How to grease a trimmer bearing for Viking grass. The first launch of the cultivator
Lubricant for a trimmer gearbox for grass. Than and how to lubricate?
Removing waste oil is the first step in servicing the gearbox. You need to remove the old layer for several reasons:
- Worked out oil cannot perform its functions;
- Contains small particles formed by wear of grated elements;
- Old oil will be mixed with a new one, because of this, the assembly will not work properly, the replacement will not bring any results.
Waste removal is carried out using disposable paper towels, rags, or using a piece of fabric at hand. The removed parts of the gearbox should be thoroughly washed in the solvent or gasoline and dried before installation. Residues used to clean materials can also mix with new oil and change its consistency, which will lead to a decrease in performance.
Gear lubrication step
The gearbox should be filled with such an amount of oil so that it completely covers the gear.
The adequacy of the lubrication of the angular grinding machine is controlled by short.term inclusion of a grinding machine. If after 3-5 minutes of operation the temperature of the node increased and the oil leaks, part of its volume should be removed. For this, the gearbox is dismantled again, excess is removed by a rag or rag.
During the inspection, the opposite situation may occur when the noise is generated when the angular grinding machine is turned on. This means that fat is not enough and it needs to be added.
When using a grinding machine, it is necessary to periodically check the correspondence of the oil elements of the gearbox, the quality of the available oil.
On mowers with a drive to a trimmer with work nozzles, a transitional conical gearbox is provided. The transmission of torque occurs through conical genees. This type of gearbox is produced by two types: serviced and supportive. The name is served. the gearbox received from the possibility of adding lubrication to the working cavity for lubricating gears. If the gearbox is not served, then the lubricant is laid by the plant.the manufacturer for the entire service life, and the gearbox itself has a sealed case. According to the developers of the manufacturer, such measures increase the service life of the gearbox, so-as contaminants do not get inside through the non-density of the lubricant. The reducer of the lawn mower is the most loaded part that transfers the force with a change in direction, so the node is very important for the correct care and proper lubrication, what lubricant is needed for the gearbox and the repair of the conical gearbox C = with replacement bearings can be watched by watching a video below.
Stihl lawn mowers are well.deserved popularity
STIHL motokos differ in class, engine type and purpose. Designed for caring for small areas to cleaning large territories from thickets of weeds of shrub and young trees. In this regard, it is customary to divide them into classes. The first class includes amateur vehicles of small power up to 1.2l.With. By design, amateur braids for grass “Stihl” are produced with a curved bar. which allows the lower conical gearbox to exclude from the structure, which significantly reduces the cost of the cost and maintenance. The lawn mower with a curved bar is designed to work with a cutting tool from fishing line or polymer knives. It is convenient to use them in garden areas with small areas.
The second class belong to universal medium.power units up to 2.2 liters.With., intended for field and landscape work. In such designs, a straight hard shaft is used, which allows you to equip this class with saw steel knives for nozzles with help which can be cut down by shrubs and small trees. The design provides for a conical served gearbox. What lubricant to use for the reducer of the lawn mower. A special, under the brand name is the name “stihl” or ordinary lubrication of lip.
Engines from 6.3 to 8 liters.C is intended for professional use in forest or horticultural farms. The name of them is black cutters, these are the most powerful motorcycles for working in large areas, cutting small shrubs and trees. In the arsenal of a working tool there are saw wheels for cleaning bushes with a diameter up to 7cm. Bigorezes are equipped with an anti.vibration system, thanks to which working with such a tool becomes more comfortable. What lubricant to lubricate the gearbox of the lawn mower with powerful drive mechanisms, the lubrication of the Reducer of the Stihl lawn mower is carried out by a special proprietary or grease “STIHL” or production of Litol 24.
DIY REPAIR OF VIKING
Details: DIY Returns from this Master for Olenord Law.com.
Active operation of garden equipment leads to a quick failure of individual nodes or parts. It is not necessary to dispose of the technique, since it can still be useful in the future. After all, after sometimes carrying out a small repair of the lawn mower with your own hands, you can return it to the previous working state.
Depending on the area of the lawn and the growth of grass on it, the owners choose the optimal technique in characteristics. It is several types:
The average mower stands in the climatic conditions of St. Petersburg, or similar regions about four seasons. expensive or less operated garden assistants are able to withstand in the field of 5-6 seasons.
