Lubricant for a trimmer gearbox for grass

For a long time, to trim the lawn, they do not use such a tool for pumping grass as an ordinary braid for grass. Of course, this instrument remained in the villages, but in a country house or in the country in order to dig a lawn or a lawn overgrown with grass, overgrown with grass roadsides, use a trimmer for grass. This is a type of garden tool that combines a braid and a lawn mower.

Trammers for grass are different, but basically they can be shining to three types. These are gasoline, with electric drive and receiving power supply from the battery.

The most powerful motorcycles with a gasoline engine are considered. They are considered a professional tool, are used not only for Luja at the house, but also by employees of the housing office and road administrations to bring the territories covered with lawn in order. The engine of this tool with high power, usually there is air cooling. Having behind the back in the backpack the capacity with gasoline and oil for the engine, the working is not tied to the place and can process large areas at a considerable distance, and with a fairly high speed of work.

Gasoline trimmer for grass in work

Of course, such a tool also has its own shortcomings, for example, a large number of exhaust gases, a big noise that is heard with the windows closed, when they mowed the grass on the street. If, for example, that either from the elements of a trimmer for grass will fail, it will be difficult to make repairs without experience yourself. In addition, it has a large, relatively weight, it will be difficult for a woman to work with him, and the price is much higher than other types.

A tool with an electric engine, with a power supply through an electric cable, a less powerful tool. It has the upper location of the engine and the lower location. Both models have both their advantages and their disadvantages. Due to the binding to the power source, it is used in personal farms, though you have to equip the device with an extension cord.

Trimmer for grass with power cable power

But they are more convenient in work and have a little weight. In addition, the noise level and vibration level are small, although they will not work to mow thick stems of plants. Easily repaired and serviced. Affordable prices.

The third type of trimmers is battery. They do a great job with work where it would be impossible to approach a mower with a cable, comfortable in work, they can be easily transferred from place to place, they will not be confused in the wire and will not interfere with it. Work quietly, inexpensive.

Bosch.Battery trimmer

There are difficulties in their work, it is constantly in need of recharging the battery, the smallest power compared to other types. Therefore, they are bought as an addition to two other tools, and the choice of models is not so big.

Dismantling and replacing the gearbox

Due to various types of gears, shape and size of the seat, the interchangeability of gearboxes is possible in rare cases. Therefore, when purchasing a new detail, you should take into account the model of the old node and the brand of the trimmer for the grass. In the event that you still need to use a non-original device, it is necessary to choose it taking into account the following nuances:

If the listed parameters are the same, the old gearbox is allowed to be replaced by a suitable non.Original part. And to replace, you need to remove the gearbox from the bar and disassemble. To do this, you will need to weaken the fitting bolts located under the design and remove a pair of corkscrew rings using round.Drawers, and then remove the bearings from the driven and the leading shafts using a special puller. And to collect the mechanism, you need to install the removed parts in the reverse order.

Advice! In the absence of a puller, bearings can be carefully knocked out with a hammer and a wooden bar. Blows must be applied carefully so as not to damage the seat. However, it is impossible to crank up the cloudy parts, therefore, to extract them, they need to be warmed up using a construction hairdryer (the temperature is 600 ° C).

How to Oil lubrication in gear box

The assembly of the gearbox is easier than disassembly. Parts of the structure are installed in their place with the help of light beats of the hammer. When the device is assembled, you need to make sure that the driven shaft is freely cunning if you move it in motion.

The reducer lubrication process

A gearbox is a mechanical device that is designed to transmit torque from engine to cutting equipment. How to lubricate how to lubricate a trimmer gearbox for grass is also an upper gearbox. Located in the lower part of the trimmer for the grass.

Immediately before preventive work, an electric cap (or a plug plug) should be removed). It is forbidden to turn the trimmer for grass to avoid fuel leakage. To replace the lubrication, disassemble the device.

The disassembly process consists of the following steps:

  • The side screw is twisted.
  • If there are no traces of lubrication, then it should be added (3-4 grams).
  • Next, the transmission is scrolled manually. This is done for uniform distribution of material by gears.

The operation is carried out several times. The knot should be tightly filled with lubrication. At the end of the operation, the screw is installed in place and tightly delayed.

To lubricate the gearbox of a trimmer for grass, it is necessary to clean the cork and the place around it from pollution, and then unscrew it. The lawn mower is laid on the left side. Rotating the gearing, at the same time added lubrication to the gearbox body until it is filled.

The main malfunctions of the gearbox and ways to eliminate them

With a gearbox of an electric or gasoline trimmer for grass, various breakdowns occur. The most frequent of them are presented in the table further. There you can also find the reasons for their occurrence and methods of elimination.

Reducer malfunction Possible causes of breakdown The method of elimination
The gear node is heavily warmed up the use of unsuitable (low.Quality) lubrication or its absence you need to replace or add lubricants
The gears are new and did not get sick It should be worked for a short time for a time without strong loads with regular stops so that the mechanism manages to cool
shaking of the shaft during rotation, the appearance of backlash and knocking destruction or significant wear of any of the bearings replace the failed bearing with a new
The transmission mechanism flies from the rod of motorcycles or stagger Damage to its body It is necessary to replace the part
In some cases, with minor damage, a clamp made of metal, a place with a fault is carried out
not fixed on the pipe wear of the docking area you can make a winding from the insulating tape at the mounting site or change the bar
The output shaft with a knife does not rotate or stops in case of an increase in the load wear of the teeth on the gears or one of them It is required to replace the interacting pair of worn details

Bearings are destroyed due to the use of inappropriate lubrication or due to its absence. Their damage is also caused by severe operating conditions of motorcycles and the ingress of extraneous particles of the material (for example, broken metal teeth of mechanical transmissions) due to the fact that the integrity of the anthers is violated.

