What Oil To Fill In The Trimmer Gear

Lubricant for trimmer gear. How and how to lubricate?

Sometimes, in the midst of an intense mowing operation, your trimmer will start making an unpleasant grinding noise. This complains about the lack of lubrication of the gearbox. The most heavily loaded unit of the device. And soon on These “Warning” may follow and jamming of the drive.

Range of lubricants for garden equipment

According to the instructions, use a special transmission fluid grease to lubricate bevel gears. As a rule, manufacturers of garden equipment 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 brand of auto chemistry, the lubricant for garden equipment is usually made multifunctional. It is designed not only to lubricate the gearboxes of gasoline trimmers, but also for the treatment of hoses, gears and gearboxes of any garden equipment and mechanical devices operating under high loads.

Even if the specialized gear lubricant is almost completely depleted during operation, the additives still create an effective lubricating protective film on the gear surface.

It should be noted that many owners of lawn mowers in the vastness of the former CIS use ordinary Litol-24 or lithium-based grease for CV joints to lubricate the gearbox. It is convenient to refuel the reducer using a 5-cc medical syringe. Many motorists, instead of the side screw, pick up the thread and screw in the grease gun from the used crosspiece of cars. This revision allows the addition of Lithol without disassembling the assembly using a grease gun.

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

How to Lubricate the Trimmer Gearbox?

In the upper part of the body, where the gear block is installed, there is a technological hole, which is plugged with a screw during trimmer operation. This screw is unscrewed, and 1.5. 2 ml of lubricant is injected into the hole using the spout on the tube. If the lubricant was purchased in a different package, then an ordinary disposable medical syringe is also suitable for this operation.

After that, the screw is reinstalled. This procedure, regardless of the user’s recommendations, should be performed every 10. 15 hours of operation of the trimmer in working mode. Other reasons for updating or replacing the gearbox lubricant are the independent performance of minor routine maintenance (for example, cleaning and flushing the gears of the gearbox before the start of the summer season), repairing the unit, preserving the trimmer for the winter, etc.

If the gear unit is disassembled, it is recommended to completely remove the remnants of the old grease from the surface of the parts, even if it does not have any traces of oxidation and contamination. And only then applies a new lubricant. After applying the lubricant, it is recommended to turn the shaft several times by hand and make sure that the lubricant is evenly distributed over all parts of the gearbox.

When lubricating, pay particular attention to the following elements:

  • Flywheel: grass residues tend to stick to its surface intensively, and thickening herbal juice creates additional resistance.
  • The dog of the starter coil, which, in the process of turning on the drive, constantly contacts the grooves on the flywheel. In this case, not only mechanical wear occurs, but also mechanochemical corrosion of the “flywheel-dog” connection, since the materials in this pair are different (the flywheel is aluminum, and the dog is steel).
  • Bearings, if their seals are worn out, and through them the remaining grease is squeezed out. In this case, the unit begins to vibrate intensively when loaded. This happens with Chinese-made trimmers, so in the long run it is worth thinking about replacing the bearings of the assembly with a better one, for example, from the Swedish company SKF.

How to properly lubricate the trimmer gear?

At the top of the case, where the gear block is located, there is a technological hole, which is covered with a screw during trimmer operation. This screw is unscrewed, and 1.5-2 milliliters of grease is introduced into the hole from the nozzle of the tube. If the purchased composition has a different packaging, then an ordinary syringe will work to inject the mixture into the hole. After the screw is placed in its rightful place.

This operation, regardless of the user’s recommendations, should be repeated after every 10-15 hours of trimmer operation. In the second cases, the replacement and renewal of the gearbox lubricant is carried out when the device is preserved before winter, the unit is repaired, the gears are flushed and cleaned at the beginning of summer, etc.

When disassembled, before applying new grease, it is worth initially completely removing the remnants of the old mixture, even if they are NOT contaminated or oxidized.

After applying new grease, the shaft should be turned by hand a couple of times to make sure that the composition is equally distributed over all surfaces of the gearbox.

