UAZ-3303: technical characteristics

The second generation of “tadpole”, stepping into the 21st century

The indestructible record holders and “long-livers” of the domestic automobile industry are the classic cars of the Ulyanovsk Automobile and “Tadpole”. "Tadpole" UAZ-3303 is a light-duty 4x4 off-road truck. In 1985, it replaced the previous “tadpole” truck, which had been mass-produced since 1966 (UA3-450D, UA3-452D). They are still produced today: these are modifications of the UAZ-330394 and UAZ-330364 with the ZMZ-40 engine.” Initially, its standard carrying capacity was defined as 0.8 tons. Now it has been increased to 1.225 tons.

Secrets of “longevity” in the domestic market

Having opened an archival article from the magazine “Behind the Wheel” from 1965, timed to coincide with the start of serial production of UAZ light-tonnage trucks, we learn that these delivery vehicles were designed to free Soviet medium-tonnage trucks from working with half or even a third of the body filled, and thereby contribute to savings folk remedies. Today, UAZ trucks find their main use not in cities, but in the outback, off-road. This is their “element”, where modern trucks cannot compare with them in cross-country ability.

The secrets of the popularity of the UAZ-3303 lie in the following factors:

• Simplicity of design, which allows you to show excellent technical characteristics, regardless of operating conditions. The design of the machine is not only simple, but also has the highest strength and wear resistance.
• High maneuverability and very compact dimensions; For a car of this class, category “C” is not required; “passenger” category “B” is sufficient.
• Excellent visibility (due to the wide and voluminous windshield, and also due to the fact that the truck cabin is wider than the body).
• Unpretentiousness; accessibility and ease of maintenance and repair.
• Convenient loading platform that can easily accommodate four Euro pallets of standard size 800 x 1200 mm.
• Connectable all-wheel drive with three operating modes: economical rear-wheel drive; all-wheel drive; all-wheel drive with reduction gears.

All these positive qualities of the UAZ-3303, of course, matter. But the truly decisive ones for potential buyers are the following:

• Affordable price of the car itself and spare parts for it.
• Excellent cross-country ability in any, even the most difficult road conditions.

That is why, despite being more than half a century old, classic light-duty commercial vehicles from Ulyanovsk continue to be in stable demand. If in the city their use hardly makes sense - there are many much more modern small-tonnage delivery trucks, then in rural areas, in the mountains and forests; in any regions where there are no high-quality roads and cargo needs to be moved regularly, the “tadpole” can become simply irreplaceable.

For the sake of excellent cross-country ability and a cheap price, buyers are ready to turn a blind eye to archaic ergonomics, “antique” appearance, poor comfort and not always impeccable reliability. Also, UAZ “loaves” still operate as ambulances, emergency and operational services in the outback.

Repair and replacement

As a rule, the body of this car is more often repaired than replaced. Moreover, in modern conditions it is extremely difficult to carry out a correct replacement, it is recommended to learn how to carry out repairs.

The first thing you need to remember when repairing the UAZ 3303 is to remove the cab. There may be quite a few cracks on the frame underneath - the result of merciless use on broken roads.

• Be sure to change the threshold, which easily rusts over time. It is recommended to cover all cracks that cannot be repaired with a special compound;
• Carefully diagnose doors and openings. Replace the seals, being sure to straighten the edges of the doorway and adjust the rubber in place. The locks will also have to be adjusted, cutting off unnecessary touches of the doors with a grinder;
• Problem areas of the body must first be straightened, then treated with putty and painted;
• Whether to change the upholstery or not will depend on taste and financial capabilities. As a rule, 5 thousand rubles is enough to replace the upholstery with new one;
• The chassis is being repaired. It is recommended to go through all the cuffs, pump out the air from the brake system, change the bearings, rebuild the clutch - there will be a lot of things to do here;
• It is also recommended to check the engine thoroughly;
• Bumper is a must! The tuning one looks better. It's easy to replace the factory one. There are a lot of advantages: snowdrifts are not scary, traffic cops and pedestrians look at you with respect.

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

Wooden platform

For obvious reasons, this type of body 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 rust.

So, the first thing that comes to mind in the process of repairing a 3303 wooden platform is ordering new wooden boards. They line the bottom of the body. It is recommended to select the dimensions of the boards as follows: 30x200 mm. The material must be dry and there must be a minimum of knots.

Removing used decking is also considered a type of repair and replacement. Before this operation, it is recommended to measure the position of the gas tank so that no problems arise in the future.

