Before starting the repair of the UAZ body, determine the degree of damage. Sometimes corrosion starts from the inside of the body, although the outer paint coat appears to be intact.
Wash and dry your vehicle thoroughly before scheduling repairs. Inspect the body for damage. Depending on the amount and size of corrosion, you decide whether it will be a DIY repair or send the car to a car service. Overhaul, or medium, is to be done.
So, you decided to repair the UAZ yourself.
After the phosphating primer, walk with an acrylic primer so that the phosphate does not chemically react with the putty.
Now proceed to puttying. Apply the filler in thin layers, smoothing out any unevenness in the metal left after mechanical repairs. The putty is applied at least three times with intermediate drying and sanding of each layer.
The putty surface is primed in one or two layers before painting. Use a spray gun for priming. The dried primer layer is sanded to form a flat surface, to remove possible streaks.
Then 2-3 layers of autoenamel of the corresponding color are applied on the surface to be treated. Each layer is aged according to the time indicated on the can. Keep in mind that can dry times are for room temperature. If the temperature in the room is lower, the drying time of the paint will increase. Air humidity also affects paint drying no less than temperature. Sand each dried layer and wipe off dust with a sticky cloth.
In this chapter, you will learn an interesting way of how to repair a UAZ with your own hands., without using a welding machine.There will not be a word about fiberglass and epoxy - we will leave them for plastic, and for those would-be craftsmen who do not work conscientiously, but only to close the eyes of the customer. Respecting himself and his car, the owner, will not stick fiberglass with epoxy on the body damaged by rust. Because corrosion under such a patch will continue its destructive effect, and as a result, in a couple of months you will get an enlarged hole in this place.
On a metal body, especially if it is a UAZ loaf body, the patches should be made of metal. Find scraps of steel sheet close to the thickness of the body. Using a grinder, or a metal hacksaw, cut out patches from it to size, overlapping the holes on the machine body. Grind the cut out parts so that they do not stick out along the edges of the cuts, try on and grind to the attachment points. Use a strong soldering iron to tinkle the joints. Warm up the patch and put it on the tinned place, solder, while leveling the molten tin so that no protrusions form. Tighten gently with a hammer.
Let the patch cool. Check for strength. If done correctly, strength and durability are guaranteed. Sand your patch. So, using a soldering iron and tin, you can solder small patches on the body, on the door, and process the rest of the body parts. Tin, in addition to connecting it, also protects the metal from corrosion.
This method is no more expensive than fiberglass patches, but more reliable. This method allows you to carry out minor body repairs of any Ulyanovsk car.
Increasingly, the owners of the UAZ 452 model, popularly nicknamed the loaf, come to the need to modernize this machine. The body of the UAZ loaf is lifted, raised to increase cross-country ability. There are 2 lifting methods.
This option is easier to perform, and it provides greater stability to the machine in off-road conditions and when cornering, due to the fact that the center of gravity does not shift. The lifting of the body is carried out thanks to spacers that are inserted between the frame and the body and provide a rigid connection of these elements. The spacers raise the body by 8 cm, and if large wheels are installed, the car will become 15 cm higher. In this case, it is necessary to trim the wheel arches and fenders so that the wheels do not cling to them when cornering, and be sure to hang the mud flaps.
Increases the UAZ's ability to pass obstacles. True, in this case there is a risk of a shift in the center of gravity, the car will lose controllability and stability. The situation can only be saved by a comprehensive repair of the UAZ loaf body.
To begin with, we determine the optimal suspension height;
Please note that lifting is limited by cardan shafts;
You can reduce the likelihood of the machine overturning by expanding the wheel distance.
To do this, take wide wheels, larger discs. Rear axles are changed to "Bars" or "Spacer". Replacing disc brakes will help to increase the inter-wheel distance. Disc brakes from the Volga car are installed without fitting.
During the operation of the loaf, the rear doors are skewed, which begin to open spontaneously.
We start strengthening the UAZ body with our own hands from the floor. For this purpose, we raise the floor and inspect the condition of the underbody. The body is reinforced with a 20x40 profile pipe. The bottom profile is welded to the bottom waves. The first pipe is laid along the edge of the body so that the tailgate rests against it. The second is parallel, at a distance of half a meter. Stiffeners from the same profile are also welded along the side wall of the body. Profiles are installed along the ceiling, parallel to the floor pipes. Thus, the shaped tubes form a frame to which the body walls are welded. Spacers are installed between the upper and lower pipes at a distance of 50cm. The resulting frame is welded to attract sagging corners of the body, so that the rear doors are aligned.If you weld a sheet of steel to the profiles welded to the side walls of the body and spacers, you get a convenient cabinet for fishing rods and guns. A shelf for various little things is also formed on top. In the same way, by installing stiffeners, the side wall and the doorway of the side door are strengthened.