Also, the restoration of lawn mowers with your own hands will be required if the conditions of winter storage are inappropriate. For example, after use, there were no cleaning surfaces or there was no off.season preventive maintenance. As a result, various problems are manifested:
- frequent sharpening of the lamp of the lawn mower is required;
- just does not start a lawn mower;
- The motor starts up, but through a short gap the lawn mower stalls;
- malfunctions of the carburetor appear, which requires not only disassembly, but also cleaning with repair;
- Do.it.yourself renovation of the lawn mower is required with a significant reduction in power during operation.
You should not go to an expensive service center. Many problems can be solved with minimal costs and repairs on your own.
After each use of the tool, it is necessary to clean the cutting elements. Change the oil regularly and perform a minimum risk.
Mowers, inside of which electric motors are located, most often begin to be capricious due to oxidation of contacts. The terminals are covered with a layer of scale from excess humidity in the room or in another place of storage. It is also worth checking the absence of a break in wires in problem areas. For this operation, a multimeter or other tester type is used.
When a set of garden equipment contains a brush engine, we identify the performance. Brushes can wear out quickly, leading to a lack of contact. The reptity of them costs relatively little, and it is easy to find it in specialized stores, where they sell spare parts for such a technique.
Asynchronous engines are also in wait for the malfunctions. They refuse phase.drive capacitors. A similar situation is diagnosed at home is problematic. It can be detected by indirect symptoms:
- The sound of a buzz is heard;
- When starting, the case twitches slightly;
- significant heating of the motor occurs even at a slight load;
- Reduces are reduced.
It is worth diagnosing the condition on the tolerance/button and the voltage supply to the electric motor. Когда проведено тестирование описанных узлов, а нарушений в работоспособности не обнаружено, то вряд ли удастся исправить поломку газонокосилки своими руками. Then you will have to use the services of the corporate service.
Primary diagnosis is carried out from the stage of elimination of the most obvious breakdowns. When the motor does not start, it is worth monitoring the presence of fuel in the tank. If there are its remnants from last season, then it is worth replacing it. Low.quality gasoline after wintering is able to lose its characteristics, give an undesirable sediment or even stratifying at a fraction in density. In this form, he is not able to start the engine, but only clogs the system.
At the second stage, we find out why the spark does not appear. Its loss will not make it possible to ignite the fuel. Remove the cap from the candle and unscrew it from the planting nest by a special clip that came with a mower. Next, we throw the cap to the candle, bring it closer to the threaded part or the metal element of the motor, and at this time the partner pulls the starter.
With such manipulations, a blue powerful spark is required to appear in the working node. She will be able to notice her even in daylight. It is important to test this next to the unpainted metal part of the engine that can conduct current.
When there is no spark, you need to go for a new candle to the store. Do not return to the motor even with a weak or unstable spark. It is better to clean the working contacts from the haze on the head.
During operation, the occurrence of rattling in the design is possible. It at first does not affect the performance of the mechanism as a whole. However, it can lead to unbalancing and increased noise during operation. It is worth tightening the fasteners on the frame in a timely manner.
Tightening fasteners on the frame
An uneven slice of grass is evidence that you need to sharpen a lawn mowing knife. It’s not so difficult to get to them, but it is important to completely turn off the equipment from power. You can work on your own using tisses and files or on a solid sandpaper. It is important to ensure the cut angle uniform throughout the line 30 degrees. If there are excellent sections in the surface, then this is evidence of getting on a solid surface. Replacing them will cost quite expensive.
After turning on, a whistling sound appears. An unpleasant acoustic effect is associated with the penetration of foreign elements inside the design. They can block the video in the aerator. You can solve the problem with disconnecting a blocked roller and subsequent extraction of an extraneous subject.
The engine of gasoline equipment becomes almost immediately after the start of short operation. The culprits are a jammed crankshaft or a piston. In parallel, we check the presence of oil in the crankcase. On the disconnected engine, manually start the rotation or add the oil as necessary. However, in such a situation, you often have to apply for recovery to specialists.
Attachments and spare parts
Thanks to a wide selection of attached additions, you can expand the functionality of the devices. Freak is necessarily included in the standard base kit. Usually there are from 4 to 6 pieces. You can always buy details and thereby improve the quality of soil processing. Viking ABS 400, AHV 600, AEM 500 units even specifically provide for the possibility of adding mills.
For planting potatoes, add.ons called “digging” and “soot”. Models of this spare part are found on sale under the AKR 600 series. It is suitable for equipping all Viking modifications. It is also allowed to use the addition of manufacturers Pubert, Robix, Solo.
