How to disassemble the gearbox of Fortun.

Motoblock repair: with your own hands, MB-1, gearbox, carburetor, regulator, checkpoint

The MB-1 motorblock gearbox is the basis on which other nodes and motor block units are mounted. Therefore, to carry out the repair of the gearbox with disassembly, it is necessary to disassemble the single.axle tractor, for which to dismantle the engine, the steering column, the pallet, the brackets with the pulleys of the front and rear strokes, the gearbox pulleys, the wheels. Before disassembling the gearbox, clean it from dirt, drain the oil. Remove the rotating head from the gear handle, knocking out the pin holding it with a thin pier. Turn out the stop screw 11 and remove from the switch shaft 7 sleeve 9 and the spring 10 latch. Turn away the bolts 17. fixing halves of the case, then bolts 7 (2 pcs.) and 10. Put the gearbox on the left half of the case, with the help of a thin screwdriver or knife carefully so as not to damage the gasket, disinse half the gearbox and remove the right half. Leave the sequent washers of the fold bolts on the block-star. Note. It is recommended to remove only defective parts from the gearbox without disassembling the gearbox completely. To disassemble the gear shift mechanism, remove the lock ring b from the switch shaft, providing the free stars 31. 32 Take the Schplint 3 from the threaded part of the handle 1 switch, turn it out (counterclockwise) from the cracker 8 and remove the handle and cracker from the shaft. Rinse the removed parts, replace defective. Switch cuffs replace after removing it from the gearbox. Collect the gearbox in the reverse order. To the docking surfaces of the hull halves, apply a thin layer of sealant. Connection of the hollows of the body start with the central fitting bolts 7 and 10. Then the halves fastening bolts, starting from the middle part of the gearbox with the sequential transition of the tightening of the bolts to the edges. Before the final tightening of the bolts, check the smoothness of the moving parts of the gearbox.

The gearbox began to flow on the output shaft. I looked and on the shaft of the backlash there is a replacement of cuffs for a long time will not help. It was decided to finish working out in the box until the end of the season.

Split the gearbox and the result on the face. In the oil at the bottom of the gearbox there is a metal shiny dust.

Full.sized gearbox with gears of the box. From the box, only the output shaft with bearings was dismantled. The rest did not dismantle because there were no problems in the box. The full size is empty (second half) full size and cuffs, a cap with a bearing 206 closed full size in the body full size of the cuff from the other side

Cuffs and bearings for replacement bought an infection, but when the gearbox was dismantled. The idea of ​​ball bearings appeared not designed for significant axial loads. Therefore, they do not live on this shaft for a long time when turning and cultivating arise axial and shock loads (forces).

The full size of the bearing shaft and possible options for replacing bearings are more reliable.

Here is the separator and the outer ring of the bearing burst.

The full size of which the outer rings burst? And what threatens? How to deal with it?

Therefore, I want to put roller or conical bearings as usual on the hubs of the wheels of cars. It will still be more arrogant, not 3-4 seasons (years), balls are nursing.

Full size bearings are better to put?

Only with conical, the problem is 1.25mm above the bearing is obtained (not 16mm, but 17.25mm). I think to put a 2mm paronite gasket in the plane of the gearbox connector. Trying the shaft by hand will spin or hold the bearings (bearings for the experiment used). Or anyone has other ideas for increasing places for bearings?

There were 6206 bearings on one side size (30x62x16), it is possible to replace without alterations by 102206 (single.roller roller.rolled) size (30x62x16) can be replaced with alterations by 7206a (conical collapsible roller) chaplain or luaz size (30x62x17.25). As soon as the gap? There is a nut for this on the hubs. And then somewhere 2 mm should be taken at least. Where to take 2 mm? I went shopping for bearings for reliable and durable. In stock was in Makeevka on Zelenny there are 12206 (single.roller roller core) and 1206 (two.rope self.supporting ball).

Full size1206 double.row ball

12206 (GPZ-10 g 480 for significant axial loads is not designed without a separator, and 1206 (China 280 rubles.) GPZ-8 g. Kharkov. 320 rubles. In theory, withstands axial loads and two rows of balls of self.established.

Full size1206 GPZ-8 g. Kharkov. 320 rubles. In theory, withstands axial loads and two rows of balls of self.established.

