Repair and lubrication of a trimmer gearbox for grass

With frequent, intensive use of motorcycles, the gearbox can start to heat up or make sounds uncharacteristic for its normal operation, for example, rattle. This indicates that the mechanism must be lubricated. If this is not done on time, then more serious problems will arise (for example, gears will be quickly worn out and you will need to replace them), up to jamming. Other breakdowns also arise with the transmission mechanism. Reducer repair and lubrication can be performed independently. for this you just need to familiarize yourself with the features of these work and stock up on some available tools.

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

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

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

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

Motokos is equipped with gearboxes with different types of gears:

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

Grease HEDGE TRIMMER. How GREASE AFFECTS YOUR TRIMMER!. Everything you need to know about GREASING

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.

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.

How and how to lubricate the shafts in the rod of motorcycles

Many new motorcycles, even sold in collection, do not have a lubricant on the shaft of the bar. As a result, it warms up, wears out, a light whistling rattle is gradually added to the sound of a working motor and vibration appears. To protect the technique from premature wear, it is enough to devote 10 minutes and just grease the shaft.

Materials:

First you need to disassemble the bar. In a conventional benzos, it is enough to disconnect it from the upper and lower reducer for this.

If a braid for grass has a collapsible bar, consisting of two parts, then it is even easier. It is only required to remove the connecting coupling in the center and dilute half.

If the braid for the grass has already worked, then when examining the shaft, or shafts in the case of a collapsible bar, you can notice scuffs from the central bushings. Such places and need lubrication.

A small amount of lubrication must be squeezed on a rag or fingers and process the shaft without passes. It is applied with a non.weed layer, but everywhere. Particular attention should be paid to the slots, since they are on the highest load, especially at the time of the knife of the knife braid for grass on stones and other objects.

The greased shaft is inserted back into the stack with a slight scroll. Thanks to this, part of the extra lubricant will remain on the central bushings, where it should be. Rotation will also help the hills to get into their seat on the gearboxes.

If a straight lawn mower with a non.vegetable bar is served, then it is simply attached back to the gearboxes. In the case of a two.part bar, short shafts are inserted into each half. After this, part of the rods join the center. If their slots did not hit, then you can simply twist your lower gearbox with your hand. Further, the jointed rod is clamped back with a coupling.

If the lawn mowing is inflow, such a rod maintenance should be carried out every season. The cord’s lubricant used well withstands high temperature, which excludes oil stoops with long operation of braids for grass. The same composition can also be used for lubrication of gearboxes. In them it can be pressed with a syringe if the tube does not have a nose. The lubrication frequency of gearboxes is higher than the shaft. Typically, manufacturers recommend this every 5 mothers.

How to lubricate the motorcase gearbox in a simple way

How to lubricate the motorcosa gearbox? Much users of trimmers do not attach importance to the overheating of the gearbox of the mowing head. And, of course, during a breakdown they immediately flee to the repair workshop. To save time and money on repair, it is enough to lubricate the gearbox before the season and forget about unnecessary expenses.Gearbox. One of the most loaded parts in this device and quite often fails. Therefore, he definitely needs periodic maintenance.

You will need it

We take the syringe, temporarily remove the piston from it. Place the lubricant in the cylinder. Usually this amount is 5-10 grams (a more accurate number is written in the operating manual for Motokos).

Do not be lazy to spend a couple of minutes after buying motorcycles and before the mowing season to lubricate this important node. And your tool will always be ready to work at any time and will last long, long years.

Rod and the drive of the working body

The bar has two very important functions: the first. forms a hard frame of the entire structure, the second. a shaft passes inside the metal roller rod, which connects the working organ with the engine. By the appearance of the rod, you can determine the class of the tool, if the bar is curved. this is convenient for work, but in this case the drive is a flexible shaft, which cannot convey a large torque. If the bar is straight, a hard metal rod passes inside, it can transmit more reliably and torque. Therefore, a professional tool always has straight rods.

How, what and how often it is necessary to lubricate the gearbox motorcosa for durable work

Motokosa gearbox and shaft inside the bar must be lubricated every 15-20 mothers of work. Then your tool for kosba grass will work out the resource laid for it without any serious failures and breakdowns.

