What kind of oil can be used for trimmer

Buying any kind of equipment is a kind of lottery, but a lot also depends on the gardener. In caring hands, and Chinese samples serve for a long time and do not fail their masters at the wrong time. And if you forget on time grease gear lawn mowers, do not clean filters, use cheap low-quality gasoline, then garden equipment from the most famous brands will become a headache.

Lubrication of the lawn mowing gearbox is one of the most important elements of the maintenance of the gas trimmer, which must be carried out directly by the user.

Time and procedure for gearbox prevention

I recommend that you necessarily carry out the prophylaxis of a new gas trimmer immediately after purchase, with the addition of lubricant to the gearbox. Despite the high cost of gardening equipment, some manufacturers save and put grease only at a minimum, at the time of break-in.

How often to lubricate the lawn mowing gear

Often, a routine inspection of the transmission with the addition of liquid grease is carried out once a year at the beginning or end of the season. If the gas trimmer is not used by you in professional volumes, this is enough.

For large mowing volumes, it is necessary to lubricate the lawn mowing gearbox every 20-50 hours of operation. If the operating conditions of the garden equipment are difficult, for example, a large field is mowed at a time, and the lawn mower does not have time to cool down, or cheap lubricants are used, then the grease must be checked and added every 20 hours of operation.

Indirect evidence that it is necessary to lubricate the gearbox may be overheating or increased unit noise.

Also, a complete replacement of the lubricant, with disassembly and washing of the unit, I recommend when buying a used gasoline trimmer.

Grease for gas trimmer gearbox

Assortment of lubricants for gardening equipment

According to the instructions, a special transmission fluid grease should be used to lubricate the bevel gear. As a rule, gardening equipment manufacturers produce and recommend the chemistry of their brand as the most adapted to their devices.

At the same time, in order to reduce the cost of operating garden equipment and increase the attractiveness of the auto chemical brand, grease for garden equipment is usually produced multifunctional. It is intended not only for the lubrication of gearboxes of gasoline trimmers, but also for the processing of hoses, gears and gearboxes of any garden equipment and mechanical devices operating under high loads.

This gear lubricant is sold in tubes convenient for use and subsequent storage.

Even if the specialized lubricant for the gearbox was almost completely developed during operation, the additives still create an effective lubricating protective film on the surface of the gears.

It should be noted that many owners of lawn mowers in the former CIS expanses use conventional Litol-24 or lithium-based grease for lubricating the gearbox. It is convenient to refuel the gearbox with a 5-cc medical syringe.

Many motorists, instead of the side screw, pick up the threads and screw the grease fitting from the cars that have served their crosspieces. This refinement allows the addition of Litol without disassembling the assembly using a grease gun.

An undoubted advantage of using Litol and lithium-based grease for refueling lawn mowing gears is the reduction in cost of operation. But there are nuances due to which spears break on forums of gardeners of Internet space. My thoughts are on what can be lubricated with lithium-based lubricants and what is not, read in the article “Litol as a grease for a lawn-mowing gearbox”.

How to grease a lawn mowing gear, gas trimmer

17 side bolt on gas trimmer gearbox

For safety reasons, in order to avoid accidental start-up, all preventive work on the lawn mower must be carried out with the electric cap / plug removed from the candle. Do not turn the trimmer over to avoid gas leaking.

We unscrew the side screw on the lawn mowing gear. Depending on the manufacturer of the garden tool, a turn-key bolt may be used instead of a hexagon screw, usually by 17. The thread is normal, turn off counterclockwise. Do not lose the sealing washer.

Add specialized grease

If no grease is visible on the inside of the screw, add 3-4 grams. Turn the gear by hand, changing the direction of rotation so that the grease is distributed over the gears.

Repeat the operation several times. On average, about 5 to 10 g is included in the gearbox. The assembly must be completely filled with grease, taking into account the installation of the screw.

Then reinstall the screw by tightening it firmly.

As you can see, it will not take a lot of time or special skills to lubricate the gearbox on the lawn mower. Usually, we’re going to take longer than we do the entire amount of preventive work. Reliable to you garden equipment. Share your experience with petrol trimmers in the comments.

How to Oil the Trimmer Reducer

From time to time, in the midst of intense work on mowing the grass stand, your trimmer begins to make nasty, grinding sounds. It complains about the lack of lubrication gearbox. a more actively loaded device node. And soon these “warnings” may be followed by jamming of the drive.

What lubricant should be used for trimmer gear?

During operation, the mechanical part of the trimmer is loaded with contact forces on the teeth, resistance reactions from adhering weed (from time to time with a grease), dynamic, impact loads due to a constantly changing torque. Grease for trimmer gear must fully take into account these features, because the selection of the brand must be strictly personal.

