How to make hydraulics on a UAZ 469 - auto magazine vikup-autoprofi.ru

Principle of operation

The whole structure works like this: when it is necessary to lift the body, the driver moves the valve to a position that ensures oil flow only in one direction and turns on the power to the pump drive. The pump takes oil from the tank and supplies it under pressure to the hydraulic cylinder. When the body is fully raised, the power to the pump drive is turned off. The crane will not allow the body to lower under its own weight, since it does not allow oil to return. The body is lowered by moving the valve to the oil reverse position, the pressure in the hydraulic cylinder drops and the oil flows back into the tank, and the body lowers down under its own weight. In the video, a self-made UAZ-3303 dump truck:

How to make it yourself

In order to equip a UAZ with a dump truck, it is necessary to prepare drawings.

You can lay a square beam under the front side of the car, attach a long cable to it, which needs to be wound around the entire body part. To unload, you need to open the side of the vehicle, pull out the cable and attach it to some support, for example, a tree or pole. After this, you should start the engine and start moving forward. Moving along the body, the wooden beam will pull the load together.

Another method is to install a hydraulic lifting mechanism, which consists of a half-frame, a hydraulic pump element equipped with an electric drive, a hydraulic crane, an oil tank, a hydraulic cylinder, and high-pressure lines.

Step-by-step instructions for making dumping equipment:

Useful tips

It is recommended to secure one end of the semi-frame with pin hinges on the loading platform, this will help facilitate the operation of the installation. The top of the cross member should be equipped with cross bars to provide support for the entire perimeter of the loading platform.

To connect the semi-frame body to the car, it is necessary to use a welding machine for greater structural reliability.

The hydraulic cylinder can also be taken from the GAZ-53, because it is long enough to tip the body part, and the ends have ball-type tips.

The subframe should be made in the form of a bracket. This shape will allow the hydraulic cylindrical element, when folded, not to interfere with the body tipping over and the installation of the upper part of the semi-frame on the lower one. Parameters and fasteners must be selected experimentally.

After connecting the pumping element lines to the electrical circuit, it is recommended to install hydraulic crane equipment. When the body is raised, it will facilitate the flow of oil fluid in one direction. When the valve turns, the oil will flow back into the tank.

During installation and manufacture of a dump truck installation, safety precautions must be observed. The vehicle must stand on a flat surface, and the wheel mechanisms must be secured with special locking devices. The car needs to be put on handbrake. When making parts, you should wear a protective mask and goggles.

Video “Features of installing an amplifier on a Loaf”

What points should be taken into account when carrying out installation work - see the video below (author - Andrey 68).

Good afternoon. I recently purchased a Loaf and am going to customize it a little for myself. The first thing I thought about after a trip of 600 km was the possibility of installing power steering or an electric amplifier. What are the budget options?

Throttle speed 66. The flight is normal. The pump is also from a shishiga, only the pulley is enlarged www.drive2.ru/l/8667980/

I have a steering gearbox from Sobol-Gazelle, I took the YB (ZF) pump as a kit, but you can assemble it yourself. There are options here, choose what you can find cheaper.

www.drive2.ru/l/6928499/, this is the final price and ordering site in the previous two, the most budget option. max 5 t.r.

Japankar, google it. The site provides spare parts from Japan. there is carbon and all the rest of the stuff. Look how I did it, I recommend satin.

The theme is like a torn button accordion with hundreds of options...

There are many loaves, and each power steering has its own. :))) www.drive2.ru/l/5989750/

You wrote me. He won't see your message. :)))

Yes. I understand, but he will go into the chat) if a person is interested, he will look not only by notifications)

Forget it in the drive search. I ordered it for myself in Vladik, I found the gearbox on the drome for 2.5 plus delivery, the Toyota steering column - I found it in the garage for free, the UAZ ZF Yubei power steering pump, standard mountings - about 5 t.r., a high-pressure hose - from a Euro 4 loaf, like 1, 5 t.r., tank, hoses, clamps -500r., and the work of a welder. I assembled the kit slowly over the winter, the column needs to be taken with cardan shafts - the Nissan-Toyota splines are the same, and Dextron immediately filled the system with semi-synthetic. True, I took the gearbox slightly wrong, but maybe I’ll change it later. You can look at my page.

Classic - UAZ “loaf”

Examples have been given more than once when the most difficult tasks in Russian regions were handled exclusively by vehicles of the UAZ 452 type. It’s not every day that you can use a heavy-duty URAL or an expensive foreign-made SUV. But for UAZ, the issue of modernizing the existing design is relevant. Because, despite the excellent maneuverability, the ease of control for the driver is not always at the desired level.

