Lower gearbox
On mowers driven by a trimmer with working attachments, an adapter bevel gearbox is provided. The transmission of torque occurs through bevel gears. This type of gearbox comes in two types: serviced and maintenance-free. The name serviced - the gearbox received its ability to add lubricant to the working cavity to lubricate the gears. If the gearbox is not maintained, then the lubricant is supplied by the manufacturer for the entire service life, and the gearbox itself has a sealed housing. According to the manufacturer's developers, such measures increase the service life of the gearbox, since contamination does not get inside through leaks in the lubrication hole. The gearbox of a lawn mower is the most loaded part, transmitting force with a directional configuration, therefore proper care and proper lubrication is very important for the unit. What kind of lubrication is needed for the gearbox and repair of a bevel gearbox with = replacement of bearings can be seen in the video below.
Stihl lawn mowers are deservedly popular
Stihl brush cutters vary in class, motor type and purpose. Designed for caring for small areas to clearing large areas of weeds, bushes and young trees. In this regard, they are usually divided into classes. The first class includes amateur devices with low power up to 1.2 hp. By design, “Stihl” amateur braids are produced with a curved barbell. which makes it possible to exclude the lower bevel gearbox from the design, which significantly reduces the price and service. Brush cutters with a curved bar are designed to work with cutting equipment made from fishing line or polymer knives. They are comfortable to use in garden plots with small areas.
Class 2 refers to universal units of average power up to 2.2 hp, created for field and landscape work. In such designs, a straight rigid shaft is used, which allows this class to be equipped with sawing iron knives for attachments with which you can cut down bushes and small trees. The design provides for a serviceable bevel gearbox. What lubricant to use for the lawnmower gearbox. A special one, under the brand name “Stihl”, or ordinary Russian lubricant Litol is used.
Engines from 6.3 to 8 hp are designed for professional use in forestry or horticulture. Their name is brush cutters, these are the most massive brush cutters for working over huge areas, cutting down small bushes and trees. The arsenal of working tools includes saw blades for cleaning shrubs with a diameter of up to 7 cm. Brush cutters are equipped with an anti-vibration system, which makes working with such equipment more comfortable. What kind of lubricant to lubricate the gearbox of a lawn mower with massive drive mechanisms? Lubrication of the gearbox of a Stihl lawn mower is done with a special branded lubricant, either Stihl or Russian-made Litol 24.
Rod and drive of the working element
The rod has two very important functions: 1st - it forms a rigid frame for the entire structure, 2nd - a shaft passes inside the hollow iron rod, which connects the working body with the engine. Based on the external appearance of the rod, you can determine the class of the tool; if the rod is curved, this is comfortable for work, but in this case, the drive is a flexible shaft that cannot transmit large torque. If the rod is level, a rigid iron rod passes inside, it is much more reliable and it can transmit more torque. That’s why professional tools always have straight shafts.
features of selection and application of the composition
Sometimes, when intensively mowing grass, the trimmer begins to grind and make unpleasant sounds, which indicate a lack of lubrication of the gearbox. This unit is considered the most loaded, and therefore wears out faster. If it is not lubricated in a timely manner, the drive may soon jam!
Algorithm for self-lubrication of the gearbox
To lubricate the transmission mechanism, preliminary disassembly is not necessary. The device already has a special hole for these purposes (it is shown in the photo below)
In addition to the gears, when carrying out lubrication, you need to pay attention to the following elements of the mechanism:
- bearing unit;
- flywheel and starter coil pawl.
Fill in oil or add solid lubricant through a grease fitting closed with a screw. In this case, perform actions in the following sequence:
- clean the gearbox housing from dirt and adhering grass, especially carefully the area around the plug so that debris does not get inside the mechanism;
- using the appropriate tool (often it comes with the trimmer), unscrew the plug;
- the selected lubricant is injected into the open technological hole from a tube or using a syringe, as shown in the photo below;
- screw the plug into place.
When applying lubricant, you need to rotate the knife so that it is evenly distributed over the teeth of the 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, housing, and shaft, and only then a new one must be used. It is convenient to lubricate the disassembled mechanism with solid compounds.