Enchanting can be done with the cultivators of the VH 400, 440, 540, 660, HB 560, 585, 685 series. Suitable cigns: Viking Abu 440, 500, AHK 701. The tool allows you to not only spill row spacing, but also cut the furrows, loosen the soil.
Weeding the aisles with a cultivator is possible in the presence of a plane cutter. This device is distinguished in width: from 24 to 70 cm. Devices are allowed to combine or use one. Combination is possible with the identity of the unit mounting units and additions.
For Viking cultivators, plows of the same manufacturer produced under the designations ADP 600, AWP 600 are provided. The first option is revolutionary, and the second is a semi.turn. The choice of this or that equipment is determined by the quality of soils. For example, the clogs of the revolving provide optimal deep plowing and loosening. Expanded species are capable of plowing more land. Pre.sowing semi.turn plow provides high.quality weed removal and harrowing of the earth.
With the most part of Viking cultivators, you can use soil.spaceds of various brands. Equipment from the manufacturer in some cases is not a mandatory component of quality. You can choose universal sets of wheels, howling, coupling and other spare parts, which can improve the operation of the units.
The operating instructions do not provide for the use of hinged parts from heavy motoblocks with light cultivators. This rule should not especially be violated by people without appropriate skills and knowledge of the device of motorcycle equipment.
Cultivator device with a worm gearbox
The longest service of any equipment will provide good care. This event is especially important for a spare part as a gearbox. This complex mechanism is a complex part of all types of motor vehicles. The gearbox consists of gears or worm wheels that provide rotation of the shaft of the power unit. The design of the product includes many mechanisms that provide movement.
The worm gearbox is installed in the cultivators of small and medium power. Options used in Vikings, four.set. This factor is associated with the number of thread channels on the screw. Engineers of the Austrian company came up with such screws from a durable cast.iron alloy. Many other companies offering cheaper cultivators use inexpensive steel for this detail, which reduces the cost of products.
The worm device takes torque from the engine and launches the process of rotation of the last. If such a gearbox is installed on the cultivator, the unit will differ:
GREASING OUT THE BRUSH CUTTER PARTS
For a long service of the entire cultivator, it is important to pay the attention of this detail, for example, to engage in periodic lubrication of the element. Correction of the worm reducer can be carried out independently, but you need to familiarize yourself with its schematic image. The worm device is simply disassembled, so it is available for independent repair.
For example, a common cause of excessive noise emanating from the device during operation may be the insufficiency of oil in the carburetor. Noises arise in the gearbox. It is recommended to pour oil into it to the optimal level. Иногда при его достаточном количестве проблему с излишней шумностью устраняет замена масла на другую марку. Perhaps the unit got fuel of dubious quality.
From the gearbox of the cultivator, you need to drain the old liquid. This procedure is carried out through the lower drain hole, which is usually closed by a plug. It must be unscrewed, after installing a suitable container below. You need to wait for all the oil it will flow out, and fasten the cork back with tightening to the stop using the key.
A funnel is installed in the bulk hole that is located on top. Next, a suitable lubricant is poured to the desired level. It is checked by a trial with a probe, which is screwed into place, and then is removed again.
The rules suggest the planned oil replacement in the Viking gearboxes every 100 hours of operation.
Viking TE-600 is a device with high power and small mass. The tool is used for sections of small area.
The device copes with the design of the edge of the lawn, sprinkles grass near the walls of buildings and at home.
The device is equipped with a limiter of the length of the electrical wire, which prevents a sudden power outage. The operator can adjust the handle in height. If you install hinged blocks instead of the handle, then the tool can be used as garden scissors for cutting branches of trees and bushes. The engine is equipped with a system of protection against overload.
- The engine has a power of 0.54 kW.
- The width of the cutting zone 350 mm.
- Noise level is 96 dB.
- Table head of the TAP N GO brand.
- Mass 4 kg.
The coil is automatically wound with the adjustment of the double thread of the trimmer head by means of pressure on the coil.
We carry out the winding of the fishing line
Sentlessly completed disassembly of a spray coil without losing its spare parts allows you to go to the main task-winding into a fishing line coil. Technological features of the design of the spool and the number of working antennae determine the sequence of actions.
Coil with one working osik
The easiest option and a simple sequence of actions:
- The dimensions of the bobbin and the length of the original factory winding determine the length of the fishing line recommended for winding. 2 5 m.
- One end of the fishing line is inserted into the fixing technological hole located inside the spool.