One of the elements that makes driving this off-road van much easier is the power steering (power steering). The use of hydraulic booster on the UAZ “loaf” began relatively recently. But before you start tuning, you need to remember the structure of the standard factory steering design.

“UAZ Profi”: truck crane, dump truck, tower and other unusual versions of Ulyanovsk SUVs

This sometimes happens - a car plant invites you to inspect not its products, but the add-ons installed on its cars. The Ulyanovsk Automobile Plant showed a van, a refrigerator, a hydraulic lift, a platform with a hydraulic lift, and even a dump truck. And all this, as well as much more, is based on the UAZ Profi family.

It was almost a fairy-tale plot, but in reverse: hut, hut, stand with your front to the forest and your back to me - I told myself, looking at the line of cars lined up in front not with cabs, but with bodies, vans and all the other installed goods. A sort of review of the basis and superstructures, if you remember historical materialism from your institute days. And there was something to look at - the factory workers showed the entire serial range of add-ons produced on the basis of the “Pro” family. Both our own production and from third-party authors.

An onboard platform with a CMU is one of the trends in the modern commercial automotive industry.
The UAZ Pro family appeared in 2022 and almost immediately showed a good start.
Single- and double-row cabs, rear- and all-wheel drive - good potential for expanding the range of add-ons. In addition, UAZ had to move, since the niche of banal tilt LCVs was tightly occupied by another Russian manufacturer of light trucks. "Tadpole" is a dump truck.
Unloading on three sides will not work for safety reasons. First, about what the plant itself does: flatbed platforms, manufactured goods vans, refrigerators. The big advantage of such machines is that they can be supplied with either a gasoline engine or the ability to run on gas. It is known that gas equipment installed somewhere on the side does not always work correctly, and questions arise with warranty, maintenance, etc.

A promising dump truck on the Profi chassis will hit the market early next year.
A van from UAZ is not just an average box, but an opportunity to choose components during its manufacture.
As a standard, the outer frame of the van is surrounded by corners made of aluminum alloy. In “Optimum” this will already be a galvanized semicircular corner with a coating. It's the same with seals. In the standard it is rubber-plastic, in “Comfort” it is polymer. Even the internal volume can vary: 10.8 and 11.3 m3. If a client orders an “Optimum” van, then the warranty period for the superstructure is 4 years or 150 thousand km. Solid. The refrigerator uses a Nizhny Novgorod refrigeration unit. The bread truck from TTM Center is designed for 112 trays of bakery products.
Trays can be plastic or wooden. Naturally, the plant does not provide its chassis to everyone, but after a comprehensive assessment of the technological and financial potential of the superstructure manufacturer. It just so happens that most of them are located not far from Ulyanovsk, 400 kilometers away.

The location of the gas cylinder is across the frame for flatbed platforms, along the frame for vans.
Perhaps the most interesting car, as well as technically rich, was the auto hydraulic lift from. The base is the five-seater “Pro” version, all-wheel drive. Behind the cabin, on a special subframe, there is a lever-hydraulic installation of the AGP-15 RT lift. Working height - 14.2 m, reach - over 5 m. Electrical insulation of the working platform - 1000 V. Lifting equipment is Italian, the control panel is located on the installation, with dubbing in the basket. The advantages of this arrangement are the minimum space occupied by the machine during operation. The downside is that the lift is cranked, not telescopic. It provides slightly fewer possibilities than the telescopic one - in order to “craw” close to the object, you will have to try. However, machines with such units are convenient not only in dense urban areas, but also anywhere where the work front is not so high.