The entire gearbox lubrication process is demonstrated in the video:
The transmission unit must be lubricated at least once a year, but it is recommended to do this every 20 hours of intensive use of the brush cutter. If the first signs of malfunctions with the mechanism appear, you need to add lubricant as quickly as possible.
Types of lubricants used
When choosing a lubricant, the following factors must be taken into account:
- degree of adhesion of the composition to the metal of the assembly;
- product brand;
- lubricant consumption by the transmission mechanism.
Well-known manufacturers, for example, STIHL, Husqvarna and others, in addition to trimmers, also produce lubricants for them. Such products not only reduce wear, but also protect the gear metal from corrosion. Therefore, for brush cutters from these brands, it is better to use their own lubricants.
If the composition used for lubrication has good adhesion, then it is practically not squeezed out of the gearbox through the gaps.
Different models use lubricant differently. This is determined to a large extent by the intensity of use of the brush cutter and the heating of the transmission mechanism. It is considered that the lubricant is sufficient if the temperature of the gearbox during operation does not exceed 40°C.
By consistency, lubricants for trimmers can be:
Based on their composition, the following types of lubricants are in demand:
- graphite, which significantly reduces friction, resulting in improved gear rotation;
- lithium, which is also an excellent anti-corrosion composition, saturated with additives that increase the wear resistance of the metal without harmful substances;
- universal, containing highly refined mineral oils and performance-enhancing components.
Examples of suitable lubricants are: Champion EP-0, Gear Grease OREGON, Oleo-Mas, Azmol 158, Litol.24
You should also pay attention to manufacturers' advice on this issue and use the materials they offer. You can buy them at specialized retail outlets

What lubricant should I use for the trimmer gearbox?
During operation, the mechanical part of the trimmer is loaded by contact forces on the teeth, resistance reactions from adhering grass (sometimes with dirt), dynamic, shock loads due to constantly changing torque. The trimmer gearbox lubricant must fully take these features into account, so the selection of the brand must be strictly individual.
The following factors are taken into account:
- Manufacturer's brand. Do-it-yourself repair of the trimmer Champion t 336 lawnmowers how to lubricate the shaft pcs video. Example. It is not without reason that each brand focuses on its own made lubricants (we can talk about cheap Chinese products later). This applies to manufacturers such as Husqvarna, STIHL, Huter, Makita, etc. The exception is domestically produced trimmers: for example, Caliber in the user manual does not indicate the brand of lubricant at all...
- Lubricant viscosity. As is known, all lubricating compounds are divided into three groups - high-viscosity (colloidal systems containing various additives), plastic compounds for universal use and solid lubricants that soften during operation.
- Good adhesion to the surface of gearbox parts, as a result of which the lubricant is not squeezed into the gaps or out of the assembly.
- The intensity of lubricant consumption by the gearbox. Here you have to rely on your own experience and recommendations of specialists, since some trimmer manufacturers, relying on the availability of their own service centers, do not give clear recommendations at all regarding the period of operation of the gearbox between two lubrications.
DIY grease for an angle grinder
A self-made lubricant for grinder gears consists of a base and a diluent. The basis of homemade lubricant is usually a CV joint with molybdenum disulfide or Tsiatim-221. They have a second NLGI viscosity, so for use in an angle grinder gearbox, the base must be diluted. As a diluent, it is best to use simple mineral industrial oil, which, for example, is I-20 oil. To obtain a viscosity of NLGI 0, you will need to mix approximately 70 percent base and 30 percent thinner. The resulting mixture is thoroughly mixed and ready for application to gears and bearings of angle grinders.
Making your own lubricant
Timely maintenance of any electric tool is the key to its long-term and trouble-free operation. A properly functioning tool is also a guarantee of safety for the person using it. Using the tips given above, everyone can choose the right lubricant for the angle grinder gearbox and replace it without resorting to the help of expensive power tool service centers.
How to lubricate the trimmer gearbox?
In the upper part of the housing, where the gear block is installed, there is a technological hole, which is plugged with a screw during operation of the trimmer. This screw is unscrewed, and 1.5...2 ml of lubricant is injected into the hole using the spout on the tube. If the lubricant was purchased in a different package, then a regular disposable medical syringe will be suitable for this operation.
