Technical tuning

Do-it-yourself overhaul of the UAZ-3303 should begin with modification of the frame. During the tuning process, many different options are installed on the car, which leads to an increase in the load on the chassis. To prevent breakage, permanent pipes or metal plates are welded to the factory seams. If possible, reinforcement is carried out on all sides of the joints. After strengthening the foundation, you can begin to further improve the machine.

Wheel part

Installing alloy wheels improves the appearance of the car. The width and diameter of the rubber are selected based on the conditions in which it is planned to be used. If the car is transformed into an SUV for hunting and fishing, it is advisable to install wide wheels with the ability to adjust the pressure from the passenger compartment.

Installing wheels of larger diameter involves trimming the arches, lifting work to assemble the steering column rods, transfer case and gearbox. But the effort and resources spent are justified: the car gains greater ability to cross the country.

You can improve the off-road qualities of a car by installing tracks on the rear axle. Snowmobile tracks and gears are used to make them.

Chassis

Since the vehicle has been converted for off-road driving, the engine and transmission must be protected from mechanical stress. To do this, an aluminum or titanium plate one centimeter thick is fixed under the power plant.

If the springs are in satisfactory condition, they can be left, having been cleaned of dirt and rust. It is recommended to replace worn products. Hydraulic shock absorbers with height adjustment are installed on both axles. This will allow you to change the vehicle's ride height for on-road or off-road driving. A self-locking differential on the rear axle shaft increases the vehicle's cross-country ability.

Fuel tank

The fuel tank is practically not protected from external influences. When driving over rough terrain or bad roads, there is always a risk of not only puncturing the tank, but also completely losing it in contact with a stone, tree trunk or thick mud.

There are the following options for protecting the fuel tank:

Replacing standard fasteners with powerful steel ones with a thick steel plate on the base.
Moving the tank onto the loading platform or into the space between the cabin and the hold.

Both options are technically simple and do not require approval from the traffic police.

Step-by-step instruction

The hydraulic lifting mechanism that the UAZ will be equipped with consists of several components: a semi-frame, a subframe, an electrically driven hydraulic pump, a hydraulic crane, an oil tank, a hydraulic cylinder and high-pressure oil lines.

Half frame, subframe, hydraulic cylinder

Let's start with the half frame, it is needed to install the body. It is this that allows the body to tip over.

The half-frame consists of two parts. One part is rigidly fixed to the UAZ frame. By means of pin hinges on one side it is connected to the second part, to which the loading platform is attached.

It is better to make the longitudinal beams of both half-frames from T-beams and I-beams, and position them so that the upper part of the folded beams rests on the beams of the lower part of the half-frame.

The lower part of the semi-frame is strengthened with cross members. The top one, in addition to the crossbars, should also have transverse projections on the sides, which will provide support for the cargo platform along its entire width.

At the end where the pin hinges will be located, lugs are attached to the parts of the semi-frames, which must match with their holes. The pins will need to be installed in these holes, and they will need to be secured in the holes to prevent them from falling out.

To connect the half-frame structure, you can use welded joints, but it is better to secure the lower part of the half-frame to the car frame using bolted connections.

The second ball joint is the lower one, fixed to the subframe. This subframe should be in the shape of a bracket. This shape is made so that the hydraulic cylinder, when folded, does not interfere with the complete lowering of the body and the landing of the upper part of the semi-frame on the lower part. The dimensions and method of fastening the hydraulic cylinder subframe are selected experimentally. After this, the hydraulic cylinder is installed in place.

Hydraulic pump, its drive and control valve

Next we move on to the hydraulic pump and its drive.
Most often, the pump is NSh-10, from MTZ-80. Its performance is quite sufficient for the operation of a hydraulic cylinder. There are several pump drives, so we will describe the simplest one, namely from the starter. To do this, a starter from MTZ-80 is taken and slightly modified to allow operation for a long time. Next you need to connect the starter shaft to the pump shaft. To do this, you can use the hinge from the steering of any passenger car. Next, the starter and pump are fixed on the platform to prevent them from moving relative to each other.

The pump and drive are fixed to the cross member of the car frame, so as to prevent their damage. Then the wiring is thrown from the car’s battery to the starter, making sure to include a switch in the circuit.

