How to assemble a swivel fist on UAZ. Swivel fist (UAZ). Description and replacement. How to protect against wear

SUV UAZ Patriot in the design of the front suspension is equipped with a swivel fist. This element is present on all vehicles, since without it it is impossible to turn the front wheels. The main purpose of the swivel fist is the possibility of its deviation to a certain angle from the longitudinal axis. Due to this possibility and turns the front wheels to a certain angle. But besides this, the swivel fist is still intended to be able to install the wheel hub with bearings, brake caliper, brake shield and a number of different sensors. Also, this device is a binding element of three systems:

• front suspension;
• steering;
• brake system.

You can familiarize yourself with this element in the UAZ Patriot car. Today we will pay attention to the lubricant of the swivel fist of the UAZ Patriot SUV and that it is necessary to know.

UAZ Patriot is the creation of the Russian car industry, the heart of which is located in the city of Ulyanovsk. Of course, in something, the domestic SUV UAZ Patriot is inferior to foreign, and in something there is no.

One of the problems is that with the factory such a mechanism as a swivel fist is not enough attention. In its design, it is not a little, but there is almost no lubricant at all, which leads to adverse consequences. Already on the first day after the acquisition of a new SUV, motorists may notice the unpleasant sound of metal friction about metal. But, of course, it is not necessary to eliminate such a phenomenon because of the unpleasant sound, but in order to avoid the fast failure of the fist.

By car UAZ Patriot there is two swivel fists who need maintenance from the first day after purchasing an SUV from the salon. If you do not hold a proper lubricant of the product, then with the time its working parts are wear out, they will cover corrosion and immediately fail. To protect yourself from unnecessary waste in the near future and your SUV from the need to replace new details, it is necessary to lubricate a swivel fist in time, which will be enough at least 60-80 thousand km of mileage.

What is used for lubrication

The actual service life depends not only on the presence of lubricant material, but also on the quality of these lubricants. Swivel fist and the Sls are experiencing heavy loads, and therefore heated. Therefore, it should be borne in mind that the material should have not only good anti-wear properties, but also to withstand high temperatures.

Lubrication should also perform a protective function, protecting important structural elements from entering them water, dust and sand. These negative factors when entering a swivel fist lead to its failure. The presence of a lubricant prevents these factors in the design of the device even when the protective anthepses fails.

Thus, to lubricate the swivel fists on the UAZ Patriot SUV, it is necessary to use the Lithol-24 well-known lubricant. One device will require about 400 grams of lithol-24. In the process of carrying out lubricants of the swivel fist, it is necessary to apply lubricant and shrus. For a shrus, you need to use the lubricant SHRUS-4M, which is needed about 100 grams for one side.

Lubrication process

To thoroughly lubricate the swivel fist and the screen, it is necessary to extract these details, clean the internal filling if necessary and apply a new material. For work, you must perform the following actions:

On September 20, 2018, the production of an updated SUV UAZ Patriot began at the Ulyanovsk Automobile Plant. At the assembly of the first car 2019 model year, anyone could observe live.

In the course of the planned modernization, the UAZ Patriot SUV became more powerful, comfortable and convenient in everyday use, not lost off-road qualities.

The main news - instead of the previous engine on the patriot, the Motor ZMZ PRO is installed. The working volume remained at the same level (2693 cm³), but the aggregate has increased the compression ratio and the phases of gas distribution changed. Also note the appearance of the reinforced head of the cylinder block, a two-row chain and new pistons, valves and camshafts.

As a result of improvements, power and torque increased to 150 hp. and 235 NM (it was 135 and 217, respectively). Moreover, the peak of the maximum thrust shifted into the medium revolution zone - at a mark of 2650 rpm instead of 3,900 rpm. Motor ZMZ pro satisfies Euro-5 toxicity standards.

The five-speed manual gearbox also underwent upgrades. Engineers of the Ulyanovsky Automobile Plant improved the selectivity of the drive and reduced the moves of the gear shift lever and the force on it. The lever itself is now composite and equipped with a blank idle damper that improves vibroacoustic comfort. The reduction of noise and vibration background is also due to the installation of a new clutch of the LUK company with a slave disk, an up-to-date idle damper. A 20% decreased force on the clutch pedal due to the new release spring.