The control panel for the refrigeration unit of the refrigerator is located in the cabin.
Sets the operating temperature from -20 to +10 °C. Another interesting new product from Ruskomtrans is “Profi” with an on-board platform and CMU.
The sides are aluminum, the machine has two hydraulic support struts for loading/unloading. At a maximum boom reach of 4 m, 350 kg of cargo can be hung. The “goose” electric hydraulic station of the Italian company Maxilift is powered from the vehicle’s on-board network. Platform dimensions 3200x2100 mm. By the way, the “Profi” with the CMU framed in aluminum looks very stylish - in our country they are greeted by their clothes. Automotive hydraulic lift on the UAZ Profi chassis.
The Profi family was aimed at private business from birth, therefore the appearance of this model was predetermined in advance. Moreover, there is such a vehicle based on the previous UAZ-3303 - a small all-wheel drive dump truck. Development initiator – . The tadpole-based dump truck is no slouch—the platform is reinforced with 1.5 mm thick sheet steel. Load capacity - 800 kg. The machine will certainly be in demand among small construction firms and small companies delivering soil, peat and other gardening products. If you examine the platform at the attachment points, the idea of three-way unloading is clearly visible, but so far the body can only rise in one plane. Considering that the current family of UAZ vehicles looks more attractive for work, the manufacturer of the tipper platform add-on installed it on the Profi. The carrying capacity is greater: one hundred kg, the body dimensions are larger - 3090x2060 mm. Side height - 400 mm. There are no additional reinforcing elements at the base of the dump truck; factory engineers are confident in the reliability of the Profi chassis. In the transport position, the platform is additionally fixed. The body lift is controlled from a remote control. Add to this set all-wheel drive, driver airbag, ABS and EBD, and the result is a good 4x4 dump truck. True, you shouldn’t look for it right now at dealers; the car has not yet been certified. The first production samples will appear early next year.

A promising van from Kolomna Mechanical.
It looks at the level of Western models, but what it will be like in practice is the question. Another interesting machine seemed to me to be the “Pro” version with the superstructure of the Kolomna Experimental Mechanical Plant.
This van will certainly appeal to the Ministry of Emergency Situations, rescuers and other emergency services. The crew is located in a five-seater cabin. Accessible from three sides, the spacious fiberglass van offers plenty of storage space for useful equipment, tools and spare parts. So far there is only one question for the add-on - how will the plastic behave when working at low temperatures? Ideally, the creators of the machine see it in service with public utilities, emergency gas services, electrical networks, etc., that is, the main emphasis is on future consumers who are tied to government supplies, based on one main indicator - price. However, there is no real price tag for the car yet. A convenience store from TTM Center. If necessary, it can be easily transformed into a solid van.

Remote control panel for lifting the dump truck.
The cable cord is long, it is convenient to control the unloading. Naturally, given the all-wheel drive chassis of the UAZ, most of the add-ons are designed to work on bad roads in rural areas or without them at all: a grain van, a mobile home, a car shop and much more. Similar cars can also be ordered in a 4x2 version, but, I repeat, this niche is already occupied by another car plant, which does not prevent Ulyanovsk residents from competing for a place in the market. The main competitor, GAZ trucks, also have five-seat versions, but there is only one door for the second row. The “Pro” version with a five-seater cabin looks more mobile or something. Most vehicles with UAZ add-ons promise to be serviced in one place and at the same time as the chassis, or a time interval close to it. But this is very good, at the level of foreign automakers. In general, the plant made its proposal. Now it's up to the market.

Examination

With the engine warm and running, turn the steering wheel from side to side. In the first seconds, excess air should come out of the tank. If it starts to foam, it means the system is leaking and you need to look for a breakdown. After thoroughly sealing all the hoses, start the engine and check the operation of the amplifier again. The power steering installed on the UAZ “Bukhanka” from a foreign car should operate smoothly and silently. The belt does not whistle, there are no leaks of working fluid.

You will immediately feel the performance of this amplifier. The steering wheel turns much easier than before. During operation, regularly monitor the remaining liquid in the plastic tank. It needs to be topped up if necessary. Operating the hydraulic booster when the fluid level is insufficient can result in pump failure. The steering wheel will become much heavier.

Do-it-yourself installation of power steering on a UAZ-469

Recently, almost every manufacturer equips their cars with power steering. It can be either hydraulic or electric. The latter type is actively used on domestic Kalinas of the first and second generations. On Ulyanovsk cars, they use a classic hydraulic power amplifier. But many people ask the question: why not install power steering on UAZ of other models? Indeed, there are many cars that are still not equipped with such an option. These are the “Loaf” and the 469th UAZ, popularly called the “Kozlik”. In today's article we will look at how to do it yourself.

Step-by-step instruction

The hydraulic lift required for upgrading a UAZ-3303 car with your own hands consists of a supporting semi-frame, a subframe, a hydraulic pump, a control valve, an oil tank, a hydraulic cylinder and an oil system.

Remaking the half frame, hydraulic cylinder and subframe

The semi-frame is necessary to fix the body and change its position. It consists of two parts: the first is firmly attached to the frame of the vehicle, the second to the loading platform. Pin hinges connect the elements to each other. In such a design, it is advisable to use I-beams or T-beams.

The top of the semi-frame is reinforced with a crossbar and side protrusions to support the body; only crossbars are installed at the bottom. At the locations of the pin hinges, special holes are made to ensure reliable fixation of the fasteners.