The following reasons are taken into account:

  1. Brand of the manufacturer. Any trademark is not unreasonably oriented on lubricants of its own production (there is an option to talk about cheap Chinese products later). This applies to such manufacturers as Husqvarna, Stihl, Huter, Makita, etc. The exception is Russian-made trimmers: nettle, Caliber in the user’s annotation generally does not show the brand of lubricant.
  2. The viscosity of the lubricant. As everyone knows what remains to be done for our client, the lubricating compositions are divided into three groups. highly viscous (colloidal allowing accounting (software) containing various additives), universal universal plastic compounds and solid lubricants softened during operation.
  3. Not bad adhesion to the surface of the gear parts during busy> the grease is not squeezed into the gaps or out of the assembly.
  4. Intensity of lubrication with a gearbox. Here you have to rely on your experience and the advice of professionals, since some domestic manufacturers of trimmers, relying on the availability of their own service centers, generally do not give clear advice on the period of operation of the gearbox between 2 lubrications.

What kind of oil to lubricate the trimmer gear

Zmazuvannya reduktіv і lawn mowing shaft

It is believed that there is no universal lubricant for the trimmer gear, but this is not entirely true. In fact, a suitable lubricant will be one in which the following components are present:

  • Antiwear additives, which contain no toxic lead;
  • Solid lubricants with the presence of graphite or molybdenum disulfide (the latter is better, because with all this, the lubricity is completely preserved for a huge range of shaft revolutions);
  • Only mineral (inorganic!) Oils, with the highest degree of purification.

The above requirements are fully met by Gear Grease OREGON lithium greases according to another Champion EP-0, Russian compositions Oleo-Mas, Litol. 24, or Azmol 158, also those recommended by the manufacturer of a particular model trimmer.

how grease gearbox trimmers?

At the top of the casing, where the gear block is installed, there is a technological hole, which during operation of the trimmer is plugged with a screw. This rumor has it that the screw is loosened, and 1.5. 2 ml of grease is introduced into the hole using the nozzle on the tube. If the grease was purchased in a different packaging, then for this operation a mundane, single syringe honey is suitable.

Then the screw is installed in its original place. This function, regardless of the user’s advice, should be done every 10. 15 hours of operation of the trimmer in operating mode.

Other reasons for updating, as it is also called changing gearbox lubrication, are independent performance of small routine maintenance (for example, cleaning and washing gears of a gearbox before summer), repair of a unit, preservation of a trimmer for a period of cold weather, etc.

If the gear unit is disassembled, it is recommended to completely remove the remains of the previous grease from the surface of the parts, even if it does not have any signs of oxidation and contamination. And only then apply new grease. After applying the lubricant, it is recommended to rotate the shaft manually a couple of times, and make sure that the lubricant is moderately distributed over all parts of the gearbox.

When lubricating, increased attention is paid to the following elements:

Trimmer Gear Lubrication: Selection Criteria

During operation of the gasoline trimmer, the gearbox begins to make grinding sounds, which are a sign of lack of lubrication, or loss of its properties.

Of course, the owner may not attach much importance to extraneous noise, but ignoring them will lead to jamming of the gears and, as a result, the upcoming expensive repair.

Therefore, in order to avoid the prerequisites for the occurrence of grinding, it is necessary to comply with the lubrication regulations of the trimmer gearbox recommended by the manufacturer.

Trimmer gear device

Regardless of the manufacturer or model, the modern trimmer is equipped with a gearbox to change the angle of transmission of mechanical energy between the drive shaft and the fishing line head.

Bevel gears are most widely used in lawn mowers, because, unlike spur gears, helical gears can bear enormous speeds, have smoother engagement and have increased bearing capacity.

The main parts of the trimmer gear

In the duralumin housing (1) there is a pinion shaft (2) and a bevel gear (3), pressed onto the driven shaft (4). To reduce the friction forces during rotation, rolling bearings (5) are installed on the bearing points of the shafts.

Therefore, in addition to the main components listed above, the trimmer gearbox includes a special hole through which bearings and gears can be lubricated without disassembling the assembly.

Grease for trimmer gear: which one to choose?

Gear paste selection

Currently, the market for gasoline powered tools and supplies has a wide selection of greases that are designed to reduce friction and overheating of rubbing parts.

Therefore, each owner, when the time comes for maintenance, is faced with a problem than to lubricate the trimmer gear for long-term operation.

For these purposes, special plastic pastes are used, which vary in properties and manufacturer.

Grease for famous brands of trimmers

Each brand of gasoline trimmers always recommends lubricant for the lawn-mowing gearbox of its own production.