After the UAZ update, the patriot should be even noble on the go. In the model of the model 2019, improved steering with a more rigid trapezium and the damper from the UAZ Profi model model. Pros - Increased control accuracy and reduced backlash when turning the steering wheel. From the pro SUV of UAZ Patriot got a front axle with a changed tilt angle of kingle and open swivel fists, thanks to which the reversal radius decreased by 0.8 m.

The improved smoothness of the stroke provide new shock absorbers in front and rear, as well as rear two-liter springs, which are 6% softer former tri-slate. In addition, for the sake of more comfort of passengers of the second row, the thickness of the rear stabilizer of transverse stability is reduced from 21 mm to 18.

The patriot has improved noise insulation of the cabin due to the larger area of \u200b\u200bsoundproofing materials on the engine shield. It has become quieter and thanks to the modernized seals in the openings of the side doors, with which the doors are closed quieter. Plus, exhaust ventilation from the inside of the ceiling in the luggage compartment moved to the zone of the rear bumper.

Patriot has become more convenient for passengers. They are addressed to the handrails on the front and middle bodies, noticeably facilitating the planting process. The fact that UAZ listens to the wishes of customers, says the fact that a double seal appeared in the opening of the fifth door. With him, when opening the door of the trunk, water will not fall into it.

Note that before and during the broadcast, anyone could ask a question. Specialists of UAZ answered the most popular. So, the audience was actively interested when an automatic transmission appears on the patriot. And got the answer.

"Automatic" on the patriot will, we are currently active training. Next year, I assure the automatic transmission will appear, "the Operational Director of UAZ Ruslan Razheva assured.

Required tool:


32x50-10 cuff with spring assembly, 2 pcs.; Inserts (plastic or bronze), 4 pcs.; Gasket Ball support (Cat. No. 31-0121238), 2 pcs.; Schlus-4M; Cold welding;

We establish a new cuff semi-axles in a ball support. The cuff orientation is carried out by the sealing spring - it must be from the gearbox of the main transmission (i.e., when installing the spring, it should "look" at you). Install the gasket on the end of the ball support.

In cases where there is a slight wear or deformation of the pivot support along the inner hemisphere, the use of composite materials is allowed to fill damaged areas. In this case, it is necessary to install a pile and inserts without waiting for the polymerization of the composition.

We establish new inserts (plastic or bronze) in the pivot support on the ball support and we apply to the inner surface of the lubrication lubrication with SCR-4M.

Step 14. Build a swivel fist

Required tool:

Litol-24, 0.5 kg one way; SHRUS-4M, 50-75 grams;

We establish new stubborn pucks of a swivel fist into a ball support and a swivel fist housing.

Before assembling on the inner surfaces of the casing of the swivel fist and the ball support, we apply literal lubrication-24, about 0.5 kg

and insert the semi-axes with a hinge of equal angular velocities, which is applied with a 6m to 100 grams.

Step 15. Installation of ball support

We wear a ball support on the semi-axle, while watching the correctness of its orientation.
The bottom of the ball support is determined very simple: on the flange from the bottom side - three holes, from the top - two. The orientation of the housings of the swivel fists, we recommend notifying when disassembling, for example, core or paint.
We pay attention to it, as the node is collected in any combinations and can be easily mistaken.

Step 16. Square grease

Required tool:

Skvorni; Sls0 4m to 30 grams ";

Conical surface and threads of the clamping sleeve, rubbing the surfaces of the pivot. Lubricate with lubricant SCR-4M.