Strengthening the body, increasing the rigidity, and provide "kerchiefs" welded at the junction of the body sheets. Only the kerchiefs must be welded at a distance not exceeding 15 cm from each other.
Before closing the floor, inspect the bottom for rust, sand it, if necessary patch up with welding and treat with rust mastic. While the mastic is drying, cut out the floor parts from the plywood, cover them with linseed oil 2-3 times, let the linseed oil dry and lay the plywood on the floor. Then roll out the expanded polyethylene foam. On top is another layer of plywood coated with linseed oil. Lay the upper floor on top of the drying oil. It can be linoleum, or sheet steel, depending on what is planned to be transported in the UAZ.
The side walls inside also need renovation. Peel off the old panels, clean the side walls of the body from corrosion, treat with mastic. When the mastic is dry, roll out glass wool for thermal insulation, glue the foam polyethylene on it and sheathe the panels with the selected material on top. It can be plywood, and hardboard, and hardboard with dermantine. You decide.
There are two requirements for a car bumper:
Reliability and safety;
External appeal, aesthetics.
Ulyanovsk cars are no exception. Car owners of these cars install bumpers with kangarins on the UAZ 469 or “loaves” body, which, on the one hand, add solidity to the car, and on the other, protect the headlights and radiator from damage.
Requirements are made to bumpers and kangarins that they must comply with safety standards, therefore, in order to avoid problems with a valiant car inspection, we purchase suspensions from a trusted manufacturer.
In the conditions of bad roads, the UAZ becomes exactly the means of transportation that helps to get out literally from any place. Only these SUVs are subject to wear and tear and require repair. The parts and spare parts that are closest to the road surface experience the negative load most of all. From the article we will learn how to repair the body of a domestic car with our own hands.
ATTENTION! Found a completely simple way to reduce fuel consumption! Don't believe me? An auto mechanic with 15 years of experience also did not believe until he tried it. And now he saves 35,000 rubles a year on gasoline! Read more"
In the common people "bobby" (UAZ 469) is the vehicle of the chairmen of large Soviet collective farms, and today the vastness of the Russian hinterlands roam. Another prototype, the "loaf", is a real minivan successfully operated off-road.
Both cars are subject to rapid wear of body parts due to hard operation, constant contact with a moisture environment, etc. On bumps and bumps, the chassis shakes, the elements of which also eventually deteriorate, no matter how good they are.
The good thing is that domestic cars can be repaired even in an open field, having a couple of wrenches with you. If you carry out the repairs in the garage with all the necessary equipment, the result will be impressive.
Often, when removing a layer of paintwork from the body of a used UAZ, the owners find large holes in the body parts. For those who do not have a welding machine, this problem is solved in 2 ways: either a special is called, or the UAZ is taken to the service station. If you have a machine or a familiar welder, everything can be decided on the spot. Also, you can do it yourself if the hole is small, the size of a matchbox.
So, in addition to welding, putty and fiberglass will help to close the hole.This repair cannot be called efficient or super effective, as it has drawbacks. On the other hand, this method is capable of providing at least a month's operation of the car. Then you can show the UAZ to a body repair specialist.
There are other ways to close the hole. In particular, by installing a metal patch. To do this, you need a powerful soldering iron, a piece of sheet (covering the hole completely) and acid.
The algorithm for carrying out this method is as follows:
Before putting the patch, it is necessary to tin the joints;
Put the patch on the hole (it should completely cover the hole);
Solder to the metal body using a high-power lamp.
You need to do everything so that the surface does not have protrusions. Deficiencies that arise in one way or another for a beginner are corrected with a hammer and the final operation with puttying.

Sealing body irregularities is a popular operation of repairmen. Of course, only real specialists, the most experienced craftsmen, can handle this business with high quality, but you can also do something with your own hands.
Surface preparation of the body part is the first thing to do. Spare parts must be perfectly flat and clean. They should also be degreased.