  • Husqvarna. This Swedish manufacturer recommends the use of Multi-Purpose Grease Grasa Universal grease. This material is available in tubes of blue and black in volume of 225 or 250 grams. According to the company, this trimmer gearbox grease was developed specifically for the Husqvarna technique, taking into account the steels used and the operating speeds.
  • Stihl. For the Stihl FS Series lawn mowers, the manufacturer recommends using Stihl Superlub FS gear lubricant, available in 225 gram tubes or disposable containers of 80 grams in silver-orange.
  • Patriot. Lawnmowers of this brand are recommended to be serviced by the original Arsenal lithium grease of the AR-417 brand. It is specifically designed for geared gears operating at high speeds and temperatures.
  • Huter. For the conical transmission of the tool models of this Huter company, you can use any of the above brands of gear lubricants, as well as universal types of Rezoil, TsIATIM and others.
  • Champion. Champion Lawn Mowers User Manual recommends CHAMPION Super-Lube EP-O for recommended lubricants. The material is delivered in a 250 gram jar or in a disposable nipple Premium Champion C1104.
  • Makita. This Japanese manufacturer advises its customers to use Makita branded grease, which comes in white tubes with a red cap of 65 ml and 80 ml.

Lawnmower Gearbox Grease Selection Factors

Often the owner of a particular brand of gas trimmer does not have the opportunity to purchase a lubricant recommended by the manufacturer for any reason. In such cases, you will need to search for an analogue, which in its properties will be identical to the branded paste. Therefore, when choosing a paste for a lawn mowing gearbox, you should pay attention to the following factors:

Lawn mowing gear lubrication

  1. The viscosity of the lubricant. All pastes on the market are divided into three main groups, namely: highly viscous (contain additives), solid lubricants (soften during operation of the unit) and universal plastic compounds.
  2. Intensity of lubricant consumption. This factor is taken into account based on the personal experience of the owner, and is characterized by a period between two lubrications. Most manufacturers regulate servicing the gearbox every 20-40 hours of operation.
  3. The degree of adhesion to the parts of the gearbox. This indicator is characterized by the adhesion of grease to the metal trimmer assembly.

How to lubricate the trimmer gear

Disassembled lawn mowing gear

Almost every lawn-mowing gearbox is equipped with a small technological hole, which is plugged with a special bolt during operation.

After thoroughly cleaning the unit of grass and debris residues, it is necessary to unscrew the screw and introduce from 1.5 to 3 ml of grease into the cavity of the gearbox, depending on the brand of the tool. For convenient dosage, you can use a traditional medical syringe.

During the operation, foreign particles and objects must not be allowed to enter the gearbox, as this can lead to intensive wear of the gear train, as well as its jamming.

Do-it-yourself how to disassemble, lubricate, replace or repair the trimmer gearbox

With frequent, intensive use of lawn mowers, the gearbox may start to warm up or make sounds uncharacteristic for its normal operation, for example, rattle. This indicates that the mechanism must be lubricated.

If this is not done on time, more serious problems will arise (for example, gears will quickly wear out and need to be replaced), up to jamming. With the transmission mechanism, other failures also occur.

Repair and lubrication of the gearbox can be done independently. for this you just need to get acquainted with the features of these works and stock up on some available tools.

Trimmer gear device

A trimmer reducer is a unit that transmits the rotational movement of the motor shaft to a knife or fishing line. It is located on the lower end of the bar. The transmission unit is also designed to reduce the trimmer engine speed.

The mechanism depends on the model of lawn mowers from several gears rotating at high speed. As a result, they heat up due to strong friction.

If there is insufficient lubricant, or there is none at all, the process leads to severe overheating and failure of parts, and, accordingly, the need for complex repairs.

To avoid this, lubricate the transmission unit in time. The disassembled gearbox is shown in the photo below.

Gearboxes of modern trimmers of different models from different manufacturers differ from each other in design and size of the seat. It happens:

  • round;
  • in the form of an asterisk;
  • square.

lawn mowers are equipped with gearboxes with different types of gears:

  • conical;
  • worm gears;
  • spyroid;
  • cylindrical;
  • planetary;
  • wave;
  • combined.

The drive shaft and gearbox are heavily loaded trimmer assemblies that are highly susceptible to wear.

Between them, the movement is transmitted due to the adhesion of the teeth of the gears located at different angles to each other.

Effectively the gear transmission works only if there are no mechanical damages. In this case, the mechanism should not overheat, otherwise it may jam.

The main malfunctions of the gearbox and their solutions

With the gearbox of an electric or gas trimmer, various failures occur. The most common of them are presented in the table below. There you can find the causes of their occurrence and methods of elimination.

Gear malfunctionPossible causes of failureRemedy
the transmission unit is very hotuse of unsuitable (poor-quality) grease or its absenceneed to replace or add lubricant
new gears and did not get usedrun-in for a short time without heavy loads with regular stops, so that the mechanism has time to cool down
jamming of the shaft during rotation, the appearance of play and knockingdestruction or significant wear of any of the bearingsreplace a failed bearing with a new one
the transmission mechanism flies from the bar of the lawn mowing or wobblesdamage to his bodyit is necessary to replace the part
in some cases, with minor damage by a clamp made of metal, they tighten the place with a fault
not fixed on the pipedock wearit is possible to make winding from an insulating tape in the place of fastening or to change a bar
the output shaft with the knife does not rotate or stops in case of increasing loadwear of teeth on gears or one of themreplacement of an interacting pair of worn parts is required

Bearings are destroyed due to the use of improper grease or due to its absence. They are also damaged by the harsh operating conditions of the lawn mowers and the ingress of foreign material particles (for example, broken metal teeth of mechanical gears) due to the fact that the integrity of the anthers is impaired.