Step 17. Tightening clamping sleeves

Required tool:


The key of shkvorno; Head at 27; The key is torque up to 30 kgf * m; Soft (copper or aluminum) mandrel; A hammer; Calipers;

We insert into the threaded holes of the housing of the punching fist in the threaded holes and wrap the clamping sleeves before stopping the pivot to the support. If you have installed a pivot with a canal under lubricant, then for further work it is necessary to turn out of them with a keybook key "on 8"

The casing of the swivel fist is resettled with respect to the ball support with an accuracy of 0.2 mm from the ends of the influx of the casing of the swivel fist, with the help of a pivot key with the head "on 27"

1 - pin;
2 - the casing of the fist of the swivel;
3 - Sleeve Scroll;
4 - kkvorn;
5 - insert;
6 - hinge of equal angular velocities;
7 - support ball;
A and b - controlled dimensions, a \u003d b

Alternately increasing torque at 2-3 kgf * m, using moment key (periodically controlling symmetry relative to the ends, the deviation should not exceed 0.2 mm), Tighten the clamping sleeves by the final torque of 20-25 kgf * m.
With a consistent increase in the torque of the clamping sleeve each time through soft mandrel Apply a punch with a hammer (video clugging) along the axis of the pivot on both sides.
It is necessary to ensure the accuracy of the symmetry of the installation of the ball support of 0.2 mm, relative to the ends of the influx of the casing of the swivel fist.
Measurements to produce schuncirkul.
This center is necessary for the correct operation of the seals of the semi-axle and reduce the load on the hinges of equal angular velocities.

We draw your attention - after tightening the clamping sleeves with an effort of 25 kgf * M ball support relative to the casing of the swivel fist rotates very tight, so it should be. The force of rotation is adjusted separately - by tightening the gallowing nuts ().

Step 18. Flooding of the clip and cuffs of the swivel fist

Required tool:

Lithol-24, 100 grams; Head at 10.

The cavity between the ballproof and the casing of the swivel fist is picked up Litol-24.

Then we install the swivel fist cuff ..

Install the felt ring (ring SP134-12-5), which must be pre-impregnated with machine oil.

Install the cuffs of the swivel fist

With the head "on 10" brought it to eight M6x12 bolts

Step 19. Adjustment of the lock bolt stop

Required tool:

Key 12, 14, 17; Calcircular with a depth hencer (Colombian);

We screw the locking bolt-stop with a locknut, set the measured previously measured altitude and fix the key "on 17" and the key "to 12".

Turn the M10x1x16 bolt "by 14".

Step 20. Installation of gasket and lever of the swivel fist

Required tool:


Head at 19; Gasket under the lining of the pivot (cat. №3160-2304028), 3 pcs.; Gasket under the swivel lever (cat. No. 3160-2304029), 1 pc.

We install the gasket, the lining and retard the M16x1.5 nut with the flange on the kingle.

We establish the gasket and lever of the swivel fist, the slot sleeves and screw them into four ML2X1.25 nuts with the head "on 19" and screw the M16x1.5 nut to the flange. This photo features a swivel fist lever for UAZ-374195 cars and its modifications

Step 21. Installing a swivel fist with a semi-axle

Required tool:

Key by 14.

We bring a swivel fist with a semi-axle to the fan of the semi-axis on five special ML0X1X30 bolts, two of them were pre-dress limited turning, the key "at 14" until it stops.

Attention, after a run of 200-500 kilometers. Repeat the tightening of the specified five special ML0X1x30 bolts.

Step 22. Adjusting the ball support

Required tool:


Head at 24.

This is the machine node

A knot that enters the turning fist of the OAZ of the front bridge is a ball kin. He assumes all the load, which falls on the front axle during the movement. These loads are especially great when driving off road and rough terrain.

During the operation of the car, this squava node is quickly flashes, which leads to the appearance of gaps and backlash in the front suspension.

Repair of the swivel fist is necessary in the following cases.

1. Replacing the liner or seal node.
2. Wear a ball pivot.
3. The swivel fist was deformed and requires replacing the ball support.

Often, the breakdown of the swivel fist is caused by the poor-quality selection of components installed during its assembly, namely inconsistency:

• diameter of support and inserted hemisphere;
• the thickness and planting place of the gland;
• thickness of liners.

Features of prevention and repair

Repair of the UAZ swivel fist can be carried out both independently and contacting the car repair shop. The cost of repair work will depend primarily on the price of details to be replaced.

Fist dries

If there is some experience and the necessary toolkit, having studied the instructions, how to disassemble and repair the swivel fist, it is enough to buy the required snacks and independently carry out all the repair activities. This will allow not only to save money, but also to get new knowledge about the design of the car.