After this, the screw is installed in its original place. This procedure, regardless of the user’s recommendations, should be performed every 10...15 hours of using the trimmer in operating mode. Other reasons for updating or replacing the gearbox lubricant are performing minor routine maintenance on your own (for example, cleaning and washing the gearbox gears before the start of the summer season), repairing the unit, preserving the trimmer for the winter, etc.
If the gearbox assembly is disassembled, it is recommended to completely remove any remaining grease from the surface of the parts, even if it does not have traces of oxidation or contamination. And only then apply new lubricant. After applying the lubricant, it is recommended to rotate the shaft several times by hand and make sure that the lubricant is evenly distributed throughout all gearbox parts.
When lubrication, special attention is paid to the following elements:
- Flywheel: as a rule, grass residues intensively adhere to its surface, and thickening grass juice creates additional resistance.
- The starter coil pawl, which constantly comes into contact with the grooves on the flywheel when the drive is turned on. In this case, not only mechanical wear occurs, but also mechanochemical corrosion of the flywheel-pawl joint, since the materials of this pair are different (the flywheel is aluminum, and the pawl is steel).
- Bearings, if their seals are worn out, and through them the remaining lubricant is squeezed out. In this case, the unit begins to vibrate intensely when loaded. This happens with Chinese-made trimmers, so in the future it is worth thinking about replacing the bearing assembly with a better one, for example, from the Swedish company SKF.

About the manufacturer Stihl
The history of this German brand begins in 1926. At the initial stages of its development, the company was engaged in the production and sale of various components for washing and steam machines. It all started, like many companies, with small production and a narrow focus, which made it possible to focus on the quality of the products produced.
In the early 30s, the first STIHL chainsaw was released, distinguished by its convenience and functionality even in those days. The company is developing at a rapid pace, constantly introducing new tools, which gives it the opportunity to enter the international market. And already in 1931, the first regular deliveries of products to Russia were organized.
Calm device
To date, the company has expanded its activities in more than 160 countries around the world, opening new centers and production branches in Switzerland, China and many other countries. This is understandable, because the company’s assortment is impressive: motor drills, gasoline sprayers, mowers, gasoline trimmers, chainsaws and much more. I would like to note that Shtil chainsaws are very popular due to their functionality and reasonable price.
How to replace a trimmer gearbox: algorithm of actions
To replace the gearbox with a similar part from the same manufacturer, it must first be disassembled and removed from the rod. They operate according to the following algorithm:
- loosen the coupling bolts located under the transmission mechanism;
- Using pliers, remove two corkscrew rings;
- using a puller, pull the bearings from the driven and drive shafts;
- then they assemble the mechanism, installing all the spare parts in the reverse order.
The disassembled transmission mechanism is shown in the photo below.
If you don’t have a puller at hand, you can try to carefully knock off the bearings. When they are stuck and do not budge at all, you can heat them with an industrial hair dryer (at a temperature of 600°C) and remove them.
Assembling the transfer unit is easier than disassembling it. It may only take a light tap with a hammer to seat the parts into place. After assembly, be sure to check that the driven shaft can be turned by hand.
When there is a need to replace the transfer unit with a non-original part, then their interchangeability should be taken into account. The following should be taken into account:
- rod diameter (this parameter is often 25.4 or 26 mm);
- parameters of the drive shaft - the shape of the connecting point and the diameter (its common value is 8 mm);
- option for securing protection.
If the considered parameters match, then it will be possible to install a part from other models.
Timely lubrication of the gearbox will ensure its long-term operation without repairs. In addition, modern materials protect metal well from corrosion and increase its wear resistance. When choosing, preference should be given to the lubricant recommended by the manufacturer of the trimmer being used. If it is not possible to purchase such compositions, then the considered or other analogues suitable for their properties should be used. When it is necessary to disassemble a mechanism during repairs, this should be done carefully so as not to damage individual parts.