The half-frame base can also be held together by welding and bolting at the bottom.

Sound insulation and interior insulation

For noise insulation and insulation of the interior, you will need approximately 5 m2, that is, 11 sheets of self-adhesive vibration - 50 * 100 cm with thin aluminum, one might say, this is an imitation of foil. To save money, it is better to buy it at the market than at a car dealership. It is necessary to muffle extraneous sounds in the car, the main thing is to never glue it to rust, then all the work will go down the drain.

Before this, degrease the areas to be glued with acetone; do not glue the entire sheets because of their rigidity, but in parts.

Remove the protective film and press tightly. To insulate the floor, you can put bitumen - corrugated foil, bitumen base and protective film.

We also remove the film and, using a 2 kW hair dryer, heat the sheet itself and apply it in small parts; it fits perfectly on uneven surfaces. In areas with large transitions, slopes and edges, we take two sheets for this.

We cut it, heat it more strongly so that the bitumen comes out, apply it in halves and press down. The most difficult part is the front part under the driver's seat, there should be a whiplash from all sides. We also lay it out, start from the steering wheel, remove the protective film, pull it under the bottom and heat it in pieces, also press down and remove the paper completely.

We push the credenza, in the places of the holes, here we bend the sheet, press it, look on the other side how it fits, mark it for the cutout and use a through screwdriver to pierce these marks, and on the back side they are clearly visible, put a screwdriver in place of the hole and punch it with a hammer, so they not covered with a sealed film.

Repair and replacement of the pivot assembly

Lubricating the UAZ kingpin

Repairs of cars such as UAZ are best carried out at car dealerships. Experienced professionals will adjust all components of the king pin and troubleshoot other parts without any problems. But some car enthusiasts can perfectly repair a car without outside help.

Repair or replacement of kingpins on a UAZ Patriot takes place in several stages:

prepare the tools necessary to remove the bushing;
put the car on the handbrake, it is recommended to support the car from behind and lift it with a jack, remove the wheel from the front;
remove the fist from the turn;
Unscrew the washer with the appropriate key, remove the interfering parts;
remove the clamp bushings;
remove the king pins;
remove the supports from the balls using the necessary tool;
return everything to its place;
apply a special gel.

By following these steps, you can make the repair yourself. Conventional UAZ 469 kingpins are capable of operating without breaking for a very long time, if the car owner follows the necessary operating requirements and recommendations for self-disassembly of the necessary elements and repairs.

Replacement is carried out in the following sequence:

drain the oil, hang the axle, chock the wheels;
unscrew the caliper responsible for the brake;
remove the brake shield;
remove the steering wheel ends;
remove the kingpins and gel valves from above and below;
wash the king pin that was just removed;
wash all removed components and inspect them;
Lubricate the bushings and compress them;
remove chips from the spiral channel;
change the semi-axial seals, if necessary;
make sure that the kingpin is working;
return the oilers and pivot caps to their places;
install cords;
After repair, put everything back.

Description of power steering

Purpose and design

Hydraulic cylinder. This element is used to facilitate the rotation of the wheels when the steering wheel is rotated, this is carried out as a result of the pressure of the consumable material.
Pumping device. With the help of this component, the optimal pressure parameter in the amplifier is maintained. In addition, the pump allows oil to circulate through the hoses.
Distribution mechanism. As the name suggests, the component is used to distribute fluid flows into the corresponding cavities.
Hoses and pipes. Through the system pipes, the working fluid is transferred from the tank to the pump, as well as between the main elements of the unit.
The reservoir itself where the substance is contained. It should be noted that the reservoir may have a filter, as well as a dipstick, which will allow you to monitor the oil level in the reservoir.

Operating principle

As for the principle of operation, it consists in moving the spool while rotating the steering wheel. This element moves throughout the system, which helps open the drain tubes. When the pipe opens, the substance under pressure passes into one or another cavity, thereby affecting the piston element, which, in turn, facilitates the rotation of the wheels (the author of the video is the Demian0805 channel).

Operating principle of the design

The installed equipment on a homemade dump truck works like this:

If it is necessary to raise the body, the car owner turns the control valve so that the oil is supplied in one direction.
After this, the driver turns on the power to the pump drive.
The pressure pump system supplies working fluid to the hydraulic motor.
After the body is completely raised, the pump is turned off.
In this process, an important role is played by the valve, which does not allow oil to flow back, so the body does not fall under its own weight.
The controlled platform takes its initial position during the return movement of the working fluid, when the pressure in the hydraulic cylinder decreases.