Took 1206 (2pcs.) 640 rubles. And do not redo anything and grind anything.

Full size of the bearing of the bearing

On examination, I found that the seats of the bearings were conducted in the places of welding to the body and, moreover, are glorified. The bearing is easy to sit down.

Full size of a place for a bearing.

Therefore, I decided to plant in the corps in an old grandfather way, laying down the cigarette paper. Paronite laying on one side put on a sealant. The output shaft rotates easily by hand.

Full dimensional grandfather’s method of planting a bearing on cigarette paper

I think to rinse after the assembly as a diesel fuel gearbox. Let’s see what happens from this. Now it remains to collect and wait for the start of the season, let’s see how it will work when loading will work.

R.S. APROM.by/. a good reference to bearings of any structures and sizes. The main thing is only in order to be in the store.

The presented material in this article is especially in demand for people who repair their equipment on their own. Next will be affected by the main “subtleties” regarding the repair of the motorblock gearbox. To move directly to the topic of repair, you need to understand the device of the gearbox. Looking in advance, it is necessary to say: the structure of the gearboxes of modern motoblocks is similar to each other, there are only minor differences in a particular model.

So that the question does not arise “How to disassemble the motorblock gearbox?”, You need to be familiar with all the details. We list the main details and components of any modern walk.behind tract: covers and pulleys; bushings with bearings; lever, axis and plug for switching; Primary shaft block with gear; The input and output shaft of the motorblock gearbox. Components: washers and seals; right and left semi.axis; clutch and plug; bracket and spring.

What are the breakdowns?

Most of the problems in the gearbox of a motor block arise due to overload. Such breakdowns include the sleeve of the bushings on the metal chain, which leads to the so.called “slip”. Also, the owners of the motoblocks very often discover interrupted bushings switching. In order to avoid such troubles, experienced owners advise switching speeds only during a complete stop of equipment, in no case on the go. In addition, a star break is considered to be a common occurrence. That is, factory welding is not enough for the star to withstand overload.

It is very simple to “get out” from this annoying situation, you just need to return the star to its original position and grab it with welding much better. Side loads lead to wear of the support washer, after which there is a fly from the bushings from the chain. In addition to all of the above, it is necessary to periodically check the oil level in the gearbox, as well as to replace it.

How to check the oil in the motorblock gearbox?

Track the amount of oil to monitor constantly. Otherwise, a negligent attitude to technology will lead to fatal consequences. Fresh oil is poured every 50 hours. Along with this, excessive loads should be avoided, which ultimately lead to quick production of mechanisms and components. Let’s move directly to the change of oil:

  • Install equipment on a flat area. Find a probe 70 cm long.
  • The probe bends and is pushed into the opening for the filling of the oil to the stop, after which we take out the rod.
  • Observe the level of oil, which should be at least 25 cm. 2 liters of oil are added to a dry gearbox, a minimum of 1.5 liters.

Pully oil should be Gostovsky. It is pointless to use cheap oil, because sooner or later, it will cause breakdowns inside the motor block gearbox.

Repair of the motorblock gearbox

Complex technical devices, even if high quality assembly and components, eventually become unusable. The motoblock gearbox during intensive operation for a long time requires repair work, otherwise the device will not work correctly.

Reducer device for a walk.behind tractor

Before finding out how to repair the motorblock gearbox, you need to familiarize yourself with its design in more detail. It is one of the most important elements of this agricultural device. It is designed to transmit rotational movements from the power unit of the device to the equipment used.

The standard gearbox of the Chinese motor block or its domestic counterpart provides for the presence of the following nodes:

It should be noted that most of the models presented on sale can be divided into 2 groups according to their maintainability. The first is budget devices that differ in a short service life and low quality components, which makes repair of such equipment inappropriate.

The second is the collapsible structures of various price segments, which, thanks to their features, allow us to quickly perform defect and replace the spoiled part. It should be noted that after the repair, a high-quality gearbox is able to last several years without any complaints.

