Any motorist can make repairs front axle UAZ Loaf and UAZ 469 do it yourself. This work is not difficult. Structurally, both of these models are similar. This is especially true for the suspension. Frame construction implies easy dismantling of the front axle and high reliability of the vehicle. There are some differences in leaf spring and spring suspension. But these features do not greatly affect the complexity of the work.
Almost no special tools are needed for repairs. All work is carried out with a minimum set of tools available to each driver.
Regular work
Do-it-yourself repair of the front axle of UAZ Loaf and UAZ 469 is simple. Most often, during operation, it is necessary to carry out various preventive work. As a rule, they do not require removal and disassembly of the bridge. The list of care actions includes:
- The pivots are checked for gaps;
- Threaded connections must be tightened periodically;
- Convergence is checked;
- The requirements of the parts lubrication tables are met.
Withdrawal
The repair of this unit begins with the dismantling of the bridge. On a loaf and a "goat", these works are performed identically. There are only minor differences. When performing repair actions, you need to be extremely careful. Removing the bridge consists of a series of simple steps:
- You should start by ensuring that the vehicle is stationary. For this, anti-rollback brake pads are installed;
- Further, on the "goat" they turn off brake pipes from the hoses. On the Loaf, the tubes have transition pipes. V this case the hoses are disconnected from the nozzles;
- Remove the nuts securing the lower shock absorber cups. This element is the same on both machines.
- Next, unscrew the bolts connecting the drive gear flange and the front universal joint. Before that, you need to fill in the threaded connection;
- Remove the thrust from the bipod. The nut on the ball pin is twisted;
- Unscrew the nuts that secure the spring ladders. Disassemble them with overlays;
- They will jack up the frame in front of the car, roll out the bridge.
Parsing
When carrying out repairs, it is necessary to put the unit on the stand. This will make the disassembly task easier. After that, the wheels are removed. Then proceed to disassembly:
- Dismantle the bipod. The nut that secures the thrust pin and the steering knuckle lever is twisted;
- Next, unscrew the bolts securing brake drums... At the same time, they remove the clutches used for wheel shutdown;
- Go to disassembling the hub. Begin this work by straightening the edges of the locking washer. Next, a nut with a locknut is twisted, this allows you to remove the washer immediately with the inner ring and roller bearings of the hub. After the rest of the hub is removed (see article "");
- Remove the brake shield, this is done by unscrewing the bolts. It is necessary to remove the pins with the knuckle hinges;
- The steering linkage is disassembled, for this you need to unscrew the fastening nuts of the trapezoid;
- To remove the ball joint, the bolts of its attachment to the axle shaft are unscrewed. Dismantle the support-restraints. The supports are pressed out;
- Remove the shims used for adjustment from the knuckle and the lever. Next, unscrew the nuts securing the upper pad of the king pin. Also do from the bottom. Remove the ball joint seal. After the pivots are pressed out. Disassembly is complete.
Repair... After disassembly, all parts are washed in gasoline and lubricated. Defective ones are replaced with new ones. The assembly takes place exactly the opposite, while it is necessary to clarify some of the nuances of the process.
When replacing the pivot bushings specifically in the ball bearing, after pressing, they must be tightened to 25 mm. Put grease inside. Do-it-yourself repair of the front axle of UAZ Loaf and UAZ 469 is not so difficult, but accuracy is needed. For example, when installing a ball seal, the ring for it must be impregnated with hot oil. After assembly, the functionality of the bridge is checked using a stand.

- The requirements of the parts lubrication tables are met.
It is imperative to visually inspect the main components. Particular attention is paid to the serviceability of the fastening bolts. All locking elements must also be securely reinforced. Check the angle of maximum rotation of the wheels. It should not exceed 28 degrees. If indicators differ from those indicated, you need to make an adjustment. Also, always check that the king pins are properly tightened and functioning. Untimely elimination of minor faults can lead to the need for overhaul of the front axle.

