417 UAZ engine - Technical characteristics, advantages

Popular to this day, the domestic jeep

The UAZ 469 all-terrain vehicle, which appeared in our country in the early 70s of the twentieth century, remained for a long time the best domestic SUV. Thanks to its high reliability, maintainability in field conditions and low price, this unpretentious hard worker still remains the standard all-wheel drive vehicle for many.

Indeed, what other car can you fill with a cloudy brownish liquid called A-72 gasoline, used motor oil and castor oil instead of brake fluid, and then drive our entire great country from end to end without ruining the engine and brake system. The technical characteristics of the UAZ 469 are unique; they allow this SUV to be used in conditions that would kill any other vehicle.

The “goat” also has disadvantages, in particular, a tarpaulin awning instead of a normal roof and a weak stove, which make your teeth chatter when traveling in the winter season. But they are more than compensated by the awareness of the fact that along the way you won’t get stuck in a snowdrift and freeze your limbs.

UAZ 31512: technical specifications, photos, weight of the model with an iron roof

Since the late 1980s, the Ulyanovsk Automobile Plant began widely selling UAZ passenger cars to the public. From that time on, with the onset of market relations, as well as a sharp decrease in purchases of UAZ vehicles by government organizations, the plant had to begin to respond to the demands and demands of the market, gradually demobilizing its main products, which also had imported competitors, albeit much more expensive ones.

Many small companies had previously made hard tops for the UAZ-469 and UAZ-31512 models, and since 1993 the plant itself began offering consumers the UAZ-31514 with a metal roof. A year later, the SUV received an undivided windshield. The plant also began installing plastic instrument panel cladding on some cars, front seats on Zhiguli skids, backrest adjustment, fabric upholstery, and headrests.

The UAZ-31514 has become an example of how it is possible to improve the consumer qualities of an old model without high costs and changes in technology. The interior and ceiling were insulated, a roof lining was added, as well as seals for openings and joints. As a result, the cabin became much warmer and quieter compared to the UAZ-31512, but of course not with passenger cars. The doors finally received locks and internal locking.

Disconnectable front axle clutches appeared. The carburetors were replaced with modified Volgov K-151V and K-126GU. Since June 1994, part of the production, additional index 10, was equipped with a new front spring suspension with anti-roll bar and a rear suspension with small leaf springs - this made it possible to improve the smoothness of the vehicle with the same load capacity, but this convenience made the car somewhat more expensive and the front and rear were no longer interchangeable shock absorbers.

The plant did not stop there and subsequently made many minor changes to the design of the UAZ-31514, mainly in relation to the interior. Thus, the inconvenient solid and always getting wet floor carpet was replaced with a composite one, the cleaning of which did not pose any problems, the door mats were no longer glued, but secured with plastic clips, the windshield wiper drive was moved to the lower part, like other cars, armrests on the doors and handrails appeared above them. The gas tank hatches, there are two of them on the UAZ, received locks.

With the advent of a more powerful 98-horsepower UMZ-4218 engine with a displacement of 2.9 liters, UAZ expanded its model range. An extended model UAZ-3153 and a standard UAZ-31519 with the same power unit appeared.

What causes rapid wear of the UAZ 417 engine

Among the main factors, the first place is the use of motor oil of inadequate quality or non-compliance with the maintenance schedule of the internal combustion engine. The next problem is the failure to timely seek qualified assistance in the event of minor defects in the operation of the power unit. It is known that at the slightest knock and even after it stops, the defect does not disappear.

Repair of the UAZ 417 engine is divided into types:

1. Urgent Care.
2. Partial renovation.
3. Major renovation.

In the first case, the defects that have appeared in the operation of the motor are eliminated. This is enough to temporarily extend its viability. Such assistance is provided to the engine if a breakdown occurs on the way, so that the car can be delivered to the nearest service center for subsequent diagnosis and elimination of identified faults.

During partial repairs, the motor is checked on special stands. After this, worn-out components and parts are selectively dismantled in order to replace them with new spare parts.