Classification of gearboxes

Many models of this node are presented on sale, in connection with which there was a need for their classification. Existing types of converters differ significantly from each other in type of structure and the main working elements. The most popular among consumers are considered:

  • Chain models. Provide for the use of one or more circuits as a transmitting node. The leading elements are a large and middle star. Differs in a simple, reliable design;
  • reversible devices. Equipped with a reverse mechanism, but are not capable of high speed;
  • belt equipment. The simplest, affordable products. For transmission of movement, a belt is used, as well as the pulley on which it is fixed;
  • gear gearbox. It is universally used in structures of heavy agricultural machinery, is characterized by low noise during work, modest dimensions and a long service life.

Often in homemade devices, a worm.type motorbactic gearbox is used, which has become widespread due to an impressive working resource, high reliability even with intense loads. The angular gearbox has similar advantages, the load on which directly depends on the quality of the lubricant, as well as the temperature during operation.

Another popular option is lowering models that are designed to effectively reduce revolutions with a proportional increase in power indicators of technology. This is extremely important in cases where it is required to use hanging equipment at low speed, which will improve the quality of work.

Reducer malfunctions

There are many reasons that can lead to a breakdown of this important node, which will operate the motor block of various manufacturers impossible. Among the main malfunctions characteristic of various models, it is advisable to attribute:

  • oil flow due to a high degree of wear of the cuff;
  • unsuitable lubrication parameters;
  • the appearance of subtexts on the output shaft;
  • rupture of the star;
  • chain/belt cliff;
  • wear of the control of the control lever.

It is important to note that it is possible to avoid most problems, provided that the oil is replaced in the device. Standard engine oil is used for this purpose, which allows you to use the unoic tractor for many years without the need to repair.

Self.repair of the gearbox

The need to repair a gear biablip gearbox can occur for various reasons. The procedure for eliminating most malfunctions is extremely simple, does not require any special knowledge and skills. In most cases, the repair of the product passes through the standard algorithm:

  • Drain the oil is carried out with the subsequent cleaning of the node from pollution.
  • The cast.iron or other type of converter is disassembled, each part is inspected for damage, defects, excessive wear.
  • If problematic elements are detected, they will need to be replaced with new.
  • The device is assembled, the oil changes.

There are several typical problems that are most common among this kind of technique. First of all, this is a failure in sliding clutch, which is eliminated by replacing the spring and disks. If the device begins to issue significant noise during operation, most likely immediate replacement of oil, a gear mechanism is required.

How to change oil in a mechanism

One of the most important factors affecting the service life of the gearbox of various types is the presence of oil. It needs to be changed regularly, which will avoid most problems. To do this, adhere to the simplest instructions:

disassemble, gearbox
  • Place the gearbox in the working position under a slight slope.
  • Exercise control of the oil level. Normal indicators are 25-30 cm probe.
  • Place the one.axle tractor on the elevation, and then unscrew the cork on the body.
  • Wait for the complete drain of the oil into the container, pour the new with the help of the corresponding hole.

For operation, the products of most well-known manufacturers are suitable, as well as any other oil that corresponds to GOST-17479.

How to change the oil seal

Motoboglok owners often have to deal with a breakdown of oil seals. a simple malfunction that can be quickly eliminated. This will need to be performed by a number of simple manipulations:

Timely implementation of such a procedure is extremely important for the correct operation of the unit, since the malfunction of the oil seal leads to intensive flowing of oil, which can lead to more serious problems.

Non.mounted equipment

Cultivators and motoblocks Pubert stand out in the line of technology produced by a popular brand, a wide variety of possible aggregation options with hinged devices. Even light models work with some additional tools successfully. Professional and semi.professional versions are more widely possible.

The vario series is distinguished by optimal functionality. The applied attachment equipment. cummers, plows, potato.cuttings, metal soil.bearing, snowbrusher. In aggregation with the mini.tender, the Unine tractor Pubert Vario 60 SC3 is capable of transporting goods up to 450 kg. The great advantage of the Pubert Vario motor blocks is the ability to work on waterlogged and wet soil on rice growing and other crops.

The Pubert Transformer 60p TWK Unoa Tractor is rationally combined with hinged devices: polting polting, plow-dowel, metal primer, minipric, dump truck, haywater, potato-cumulator.

Transmission bell housing,toyota innova/fortuner manual transmission 1GD engine

The most functional are professional motoblocks. Pubert Quatro Junior 65b TWK with hinged tools can be operated throughout the year.