UAZ 452 "loaf" is a fairly reliable Soviet four-wheel drive SUV. The main breakdowns of this car are associated with leaks of lubricating fluids from the engine, gearbox (gearbox), front and rear axles, constant velocity joints (CV joints) and hubs. The main reason for the formation of such leaks is that the material from which the original seals and gaskets of the above units are made is partially corroded under the influence of modern lubricating fluids. Due to poor lubrication, moving metal parts are subject to severe wear and must be replaced periodically. It is necessary to carry out preventive maintenance of the UAZ 452 at least once a year, change leaking oil seals and gaskets, and adjust the clutch.
The problem is that finding a factory manual for these SUVs is quite difficult. Therefore, we bring to your attention an instruction that will allow you to repair a car yourself.
As you know, the repair of a car engine begins with its dismantling. And only then the disassembly is carried out, replacement damaged parts and assembly. Overhaul of a power unit is not an easy task, therefore, it is not worth doing it yourself, without the help of experienced craftsmen. But you can change the oil seals yourself.
The factory repair manual for the UAZ 452 vehicle states: to remove power unit, you need to lift it up from the engine compartment. With this method of dismantling, you need 2 strong pipes (longer than the width of the cab) and the help of 2 people.
That's it, the power unit is removed.
Check if you need overhaul engine, easy: you need to put your hand to the open oil filler neck of the running engine. If the palm pushes out, then disassembly is required.
Quite often in UAZ 452 cars it is not adjusted free run clutch pedals. This leads to increased wear of the driven disc and the need to replace it early. Adjusting the clutch of a UAZ 452 car is quite simple.
Clutch drive design.
- Clutch pedal.
- Brake pedal.
- Springs.
- Oiler.
- Thrust bearing.
- Coupling.
- Clutch spring.
- Lever arm.
- Adjusting bolt.
- Fork.
- Pusher.
- Fork spring.
- Traction.
- Grease nipple.
Clutch Pedal Adjustment
The factory manual for the repair of UAZ wagon-type vehicles sets the following unit parameters:
- the gap between the pressure bearing and the heads of the levers screws - 2.5 mm;
- pedal free travel - 28-35 mm;
- full pedal travel - 145-155 mm.
Clutch adjustment is carried out as follows.
- We measure the free and full travel of the clutch pedal with a ruler.
- Remove the pedal springs and clutch fork.
- We loosen the pusher nut.
- We unscrew or twist the thrust end of the pusher until the recommended parameters are reached.
- Tighten the pusher nut.
- We put the springs back on.
After that, we check the combined and full pedal travel. If they correspond to the recommended parameters, we start the engine and check the operation of the clutch while driving. If it does not drive or skid, the clutch adjustment is complete. If something bothers you, we repeat the procedure until the desired result is obtained.
The domestic UAZ spring is almost universal for the Patriot, Hunter and Pickup models, as well as their modifications. Elements differ only in the number of sheets that affect the carrying capacity of the vehicle, as well as the difference in geometric dimensions... In this regard, the four-leaf elements from the "Pickup" and "Cargo" are quite realistic to install on the "Patriot" and "Hunter". The increase in carrying capacity will be about two hundred kilograms. Consider the features of standard and modified parts.
Spring Front Suspension Models
A UAZ spring of this type is produced by the metallurgical plant in Chusovoy. Distinctive feature an element of ChMP production is the presence of a sticker and a stamp on the tightening clamp. The name of the manufacturer, the date of production of the part, as well as the OTK mark are displayed here.
In addition, each spring is marked with a label, since the brand is not always easy to see. Additional information: barcode, spring number, GOST standard.
Model 31512-2912012
This UAZ spring is a small-leaf rear part, which was mounted as standard on models 31512, 31514-10, 3160. The element is also suitable for Patriots and Hunters, as well as their modifications.
Distinctive characteristics of the node in question:
Standard spring UAZ type 3163-2912010-02
This standard small-leaf element has the following characteristics:
The UAZ Patriot springs under consideration are also suitable for models 315148, 315143, 315196, Hunter, Simbir and Cargo. This part differs from the analogue 315112-2912012 in its length and clamping clamp, as well as in the presence of spacers between the sheets.
