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.


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.

Many Trimmeres users do not pay much attention to servicing their tools. In particular, this applies to such a node of motorcycles as a gearbox. The work of the gearbox is associated with heating.

Scythe vs Brushcutter 1. South West Annual Scythe Festival. June 2010

With prolonged operation, motorcycles occur regular overheating of the gearbox, which leads to its breakdowns. Reducer breakdown leads to the fact that the tool is unsuitable for operation and it must be repaired.

lubrication, trimmer, grass, gasoline, champion

Reducer repair is an expensive event, so it is recommended not to bring the tool to such a state. The main reason for overheating of the gearbox and its failure is the absence of lubrication in it.

The article tells how to properly lubricate the gearbox of a trimmer for grass to avoid its breakdowns.

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.

What to lubricate?

If you have an electric cross with the lower location of the engine, then it does not need to lubricate anything in it, because the engine is equipped with underlying (closed) bearings, in which the lubricant is laid for the entire service life.

In electrimmers with the upper location of the motor, fill the bar with grease, because inside it are bushings, which, together with the tissue shaft, form sliding bearings.

If you have a tool with an upper motor and a straight bar, then fill the bar and gearbox with grease.

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.

How to lubricate the gearbox of a trimmer for grass?

All these nuances and features of the service and lubrication of the device have already been taken into account by the manufacturer. The operating instructions are given recommendations which material can be used for maintenance. Most often, there is not a specific brand brand, but those generally accepted standards to which it should comply with.

If there is no way to purchase the material recommended by the manufacturer, or it is not indicated in the instructions, then the choice of lubricants is made independently.

The lubricant must take into account all the above factors. temperature regime, high rotation speeds, dynamic loads and vibrations.

An important requirement for lubricant is also its ability to remain in the friction zone, not to be dumped under the influence of centrifugal forces during rotation and not squeezed out under load.

Lubrication for the gearbox should have good anti.corrosion properties and reliably protect the nodes from the formation of rust as a result of the effects of atmospheric moisture.

Based on these requirements, the selection of lubricants is carried out.

You can not rack your head, but purchase a specialized tool for servicing electro- or gasoline. Such materials are now in large quantities are offered as manufacturers of motor- and electrical core, as well as other companies.

To facilitate the life of the user, well.known manufacturers sometimes offer universal lubricants that are suitable for servicing the entire garden technique of this brand. You can use such materials.

You can maintain the reducer service with lubricants of general.industrial purpose. The main thing. So that they correspond to the operating conditions as much as possible and contain anti.sympathetic additives and filler in the form of solid lubricants (preferably molybdenum disulfide).


This tool of the American company NAC was developed for lubricating the angular gearboxes of motorcycle. It is made from mineral oil, thickened by a lithium complex and a special set of additives.

Lubrication has moisture resistance, excellent antioxidant and anti.corrosion properties.

Champion EP-0

This is a universal lithium lubricant with a consistency of 0 according to the NLGI system is designed for gearboxes operating in high mechanical stress conditions.

Lubrication provides long.term lubrication, prevents corrosion, protects from wear of the formation of bully and effectively reduces friction losses.

Lubrication is available in tubes with a volume of 50, 120 and 250 ml.

Hammer Flex 501-027

This special semi-liquid lubricant for gear gearboxes of electrical and benzo-tools with antioxidant, omedinous (EP) and anti-symbolic additives ensures reliable operation of the tool for a long time.

The lubricant penetrates the friction zone well and has excellent lubricant and heat.heating properties, preventing overheating.

Many users for lubricating a trimmer for grass successfully use even ordinary cheap lubricants, such as Shrus-4 or Litol-24.

Shrus 4

This is mineral lithium lubricant with the addition of molybdenum and additives. The presence of a carrone filler provides it with a high bearing capacity.

Shrus 4 also has excellent anti.zadyr characteristics, good anti.corrosion properties. It maximally reduces friction and minimizes the wear of friction surfaces.

A significant advantage of this material is its low cost.

Lubrication is made by many manufacturers and is available in a wide variety of packages.

Litol 24

Lubrication of Litol 24, like the previous one, was developed back in the USSR and gained great popularity due to the universality of application and accessibility.

This is a purely lithium mineral lubricant without adding any fillers and additives.