Power steering on AUZ 469

Hydraulic amplifiers operate from fluid pressure on drive units. The pressure is created by a pump that operates through a belt drive from the engine crankshaft pulley. Hydraulic power steering requires an extended belt and modification of the pulley. Therefore, the old drive belt, fan impeller, and crankshaft pulley must be removed.

The fluid pump is unscrewed and the radiator impeller is secured to the wheel hub. For further operations, you need extended bolts for the power steering and a spacer, which is included in the kit. The long belt is pulled onto the new pulley. The fuel filter bracket is removed. The power steering pump for the UAZ 469 will be installed here. The price of the UAZ hydraulic booster in Moscow ranges from 15 to 40 thousand rubles.

The power steering kit includes a bracket. It must be installed in place of the pump stud. Secure the bracket and pump bar to the locknut. After installing the belt, you should adjust the correct tension. To maintain it, there is a special tension roller used in the design of many cars.

Correct adjustment of the power steering drive belt is carried out as follows. When pressed with a finger, its deflection should be 10-15 mm. The belt should rotate at an angle of 90° relative to the plane of the pulley. The fuel filter is placed in its regular place, in a square hole.

To install the oil tank, you need to drill two holes in the left engine mudguard using a drill.

We use nuts, bolts, and a clamp prepared in advance to install the oil reservoir. The tank is connected to the pump using a polymer hose. Transmission oil is poured into the system. Once again, you should check that all parts are installed correctly and you can start the car.

Installation of the pump and reservoir

Any hydraulic booster is driven by fluid pressure. To create it, there is a pump. But it works through a belt drive - from the crankshaft pulley. It is worth noting that there are different belts - for power steering on UAZ and for cars without it. We will need a longer element - for the hydraulic power steering. So, remove the drive belt, fan impeller and crankshaft pulley.

What will we need to buy?

To do this, we need to purchase a power steering column, as well as a pump. The latter will create and maintain the necessary pressure in the control system. The operation of the element is carried out by a drive belt. We will also need a fluid storage tank and connecting hoses. The latter are divided into two types - low and high pressure. The first will drive “return” into the tank, and the second serves to circulate liquid in the system itself. As for the amount of liquid that is used in the system, it is not too much. For UAZ, 1.2 liters of special oil is enough. It differs from motor oil in viscosity and consistency.

Tractor based on UAZ 469 - assembly procedure

An important role in the process of personally assembling a homemade tractor from an existing UAZ SUV is played by the correct sequence of actions of the manufacturer.

The work algorithm should look like this:

First you need to assemble a rectangular vibration-resistant metal frame. Metal pipes with a diameter of 57 mm each are suitable for this. They will play the role of spars and traverse. Parts must be secured by welding;
Next, you need to install the steering column used, which can also be taken from the UAZ in advance. It is best to mount it on the right side - in this case, it will be much easier for the manufacturer to install the steering mechanism assembly with the drive. To install the mechanism, you must first remove the lever and place it on the splines. To assemble a metal rod, the manufacturer will need a working gas-electric welding machine;
Next, you need to equip a homemade UAZ 469 running tractor. First, you will need to correctly install the standard rear axle. To do this, you need to cut a flange on the existing long axle shaft and carefully drill a hole in its very center. The resulting segment will need to be processed and inserted into the hole. The outer part of the workpiece must be scalded and the resulting excess parts must be cut off. After this, you will need to shorten the long stocking you are using. To do this, you can use two short axle shafts. In the area where the standard stocking is cut, you need to carefully remove the chamfer and weld the resulting joint. In the place where the weld is formed, you will need to install a caliper that will reliably protect the factory shank from impact. Next, the assembled frame can be equipped with ready-made UAZ axles, having previously used a prepared V-shaped structure for this purpose. At the same time, it should fit tightly on the standard cushions built into the rear axle;
Then the homemade tractor from the UAZ SUV will need to be equipped with a brake system. To do this, the agricultural machine must be equipped with the existing brake master cylinder from a Russian SUV. In addition to this, you can install a steering gear, a standard linkage and a factory column on your homemade product. To more securely fix the gearbox, you need to prepare in advance a strong crossbar, previously welded into a homemade structure;
After this, the manufacturer can begin assembling the tractor transmission. After installing the motor, you need to install the gearbox and clutch basket. The moving parts of the mechanism must be secured in such a way that during operation they do not interfere with each other’s movement;
Then you can dismantle the old seat from a UAZ SUV and install it on the frame using a spring;
At the end, the UAZ tractor will need to be painted. To do this, metal parts need to be treated with putty. After it dries, you will need to apply 2 layers of paint alternately to the frame and body of the tractor - this will protect the homemade product from corrosion. The video will tell you more about the self-assembly of a homemade tractor from a UAZ SUV.