- The fishing line for the trimmer is wound on the drum in reverse rotation of the spray in the trimmer product direction. as a rule, on the inside of the bobin, the arrow indicates which direction the winding is carried out.
- A small section of the fishing line is left free to output it. it is fixed in a specialized border on the inside of the bobbin, designed to keep the winding when assembling a spool in working condition.
- The left end of the fishing line is passed through the hole of the outer part of the bobbin.
- Half of the bobbin are collected and put on the bar of the trimmer device.
Two working antennae
In this type of spools, the number of grooves for winding the fishing line lying on the inside of the coil should be determined:
For both cases, a fishing line for a trimmer 2-3 m long is taken. In a single.captable coils, the fishing line for a trimmer stretches into a through hole, its ends (antennae) are folded together and aligned, after which they are wound in the back of the rotation of the bobbin on the bar the side. inside the arrow is usually indicated the correct direction of the winding. In the presence of fixing grooves, the ends of the fishing line are threaded in them or hold their free arm fingers, spread into the through hole of the outer half of the bobin, the spool is closed and attached to the bar of the trimmer product.
The difference between the winding of the fishing line in the two-to-dancing coils is that initially a line of fishing line 2-5 m long is folded in half (to determine the middle fold), and the bend loop is inserted into a special groove between the grooves. Both strains of the fishing line are wound each in its own groove, fixing the antennae and assembly of the coil is similar to the option considered above with one groove.
The first implementation of this procedure may seem long and quite time.consuming, but over time and experience, this task will be solved much faster and easier.
The video below will clearly show how to refuel a fishing line for a trimmer to the coil of a trimmer for the grass and correct it correctly. this operation is not a complicated one and, with some patience, will necessarily be crowned with success:
How typical mechanical defects and ways to eliminate them with your own hands are manifested
The following damage to the kinematic scheme most often occurs on the electrimmer:
- the bearings of the electric motor are cleaned or spoiled;
- The fishing line for the trimmer is tangled or broken due to incorrect winding to the coil;
- The torque from the engine to the mowing head is not transmitted;
- The plastic case and individual parts melts when overheating due to increased loads;
- enhanced vibration of a rotating head is created, which makes the kosbu.
How easy to check the work of bearings
It is enough to update the external clip regarding the shaft and immediately with tactile sensations of the fingers to evaluate the smoothness of their work, the state of backlash.
Broken and worn bearings must be replaced. Do not forget to update the grease if necessary: remove the stream and apply a new.
How to prevent malfunctions of a mowing head associated with the commission of typical mistakes by home “craftsmen”
Trimmer heads are created by three types of structures, implying the issuance of fishing line in one of the ways:
The overwhelming number of products uses semi.automatic fishing line. It also allows a manual regime for adjusting the length of the cutting area.
A large number of breakdowns are associated with a violation of the operating rules recommended by the manufacturer, when a trimmer for grass begins to work outside of its capabilities. These include:
- a significant excess of the diameter of the cutting fishing line leading to an increased load on the engine, intermediate shafts, gearbox and mechanical parts of the head;
- installation of homemade knives or chains instead of standard structures;
- Incorrect winding of the fishing line.
Such are the homemade like “eternal fishing line for a trimmer for grass” not only damage the kinematics of the lawn mower, but also injure people, causing harm to their health. I do not advise doing this to do. There is no economy here.
How easy it is to wind a fishing line for a trimmer on a spool
Usually this issue is difficult for beginners. Especially for this case, I made a narrative on my channel Yandex Zen.
The engine works, but the spitter head does not rotate: what’s the reason
The breakdown is associated with the cessation of the transmission of the torque of the engine to the working body. A defect can occur anywhere in the gear. Most often, in models with the gearbox, the reason lies in the wear of the working faces of the gear.
over, if the teeth on one are worn out, then both must be changed at once, because the second also suffered.
The fact is that the design of the trimmer gearbox body is not completely tight. Otherwise, its cost will increase strongly. Gears should always work in lubrication, and it is consumed. If it is not replenished, then the breakdowns are inevitable, which happens quite often.
In cheaper structures without a gearbox, a coil of the coil is fixed through a plastic sleeve to the shaft. During constant loads, plastic heats, and the sleeve wears out during operation, the head begins to hang out.
When the critical value of the backlash is reached, the sleeve must be replaced.