It is important to pay particular attention to the following trimmer components during the lubrication process:

  • Bearings with a worn seal, through which grease residues could escape during operation of the unit. If there is a lack of lubrication, in this case, the device begins to vibrate noticeably. This often happens with Chinese models, when choosing which you should think in advance about replacing the bearings of the unit with the highest quality analogue, for example, the Swedish SKF.
  • The starter coil dog, as it often touches the grooves on the flywheel when the drive is turned on. In addition to mechanical wear, in this case, mechanochemical corrosion also occurs between the joints of the pawl and the flywheel, since these components are made of different materials. the dog is made of steel, the flywheel is made of aluminum.
  • A flywheel, on the surface of which the remains of grass usually accumulate, and as you know, thickened herbal juice exerts excessive resistance.

Lubrication for the trimmer gear is selected based on many of the parameters described above. Carefully consider all of them, and then the device will serve you regularly for a long time, always pleases with a mowed lawn and a well-tidied area.

  • Time and procedure for preventive maintenance of the gearbox.

    I recommend in order to carry out the prevention of a new gasoline trimmer immediately after purchase, with the addition of lubricant to the gearbox. With all the high cost of garden equipment, some manufacturers save money and put in lubricant only at a minimum, for the run-in time.

    What kind of lubricant should be used for the trimmer gear?

    During operation, the mechanical part of the trimmer is loaded by contact forces on the teeth, resistance reactions from adhered grass (sometimes with dirt), dynamic, shock loads due to constantly changing torque. Lubricant for the trimmer gear must fully take into account these features, so the selection of the brand must be strictly individual.

    The following factors are taken into account:

    • Manufacturer’s brand. Each brand reasonably focuses on self-made lubricants (you can talk about cheap Chinese products later). This applies to manufacturers such as Husqvarna, Stihl, Huter, Makita, etc. The only exceptions are domestic trimmers: for example, the Caliber in the user manual does NOT indicate the brand of lubricant at all.
    • The viscosity of the lubricant. As you know, all lubricating compositions are divided into three groups. high-viscosity (colloidal systems containing various additives), plastic compounds for universal use and solid lubricants that soften during operation.
    • Good adhesion to the surface of gearbox parts, as a result of which the grease is NOT squeezed out into the gaps or out of the unit.
    • The rate of grease consumption by the gearbox. Here you have to rely on your own experience and the recommendations of specialists, since some trimmer manufacturers, relying on their own service centers, do not give clear recommendations at all for the period of the gearbox operation between two lubrications.

    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 is sufficient lubrication.

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

    • Lead-free antiwear additives;
    • Solid lubricants with the presence of graphite or molybdenum disulphide (the latter is preferable, since the lubricity is fully retained for a wide range of shaft speeds)
    • Only mineral (inorganic!) Oils, highly refined.

    These requirements are fully met by Gear Grease OREGON or Champion EP-0 lithium greases, domestic compositions Oleo-Mas, Litol.24, or Azmol 158, as well as what is recommended by the manufacturer of a particular trimmer model.

    Lubricant for trimmer gear: features of the selection and application of the composition

    Sometimes, with intensive mowing of the grass, the trimmer starts grinding and making unpleasant sounds, which indicate the lack of lubrication of the gearbox. This unit is considered the most loaded, and then wears out faster. If it is NOT lubricated in a timely manner, then soon the drive may jam!

    Why does the oil change

    The rear axle gearbox is a mechanism that is subjected to a number of different stresses. Through THESE loads, Destructive actions arise. To avoid accelerated wear of the gearbox parts, a special lubricant is required. This grease is an oil that, during the operation of the gears of the mechanism, envelops them, eliminating accelerated wear, overheating, and also cleans the teeth from chips and metal dust.

    It is necessary to change the oil in the rear axle gearbox for the simple reason that over time it loses its primary properties. When the gears rub against each other, heat energy is released, the value of which is reduced with the help of a lubricating fluid. In addition, the friction of the gears causes wear on the teeth, which generates chips and metal dust. If you DO NOT change the lubricant in the gearbox for a long time, the amount of metal chips and dust will only increase, which will lead to accelerated wear of rubbing parts.