Four-sheet option 3153-2912010
The rear small leaf spring of this type is mounted on the index: 3153, 3159, 3162. The part can be used on models 315148, 315143, "Hunter", "Patriot", 3163, 2362, "Cargo". The modification in question is very popular among car owners from Ulyanovsk manufacturers.
Below are its main parameters:
Modification 3162-2912010
This UAZ spring is a standard part that is mounted on rear axle practically all cars of this brand, including Patriot, Bars, Hunter and Cargo. On sale, this spring is quite rare, therefore it is not very popular among owners.
Part characteristics:
Version 2360-2912010
These UAZ Patriot rear small leaf springs have the following characteristics:
- Assembled element weight - 22.3 kg.
- Control load, Pk, daN - 643.75.
- Full / calculated length - 1.41 / 1.35 m.
- Package height - 49.6 mm.
- Steel type - 50HGFA.
- The number of sheets is four.
In the standard layout, the part in question is mounted on the "Cargo", "Patriot", "Pickup", "Hunter", "Simbir" and some others models. As evidenced by the reviews of the owners, this product is not particularly popular. Users give preference to modifications from four sheets under the index 3153-2912010.
Gain
Often, UAZ repair and tuning concerns shock-absorbing devices. Old straight springs on the "Hunter" can be replaced with a reinforced sixteen-leaf analogue. As practice shows, the standard elements of this unit do not differ in high quality steel, they quickly deform and crack. Consequently, the modernization of the unit is justified.
After the installation of reinforced springs, the car will become much higher, and the power reserve will increase. The car will get slightly stiffer, which is not a significant drawback as we are looking at an SUV. But driving performance and the cross-country ability of the vehicle will noticeably delight the owners of domestic jeeps. The following is presented step-by-step instruction on the installation of new elements.
Spring fastening UAZ
Installation reinforced spring is not too difficult. The work is carried out in the following order:
- The rear of the machine is lifted first until the wheels begin to hang. A safety beam or support must be installed.
- Then the wheel is removed.
- Installation in progress additional support under the bridge. A regular jack is quite suitable for this.
- The ladders and cups of the block are unscrewed.
- The shock absorbing element is removed from the bottom mount.
- The bridge descends.
- The old spring is dismantled.
- A new element is being tried on.
- The bridge is lowered to the optimum point for installing a new part.
- The element is placed in bowls located on the frame, the hanging part is supported by a wooden bar, which will not allow the spring to jump out until the final installation.
- A prepared new unit is mounted, secured with stepladders, but has not yet tightened to the stop.
- The bowls are exposed at the same place of installation.
- The bridge rises until the springs settle on the pillows.
- The wheel is flanked.
- The lower cups are twisted.
On this, the repair of the UAZ in terms of replacing the springs can be considered ready. In order for the part to be installed to sit in its place better, it is advisable to load the rear of the car during work. After carrying out the work, check the car in action at low speed. If there is no discomfort or squeak, the upgrade was successful.
In conclusion
The parts in question are responsible for the behavior of the car on different types soils. Unfortunately, domestic standard UAZ-469 springs are not of high quality steel. Therefore, many owners resort to replacing this unit with a reinforced version, since the standard element often breaks and deforms on bumps and potholes. It is worth noting that most of the standard springs for Ulyanovsk SUVs are interchangeable, which makes it easier to repair and maintain the car.
Lifting options for UAZ Loafs
The owners of the Loaf, starting the tuning of this car, first of all ask themselves the question: "How to raise a UAZ loaf?" We will try to answer this question in this article. So, first of all, we will consider the ways of the UAZ elevator. This could be:
- UAZ body lift
- Loaf suspension lift
Both options have advantages and disadvantages. So, the loaf body lift is easier to implement, and also stands out with a greater degree of safety. This is explained by the fact that this method of elevator only slightly shifts the center of gravity of the car, which contributes to ensuring the stable behavior of the Loaf when cornering and other difficult areas tracks.
If we talk about a suspension lift, then there is some danger due to an increase in the center of gravity. But at the same time, this method significantly changes the cross-country performance for the better.