We must not forget about regular preventive measures consisting in inspection and assessing the state of the clamping sleeves of the swivel fist, as well as identifying the presence of a backlash in the front suspension.

Before starting the repair of the swivel fist, you need to familiarize yourself with the features of it.

1. If nyloc nuts are installed, they will definitely be replaced, as they have a special coating that prevents them from unscrewing and loosening the clamp. After screwing nuts, this coating is destroyed.
2. You can not put a car on the wheels, if at least one drive shaft is disconnected from the hub, as this can lead to deformation or damage to the hub bearing. If you need to move the machine to a slight distance, the shaft must be returned to the hub and fixed with a nut.
3. Depending on the car model and the year of its release, the OAZ fist has two modifications, in one of which the hubs are solid, and in the other - hollow, which is determined by the presence of the opening.

Before starting repair, the following manipulations are carried out.

1. The car is put on the hand-made brake.
2. Under the rear wheels are put up, which will prevent the movement of the machine.
3. The front of the car rises by a jack or winch and fixed on the stops.

Only convincing the reliability of fastening the front of the machine and the impossibility of moving it or disrupting the stops, you can start removing the wheel.

The process of dismantling the wheels and brakes

To remove the wheel, you need to perform operations in such a sequence.

1. The wheel hubs remove the cap, remove the R-shaped bracket, dismantle the lock head. On the drive shaft weakened the nut, which connects it with the hub. After that, I remove the front wheel.
2. If the car model is equipped with the ABS system, the sensor is on the wheel, which must be dismantled.
3. The screw fastening of the drive shaft to the front suspension hub is twisted.
4. The brake caliper is attached to the twist fist with two bolts that need to unscrew and disconnect the caliper from the brake disc, after which it is tied up to the spring on the front suspension.
5. Before proceeding with the removal of the brake disc, it is necessary to mark its location relative to the hub of the suspension. The trait can be applied with chalk, but it is better to use white paint, so that during the fulfillment of repair work it was not lost. Only after that turn the fastening screw and remove the brake disc.

Lubricate fist.

To facilitate the dismantling process from the rack of the swivel fist, it is necessary to use a special device, with which the pendant springs are compressed and fixed. For this, cables are used, for example, as on the device 0903 AF. The compression and fixation procedure springs in the following way:

• at the top of the rack there are two holes, in one of which the cable is inserted;
• the steering column is then rotated and the second cable is inserted into the second hole;
• the free ends of the cables cling to the bottom edge of the cup;
• the upper ends inserted into the rack are fixed by screwing into the bolts in the bolt hole with a diameter of 6 mm.

The swivel fist is designed to change the direction of the car by enhancing the pressure on the steering levers, which ensures the change in the angle of the wheels.

This part of the vehicle is one of the most significant. Swivel fist (UAZ, Volkswagen, BMW - no matter) is the basis for the hub and attached to other details due to usually allocate two types of parts: with a hub and with a spindle.

Approximate cost in the market

There may still be a swivel fist left or right. Externally, they are practically identical, but since these parts are directly related to the best of all will be reinsured. On one of them there is a sushka on another exit to the longitudinal traction. It is for these reasons that their cost differs.

Autodetas can be purchased in auto shops, on car markets, order on various sites. The right swivel fist costs about 8,400 rubles, on the left price begins from 6530 rubles. These are approximate rates of fists on the UAZ-31519.

Do not save, even if the cost of domestic spare parts will be higher than Chinese. More than probably, expensive item will last much longer.

How to make the right choice?

When buying on the market, you should pay attention to the saddle, where the bearing of the swivel fist is installed (the inner clip must be closed close without the help of the hammer), as well as the appearance of the detail: whether there are corrosion, there are cracks or reinforcement. Any crack subsequently can turn into a problem very difficult to solve.

Design details

The parts of the swivel fist include the hub and the brake disc. In addition to the most important part, they enter the main set of spare parts intended for the steering.

But the most important thing in this list is still a swivel fist. UAZ will serve as a car, on the example of which will be built a scheme for removing the fist.