    Oil in the gearbox of the rear axle VAZ 2107: selection, replacement

    Domestic car VAZ 2107 refers to rear-wheel drive vehicles. The rear wheels are driven by the rear axle and cardan drive. An important role in this is played by the rear axle, which is a gearbox for converting torque from one value to another. This is the mechanism in which the gears rotate. Oil is used to reduce the friction of THESE gears. What oil is recommended to be poured into the gearbox of the rear axle of the VAZ 2107, and will be discussed in this material.

    Features of the choice of grease

    It is recommended to fill in semi-synthetic gear oil into the gearbox of the rear axle of a VAZ 2107 car. It should have a viscosity rating of 75W-90. This is a universal lubricant option, which is usually poured into the gearbox.

    A special gear oil in the gearbox improves the quality of the parts and also reduces their wear. How much oil needs to be poured into the gearbox, not every owner of the “seven” knows. The lubricant volume for the gear unit is 1.35 liters. It is poured through a special filler hole (on the side), using a technical syringe. Previously, the old lubricating fluid should be drained, for which there is a special drain plug from the bottom.

    When to change gear lubricant

    The oil change in the rear axle of a VAZ 2107 car should be performed regularly, but there is no specific threshold. It all depends on many different factors, but the manufacturer of the domestic car recommends performing this procedure every 60 thousand km.

    Some of the main factors that affect the timing of an oil change are:

    • Driving nature. Frequent and abrupt starts are NOT at all beneficial to the parts and mechanisms of the car, including the rear axle.
    • Car operating conditions. If the car is operated in a rural area, where there are roads with poor coverage, dust, dirt, then it should be replaced more often.
    • The quality of the lubricant. It is recommended to fill in a special high-quality oil into the rear axle of the VAZ 2107. If you pour low quality grease into the gearbox, then you will need to replace them much more often.
    • Vehicle operation with a trailer. The wear of the device parts is accelerated if the car is operated with a trailer in which the cargo is transported.

    Oil change step by step

    The procedure for changing the oil in the gearbox with warming up the old gum, for this you need to drive a car for 10-15 minutes. After that, you need to go to the inspection pit, take the necessary tools and materials, and go downstairs. The replacement procedure involves the following manipulations:

    A breather is located at the top of the bridge. After filling the oil, check its movement characteristics. It should move easily and without jamming. If the breather does not function, then when the grease heats up in the gearbox, it will begin to flow out through the oil seals.

    At this point, the process of changing the oil in the rear axle can be considered complete. If during the trip you hear a hum or howl from the rear of the car, it is recommended to carry out repairs before changing the oil, but this is a completely different story.

    In the gearbox

    The gearbox is the most important part, because it is he who is responsible for converting and transmitting torque from the gearbox. Careful care and high-quality oil used for the device significantly extends its life.

    To replace the oil composition in the gearbox, it is necessary to perform a number of manipulations.

    • The tiller must be placed on a hill. best of all on a pit.
    • Then the hole for the disposal of used oil is unscrewed. The locking plug is usually located on the gearbox itself.
    • After that, a prepared container is substituted for draining the spoiled lubricant.
    • After completely draining, the hole must be tightly closed.
    • When these manipulations are carried out, clean oil must be poured into the gearbox.
    • Then you need to screw the hole plug.

    The initial oil change is made after the break-in time has passed. For example, in the Energoprom MB-800 model, the break-in time is 10-15 hours, in the Plowman ТСР-820 unit. 8 hours. But the line of tillers “Oka” is designed taking into account running in 30 hours. Subsequently, it is enough to drain and fill in new oil every 100-200 hours of full operation.

    In the engine

    The primary oil change in the internal combustion engine occurs after 28-32 hours of operation. The next replacement can be done NOT more than 2 times a year. in summer and winter, even if the unit has been idle for some time. To start the replacement process itself, it is necessary to prepare special attributes. a funnel and a container for draining the spent liquid.

    At the bottom of the engine there is a hole with a cap through which old oil can be drained. In the same place, a container for draining is substituted, the locking cap is unscrewed, and the waste liquid is drained. It is necessary to wait some time for the residues to completely drain out of the engine system. Then the plug is screwed into place, and fresh oil can be poured.