Useful advice. It will be interesting for novice body repairmen to know that in order to detect minor defects in the spare part, the treated area is matted before applying the putty. For this, abrasive P 240 is applied to the body part.
After the surface of the part is degreased, it should be cleaned and degreased again. To eliminate the existing rust, it is necessary to use special agents that effectively prevent the appearance of corrosion later.
The range of fillers today is incredibly wide. They are sold with or without a hardener. In any case, it will be necessary to correctly apply the composition to the body parts, preheating the metal in the sun. In addition, several layers of putty should be applied.
The next stage of work involves grinding. The surface treated with putty will need to be thoroughly polished to a smooth state using a different abrasive - P 120.
Important. When carrying out partial repairs, it is imperative to cover the place of work with masking tape, excluding damage to entire parts of the part.
If in the process of grinding the layers of the putty crumble in some places and the metal is exposed, the composition is reapplied.
There is such a thing as a finishing layer. This is a special composition of the putty, which is applied at the final stage, after thorough grinding of the surfaces of the part. After the finishing composition has dried, the surface of the spare part is re-grinded, changing the abrasive to 240.
Painting can be started only after all the above procedures, when the part of the part is perfectly flat. If body parts have been replaced and need to be painted to match the overall tone, this is usually not difficult. It is only recommended to choose the right paint using either a color code or the services of a professional colorist.
If painting is carried out on the body of an UAZ that has survived repairs to remove a dent or rust, you will have to sweat a lot, again, with the selection of a shade.
Note. Be sure to apply a layer of primer before starting painting. This is the foundation of the procedure. Due to the fact that the metal surface of the UAZ is prone to oxidation and rapid rusting, it is better to apply the primer immediately after filling. A 2-component acrylic primer or phosphate compound is ideal.
The algorithm for self-painting will look like this:
First, a layer of phosphate composition is applied;
After that, a layer of acrylic primer should be applied;
Grinding of soil surfaces is carried out with an abrasive wheel set on a grinder or by hand;
After that, paint is applied, preferably several times, allowing each layer to dry thoroughly.
It will be interesting to find out how the overhaul, full-fledged repair of the UAZ body is carried out with the aim of modernization and tuning. Here's how it looks in stages:
First, the body parts are disassembled;
The fender arches are cut out and the spaces are increased so that instead of the factory wheels, large ones can be put here;
The corrosive parts of the body are cut off with a grinder;
Door sills and steps are also cut if they are in a bad condition. Typically, these body parts rot quickly.
Note. In some cases, in order to modernize, the fuel tank is installed on the UAZ in the salon. This makes it possible to get rid of the uncomfortable side gas tanks, as well as increase the distance from the road surface to the thresholds.
Again, for the purpose of modernization, instead of the thresholds and steps that are cut off, strong metal profiles of 30x60 are installed. They can be folded in three rows and turned into a powerful platform;
The rear wing overhang is also cut in many cases. In truth, he periodically wrinkles or bends. For this reason, it is recommended to reinforce it with a 25x25 profile, qualitatively shaping it in place;
The inner boxes of the rear wheel arches are also replaced, because for the most part nothing remains of them due to corrosion;
All welded seams of parts are thoroughly cleaned, body parts are assembled.
You can optionally carry out body and suspension lifting, rolling / rolling of springs, installing new tires, shock absorbers, etc. You can also carry out major repairs of bridges, brakes, etc.

We have already finished the welding work. We have all the bottom overcooked. It remains to touch up a little, we can say we are at the finish line. We even putty on the body. We'll sand the whole thing and paint it. In general, at the cost of work, all this came out somewhere around 15-16 thousand.
And what have we done? We completely cut out the bottom, digested all the beams. We used the old wings, that is, we boiled them up a bit, everything became normal. Behind the mounts - we also left everything old. It was welded here, the doors are now closing, everything works fine.
Our cost included metal, beams, putty or putty, whatever it is, paint, we took the paint. Everything seems to be about welding. Now let's take care of the interior from the inside. And, by the way, the price also included carpet, then you will see it, this will be the next video. The ceiling, we do not know yet, to do - not to do, maybe we will deal with the ceiling, these are all plans for now.
If you are interested in the process of how we filled up the cracks of the Loaf, then we covered everything with sealant. Normal, tight, and metal, I think, will not walk. This is the hole for the tanks to connect the tanks. For reinforcement, but no matter how powerful it is, this beam, but we welded it all the same so that the body does not play. It's still better than just this.