To remove the bearing, you need to disassemble the gearbox and use a special puller. If it is not, then you can try to do it with a hammer with a tip.

In this case, work should be done carefully so as not to damage the seat. Using the preheating method to take pictures of the bearing is not recommended.

Most gearbox problems can be easily fixed by yourself. Replaceable parts are recommended to be purchased “native”, designed for the model used lawn mowers.

Grease trimmer gear

Gear lubrication should be carried out regularly in accordance with the recommendations set out in the operating instructions for the model used. This should also be done if:

  • new gears were installed;
  • atypical sounds emanate from the gear during the operation of the trimmer;
  • knives rotate heavily.

With constant use of the trimmer, its transmission mechanism is stressed by grass, dirt or sticking to the knives due to a change in torque. The lubricant must be selected high-quality to extend the life of the gearbox.

Used greases

Video: What kind of oil can be used for trimmer


When choosing a lubricant, the following factors must be considered:

  • the degree of adhesion of the composition to the metal node;
  • product brand;
  • lubricant consumption by gear.

Well-known manufacturers, for example, Stihl, Husqvarna and others, in addition to trimmers, also produce grease for them. Such products not only reduce wear, but also protect the metal of the gears from corrosion. Therefore, for lawn mowing from these brands, it is better to use their own lubricant products.

Different models use different lubricants. This is largely determined by the intensity of use of the lawn mowers and the heating of the transmission mechanism. It is believed that there is enough lubricant if the gearbox temperature during operation does not exceed 40 ° C.

By consistency, trimmer lubricants can be:

  • liquid;
  • semi-liquid;
  • solid;
  • plastic.

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 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 improving performance characteristics of components.

Examples 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 outlets.

Gear lubrication algorithm

To lubricate the gear mechanism, its preliminary disassembly is not necessary. A special hole has already been laid in the device for these purposes (it is shown in the photo below). In addition to gears during lubrication, attention must be paid to such elements of the mechanism:

  • bearing unit;
  • flywheel and starter coil dog.

Grease hole

Fill with oil or apply solid lubricant through grease fitting closed with a screw. In this case, perform actions in the following sequence:

  • the gear case is cleaned of dirt and adhering grass, the area around the plug is carefully carefully so that debris does not get inside the mechanism;
  • using the appropriate tool (often it comes with a trimmer), unscrew the cork;
  • the selected lubricant is introduced into the open technological hole from the tube, or using a syringe, as shown in the photograph below;
  • screw the cork into place.

Gear lubrication

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 the housing, the shaft, and only then use a new one. The disassembled mechanism is conveniently lubricated with solid formulations.

The entire gearbox lubrication process is demonstrated in the video:

It is required to lubricate the transmission unit at least once during the year, but it is recommended to do this every 20 hours of intensive use of the lawn mowers. If the first signs of malfunctions with the mechanism appear, then lubricant must be added as quickly as possible.

How to replace the trimmer gear: action algorithm

To replace the gearbox with a similar part from the same manufacturer, it must first be disassembled and removed from the rod. They act in accordance with the following algorithm:

  • loosen the coupling bolts located under the gear;
  • using pliers, remove two corkscrew rings;
  • applying a puller, pull bearings from the driven and drive shafts;
  • then assemble the mechanism, installing all the spare parts in reverse order.

A disassembled gear 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 are stuck and do not move 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 be necessary to lightly tap the hammer to fit the parts into place. After assembly, be sure to check that the driven shaft is rotated by hand.

When there is a need to replace the transmission unit with a non-original part, then you should consider them interchangeability. It should be borne in mind:

  • rod diameter (this parameter is often 25.4 or 26 mm);
  • drive shaft parameters. the shape of the docking place and diameter (its common value is 8 mm);
  • option to secure the protection.

If the considered parameters coincide, then it will be possible to install the part from other models.

Timely lubrication of the gearbox will ensure its continued operation without repairs. In addition, modern materials well protect the metal from corrosion, increase its wear resistance.

The preference when choosing should be given to the lubricant recommended by the manufacturer of the operated trimmer. If it is not possible to acquire such compositions, then the considered ones or other suitable analogous properties should be used.

When it is necessary to disassemble the mechanism during repairs, this should be done carefully so as not to damage individual parts.

What Lubricant To Use For Lawn Mowers

Lubricant selection for gearboxes and bearings at least some angle grinder, how to lubricate parts angle grinder, Makita. What grease is better for grinder reducers and how can it be changed.