How to lubricate the gearbox of a trimmer or brush cutter: proper care of garden tools | (Photo Video)
Many trimmer users don't pay much attention to maintaining their tools. In particular, this applies to such a mower unit as the gearbox. The operation of the gearbox is associated with heating.
During long-term use of brush cutters, regular overheating of the gearbox occurs, which leads to its breakdown. If the gearbox breaks down, the tool becomes unusable and needs to be repaired.
Gearbox repair is an expensive undertaking, so it is recommended not to bring the tool to this condition. The main reason for gearbox overheating and failure is the lack of lubrication.
The article explains how to properly lubricate the trimmer gearbox to avoid damage.
Recommendations for use
It is necessary to take temporary breaks from work. This is necessary to ensure that the device’s engine does not overheat and fail prematurely. For amateur models, a break is provided every 20 minutes for the same amount of time. For professional mowers, work must be interrupted every 50 minutes, in which case the downtime should be at least 10 minutes.
You need to monitor the condition of the fuel tank. If you do not plan to use the mower for a certain period of time, it is better to drain the remaining fuel from the tank compartment. This will help avoid damage to engine parts.

Design and principle of operation of a trimmer gearbox
A gearbox is a device for transmitting rotation to the cutting part from the motor shaft. Its second purpose is to convert the angular speed of rotation of the output shaft to lower or higher speeds. In the first case, the device is called a “demultiplier” and is used on trimmers with powerful engines, in the second case it is called a “multiplier” and is installed on low-power tools. The gearbox is always located at the bottom of the rod of gasoline and electric scythes of different brands, be it “Champion”, Huter or another brand.
The gearbox structure looks like this: The main parts are a gear shaft (to transmit movement from the motor) and a gear mounted on the driven shaft (to rotate the cutting unit). To reduce the friction force during movement, rolling bearings are placed on the support points of the shafts. They are protected by special washers that preserve lubricant and prevent dirt from penetrating into the seat. All parts are placed in a duralumin housing with a special technological hole for lubricant injection. It is necessary so that you do not have to constantly disassemble the unit to perform lubrication.
Thus, the design of the gearbox, depending on the model and brand that produced the equipment (for example, Sterwins, “Foreman”), includes several gears interlocked with teeth to transmit rotation and moving at high speed. Due to significant friction, they get very hot.
Removing and Lubricating the Upper Trimmer Shaft
First of all, we remove the lower part of the rod from the coupling, and then disconnect the coupling from the upper part of the rod (here we are talking about the coupling connecting the two halves of the rod).
Trimmer PRORAB-8406 with disconnected coupling and lower part of the rod
Now the most interesting thing: in some videos, like this one, holding the shaft coupling protruding from the top of the rod from below with pliers, knock it out of the rod along with the rolling bearing by hitting the pliers (here we are talking about the coupling connecting the upper and lower shafts). Some lawn mowers with a collapsible rod, as in the video, have a coupling connecting the upper and lower shafts that is pressed into the rolling bearing.
With our trimmer PRORAB-8406 and others like it, this number will not work. They do not have a rolling bearing, and the coupling (bushing) is a continuation of the shaft of the upper rod. There is a retaining ring installed at the top of this shaft, which must first be removed.
Place of attachment of the upper part of the rod to the clutch housing
- Unscrew the central screw completely. It secures the upper part of the rod, partially entering the hole drilled in it. Loosen the side clamping screws and remove the rod from the clutch housing.
- We push the shaft out from the top of the rod towards ourselves, as much as the play allows, in order to get to the locking ring and remove it. A special puller may be required*. Remove the retaining ring.
Retaining ring on the upper shaft of the brush cutter
- Without a locking ring, the upper shaft can be easily removed from the rod on the opposite side. We lubricate** it, not forgetting about the splines in the bushings (couplings) on the rod shaft and on the clutch shaft.
- We install the lubricated shaft in place in the upper part of the rod and secure it with a locking ring. We insert the rod into the hole in the clutch cover and align the hole on the rod with the threaded hole of the fixing screw.
- We screw in the fixing screw and secure the upper part of the trimmer rod with the side screws in the clutch cover.
- We clean the rod coupling from debris and install it from below to the top of the rod.