Instead of a step, we did it a little differently. We made a ledge to stand up with a foot, but here everything is solid, because the body will be stronger, the bottom, it’s easier to live like that.
- Look, our wings are just hanging.
- We welded this first rear beam, screwed it on, checked how our doors close. Now our body does not move, which makes us very happy, finally, and the doors are closing. Hooray!
- Due to the fact that it is, you see, in the cold, it dries up. - You can't even see it, right?
Oh, they made it cool out of rot as new .. at the very UAZ 3303 it was cooked in 94 at the factory from a tadpole into a loaf before so often they did it .. well, of course, they cooked through the ass .. but the car runs through the mud like a tank .. and on fishing you don't have to sleep on the floor, but with the stove installed, it's warm in winter ..
it was necessary to create one under the wheels in a semicircle, but it seemed like nothing, it turned out, but I would also shorten the skirt and boil the skirt with a profile, it would be clear!
it turned out cool, high quality, well done
In vain you are with mounting foam, it is hydroscopic and under it will begin to rot very strongly and quickly.
operator hands you need to cut off for vertical shooting and shit phone
just fucked up .. put the monitor on its side or something ..
4200 two sheets of iron 3000 profile pipe and 3000 consumables stainless steel and lenolium were in stock
bl. if you make a video, then shoot normally
tell me how to restore the side door step Buhan km? The welder said that the metal will not be cooked thin. Is that something to rivet?
if the pillars between the doors are intact, cook a profile for them, we cooked a double electrode with ordinary welding, we cooked a profile to the racks, the rest is a matter of technology
if the rot is cut to normal metal in the video everything is shown
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 heavy 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 disassembly, replacement of damaged parts and assembly is carried out. Overhaul of a power unit is not an easy task, so 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 car states: to remove the 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.
VIDEO It is easy to check whether an engine overhaul is necessary: you need to put your hand to the open oil filler neck of a running engine. If the palm pushes out, then disassembly is required.
Quite often, in UAZ 452 cars, the free travel of the clutch pedal is not adjusted. This leads to increased wear of the driven disk and the need to replace it early. Adjusting the clutch of a UAZ 452 car is quite simple.

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 screw heads of the levers - 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.
Unscrew or twist the thrust end of the pusher until the recommended parameters are reached.
We 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.
You can adjust the travel of the clutch pedal by changing the length of the lower links.
In order to facilitate access to the engine from the car interior, it is necessary to carry out a small modernization of the UAZ "loaf" body on our own.
VIDEO In the wall separating the cab from the passenger compartment, there is a closed niche in which the rear of the engine is located. In this niche, you need to carefully cut a hole and install a homemade hatch on it. Such tuning of the UAZ "loaf" body with your own hands will save you from having to dismantle the cylinder head every time you need to adjust the valves or replace their pushers.
The cars of the Ulyanovsk Automobile Plant were originally intended for military and national economic needs, therefore the undercarriage, frame and chassis were made of materials of increased strength. After the collapse of the Union, a lot of cars from state ownership migrated to the private sector, continuing to serve faithfully. True, the UAZ body requires some attention, systematic restoration of the paint layer and removal of corrosion.
Before starting the repair of the UAZ body, determine the degree of damage. Sometimes corrosion starts from the inside of the body, although the outer paint coat appears to be intact.
Wash and dry your vehicle thoroughly before scheduling repairs. Inspect the body for damage. Depending on the amount and size of corrosion, you decide whether it will be a DIY repair or send the car to a car service. Overhaul, or medium, is to be done.
So, you decided to repair the UAZ yourself.
You clean problem areas to a metallic sheen.
If the rust has eaten through the metal, you will have to put patches, weld them on the inside. Align the welding seams with an emery disc;
First, smooth out any dents on the metal;
Before applying the putty, wipe the body from dust, dry particles of old paint and then degrease.
Treat the car body with phosphating primer. This measure localizes the centers of corrosion, even if there are rust spots, and protects the metal from further oxidation. The protective primer is diluted with a solvent and applied in a thin layer from a spray gun.
After the phosphating primer, walk with an acrylic primer so that the phosphate does not chemically react with the putty.
Now proceed to puttying. Apply the filler in thin layers, smoothing out any unevenness in the metal left after mechanical repairs. The putty is applied at least three times with intermediate drying and sanding of each layer.