Extensive distribution among lovers of tinkering was gained by angle grinders (angle grinder), popularly referred to as angle grinders. The cause of the mower’s electric motor failure. With the help of their home master can not only do grinding work, but also cut metal, plastic, stone. Angle grinders are made by different manufacturers, including Russian ones.

Angle grinder is a reliable tool that can work, with proper operation and timely change of grease and carbon brushes, over time.

Knowing the rules for choosing a lubricant for an angle grinder or making it yourself, you can do technical maintenance without contacting service.

Key lubricant characteristics for angle grinder

In angle grinders, the main unit subjected to heavy loads during operation is a gearbox consisting of helical gears.

The rotational moment created by the rotor of the angle grinder is transmitted from the rotor to the working tool through a small helical gear to a large helical gear. Correctly selected lubricant for the gearbox significantly reduces the friction force and heating temperature.

The grinder uses bearings, which also asks for repeated lubrication. Disassembly lawn mower motor Bosch This is especially true for the spindle bearing of a large helical gear.

Lubricants for an angle grinder should possess certain features and should be the desired mixture in terms of properties.

The gear lubricant for the angle grinder must have:

  • viscosity less than 800 Pa · s;
  • dropping temperature more than 120ºС;
  • tensile strength of more than 120 Pa.

Grease for an angle grinder does not have to have any mechanical impurities, be resistant to corrosion, hold tightly on lubricated parts, do not melt at high temperatures, prevent the formation of scoring at the contact points of parts and, of course, possess water-repellent qualities.

In any angle grinder, at least one office uses two types of plain bearings: bearings for an electric motor and thrust bearings for a gearbox.

Grease selection for motor bearings is different from grease selection for gearbox bearings. Motor malfunction in the lawn mower. It’s all about different work criteria.

Lubricants recommended by foreign tool manufacturers

Foreign tool manufacturers, including an angle grinder, recommend specially developed ointments as lubricants for grinders.

One of the common foreign lubricants is the lubricant labeled MoS2 NLGI 2 ISOL-XBCHB 2 DIN 51825-KPF 2 K-20.

  1. MoS2. shows filler material, in this case molybdenum;
  2. NLGI2. indicates 2nd grade viscosity;
  3. ISOL-XBCHB 2. belonging to ISO standards;
  4. DIN 51825-KPF 2 K-20. grease made according to German standards DIN;
  5. The numbers 51825 indicate that the grease is of type K.

Lubricants produced with such features are quite expensive. On the Russian market are imported from other countries, the least expensive lubricants.

Each tool manufacturer, be it Bosch, Makita, Hitachi, DeWalt, Metabo, RedVerg, Interskol, E256, LEPSE, advises its lubricants. This is a manufacturer policy. They insist that the lubricants specified in the instructions be used when performing maintenance. At the same time, non-compliance with these tips does not allow for warranty repairs.

Gearbox grease Makita angle grinder is available in tubes. Its highest price is commensurate with the highest quality and long life.

Lubricants of domestic manufacturers for bearings and gears of grinders

With the growth of prices for foreign lubricants, lubricants of Russian manufacturers became especially needed.

Russian manufacturers of lubricants have learned how to produce high-quality lubricants suitable for at least some tools.

Lubricants have been developed for reducers of grinders, rotary hammers, drills.

Nanotech Metal Plac Electra products are especially popular. Disassembly lawn mower motor video. The range of lubricants produced by this company allows you to choose the right lubricant for each unit

REDUCER Lawn mowers. HOW TO LUBRICATE AND HOW IT IS EASY TO DETERMINE WHAT IT NEEDS TO LUBRICATE

WHAT TO DO WITH EDITOR lawn mowers that he served for long and long years.

Three bearings are installed in the design of the angle grinder. Two bearings are installed on the rotor of the tool, one bearing is installed on the shaft of the driven helical gear of the larger diameter.

The angle grinder uses bearings already filled with grease. Winding circuit of a lawnmower electric motor. But from improper use, overheating of the tool grease leaks.

How to choose the right grease for bearings angle grinder?

Bearing grease must meet the following requirements:

  • increase glide;
  • reduce friction between the component parts;
  • distribute heat moderately and play the role of cooling water;
  • prevent corrosion;
  • protect against ingress of dirt and dust;
  • work in the required temperature range up to 150C;

The operating conditions of the electric motor bearings differ from the operating criteria of the gearbox bearing, not only because of temperature requirements, but also because of operating modes, load conditions, frequency and speed of rotation.

Grease for bearings of the electric motor must possess protective qualities that prevent the ingress of dirt, dust and water on the bearing parts.

The Russian market has a wide range of foreign lubricants designed for bearings operating under various criteria. But their price makes it necessary to find cheaper, not inferior in quality, Russian lubricants.