An oil tank is also attached to the frame of the car; a volume of 10 liters will be enough. Then the lines are connected from the oil tank to the pump, and from it to the hydraulic cylinder.

History of UAZ 3303

All-terrain vehicle - produced by the Ulyanovsk Automobile Plant since 1985. The new car replaced the UAZ 452D.

The 3303rd has been released to date. There are two modern modifications.

The truck cab is all-metal. Two people can comfortably fit inside. The car is equipped with single-leaf side doors and a removable engine compartment hood. Platform 3303 can be different, depending on the modification: made of wood or metal.

Regarding the changes, I would like to give a more detailed description:

Version 3303 is often called a passenger car. These small, light commercial models were designed to transport various agricultural products, such as milk.
The dashboard platform and two-seater cabin are the classic “calling card” of the UAZ 330394;
The next modification is distinguished by an already enlarged step. In this case, the platform may consist of boards or metal;

The range of engines installed on the UAZ 3303 is, as a rule, limited to two gasoline power plants with a volume of 2.4 and 2.8 liters.

Metal body 3303

The first UAZ 3303 is an all-wheel drive vehicle, proven over the years and on national roads, which can easily deliver various loads on any type of road and even completely off-road. Incredible maneuverability, extraordinary simplicity, ease of maintenance - all this applies to this machine.

Note. Experts say that the strength of the UAZ is its ability to transport cargo whose weight is several times greater than the weight stated in the technical data. In this sense, the car is even compared to an ant.

Designer tuning

Modernization of the car's exterior is carried out in order to distinguish it from the general monotony, make it noticeable and eye-catching, and attract the attention of others. Proper tuning can not only visually improve the appearance of the car, but also make it more comfortable and functional. Irrational modernization leads to accelerated wear of components and mechanisms, reducing the service life of the vehicle.

Interior trim

As for the UAZ-3303, tuning the cabin is an almost unlimited field of activity. You should start from the outside.

You can do the following:

make elegant footrests.
restore old optics by inserting new LED lamps into them;
install tinted windows, equip doors with electric lifts;
covering with plastic fairings;
paint it in a color that matches the purpose of the machine;

Interior improvement options:

lightweight plastic cabinet with sliding doors.
air conditioning system;
ergonomic steering wheel with adjustable column;
seats with air suspension, armrests and position controls;
on-board computer with navigator;
covering surfaces with soundproofing and heat-insulating materials;
safe and multifunctional dashboard;

A removable console can be installed on the engine compartment lid.

Bumper

The best option for remaking the bumper is to install a powerful steel grille. This product will give your car a new look and protect the radiator from stones and branches. In addition, the thick tubes provide a good base for the main headlights and exterior fog lights. The rear bumper is turned into a monolithic structure, which serves as a step for lifting into the body.

If the bumper should not come into contact with obstacles, it can be covered with foam rubber and covered on top with fiberglass impregnated with epoxy glue.

Interior decoration

Cabin tuning is an unlimited field of activity where you can realize any ideas. Inspired by photos from the Internet, let's get started:

Get rid of the old upholstery and also remove the mirrors.
Select the material and take measurements.
Upholstery the interior with your chosen fabric. Please learn that soft material should be laid between the fabric and the roof of the UAZ - for example, padding polyester.
Select the shape of the seats and adjust them by trimming the edges (if the seats are not spacious enough).
Weld small corners with holes to the seats.
Screw the chairs into the floor using bolts.

By moving the seats forward, you can sit back in them. Accordingly, there will be less stress on your arms and back.

If you wish, you can restore old optics, install tinted windows or electric lifts, trim the interior with plastic fairings, install a climate control system, navigator and on-board computer (the latter will cost you 5-10 thousand rubles).

You can also improve the dashboard by replacing the film or installing power steering. This hydraulic system will make driving easier as it makes the steering wheel easier to turn.

Photos of tuning UAZ-3303 Tadpole

After going through these basic stages, you can try to conquer the SUV. And if you have sufficient funds, you can, for example, also replace a gasoline engine with a diesel engine, which has high torque, which is necessary for driving in difficult road conditions. In addition, it is also worth strengthening the strength of the body by installing a power body kit.