Choosing a set for the UAZ elevator loaf
As we can see, there are several ways to raise the Loaf. Therefore, it is possible to determine which lift kit UAZ Loaf will be needed only by deciding on the choice of the lift method. If you plan on doing the lifting yourself, you can buy an elevator kit from the store. Such kits are different in the composition of the parts and elements included in them.
So, a Loaf lift kit can contain:
- spacers "spring - frame";
- spring-to-frame spacers
- bolts;
- nuts, etc.
Changing wheels
As you know, the passability of the car directly depends on the wheels. Considering that the wheels of the UAZ are shod with rather hard and not too large rubber, before proceeding directly to the elevator, it is necessary to mention the wheels. In addition, the tread pattern on the Loaf's tires leaves much to be desired. All this suggests that it will not be superfluous to install on legendary car suitable imported wheels.
As an option, when choosing new wheels for the UAZ "Loaf" car, you can use BF Goodrich 33x10.5 R15 tires, and, accordingly, discs with a diameter of 15 centimeters. As for the choice of disks for them, it depends on the wishes of the owner. These can be light-alloy or light-alloy wheels. Or you can leave the usual regular wheels.
However, it is not worth stopping at this stage, because such tuning makes it difficult to control, since at sharp turns the front wheels cling to the edges of the steering rods, and when the effect of crossing the axles appears, the wheels are located directly on the sides of the arches. This causes the tires to rub against the fender. Therefore, the UAZ Loaf body lift becomes an indispensable stage of tuning after the installation of the wheels.
As strange as it may seem, the UAZ Loaf's frame is attached to the body with ten furniture bolts, six of which are located in the area of the passenger seats, two behind the front wheel arches, and two more at the feet of the driver and passenger. At the bottom, the bolts are secured with second nuts.
Before proceeding with the dismantling of the bolts, it is necessary to disconnect the battery, disconnect the earth from the engine - behind the bonnet compartment and raise the car on a lift.
- Disconnect the wires from the starter;
- Disconnect the radiator mounts from below or from above;
- We detach the rods of the drive of the transmission lever and the rod of the brake booster;
- Drain all the coolant and remove the hoses that are connected to the UAZ Loaf stoves;
- Disconnect the brake pedal rod to the vacuum booster;
- Disconnect the tubing leading to the tank control valve.
The last point may not seem so important, but non-compliance with it can lead to the plate deflection under the mount, as a result of which it will have to be aligned.
When lifting the UAZ Loaf with your own hands, be careful and careful, since the fasteners on such a car are usually rusty and outdated. If the bolt turns in the body, then it cannot be held. This creates additional difficulties in welding a nut or bolt to it.
To do everything correctly, it is necessary to hold one nut with a wrench, while unscrewing the lock nut with the head, and after that the main nut.
Next, you should lower the car on the wheels, since there will be no more work to be done under it. We also detach the steering column and detach the boot on the floor. And you can start lifting the body above the frame. The rise must be started from the back of the Loaf. The lifting height should eventually be about 10 centimeters.
It will be a good idea to hedge by placing a wide wooden bar between the frame and the body.
We unscrew the standard bolts and increase the holes for them up to 12 mm by drilling. Next, you need to do some work with the spacers. Inexpensive and suitable option ordinary hockey pucks are used as spacers. The next steps will be to insert the spacers, bolts and tighten the nuts gradually, starting at the rear of the body, continuing in the middle and ending at the front.
As a result, the body will rise by 6.5 centimeters. It remains only to fix everything and you can put large wheels.
Pros and cons of suspension lift
Now let's consider the next way to carry out the UAZ Loaf lift - a suspension lift. As already mentioned, this method has both pros and cons. There are two main advantages of the suspension lift on the UAZ:
- improving the performance of the Loaf's passability, provided that the wheels remain in place, and the other part rises up;
- the ability to install large wheels that did not fit into the arches of the UAZ before the suspension lift.
Well, the main disadvantage of this method is the inevitable increase in the angles. cardan crosspieces... In this case, cardans are included in the work for wear.
There are several options for a suspension lift. Let's take a look at some of them.