Why can the lower part of the composite rod
The reason for increasing temperature in this place can only be strong friction of rotating parts about fixed parts. In other words. the spring shaft is tightly pressed against the walls of the plastic insert. (See above the photo of the details of the composite bar).
This leads to melting the plastic up to damage to the sleeve and the formation of a continuous lump from it, penetrating the boots of the shaft.
When cooling in the air, a monolithic structure is created, which can block rotation and even jam the engine.
Timely perform preventive examinations and work.
What is the overheating of the case
Owners of light trimmers often use their mowers at the limit of their capabilities, or even create unacceptable operating conditions for them. The result of such an attitude we have a burned.out electric motor and molten plastic of the case.
Such defects are not eliminated with their own hands and require a complete replacement, which is comparable at the price of buying a new unit.
Why is there increased vibration and how to get rid of it
We understand that any well.balanced part regarding the axis of rotation does not create vibration. Beats arise where the factory balance is broken or there is a marriage.
The mowing head has a fairly large mass. Therefore, it is often the cause of increased vibrations, but in each case it is necessary to study this issue on a specific design.
The owner of a short Masterlom video, Masterlom, shares his experience in eliminating such a defect on the Tekhmann DCE-2014B electrician. His achievements and ideas can be useful to you in eliminating vibrations. I recommend to see.
However, vibration can create the lack of lubrication on the spring shaft when rotating due to friction against the wall of the composite bar. Consider this question too.
Finishing the presentation of the material, I note that I tried to tell everything that I know about the repair of the electrimmer with my own hands. The experience of its operation exceeds five years.
If you have met other defects or you know more effective ways to eliminate them, then write in the Комментарии и мнения владельцев. Your knowledge will be useful to other readers of my electrician blog.
In order to better understand what lubricant is needed for your trimmer for grass, you need to figure out how the gearbox works, what components it consists of and analyze the working conditions of these nodes.
The trimmer gearbox for grass is usually located at the lower end of the drive shaft and serves for two main tasks:
- Transmission of the rotational movement of this shaft Bobin with a fishing line or a mill
- Increasing the torque of motorcycles by reducing the number of revolutions
Typically, the gearbox consists of the body itself, shafts, several bearings, one or more cylindrical and conical gears, seals (see. a photo).
The drive shaft at high speed is rotated by the leading shaft with the lead gear. The driven gear has more teeth and therefore the driven shaft rotates slower. But the torque is increasing on it. Each shaft is installed in the housing on two bearings.
When the trimmer for the grass for the gearbox, vibrations and shocks associated with a change in resistance to rotation from the interaction of the cutting node with grass, and shrubs are transmitted. Grass or dirt sticking to knives also with a high constantly changing speed of rotation contribute to the occurrence of dynamic vibrations and vibrations.
In general, we can say that the reducer nodes operate at a high speed of rotation and dynamic loads. At the same time, high contact voltages occur on the teeth of the gears, bearings experience transverse vibrations.
Temperature regimes are medium, since the tool is designed to mow grass, and this work is usually performed in the summer, at positive temperatures. As a result of friction, the nodes of the gearbox are heated, but excessive heat is removed by the lubrication and cooling of the gearbox body with atmospheric air.
Strong heating is a phenomenon uncharacteristic for the gearbox and indicates the need to repair the node or its lubrication.
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.
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.
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.
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.
Gear lubrication of a trimmer for grass
Lubrication of gears must be carried out regularly in accordance with the recommendations set forth in the operational instructions of the model used. You need to do this also if:
In addition to the gearbox, it is also necessary to regularly lubricate the shaft of a trimmer for grass. This is the norm of proper care of the device.
With the constant use of a trimmer for grass, its gear mechanism experiences a load from grass, dirt sticking on knives, or due to a change in torque. Lubricants must be selected high.quality to extend the service life of the gearbox.
Used types of lubrication
When choosing lubrication, it is necessary to take into account the following factors:
Famous manufacturers, for example, STIHL, Husqvarna and others, in addition to trimmers, produce lubrication for them. Such products not only reduces wear, but also protects the metal of gears from corrosion. Therefore, for motorcycle from these brands, it is better to use their lubricants.
If the composition used for lubrication has good adhesion, then it is practically not squeezed out of the gearbox through the gaps.
For different models, lubrication is consumed in different ways. This is determined largely by the intensity of the use of motorcycles and heating the transmission mechanism. It is believed that the lubricant is enough if the temperature of the gearbox during operation does not exceed 40 ° C.