High-quality and thoughtful tuning of the UAZ-3303 allows you to turn working and unpresentable equipment into a luxurious and affordable wheeled all-terrain vehicle that is not inferior to expensive foreign analogues. The Tadpole, as it is commonly called, has a solid foundation, a fairly spacious body and a cabin that can accommodate a variety of useful options. The changes will improve the functionality, off-road capability and reliability of the small flatbed truck, making it a comfortable and enjoyable experience.

Strengthening the car frame

The fact is that installing large tires entails possible damage to the car’s suspension, which is simply not designed for such fraud. In addition, the procedure for raising the suspension will protect you from possible damage to the wheel arches of the new rubber. And the car will gain unprecedented off-road capability, which is full of potholes and other irregularities.

Similar results can be achieved by taking the time to install spacers. The UAZ 3303, which you are going to tune, must have a reinforced bottom, and if the car does not have this characteristic, you need to take care of installing it. The reasons for the need to provide underbody protection are the frequent occurrence of large branches falling under the vehicle.

The body of the UAZ 3303 and its DIY repairs

No matter how famous the UAZ 3303 body is for its strength and ability to withstand merciless use, the time for replacement is coming. This is required due to normal corrosion of the metal part. Bodies for domestic cars are sold in both the first and third configurations.

History of UAZ 3303

ATTENTION! I found a completely simple way to reduce fuel consumption! You won't believe me? Even a mechanic with 15 years of experience didn’t believe it until he tried it. Now save 35,000 rubles a year on gasoline! Read more"

Note. Experts say that the strength of the UAZ is its ability to transport cargo whose weight is several times greater than the weight stated in the technical data. In this sense, the car is even compared to an ant.

Repair and replacement

As a rule, the body of this car is repaired more often than replaced. In addition, in our time it is extremely difficult to carry out a correct replacement; it is recommended to learn how to carry out repairs.

The first thing to remember when repairing a UAZ 3303 is to remove the cab. Underneath it, there could be many cracks on the chassis - the result of merciless use on bad roads.

More points:

A bumper is a must! The tuning looks better. It is easy to install in place of the factory one. There are many advantages: snowdrifts are not scary, traffic cops and pedestrians look at you with respect.
Problem areas of the body must first be trimmed, then treated with putty and painted;
Accurately diagnose doors and openings. Replace the gaskets, be sure to straighten the edges of the door and push the rubber back into place. The locks will also need to be adjusted, eliminating unnecessary touches of the door with an angle grinder;
Whether to change the coating or not will depend on taste and financial capabilities. As a rule, 5 thousand rubles are enough to replace the lining with a new one;
The car is being repaired. It is advisable to secure all the cuffs, bleed the air from the brake system, change the bearings, repair the clutch - there will be a lot of things to do;
It is also recommended to check the engine thoroughly;
Be sure to change the threshold, which rusts easily over time. It is recommended to close all voids that cannot be removed with a special compound;

You need to know that UAZ has a popular problem related to the front axle. The grenade may start knocking, and then all this will result in control problems (if the CV joint is not changed in a timely manner).

Wooden platform

Repair of wooden body 3303

For obvious reasons, this body type suffers the most over time. Although, on the other hand, if the owner does not take care of the metal surface in a timely manner, the body will leak with rust.

So, the first thing that comes to mind when renovating a 3303 wood deck is to order new wood planks. They cover the lower part of the body. It is recommended to choose the size of the boards as follows: 30x200 mm. The material must be absolutely dry and have a minimum of knots.

Wheel tuning

To increase the off-road capability of a truck, special attention should be paid to the wheels. They need to be replaced with larger ones. The maximum diameter should not exceed 24 inches. This installation is organized as follows:

springs and shock absorbers can also be replaced. The first ones must be installed longer, and the second ones must be imported;
bridges must be replaced with bars of greater width;
First, the body is raised, spacers are installed and fenders are cut out;
In addition, the differential needs to be changed. In this case, you can achieve an amazing effect: the wheels do not slip in bad weather, and the transmission will last much longer;

a winch must be installed. This is necessary to protect the glass from scratches. Most often they choose electric, as it is more reliable. However, you should also change the battery to a more powerful one.