Of the Russian lubricants, we recommend that you pay attention to the lubricants Tsiatim-221, VNIINP-246 (GOST 18852-73), VNIINP-235.

Well proven lithium grease.

Of pigment grease VNIIMP-246 blue grease and VNIINP-235 dark purple ointment were widely used for electric motor bearings. Due to the high price, the first grease is less common than the second.

In today’s Russian market, domestic manufacturers lubricants presented in a wide product line.

Gear Lubrication Angle Grinder

Grease for the gearbox angle grinder differs from the grease for bearings main feature. increased adhesion. It should firmly adhere to the teeth of the gearbox with a large rotation.

In general, the process of lubricating the gearbox in angle grinders occurs due to the fine spraying of the lubricant and its suspensions. Replacing an electric motor in a lawn mower. The gearbox works as if in oil mist. The device of the electric motor in lawn mowers. Therefore, the lubrication requirements for gearboxes are slightly different.

In addition to increased adhesion, grease for gearboxes must have high heat resistance and not melt at elevated temperatures.

DIY grease for gear reducer

Given domestic lubricants, although affordable, they are not always at hand.

Is it possible to make grease for the gear reducer of the angle grinder with your own hands

And there is an affirmative answer to this question.

Since the main technical specifications lubricants for gearboxes the angle grinder is presented above, then they can be taken as the basis for making the grease of the desired characteristics with your own hands.

The basis of homemade grease for gearboxes should be a grease with high adhesion. It should hold tight to contacting parts.

Taking the lubricant for CV joints as a basis, it is necessary to add a liquid lubricant (MS-20) to give the mass the desired consistency. MS-20 oil must be served dropwise, thoroughly mixing the mass with a home-made mixer.

Good results are obtained from a mixture of a mixture of lubricant Tsiatim-221 and TAD-17, where the basis is Tsiatim.

Correct lubricant filling process in angle grinders

Stuffing grease in the nodes of the angle grinder has its own rules. You need to know not only the order of its application, but also how much and where to put it.

When to change grease in an angle grinder

The lubrication of the angle grinder changes according to the maintenance plan of the tool when replacing failed gear parts or rotor bearings.

Old grease has a dirty dark color. This is due to the ingress of foreign particles of metal or dust.

How to remove old grease in an angle grinder

Old grease is always removed completely regardless of its color. The parts should not have traces of old grease, but in the cavities of the particle housing of the destroyed parts.

To remove old grease, you can use various flushing fluids used by motorists to wash the motor and its parts. Electric motor device for lawn mowers. At home, it is recommended to use kerosene or a solution of kerosene and gasoline.

All parts and their cavities must be thoroughly washed and dried.

Lubrication procedure for gearbox angle grinder

New grease Before application, mix thoroughly and apply a thin layer. Tigo lawnmower electric motor device. The bearings are lubricated by packing. If the grease is in a plastic tube, then the neck of the tube is attached to the side bearing cage and squeezed out before it flows out of the back side.

How much grease should be used when replacing the angle grinder in the gearbox

If the amount of grease in the bearings is controlled by leaking it from the back, then a certain amount of grease is packed into the gear of the angle grinder. Excess grease will leak during operation. And its small number will not ensure high-quality operation of the gearbox.

Leave as much lubricant in the gearbox as needed to cover the gear teeth.

For reference, apply so much grease so that it occupies a little less than half the volume of the cavity of the gearbox.

Checking the correct application of lubricant to the gearbox angle grinder

The control of the volume of grease stuffed into the gearbox is carried out by trial inclusion of the assembled angle grinder for a short time at idle.

If the gearbox began to heat up, traces of leakage of grease appear from the seals and gaskets, then the conclusion is clear. You shifted the grease. Open gear case and remove excess grease. Mower motor malfunction. All excess grease will be placed on the gear housing covers. The insufficient amount of lubricant in the gearbox is determined by the increased noise of the gearbox.

During prolonged use, the angle grinder lubricant in the gearbox is distributed on the walls of the housing and loses its properties from external influences.

Having opened the gearbox cover, carefully inspect the condition of the lubricant, gear tooth profile. If you can, check the contact patch of the gears.

The presence of particles of dry or dried grease in the area of ​​the gearbox or on the housing indicates that the time for changing the grease has come.

What Grease To Lubricate A Trimmer Reducer

It is believed that there is no universal lubricant for the trimmer gear, but this is not entirely true. Essentially, a suitable lubricant is the one in which the following components are:

From time to time, in the midst of intense work on mowing the grass stand, your trimmer begins to make nasty, grinding sounds. It complains about the lack of lubrication gearbox. a more actively loaded device node. And soon these “warnings” may be followed by jamming of the drive.

What grease should be used for the trimmer gearbox?

In the process, the mechanical part of the trimmer is loaded with contact forces on the teeth, resistance reactions from adhering weed (from time to time with grease), dynamic, shock loads due to constantly changing torque. Grease for the trimmer gearbox, these features must be fully taken into account, therefore the selection of the brand must be strictly personal.