* I don’t have a puller, but I use two large paper clips to remove the retaining ring. First you need to straighten them, make half rings for your fingers on one side, and bend small hooks on the other.
** In many videos, technicians recommend using Shrus-4 lubricant; this is the best option. If it is not available, you can use Litol-24, which is rated for temperatures up to +130°C, to lubricate the shaft of the lawn mower. But solid oil, which has worse lubricating properties and operates at temperatures up to +70°C, is not recommended.
However, if you urgently need to lubricate the shaft of a lawn mower, but there are no suitable materials, then solid oil or even regular motor oil will be better than nothing at all.
Carburetor, muffler and ignition coil
To remove the carburetor, you need to have a socket 8 and an extension, with which it is convenient to unscrew the nuts securing the carburetor and air filter. Before dismantling the carburetor, it is necessary to disconnect the ignition wire and choke rod from the engine control lever and remove the lever, only after this the air filter and carburetor are removed.
The Shtil 180 muffler is secured with two nuts, which you need to unscrew to pull it towards you, it can be easily removed.
How to Adjust the Carburetor of the Shtil Fs 55 Lawnmower
Carburetor repair and repair
The trimmer is not a complex household appliance, since most of its faults are mechanical and can be successfully fixed with your own hands. Even if the engine fails for good reasons. for example, damage to the piston ring, repair is reduced to replacing parts.
And in a relatively conventional design, a part of the device such as the carburetor must be adjusted.
How does it work
Carburetor. This is a power system module in which liquid fuel and air are mixed before being supplied to the engine cylinders. Depending on the tool and its operating mode, mixing and feeding are adjusted accordingly.
The carburetor cutter is uniform in almost all cases. The FS 38 recreational price must be adjusted using the carburetor screw. Belongs to the category of floating devices. How to adjust the carburetor on a scooter. Honda part AF-34. The latter provide constant characteristics of the finished consistency.
The mechanism of operation of the module is as follows.
- Air enters the tube body with an air damper. Adjusting the carburetor of the fs 55 trimmer cooler in the video on how to adjust the carburetor. The latter increases or decreases the air flow depending on its position.
- In the area where the gas supply hole is formed, the tube has a hood. diffuser. Adjusting the fs 55 carburetor stop trimmer in the video is performed to adjust the idle speed. Here the flow speed increases.
- Fuel from the float chamber is supplied through the nozzle into the pipe. The float level determines the amount of fuel supplied. How to adjust 24, I removed the carburetor from the diode, I don’t know the rings on the pistons of the Honda DIO 34. Since the pressure in the chamber is normal, and in the pipe is low due to the high vacuum of air, gas is sucked through the nozzle.
- The accelerated air flow collects fuel and atomizes it, forming an air-fuel mixture of appropriate density.
- The mixture is sucked into the cylinder through a pipe.
The more the air damper in the pipe is open, the higher the air flow density and the more fuel enters the cylinder. Carbon lawnmower settings come down to the damping ratio at which the fuel consistency becomes good.
Signs of Imbalance
The carburetor adjustment, of course, is made during the manufacture of the device. Usually the need to regulate Owners will only be able to deliver fuel themselves after serious breakdowns, during which the module was removed and, for example, cleaned.
Symptoms of a problem with the settings are as follows:
- it starts but the engine stops here. since the engine can only operate when a certain amount of very “bad” gasoline is supplied, in other words, by blocking the supply channel, the engine stops;
- Very high fuel consumption, a lot of exhaust gases. the result of incomplete combustion of the consistency. In this case there is a lot of fuel, and the mixture is very thick.
Carburetor gasoline braids Ticho, Makita, Husqvarna and others are adjusted with adjusting screws. Sometimes a prerequisite for a malfunction is a violation of fixation. due to vibration or damage to the protective cap. You can find this type of failure by simply trying to turn the screw a little: if the lock is not tight, you should check the settings.
Removing the flywheel
The flywheel of the Shtil 180 chainsaw is twisted with great force, so to remove it you will need a head with a metal knob. The nut holding the flywheel is unscrewed with a 13mm head.