At this point, work with the wheel part is completed, and you can move on to the next step.

Tank tuning

This item includes tank, steering wheel and engine protection. This type of setup occurs as follows:

To protect the steering wheel, you can cover it with film or any other coating.
then you should remove the air intake from the engine compartment to the roof of the UAZ 3303;
first you need to strengthen the interior. This is done using a shockproof frame;
it is necessary to install a roof rack;

Therefore, with some ingenuity and diligence, you can make a more advanced version of an SUV from the 3303 truck. If something doesn’t work for you, you can always contact any auto repair shop where the best specialists will work to help you.

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:

Manufacturing of metal body for UAZ 3303

Task: to produce a metal body for UAZ 3303

Progress of work on the manufacture of a metal body for UAZ 3303

I dismantled a wooden box from a disused GAZ-52 gait. The frame was wooden, covered with tin, but the frame was channel 8.

dimensions of the platform of the future body: 233x168 I cut out the channel joints with a grinder:

I’ll immediately note that the UAZ frame is not the same in width, from the tow bar to the distributor it expands by 1 cm:

cut a 20-channel channel into spacers under the platform and reinforce with an eighth channel

The spacers will be fixed like this:

reinforced the short one with reinforcement:

I threw a 5.5 cm corner around the edges, pierced it at the intersection with the channel:

As a result, the first phase is completed and the following structure is obtained:

Next I plan boards 50 cm high from a 40x25x2 mm profile.

Here's what happened:

cut the corner, drill with a 14-gauge drill bit and weld

I also welded lateral displacement limiters on both sides

Now, when repairing the transmission and transfer case, the body will be conveniently moved back

welded the front attachments to the frame

Cut fasteners for the frame from channel 6, adjust individually

All that remains is to weld and strengthen the front fasteners

The boards are assembled from a 3x3x0.2 profile pipe, i.e. I chose the side dimensions of 162.5x44 for the front and back and 232x44 for the sides (I assumed a height of 42, but was mistaken by 2 cm), let it be 44 cm.

I had to redo the pre-assembled front side and shorten its length, since there were still locks on the wooden sides. (The factory metal UAZ body has a full-size front panel due to a different lock design).

Cut reliefs for locks from 3.5 mm sheet metal.

Then a snag arose and you wondered how to install these same locks? Having learned nothing useful from the Internet about installing locks, I installed them with tacks and watched what happened. It turned out well (now I can’t decide: should I weld it firmly or will it be the same with the bolts?

Having calculated the finances, how much it will cost to buy awnings in a hardware store and thinking about the topic: how after GPS or crushed stone the sides will close with small gaps (we recently brought projections to a VAZ 2104 with a body, quickly dumped it with a shovel and swept away particles of gravel from the cracks between the sides and the bottom, well they didn’t want to close it. I made another irrevocable decision: I cut and welded my canopies from a wooden frame.

I installed the side walls, tried on the excess and cut off the PTSki from the old collective farm bottom with the calculation of the overlap of the sides

the hatch has not yet been repaired, the scene has been corrected for the daytime hellish heat + 34-36 degrees in the shade and stuffy. Meteorologists promise rain over the weekend, we'll see) In the meantime, the weekend is coming, let's continue designing)) maybe we could do the construction as quickly as possible, but we often have to cut it and redo it, it turns out it's like in an atelier: constant adjustment to the customer.

We decided to make canopies from waste paper. I took a three-quarter pipe, cut 3 cm, cut it to length, reduced the radius, welded it to pieces of metal cut from the side shed, welded it to the pile and, having examined the product, was satisfied:

cut a 0.2mm thick galvanized sheet from household supplies (after the veranda of the house is covered) and try it with ties. And as always at this stage, I thought: in order to weld the metal to the frame, how to rivet the front panel? (advantages of rivets - folding option, welding - difficult to disassemble). I collected everything to the heap. At this moment, the board began to take on the long-awaited finished forms (I no longer hoped that such a time would come

Result: work on the production of a metal body for the UAZ 3303 has been completed
