Complete disassembly of the gearbox Motokos for removing wear of wear and lubrication products

How to lubricate pushing the repair of the gearbox Motokosa? Whatever the brand of motorcycles, the second most importantly after the engine is a gearbox, consisting of two braids of gears, the smaller of which is the leading, the large one is the driven.

The gearing rotating in the bearings is located in the case consisting of two symmetrical halves, and, tightened by each other. The lead gear receives rotation from the engine on the rod, which ends with the slots (usually 7 or 9), the led transfers rotation of the spindle, which serves to plant the working body. a drum with fishing line, cables or cutting disk. The gear bearings from the spindle side are closed by the omentum that protects the supports and grease in them from pollution. To replenish it, a bolt is provided on the case, unscrewing which you can add grease during the operation of the tool.

Regular lubrication of gear gearbox Motokosa is so important that it is worth talking about this separately. If we exclude work with cutting disk, when it clings to a stone or a border and sends an oncoming shock impulse to the gearbox, which leads to a breakdown of the tooth of a driven gear, parts of which gradually spoil all the clutch, the lubricant can delay the repair of this important unit and extend the service life of the service in several once.

Dismantling the gearbox to check and replace lubrication and particles of wear

To do this, disconnect the casing and a bar with a shaft inside the gearbox. We remove the working body from the spindle, and wash the gear knot so that it is more convenient to disassemble. We unscrew the bolt, but it can be left in place, t. to. He does not carry any power load.

Then we remove the lead gear from the body. To do this, with the help of a special pull.up, we remove the locking ring from the ring slot, which holds the block of the drive gear in the right position in the case in the case.

Since bearings are installed in the nests with an interference with their outer ring, it is not easy to extract them. To facilitate this task, we heat the gearbox in the area of ​​bearings with a construction hairdryer.

As soon as the metal metal heats up, it will expand, and the tightness will disappear. Now you can easily extract from the body a block of the leading braid of a gear with two identical paired bearings.

We proceed to the extraction of the Bloc’s gear gear with the spindle from the gearbox. Here, first, we remove the centering sleeve with plots with narrow sponges, then the oil seal, pushing it with a screwdriver or some other tool suitable for this.

As well as in the first case, we pull out the holding part by squeezing it with the help of the locking rings, using the holes in the castle for this.

We heat the gearbox body with a hairdryer in the area of ​​the bearing of the bearing of the block of the driven gear and after a while we pull it out, slightly pulling the spindle.

Echo SRM-2305 Si lawn mower

The Echo SRM-2305 SI lawn mower is a light and compact device for mowing grass in small areas. The power of the two.stroke engine is 0.77 liters.With., But this does not affect the quality of work, the unit copes with the task perfectly.

The convenience of operation is achieved due to the bicycle handle. It is a regulated type, so it is very convenient to work on it, and most importantly, you can configure it for any operator. The weight of a trimmer for grass is only 5.4 kg, so it is comfortable in operation.

To mow grass, you can use a reel with a fishing line, but it is best to install a knife for mowing a young shrub for mowing.

For additional convenience, you can use a shoulder belt that comes in the kit. With its help, the entire load is evenly distributed and fatigue is not felt even after some time. In the Trimmer Echo SRM-2305 SI, a system of extinguishing vibrations is installed and the level of noise is significantly reduced.

Advantages of the Echo SRM-2305 SI model:

• Available components;
• Mobility in operation;
• Reinforced gearbox;
• The trimmer is easy to process complex areas;
• Small fuel costs.

Replacing the lower gearbox Motokos (trimmer for grass)

There are no eternal tools, even the highest quality fail. This is due only to mechanical damage during operation, but also with metal fatigue. Even under normal operating conditions, microcracks appear in it, then increasing to critical sizes. Replacement is required with the wear of the bearings. The most loaded element of the tool is the lower gearbox.

Tools

You will need a set of heads and a narrow flat screwdriver. The size of the keys depends on the manufacturer of the trimmer for the grass, and the screwdriver should be included in the technological hole located in the lower part of the gearbox body.

First, the coil with a fishing line should be disconnected from the gearbox. It is driven on the threaded part of the gear of the mechanism. Tightened with a hand, and further clamped under the influence of the moment of inertia during the operation of the scythe. This means that there is no need to use any devices for unscrewing.

Insert a flat screwdriver into a special technological hole, slowly scroll the coil until its end falls into the deepening of the slots.

With one hand, firmly hold the screwdriver in the chosen position, and unscrew the part in the direction opposite to rotation. There are gearboxes with a special through hole for disassembly, they are easier to change.

The gearbox to the bar is attached to two bolts. One fixes it in the center, and the second clamps and does not allow displacements during operation.

For two to three turns, weaken the clamping bolt. Remove the lower gearbox, it will come down much easier if you constantly turn the body in different directions.

In the same algorithm, insert a new one in place, combine the holes in the case and the bar. Insert the corresponding bolt, then tighten both the marking on the gearbox.

Put a flange on the rifle slots for the rush of the coil, tighten it. The flange not only rotates the cutting element, but also protects the gearbox from dirt getting.

How and how to lubricate the shafts in the rod of motorcycles

Many new motorcycles, even sold in collection, do not have a lubricant on the shaft of the bar. As a result, it warms up, wears out, a light whistling rattle is gradually added to the sound of a working motor and vibration appears. To protect the technique from premature wear, it is enough to devote 10 minutes and just grease the shaft.

Materials:

First you need to disassemble the bar. In a conventional benzos, it is enough to disconnect it from the upper and lower reducer for this.