Replacement and repair

Despite the seeming complexity, the replacement of such a detail, as a swivel fist, does not represent much difficulty. First of all, you should put the vehicle to the handbrake, then under the rear wheels substitute the anti-parameters and raise the front part of the car by the jack.

1. Remove brake disc.
2. Remove the attachment of the trough.
3. Remove it assembly with the clutch of the shutdown of the wheel, the brake disc shield and the hub.
4. Remove semi-axes.
5. Separate thrust from the swivel fist.
6. Remove the bolts that are fastening the ball support to the fan of the casing of the semi-axis.
7. Remove the stop of the wheel limiter.
8. Following the installation, discress the shank of the ball support from the casing of the semi-axis. For this use puller for ball hinges.
9. Carefully remove the desired detail, in our case the fist swivel.

Action Fist Replacement Ambassador should be performed in the reverse order, without forgetting to put the rotation limiter. For repair, the swivel fist should be prying in vice and disassemble it by twisting the cuff mounting bolts, a bolt limiter with a lock nut. Next, the cuff clip is removed and the felt seal. At the end of the ballproof gland is extracted.

The most difficult behind, remains that requires attention. A ball support is neatly retrieved. Approximately this is the repair and replacement of the swivel fist.

Replacement of shkworn

There are more details that you need to be replaced from time to time - this is a shine. To replace them, you will have to remove the swivel fist and clamp it in the vice. After that, with the help of a mandrel, you should knock out the sleeve of a kkworn and well clean the passes under lubrication and under the replacement spare part in the fist.

After the rim, you set new sleeves in such a way that the holes in them coincide with the holes on the fist, and the open ends looked in the direction of the beam fixed on the front axle.

At the same time, both sleeves are deployed to the necessary diameter. After that, clean the sleeve and cause a thin lubricant layer. Then, lubricating sealing rings and ducts in the bunch of fist, install the rings themselves.

Possible damage

Despite the fact that the swivel fist is one of the most "long-playing" details of the car, its damage is just a matter of time. Sometimes a protective casing can be cracked, giving access to dust and sand inside, so it periodically controls its integrity.

In the event that it fails, the best way out will be replaced. Often it can be seen on a swivel fist of oil drums, testifying that the joke of the gland / semi-axle is a loose. Here you should simply change the gland at better. Such problems are often found in cars that have fallen into an accident.

How to protect against wear

Those car owners who recently bought a UAZ, often when rotating the steering wheel hear unpleasant sounds, as if the metal was hitting the metal completely without lubrication. Often it happens. How can the fists on the domestic car be protected? Here the omnipresent Litol comes to the rescue.

If there is no experience in repairing cars, then you can the left swivel fist, like the right, to deceive only outside. For more familiar people in the car mechanic, such a way is suitable: by reloading a circular gland, move it to the center of the car and add more lithol to the resulting slot.

These operations are made after cleaning the car from transportation paint or polyethylene. You should also check the presence of a seal.

Construction of the swivel fist

The widespread design of the swivel fist is the so-called "straight cross." Although most of them look almost the same, but there are differences in size. One can be a little more, the other is a little less.

The fist swivel is usually made of steel. Thanks to this material, such an important item is capable of withstanding colossal loads. But with all this, the more easier there will be a piece of fist, the better there will be depreciation and handling. Therefore, designers are trying to obtain the optimal weight ratio for strength.

Planting places on auto parts are specially designed for fastening the dirt protection rings that do not allow to penetrate the hub bearing with all sorts of garbage. The housing is designed in such a way that it was convenient to screw the suspension elements.

You can ask why most of the article is dedicated to the UAZ car? The answer is: because it is a domestic car that has managed to prove well - easy to maintain, reliable on the road.

Many underestimate this car, believing that foreign cars are better, but it is not so. In many ways, the UAZ, even released in the Soviet Union, exceeds many modern SUVs, but, unfortunately, it remains unrecognized.

Although made of steel, a swivel fist is one of the weak places of any car, often because of bad roads. It is worth watching him, because in a responsible minute it is this part of the steering that can help avoid accidents.