Maintenance, features of operation, malfunction and repair

The design of the Pubert motoblocks is distinguished by thoughtfulness, reliable work for many years without repairs. High assembly level, high.quality components, simple maintenance, excellent maintenance in case of wear of parts. thanks to these features, cultivators and motor blocks Pubert are deservedly considered by many owners the most reliable machines.

The technique consumes gasoline AI-92, AI-95, motor oil API SG, SAE 10W30, SH, SJ, SL. Lubrication of movable nodes and rubbing parts is carried out by universal waterproof lubricants.

Engines from well.known manufacturers installed on Pubert equipment are distinguished by impeccable quality and reliability. Therefore, the run.in the cultivators are in test mode for 20 hours in sparing mode. After that, fuel, oil in the gearbox and engine are replaced, further after 100 motorized hours. For a series of light models, the first oil change is produced after 6 hours, subsequently after 24 motorized hours.

Since the model range of cultivators and motoblocks of Pubert is represented very diverse with various options for functionality and combination with hinged devices, owners before the operation of equipment, it is necessary to familiarize yourself with the leadership, use the equipment in accordance with its capabilities.

The schedule of preventive work, the terms for replacing consumables, minor repair and elimination of simple malfunctions, data on the device of motoblocks and safety precautions are submitted in detail in the factory operating instructions:

MB-1 Uno-Totor: DIY DIY Dypery Instructions and Repair

Special equipment, such as a single tractor, is very useful in the household. Due to the fact that motoblocks are most balanced in terms of price ratio, costs and performance, they win a lot, both tractors and other special equipment.

With its help, you can perform a large number of different operations that take a lot of time and require a large amount of effort, when using manpower and simple inventory. All spheres where you can apply one.axle tractor no longer cause disgust and unwillingness to work.

In fact, all the work comes down to management. you just need to be present as a driver.

This applies to modern technology, so older models of motoblocks, because in decades their design, in general, has changed little. the weight has decreased, the variety of models has increased, more advanced materials for manufacturing are used.

But the frame, the location of the engine and the control method remained the same, the attachment equipment, in fact, also remains unchanged, the difference can only be external, in insignificant details.

Therefore, the good old motoblocks, the service life of which has been exceeded for thirty years still in the ranks, have been performing their work from year to year. But every year they are increasingly needed to repair and replace parts, nodes.

After all, any technique wears out and needs to be repaired

And this should be paid much attention if, for example, you make long trips with a loaded trailer. The jammed hub will not be a big problem, but the malfunction of a more complex part, such as the transmission, will be, to put it mildly, unpleasant

The device of the reck of motor blocks, Neva, cascade (MB-1)

REDs of motor blocks MB-1 “Neva” (produced earlier), MB-1D “Oka”, MB-1 “Cascade” (except for its individual modifications) have the same design shown in rice. 35.The gearbox body is steel, stamped, consists of two halves 2 and 22, fastened together through sealing gasket 3 bolts. Hugs 8 and 23 are welded to each half of the case, forming a loading frame of a walk.behind tractor.

How to check the oil in the motorblock gearbox?

Track the amount of oil to monitor constantly. Otherwise, a negligent attitude to technology will lead to fatal consequences. Fresh oil is poured every 50 hours. Along with this, excessive loads should be avoided, which ultimately lead to quick production of mechanisms and components. Let’s move directly to the change of oil:

  • Install equipment on a flat area. Find a probe 70 cm long.
  • The probe bends and is pushed into the opening for the filling of the oil to the stop, after which we take out the rod.
  • Observe the level of oil, which should be at least 25 cm. 2 liters of oil are added to a dry gearbox, a minimum of 1.5 liters.

Pully oil should be Gostovsky. It is pointless to use cheap oil, because sooner or later, it will cause breakdowns inside the motor block gearbox.

What and how much oil to fill

Many ignorant owners of special equipment are interested in the question of which oil is poured into this detail. Let us consider in more detail the criteria for choosing this component:

  • The composition must provide maximum viscosity so that all working nodes do not rub to each other;
  • This mixture should withstand an elevated temperature, since in the process there is a strong friction of the parts;
  • This component should have the necessary concentration indicators (maintain the composition for a long time);
  • The oil should not be compressed (the composition must have a high density).