There are currently a large number of more advanced lubricants.

It has a low level of operational characteristics, but for a short time it is still capable of performing protective and anti.intelligence functions.

Incredibly low cost makes it still attractive for many owners of garden tools.

Chips on the choice

Now let’s try to understand how to choose high.quality oil for a trimmer for grass working on gasoline. The main feature that is required to pay attention will be an alkaline number. The moment excludes the oxidation of the parts that have friction, and slows down their deformation as much as possible. The more this composition is used, the faster it loses alkalinity and becomes more oxidized. The optimal indicator of acidity (pH) is a value of at least 8-9 units.

The second important factor, which also has a serious impact on the operation of a gasoline trimmer for grass, is the viscosity of the oil. This characteristic determines the possibility of using the device at various temperatures. Summer grades of oils begin to thicken already with a minimum decrease in temperature.

But given that such trimmers for grass are usually used in autumn and spring, it will be best used to use just oil with summer marking.

The third moment, the importance of which should not be understated. the temperature of the flash. This indicator should not be less than 225 degrees. Otherwise, the composition will burn very quickly and the load will begin to increase on the piston group, which will determine its accelerated wear. In addition, oil for a 4-stroke engine is not suitable for a 2-stroke. Namely, the last type of motors is used in the vast majority of benzocosyles.

If we talk about manufacturers, you can make a small rating that will allow you to navigate in the compositions offered by various manufacturers. For example, STIHL offers high.quality synthetic and mineral oils that have already proven themselves as an excellent solution at any time of the year.

Shell Helix Ultra oil is considered very good. Experts note its high characteristics and excellent indicators of alkalinity and viscosity. In addition, the products of such brands as Oleo-Mac, Motul, Hammerflex, Echo are considered worthy. If we talk about the products of domestic brands, then you should pay attention to Lukoil oil. Its price is several times lower than foreign analogues, but it has high quality and good technical characteristics.

In general, a synthetic or semi.synthetic oil that has a marke of TV or that is an ideal solution.

How to use?

Information on the proportions of the use of oil was given above. We will immediately say that you should not deviate from these values ​​and dilute gasoline by eye. At best, you just need to change the oil, and in the worst one cannot avoid breakdown of the motor.

It is important and be able to prepare the mixture correctly. You can’t pour it into the gas tank. It is better to pour oil into a special container where gasoline is already contained. A plastic bottle of mineral water is perfect for this. It is very important here that it is clean, due to which a bottle of beer or milk will not work. And it is better that it is liter or two-liter, as to calculate how much oil to fill in a 1.5-liter or 1.25-liter bottle will be difficult for many. It will also be necessary to have a syringe at hand, which will perform the function of the dosimeter. It is best to take ordinary medical for 10 or more cubes.

Now step by step will we explain how to make good oil for a gasoline trimmer for grass.

  • First you should find out exactly what type of oil is required for a specific model of braids for grass, as well as find out the exact ratio of gasoline and oil to create a mixture.
  • Then you need to fill the container. The container should not be filled with gasoline to the end, because the oil should still fit there;
  • Now we collect the right amount of 2-stroke oil into the syringe and pour it into a bottle of gasoline. You cannot do the opposite, otherwise you will need to replace all the ingredients, and the mixture will need to be done again.
  • Close the bottle with a lid and stir. It is important not to forget that you need to stir the mixture if there are words Premix on a bottle with butter. If SelfMix is ​​written there, then after mixing substances everything is poured into the tank.

Now it remains only to refuel the gasoline trimmer for the grass, and you can carry out the necessary work.

About how to choose oil for gasoline trimmers, watch in the next video.

Operating advice

Before the first launch of gasoline models, it is recommended to run them without load. This is done in the following sequence:

  • A braid for herbs for 5 minutes warms up at idle;
  • the air damper opens the transfer of the lever to the “VCL” position;
  • Gas is squeezed into ½ from the full for 30 seconds;
  • After that, the gas is dumped, the trimmer for the grass works at idle for another 40 seconds and turns off.

It is advisable to repeat this cycle of the for half an hour. After that, you can let the device work at idle for another 3 and a half hours.

During operation, it is important to carefully comply with all the requirements of the instructions for use. Before each use of a trimmer for grass, it is recommended to tighten all the bolts.

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.

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.


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.