Perpendicular beams are aligned to the same height. It is advisable to treat new boards with an electric planer, and to increase body strength and minimize gaps, they need to be laid overlapping, as on new UAZs.

The platform is laid with boards from the edges. This is done so that the end board does not end up on the outermost board (it may be narrower than the rest, and fixing the edge to a narrow board is very inconvenient).

It is advisable to fix the boards with ordinary weave self-tapping screws. You need to screw 2 fasteners into each beam. To prevent the fixing bolts of the UAZ from sticking out, it is recommended to recess them.

A wooden platform must be treated with an antiseptic, although if the wood is of high quality, then even in this form the body will last for 20 years or more.

Metal platform

In this case, instructions are given on how to make a new body measuring 233x168 with your own hands.

Step-by-step algorithm of actions:

• We take the frame from GAZ-52;
• We cut the joints of the frame channels with a grinder.

Note. It is recommended to assemble the body directly on the frame, since the width of the UAZ is not the same - there is a noticeable expansion from the tow bar to the transfer case.

• We assemble the structure for the UAZ, weld all the elements;
• We place a 20-gauge channel under the body, and then reinforce it with an 8-gauge channel;
• Be sure to also reinforce with short stiffening ribs and corners;

• Next, on the finished platform we place sides 50 cm high, made from profile;
• We weld the lateral displacement limiters;
• We weld the front clamps to the frame;
• Don’t forget to place pads for locks cut from a 3.5 mm sheet of iron.

Note. As for the canopies responsible for opening/closing the sides, they can be thrown from a wooden platform.

More detailed information on body restoration can be obtained from photo materials. We also recommend reading other body repair instructions published on the website.

Forget about fines from cameras! An absolutely legal new product - Traffic Police Camera Jammer, hides your license plates from the cameras that are installed in all cities. More details at the link.

• Absolutely legal (Article 12.2);
• Hides from photo and video recording;
• Suitable for all cars;
• Works through the cigarette lighter connector;
• Does not cause interference to radios and cell phones.

Design features of the UAZ-3303. What has changed in modern times?

All key components and elements of the UA3 truck are located on a welded frame made of high-quality steel.

The UAZ-3303 trucks currently produced are already equipped with hydraulic power steering as standard. And as an additional option, you can order a heated seat system.

The plug-in classic drive (Part-time 4WD) allows movement in three modes:

• “2H” – rear-wheel drive. The most economical travel mode in terms of fuel consumption.
• “4H” – four-wheel drive. Used when driving on slippery roads, mud and rough terrain.
• “4L” – all-wheel drive with low gears. The maximum possible traction is achieved, which is suitable for heavy off-road conditions.

Also in modern times, the design of the wheelbase has been significantly improved. Because of this, the length of the wheelbase increased by 25 centimeters and amounted to 2,550 meters on trucks of recent years of production. The carrying capacity of the UAZ-3303 has also increased, and now one and a half tons of cargo can be safely loaded into the “tadpole” body. The overall external dimensions of the vehicle have also increased slightly: the length of modern UAZ trucks is now 4.535 m, the width of the body reaches 1.974 m, and the height of the vehicle has grown to 2.355 m.

The new UAZ-3303 vehicles use modern, more powerful, economical and environmentally friendly power units of the ZMZ-409 series, capable of delivering maximum power of 98, 112 and 117 horsepower. The front wheels began to be equipped with disc brakes (the rear brakes remained drum brakes). This made it possible to reduce the braking distance of the UAZ-3303 truck.

Small all-wheel drive truck and its parameters

In the mid-eighties of the 20th century, the outdated UAZ-452D was replaced by the UAZ-3303 light-duty truck.

The main idea when creating this UAZ model was the simplicity of the design, which made it possible to operate this vehicle in any climate and terrain conditions. The designers successfully completed this task.

The machine is not burdened with any complex mechanisms. Everything from the cab to the axles is of a simple but robust design.

All main units and components are based on a welded frame made of high-strength steel, which is also easy to repair in the field.

The cabover cab is made entirely of metal and is located above the engine, which is located longitudinally to the axis of movement.

There is good access to the engine if it needs to be serviced or repaired.

In this case, an additional advantage arises from the fact that the internal combustion engine is located inside the cabin, and it can be operated in any weather conditions.

The cabin has two seats that can be easily removed. Worm steering with roller.