Do not pour oil into the gearbox

As a rule, transmission oil is used for special equipment, which provides the best performance indicators for such mechanisms. The gearbox needs to fill this consumable in accordance with the level. The amount of fluid for each individual node differs.

Important! Oil in the REPRECTOR OF A SALUT MOTOBLOCK, or, as it is also called, a motorbike, you need to keep it at a level, but not allow this indicator to reach a maximum, otherwise there is a probability of depressurization of the device and fluid leakage.

Oil replacement in a walk.behind tractor

You can change this consumable material in the motorblock 5 on your own, for this it is not necessary to contact specialists. Let us consider in more detail how this procedure is performed:

  • First of all, it is required to warm up the mechanism so that the composition has a smaller density, and it could be easily drained;
  • After that, the device must be drowned and proceeded with the systematic replacement of the liquid in the gearbox;
  • Next, it is required to prepare a suitable transmission fluid, as well as an oil seal suitable for the device;
  • Next, you need to unscrew the oil cork and drain all the oil present in the mechanism;
  • If necessary, you can use washing to eliminate all impurities and dirt from the node;
  • Then a new composition is poured, and also subjected to mounting the oil seal (this is required to be done in accordance with the technology in order to maintain tightness inside the node).

After serving, it takes some time to run up without loading on the unit so that all parts can be lost with a new grease.

disassemble, gearbox

Important! If washing is used, then it is necessary to give the device to work for some time (usually about an hour) so that all the cloudy impurities are removed.

Repair of the CAIMAN cultivator gearbox with your own hands

Details: Repair of the CAIMAN cultivator gearbox with your own hands from a real master for Olenord.com.

To swim and saturate the soil with oxygen before sowing plants will help the CAIMAN cultivator. The equipment for the land work of the French manufacturer is equipped with Japanese four.stroke engines, economical, and with a large capacity margin. New developments have been delivered to the market, as it has been mastered recently, since 2003.

  • CAIMAN supplies all supplied to cultivators with four-stroke gasoline engines Subaru-Robin, Kawasaki;
  • cultivator mills of the Razor Blade type are made of hardened steel;
  • A stamped frame with a handle adjustable in 2 planes;
  • The gearbox is sealed with lifelong lubricant, if necessary, is disassembled, the chain drive;
  • a system of reducing the load on the spine Right Balance;
  • wide network of service centers;
  • Warranty period of 5 years to amateurs, 3 years to professionals.

Correctly note the reviews on the tools of this brand on user forums. There are many Комментарии и мнения владельцев, we list some of them:

  • The instructions were issued common for all gasoline models. It describes in detail the specification, the procedure for repair and security. The procedure for working on equipment missed. Those who see the equipment for the first time have much tormented while they were adopted to work.
  • Caiman cultivators are collected in Kaluga, the informed user claims.
  • Caiman cultivator with a Subaru engine of Japanese production is produced by the series “Subaru E-16 Premium”, engines from China “Subaru EP-16”. See what is on the proposed model. The cost is the same.
  • The layout is uncomfortable, you can get the spark plug only after the hose of gasoline supply hose.
  • Initially, when unpacking, it was found that the clutch cables were wrong.
  • The engine is demanding of the quality of fuel, gasoline from unscrupulous refueling creates a lot of problems, but understanding comes after repeatedly cleaning the fuel and oil drilling system.
disassemble, gearbox

This is not a complete list, there are probably still Комментарии и мнения владельцев, positive reviews are very brief and rare. Caiman cultivators are higher than the average mark.

The horizontal shaft of the Subaru engine fully transfers the load to the working tool. The operation of the mechanism is accompanied by a lower noise, thanks to the engine. The engine is attached to the bed, communication with the gearbox below. belt transmission. Caiman cultivator gearbox transfers torque from the chain leading to the driven star. If the model is equipped with a reverse, reverse, a conical coupling is installed on top. The axis of the driven sprocket goes beyond the gearbox, which allows you to install soil.spaces and wheels. At idle, the Caiman cultivator belt does not pass the torque to the coupling. To do this, you need to squeeze the clutch on the handle, take the tension. In this case, the tension video changes the trajectory of rotation of the belt, and it transfers an effort to the gearbox.

Design features of the mechanism allow the cultivation of virgin and deposit lands. However, the Kaiman cultivator knives are not sharp, so they tear the roots of bushes and perennial weeds, without grinding.