To lubricate the lower reducer, the motorcycles turn the largest bolt under the hexagon, which closed the hole for lubrication of gears. In order to efficiently and controlled the lubricant of the lower gearbox, it is better to remove it from the end of the bar. To do this, we turn the fixing bolt also under the hexagon and weaken the nut of the fold bolt on the gearbox body.

The gearbox according to the factory instructions is lubricated with a special composition for gearboxes, but we use a lubricant from the UKO SHRUS-4 company, which is also very suitable for our purpose.

To introduce lubrication into the gearbox body, we use an ordinary medical syringe for 20 cubic meters, which we fill with grease. We insert the piston into place and squeeze out the lubricant into the gearbox, placing a syringe nose into a lubricant.

The required amount of lubricant is controlled by its appearance through the internal hole of the bearing, into which the end of the shaft is inserted. At the same time, air is removed through the hole from the gear cavity, which would prevent the gearbox from filling out if we had not removed it from the shaft.

After filling the gearbox, with lubricant, turn the gears with your hand so that the oil is evenly distributed along the teeth of the gears. Then add a small portion of oil, observing the process visually.

The reducer’s lubricant is completed on this, and we twist into a lubricant previously turned from there a bolt under the hexagon.

We proceed to the lubrication of the shaft, which rotates in the bushings fixed inside the bar with a certain step. The shaft is a steel rod, at the ends of which there are slots necessary for entering the engagement with the upper and lower gearboxes.

We apply grease not only to the helmets of the shaft, but also along its entire length to reduce the production of the shaft and bushings in which it rotates inside the bar. After lubrication, we install the shaft back, passing through all the bushings, and introducing into the ending with gearboxes.

The upper gearbox does not require lubrication, t. to. It has a closed bearing, and the lubricant from the gearbox does not go anywhere.

The lubricant is over. We put on the lower gearbox at the end of the bar, fix it on the rod with a bolt under the hexagon and tighten the nut of the fold bolt on the gearbox body.

How to properly serve a motorcycle

The device consists of the following mandatory elements:

Trimmer care involves monitoring the technical condition of each of them.

Engine care

When caring for a gasoline engine, it is worth paying special attention to the cleanliness of the air filter. it should not have sawdust and dirt. Foam filter should be constantly moistened with oil. Check should be carried out weekly, quickly change the filter as necessary. Before starting each work, you should check how the nuts and screws are tightened. It is also necessary to clean the muffler and candles from the carbon fiber as it is contaminated.

In the electric version, it is enough to follow the operating time prescribed by the manufacturer.

Serving cutting discs

If we talk about disks, then you should focus on how carefully the facets of the blades are sharpened. The sharpening should be carried out correctly, otherwise such a disk in the work will load the motor, which will only reduce the resource of the latter. A regular coup of bilateral discs should be carried out 180 ° for uniform wear.

Monitoring of the condition of the fishing line

How to care for the cordial part? The most important thing in this case is the use of a specially designed mowing fishing line.

In no case should you replace the fishing line for a trimmer with metal cables or wire. this is traumatic.

  • The fishing line for the trimmer must be periodically changed;
  • The diameter specified by the manufacturer is set;
  • Winding of the cord goes tightly, but without the intersection of the turns;
  • The head must be constantly cleaned of dirt and regularly lubricated;
  • Carefully monitor the degree of wear (otherwise the gearbox or shaft is deformed).

How to monitor the corner gearbox

The priority task of the user is to prevent the accumulation of dirt on it. This circumstance will not allow the details to cool normally. The second requirement is to use consistent lubricant (such as Husqvarna or like), designed for a reducer pair. Usually enough annual lubrication procedure.

What you need to know about the casing to protect

It is forbidden to work without a protective casing. initiative can be dangerous for the user and others. But it is impossible to select such details from among the non.violent, it is necessary to use the recommended by the manufacturer. Damaged casing should be changed in a timely manner.