The steering column is not adjustable, but it is located very conveniently and does not interfere with the driver’s control of the pedals or switches.

Visual visibility from the cabin is very good and allows you to fully control the situation, which is especially important when driving off-road.

The windshield is large, the side ones are lowered using lifts. The forces from the gearshift knob in the cab to the gearbox mechanism are transmitted using rods, so additional attention is required to their correct adjustment.

The body or cargo platform is made mainly of wood. If necessary, the truck is equipped with wooden arches and an awning.

All three sides are folding. The car has dependent suspension both front and rear. There are semi-elliptic springs, the front and rear ones differ in thickness and number of leaves.

Each axle has two shock absorbers. The rear axle is driven, the front axle is geared, connected.

Technical characteristics of UAZ-3303:

Modifications UA3-ZZOZ

Modern modifications of the “tadpole” are as follows:

• UAZ-330364 - modification with a wheelbase increased to 2,550 m, a metal or wooden cargo platform.
• UAZ-330394 is a truck with a double cabin and a wooden platform.

In the past, the main model of the UAZ-3303 often served as the basis for all sorts of small-scale modifications and chassis with all sorts of special add-ons (the PTS had the index “ZZOZ” with the note: “other passenger cars”). Examples of such vehicles are milk transport vehicles, utility vehicles, etc.

Truck engines of the UAZ-3303 series

The power unit of the UAZ-3303 is located longitudinally on the axis, under the solid metal cabin. You could even say – directly inside the cabin. This has its pros and cons. Despite the absence of a hood, access to the engine is very convenient, thanks to which a significant part of the maintenance and repair of the car engine can be carried out while sitting in the cab. In frosty weather, the running engine additionally heats the interior. But in the heat it, of course, noticeably aggravates the heat.

UMZ-414

From 1985 to 1989, a modification of the UAZ-3303-O1 was produced with an UMZ-414 engine with a power of 77 to 90 horsepower. It was a carburetor four-stroke engine with in-line cylinders and overhead valves, produced since 1978. It represented a further development of the UM3-451 motor. Like the 451st, the UM3-414 engine block differs from its predecessor in increased rigidity and a separate bracket for packing the oil seal at the rear end of the crankshaft, as well as a modified design of the front crankshaft oil seal - it has become external.

The engine uses: a new design intake pipe, a cylinder head with improved intake and exhaust channels, an increased performance oil pump, a closed crankcase ventilation system, parts and components of increased reliability and wear resistance. The products were awarded the State Quality Mark.

Some technical parameters of the UM3-414 motor:

• Working volume – 2.445 l.
• Cylinder diameter – 92 mm. The piston stroke is 92 mm.
• Compression ratio - 6.7 (4144.10 - 8.2).
• Rated gross power – 414.10; 4141.10 - 56.6 kW (77 hp); 4142.10; 4143.10 - 58.8 kW (80 hp); 4144.10 - 66.2 kW (90 hp).
• Maximum gross torque at crankshaft speed at 2200-2500 rpm – 414.10; 4141.10 - 166.7 N.m (17 kgf.m); 4142.10; 4143.10 - 168.7 N.m (17.2 kgf.m); 4144.10 - 181.4 N.m (18.5 kgf.m).

UMZ-417

At the end of the eighties, the design of the truck was changed in order to improve its technical characteristics. Including the power unit was replaced with a more modern and powerful analogue UM3-417 - with a new cylinder head, improved design, cast iron camshaft. The engine fuel system was equipped with a two-chamber carburetor with an electronic K-151V sensor and an innovative intake manifold for that time. This made it possible to increase the performance of the power unit and increase its power by almost ten horsepower. At the same time, the standard carrying capacity of the vehicle increased by 425 kilograms, to 1,225 tons. In appearance, UM3-417 is practically no different from UM3-414.

The cylinder head of the UMZ-417 engine is distinguished by an individual camshaft made of cast iron, the diameter of the intake valves increased from 44 to 47 mm and an original intake manifold - with round windows in the head, but for a two-chamber carburetor (K-126GU or K-151V). The 417 engine has an increased compression ratio from 6.7 to 7.0, which provides higher power - 88.5–92 hp. With. according to GOST. The interchangeability of parts UM3-414 and UM3-417 is about 90 percent. These engines run on 76 (80) gasoline.

