Hello everyone! Tell me who knows, the blocking stopped turning on. When there was a new car, it was difficult to turn on and off, but it was possible. Now I can’t turn it on, not how. Maybe a competent service will tell you in Moscow?
As they teach in the book, rolling forward and backward, it did not stop working, it just rusted, I have the same garbage with great difficulty, because I rarely use it

Thank you for your answer. I don't use it often either, but at every opportunity I try to lubricate everything. The whole thing turned out to be in the activation rod. The old one has a lot of work. Now it turns on easily without straining.

I bought a new gazelle for Dekaborsk 33027. and I don’t understand the dollar. since when the differential is turned on, the orange one lights up. And is the 4x4 gearbox modernized or of the 1997 model?
No, it should not, since there is NO such light bulb. Its own checkpoint. Differences: there is no hole for the speedometer drive (on the RC) and there is a hatch instead of which you can put a COM.
ЗЫ Specify your location, please.

There is no reason for her to light up and there is no place for a light bulb, unless you start a reserve. The differential lock is lit so that you do not drive and fly away on the asphalt with it. and the reduced one does not affect this. The gearbox is the same, only holes are drilled for fastening the differential and lowered levers and on the other side of the COM fastening hatches it is milled and closed with a metal plate. the number of gears is unfortunately the same, in bridges 5.125

my transmissions are stuck with difficulty and constantly when driving there are two different sounds from under the checkpoint. So it should be for a car with a mileage of 300 km ??
About sounds in more detail, and "transmission with difficulty" - imported clutch (see sotv. Topics) and oil in the gearbox synthetics.

appear when moving from 20 km. The first cricket (rattles) trtr-trtrtrtrtrt. the second buzz as if the wheels are out of balance, vibration is felt.
The first is most likely from the levers of the PKK. And the second is the propeller shafts (I talked with the balancing expert - it is imperative to balance, since they do not do this at the factory), although you need to start with balancing the wheels.
appear when moving from 20 km. The first cricket (rattles) trtr-trtrtrtrtrt. the second buzz as if the wheels are out of balance, vibration is felt.
The first cricket is most likely the washers at the ends of the lowered and blocking levers and, respectively, at the ends of the rods from the side of the pk. It is easy to check if you put less noise on these levers while driving. From the side of the pk on a thrust for 35 tkm, the development formed 0.5 mm until I found it. It was cured very simply put rubber washers from a piece of hose, instead of native plastic ones. it is better to change everything at once. Native rubber K-139 at a speed of more than 90 km makes a louder noise than the engine, with such a characteristic hum due to the tread

Today I have already successfully tested the electric drive for controlling the transfer case. For this, two motorized windscreen wipers from a Muscovite were used. They are to the frame, and the movable levers on them cut straight into the rods.
That's it, now a 4-hour trip to the dacha will not drill my brain with the ringing that drowns out the radio tape recorder. Only two extra buttons on the panel https://my.housecope.com/wp-content/uploads/ext/3317/forum/public/s. )))))))
Somewhere I saw a photo, they installed electric engines from ESP. It worked too. Photo and description of the process in the studio!