Casings can be attached both on the bar and on the gearbox. In universal models (working and fishing line and disk) two different kokhuzha are attached. A special cutting plate that cuts off the excess cord can also be located on the “forest”.

We summarize what has been said about the main points of departure in this maintenance of the Hitachi brand Motokos:

Repair of small breakdowns

Little repair can do almost any person. In the electric motor, the user will only be able to check the contacts or replace the brushes. A lot of the elements of the microcircuit cannot be fixed without service intervention.

To prevent a breakdown of a gasoline engine, you need to blow the container with air before pouring new portions of the mixture. this measure will remove exhaust gases. Four.stroke engines are not recommended to be highlighted: the oil supply to the details may stop, which will disable the engine.

If the trimmer motor for the grass has broken, and the user does not have knowledge in the field of electromechanics, then it is best not to try to disassemble it, but to contact specialists.

But with such small breakdows you can cope with your own hands.

  • With a haggard inclusion toggle switch, you can independently replace it with a new. True, at the same time, knowledge of the basics of electrical engineering and the ability to work with a soldering iron will be needed.
  • With a wire limit, flexible wire (copper or aluminum) will help with a mowing head. You can also make a new stainless steel mount.
  • The torn fishing line for the trimmer can really be replaced by yourself. To do this, you can choose a nylon or nylon material, from 0.9 to 1.5 mm in diameter (you better know your own in advance). The drum is made manually, the fishing line for the trimmer is wound, after which it can be assembled.
  • The broken bar is also easy to fasten to brackets or rails.
  • With strong vibration, the motorcycle should be greased.
  • It is better to replace plastic knives with metal (stainless steel). They can be attached to the shaft with a sleeve and washer. This “transformation” will make even hard grass mow.
  • If the engine does not start, you need to do the following. briefly close the damper to enrich the mixture. You can also try to change the mixture. Then it remains to check whether gasoline comes, and if necessary, clean (or even replace a candle of incandescent).

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.

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.

Lubrication of the lower and upper gearbox

There are tips in which they recommend lubrication at the end of the season. However, most people believe that it is better to do this at the beginning of each season. When we repair the node and also carry out any disassembly, it is necessary to use lubricants. The gearbox must be additionally lubricated when an old trimmer is inserted for grass.

Modern trimmers for grass are equipped with a gearbox, which measures the angle of transmission of mechanical energy between the two components: shaft and head. Conquered gears are considered common, they easily withstand high speed, equipped with smooth hook, as well as an increased level of bearing capacity. The housing includes a shaft, a gear wheel, which is pressed on a driven shaft. In order to reduce friction, bearings are installed on the support points of the shaft.

Lubrication for a gasoline trimmer for grass

Correctly selected care for the motorcycle system gives a guarantee of durability and quality work of equipment. Manufacturers try to take into account all the nuances and prescribe which materials to use for service. Typically, a specific type of lubricant is not indicated, well.known standards are simply given to which lubricants must comply with.

Lubrication should be selected in such a way as to take into account the temperature, rotation speed, load dynamics and vibration. The main requirement is that this mixture remains in the maximum friction zone.

Lubrices should have good anti.corrosion properties, reliably protecting the nodes from rust.

Based on the above information, it should be noted that the manufacturers of the benzos are developing universal additional funds for their equipment. It can be served by general.industrial compositions. The main condition is compliance with operating conditions, namely, the presence of a substance against rust and lime, as well as a filler, which consists of a solid lubricant. The lubricant is poured into a gearbox into a special hole, while the node is not dismantled.

Replacement is performed quickly enough.

  • First, turn off the device from the network. From devices on gasoline, you must drain gasoline.
  • If the lubricant changes completely, then be sure to wash the gearbox. To do this, pour the cleaner first, then rinse the gearbox well, then drain. It is important to clean the body completely.
  • A special tool that is included with the trimmer, you need to turn the gearbox cork.
  • We apply a new lubricant: insert a syringe with a tube into the hole and squeeze out a lubricant (2-5 ml).
  • Manually turn the shaft, turn on the braid on small turns without load. This is necessary so that the lubricant is qualitatively distributed in places subject to maximum friction.

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.