Installing longer spring earrings
The simplest and most affordable option is to install longer spring earrings. When carrying out a suspension lift in a similar way, you should not get too carried away with this, so as not to install too long. Spring shackles that are too long can adversely affect suspension performance and affect handling. To avoid problems in handling, it is recommended to pull the earrings with a tie in the center.
Axle-spring spacer
Without disturbing the design of the springs, it is possible to slightly raise the Loaf's suspension by installing a spacer between the axle and the spring. At the same time, there is no need to wait for a large elevator; here it is also recommended not to get carried away with the process.
Of course, when installing such a spacer, it is necessary to decide on its fixation in the mounting place, and also calculate that the length of the step-ladders of the springs is sufficient. It is also possible to restore old springs, or purchase new ones. There are also special items for such tuning on sale, but they are usually very expensive.
Springing the springs is not as difficult as it might seem at first glance. This process is useful not only for the suspension lift, but also for the purpose of making the hard UAZ suspension soft enough. However, despite the fact that there is an improvement in the quality of the suspension from this method, they are very insignificant.
If you decide to give it a try, you first need to cut, grind, or buy spacers, rubber, conveyor belt and metal. And most importantly, when lifting the suspension of the UAZ, longer-stroke shock absorbers will be required, since the rebound from the former will begin earlier.
In conclusion, I would like to note that the main thing is to know when to stop in everything. Taking up the tuning of the UAZ 452 with your own hands, remember about your safety. After all, you will not have a guarantee with your own hand execution of the Loaf elevator.
Subtleties when starting the UAZ 469 engine
Cold start at positive temperature
Starting the engine at positive temperatures has its own characteristics. First you need to set the gear lever to neutral, pull out the control knob for the entire air damper of the carburetor by about half and immediately after that, disengage the clutch and turn on the ignition. In this case, the starter must be kept on until the engine itself is started. But don't keep it like that for more than five seconds. The intervals between starting the starter must be at least 10 seconds.
After the engine has started, release the ignition switch key immediately. Then press the choke knob to the position that will provide the lowest engine speed. Now warm up the engine and gradually push down the choke control knob until it stops. It is worth noting that the temperature of the coolant of the engine you have already warmed up should be at least 60 degrees.
Let us immediately pay attention to a very important subtlety during such heating. In no case, when operating the UAZ 469, for accelerated warm-up, drive the car at a high speed crankshaft engine
Starting a cold engine at temperatures up to minus 15 degrees
In this case, first you will need to turn off the oil cooler. After that, close the shutters of this radiator and install a special insulating cover for the radiator lining.
Next, you will need to turn the engine crankshaft with the handle. Turn it about four turns. Then you need to pull out the carburetor choke control knob to the maximum. Next, you need to perform the same actions as when starting the engine at positive temperature.
Starting a cold engine at temperatures below minus 15 degrees
Let us immediately draw your attention to what you need to launch cold engine only after its preliminary warming up with a pre-heater. But if suddenly at the time of launch you will not have preheater, then you can simply spill hot water through the cooling system
If you are doing preheating hot water, then it must be poured into the radiator. Remember to drain the water as it cools from the cooling system. This can be done through a special drain valve. Just remember that after that the system needs to be filled with hot water again. Thus, warm up the entire system until the engine crankshaft starts to rotate. The rotation should be light enough with a well-felt compression in the cylinders.
It is also recommended to warm up the inlet pipeline with hot water, water must be poured onto it carefully, in a thin stream, so that heat can be transferred to the pipeline. After that, you need to turn the fan by hand in order to eliminate possible freezing of the pump impeller in the cooling system. Then everything needs to be done according to the same principle as described in the previous section about starting the engine at temperatures up to minus 15 degrees.
Hot engine start UAZ 469
There are also a couple of subtleties here that should always be kept in mind. When starting a hot engine, you do not need to cover the carburetor choke. It is also not advisable to press sharply on the throttle control pedal, as this can lead to over-enrichment of the combustible mixture and prevent you from starting the engine.
But if all the same combustible mixture turned out to be re-enriched, then all the cylinders need to be blown with air. To do this, gently press the pedal. throttle carburetor to maximum. After very quickly turn the starters the crankshaft in the engine a couple of turns.
