The UAZ-3741 car ("loaf" or "Tablet") is not demanding road covering - He will drive there, where it is necessary, and not where it is possible. In many ways, this is the merit of the front leading bridge, which always comes to the rescue - read this article in this article about this node, its types, devices and rules of operation.
Device of the chassis and transmission of UAZ-3741
Already the first car of the Ulyanovsk Automobile Plant - the famous GAZ-69 - had a wheel formula 4 × 4, possessed simply fantastic patency and was extremely unpretentious. And until today, the concept of "People's SUV", laid in the legendary "goat", remains relevant and implemented in all modern UAZ models. The four-wheel drive is also provided in the UAZ-3741 car (until 1985 - UAZ-452), which is more famous called "Buanka" (which reflects its characteristic form) or "Tablet" (as a result of frequent use as a "ambulance" and sanitary cars in the army).
The basis of the undercarriage of the UAZ-3741 is two leading bridges having a classical dependent suspension on semi-elliptic springs and hydraulic shock absorbers. And only in this model, the springs have 13 sheets (in the other sheets of sheets less), and on the front and rear suspension springs are interchangeable.
The car transmission has a pretty simple device, it is also built according to the traditional scheme without any features. Transmission contains a 4-speed gearbox with manual control (classical manual transmission), which works in a pair with a two-stage dispensing box (has an increase and downward transmission) - due to the presence of "disduction" possible gears Increases twice as many times increases the possibilities of transmission. Torque OT dispensing box With the help of two cardan shafts Transmitted to the front and rear leading bridges. In the leading bridges, the moment is divided into two streams and is sent to the wheels, ensuring their rotation.
Separately, let's talk about the appointment and device of the front leading bridge of the car of the UAZ-3741 family.
Front and rear suspension of the family of cargo-passenger cars UAZ-3741, UAZ-3962, UAZ-3909, UAZ-2206, UAZ-3303 wagon layout - spring, two types, consists of four longitudinal semi-elliptic springs working together with telescopic double-sided shock absorbers.
Front and rear suspension of cargo-passenger cars UAZ-374195, 390945, 390995, 330395, 330365.
UAZ-374195 - van with a all-metal closed car body, divided into a double cab and cargo compartment. UAZ-390945 - cargo, with an increased base, five-seater cab and metal platform. UAZ-390995 - van divided into double cabin, five-seater passenger compartment and cargo compartment. UAZ-330395 - cargo, with double cabin and wooden platform. UAZ-330365 - cargo, with an enlarged base, double cab, metal or wooden platform.
Stamped springs increase the area of \u200b\u200btouch the sheet with a rubber pillow and reduce its wear. Rubber pillow has a greater top and bottom thickening connected by a jumper. With the help of these pillows, the ends of the springs are embedded in cast brackets made of ductile cast iron glued to spars frame.
Covers are attached to the spring brackets from the bottom. The tightening of the covers is created by the necessary root of rubber pillows located between the bracket and the lid. Removable covers make it possible to dismantle the springs and replace rubber pillows. Fastening the ends in rubber pillows provides noiselessness in the work and does not require lubrication.
To the bottom of the frame of the frame, the bolts are mounted cast iron clipboard. Located inside this clip rubber buffer softens the blows perceived by spars with small springs. Spring deflection when the bridge is up, limited by the rubber buffer, in it, with a fully compressed buffer, a bridge housing is resting.
When installing springs on the car, there is no need to distinguish the front end of the spring from the rear, as stamped cups, glued to indigenous sheets, are the same. Catalogue number Spring - 452-2902012-03 or 452-2902012-04.

The SUVs of the production of UAZ have decreed considerable popularity on the expanses of immense Russia, but many UAZ has one large disadvantage - low level of comfort.
- 1 Tuning UAZ "Buanka" do it yourself
- 2 Tuning Salon UAZ "Buanka"
- 3 external tuning "loaf"
- 4 Tuning Suspension UAZ Buanka
- 5 Tuning Engine UAZ Buanka
Also not too easy to use cars of the UAZ series 452/3303, so many car owners try to upgrade the car by making various improvements into it. Tuning UAZ "Buanka" - the topic is relevant, interesting to many motorists.
