How to grease the champion gas toss gearbox. How to choose a lubricant

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.

Reducer device trimmer for grass

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

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

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

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

Motokos is equipped with gearboxes with different types of gears:

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

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

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.

Types of gearboxes for a trimmer for grass

It is worth noting that the basic components of cylindrical mechanisms are toothed cylinders. Most trimmers are equipped with worm gearboxes, but much depends on the decision of the manufacturer and other features.

A feature of the planetary type of transmission is the coaxial location of the shafts, while conical objects have a crossing placement. Gear gear is relevant only for those units that are used in certain temperature conditions. over, for them, any mechanical damage can become a fatal.

The reducer lubrication process

A gearbox is a mechanical device that is designed to transmit torque from engine to cutting equipment. Located in the lower part of the trimmer for the grass.

Immediately before preventive work, an electric cap (or a plug plug) should be removed). It is forbidden to turn the trimmer for grass to avoid fuel leakage. To replace the lubrication, disassemble the device.

The disassembly process consists of the following steps:

• The side screw is twisted.
• If there are no traces of lubrication, then it should be added (3-4 grams).
• Next, the transmission is scrolled manually. This is done for uniform distribution of material by gears.

The operation is carried out several times. The knot should be tightly filled with lubrication. At the end of the operation, the screw is installed in place and tightly delayed.

To lubricate the gearbox of a trimmer for grass, it is necessary to clean the cork and the place around it from pollution, and then unscrew it. The lawn mower is laid on the left side. Rotating the gearing, at the same time added lubrication to the gearbox body until it is filled.

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.

The reducer lubrication algorithm

To lubricate the gear mechanism of the gearbox, there is no need to disassemble the node. for this, a special hole is provided in the upper part of the case. In addition to the gear, it is necessary to carefully lubricate the elements such as the bearing node. The wear of its compacted walls leads to the fact that the lubricant comes out of the seat and the vibration of the technique begins. This problem is relevant for Chinese trimmers. The decision would be to replace the “native” bearings with high.quality details. The flywheel is also subject to lubrication. during operation, the part is covered with fragments of grass, creating additional resistance during kosbe.

Solid lubricant or oil are placed inside through a hole protected by a screw. At the same time, the following actions are performed:

• The gearbox body is carefully cleaned from contaminants, especially next to the plug to eliminate garbage entering the node;
• A special device is supplied with a motorcycle, it is extracted by a cork;
• From a tube or with a syringe, a lubricant is inserted into the hole, smoothly turning the cutting node so that the substance is evenly distributed along the gears of the gear;
• Return to the same cork.

The lubrication of the gearbox is required to be carried out annually, and with intensive operation, this procedure should be performed every 20 hours of operation of the tool. If signs of breakage appear, the lubrication site should be treated in the very near future.

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:

In addition to the gearbox, it is also necessary to regularly lubricate the shaft of a trimmer for grass. This is the norm of proper care of the device.

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.

If the composition used for lubrication has good adhesion, then it is practically not squeezed out of the gearbox through the gaps.

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.

The algorithm for self.lubrication of the gearbox

To make lubrication of the gear ratio, its preliminary disassembly is not needed. A special hole for these purposes has already been laid in the device (it is shown in the photo below). In addition to gears, when lubrication, you need to pay attention to such elements of the mechanism:

Pour oil or apply solid grease through a tavniper closed by a screw. At the same time, they perform actions in the following sequence:

• The gearbox body is cleaned of dirt and adhering grass, especially thoroughly the plot around the plug so that the garbage does not get inside the mechanism;
• Using the appropriate tool (often it comes with a trimmer), the cork is unscrewed;
• The selected lubricant is introduced from the tube into the open technological hole, or using the syringe, as shown in the photo further;
• screw the cork in place.

When making lubrication, you need to rotate the knife so that it is evenly distributed through the teeth of moving gears.

If for any reason the gearbox needs to be disassembled, then the old lubricant must be completely removed from the entire surface of the gears and housing, shaft, and only then use the new. The disassembled mechanism is conveniently lubricated with solid compositions.

The entire reducer lubrication process is demonstrated in the video:

Lubricating the gear node is required at least once during the year, but it is recommended to do this every 20 hours of intensive use of motorcycles. If the first signs of malfunctions with the mechanism appear, then you need to make lubricants as quickly as possible.

How to replace a trimmer gearbox for grass: an algorithm of action

To replace the gearbox with a similar part from the same manufacturer, it must first be disassembled and removed from the bar. At the same time, they act according to the following algorithm:

• weaken the fitting bolts located under the transfer mechanism;
• Using round.drawers, remove two corkscrew rings;
• Applying the puller, pull the bearings from the driven and the leading shafts;
• Then collect the mechanism, in the reverse order by installing all spare parts.

The disassembled transmission mechanism is shown in the photo below.