A 4x4 transfer case for a gazelle is a unit that distributes torque from the engine to other drive mechanisms that also increase the number of gears in the transmission.
Transfer case 4x4 for gazelle
A transfer case is a unit that distributes torque from the engine to other drive mechanisms that also increase the number of gears in the transmission.
The device is an integral part of all-wheel drive vehicles. The first transport analogs appeared only at the beginning of the last century. They were intended only for racing on the highway and off-road, and they looked like a passenger car. The public at that time considered the development to be simple pampering. After a number of manipulations, a transfer case was produced that fulfills the tasks of modern analogues.
Based on the method of distributing power between the bridges, the 4x4 transfer case for the gazelle of our time is diverse:
- With an interaxle differential drive, which does not provide for the possibility of forced shutdown of one of the driving axles. Cars with such a box are characterized by the constant operation of the front axle. If it is necessary to increase the passage, the center differentials switch to forced locking.
- With an interaxle differential drive, which provides for the possibility of forced shutdown of the front driving axle. Due to the use of a single main gear, this type has gained such popularity.
- With an inter-axle drive of a blocking type with a manually disengaged second drive axle or with the help of an automatic system when the wheels slip. Cars with such a box when driving on a hard surface provide for the disengagement of the front axle. This condition helps to save fuel and reduce tire wear.
- With non-axial driven shafts. An intermediate shaft is not provided here. Main advantages: compactness, noiselessness, high efficiency.
The 4x4 transfer case is responsible for the distribution of forces on all driving axles of the vehicle. Its additional use is starting and stopping the driving front axle. Basically, a gazelle of this type is characterized by a two-stage gearbox. Its work affects the gear ratio, as a result, the number of gears is doubled.
When starting a direct transmission to a 4x4 gazelle, the first row of gear ratios is introduced, and when lowering, the second. This factor causes the vehicle to travel in a variety of road conditions.
The high cross-country gazelle is characterized by a design that blocks the possibility of engaging a downshift provided the front axle is on. A device of this type makes the rear axle insensitive to high torque overloads.
Transfer case device 4x4 for Gazelle
A 4x4 transfer case for a gazelle is characterized by the following main components:
- drive shaft;
- rear axle drive shaft;
- front axle drive shaft;
- center differential;
- a device that blocks the center differential;
- gear or chain transmission;
- reduction gear.
The torque, as the main acting force, is transferred from the transfer case from the gearbox through the drive shaft. The center differential is responsible for the distribution of torque between the axles. In turn, it causes rotation at speeds with different angular values.
The variety of the center differential for a 4x4 gazelle includes two types:
- symmetrical, characterizing the uniform distribution of torque;
- asymmetrical, characterizing a different ratio of torque distribution.
In order to rigidly hitch the front and rear axles, a differential lock was provided for a 4x4 gazelle.
The task of the chain drive is to transmit torque to the front axle, which includes gears and drive chains.... It happens that the gear drive is replaced by a chain drive. And the all-wheel drive system with an automatically connected type of transfer case has the form of a bevel gearbox.
The crawler gear is assigned the role of increasing torque when driving off-road vehicles. The design of the planetary gear is borrowed here.
Driving on deformable soils usually does not imply the circulation of parasitic power, since the value of the total component of the movement resistance force is decent, and the adhesion of the wheels to the supporting surface is insignificant.
A 4x4 transfer case for a gazelle is characterized by regime operation:
Further modes are differential-oriented.
- Its unlocking with the condition of the included overdrive. The division of the torque is in the form of a 1: 2 ratio.
- Blocking with the condition of the included overdrive. The torque split depends on the grip and the surface.
- Unlocking with the condition of a downshift engaged. The torque distribution is represented by a 1: 2 ratio.
- Locking with the condition of the included underdrive. The distribution of torque is carried out depending on the adhesion of the tires to the surface. The functioning of the front and rear axles is inseparable. This mode has the highest passability.

The Avtohis company sells original components for GAZ vehicles, manufactured at the factory and passed multi-level quality control during the production process. The reliability of such parts is much higher than that of numerous handicraft counterparts presented on the car market.
However, the price of a branded handout for «Sable» slightly different from the products of Chinese masters. However, it is advisable to purchase a factory-made unit. The absence of problems when working in any road conditions and a long period of operation will more than pay off the additional costs in the first months after purchase.
The transfer case is one of the most reliable car parts. A complete replacement of the transfer case is usually carried out in the event of:
- critical wear of most of the elements of the assembly;
- shock contact with the coating or damage from an accident.
In other situations, it is enough to replace individual failed components. The distribution box promptly signals the appearance of problems: there is extraneous noise during the operation of the unit and there are difficulties when switching modes.
The Avtohis online store provides its customers with the opportunity to purchase original spare parts for domestically produced cars on favorable terms. Thanks to the direct supply channel directly from the manufacturers, we offer to buy a distributor for Gas "Sobol" at the factory price. An individual approach and meeting the needs of each client is the main principle of our company.
The transfer case is an integral part of any 4WD vehicle. It is this device that is responsible for the distribution of the engine torque between the driving wheel axles of the machine.
Modern hand-outs provide for the possibility of engaging all-wheel drive or only one of the axles. The system of center differentials, similar to the design of the rear axle gearbox, allows the vehicle wheels to move at different speeds, and the possibility of forced blocking of this device allows you to overcome difficult-to-pass road sections without problems.
The distribution box for the all-wheel drive GAZ "Sobol" 4x4 has the functionality traditional for the cars of the Gorky plant:
- three-position control lever: engaging four-wheel drive, activating only the rear axle and neutral (both axles are off);
- modes of low and high gears;
- center differential with the possibility of manual blocking.
All elements of the transfer case are housed in a metal crankcase with a sealed cover. The maintenance of the unit is reduced to checking and changing the oil. The box signals the occurrence of problems in advance: there is extraneous noise during the operation of the unit or difficulties arise when switching operating modes.
The Avtohis company offers its customers original spare parts and components for GAZ vehicles. Here you can buy a razdatka for Gazelle 4x4, made specifically for aggregation with power plants of the Zavolzhsky Motor Plant. All products offered for sale are assembled from quality parts in compliance with the assembly process and passed mandatory testing in the form of finished products.