If a braid for grass has a collapsible bar, consisting of two parts, then it is even easier. It is only required to remove the connecting coupling in the center and dilute half.

If the braid for the grass has already worked, then when examining the shaft, or shafts in the case of a collapsible bar, you can notice scuffs from the central bushings. Such places and need lubrication.

A small amount of lubrication must be squeezed on a rag or fingers and process the shaft without passes. It is applied with a non.weed layer, but everywhere. Particular attention should be paid to the slots, since they are on the highest load, especially at the time of the knife of the knife braid for grass on stones and other objects.

The greased shaft is inserted back into the stack with a slight scroll. Thanks to this, part of the extra lubricant will remain on the central bushings, where it should be. Rotation will also help the hills to get into their seat on the gearboxes.

If a straight lawn mower with a non.vegetable bar is served, then it is simply attached back to the gearboxes. In the case of a two.part bar, short shafts are inserted into each half. After this, part of the rods join the center. If their slots did not hit, then you can simply twist your lower gearbox with your hand. Further, the jointed rod is clamped back with a coupling.

If the lawn mowing is inflow, such a rod maintenance should be carried out every season. The cord’s lubricant used well withstands high temperature, which excludes oil stoops with long operation of braids for grass. The same composition can also be used for lubrication of gearboxes. In them it can be pressed with a syringe if the tube does not have a nose. The lubrication frequency of gearboxes is higher than the shaft. Typically, manufacturers recommend this every 5 mothers.

The trimmer for the grass is very hot

Overheating of a trimmer for grass can occur for many reasons:

• Gasoline has not the same octane number indicated in the instructions for the unit;
• the proportions of gasoline and oil during the preparation of the fuel mixture are not observed;
• A mixture of fuel with butter has long been prepared (the mixture cannot be stored for more than 2 weeks);
• The trimmer for the grass works more than the time instructions;
• A low.power trimmer for grass on thick and hard grass is used, the device works with overload and quickly heats up;
• shifted towards the bar or the cassette lid clutched.

The latter occurs if you install a mowing head inappropriate for this unit, or when the axis shifts inside the bar. These changes make it difficult to rotate, the load on the engine increases, and it overheating.

The principle of operation of the carburetor of the lawn mower

The throttle dashes determines the amount of air for supply, and the engine power directly depends on this.

Fuel is sucked into the carburetor system (its membrane). Then passes through the fitting in the carburetor. Next, the liquid moves through the intake and exhaust valve of the pump. Filtered with a net. The needle valve moves into the membrane chamber.

Repair of a trimmer for the grass Echo SRM-22 GES, replacement of a carburetor.

• Air supply to the tube with an air septum (damper). The partition regulates the intensity of the air flow.
• The fuel supply system is necessarily narrowed by a diffuser to increase the flow rate.
• Gasoline through the float chamber and nozzle with narrowing. The chamber with a float regulates the temporary volume of gasoline. In the float chamber, the pressure level is neutral, and in the tube with narrowing is already low. Thanks to the pressure drop, fuel penetrates through the jetler.
• Air flow acceleration contributes to the transfer of fuel (gasoline) and its spray. As a result, the air-fuel mixture of the necessary proportion or density is formed.
• The air-fuel mixture penetrates the engine cylinder through the fuel tube.

The level of air density in the system depends on the area of ​​the open air damper. The wider the damper is, the greater the fuel consumption and power.

Simply put, adjusting the carburetor on a benzocos. creating an optimal fuel mixture due to the correct air supply.

The main problems and malfunctions of the carburetor.

Mesh filter. There are only two tasks with this element more often:

In order to find out the cause of the breakdown, the fuel filter lid is unscrewed to extract the mesh filter. If the mud just accumulated on it, then flushing in gasoline or purge will help.

With visible damage on the mesh filter, it is necessary to put a new. There may also be damage to the fuel supply pipe (during the repair they practice checking this element).

The starting device of the carburetor almost always does not work due to blockages. Should be used for flushing acetone or the same gasoline.

Purging parts of a carburetor with click of compressed air. permissible and comfortable repair practice.

The hull of throttles, places of ligaments of the parts of the carburetor, intake or graduation pipeline. all of the listed parts are subject to depressurization. You can probably check the simple method. spread the problem area with soap foam.

Washing with partial disassembly

The process of washing the carburetor with its partial disassembly is considered using the Solex carburetor and the Jet 100 Ultra carburetor. You don’t need to buy a lot. One can be enough with a volume of 200 ml. In addition to special fluid, you will also be required:

• set of wrenches;
• Cross and slotted screwdrivers;
• Passatigi;
• a capacity with a wide “throat” with a volume of 2-3 liters (for soaking the carburetor cover);
• a capacity with a wide “throat” with a volume of 0.2–0.5 l (for soaking small parts);
• kerosene (purified gasoline, acetone);
• tire pump or compressor with a tapering tip;
• toothpicks;
• Old toothbrush;
• pure dry fabric that does not leave the pile (better rough);
• Small wooden blade (like ice cream sticks).

Flushing the carburetor without removing it from the engine and disassembly

• We go to the nearest gas station.
• Unscrew the fuel tank plug.
• Open a jar with flushing liquid (opens like a beer bank).
• Using a watering can, pour the product into the tank.
• Pour gasoline into the tank (until complete);
• We drive by car until the fuel is over.

According to the manufacturer, the Hi-Gear HG 3205 additive helps not only self-cleaning of the fuel system, but also helps:

Maybe, of course, everything is not so colorful, but having drove 300-400 km on this additive, you will notice positive changes in the engine operation. To maintain the fuel system and carburetor in particular, it is recommended to repeat the described procedure every 3000 km of run.