After the last layer of paint has dried, the UAZ tractor will need to be tested. First you need to test the chassis of the agricultural machine. To do this, you need to drive the unit on a flat road, and then on rough terrain. If at the same time no creaks or other extraneous sounds are heard from the chassis, then you can proceed to testing the homemade product in the garden. A finished UAZ tractor can be equipped with various mounted implements. To do this, you can use a plow, cutters, hillers, potato diggers and a trailer. The main thing is that the weight of the equipment does not exceed the traction characteristics of the engine. Otherwise, the motor will constantly overheat and succumb to increased wear.

Characteristic

At the moment, almost all budget cars are equipped with such an amplifier. However, owners of old cars have a desire to retrofit their car with power steering. This is a very useful option. Even with a large diameter steering wheel, the effort required to control the car will be several times less. This is especially noticeable when parking in densely populated cities. The power steering itself is part of the car's steering system and runs on hydraulic fluid pumped by a pump. This also includes the steering column. The usual factory one does not fit here. There are many advantages of this system.

The first is the comfort of control, because you no longer need to turn the steering wheel as much as before. The second is reliability. The hydraulic booster practically does not fail. The third advantage is ease of maintenance. You will not have any difficulties when operating such a car. Even if the amplifier breaks, you can fix it with your own hands. Moreover, it is quite possible to get to the garage with such a breakdown. The only thing that will happen is that the ease of control will deteriorate. The steering wheel will become “heavy”. By the way, for the first time such an amplifier was installed on Gorky’s “Chaika”. GAZ-13 was the first car with power steering.

Specifications

The UAZ Profi dump truck has a simple design and ease of operation. This transport is designed to work in any climatic conditions and on any terrain. All the main elements of the car are mounted on a welded support frame, which is made of high-strength steel. This unit can be repaired in the field; all components and mechanisms are easily accessible.

It has an 8-cylinder gasoline engine, manufactured in accordance with the international environmental standard Euro-1, and a manual 5-speed gearbox. Brakes are disc, dry, equipped with a mechanical drive.

Transmission ratios:

The gearbox is equipped with 2 cardan shafts, which are connected to the drive axles of the vehicle. The intermediate shaft is located between the manual transmission and the transfer case. The front and rear axles have a single bevel type final drive with spiral teeth.

UAZ 3303 Ural rascal › Logbook › Hydraulics

Hello everyone! It’s finally happened - I assembled full-fledged hydraulics for the tadpole. Everything is of a classic design: reservoir, pump, hydraulic distributor, cylinder. Everything works great! I'll write everything down in more detail.

1. Pump. Replaced the NSh-10 right rotation www.drive2.ru/l/4517398/. (I’ll get ahead of myself - the pump needs to be changed, because the one loaded with hot oil does not want to unload). It’s comfortable, I can screw on the hoses without any problems. Doesn't interfere with anything. I was most worried that the belt would slip; after all, the pulley on the drive is a B profile. But so far everything is ok. In principle, you can install a short crankshaft-pump belt, then the contact area of the belt will be the floor of the pulley, most likely I will do so.

2. Hydraulic distributor. In the stash there was a tractor hydraulic distributor R-80 with YuMZ-6l.

It has three sections. One for the dump truck, the other two will power the front and rear hydraulic winches (although they don’t exist yet, we’ll come up with them). Initially, I wanted to install the distributor in the cabin, on the tunnel between the gear shift knobs. But he assumed that if something happened, there would be a viper in the cabin in the form of splashed oil. And my ceiling is white...). Then I installed a hydraulic distributor in the tunnel on the cabin side member. To do this, I welded two sections of 20/20 square pipe onto the spar and secured the spreader.

Then I made a cut on top of the cabin and made a power handle from some kind of rod.

3. Tank. I decided earlier on where to mount the tank - on the cab, at the back. After a short search, a 12 liter round tank was found at a scrap metal collection point. I don’t know what unit it comes from. But inside it was a solarium. Didn't wash it much. I cut in a ball valve and welded a fitting for the return line.

4. Lifting cylinder. Initially I was looking for a double-sided cylinder to lift the body. I really wanted a forced lowering of the body. For this purpose, I found (at the same collection point) the working cylinder of the DT-75 blade, and in place with fasteners, which made it easier for me to install it. The cylinder stroke is one meter.