Important: Major repairs are the most labor-intensive procedure. To carry it out, highly qualified auto mechanics are involved, familiar with the features of the device and the characteristics of the UMZ 417 engine.

There is a trend in the global automotive industry: cars created for military purposes are converted into civilian versions.

Examples of this are the Geländewagen SUVs from Mercedes-Benz, Hummer from General Motors, Jeep Willys from DaimlerChrysler, and LAND ROVER from the company of the same name. UAZ-31512 is a modified version of the UAZ-469B, created on the basis of the military UAZ-469.

The Ulyanovsk Automobile Plant began producing cars in 1943. The enterprise, formed on the basis of the evacuated Moscow Automobile Plant, produced aviation ammunition, ZIS-5, UlZIS-253, GAZ-AA cars during the war.

In 1956, having mastered the production of the GAZ-69 SUV, the plant was officially considered as specialized in the development and production of low-tonnage off-road vehicles.

Fault overview

All engines are repaired and serviced early. This is necessary because engines, like cars, are designed for use in difficult conditions. And in modern Russian conditions, when using low-quality diesel fuel, the filter devices in the engine become clogged. This happens especially often in winter. As a result, the car loses traction and ceases to be powerful. In the worst case, it might just end up in the middle of the road.

Attention! Experienced mechanics recommend performing maintenance every 10 thousand kilometers. This will increase the service life of the power unit.

Another weak point is the 5-bearing crankshaft, which is cast from cast iron. When overheated, it cracks. If not noticed in time, it will fail and its destruction can harm the entire engine. This is why maintenance at 10 thousand kilometers is so important. Since operation in difficult conditions makes itself felt by all kinds of overheating and wear.

The UAZ engine begins to consume a lot of oil when the crankshaft seal breaks. The problem is also observed in the cylinder head. Aluminum alloy quickly cracks and the cylinder head becomes unusable before the service life of the entire engine.

Due to clogged air filter devices, engines can consume too much fuel. Experienced mechanics advise changing the filter after a run of 20 thousand kilometers.

However, from a number of advantages of the power unit on the UAZ 469, the following can be highlighted:

• repairable. All engine models can be repaired in a garage;
• lower fuel consumption compared to other engines, for example Japanese ones. Engines from Japan, created specifically for SUVs, consume up to 20 liters at a minimum. This one is no more than 15;
• The UAZ 469 can transport cargo over long distances. The engines of this machine can withstand serious overloads.

If the engine breaks down and there is no suitable engine for the car nearby, then the UAZ 469 is usually equipped with a two-liter 2 ST from Toyota. He copes well with the actions assigned to him.

If money allows, car owners usually change the engine to a Nissan TD 27. This is also one of the most reliable engines. He is hardy and does not require close attention.

Description

Weight -132kg. Width -0.45 m, Height -0.35 m, Length -1.77 m.

Front axle (3741-2300011) UAZ-452, UAZ 469 (3151-2300011).

Front axle (3741-2300011) UAZ-452, UAZ 469 (3151-2300011 ) from

There are two types of front axles installed on cars - with a single main gear or with additional wheel reduction gears.

The bridge with a single main gear consists of a cast-iron crankcase that is split in a vertical plane and steel tubular axle housings pressed into it, additionally fixed by welding. The crankcase halves are bolted together through a gasket. The main gear with the differential is located in the left half of the crankcase and forms the axle gearbox.

The main gear drive gear is installed in the crankcase on double angular contact roller and radial roller bearings located on both sides of its ring gear. The driven gear is bolted to the gearbox. The gears are bevel gears with a spiral tooth, the gear ratio is 4.625.

The satellite box consists of two halves connected by bolts. It is installed in the crankcase on two tapered roller bearings. The box contains two satellite axles, four satellites and two semi-axial gears with thrust washers.

Adjustment of the bearings and the engagement of the main gear gears is carried out by changing the thickness of the gaskets between the inner rings of the drive gear bearing and the number of washers at the inner rings of the satellite box bearings.