Tuning UAZ "Buanka" do it yourself
Cars increased passibility UAZ-452 is distinguished by remarkable technical characteristics, and the car on off-road qualities practically does not know equal. UAZ "Buanka" is one of those few cars that do not rush to donate in scrap metal, very often these cars restore, tuning make. Moreover, almost any nodes and parts are subjected to modernization, ranging from the cabin and body, ending with a power unit, bridges and suspension.
Unfortunately, the Ulyanovsk plant was not too taking care of the comfort of the driver and passengers of the SUV, and often bring to mind UAZ to the owners of cars themselves. Another lack of "loaf" is instability on the road at a speed of over 90 kilometers per hour, but also the car owners are not lost, modernize the suspension, change the caster (the angle of the wheels).
What can be done with loaf do it yourself:
- produce an elevator front and rear suspension;
- install the machine more powerful and tracked motor;
- equip the SUV with additional light;
- change civil bridges on the military;
- repaint the body in Metallic, or apply airbrushing;
- todded side I. rear glasses;
- change the front and rear bumper;
- dock filled car winch;
- install body kit - kangaring, roof trunk, staircase on rear door;
- change the wheels to the biggest, with the best tread;
- insert the preheater in the car.
In general, you can still do a lot, the main thing is that for tuning UAZ "loaf" with their own hands enough fantasy, skills and money.
Tuning salon UAZ "Buanka"
Sitting in UAZ on the "native" seats is extremely uncomfortable, and when it comes to tuning salon UAZ "Buanka", first of all car owners change the seats in the car. To refine the "sids" there is a lot no sense, it is easier to "introduce" chairs from some foreign cars or Russian a passenger car.
But there is one problem - there is a very few place on the front passenger and driver's seat, and not all the "foreign" chairs will fit here. If we consider "sids" from the Russian cars, then the seats from the "Oka", "nine", "forty-first Moskvich" will enter the interior. True, high quality spare parts with Russian cars are not different, so it is better to take a chair from foreign cars:
- Mitsubishi Delica;
- Honda Civic.;
- Toyota RAV4;
- Opel Astra;
- Volkswagen Passat. B3.
Seats should not be wide, otherwise they are not placed in the cabin. But this is not the most important thing - it is important that they are not high, then it will be impossible to sit behind the wheel. 
If the car goes on a long trip, for example, fishing or hunting, it is important to organize comfortable sleeping places. The tuning of the fishing salon also provides for the installation of a table, followed by a dine during a trip. Of course, it's not bad to arrange a picnic and on the shore, but the weather is not always good, and I will not sit in the rain on the street. 
No less important in the rear passenger compartment to carry out normal lighting - again the "native" light leaves much to be desired. But here it should be borne in mind that a large number of salon plafones "eats" a lot of electricity, so even enough good battery You can easily plant. The exit of their position is, it is necessary to put LED lights instead of ordinary light bulbs, and they have a lot of advantages:
- spending some electricity;
- lED bulbs look aesthetic;
- light the LEDs brighter;
- such lamps are much more durable.
There is a disadvantage - LEDs are noticeably more expensive, but setting such lighting once, for a long time you can forget about the replacement of light bulbs. 
Another disadvantage of UAZ is a row standard steering wheel, and he does not like many drivers. You can try to replace the steering wheel on something better, but there is one problem - the steering wheel is not easy to pick up on the slots. Many car owners put the steering wheel from Gazelle, but without alteration it turns out too high. Specially adapted steers for the UAZ are sold in auto shops, they are easier to change them. Another option is to install the steering wheel assembled with the steering column, then everything is just suitable for fasteners. If there is no desire and opportunities to mess around with the alteration of the steering wheel, you can push the braid on the rim, it will also suit the Gazelle.
UAZ UAZ instrument panel looks quite primitive, and in order to somehow improve it, some masters of the machines are covered with a "tidy" film. You can still put dashboard From GAZ 3110 or "Gazelle", but here the alterations will already be more. 
External tuning "Buanka"
UAZ 3303 - Very durable and reliable carNevertheless, the body and body elements are subject to corrosion. First of all, you begin to rot the doors, body frame, floor. If the body went rust, repair is required, and no welding here can not do. After work, the body of a loaf is treated with a lead turret with a oliff, also exist special means For the processing of body iron.