3M3-409

The ZMZ-409 engine was created on the basis of the 406th engine, or more precisely, on the basis of its successor ZMZ-405. The 405th block is used (the height of all blocks 405, 406, 409 is the same), the crankshaft has an increased stroke (from 86 mm to 94 mm), the connecting rods remain the same, the pistons are changed, with a displacement of 4 mm.

On “loaves” and “tadpoles” its deformed lower modifications 3M3-4O91.1O and 3M3-4O911.1O were used. UAZ-3303 trucks are still equipped with the second of these options. This is an injection gasoline engine that meets the requirements of the Euro-5 standard. Its working volume is 2.693 liters; maximum power is 82.5 kW, or 112.2 hp. Maximum torque at 2500 rpm – 198 N.m. Fuel consumption at a speed of 60 km/h – 9.6 liters per 100 km; at a speed of 80 km/h – 12.4 liters per 100 km.

This engine is distinguished by consistently confident starting at low air temperatures, quick warm-up, unpretentiousness to fuel quality, and throttle response (an optimal combination of torque and power). runs on 92 gasoline.

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.

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.

This review examines the technical characteristics of the Isuzu Elf truck.

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.

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.

Transmission

The clutch on the UAZ-3303 is single-plate, with a hydraulic release drive. Gearbox – 4-speed, with the following gear ratios: I-3.78; II-2.60; III-1.55; IV-1.0; Z.H.-4.12. Synchronizers are provided in all forward gears (but some cars were produced with a gearbox with synchronizers only in 3rd and 4th gears and other gear ratios).

The transfer case is two-stage, with gear ratios: I-1.94; II-1.00. There are two cardan shafts to the drive axles, there is no intermediate shaft between the gearbox and transfer case. The main gear of the front and rear axles is single, bevel with spiral teeth, gear ratio 4.625 (before 1991 this gear ratio was 5.125).

Frame and body design of UAZ-469, UAZ-31512, 31514

Frame UAZ-469, UAZ-31512, 31514

The car frame (Fig. 1) consists of two longitudinal beams 3 connected to each other by five cross members.

Four cross members are welded to the longitudinal beams by electric arc welding, one cross member 8 (the second from the front) is bolted to brackets welded to the longitudinal beams of the frame.

Fig.1. Frame UAZ-469, UAZ-3151, 31514

1 — supports for front spring brackets; 2 — cross member No. 1; 3—longitudinal beam; 4 and 7 — engine mounting brackets; 5 — amplifiers of longitudinal beams; 6 — front body mounting brackets; 8 — cross member No. 2; 9 — middle body mounting brackets; 10 — cross member No. 3; 11 — rear body mounting brackets; 12—cross member No. 4; 13 — cross member No. 5; 14 — supports for rear spring brackets; 15 — rear shock absorber mounting brackets; 16 — brackets for fixed air springs of the front springs; 17 — brackets; 18 — body tail mounting brackets

All brackets are welded to the frame, only two brackets for the 16 fixed ends of the front springs are riveted.

A towing device (Fig. 2) of a double-acting closed type is attached to the rear cross member of the frame, which is equipped with a rubber elastic element 4, which softens shock loads when starting a car with a trailer, as well as when driving on an uneven road.

Maintenance of the frame of the UAZ-469, UAZ-31512, 31514 consists of periodically cleaning it from dirt and checking by external inspection the condition of the longitudinal beams, cross members, brackets, as well as welded, riveted and bolted connections.

It is necessary to periodically carefully inspect the left longitudinal beam of the frame in the area where the steering housing is mounted for cracks.

It is very important to monitor the condition of the painted surface of the frame and promptly touch up places where the paint layer is damaged.

Maintenance of the towing device consists of periodically cleaning it from dirt, checking its condition and reliability of fastening to the rear cross member of the frame, as well as lubricating the rubbing surfaces according to the instructions in the lubrication card.

Fig. 2 – Towing hook UAZ-469, UAZ-31512, 31514

1-cap, 2-support nut, 3-housing, 4-elastic element, 5-bracket, 6-tow hook, 7-pawl, 8-latch, 9-chain, 10-bolt with nut, 11-grease nipple , 12-washers, 13-cotter pin

The hook of the towing device UAZ-469, UAZ-31512, 31514 must rotate freely around its axis and not have any noticeable axial movement in the body.

This is achieved by adjusting the support nut 2 (see Fig. 2) of the hook rod. The latch should tightly close the hook mouth and be securely locked by the pawl.