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 mentor. In this case, work should be carefully so as not to damage the seat. Using the pre.Heating method to shoot the bearing is not recommended. This is due to the fact that the metal may lose the required operational characteristics.

If the knife ceases to rotate under load or stands still, then this is accompanied by an uncharacteristic sound.

Most gearboxes can easily be eliminated with your own hands. Replaced details are recommended to purchase “relatives” designed for the used motorcosa.

Characteristics and use on the car

The main functions of the lubricant for bearings

The use of lubrication has a certain goal:

  • Decrease in friction and, accordingly, wear of the contacting surfaces of parts.
  • Increasing the sliding parameter of surfaces during deformation due to the occurrence of the load.
  • The formation of an oil film, mitigating shock loads during operation.
  • Uniform distribution of heat generated during the friction process.
  • Corrosion protection.
  • Obstacle to the penetration of dust and other pollution.

In order for the selected lubrication of rolling bearings to meet the above requirements, it is necessary to take into account the operating conditions of the machine or mechanism.

Lithium lubricants

The main specifics of lithium lubricant for bearings is its high water.Repellent properties. The lubricants of this group have high viscosity, characterized by one of the broadest operating temperatures. For this reason, lithium lubricant is considered the most universal and is used in many nodes of mechanisms and machines.

How to lubricate the motorcosa gearbox

Bearings for magazines and other sliding contacts of lubricant are used for pins, bushings, sliding contacts, as well as for sliding bearings experiencing shock loads, frequent launches and stops or reverse direction. In such cases, the lubricant provides a thicker lubricant than oil, and protects against wear during boundary lubrication.

The lubrication used in the sliding bearing should be periodically replenished. The frequency necessary for regeneration depends on the effectiveness of the lubrication of consistent lubrication, its thermal stability and the speed with which wear is formed. The bearing temperature has the most powerful effect on the lubricant service life. As in the case of ball bearings, higher temperatures increase the velocity of oil loss from the lubrication structure due to oxidation, leakage and evaporation. With drying, the lubricant tends to condensate and loses the ability to distribute in the bearing and replenish the border films.

This lubricant is made as a mixture of synthetic materials and mineral oils. Different organic and inorganic substances are used as a thickener. With an increase in the number of bearing speeds, the viscosity of the substance decreases. Of the most famous lithium lubricants, such popular materials as CIATIM-201, 202, OKB 122-7 can be noted. Closed bearings are widely used by the CITIMI-203 and VNIINP-242.

Figure 1 shows the recommended continuous operation times for applications such as sliding bearings in farm and construction machines, depending on the temperature of the bearing. 4. Another problem with a heavily loaded design. Their oscillatory nature of the work. A condition that can be stronger than continuous, unidirectional speeds characteristic of most machines. There may be a problem with damage or disruption. Experiments show that the friction coefficient can suddenly increase after several cycles with a slight warning.

At home

The consumable is lubricated with bicycle chains, locks, door loops of apartments, garages, as well as cable brake system drives. Due to the density, the lubricant can be mixed with solvents. As a result of this, the substance falls into hard.To.Reach places. After application, the solvent evaporates, and the lubricant remains. The product can be used in the processing of rubber and plastic parts, as well as surfaces impregnated with paintwork.

Place of grease of a trimmer for grass

For uninterrupted 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;
  • The joint of the direct shaft with flexible;
  • The transition of the shaft with the landing head;
  • Gearbox.

Popular among users is a multi-purpose waterproof lubric “Litol-24”. Operating temperature interval. From.40 to 120 degrees. This lubricant is used in friction nodes and is effective at elevated temperatures.

How much lubrication should be used when replacing in the gearbox angular grind

If the amount of lubricant in the bearings is controlled by flowing it from the back, then a certain amount of grease is filled into the angular grinder gearbox. Excess lubrication will flow out during operation. And its small amount will not provide high.Quality gearbox work.

In the gearbox, you need to leave as much lubrication as it will be required to be covered with teeth of the gears.

For a guideline, apply so much lubrication so that it occupies a little less than half of the reducer cavity volume.

We unscrew the side screw on the motorcosa gearbox. Depending on the company.Manufacturer of a garden tool, instead of a screw for a hexagon, there may be a turnkey bolt, more often at 17. The thread is ordinary, unscrew counterclockwise. Do not lose the sealing puck.

If the lubricant is not visible on the internal end part of the screw, then it is necessary to add 3. 4 grams. Scroll through the gear with your hand, changing the direction of rotation, so that the lubricant is distributed along the gears.

Repeat the operation several times. On average, about 5. 10 g enters the gearbox. The node should be completely filled with grease, taking into account the installation of the screw.

Then set the screw in place, tightly tightening it.

As you can see, to lubricate the gearbox on a motorcycle, you do not need a lot of time or special skills. We usually gather longer than we carry out the entire volume of preventive work.

Lubrication for the gearbox of popular brands of trimmers

Famous firms produce their own production:

  • For gearboxes, Motokos, the manufacturer of the StiHL brand recommends using the STIHL Superlub FS transmission lubricant, is available in tubes from 250 g to 80 with a special pointed tip for convenience, has silver.Orange color;
  • The manufacturer recommends the motorcade gearbox to serve the lubricant of its own production based on lithium components in the name of the Arsenal AR-417;
  • Huter for its products offers a rezoil plastic universal lubricant, cyatim, you can also apply all the above lubricants;
  • In all cases, it is necessary to monitor the state of the gear node, lubricating it no less than once a month. At the same time with lubrication of gears, you can grease the drive shaft itself.

How to lubricate an underlying gearbox, you can find out by watching from the video below.

Serving gasoline trimmer for grass

Most motos 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 tip, pull out the shaft and inspect it, then grease it.

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

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