After welding and straightening work, the body painting is required, but paint the car into the standard green color not interested. Tuning UAZ differently, and on the roads you can often see "loaf" tuning:
A considerable role in tuning played kit, and it is needed not only for beauty:
- kangaring and power bumpers protect the body from shocks;
- the roof trunk allows you to unload the car's salon, take more cargo with you.
Elements of the body of external tuning for UAZ can be bought in auto shops, the most popular is reef products. On force front bumper factory production can be fixed mechanical or electric winchwhich is simply necessary in off-road conditions. 
Also, not for beauty serves the trunk on the roof, but still I want it to look aesthetic. To make pretty homemade trunk, It is necessary to have laid skills and experience, and without a certain skill, it is still better to buy finished products in auto shops. From factory expedition baggage The brackets are provided for the installation of additional light, the factory product can withstand the load up to 200-300 kg. In addition to its main task, cargo the trunk also performs additional features:
- protects the roof from all sorts of damage;
- serves to accommodate additional light lamps;
- may be transported, for this, a special fastening is provided for the trunk.
Considerable importance on UAZ has additional light, move in the dark without good powerful headlights is quite problematic. Additional light is installed not only on the roof, but also ahead, on force bumper (Kangaring). It is best to install LED headlights, they have several advantages:
- lED lamps serve for a very long time, the life of the lamps - from 25 to 50 thousand hours;
- lighting is obtained bright, close to natural light;
- lEDs consume very little energy, approximately 10-15 times less than halogen lamps.
But the LEDs also have their drawbacks - while still lighting devices of this type are quite expensive, and if the LEDs burn out, it is necessary to change the entire headlight. 
Tuning Pendants UAZ Buanka
Some motorists ask a question - why do you need tuning for off-road, if UAZ and so has very good permeability? Of course, the "loaf" is well adapted to the rough terrain, however, in the impassive dirt it can get bogged down. To make it easier to overcome the roads, the suspension of the car UAZ 452/3303 / 3962 and other modifications subjected to lifting - with the help of special spacers for the springs increases ground clearance.
It should be noted that to increase the clearance you can realize not only the lift of the suspension, but also from the body itself. In order to raise the body relative to the road, additional spacers are laid between the chassis and the frame. The frame to the body is attached to ten bolts with nuts, but the fastener is sometimes not easy, since the nuts with bolts are covered with rust with time, and it sometimes happens quite problematic.
You can carry out the suspension lift using additional springs, as well as the installation of spacers between bridges and springs (still set extended spring earrings). Special sets for lifting are sold in the auto shops, and increase the ground clearance can be at different heights - 20, 30, 40 and 50 millimeters. But it is intended to raise high body relative to the road, it is necessary to take into account that in this case the car loses its stability, and the risk of tipping. 
Tuning Engine UAZ Buanka
Old UAZ-452 models were completed with the engine of Ulyanovsky Motor Plant Umz-451, as well as other modifications of the DVS Production UMP (414/417 / 4178). In the future, the Waws of the Volzhsky Motor Plant appeared on the UAZ, such as ZMZ-402 (4021) and ZMZ-409. Ulyanovsk motors of the first editions are unlikely to make sense to modernize, in the case of the release of the engine, it is easier to replace it. But the Motors of the ZMZ tunify, and not so rarely.
What you need to do to increase the power of the "402th" engine in garage conditions? If the motor is worth a decoded head of the block with a height of 98 mm (ZMZ-4021), you can shoot the surface of the GBC, remove 4 mm. Thus, the motor will be adapted to work on gasoline AI-92. When assembling piston group It does not hurt to fit all the pistons and rods by weight, the difference between a pair of a rod piston in all cylinders by weight should not exceed 5 grams. Also, to reduce friction between the sleeve and the piston, the piston skirts can be filled with small emery paper (№1000), but they do that when they do not hurry with the engine assembly, as there will be a lot of time to polish. It will also be harmless to handle the inlets in the collector, as well as in the block head - will add several horse power.
Some car owners are resetting cylinder sleeves under repair pistons +1 mm, although there is a repair of +1.5 mm on the Volga Motors 402, only it is rare enough. Boring the sleeves gives a slight increase in cylinders, respectively, and power.
The most popular type of modernization of ZMZ-409 - chip tuning. To do this, the firmware is changing in the DVS control unit, which also helps to improve the technical characteristics of the motor, power gain.
