Complete disassembly of the gearbox Motokos for removing wear of wear and lubrication products

How to lubricate pushing the repair of the gearbox Motokosa? Whatever the brand of motorcycles, the second most importantly after the engine is a gearbox, consisting of two braids of gears, the smaller of which is the leading, the large one is the driven.

The gearing rotating in the bearings is located in the case consisting of two symmetrical halves, and, tightened by each other. The lead gear receives rotation from the engine on the rod, which ends with the slots (usually 7 or 9), the led transfers rotation of the spindle, which serves to plant the working body. A drum with fishing line, cables or cutting disk. The gear bearings from the spindle side are closed by the oil seal, which protects the supports and grease in them from pollution. To replenish it, a bolt is provided on the case, unscrewing which you can add grease during the operation of the tool.

Regular lubrication of gear gearbox Motokosa is so important that it is worth talking about this separately. If we exclude work with cutting disk, when it clings to a stone or a border and sends an oncoming shock impulse to the gearbox, which leads to a breakdown of the tooth of a driven gear, parts of which gradually spoil all the clutch, the lubricant can delay the repair of this important unit and extend the service life of the service in several once.


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.

What lubricant should be used for a trimmer gearbox for grass?

In the process of work, the mechanical part of the trimmer for grass is loaded with contact efforts on the teeth, resistance reactions from adhering grass (sometimes with dirt), dynamic, shock loads due to a constantly changing torque. The lubricant for the gearbox of the trimmer for the grass should fully consider these features, so the selection of the brand should be strictly individual.

The following factors are taken into account:

  • Manufacturer’s brand. Each trademark is not unreasonably focused on lubricants of its own manufacture (you can talk about cheap Chinese products later). This applies to manufacturers such as Husqvarna, Stihl, Huter, Makita, etc. The exception is trimmers for domestic grass: for example, the caliber in the user’s instructions does not indicate a lubrication brand at all.
  • Break of lubrication. As you know, all lubricants are divided into three groups. High.Speed (colloidal systems containing various additives), plastic compounds of universal use and hard lubricants softening during operation.
  • Good adhesion to the surface of the parts of the gearbox, as a result of which the lubricant is not squeezed into the gaps or outside the node.
  • The intensity of lubrication consumption by the gearbox. Here you have to focus on their own experience and recommendations of specialists, since some manufacturers of trimmers, hoping for their own service centers, do not give clear recommendations at all regarding the period of the reducer between two lubricants.

The main malfunctions and methods of elimination

For each buyer, the specialist will tell you how to lubricate a trimmer for grass with a gasoline model of the customer is best. For each of the motorcycle, these procedures do not have strong differences, since the equipment consists of mechanisms of the same purpose. And so, when it was determined by what kind of oil to make the lubrication of this node, you can proceed to the process itself. For example, we consider the process of processing the gearbox of the trimmer for the STIHL grass in phased performance:

  • Using the required key (most often hexagonal) on the gearbox body is unscrewed.
  • Using a syringe or directly from the tube, if there is a supply nozzle, is introduced into the opening hole 1-2 ml of grease.
  • Twist the screw.

WOW! Hidden, Secret Greasing Spot On A Weedeater

When performing a manually lubrication, for example, when servicing the upper gearboxes, it will correctly perform maintenance by analyzing the gear housing housing, where the oil base is laid into a stratum laying zone and on them, tracing that all teeth are covered before they are founded until they are founded before. By wear of old oils. Their traces are first deleted. Turning to the “Kosi Cos for Grass”, experts will help you choose the right grease that it is best to use for your trimmer for grass. Also, when performing complex services, we will find the necessary spare parts for you, like a bobbin for a trimmer for grass or candles, knives, ignition elements and others.

How often to lubricate the gearbox gearboxes

In determining the one, how often should the gearbox of the lawn mower should be lubricated, we note that with proper care of the device, it is considered ideal to introduce the oil in filling the gear unit with lubrication during every 10 hours of operation of motorcycles, or in accordance with the degree of heating and changes in the sound of a working gearbox as, for example, the closed upper gearbox of the benzotrimermer. Using this manual or contacting the “Kosi-Cos for grass”, you can find out in detail about what oil is used for your tools and how to replace the lubricant yourself, as well as what are the best spare parts for a lawn mower to buy when breakdowns or pro-costs for a non-stop working process.

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.

Necessary tools and materials

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

Hexagonal key for opening the reducer lubricant hole

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

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

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

We open the gearbox

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

Spring refueling action

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

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

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

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


The syringe is inserted into the gearbox hole

First, the syringe is inserted into the gearbox hole.

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

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

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

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

Activation of the gearbox

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

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.

How to choose a new one and replace

The lower gearbox is the most loaded part of the trimmer for grass. Even under normal operating conditions, it is susceptible to wear: microcracks appear in the metal that gradually increase; gearboxes of the gearbox also become unusable over time.

To purchase a new gearbox for replacement, remove the old knot and take it with you to the store. Keep in mind that each manufacturer produces these parts that are fundamentally not different, but the sizes can be unequal. Therefore, universal cheaper analogues are not suitable for all models.

To replace the gearbox, the following tools will be needed:

  • Flat screwdriver suitable in diameter to the hole in the lower part of the assembly body;
  • Set of keys-heads, the size of which is selected for a specific tool.

Replacement process

  • Unscrew the coil from the gearbox. It is quite simple to do it, as it turns on the thread of the gear of the gearbox. It is enough to insert into the hole between the mechanisms, the screwdriver, and then gently scroll the coil until its end falls into the deepening of the slots. Holding the screwdriver in this position with one hand, the second unscrew the coil with a fishing line.
  • To disassemble the structure consisting of a gearbox and a rod, it is first necessary to unscrew the centering bolt of a faulty mechanism, and then weaken the second (clamping) bolt.
  • Remove the old gearbox from the bar.
  • Put a new spare part according to the same algorithm, acting in the reverse order.

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.
