Can the grass trimmer be lubricated with solidol. Bearing grease for angle grinder
Can the gearbox of a brushcutter be lubricated with solidol
The following rules are compulsory when taking care of your lawn mower:
On no account should the knife blocks be washed with running water, as this will inevitably lead to corrosion.
The use of edible vegetable oil, let alone machine oil, will cause serious problems. The blades will start to slip, and the device will break down quickly.
Do not randomly pour large quantities of liquid. It should only go into the contact areas of the knives.
If you do not adhere to this rule, even a brand-name device will not work in the best way, which will affect the quality of the haircut.
Please pay attention to the non-disassembled models. They have special holes for pouring oil
Before cleaning, please read the instructions carefully.

We not only have lubrication products for your power tool, but also hair styling products and other products that will make your appearance perfect.
First you need to disassemble the bar. With a regular chain saw, this is done by simply disconnecting it from the upper and lower gears.
If the grasshopper mower has a collapsible rod, consisting of two parts, it is even easier. All that is required is to remove the coupling sleeve in the center and separate the halves.

If the grasshopper has already been in operation, you may notice some wear on the shaft, or shafts in the case of a collapsible boom, when inspecting the alignment bushings. These are the places that need to be lubricated.
Squeeze a small amount of grease onto a rag or fingers and work the shaft without skipping. It is applied in a thin layer, but everywhere. Special attention must be paid to the splines, because they are under the greatest strain, especially when the grasshopper blade strikes rocks and other objects.
Insert the lubricated shaft back into the shaft with a slight twisting motion. This ensures that some excess grease remains on the centering bushes where it should be. Rotating will also help the splines get into their seats on the gears.
If you are servicing a straight mower with a non-disassembled boom, it is simply reattached to the gears. In the case of a two-piece boom, the short shafts are each inserted into their respective halves. Then the shaft sections are centrally aligned. If their splines do not get caught, you can simply twist the lower gear by hand. The docked boom is then clamped back together with the coupling.
In infrequent use, this maintenance should be done every season. The grease used for CV joints withstands high temperatures well, which eliminates oil drips when the grasshopper is in use for a long time. The same compound can also be used to lubricate gearboxes. It can be pressed into them with a syringe, if the tube does not have a spout. The frequency of lubrication of the gearboxes is higher than the shaft. Usually manufacturers recommend doing this every 5 moto-hours.
What lubricant should be used for the grass trimmer gearbox?
During operation, the mechanical part of the grass trimmer is loaded with contact forces on the tines, resistance reactions from grass clippings (sometimes. with dirt), dynamic, shock loads due to constantly changing torque. Grass trimmer gear lubricant must fully take into account these features, so the brand selection must be strictly individual.
The following factors are taken into account:
- Manufacturer’s brand. Every brand is not unreasonably focused on lubricants of its own making (we can talk about cheap Chinese products later). This includes manufacturers such as Husqvarna, STIHL, Huter, Makita and others. Russian-made grass trimmers are an exception: for example, Kalibr does not specify the lubricant brand in the user manual at all.
- Grease viscosity. 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 gearbox component surfaces, as a result no grease is squeezed out into the gaps or out of the unit.
- Intensity of grease consumption by the gearbox. Here we have to focus on our own experience and the recommendations of experts, as some trimmer manufacturers, relying on the presence of their own service centers, do not give clear recommendations regarding the period of operation of the reducer between two lubrications at all.
Take a syringe and temporarily remove the piston. Put grease in the cylinder. Usually the amount is 5-10 g (more exact info about lubrication can be found in the instruction manual of the brushcutter).
Don’t be lazy to spend a few minutes after buying your brushcutter and before mowing season to lubricate this important assembly. And your tool will always be ready for use at any time and will last for many, many years.
Disassembly and lubrication
First you need to disassemble the boom. With a conventional chain saw, all you have to do is disconnect it from the upper and lower gearbox.
If the grass brushcutter has a collapsible, two-piece boom, it’s even easier. It is only required to remove the coupling in the center and separate the halves.