Almost all models have a reverse, which makes the control of units and a reversal accurate. However, the models adapted for processing dense soil and virgin soil cannot be light, and their weight is 46-57 kg. Transportation in a car is difficult.

Hanging guns for equipment will also sell here. With a skillful approach, any work in the garden can take several hours instead of multi.day physical exercises with a chip and a shovel. The plow can be drawn with dumpy plowing dense soil.

The hillock will cut the furrows for planting, in the summer will pin the earth to corn and potatoes. Poloiers will pass through the aisles without harming cultivated plants. Clctions and adapters will help expand the area of ​​equipment use.

It should be noted that the models under consideration can be attributed to the class of professional power and functionality.

CAIMAN 50S cultivator in the ranking of the same tools of this company takes 6th place. The model is installed by the Robin-Subaru EP16 engine, compared to others, the compact device weighs 46 kg, but without reverse. This model is not able to install rear equipment on the coupling. The output capacity is 3.7 liters. With., the volume of the fuel tank is 3.4 liters. The processing width of 60 cm at a depth of 320 mm makes the cultivator suitable if you need to plow the area up to 15 acres. The tool is 23990, at the price of the manufacturer.

Much more functional cultivator Caiman 50s C2. In the rating of models of his company, he took a leading position. Distinguishes it from the previous model the possibility of reverse.

With the same energy indicators, the course back creates significant relief in management. The shaft protruding from the gearbox allow you to use the rear clutch and attach the plow in the kit in the potato worker.

Only one of the presented models of cultivators. Caiman 60S D2, is equipped with a pneumatic drive. The hero easily processes with cutters dense earth with a capture of 90 cm.

To take entirely depth, the unit will require 2 entry. For the first time, he will tear the turf 15 cm deep, plowing a second time by 32 cm.

All hinged guns are hard to the car. Pneumatic drive easily allows you to change nozzles. Weighs the unit 57 kg, costs 33990.

There are more powerful Vario 60S TWK, QUATRO Junior V2 60S TWK, which operate on the same engine, but have another hybrid gearbox. Cars are equipped with 2 speeds forward and reverse. And this allows you to use the front and rear canopies, to treat up to 30 acres of land. Weigh products 72, 75 kg, cost 37, 44 thousand.

Modern agriculture and farming has become much less labor.cost and capacious in time than several decades ago. After all, then the farmer needed to manually or with the help of a fairly primitive technique to perform various types of work: plowing, hilling, cultivation, cut, watering.

Naturally, all these processes took a lot of time and effort, so farming has always been considered one of the most difficult crafts.

Gearbox is collapsible and indifferent. The latest models are installed on motor blocks of the budget type. The details in them are cheap, they are not subject to repair. In case of malfunctions, you need to replace the gearbox. During normal operation, their service life is measured 1-2 seasons. On expensive equipment, the engine is equipped with a collapsible design converter. He serves several seasons properly. With a breakdown of individual parts, the failed part is simply replaced.

A converter of any type may include:

Using the listed parts, movements are transmitted from motor to hinged tools. The chain is put on stars, the belt. on the pulleys. The simplest mechanisms are equipped with belt transmission. They are also considered the weakest and most unreliable. With a large torque, the belts slip and fly off the pulleys. But this design favorably affects the engine shaft. Slippage of belts can be avoided if you change them to gear. With this replacement, you need to change the pulleys.

Varieties

The gearboxes with which the motoblocks are equipped with are the same only at first glance. In fact, these devices can be divided into three groups. Differences are the design features of the gearboxes. Let’s get acquainted with representatives of this family in more detail.

Angular

Angle.type gearboxes are elementary structures that serve to dock the transmission with the power plant power.

Due to the absence of complex nodes, some farmers install homemade options for corner gearboxes on motoblocks.

  • The case of the mechanism.
  • Pip for belt transmission with mounting.
  • Rotor shaft.
  • Flange, coupled with mounting and bearing.
  • Puck and fixing key.

Gear

This is a more complex mechanism, which at home, without special skills and knowledge, is impossible to recreate.

Livestench gearboxes are called lowering. Due to its constructive features, the mechanism reduces the number of engine speeds, simultaneously increasing the output power of the walk.behind tractor.