On a bridge without wheel reduction gears, a ball joint with two holes into which bronze bushings are pressed is bolted to the flange of each axle housing. The bushings include two kingpins that are pressed into the steering knuckle. A hollow axle is bolted to it, on which two identical tapered roller bearings of the wheel hub are mounted. Five bolts are pressed into the hub, to which a stamped steel wheel with a landing diameter of 15 or 16 inches is attached with cone nuts. The hub bearings are adjusted by nuts installed on the threaded end of the axle.

Each axle shaft consists of a driving and driven part connected by a Weiss constant velocity ball joint. The hinge is located inside the ball joint and consists of two profiled knuckles that engage with each other through four balls located in their grooves. The fifth (central) ball is located in the center of the hinge on the same axis with the pivots. The driven part of the axle shaft passes inside the axle and is connected to the drive flange of the hub through a splined wheel release clutch. The flange is attached to the end of the hub with studs through a gasket.

The front axle with wheel reduction gears is distinguished by:

a gearbox with a spur gear internal gear and a gear ratio of 1.94 is attached to the steering knuckle body; the main gear drive gear is mounted in a cantilever on two tapered roller bearings with a spacer sleeve between them; the final drive ratio was reduced to 2.77, and accordingly, the dimensions of the final drive housing were reduced.

The drive gear of the gearbox is mounted on the splines of the driven part of the axle shaft.

Thanks to the use of wheel gears, the vehicle's ground clearance increases by 80 mm, which increases its maneuverability.

The main gear and wheel gearboxes are lubricated with transmission oil poured into their crankcases. The main gear housing and wheel gearboxes have holes for oil changes, closed with plugs with conical threads. The hub bearings, constant velocity joints and king pins are lubricated with grease.

To prevent the leakage of oil and grease, as well as to protect against the penetration of dirt inside, the front axle is equipped with gaskets between the fixed parts, cuffs in the hubs and on the drive gear shaft, as well as combined felt-rubber seals sliding along the spherical surface of the ball joints. To prevent oil from the gearboxes from penetrating into the cavity of the ball joints, cuffs are installed on the axle shafts, and the ball bearing of the wheel gearbox has an oil deflector.

Maintenance of UAZ 417 engines

The list of maintenance work for an internal combustion engine includes the following items:

1. Checking the level and condition of the engine oil.
2. Replacing lubricant.
3. Filter elements.
4. Spark plugs.
5. Timing belt.
6. Timing guide rollers.

According to experienced specialists, changing engine oil should be carried out in accordance with the requirements set out in the vehicle’s service book. It says that the oil in the engine is changed after the next vehicle mileage of 10,000 kilometers; this will require 5.8 liters of working material. This document also indicates the brands of recommended lubricating fluids:

• M-8B SAE 15W-20;
• M-6z/12G SAE 20W-30;
• M-5z/10g1;
• M-4з/6B1 SAE 15W-30.

The UAZ 417 engine has a standard oil filter called NAMI VG-8-R-1. Along with changing the engine oil, it is recommended to change the filter elements. The oil filter does not need to be cleaned, but replaced with a new, similar or imported model. The spark plugs for the UAZ 417 engine must also be replaced.

Important: Before changing the engine oil, check its level and general condition. This is necessary to determine how worn the metal surfaces of the working parts of the internal combustion engine are. At the same time, the feasibility of carrying out a major overhaul of the power unit is also determined.

Purpose and history of the model

This is a utility vehicle with a drive on both axles, with increased cross-country ability, allowing operation on any type of road surface.

In the army it was widely used as a command and staff and reconnaissance vehicle, a light tractor, and for other purposes and tasks.

It was used by law enforcement agencies, in geology and topography, and served as a service vehicle in rural areas, remote, inaccessible areas.

In 1972, the plant launched production of the UAZ-469 in two modifications.

The army model has the following parameters:

• ground clearance 300 mm;
• double final drive on drive axles;
• Onboard reduction gear mechanisms were installed on all wheels;
• springs made of 9 sheets.