After disassembly, the 2 shafts will fall out easily, and you do not need to remove the housing from the reducers.
If the grasshopper has already been in operation, when you examine the shaft, or shafts in the case of the collapsible rod, you may notice scuffs from the alignment bushings. Those are the places that need to be lubricated.
Squeeze a small amount of grease onto a cloth or your fingers and work the shaft without skipping. It is applied in a thin layer, but everywhere. The splines need special attention because they are under the highest strain, especially when the blade of the brushcutter hits rocks or other objects.
The lubricated shaft is inserted back into the boom with a slight twist. This keeps some of the excess grease on the alignment sleeves where it needs to be. Rotating also helps the splines get into their seats on the gears.
If you service a straight mower with a non-disassembled boom, it is simply reattached to the gears. With a double-unit boom, the short shafts are each inserted in their respective halves. Then the parts of the boom are centrally aligned. If their splines don’t get in, you can just twist the bottom gearbox by hand. Next, the docked boom is clamped back together with a coupling.
With infrequent use of the lawnmower, this maintenance of the boom should be done every season. The applied CVT gear lubricant is designed to withstand high temperatures, so it does not drip oil when the grass trimmer is in continuous use. The same compound can be used to lubricate gears. It can be pressed into them with a syringe, if the tube does not have a spout. Gearboxes are lubricated more often than shafts. Usually manufacturers recommend to do it every 5 hours.
Grass trimmer gearbox design
The gearbox of the grass trimmer is the component that transmits the rotary motion of the engine shaft to the blade or the brushcutter. It is located at the lower end of the brushcutter bar. Gearbox is also designed to reduce the engine speed of the grass trimmer.
The gear train consists of several gears, which rotate at high speed, depending on the brushcutter model. As a result, they get hot because of the high friction. If there is insufficient or no lubricant, the process leads to severe overheating and failure of parts, and therefore the need for a complicated repair. To avoid this, it is necessary to timely lubricate the transmission unit. The disassembled gearbox is shown in the photo below.
Gearboxes of modern trimmers of different models from different manufacturers differ from each other by design and the size of the seating. It comes in:
The most common diameters of round seats are 24, 25,5 and 26 mm.
Mowers are equipped with gearboxes with different types of gears:
The drive shaft and gearbox. these are heavily loaded assemblies of the grass trimmer, which are highly susceptible to wear. Between them, the motion is transmitted because of the clutch of the gear teeth, located at different angles to each other. Gears work effectively only if there is no mechanical damage. The mechanism should not overheat, otherwise it can jam.
How to lubricate the gearbox of the grass trimmer? Grass trimmer lubrication points
Proper maintenance is the key to long and reliable operation of the tool. Primitive maintenance operations include timely lubrication of the gearbox and cleaning the grass trimmer filter. And what to lubricate the grass trimmer gearbox, every user should know. Cleaning is carried out in several stages:
- After removing the hood, the element is removed.
- Then it is flushed with gasoline and dried (naturally).
- Clean the filter area from oil residue and dust.
- Checking the boom for rotation during operation.
Is it possible to grease the gearbox of a grass trimmer with solidol, if no other means are available?? No, for long life, the manufacturers recommend the use of specialised lubricants. Some manufacturers develop care products that are adapted directly to the branded tool. To lubricate the working pairs, you only need to unscrew the plug and pour the liquid into the container.
The process of lubricating the gearbox
Gearbox is a mechanical device that is designed to transmit torque from the engine to the cutting equipment. Located at the bottom of the grass trimmer.
Immediately before maintenance work, remove the electrical cap (or plug from the spark plug). Do not turn the trimmer upside down to avoid fuel leaks. To replace the grease, disassemble the unit.
The disassembly process consists of the following steps:
- Loosen the side screw.
- If there are no traces of lubricant, it should be added (3-4 grams).
- Next, the gear is cranked by hand. This is to distribute material evenly on the gears.
The operation is carried out several times. The assembly should fill tightly with grease. At the end of the operation, the screw is put in place and tightened tightly.