The engine replacement to the more perfect is also a version of tuning, many car owners seek to establish a more modern motor, but it should not always be more. DVS with a large amount not too economically spending fuel, and therefore often on the UAZ masters of cars put diesel from which before gasoline engine There are two main advantages:
- fuel consumption with diesel noticeably less;
- diesel engine has the best burden at the same volume of cylinders with a gasoline engine.
Russians diesel engines ZMZ are not distinguished by high reliability, so replacement gasoline motor Power units of imported production are considered. Often, motors are installed on UAZ "loaf":
- TD27 (Nissan, 2.7 L);
- Om616 (Mercedes, 2.4 l);
- 1kz (Toyota, 3.0 l).
As a rule, an import motor is paired with a foreign transmission and distribution, so the need to customize the aggregates under bridges, make changes to the suspension. Of course, it is possible to put a modern turboodiesel on the "loaf", for example, Cummins 2.8, but it is worth such force aggregate Dear, and the Russian dielair, he tolerates badly.
Car suspension UAZ
Device
The car suspension consists of four longitudinal semi-elliptic springs working together with four hydraulic piston duplex shock absorbers.

Shock absorbers are designed to clean the oscillations that appear during the movement of the car, and increase the smoothness of its stroke.
On all UAZ -451m and UAZ -452 cars, springs are installed, the ends of which are fixed in rubber pillows.
Car UAZ -451m front springs have eight sheets, rear springs for ten sheets.
On UAZ -452 cars, the same front and rear springs are installed, each of which consists of 14 sheets.
The length of all the springs in the straightened state (between the centers of pillows) is 1200 mm.
To prevent the population capability while driving the rear end of the rear springs on cars, a stroke strap is installed rear bridge. In fig, 97 shows the installation of the rear axle of the AMA -451M car vendor, and in fig. 98 - Belt-limiter 15 UAZ -452 cars.
Spring sheets are made of special profile strip steel and are thermal and shot blasting.

Maintenance
Maintenance Spring. Through one thing-1 you need to check the springs.
Each time-2 is necessary:
- Check the inspection of the springs and rubber stem rubber pillows;
- When detecting significant wear or destruction of spring pillows, they must be replaced by new ones. Especially needed to monitor the state of the front springs, since significant wear of the supporting surface of the pillows causes the wagging of the wheels and worsens the car handling;
- evenly tighten the nuts of the Sprinkle Sprinkle.
As needed when the screen appears, the springs should be cleaned of them from dirt and lubricate. For lubrication, the front or the rear end of the frame is raised to the jack so that the wheels do not touch the floor. Pushing the screwdriver of the ends of the springs, lay in them a graphite lubricant.
Maintenance of shock absorbers. Each time-1 check the state of the shock absorbers. When the leaks appear through the gland tighten the gland nut.
Each that-2, check the inspection of the front and rear shock absorbers and, if necessary, add the amortic liquid to the lower edge of the bulk opening, without removing the shock absorbers from the car. When plot, you need to dial a shock absorber rack and, shaking the lever, fill the liquid with small portions.
Tighten the fastening bolts of shock absorbers and racks.
Once a year, when performing the next maintenance of TO-2, remove the front and rear shock absorbers, unscrew the plugs of the valves, remove the valves and rinse with gasoline. Before assembling the details you need to dry.
When pouring fresh liquid, comply with the purity, not allowing the slopes of the slightest particles of dirt.
Under the plugs of the valves, install new aluminum gaskets with a thickness of 0.8 mm. Valves can not be confused by places.
Cylinder covers do not shoot.
After putting the shock absorbers on the frame to give drain excess fluid.
Removal and disassembly of suspension nodes
To repair the suspension nodes, it is necessary to remove them from the car and disassemble. After disassembling, cleaning and washing parts, check their condition and identify the suitability for further work.
Removal springs. To remove the springs, install the car to the inspection ditch and perform the following operations:
- install the front (or rear) part of the car on the stand, remove the wheel, disconnect and remove up the shock absorber lever;
- raise the jack of front (or rear) bridge;
- unscrew the fastening nuts and remove the stepladder;
- unscrew the fastening bolts of the housing covers of the front and rear ends of the spring and remove the covers;
- Remove the resor along with rubber pillows.
The springs are installed on the car in the sequence, reverse removal.