    Its quantity must be identical to the drain. If it is not possible to make a measurement, it is better to look at the technical data sheet of the unit, where the required number is indicated in grams. After new oil has been added to the engine, the level must be checked. To do this, just use a special probe.

    This instruction is a general guideline for both two-stroke and four-stroke models. specific information on how to change the oil fluid in the tiller is better viewed in the instructions for a particular unit.

    Tiller oil: which is better to fill and how to change?

    Buying a tiller is a pretty serious step that should be prepared in advance. For the long-term operation of the unit, it is necessary to carry out timely preventive work, if necessary, replace parts and, of course, change the oil.

    How to change?

    Anyone can change the lubricant in the tiller, but if there are any doubts, it is better to contact a highly qualified specialist. The procedure for updating with oil liquid in any model of chillers is NOT different from each other, whether it is an Enifield Titan MK1000 instance or any other motor from the Nikkey line.

    Thanks to the above nuance, the warm spent mixture easily flows into the container placed below. After the used oil is completely gone, you can start the replacement process.

    First you need to Unscrew the breather plug, drain the remaining used oil and, if necessary, change the additional oil and air filter. Then you need to fill in fresh liquid and return the plug to its place. Pour new oil carefully so that it does not get on other parts of the system, otherwise an unpleasant odor will arise.

    Which is better to choose?

    As mentioned earlier, there are several types of tiller oils. It is necessary to use the liquid recommended by the manufacturer of the unit. for this, it is enough to carefully study the labeling of the device and read the instructions.

    In addition, each separate type of oil is divided into several types according to its chemical composition. In most cases, manufacturers try to manufacture units with the ability to use the most common types of oils. synthetic, mineral, and semi-synthetic, for example, Mannol Molibden Benzin 10W40 or SAE 10W-30.

    It should be noted that this lubricant contains a friction modifier, which creates a strong film on the inner surface of the parts. This significantly reduces the wear rate of the tiller.

    Another marking that should not be forgotten is the designation of the properties of oil exploitation. It also comes in several varieties. For example, category C is used for 4-stroke diesel engines and category S is used for gasoline engines.

    From THIS data, a certain total can be derived. Given the engine variety, a high level of demand is directed to multigrade oils labeled 5W30 and 5W40. Of anti-corrosion oils, 10W30, 10W40 are popular.

    How to check the level?

    Checking the oil level is carried out using standard technology, to which everyone is accustomed. For this, a special probe is present in the tiller’s device, which goes deep into the unit. After removing it from the hole, at the tips of the dipstick you can see a limit strip, the level of which is equal to the level of the oil. If there is not enough liquid, then it must be topped up. On the other hand, this nuance forces you to check the entire system, since a low level of lubricant indicates that it is leaking somewhere.

    In addition to the standard dipstick, some models of the tillers have special sensors that automatically indicate the amount of lubricant present. Even in the process of replacing the oil liquid, it can be used to determine how much the size of the lubricant composition has grown or its lack.

    Appointment

    When buying a new tiller, the kit must contain accompanying documents, in which there are special sections with recommendations for proper care and operation. The names of oils ideally suited to the unit are also indicated there.

    First of all, you should understand the basic functions of oil fluids. Liquids do the following:

    • System cooling;
    • Getting the smearing effect;
    • Cleaning the inside of the engine;
    • Seal.

    During the operation of the tiller in an air-cooled engine, the oil liquid begins to burn, respectively, the burnt particles remain on the cylinder. That is why a smoky exhaust is formed. In addition, resinous deposits are the strongest contaminants for the rest of the tiller, due to which it becomes more difficult to lubricate the parts.

    For the correct choice of oil fluid, remember that each individual composition is designed for a specific season and climatic temperature.

    • The summer type of oil liquid is used exclusively in the warm season. Has a high level of viscosity. No letter designation.
    • Winter oils are used during cold weather. They have a low level of viscosity. The letter designation is W, which means “winter” in translation from English. This variety includes oils with the SAE index 0W, 5W, 10W, 15W, 20W, 25W.
    • A variety of multigrade oils is more popular in the modern world. Their versatility allows you to fill the engine with fluid at any time of the year. It is these lubricants that have a special index in the general classification: 5W-30, 10W-40.