Such gearboxes have a large working resource, therefore are suitable for various works, and do not receive mechanical damage even with peak loads.

Unlike corner models, lowering gearboxes need additional cooling.

Reversible

This mechanism is based on a clutch that moves freely between conical gears.

Such gearboxes enable the walk.behind tractor to move in reverse, which positively affects the maneuverability of technology.

However, for this you have to pay a drop in performance and maximum speed. Therefore, to install a reverse gearbox or not, each farmer decides on his own.

Gearboxes installed on motoblocks of various manufacturers have practically no design differences. Therefore, disassembling the node and replacing the failed parts will not cause difficulty.

The exception is the budgetary motor units of Chinese. A non.ambitious gearbox is installed here, which in the event of a breakdown is being replaced entirely.

Repair of the motorblock gearbox Favorite with your own hands

Details: Repair of the motorblock gearbox Favorite with your own hands from a real master for Olenord.com.

The presented material in this article is especially in demand for people who repair their equipment on their own. Next will be affected by the main “subtleties” regarding the repair of the motorblock gearbox. To move directly to the topic of repair, you need to understand the device of the gearbox. Looking in advance, it is necessary to say: the structure of the gearboxes of modern motoblocks is similar to each other, there are only minor differences in a particular model.

So that the question does not arise “How to disassemble the motorblock gearbox?”, You need to be familiar with all the details. We list the main details and components of any modern walk.behind tract: covers and pulleys; bushings with bearings; lever, axis and plug for switching; Primary shaft block with gear; The input and output shaft of the motorblock gearbox. Components: washers and seals; right and left semi.axis; clutch and plug; bracket and spring.

Most of the problems in the gearbox of a motor block arise due to overload. Such breakdowns include the sleeve of the bushings on the metal chain, which leads to the so.called “slip”. Also, the owners of the motoblocks very often discover interrupted bushings switching. In order to avoid such troubles, experienced owners advise switching speeds only during a complete stop of equipment, in no case on the go. In addition, a star break is considered to be a common occurrence. That is, factory welding is not enough for the star to withstand overload.

It is very simple to “get out” from this annoying situation, you just need to return the star to its original position and grab it with welding much better. Side loads lead to wear of the support washer, after which there is a fly from the bushings from the chain. In addition to all of the above, it is necessary to periodically check the oil level in the gearbox, as well as to replace it.

Track the amount of oil to monitor constantly. Otherwise, a negligent attitude to technology will lead to fatal consequences. Fresh oil is poured every 50 hours. Along with this, excessive loads should be avoided, which ultimately lead to quick production of mechanisms and components. Let’s move directly to the change of oil:

  • Install equipment on a flat area. Find a probe 70 cm long.
  • The probe bends and is pushed into the opening for the filling of the oil to the stop, after which we take out the rod.
  • Observe the level of oil, which should be at least 25 cm. 2 liters of oil are added to a dry gearbox, a minimum of 1.5 liters.

Pully oil should be Gostovsky. It is pointless to use cheap oil, because sooner or later, it will cause breakdowns inside the motor block gearbox.

Tarpan Reducer Repair with your own hands

Details: Repair of the Tarpan gearbox with your own hands from a real master for Olenord.com.

About idle on a new motor. described his solution to the problem. On the lafan, idle idle speeds are different. the knives rotate.

  • A modernized Tarpan with an old tarpan handle and a direct coupling. Pay attention to the gap between the brake and the handle, without removing the head. the brake cannot be removed or turned over, a very limited range of adjustments.
  • Rolled gender (2nd lies with add.wheels), I rack my head how to straighten out.

They probably have them from plasticine.There are no such signs on my.Although, on my blades with a stiffener. The thickness of the metal looks like yours.

What else do you have?I calmly take mine down, and no problems.Outwardly similar, so.