Before installing the springs in the housing, it is necessary to straighten the sprouts. This use a jack or special device.
When installing the spring, pay attention to the position of cups, glued to the ends of the indigenous sheets; Fully closed cups at the front springs should be located on the front (movable) end, and the rear springs - in the rear (movable) end.
Shock absorbers. Install the car on the inspection ditch and perform the following operations.
On the front shock absorber:
- unscrew the nut and knock out the lower finger of the shock absorber pillar (UAZ -451m car);
- unscrew the bottom of the shock absorber rack, remove the shock absorber lever along with the rack up and remove the pillows and jacks of the shock absorber pillow;
- unscrew the nut, knock out the shock absorber rack finger and remove the rack.
On the rear shock absorber:
- unscrew the shock absorber rack fastening nut to the rear axle crankcutter, remove the shock absorber lever along with the stand up;
- unscrew the nuts of the shock absorber mounting bolts, remove the bolts and remove the shock absorber;
- Unscrew the nuts, knock your fingers and remove the rack and hand.
Installing shock absorbers in place are needed in order to remove.
When wearing in the sleeves of the shock absorber lever or the eyelers, it is necessary to score with the mandrel mandrel and replace them with new ones.
Before pressing the rubber sleeve, its outer surface, as well as the inner surface of the ear, should be lubricated with liquid soap. Bronze sleeve pick up steel, put on one another. In this case, the inner surface of the bronze sleeve lubricate the thin layer of technical vaseline or solidol. Spending sleeves are pressed into the rubber sleeve.
When the shock absorber rack is bent, it needs to be right or replaced.
To connect the lever of the shock absorber with a stainstick in the rack's ear, installed from the hole with a large diameter (9.5 mm).
General instructions
As a springs assembly. After disassembling and changing the defective sheets to collect the refrigera, performing the following instructions.
Before assembling springs, lubricate with graphite lubricant.
The threaded end of the spring bolt is sprinkled or smithing a hammer with shock.
The end of the rivet of the clamp after the ripple to the spersion sheet should not perform above the leaf surface.
Spring clamps after compression should not prevent the free movement of sheets during the springs.
After assembling the resor, paint alkyd-styrene enamel MS-17.
Spring bracket cap bolts and nuts stewdrops tighten after sediment Spring from weight installed on the engine and body car.
The springs of the UAZ -452 car must be sorted by deflection boom under load of 600 kg into two groups:
I group - a 15-25 mm deflection arrow;
Group II - Arrow of a 15-5 mm deflection (labeled green paint on a cup).
Scheme measurement of the stem deflection arrows is shown in Fig. five.
On disassembly and assembling shock absorbers. In the event of a malfunction in the work of the shock absorber, donate the shock absorber rack, as described above, and check the hand of moving the shock absorber lever up and down. The movement of the lever without much effort is first, and with further rotation with a significant force indicates an insufficient amount of amortic liquid in the case.
The movement of the lever without much effort from one extreme position to another indicates the almost complete absence of a damping fluid in the case or to clog the valve.
The reason for the very tight movement of the lever can be a breakdown of the shock absorber details or the appearance of defects they (deformation, jackets, cracks).
When disassembling (partial) shock absorber, you need to keep in mind the following.
With partial disassembly, possible in the garage conditions, it can be removed: a bulk plug, valve plugs and work valves. You should not remove the cylinder covers.
When disassembling and assembling shock absorbers, it is necessary to ensure special cleanliness of the workplace and follow the following instructions.
Do not clamp a shock absorber for the housing into vice, since the cylinder walls can be deformed. The shock absorber must be attached by bolts to the device (plate, carbon) through the holes in the housing, and the fixture is fixed in the vice. The shock absorber can also be clamped in vice for the lever.
When assembling the shock absorber, the valves cannot be confused by places in order to avoid incorrect operation of the shock absorber (the return stroke valve has one spring, the pricing valve is two springs), and it is also not recommended to rearrange the corresponding valves from one shock absorber to another.
Fig. 5. Memor of the springs of the springs
When assembling shock absorbers to ensure tightness, aluminum gaskets under the plugs of valves are needed (children. 11-2905092) replace new. Packing thickness - 0.8 mm.