To block the crankshaft from turning, you need to unscrew the spark plug and install a piston stopper through the spark plug hole; if there is none, you can use an old cord from the starter, with knots tied to it and immersed in the cylinder through the spark plug hole.
It is strictly forbidden to keep the flywheel from turning by installing a power screwdriver or other tools between its ribs and the body; with this method of blocking from turning, the flywheel blades are not able to withstand the load and break off.

Sometimes the cutting head breaks, sometimes the cable breaks. Repair.
Once the piston in the cylinder is locked, you can unscrew the flywheel nut. The thread in the nut is normal, so you need to turn it to the left. Having loosened the nut, you do not need to remove it completely; just unscrew it until its upper edge is level with the tip of the shaft, after which a soft metal drift is installed on the nut and a sharp blow is made on it. Thus, the flywheel jumps off the shaft from a sharp impact and can be easily removed without the help of additional tools.
Lubricate the brush cutter, brush cutter: rod, drive shaft and other spare parts.
The drive shaft, which is located inside the rod, transmits rotational movements from the engine to the trimmer gearbox, and that, in turn, to the knife or fishing line (depending on the type of cutting equipment of your unit). All of these components, including the shaft, also require a lubricant to help prevent premature wear, breakage, friction, grinding, overheating or breakage. It is imperative to lubricate the lawn mower before storing it for the winter, and also as needed when the parts make such a “request”. A few nuances in the procedure:
- there is no need to lubricate the rod, since the shaft itself is lubricated, which rotates inside the part and part of the product remains on its inner walls;
- every braid needs lubrication, without exception, and the instructions for the tool will tell you about the amount of lubrication;
- Do not forget that the trimmer also has an upper gearbox, which also needs to be lubricated;
- the shaft is lubricated by filling small channels at its end, because they are in contact with the gears located inside the gearbox;
- How to lubricate a lawn mower - choose a special product in the specialized KosiKosa store, and then your tool will always be functional and free from overheating.
Gearbox lubricant appears in the service catalog as a separate product. Order it at a low cost and ensure long-lasting operation for your gearbox!

Why choose the FS 55 brush cutter
If you still don’t know which model of the described equipment to choose, then you should read reviews about the Shtil FS 55 lawn mower. After reading them, you can understand that consumers identify many reasons that made them lean towards the described model. For example, instead of a strap, the manufacturer provided the device with a belt. This allows you to distribute the load from the device across your entire back. Otherwise the weight would be concentrated on only one shoulder. With this placement option, even after very long work there is no back pain.
Buyers also like the bicycle handle, which increases ease of control. When working, your hands will be spread wide apart, so it is easier to control the unit. It is very maneuverable. Buyers like that the handle and belt can be adjusted to suit the operator's needs.
The tool can be easily adjusted for comfortable use. The controls are located on one handle. There is no need to reach anywhere, everything is located under the palm of your hand. The Shtil FS 55 petrol mower, according to consumers, is also convenient because it has a pair of protective covers, one of which is installed for the knife, while the other is for the fishing line. The casing for the latter has a narrowing at the rod.
The trimmer has a head that is clearly visible and allows you to handle tight spots. The escape of stones from under the knife will be prevented thanks to a special casing. This helps protect the operator. Using the existing primer, you can pump fuel into the carburetor. Even after a long period of inactivity, as consumer reviews indicate, the lawn mower is quite easy to start. Engine starting is made easier thanks to a special easy start system. As home craftsmen emphasize, you no longer have to waste energy on pulling the cord for a long time, because for this you will need to make 2 jerks.
Removing the handle
Direct disassembly of the Shtil 180 begins with removing the handle, which is attached to the chainsaw body using three rubber shock absorbers. To remove it, you need to remove the plastic plugs from the internal cavity of the shock absorbers, then using a powerful screwdriver, first press out the upper shock absorber, then the one closer to the rear handle.
At the rear of the handle there is a throttle trigger, which is connected to the carburetor through a wire rod; in order to disconnect the rod from the gas trigger, you need to unscrew two screws and disassemble the handle.
When the handle remains on one shock absorber, you need to unscrew the chainsaw body from the inside of the handle and, bending it to the side, remove the body from the last rubber band.