Conveyor model platform
The famous "Loaf", thanks to its all-metal body, the model "452" served as a platform for the creation of a whole line of vehicles:
- UAZ 2206 - a minibus for 11 people;
- UAZ 3962 - a car for the ambulance service;
- UAZ 396255 - civil modification of an ambulance for the needs of rural areas;
- UAZ 39099 - promoted under the name "Farmer". Designed for 6 passengers and 450 kg of cargo;
- UAZ 3741 - a van for the carriage of 2 passengers and 850 kg of cargo;
- UAZ 3303 - a flatbed vehicle with an open body;
- UAZ 3904 is a cargo-passenger version that combines the convenience of an all-metal body for passengers and an open body for cargo.
Features of modification with multifunctional control
Variations with the car body did not affect it too much technical equipment... But when the changes affected the controls, they underwent modernization:
- Internal wiring for UAZ;
- Steering column control unit for cornering and outdoor lighting;
- The control unit for the operation of electric wipers on the instrument panel.
Reason for modernization
On vehicles of the UAZ family, the wiper control unit windshield located on the dashboard. And since this did not meet the safety requirements, then on all subsequent modifications:
- it was replaced by a more modern multifunctional unit located directly on the steering wheel;
- began to install a new instrument panel.
Self-upgrade
Cars of new releases already have a multifunctional control unit in the database. But the owners of early releases can convert the car to modern safety requirements with their own hands.
This will require:
- Original wiring
UAZ 2206 - as the most suitable for self-alteration; - Factory instruction diagram
, allowing you to correctly connect the steering column switches to the standard scheme; - Desire to make high-quality editing
.
The work algorithm will be as follows:
- Disconnect the battery;
- We remove the control unit from the instrument panel;
- Disconnect the wires, referring to their compliance with the factory diagram in Fig. 1;
- Remove the standard switches from the steering wheel column.
For alteration, you will need to purchase several new parts:
- Block of multifunctional paddle switches from the UAZ 390995 model;
- Relay for the wiper circuit (best suited from the VAZ model, as well as the 2112 wiring connecting the relay and the switch block);
- Terminal blocks in the amount of 3 pieces (one 8-pin for the side of the steering column switches and two 6-pin for the relay and the standard adapter).
Getting started with the installation:
- We replace the standard connector with a new one;
- We cut the 4x4 wire (in Fig. 2 it is marked with a red cross);
Improved modernization scheme by car enthusiasts
Motorists have improved the alteration scheme proposed by the manufacturer by making some changes to it (in Fig. 3):
- A variable resistor R = 10K was introduced into the circuit, due to which the pause value in the intermittent mode of operation of the wipers can be smoothly changed from 4 s to 15 s;
- Connect the resistor in such a way that the countdown of the operating mode starts from the moment the brush motor stops.
Conclusions: cars of the UAZ family are not only multipurpose unitary off-road vehicles, but also easy-to-maintain vehicles. Almost any car owner, armed with knowledge and colored wiring diagrams, is able not only to restore a failed unit, but also to carry out useful modernization of the car and its individual elements.
Heading
One of the most frequent problems domestic cars is a breakdown of any electrical appliances, the wiring diagram will help you figure it out. The only solution to this problem is to check the status of the fuses. The topic of today's article will be the wiring diagram of the UAZ Loaf car on an injector type engine.
So, this article provides answers to such fairly common questions:

Technical characteristics of UAZ 469
Before proceeding with the intricacies of operating a car, it would be nice to know about its technical characteristics.
Equipped with a 4-cylinder SUV carburetor engine UMZ-451MI with a volume of 2.5 liters. Such a UAZ 469 engine is aggregated with a 4-stage mechanical box gears (with synchronizers in 3rd and 4th gears). Engine power reaches 75 Horse power with a torque of 2200 - 2500 rpm.
Gasoline A-72 or A-76 can be used as fuel. The car has two fuel tank 39 liters each, and fuel consumption at a speed of 90 km / h is 16 liters per 100 km. The maximum speed at full weight- 100 km / h.