Lubrication of the rubbing surfaces of the neck of the hook rod and the hole in the bracket 5 is carried out through the grease nipple 11.

The rubbing surfaces of the support nut 2 and the holes in the housing 3 are lubricated with lubricant placed under the cap 1 when assembling the towing device.

When the vehicle is overloaded or in the event of an accident, distortions, bends, cracks and other damage may appear in some places of the frame, requiring frame repair. In addition, during operation, the rivet connection of the front spring brackets may become loose.

Fig.3. Main frame dimensions of UAZ-469, UAZ-31514, 3151

Before repairing, it is necessary to clean the frame from dirt, carefully inspect it and identify all damage.

If, during inspection and testing, a violation of the correct shape of the frame is found, then it must be straightened in a cold state using devices.

In this case, you should be guided by the dimensions indicated in Fig. 3. In addition, the difference between dimensions A and B should not exceed 5 mm.

After straightening the frame, it is necessary to check the perpendicularity of the axis of the spring brackets to the vertical plane of the frame, and also pay special attention to the correctness of the section of the frame where the steering housing is attached.

Cracks in frame parts must be sealed using electric arc welding. Before welding, it is recommended to chamfer the crack edges at an angle of 60°.

If there are long cracks on longitudinal beams and cross members, in addition to welding the cracks, it is necessary to weld a reinforcement applied to the welded area.

The amplifier must be tightly fitted to the surface of the damaged area. Before welding the amplifier, clean the weld seam flush with the surface.

The amplifier can be welded both from the inside and outside, depending on the location of the crack and the ease of doing the work.

It is not recommended to weld the reinforcement with a weld seam running across the longitudinal beam, especially in the vertical direction, since such a seam weakens it and creates the possibility of frame breakage in this place.

To ensure greater strength of the UAZ-469, UAZ-31512, 31514 frame and weld seam, the seam should be made at an angle of 45°.

The reliability of rivet joints is checked by tapping them with a hammer. Loose rivets produce a rattling sound when tapped.

If a weakening of the rivet connection of the front spring brackets is detected, the weakened rivets must be cut down and replaced with new ones. In this case, the holes for the rivets should be drilled out and rivets of larger diameter should be installed.

Before this, it is necessary to cut a window in the longitudinal beam reinforcement opposite the bracket for access to the rivets on the inside of the longitudinal beam, and after riveting, weld the window. The fit of the rivet head to the surface of the part must be tight.

If it is impossible to repair the rivet joint, the rivets can be replaced with bolts and nuts. Repair of the towing device consists of replacing worn and damaged parts.

Do not use the towing device to tow a trailer after fixing a bent hook and latch. In this case, damaged parts must be replaced with new ones.

Body UAZ-469, UAZ-31512, 31514

The body shell of UAZ-469, UAZ-3151, 31514 cars is of metal, welded construction.

In the floor of the body there are hatches (Fig. 4), closed with covers, for access to transmission units, the parking brake, the filler plug of the main brake cylinder, as well as to the sensors and receiving pipes of the fuel tanks.

Cabin of UAZ-3303

The truck cab is an all-metal double cab, with two side single-leaf doors and a removable engine hood cover. The large windshield provides good visibility, which is very important when driving in off-road conditions. The archaic interior of the UAZ-3303 has now been largely modernized. The front seats now have an integrated headrest, and the driver's seat is equipped with longitudinal adjustment.

The ancient “bone” steering wheel has now been changed to a more pleasant and comfortable grip, made of modern plastic. The only instrument left was the speedometer, which was moved to the center of the front dashboard. All minor indicators must now be read from the LCD display. And in the interior of the UAZ-3303 there was a 12-volt socket and a socket for a single-din radio.

The engine casing is now covered not with dermantine leatherette, but with carpet, which better absorbs noise. Indeed, the cabin has become quieter! Even with active acceleration, it became possible to talk without breaking into a scream. All this somewhat modernized the interior of the “tadpole” cabin, which remained in an “antediluvian” state. Structurally, the car has not changed - the engine and chassis are the same. Although in general, of course, the cabin of Ulyanovsk cabovers, even after modernization, did not become modern or even close to modern in terms of comfort and ergonomics.

330364: equipment features

This name has been used since 1997. This meant that the model range of UAZ trucks was updated and again received improved technical characteristics. Assembling the body of a UAZ 3303 with your own hands is not difficult.