The shock absorbers need to pour 145 cm3 of the amortic fluid. The level of fluid in the crankcase in the operating position must reach the lower edge of the bulk hole. When filling with fresh liquid, you need to turn the lever until the level decreases.
To reject the shock absorbers' covers (having holes with five grooves) you need to use a special key with your paws, to avoid damping of covers and loss of tightness.
Lever, roller and cam with disassembly is not recommended.
It must be borne in mind that at the factory of the shock absorbers and pistons, in order to relieve the selection, they are sorted into 4 groups in terms of diameters of cylinders and pistons.
The piston should move in a cylinder without jealous.
The angle of the total rotation of the lever must be at least 70 °.
The shock absorber after the assembly is tested by hand on the smoothness and silentness of the action, tested on the tightness of pumping on the stand and regulate.
Widely applied not only in the territory Russian Federation, but also abroad. Device front Bridge UAZ loaf allows you to connect four-wheel drive For overcoming off-road. Due to this, the car is characterized by high rates of patency at difficult areas of crossed terrain.
How the front axle UAZ is arranged
The UAZ Loise Bridge circuit allows you to determine that it consists of several nodes:
- Composite carter;
- Gearbox;
- Half
Below is the device of the components of the front bridge of the UAZ Buanka car.
Carter
Carter Bridge Car UAZ Buanka consists of 2 parts. Parts are mounted with bolts among themselves, while forming a cutter gearbox. Parts of the crankcase are equipped with fasteners for installing the springs and shock absorbers.
Important: When using a car, the lubricant in the crank is heated and expands. In this case, the pressure in the cavity of the crankcase increases. To prevent violation of the tightness of the bridge crankcase, a breathing valve is provided. It is installed on the casing of the front axle of the OAZ front axle and is necessary for the crankcase cavity message with the atmosphere.
At the edges of the bridge there are rotary mechanisms. They are necessary to control the car. Mechanisms are hinge connected to the edges of the crankcase. Rotary mechanisms are installed trumps. They are needed for a hub joint with the hubs of the car. To reduce the degree of friction, the hub is mounted on roller bearings.
Reducer
The Reducer of the Front Bridge UAZ Buanka consists of the main transmission and the inter-track differential. When the front axle UAZ loaf is on, the torque from the gearbox is entered through the drive shaft on the gearbox flange. It is installed on the same shaft with the main gear gear.
Rotating, the leading gear transmits the torque of the slave gear. Compared to the lead gear, it has a large diameter. This allows you to reduce the torque transmitted from the transfer box.
Help: the teeth of the gear gears of the main transmission of the UAZ car reducer are located at an angle. This prevents the teeth of the gear on each other, thereby reducing the noise level when the car is moving.
Inside the driven gear is an inter-wheeled differential. It consists of conical satellites and their axes. The differential mechanism includes slots of the semi-axes. Differential allows when the car turns to reach the difference in the speed of rotation of the wheels of one axis. You can also read about.
Pointers
The front axle of the UAZ car loaf is a shaft with slots at the edges. On the one hand, the slots are installed in the ratio differential. The second side of the semi-axis drives the wheel hub. Transferring torque from the front bridge gear to the wheel mechanism is carried out using a shruss. It allows you to transmit torque regardless of the angle of rotation of the wheels.
A distinctive feature of the front bridge of the UAZ Bukaka car is the ability to turn off the wheel hubs from the semi-axle. This is necessary to prevent the wear of the rotating parts of the gearbox with a long-term coating of good quality.
Possible faults of the bridge and their causes
The front axle of the UAZ Bukaka car is reliable and unpretentious to the operating conditions. Most frequent malfunctions this is:
- Carter sealing disorders. An excessive pressure arising from the heat of the oil during the movement of the car leads to the violation of the sealing of the crankcase. To prevent malfunction, it is necessary to regularly check the performance of the breathing valve;
- Bearings were worn out. It occurs as a result of improper operation of the front bridge of the UAZ Buanka car. Switching the front axle UAZ loaf to the included position when coating good quality leads to rapid wear of the gearbox bearings. To prevent the bearing breakdown, it is necessary to connect the front axle only to overcome off-road;
- Increased wear of rotating parts. Is due to poor quality lubricant. It is necessary to regularly change the oil in the front bridge. The cause of the malfunction can be water that falls into the cutter gearbox when overcoming the fusion. In order to avoid water from entering the crankcase of the gearbox, the breathing valve is equipped with a hose that is fastened under the cover of the engine compartment.