The civilian modification has the following characteristics:

• ground clearance 220 mm;
• on the drive axles there is a single main gear;
• springs made of 7 sheets.

The 469 series used the UMZ 451M 75 hp engine. With. power and 2.5 liter volume, which has good technical characteristics.

In 1985, the Ministry of Automotive Industry changed the designation system for car models - the 469th model began to be designated as UAZ-3151. Truck 469B was renamed UAZ-31512-010.

Comparative Specifications

Engine

Over the years, engines were installed on the car that had a common ancestor - the GAZ-21 engine. Four-cylinder engine with four strokes per cycle.

The power supply system is carburetor, overhead valve arrangement, liquid-type cooling, inertia-oil air filter design.

Since 1985, carburetor devices K-131A were installed on the car instead of K-129V with a DAAZ starting system and an EPHH valve, which reduced fuel consumption and reduced emissions of harmful substances.

Clutch assembly

Dry, single-disc, friction, with springs on the periphery, hydraulic shutdown drive. A mechanism for damping torsional vibrations is provided.

Gearbox and transfer case

For 4 modes, all forward gears with synchronizers, adjustments are not provided. The transfer case is of a mechanical type, with two stages of transmission of rotational force , allowing the use of an additional reduction mode.

Cardan transmission

Open, consists of two shafts, the rear one is tubular, the front one is a pipe and a solid shaft. The shafts are equipped with movable spline units (straight-sided or involute) and swivel joints on needle-type bearings.

Front and rear axle

Rear axle type - drive, modernized in 1988.

To improve dynamic performance, other characteristics were selected on the main gearbox pair. To increase the reliability of the unit, more effective parameters for the engagement of the axle gears were used. The front axle is a drive axle. The design of the main gear pair and differential corresponds to the rear axle.

Frame and towing device

It is made of two box-shaped steel beams, which are connected by cross members.

The frame of the UAZ-31512-010 model in the front part has spring suspension installation units; for other modifications, the frame devices provide for the installation of leaf springs at the front and rear.

The standard towing device is of a rigid type and does not allow long-term towing of a trailer.

Suspension

The UAZ-31512-010 model, like most modifications, has spring suspension on the front and rear axles. Spring type is semi-elliptical, multi-leaf.

The knot is made up of seven sheets at the front, and nine at the back. To increase comfort and improve vehicle handling, the UAZ-31512-010 is equipped with a spring suspension at the front.

To reduce the transmission of impact impacts from uneven road surfaces to the body, a pair of double-acting hydraulic shock-absorbing devices are installed in the suspension.

Hubs, wheels and tires

The wheel hubs for the rear and front axles are identical in design. They have 8 threaded holes for bolting flanges.

Wheel rims are steel, stamped with dimensions 6Lx15 or 6Lx16. 15-inch diagonal or 15- and 16-inch radial pneumatic tires are used.

Electrical equipment

Assembled according to a single-wire circuit, the negative contact of a 60 Ah battery is connected to the housing.

Two types of alternating current generators were installed: with built-in rectifier elements and a voltage regulator; with voltage regulation integrated circuits. On the latest modifications, a contactless ignition system was installed.

What diesel engine can be installed on the UAZ 469 without modifications?

This question is always relevant for car owners who have a similar car model for private use. A diesel engine has many advantages over a gasoline engine.

Operating a diesel engine is cheaper, fuel costs are lower, and the gain in power is significant. Diesel from foreign car models is best suited for the UAZ 469. The simplest, most unpretentious, budget engine is a naturally aspirated two-liter 2C-T from a Toyota with 88 horsepower.

If we consider more reliable expensive options, then for more comfortable movement and transportation of goods, NISSAN-TD27ETi power units with 130 horsepower are suitable. Diesels from Mercedes models OM 616 and OM 617 received maximum popularity for installation in UAZ. This is the most reliable and unpretentious diesel engine in the UAZ 469, most often installed on these car models.