After the article about the gearbox of the combat "Sobol" of the GAZ Raid Sport racing team, many questions arose about the razdatka working on this car in tandem with the checkpoint. Once there are questions, there will be answers.The technical director of the team, Ivan Sedov, exclusively for the readers of EX-ROADmedia, reveals another batch of secrets about the construction of the Sobol 4x4 racing car.
According to the reviews, the public wanted to learn more about the transfer case (hereinafter - RK), which we use on our "cars", and so the information has been collected, in principle, a long time ago, but why was I in no hurry to publish it? Yes, because I was in no hurry ... There was simply no desire, since the information is rather ordinary and talk about how cool the Koreans came up with a good RK and successfully sold it to one of the car factories in Russia, which was lazy, or maybe simply could not develop its own razdatku, not that I don’t want to, but even somehow ashamed ...
Well, we took the path of least resistance and solutions - we simply adopted the RK of the same manufacturer as the gearbox we are using so far - Dymos, which does not pull the standard RK of the all-wheel drive Sobol - it just does not pull it out and breaks down. So for now we are riding the stock RC Dymos.
A little about the characteristics of the RK:
- Four-wheel drive - Part-Time - permanent rear, connected front.
- The front axle flange drive (type of torque transmission) is a chain drive (which makes it possible to partially compensate for the difference in the speed of the front axle, relative to the rear - relevant for our operating conditions).
- Control of the actuator - electronic servo - worm - fork - clutch with synchronizer. Synchronizers allow you to pretty painlessly include front-wheel drive at almost any speed, if necessary.
Even in the stock version, there is a downshift with a reduction ratio of 2.542, but we have it electronically disabled, since it is prohibited by the regulations.
Whoever has a desire to read in more detail about such an RK, then on the Internet there is quite a good instruction and feedback on operation in stock
In competitions, even in a marathon, we cover no more than 10,000 km. As part of the Russian Championship, it is generally in the area of 1000 km. Therefore, the transfer case, we must give it its due, withstands careful operation. Although after each race, like all nodes, it undergoes a rebuild. I cannot talk about the same problems that, according to reviews, the owners of the cars from which the Republic of Kazakhstan was taken, the incidents have not yet been registered.
The nuance of the installation in our case is that serial units are logically arranged in Sobol. The front axle drive is on the left in the direction of travel, the exhaust pipe, so as not to fry the driver and his legs, is on the right. But in the basic version of the car from which we borrowed the unit, the situation is different - the front axle drive is on the right in the direction of travel.
Our team periodically encounters difficulties with electronics and other endeavors, rally-raid is still a tough sport, but we work with hardware just once or twice. Sawing off, welding, and even more so "fixing" is not a question! To implement the roll-over-reversal of the RK in practice, a transition flange was designed, which, in fact, is a sheet of iron with attachment points to the checkpoint and exactly the same points, only in the direction of the RK attachment turned in the direction we need. The angle of rotation of the RK for cars of class R and T1 is different for us - a feature of the unit layout.
In the process of turning the RK in the right direction for us, we assumed that the Koreans would probably come up with a unique lubrication system for mechanisms, and not just “shovels” that randomly spray oil. So it is: inside there is a full-fledged pump with an intake, which takes oil from the lower part of the RK crankcase and presses inside the shaft, lubricating the gears and couplings from the inside (by analogy with lubricating the engine crankshaft).
I had to take the GAZ-24 fuel intake with a filter attachment, which cuts off large mechanical fractions that appear during operation. And why the fuel intake - so it just came up on the inner diameter.
The design turned out to be successful and without flaws: the filter works as needed, and has approximately the same cell size as the standard RC, the metal tube is rigidly fixed among the mechanisms and the chain, which eliminates accidental unwanted contact, the flexible hose makes painless joint between the tube and the pump, which moves slightly on the shaft during operation.
The standard crankcase ventilation system was simply drowned so that oil would not leak through the "breather", because now we have the top - this is the bottom, and the bottom is the top.
But just in the new "ceiling" a new "breather" was installed.
Actually, that's the whole secret of the hand-out coup-reversal relative to the checkpoint. I would like to pay special attention to the surface inside the crankcase, as well as to the adapter flange. Inside - perfect cleanliness, in the photo of the Republic of Kazakhstan - the well-worn, passed the "Silk Road". The silhouette of the crankcase cavity of the RK is clearly visible on the flange - iron oxides are corroded, pure metal remains - many thanks to our sponsors for providing high-quality lubricants! The work is obvious, and in our case - on the flange.
Towards the end, I remembered one more nuance, why I had no desire to write about RK - this information is just for information and is absolutely useless for use. You can't put such an RK on a serial Sobol - it won't fit geometrically, the front universal joint is 15 cm long - of course, it's absurd ...
In the next article, if everything goes well, then we will talk about ...
