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.

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.

With rare exceptions, both electric and gasoline braids for grass with the upper engine are available. This makes the device safer and allows even wet grass to mow without the risk of moisture entering the engine.

Varieties

Now there are two main types of trimmers under the Champion brand:

Unfortunately, the company does not produce electric models with battery power. All products are equipped with a reel coil of cutting fishing line and a belt with a thigh protection system. Let’s look at a line for a trimmer trimmer for Champion grass in more detail.

Models of a brush

Such models of champion gas trimmers are now available on the market.

  • T252. The simplest, cheap and compact model weighing less than 5 kg. It is equipped with a two.stroke engine with a capacity of 0.75 kW with a volume of 25.4 cubic meters.

The cutting block uses a wire with a diameter of 2 mm, which provides a cutting area with a width of 38 cm.

These characteristics allow you to use this option to care for small lawns with thin grass.

Lubricant for a trimmer gearbox for grass. Than and how to lubricate?

Sometimes, in the midst of intensive spying of herbal, your trimmer for grass begins to make unpleasant, grinding sounds. This complains about the lack of lubricant gearbox. the most intensely loaded node of the device. And soon, these “warnings” may follow the junction of the drive.

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.

How often to do it?

To achieve the greatest effect, lubricate all the rubbing elements after 15–25 hours of operation. Even if you apply not enough lubrication to some detail during the next service of the electrimmer, but during the next service, correct this, then the corresponding rubbing pair will not receive severe damage.

In addition, the design of inexpensive, as well as some expensive models, an electric core with a direct bar leads to a loss to the oil gearbox through an ineffective seal in the area of ​​the coil or knife installation area.

To correct this drawback, you will have to install a new sealing ring or put an emergency oil seal with another inner diameter, but even in this case the gearbox will need to be checked every 20 hours to make sure that there are enough lubricants.

What will happen if you do not grease on time?

If you mow the grass with a trimmer, the rubbing details of which have not received lubrication, then the following will happen:

  • The shaft will break the bushings, so a strong vibration will appear and the device will be more difficult to hold in his hands;
  • The gearbox will begin to bask, and the surface of the gears will be stolen, metal dust enters the crankcase, so the laying of a new lubricant will no longer give a result, because it will act like an abrasive paste, accelerating wear;
  • Over time, the gearbox will stop working and when the engine is turned on, the knife or coil will not rotate.

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.

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.