After several fittings (about 15 times), I made fastenings in the subframe and in the base of the body from 100 channels. The cylinder is tilted at 30 degrees.

What is the load capacity? Is COM standard or homemade? Is the PTO installed in the transfer case with NSh-10?

Sorry for the long silence - I was sick. Load capacity 1000 kg. The lump was specially developed (with forced lubrication). Placed on the distributor.

When driving, can you turn it off and then turn it on? Who is installed instead of the top cover of the transfer case?

The elevation angle is too small. What should you do if what you were transporting stuck to the body and won’t slide off?

Cylinder on ball joints Ф50mm. And this is more of a construction option. For peasants there is a slightly different model - with side unloading. For the distributor in the cabin, I can duplicate it with buttons (install an electric valve). But no one has canceled the FSA yet

Hydraulics on UAZ

I understand that it is bad form to proliferate topics, but I would like to know the opinion of hydraulics specialists in relation to our topic (drilling).

". I found out: 1. The PTO (power take-off) is designed for installation on a UAZ DUMP TRUCK (. ) paired with an NSh-10 (. ) hydraulic pump with a maximum pressure of 25 atm. and productivity 22.5 l/m; 2. estimated output power 1.33 l. With.; 3. activated by setting the transfer case to neutral and the gearbox to reverse; 4. maximum operating time under load - 30 seconds. This same PTO is designed in such a way that it only works in the “neutral” position of the transfer case. The bearings are ordinary, without lubricant. Maybe it will live longer, but the manufacturer guarantees 30 seconds. "

— This is from the UAZ website. It looks like the plant and its engineers are busy with something VERY important, but not at all what the people who drive these UAZs need. There are homemade products, and even with photos (attached), however, without comments from the authors. But the fact is that UAZ drivers don’t need anything more than a winch. But SOMETIMES I want to use the UAZ chassis engine for drilling with augers. with all the ensuing consequences.

If anyone has thoughts and experience on this topic, can you share?

The idea is simple. Belt from crankshaft pulley to pump. The NSh10 with the entire bracket and pump for the steering wheel is installed on the old MAZ; the new MAZ already has the NSh 32 with a double-groove pulley. Find and place. The profile B belt seems to transmit up to 10 horses. I posted the data somewhere. Well, or if the radiator allows it (on a UAZ it should), resharpen the pulley, put a cardan into the end of it and a pump from it. I did this at my rig, although I also installed a gearbox with a disconnectable clutch for the pump.

My Unimog has a standard hydraulic pump for the hydraulic system, also with a belt drive, the pump already has a relief bearing inside and large-diameter, single-groove pulleys. One more for the helmsman.

Never say never"

I had the opportunity to work for three months as a car mechanic at a UAZ center, during which time I changed the bearings on the transfer case twice, and the bearing on the rear axle drive shank jammed. The reason is simple, long-term driving with the ratchet switches off on the front axle, anyone who knows how the transfer case works on an UAZ will understand. The transfer case is positioned at an angle, the front axle drive shaft is at the very bottom, the oil level in the transfer case is hidden only by the front axle shaft, that is, if the front axle drive gear does not rotate, the oil does not splash and the transfer case is not lubricated. Similarly, when the PTO is operating, the transfer case is not lubricated.

It was also noticed when driving with the ratchets turned off that the spline on the front driveshaft wears out a lot.

Model 33036

At the beginning of the 2000s, the car plant in Ulyanovsk began producing modifications of the on-board vehicle, installing other, modified cabins on its extended chassis, which were supposed to increase comfort for the driver and passengers. Thus, the UAZ-39095 model was created.

Important! The main difference between modification 39095 and the base one was the cabin with a sleeping bag.

Its dimensions were increased, which made it possible to install a folding bunk behind the seats and equip a trunk.

The inside of the cabin was upholstered with sound-proofing material, adjustable seats were installed and the instrument panel was improved.

Due to the increase in the size of the cabin, the body was slightly reduced, and its load capacity was reduced to one ton.

The cargo platform was equipped with an awning with folding canopies.

This awning can be adjusted in height. The body was equipped with seats for four people and a tool box.

A so-called “kenguryatnik” was mounted above the front bumper - mechanical protection made of bent pipes.

A double cab with three doors was installed on the 3303 chassis. Now the number of people accommodated in the cabin has increased to five.

All seats are soft, and the front ones are adjustable. The cabin has fairly good sound insulation.