The difference from previous versions was not only qualitatively new engines. The base of the car has become longer compared to its predecessors. The increase in dimensions was 25 centimeters. Other technical characteristics can be described as follows:

1. The vehicle's carrying capacity has increased by 200-300 kilograms. Now it was 1200-1500 kg.
2. The track has retained the same dimensions.
3. The fuel tank volume increases to 112 liters.
4. Installation of new engines, whose power is 98 and 117 horsepower, respectively.
5. The front wheels began to be equipped with disc brakes. The rear ones remained the usual drum ones.
6. Increased comfort inside the cabin. Installation of soft seats with additional adjustment. The steering wheel is replaced with a more convenient option. It is now possible to select power steering upon request.
7. Metal cargo platform, with the addition of folding sides. UAZ with a body is also equipped with it, model 3303 is no exception.

Reviews from UAZ-3303 truck owners

The owners of the “tadpole” - residents of the Russian outback - note the following advantages of this off-road truck:

• the opportunity to go hunting, fishing, picking mushrooms and berries; transport any household goods in any of the most inaccessible places;
• unpretentiousness, ease of maintenance and repair: you can, if necessary, repair the machine using a set of standard tools, and spare parts for it can be found in any region or locality;
• the lowest price in the class of light-duty trucks, with the best cross-country characteristics.

The tadpole engine provides consistently excellent low-end traction. The UAZ's ideal adaptability to our roads sets it apart from commercial foreign cars of this class. In contrast to them, which have the dynamics and comfort of a passenger car, moving in traffic on a UAZ-3303 reminds the driver of driving a truck. “You try to stay on the right side, because the dynamics are not important. You constantly monitor the dimensions and look down on passenger cars. Thanks to the high ground clearance and all-wheel drive, there are no problems with high curbs, deep puddles, large snowdrifts or icy roads in winter. The suspension confidently absorbs road irregularities. At the same time, there is only a slight wobble in the cabin.”

Long climbs from acceleration UAZ-3303 passes confidently in 4th gear. Less often, if the speed and engine speed are not enough, you have to move in 3rd, and this is in 2nd gear.

Most owners speak of the UAZ-3303 as a real “workhorse” for harsh operating conditions, capable of almost anything. And they even call this car a reliable friend who will always help and never let you down.

Of course, there are also plenty of disadvantages, given the considerable age of the model. The seat, compared to modern “classmates”, is uncomfortable, as is the location of the pedals. It takes some getting used to the controls. After all, the steered wheels are not in front of the driver, but even slightly behind (under the driver’s seat). And when turning, you need to get used to it. Also, the steering column stands a little obliquely in those UAZ-3303s where there is no power steering yet). Another difficulty is changing gears. The gearshift lever does not immediately enter the gearbox, but is connected to it by rods. Accordingly, you also need to adapt to this.

Those who had experience driving a “tadpole” with the previous version of the engine, and now tried it with the new injection 3M3, note a noticeably increased power and dynamics. From a traffic light, in second gear, the “tadpole” moves forward more confidently than other cars, and on the highway it can be accelerated to a previously unimaginable 140 km/h. And fuel consumption in any case turns out to be very modest for an engine of such a displacement.

Overall, the car is very good, even ideal for its niche - regions with difficult road conditions. Suitable for private households (low fuel consumption, low insurance and taxes). Strong, durable, inexpensive to maintain. Indispensable for outdoor enthusiasts, farmers, beekeepers, and forestry workers. The appearance is, of course, “antique”. But the UA3-ZZO3 was designed as a means of transportation on bad roads and off-road, and not as a Lamborghini.

ZMZ-409: latest modification

It was created on the basis of one of the previous engines - 406. Characteristic in this case is the use of the following parts:

1. Block 405 series. The height of all blocks remains approximately the same.
2. Crankshaft, the stroke of which increases to 94 millimeters.
3. The connecting rods are the same as previous models.
4. Modified pistons, with an added offset of 4 millimeters. The length of the body does not depend on this.

Currently, preference is most often given to the injection gasoline variety of engines. It fully complies with the requirements of the Euro-5 standard. The characteristics of the motor are as follows:

1. The working volume is 2.693 liters.
2. 112.2 horsepower – maximum power.
3. At 2500 rpm the power reaches 198 Nm.
4. The unit consumes 9.6 liters of fuel per 100 kilometers.

Stable starting even at low temperatures is a distinctive feature of this series. There is quick warm-up, unpretentiousness in relation to the types of fuel used. The load capacity will suit any buyer.
