist, but this is not entirely. In fact, a suitable lubricant will be the one in which the following components are present:

• Anti.sympathetic additives that do not contain toxic lead;
• Solid oils with the presence of graphite or disulfide molybdenum (the latter is preferable because the oil is completely stored for a wide range of shaft speeds);
• Only mineral (inorganic!) Oil with a high degree of cleaning.

Gear Grease Oregon or Champion EP-0, domestic compositions Oleo-Mas, Litol.24 or AZMOL 158, as well as recommended by the manufacturer of a particular model of a trimmer for grass, fully comply with these requirements.

Lower gearbox

Stihl lawn mowers are well.deserved popularity

The second class belong to universal medium.power units up to 2.2 liters.With., intended for field and landscape work. In such designs, a straight hard shaft is used, which allows you to equip this class with saw steel knives for nozzles with help which can be cut down by shrubs and small trees. The design provides for a conical served gearbox. What lubricant to use for the reducer of the lawn mower. A special, under the brand name is the name “stihl” or ordinary lubrication of lip.

Engines from 6.3 to 8 liters.C is intended for professional use in forest or horticultural farms. The name of them is black cutters, these are the most powerful motorcycles for working in large areas, cutting small shrubs and trees. In the arsenal of a working tool there are saw wheels for cleaning bushes with a diameter up to 7cm. Bigorezes are equipped with an anti.vibration system, thanks to which working with such a tool becomes more comfortable. What lubricant to lubricate the gearbox of the lawn mower with powerful drive mechanisms, the lubrication of the Reducer of the Stihl lawn mower is carried out by a special proprietary or grease “STIHL” or production of Litol 24.

How to choose a lubricant

During operation, the components of the mechanism are loaded with contact efforts on the teeth, resistance reactions when garbage enters, as well as dynamic and shock loads. Depending on the features of the load, you should choose how to lubricate the gearbox of the trimmer for grass.

When selecting, the following factors should be taken into account:

• manufacturer’s brand;
• the viscosity of the lubricant (the selection of this parameter depends on the rotating moment of the shaft);
• adhesion to the surface of the parts of the node;
• The intensity of lubrication consumption (the ambient temperature should be taken into account, type and volume of work).

In the absence of the necessary lubricant, you can use the universal. The latter must contain some components:

• anti.sympathetic additives (without toxic lead);
• highly purification mineral oils (inorganic);
• solid lubrices with graphite or disulfide molybdenum.

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.

Place of grease of a trimmer for grass

For uninterrupted operation and durability of the mechanism, a thorough inspection and care should be carried out. An important point is the lubrication of moving parts. In most cases, these are:

Popular among users is the multi-purpose waterproof lubrication “Litol-24”. Operating temperature interval. from.40 to 120 degrees. This lubricant is used in friction nodes and is effective at elevated temperatures.

How to lubricate the gearbox of a trimmer for grass?

The lubrication of the gearbox is carried out by laying the lubricant in a special technological hole without dismantling the node.So, in order to lubricate a trimmer for grass, you need to perform a number of simple actions:

• Before starting work, we turn off the power tool from the network. In gasoline devices, in order to avoid leaks, it is advisable to drain gasoline (or during the work to ensure that the device does not turn over)
• With the help of a tool that is included in the supply of a trimmer for grass, it is necessary to turn out the cork in the gearbox body
• If we change the lubricant completely, then wash the gearbox. To do this, pour some cleaner into the case (white spite, gasoline, etc.), rinse the gearbox and drain. The procedure is repeated several times until completely cleaned
• We put a new lubricant in a gearbox. To do this, insert a tube or syringe into the hole and squeeze 2 5 ml of grease there
• We wrap the cork
• We turn the shaft several times manually, then turn on the motorcycle tank for a short time at low speeds without load, so that the lubricant is evenly distributed along the friction surfaces

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.

In many videos, masters recommend using lubrication for a clock, this is the best option. In its absence, to lubricate the shaft of the gas mowing rod, you can use lititol-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.

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.