Since the engine is the heart of any car, then it would be more logical to consider the subtleties of starting such a unit under various weather conditions, especially if your Uaz 469 is new.
Gearbox removal process
It is quite possible to carry out repair of the checkpoint on the UAZ 452 with your own hands. This requires:
- a set of wrenches, including the wrenches needed to tighten the nuts;
- screwdrivers;
- hammer;
- chisel;
- pliers.
Dismantling algorithm.
The vehicle must be on level ground. It is necessary to drain the oil from the two boxes by unscrewing the drain plugs. Next, the front seats, the hatch halves, the clutch release fork, the transverse frame, the gearshift levers from the boxes are removed.
Removable speedometer shaft, suspension mounts in the chassis, levers brake system... As a result, the outlet to the clutch housing is opened. The box is fixed on it with fastening nuts, which must be unscrewed, then the UAZ gearbox is carefully pulled out together with the transfer case until the splined shaft comes out of the flywheel. The driver will need an assistant to remove the box.
As soon as the disassembly into separate component parts has taken place, the box must be rinsed in kerosene and dried. All component parts are checked for integrity. First of all, this concerns the crankcase, shafts. If the threads on the shafts are damaged, they must be replaced. The machine is considered dangerous to operate if the gears are chipped.
Thus, timely repair of the UAZ “loaf” checkpoint helps to extend the resource of the box.
Meet UAZ 452
The car was a cargo-passenger version of an off-road vehicle with a 4 × 4 wheel arrangement.
The Ulyanovsk Automobile Plant mastered the production of the model back in 1965.
You can evaluate its capabilities by watching the following video:
UAZ 452 is capable of carrying cargo weighing up to 700 kg in the back. In addition, it can tow a trailer weighing 850 kg. Vehicle became very popular not only in Russian off-road conditions, but was also successfully used in large cities in various capacities (pictured in the article).
In particular:
- Like a traffic police car;
- As a fire engine;
- Ambulance car;
- Grocery store;
- Utility vehicle, etc.
Electronic components
The wiring of the UAZ 452 was a simple single-wire circuit.
Structurally, she had the following solutions:
- The role of the second wire was played by the metal body and the assemblies and assemblies attached to it;
- All electronic components and actuators had "-" displayed on the body. The price of such a solution justified the imperfection of the scheme.
Power unit
The engine compartment is located directly in the passenger compartment, as this is due to its design.
Access to components and assemblies is also carried out from the passenger compartment by removing the cover, which:
- Provided protection of the driver and passengers from the penetration of exhaust gases;
- Protected from dust and dirt;
- Served as an additional heating element (passive - from heating).
The previously used motor from "Pobeda" was replaced with a more modern engine from the 21st "Volga". This was facilitated by the launch of a production line at the Zavolzhsky Motor Plant in 1964.
Passive vehicle safety
The Baton's cabover design also raised a number of safety concerns at first. However, a series of crash tests conducted back in 1971 at the Dmitrov training ground proved that in most emergency situations the driver and passengers of the UAZ 452 have a chance to avoid injury.
What is included in the wiring diagram
What features does a car electrician have on old cars produced by the Ulyanovsk Automobile Plant?
Electronic components
The wiring diagram of the UAZ 452 itself is quite simple - single-wire.
By its design, the wiring diagram of the UAZ390995 or another model is characterized by the following solutions:
- The body of the vehicle is used as a mass.
- Any electrical equipment of the old-style circuit on the UAZ 409 or another model, as well as actuators, are equipped with a negative terminal, which is connected to the car body. According to experts, in general, this scheme is imperfect.
According to the instruction manual electrical equipment, the driver should from time to time carry out diagnostics of the condition of the integrity of the contacts. We are also talking about their oxidation. If the driver notices the presence of oxidation on the terminals, he must process them using fine-grained sandpaper.
Engine compartment
In this case, the engine compartment is located directly in the passenger compartment in accordance with the design of the car.
Access itself to electrical diagram and other mechanisms and assemblies are made precisely from the passenger compartment, as a result of dismantling the cover, which:
- Designed to protect the motorist and passenger from exhaust gases entering the passenger compartment.
- Allows you to protect the car interior from dirt and dust.