- Violation of the work of the inter-wheeled differential. Often arises due to the wear of the pussher. To prevent breakdown, it is necessary to regularly examine the mechanism of the pivot for the presence of a backlash. Upon exceeding the permissible indicators, it is necessary to replace the pivot;
- Master gear bearing bearing breakage. Comes due to violation of the work of the Cross cardanian Vala. It is necessary to regularly check the integrity of the cross.
- High degree of wear of conical satellites or their axes. The integrity of the conical satellites and their axes affects the pressure difference in the tires of the wheel of the front axle. In order to avoid breakage, it is necessary to constantly monitor tire pressure.
Connection diagram UAZ Buanka
Some car owners are wondering how the front axle is turned on on UAZ Buanka? The inclusion of anterior bridge is carried out in two ways:
- The lever installed in the cockpit. The lever manages a handout. When the front axle of the UAZ loaf is turned on with the lever installed in the cabin, the torque from the dispensing box is transmitted by cardan shaft to the leading axis.
- With the hub installed in the wheeled mechanisms. It is possible to disconnect the hub of the leading bridge from the semi-axis. The inclusion and shutdown of the front axle of UAZ loaf with the hub allows you to reduce the load on the gearbox when driving through solid coating.
Important: After turning off the couplings located in the wheeled mechanisms, the connection of the full drive lever from the salon will be impossible.
To turn on the coupling, it is necessary to remove the protective axis hub cover. With the hexagon, tighten the clutch cap until it stops. Slots of the semi-axes will be engaged, and the hub will be connected to the reducer. To disable the coupling, you must perform the procedure in the reverse order.
Connect the four-wheel drive by the lever installed in the cabin, it is necessary as follows:
- Turn off the clutch clutch;
- Install the gearbox lever is a neutral position;
- Translate control lever to extreme front position;
- After performing actions, the four-wheel drive will be included. Turn off the four-wheel drive is necessary by transferring the lever to the extreme reverse position.
ATTENTION: Before turning off or turn on the front axle on UAZ loaf, it is necessary to turn off the clutch clutch. To do this, squeeze the clutch pedal located in the cabin.
Removal and repair of the front bridge
The front axle UAZ loaf has a simple device, which allows you to repair with your own hands in the presence of minimal technical knowledge. To remove the node from the car you need:
- Car on the observation pit, an overpass or lift;
- Cut the car to prevent spontaneous rolling. For this sub rear wheels establish anti-digitory devices (shoes);
- Subdominate the car's frame. To simultaneously raise both sides, the jack is installed in the front of the frame in the center;
- In order to avoid injury to the car of the car, install on specialized supports;
- Unscrew the screw mounting bridge to semi-elliptic springs;
- Dismantle the craving steering tower;
- Unscrew the shock absorbers fastening nuts;
- Dismantle the shock absorbers;
- Remove the main axis of the car.
Help: If you need to replace the elastic pillows installed in the brackets of the spring, the axis is dismantled along with the springs. For this, instead of the nuts of the stepladder, bolts are unscrewed, fixing the cover of the brackets.
Perform repair and adjustment of the front axle of the UAZ car Buanka can a person having certain skills in the repair of equipment. To diagnose malfunction it is necessary to conduct a visual inspection of the node. FROM outdoor UAZ Carter is viewed for oil flows. The presence of oil drills indicates the depressurization of the crankcase. To eliminate the leaks of oil, it is necessary to replace gaskets and glands. When installing the gasket is lubricated with sealant.
After disassembling the node, it is necessary to pay attention to the integrity of the bearings. Forted details must be replaced by new ones. Special attention Pay out the wornity of rotating parts. With exceeding permissible norm Replace worn parts should be replaced.
Attention: the leading and driven gear of the main gearbox is replaced simultaneously. The replacement of one of the gears of the main transmission can lead to its rapid wear to the spoiled teeth of the second gear.
It follows from the above that the front axle UAZ, due to its design, improves specifications car. The front axle is equipped with rotary mechanisms. This allows you to transfer torque from the gearbox to the wheels vehicle Regardless of the corner of their turn. It is possible to disagne as a gearbox and wheel mechanisms by turning off the couplings.