    In addition to seasonality, oils are divided by composition. They are:

    • Mineral;
    • Synthetic;
    • Semi-synthetic.

    In addition, all oils differ in the performance requirements of 2-stroke and 4-stroke engines.

    The price of the issue, of course, is high, but the reaction of the unit lies in its long service life.

    Can I use car oil?

    It is strictly forbidden to use engine oil in chillers. Unlike a car engine, a Tiller has certain principles of lubrication and an appropriate temperature regime for operation. In addition, tiller engines have certain features. These include the material of construction from which it is made, as well as the degree of forcing. In many cases, these nuances are incompatible with the characteristics of automotive oils.

    Worm gear oil

    Today, worm gears are very widespread, as they are part of various devices. The main purpose is the direct transfer of force from the electric motor to the direct actuator. The principle of operation, as a rule, is based on the interaction of two or more elements, which are constantly in mesh. Excessive operating times under load and a low oil level in the gearbox cause abrasion of the main components. That is why it is important to choose the right oil for worm gearboxes and replace it in a timely manner.

    Selection of the right oil

    It is important to choose the right lubricant for your machine. This is due to the fact that there are worm gearboxes with a bronze worm, which require lubrication with certain performance properties. Among the features of the choice, I attributed the following points:

    • It is necessary to use only a special substance, it is not recommended to use the version for the motor, since it has second properties.
    • The classification is carried out in terms of viscosity, temperature conditions of use and many other parameters. The most important is the temperature regime, since it affects the properties. At a low value, the density value may increase, a high one leads to strong liquefaction and a decrease in characteristics.
    • Many manufacturers of worm gears indicate which version is most suitable. In some cases, this is an advertising move, you can choose another Similar substance that will have the corresponding properties.
    • Attention is also paid to the popularity of the lubricant manufacturer. The product of famous brands is characterized by the fact that the declared characteristics correspond to the real ones.

    Besides, one of the main selection criteria is the price. There is just a huge assortment of the product in question on sale, so there are no problems with selecting the most suitable version.

    Gearbox oil change intervals

    A fairly common question is how often and why to change the oil in the gearbox. Most experts recommend carrying out the replacement in accordance with the spent resource. For automatic transmissions, this figure is 30 thousand kilometers, in the case of mechanics, the figure is 50 thousand kilometers.

    The replacement is carried out for the following reasons:

    • Over time, due to overheating and second exposure, the basic properties of the oil deteriorate. An example is a decrease in lubricity and many other points. That is why the device will NOT last for a long time.
    • Natural wear and tear of metal products becomes a prerequisite for which there is a large amount of metal shavings in the composition. It becomes a prerequisite for strong heating due to the resulting friction.
    • Deterioration of the basic lubrication properties of the worm gear becomes a prerequisite for overheating and increased wear of the main elements.
    • Over time, the amount of lubricant decreases naturally. At the same time, manufacturers DO NOT recommend mixing mining with a new one, as this will only reduce the main operational characteristics.

    In addition, attention is paid to what kind of oil is needed to provide reliable lubrication of the main elements.

    Replacement recommendations

    Changing the lubricant does NOT create significant problems in most cases. This is due to the fact that the machine and other equipment have a special hole for filling in oil. Grease for worm gears is sold in certain containers, filling is carried out using a watering can. Other recommendations include the following:

    • It is not recommended to mix the old substance with the new one. This is because contaminants remain in the worm gear when diluted. This procedure does not solve the problem associated with overheating and wear of the considered structure.
    • In each case, a certain amount of substance is required. In the usual worm-gear version, approximately 1/3 of the volume is filled, Lubrication is carried out by spreading during rotation.
    • Drainage of working out in some cases can create difficulties. There is usually a corresponding drain hole at the bottom.

    Certain mechanisms must be serviced exclusively by a specialist. An example is automatic transmissions, which are also based on the use of a modified worm-type gearbox.