If the puller is not at hand, then you can try to gently knock down the bearings. When they have stuck and do not move at all, you can heat them using an industrial hair dryer (at a temperature of 600 ° C) and remove.

Collecting a gear node is easier than disassemble it. Only a light tapping with a hammer for planting parts in place may be needed. After assembly, it is imperative to check that the driven shaft turns out by hand.

Когда есть необходимость замены передаточного узла неоригинальной деталью, тогда следует учитывать их взаимозаменяемость. At the same time, it should be taken into account:

• the diameter of the bar (this parameter often is 25.4 or 26 mm);
• The parameters of the drive shaft. the shape of the docking space and the diameter (its common value is 8 mm);
• option of consolidation of protection.

If the considered parameters coincide, then it will be possible to set a part from other models.

Timely lubrication of the gearbox will ensure its prolonged operation without repairs. In addition, modern materials protect the metal from corrosion well, increase its wear resistance. When choosing, preference should be given a lubricant recommended by the manufacturer of the operated trimmer for grass. If such compositions are not possible to purchase, then the analogs considered or other suitable in properties should be applied. When it is necessary to disassemble the mechanism during the repair, this should be done carefully so as not to damage individual parts.

The frequency of processing

Anyone who knows how to lubricate a modern gearbox on a motorcycle one will quickly select the necessary grease. Proper care is a guarantee of the durable use of a trimmer for grass without repair. In this regard, the mechanism with gears is lubricated after ten hours of operation of the device or in case of overheating of the gearbox. This is determined by the usual touch of the hand to the case of the product. The main thing is to choose the right trimmer for the grass. If a large area is required to care for a lawn of a large area, then a professional model with an enlarged gearbox is best suited.

The gearbox is used in order to act a spinning mechanism and “force” it to work. Its design can be different, depending on the purpose of the tool.

With the help of these devices, the mechanism of motorcycle is driven and the mechanism. On the market you can reduce or increase the speed gearbox for a trimmer for grass of various types.

Popular are two- and three-stage models of double or detailed schemes that are resistant to loads and have a high level of efficiency.

• Worm. A compact tool is the most common type. It has an enlarged torque, simplicity of design. The worm model does not make noise, but at the same time gives high performance. The peculiarity of the tool is the presence of a self.control function.
• Globoid worm. It has a slightly convex shape, is characterized by high drive power and increased torque.
• Cylindrical. The model has cylindrical gears, is distinguished by variability of the structure, high power. The resource is from 25 thousand. hours.
• Conical. The design uses wheels with circular, straight teeth. It is characterized by high endurance and simplicity of the device.
• Conical-cylindrical. Intended only for large equipment. Has a low load ability.
• Nozzle. It is mounted on the output shaft, without additional gears, connections. The model is compact and non.fingered.
• Planetary. One of the most powerful tools that has a complex design. It is mainly used in mechanical engineering.

Motokosa gearbox mainly has a nozzle worm type. It provides high quality of the work of trimmers.

The process of lubrication of gears

When lubricating the gearbox located in the upper part of the trimmer for the grass with plastic or thick grease, remove the cover cover and only then apply grease on its gears. But before that, the developed lubricant is removed.

Maintenance

The most important thing in servicing the gearbox is timely and regular lubrication. This procedure is necessary to reduce mechanical friction and, as a result, heating and wear of contacting parts.

Lubrication of moving details, especially gears and shaft, should be carried out according to the rules printed in the instructions for the operation of the device.

If for some reason you do not have access to this information, remember important rules.

• Lubrication of structural elements should be carried out once in 8-10 hours of operation of the device.
• plentiful and frequent lubricant is necessary if you have installed new gears in return for the damaged if the device is shy of knife rotation or the gearbox gives out uncharacteristic noise during operation.
• Carefully select the lubricant. Many manufacturers of garden equipment also produce accessories for them, including lubrication. An ideal option would be the use of “native” composition. Depending on the degree of consistency, plastic, semi.liquid and solid lubricants are distinguished. The first type is used for both gear and screw gears, therefore it is considered universal. The second type is a suspension containing additives and additives. The third type in its original condition is similar to the first, so carefully study the label and instructions for the lubricant.
• To lubricate the gearbox, you do not need to disassemble it. the design of a trimmer for grass for this purpose provides for a special opening. Many manufacturers produce lubricants in the form of tubes with a long nose. The diameter of the input opening for lubrication is not always equal to the diameter of such a nose. This problem is easy to solve with the help of a regular syringe, the use of which has another plus. accurate control over the amount of squeezed lubricant.
• Also in the process of maintenance of a trimmer for the grass, the air filter is cleaned. To do this, it is necessary to remove the casing, remove the part, rinse with gasoline, dry, clean the place of planting from accumulated dirt. Next, insert the filter in place and fix the casing.

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.