By consistency, lubricants for a trimmer for grass can be:
In terms of composition, the following types of lubricants are in demand:
- graphite, significantly reducing friction, as a result of which the rotation of the gear improves;
- lithium, which are also an excellent anti.corrosion composition, saturated with increasing the wear resistance of metal with additives without harmful substances;
- universal, containing high.degree mineral oils and improving operational characteristics components.
An example of suitable lubricants are: Champion EP-0, Gear Grease Oregon, Oleo-Mas, Azmol 158, Litol.24. You should also pay attention to the advice of manufacturers on this issue and use the materials they offer. You can buy them at specialized retail outlets.
A lubricant Champion EP-0 Universal 120 gr
The algorithm for self.lubrication of the gearbox
To make lubrication of the gear ratio, its preliminary disassembly is not needed. A special hole for these purposes has already been laid in the device (it is shown in the photo below). In addition to gears, when lubrication, you need to pay attention to such elements of the mechanism:
Pour oil or apply solid grease through a tavniper closed by a screw. At the same time, they perform actions in the following sequence:
- The gearbox body is cleaned of dirt and adhering grass, especially thoroughly the plot around the plug so that the garbage does not get inside the mechanism;
- Using the appropriate tool (often it comes with a trimmer), the cork is unscrewed;
- The selected lubricant is introduced from the tube into the open technological hole, or using the syringe, as shown in the photo further;
- screw the cork in place.
When making lubrication, you need to rotate the knife so that it is evenly distributed through the teeth of 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 and housing, shaft, and only then use the new. The disassembled mechanism is conveniently lubricated with solid compositions.
The entire reducer lubrication process is demonstrated in the video:
Lubricating the gear node is required at least once during the year, but it is recommended to do this every 20 hours of intensive use of motorcycles. If the first signs of malfunctions with the mechanism appear, then you need to make lubricants as quickly as possible.
How to replace a trimmer gearbox for grass: an algorithm of action
To replace the gearbox with a similar part from the same manufacturer, it must first be disassembled and removed from the bar. At the same time, they act according to the following algorithm:
- weaken the fitting bolts located under the transfer mechanism;
- Using round.drawers, remove two corkscrew rings;
- Applying the puller, pull the bearings from the driven and the leading shafts;
- Then collect the mechanism, in the reverse order by installing all spare parts.
The disassembled transmission mechanism is shown in the photo below.
If the puller is not at hand, then you can try to gently knock down the bearings. When they have stuck and do not move at all, you can heat them using an industrial hair dryer (at a temperature of 600 ° C) and remove.
Collecting a gear node is easier than disassemble it. Only a light tapping with a hammer for planting parts in place may be needed. After assembly, it is imperative to check that the driven shaft turns out by hand.
Когда есть необходимость замены передаточного узла неоригинальной деталью, тогда следует учитывать их взаимозаменяемость. At the same time, it should be taken into account:
- the diameter of the bar (this parameter often is 25.4 or 26 mm);
- The parameters of the drive shaft. the shape of the docking space and the diameter (its common value is 8 mm);
- option of consolidation of protection.
If the considered parameters coincide, then it will be possible to set a part from other models.
Timely lubrication of the gearbox will ensure its prolonged operation without repairs. In addition, modern materials protect the metal from corrosion well, increase its wear resistance. When choosing, preference should be given a lubricant recommended by the manufacturer of the operated trimmer for grass. If such compositions are not possible to purchase, then the analogs considered or other suitable in properties should be applied. When it is necessary to disassemble the mechanism during the repair, this should be done carefully so as not to damage individual parts.
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 consumption of the lubricant also depends on the temperature at which it retains its lubricant. When heating the gearbox to 40 ° C, it is believed that its working conditions are satisfactory, and there are enough lubricants.
Pawn Stars Has Officially Ended After This Happened
It is believed that there is no universal lubricant for the gearbox for grass, but this is not entirely. In fact, a suitable lubricant will be the one in which the following components are present:
- Anti.sympathetic supplements, which include toxic lead;
- Solid lubricants with the presence of graphite or disulfide of molybdenum (the latter is preferable, since the lubricant is completely preserved for the large range of the speed of the shaft);
- Only mineral (inorganic!) oils, with a high degree of cleaning.
The mentioned requirements are fully met by Gear Grease Oregon or Champion EP-0, domestic compositions Oleo-Mas, Litol.24, or Ammol 158, as well as those recommended by the manufacturer of a particular model of a trimmer for grass.
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.
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.
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.
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.
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.