To lubricate the grass trimmer gearbox, it is necessary to clean the plug and the place around it from contamination, and then unscrew it. the lawnmower is laid on its left side. Rotating the gear mesh, at the same time the grease is added to the gear housing until it fills up.
How to choose the right lubricant
During operation, the mechanism components are loaded with contact forces on the teeth, resistance reactions from debris, as well as dynamic and shock loads. Depending on the characteristics of the load, you should choose what to lubricate the gearbox of the grass trimmer.
The selection should take into account such factors:
- manufacturer’s brand;
- Viscosity of the grease (the selection of this parameter depends on the torque of the shaft);
- adhesion to the surface of the parts of the node;
- Intensity of grease consumption (ambient temperature, type and volume of work should be taken into account).
If a suitable lubricant is not available, an all-purpose grease can be used. The latter must contain some components:
- anti-wear additives (without toxic lead);
- mineral oils of high purity (inorganic);
- Solid lubricants with graphite or molybdenum disulfide.
Greases of different consistencies are used for caring for mechanism units:
- Semi-fluid. Such compositions contain a variety of additives and admixtures.
- Plastic. STIHL grass trimmers are the most universal of all variants. Mostly used for gear and screw drives.
- Solid. Plate slurries in their original state.
Special gear compound refers to the semi-liquid system.
Popular is the grease for the grass trimmer “STIHL”. Thanks to the special composition and components, significantly reduces wear and increases resistance to corrosion. The main properties of the lubricant of this brand are:
STIHL grease is suitable for brushcutters and trimmers, as well as all transmissions with closed housing.
Faults and solutions
- High (or rapid) heating. The main reason for this is a lack of lubrication. If this occurs, add lubricant and run in at a low temperature.
- Increased vibration, gear shakes.
Places to lubricate the grass trimmer
Careful inspection and maintenance is necessary for smooth operation and a long service life of the mechanism. Lubricating moving parts is important. In most cases, these are:
Popular among users is the multipurpose water-resistant grease “Lithol-24”. Operating temperature range. from.40 to 120 degrees. This grease is used in friction units and is effective at higher temperatures.
Properties of trimmer grease
Special substances are used in the production of grease, which must meet environmental norms and standards. After use they decompose without harming the environment.
The material consistency is initially of a high viscosity level, and this parameter decreases during operation. This factor ensures full penetration and reliable protection of working steam in heating conditions.
Longer use and trouble-free operation is ensured by timely and proper maintenance. Different materials are used for maintenance operations.
Renowned manufacturers develop their own branded care products. These include: lubricant for trimmers “Husqvarna”, “Champion”, “Makita” and others.
The gearbox of the gasoline grass trimmer is lubricated after every 8-10 working hours.
User feedback on lubricants
Experts advise to use only original materials, the characteristics of which meet the requirements of the manufacturer. If there are none, you should clarify than to lubricate the gearbox of the trimmer for grass.
Experienced users do not recommend using solidol, because this material is not suitable for the temperature and speed characteristics of the node, as well as the consistency.
Also given material does not have antiwear properties.
The working temperature range of solidol. from minus 40 to 65 degrees, but even at such parameters in the process of heating density of the material increases, and the grease itself becomes coarse. In the event of an emergency, “Lithol-24” can be used on the tool.
Servicing a gasoline grass trimmer
Most brushcutters and trimmers have a flexible shaft. Its condition should be checked at least once every 50 working hours. To perform this operation, you must remove the boom tip, pull out the shaft and inspect it, then lubricate.
For the care of the shaft is suitable for inexpensive materials, it is more difficult to find them for the trimmer gear for grass. What to lubricate this mechanism with. depends on the company-manufacturer of the tool. It is best to use materials that contain molybdenum disulfide. The latter provides smoothing and filling cracks in the working surface, so it is especially valued among users.
Important: Using too much grease with high density leads to overheating of the mechanism, increased friction of the working pairs and fuel consumption. This is why materials and preventive maintenance have to be carried out responsibly.