The following reasons are taken into account:

  1. Brand of the manufacturer. Any brand is not unreasonably oriented on lubricants of its own production (you can talk about cheap Chinese products later). This applies to manufacturers such as Husqvarna, Stihl, Huter, Makita, etc. The exception is Russian-made trimmers: for example, Caliber in the user’s annotation generally does not show the lubricant brand.
  2. The viscosity of the lubricant. As you can see, all lubricating compositions are divided into three groups. highly viscous (colloidal systems containing different additives), plastic compounds of universal application and solid lubricants that soften during operation.
  3. Excellent adhesion to the surface of the gearbox parts, as a result of which the lubricant is not squeezed out into the gaps or out of the assembly.
  4. Intensity of lubrication with a gearbox. Here you have to rely on your experience and the advice of professionals, since some trimmer manufacturers, relying on the availability of their own service centers, generally do not give clear advice on the period of operation of the gearbox between 2 lubrications.

The lubricant consumption also depends on the temperature at which it retains its lubricity. When the gearbox is heated to 40 ° C, it is considered that its operating conditions are satisfactory, and there are enough lubricants.

It is believed that there is no universal lubricant for the trimmer gear, but this is not entirely true. In fact, a suitable lubricant will be one in which the following components are present:

  • Antiwear additives, which contain no toxic lead;
  • Solid lubricants with the presence of graphite or molybdenum disulfide (the latter is better, because with all this, the lubricating ability is one hundred percent preserved for a huge range of shaft revolutions);
  • Only mineral (inorganic!) Oils, with the highest degree of purification.

These requirements are fully met by Gear Grease OREGON or Champion EP-0 lithium greases, Russian compositions Oleo-Mas, Litol.24, or Azmol 158, also those recommended by the manufacturer of a certain trimmer model.

how grease trimmer gear?

In the upper part of the housing, where the gear block is installed, there is a technological hole, which, when the trimmer is operated, is plugged with a screw. This screw is loosened, and 1.5. 2 ml of grease is introduced into the hole using the nozzle on the tube. If the grease was purchased in a different packaging, then for this operation a mundane, single syringe honey is suitable.

Then the screw is installed in its original place. This function, regardless of the user’s advice, should be done every 10. 15 hours of operation trimmer in operating mode.

Other reasons for updating or replacing the gearbox lubricant are the independent performance of small routine maintenance (for example, cleaning and washing the gears of the gearbox before the summer season), repair of the unit, preservation of the trimmer for the winter period, etc.

If the gear unit is disassembled, it is recommended to completely remove the remains of the previous grease from the surface of the parts, even if it does not have any signs of oxidation and contamination. And only then apply new grease. After applying the lubricant, it is recommended to rotate the shaft manually a couple of times, and make sure that the lubricant is moderately distributed over all parts of the gearbox.

When lubricating, increased attention is paid to the following elements:

  1. Flywheel: on its surface, usually, the remains of the grass adhere actively, and the thickening herbal juice creates additional resistance.
  2. The starter coil dog, which is constantly in contact with the grooves on the flywheel when the drive is turned on. With all this, not only mechanical wear occurs, but also mechanochemical corrosion of the flywheel-dog joint, since the materials for this pair are different (the flywheel is duralumin and the dog is iron).
  3. Bearings, if their seals are worn, and through their remnants of grease are squeezed out. In this case, the unit begins to vibrate actively when loaded. This happens with trimmers made in China, so in the future it is worth thinking about replacing the bearing assembly with a higher-quality one, for example, from the Swedish company SKF.

How to lubricate the trimmer gearbox? Trimmer lubrication points

Proper maintenance is the key to continued and reliable tool operation. Primitive care operations include timely lubrication of the gearbox and cleaning of the trimmer filter. And how to lubricate the trimmer gear, every user should know. Cleaning is carried out in several stages:

  • After removing the casing, the element is removed.
  • Then it is washed with gasoline and dried (naturally).
  • The place under the filter is cleared of the remains of oil and dust.
  • Check the rod for rotation during operation.

Is it possible to lubricate the trimmer gear with solid oil if there are no other means? No, for a long service life, machinery manufacturers recommend using specialized greases. Some manufacturers are developing care products that are tailored directly to the branded tool. To lubricate the working steam, you only need to unscrew the plug and pour liquid into the container.

Gearbox lubrication process

A gearbox is a mechanical device that is designed to transmit torque from the engine to cutting equipment. Located at the bottom of the trimmer.

Immediately before maintenance work, remove the electric cap (or plug from the plug). Do not overturn the trimmer to prevent fuel leakage. To replace grease, disassemble the device.