- It performs the function of an additional heating device, in particular, in a passive way, as a result of heating.
Previously, the UAZ 396255 and other models with a carburetor used an engine from the legendary "Victory", which was later replaced with a more advanced and modern unit. In particular, this refers to the motor from the "Volga". This decision at one time, back in 1964, was facilitated by the serial launch of a production line at the ZMZ enterprise. Despite the fact that many domestic motorists claim that the scheme of the UAZ 390994 injector in engine compartment located in an inconvenient place due to the lack of a hood, it is not. Dozens of years of operation have proven that the absence of a hood does not in any way affect the diagnosis and maintenance of a car.
Passive safety
The very design of the domestic Loaf with the absence of a hood at first raised many questions in terms of the safety of the driver and passengers. As a result of several dozen crash tests, which were carried out back in the early 70s of the last century, it was revealed that the car is no less safe when compared with others. domestic cars... As the results have shown, in the event of an accident, both the driver and the passengers of the car have a good chance of avoiding injury in the event of an accident.
Subtleties of UAZ 469 maintenance
During the operation of each car, its deterioration occurs. technical condition, UAZ 469 cars are also no exception. In order to increase the service life of the machine and prevent malfunctions in time, it is necessary to know the subtleties of its maintenance, namely the subtleties of maintenance of all available mechanisms.
Let's consider some of the most important points:
First of all, pay attention to the frequency of oil changes. It is recommended to do this every 5000 kilometers.
At the same time, during the operation of an SUV, it is allowed to lower the oil by 10-12 mm relative to the lower edge of the filler hole.
It is also necessary to periodically carry out maintenance of the gas distribution mechanism, which consists in cleaning the valves from carbon deposits and lapping them.
The oil filter is changed by unscrewing it from the cylinder block counterclockwise. Before installing a new oil filter its o-ring must be lubricated engine oil... The new filter is wrapped to the extent that no oil leaks.
The crank mechanism of the car needs to tighten the cylinder nuts every 1000 km. mileage.
The engine cooling system must be filled with soft fresh water with a low salt content and during operation periodically remove scale and debris from the system, as well as adjust the fan belt tension.
The clutch mechanism also needs maintenance... In addition to timely lubrication of the clutch release bearing located on the right side of the crankcase, it is also necessary to clean the lower part of the crankcase after driving on muddy roads.
As for the maintenance of the gearbox, it all comes down to periodic lubrication of the part, this should also not be forgotten.
A few more subtleties of the operation of the UAZ 469
Of course, even the manufacturer itself cannot know all the subtleties of the car, so we will try to tell you everything to the maximum. So, a few more subtleties:
- Reverse in the gearbox and downshift in transfer case must be turned on only after the vehicle has come to a complete stop.
- Always disengage the clutch on steep slopes to avoid breaking the clutch disc.
- Never exceed the speed (over 60 km / h) with the front axle engaged, and when driving on dry and hard roads, it can be turned off altogether.
- Also, in no case allow the front axle to engage when the front wheels are disengaged.
- It is necessary to independently periodically check the external threaded fasteners and tightening during vehicle operation.
- Pay attention to the undercarriage of the vehicle and avoid shock loads.
- When driving on particularly dusty roads, to create air pressure in the passenger compartment and reduce dust penetration, open the hatch in the middle of the front end and close the hinged door vents.
Causes of breakdowns
As a rule, the need to replace the main components at the checkpoint arises with their natural wear and tear.
Causes of gearbox breakdowns
The main reason for oil leakage from the gearbox is the presence increased level fuel in the system. For gearboxes on UAZ, high-quality oil should be used. If the liquid is not of the proper quality, then this may cause characteristic noises from the side of the box. When the synchronizer or its parts are worn out, there is always a difficult gear change
Pay attention to the details of the switching mechanism. When the teeth of the gears are deformed, self-switching of gears is often noted.
Finally
Many of us remember the legendary car.
Therefore, his appearance on the show dedicated to the Olympic Games was perceived as part of our glorious history development of the domestic auto industry.
The loaf was honored to participate in the 2014 Olympics