The enhanced heater completely ensures a comfortable temperature for people in the cabin in cold weather.

Additional heating is provided by the engine, above which the cabin is located. The roof is equipped with a hatch for interior ventilation.

Due to the fact that the wheelbase of the vehicle has been slightly increased, the load capacity remains quite high - 1,100 kg.

The geometric dimensions were 4,847x1,974x2,355 mm. The cargo onboard platform is made of metal.

All sides recline. The installed awning can be adjusted in height.

A powerful engine (shown in the photo on the left) with good technical characteristics produced by the Zavolzhsky Motor Plant, which produces 112 hp, is mounted on the on-board vehicle of this modification of the UAZ-3303. With. with an average fuel consumption of 10.5 liters per 100 km.

The UAZ-33031 model differs from the basic one in the presence of shielded electrical equipment.

Typically, such modifications are made for the needs of the Armed Forces. However, such cars can also be useful for the national economy.

For example, during the construction of powerful power lines or during the maintenance of nuclear reactors for various purposes.

For export, this model was manufactured in two modifications:

“330316” – for the needs of countries with a temperate climate;
“330317” – for export to countries with a tropical climate.

The “33032” model was designed and put into mass production at the plant. This is a car adapted for driving on liquefied gas.

All machines of this modification were equipped with gas equipment for normal operation in working conditions.

UAZ has mastered serial production of an isothermal van based on the “3303” model. This van was named "2746".

A panel-type body was placed on a long-wheelbase chassis behind the double cab.

His back door had double doors:

the dimensions of the car were 4,544x1,924x2,540 mm;
body dimensions inside - 2,586x1,538x1,810 mm;
the floor inside the body had an area of 4.7 square meters. m;
internal body volume - 7.22 cubic meters. m;
The carrying capacity of the isothermal van is 1,100 kg.

Based on the “33036”, a modification with a lifting tailgate named “29232” was produced.

It had a metal body with an awning and four seats at the front side. The chassis had a long wheelbase, and the ground clearance was lowered to 195 mm.

The Saransk Automobile Plant produced the UAZ-2923 model based on the “33036”. Instead of a flatbed body, a dump metal platform was installed on the vehicle.

Popular manufacturing options

The UAZ-3303 truck has a two-seater solid metal cabin with two side single-leaf doors. In the front part of the structure, under the removable hood cover, the engine is located. Behind the cabin there is a cargo platform with folding sides. Depending on the model, it is made of wood or metal. The body can transport cargo weighing up to 1200 kg.

Dimensions of UAZ –3303

The technical characteristics of the car are designed for operation in different conditions, including in rural areas. Many people working in the agricultural sector note that despite all the advantages of the truck, it does not have equipment for unloading materials using a dump truck. However, it is possible to solve this problem if you construct a dump truck from an UAZ with your own hands.

Re-equipping a vehicle with a lifting mechanism will increase its functionality and save time on unloading the body. At the same time, the carrying capacity of the vehicle remains at the same level.

There are two options for making a dump truck convenient for use from a UAZ-3303.

Option #1

The easiest way is to lay a square beam under the front side of the body and attach a long cable to it, laid along the entire length of the platform. In this case, the truck will be unloaded as follows:

When opening the side of the machine, the cable is pulled out and attached to some stable support, for example, a tree or pole.
As the car moves forward, the beam moves along the body and pulls the load.

This method, although simple, is far from perfect, since the load may end up in an unstable position.

Option No. 2

When constructing a dump truck yourself, a more reliable way is to install the hydraulic system on the platform frame. Despite the fact that some companies offer ready-made kits for lifting the body, you can make such a device yourself.

DIY dump truck UAZ-3303

UAZ-3303 is a small truck with good all-terrain qualities due to the presence of all-wheel drive. It has a frame structure, with a cabin installed on it, under which the engine is located, and two boxes - a transfer case and a gearbox. Behind the cabin there is a cargo hog platform that allows you to transport up to 1200 kg of payload.

This vehicle has become quite popular in agriculture, but its owners complain about the lack of equipment for dump unloading, since the manufacturer of this vehicle does not equip it with such equipment. Owners often do not agree with this decision of the plant and remake the UAZ-3303 with their own hands, creating a dump truck on its basis.

Those owners who have converted their cars indicate a significant increase in functionality and a decrease in the time for unloading the body from cargo. At the same time, the carrying capacity of the car itself does not decrease, since it is not very high anyway. But the installed lifting equipment makes the driver’s life easier, especially if the car is used to transport work loads.