The disassembly process consists of the following steps:

  1. The side screw is unscrewed.
  2. If there is no trace of grease, then it should be added (3-4 grams).
  3. Next, the gear is manually scrolled. This is done to evenly distribute the material across the gears.

The operation is performed several times. The assembly should be tightly greased. At the end of the operation, the screw is put in place and tightened tightly.

To lubricate the trimmer gearbox, it is necessary to clean the plug and the area around it from dirt, and then unscrew it. lawn mowing fits on the left side. By rotating the gearing, lubricant is simultaneously added to the gear housing until it is full.

How to choose the right lubricant

During operation, the nodes of the mechanism are loaded with contact forces on the teeth, resistance reactions in the event of debris, as well as dynamic and shock loads. Depending on the characteristics of the load, you should choose how to lubricate the trimmer gear.

In the selection should take into account such factors:

  • brand of the manufacturer;
  • lubricant viscosity (selection of this parameter depends on the torque of the shaft);
  • adhesion to the surface of the parts of the site;
  • the intensity of lubricant consumption (the ambient temperature, type and amount of work should be taken into account).

In the absence of the necessary lubricant, you can use the universal. The latter should contain some components:

  • antiwear additives (no toxic lead);
  • highly refined mineral oils (inorganic);
  • solid lubricants with graphite or molybdenum disulfide.

Varieties of lubricants

To care for the nodes of the mechanism, greases of different consistencies are used:

  • Semi-liquid. Such formulations contain a variety of additives and additives.
  • Plastic. They are the most versatile option. Most often used for gears and helical gears.
  • Solid. Plate suspensions in their original state.

Special gearing composition refers to a semi-fluid system.

Popular is the “Stihl” trimmer grease. Thanks to the special composition and components, wear is significantly reduced and corrosion resistance is increased. The main properties of the grease of this brand are:

  • oxidation resistance;
  • high penetration;
  • resistance to high temperatures;
  • high adhesion.

“Stihl” grease is suitable for brush cutters and trimmers, as well as for all transmissions with a closed housing.

Faults and solutions

  1. Strong (or fast) heating. The main reason is the lack of lubrication. If such a malfunction is detected, add lubricant and run the tool in a gentle mode.
  2. Increased vibration, staggering gear.

The reason is mechanical damage. It is eliminated by tightening the housing or replacing it. The presence of knocking, play or jamming when rotating the shaft. The causes of the malfunction are bearing destruction, anther damage.

To prevent such defects from occurring, the trimmer gearbox should be lubricated. How and at what frequency to lubricate is indicated in the instructions from the manufacturer. Jamming of the trimmer knife at high loads. The reason is tooth wear.

This problem cannot be fixed. A complete replacement of the mechanism is required.

Trimmer lubrication points

For smooth operation and durability of the mechanism, a thorough inspection and care should be carried out. An important point is the lubrication of moving parts. In most cases, these are:

  • place from the transition from engines to a straight shaft;
  • straight shaft joint with flexible;
  • transition of a shaft with a landing head;
  • gearbox.

Popular among users is the multi-purpose waterproof grease “Litol-24”. The range of operating temperatures is from 40 to 120 degrees. This grease is used in friction units and is effective at elevated temperatures.

Trim Grease Properties

In the production of lubricants, special substances are used that must meet environmental norms and standards. After development, they decompose without causing harm to the environment.

The consistency of the material initially has a high level of viscosity, and in the process, this parameter decreases. This factor provides complete penetration and reliable protection of working pairs under heating conditions.

Long-term use and smooth operation are ensured by timely and proper care. A variety of materials are used to perform care operations.

Grease is added to the petrol trimmer gearbox every 8-10 working hours.

User Lubricant Reviews

Experts advise using only original materials, the characteristics of which meet the manufacturer’s requirements. If there are none, you should clarify how to lubricate the trimmer gear.

Experienced users do not recommend the use of solidol, because this material is not suitable for the temperature and speed characteristics of the unit, as well as for consistency.

Also, the given material does not have antiwear properties.

The range of operating temperatures of a solid oil is from minus 40 to 65 degrees, but even with such parameters, the density of the material increases during heating and the lubricant becomes coarse. In case of urgent need to process the tool, you can use “Litol-24”.

Gas trimmer maintenance

Most lawn mowers and trimmers have a flexible shaft in their design. Its condition must be checked at least 1 time for 50 working hours. To perform this operation, you need to remove the tip of the rod, pull out the shaft and inspect it, then grease.

In order to care for the shaft, inexpensive materials are suitable, it is more difficult to choose them for the trimmer gearbox. How to lubricate this mechanism. depends on the manufacturer of the tool. It is best to use materials that contain molybdenum disulfide. The latter provides smoothing and filling of cracks on the working surface, therefore it is especially appreciated among users.

Important: the use of a large amount of grease with a high density leads to overheating of the mechanism, increased friction of working pairs and fuel consumption. Therefore, the process of selecting materials and prevention should be treated responsibly.