Would be from plasticine. I would have straightened up. If you read the posts above, here the result of crossing the parts of the early Tarpan (with an ant) ​​with the bought Lifan engine and a gearbox from the new Tarpan. Photos for a deeply respected colleague, shows that it turns out that it will turn out as a result of replacing the oblique trailer on the early tarpan with BS with a direct, without replacing control handles (unless of course they have such (this is 1994 release). On modern Tarpan, the design of the bracket pens is different. there are no problems with pulling out. The details of the early Tarpan are used here. at the other end of the brake. a flat hip, when working on cutters. it is at the top, during transportation. below, like a platform, so that the trunk does not break through. In 1994, Tarpan was regularly equipped with guns for the full cycle of planting potatoes according to Dutch technology (in high beds), hence the brake with a flat cigarette light (if you turn it over), eared cake, a set of milling, gender, limiters, there were no only a dial.

There are discussions about Tarpan on the forumhouse, if anyone is interested in typing this “Cultivator Tarpan (Tula). a full report for a year of ownership with a photo”

disassemble, gearbox

Everything was not enough to read patience. Therefore, forgive it if the question is repeated. First: I plan to stick a rotary plate on the trigger. When turning at 90 degrees, it will be pressed to the handle. Has the right to life? Second: W30 oil is recommended to the motor, which I always forget to buy. Is it possible to use 10W40 oil (including on a trimmer), which is always in the car? And is it possible half.skein instead of mineral water?

Rie. Think for yourself, sa30 is summer, and if you operated MK and in winter. I have a 10W30 with the beginning of operation mineral. According to the instructions, the oil is changed to a heated engine. Just do not tip over the engine towards the filter, the oil can get into it. I usually shoot the filter, for one and cleaning it.

[Quote = Rie; 5232052] everything was not enough to read patience. Therefore, I ask you to forgive if the question is repeated. First: I plan to stick a rotary plate on the trigger. When turning at 90 degrees, it will be pressed to the handle. Has the right to life? Take a closer look at the MB-1 MOTOB block gas control handle, it’s not very expensive, but it’s much more convenient for the full-time invention of Tula masters. I set it myself. I did not regret it, showed itself a very convenient device.

Good afternoon, Tarpanovodov. There is absolutely no time to dig a site and topic, so sorry if such a question has already been covered here. And my problem is in the next. there was noise from the adhesion and gearbox. Removed the power unit. the clutch is normal. I dismantled the gearbox crankcase. the gearbox itself is alive and without signs of wear, I check the oil, I change every season. But the clutch drum is playing. The lower bearing of the worm without a backlash, there is a small backlash in the upper, but the drum dangles seriously and noise specifically if it twirling it with your hand. Apparently, there is also a third bearing under the drum. I could not pull out the worm and remove the clutch drum. I turn to you with this, tell me who had such experience. how to make out this knot ?

Everything is just understanding there.First, the drum is removed, then the lower part of the gearbox body is unscrewed and everything is pulled out.There are no additional fasteners there. On the worm there are two 205 bearing and two on the wheel and all.

If you have saved the operating manual, then everything is drawn in detail there.

Thank you, understand you. Found the same manual on Tarpan. There, in the drawing, the drum is screwed to the worm with a bolt or nut, and I have everything in that place in welding. And in this form and bought it new in the store. Chinese or something ? Apparently, the drum itself needs to be twisted and I do not understand how to do it without a special key or puller ?

I don’t remember exactly, I have been sorting out for a long time, it seems a nut there. How can you twist it now? Except on the weld to gently pose a drill.Similarly, sometimes I analyze the sterful.

Interesting photo of such a miracle.Maybe we’ll offer something else.

Victor K. I could not upload a drum photo here. Only on YouTube. Here is the link “

So I understand that you need to twist the drum itself like a nut. And for this you will have to fix the worm, t.e. collect everything back, otherwise everyone will turn. And then a hammer on a drum through a gap. It seemed that the backlash not only the bearing itself is inside, but also its seat in the gearbox body. There is a new bearing. But how to compact his landing in the gearbox crankcase so that he does not hang out on the outer clip ?

The video is hardly visible (sorinka), but nothing is welded there and the shaft is visible.Most likely a dense landing, and rusted. Carefully look at whether you can see the venerable groove.If the shaft is not screwed and there is a groove, then it will not work.Drip a little WD-40 or brake fluid and let stand for a day.Try to take off. It will not work, then a more radical method, heating the connection (without fanaticism).It is enough to warm up a burner of degrees up to 150-200 (a change in the color of the metal) and immediately try to remove. If there is no puller, then try to knock out the shaft through the copper (other soft metal) entry. Again without fanaticism.
