3303 Model UAZA

UAZ 3303 - good in every sense, a practical pickup, who has found its application both in different public services and in private hands. Debuting back in 1985, it is still available to this day. Under the hood, several types of gasoline engines are installed. Works with rear wheel drive and five-speed mechanical gearbox. You can install UAZ 4216, 402, 421 engines on the car.

Each of the engines is sooner or late repair, and the driver in a hurry is trying to find the right answer to the question of which motor can be put on his car instead of the failed.

Engine specificity UAZ 417

Gasoline engine UAZ 417 or UMP 417 is a row, carburetor, four-cylinder, two-flaped force aggregate. For the first time this motor Appeared in 1989, his issue is also underway. The unit is made of aluminum, which makes it easier and efficient. The engine is characterized by a good power, endurance, durability, unpretentiousness - the main qualities for the SUV. Piston stroke - 92, volume - 2.5 liters, power - 92 liters. s., Torque - 172 nm. The power unit corresponds to the Eurostandard 1, has the quality of moderate economy, 100 km of the path burns 14.5 liters of fuel in urban mode, 8.4 liters on the highway and 10.5 liters - in mixed mode.

It's really reliable engine

417 is an evolutionary step in development, he replaced UMZ 414, which is morally outdated in the 70s. Unlike its predecessor, 417 has best characteristics, more reliable and effective. It has larger valves and new air filter. Motor UAZ 417 is made in four modifications, each of which has its own range of destination. VEZ 402 engine has similar characteristics.

• 417.10 with a capacity of 92 liters. from. put on UAZ 3303, as well as new projects, UAZ Hunter and UAZ Patriot, consumes 76 gasoline;
• 4175.10 with a capacity of 98 liters. from. It is installed on the Gazelle car, uses 92 gasoline;
• 4178.10 - as the first, put on UAZ 3303, UAZ Hunter, UAZ Patriot and some other cars of this brand;
• 4178.10-10 - Analogue of the previous unit, mounted on many UAZ cars.

Like any vehicle assembly, the power unit is wearing over time. If you have a 417 UAZ motor, repair will create not so much problems as an imported engine, but still has its subtleties. If necessary, this engine can be replaced without any problems with UAZ 402.

Motor malfunctions are overheating, the appearance of the knock, vibration. The reasons are in the wear of individual details: cams, bearings, springs, washers and other things. Therefore, it is better to regularly check the status of the engine, to prevent breakdown in time, rather than spending much more time for its correction.

What affects engine wear

First, the motor wear is influenced by poor, poor-quality or long used waste oil. If you constantly forget to change the lubricant, do not think that the engine will work well on the old one. The problem may not immediately let yourself know, but then will deliver quite a lot of trouble.

Poor-quality engine oil destroys the motor

Secondly, if you do not immediately eliminate a small flaw in the work of the engine, it will very soon turn into a serious breakdown. Hear a light knock in the engine? Go to the workshop or yourself to beat the motor. Even if the knock suddenly stopped, the defect from this did not disappear on the manual of the magic wand.

Diesels are subject to overheating pistons and, as a result, extending parts. Too intense load on the engine will quickly strike it. It is advisable to relate to the engine more carefully.

Motors 402, 417 UAZ Repair is three types.

1. First ambulance - Elimination of job flaws for temporary extension of engine life. Such ambulance becomes the necessary measure when the breakdown found the driver somewhere on the way.
2. Partial repair. Includes verification and incomplete dismantling in order to identify and replace defective parts.
3. Overhaul. This is a very time-consuming procedure requiring responsibility and knowledge. Given the features of motors 402, 417 UAZ, repair will require a lot of patience.

Each driver at least once in his life conceived over the issue of improving its car both in the design and technical filling. Tuning UAZ cars is a real opportunity to upgrade the vehicle.

To get more horses, you need a replacement of the engine to import. Excellent suit Motor From Toyota - 2L-T. He is the most universal, practical. You can put domestic motors with more powerful indicators, but Japanese will still be cost-effective.

Improved engine UAZA

What do we get in the end? First, the control-dispensing system, secondly, high-speed capabilities will significantly improve. When installing the Toyotovsky engine, fuel consumption is also reduced.

Overhaul 417 UAZ

List of works:

• diagnostics of the problem;
• engine dismantling;
• cleaning parts;
• identifying defects and replacing spoiled parts to new;
• motor installation.

Replacing the crankshaft of 417 motor

Diagnostics is the most time-consuming and responsible stage, because the outcome result depends on the correct diagnosis. There may be weight problems, from typical overheating to unbalance. You can identify the problem using a special volumetric table. Quite often the cause of the breakdown becomes the defect of the crankshaft or the head of the block. The first flaw is eliminated by grinding, the second - welding cracks.

If we are talking about Motor 417 UAZ, the repair must be completed by adjustment, since the working parts can be knocked out. When repaired carburetor Engine Adjustment is carried out:

• interrupter of ignition, the state of contacts and angle;
• idling speed;
• the level of toxicity of the motor.

Overhaul of the engine 417 UAZ will cost from 3,000 to 4,000 rubles. If you repair an imported motor, the price will be slightly higher: up to 800 dollars, if it is a simple unit, and up to $ 4,000, if the engine is 8- or 12-cylinder.

24.04.2017

The cargo model 3303 from the Ulyanovsky Automobile Plant is one of the series of all-wheel drive cargo-passenger cars, which also included a van, minibus, medical cars and a carriage model (farmer).

The model called the model for more than half a century of the "loaf" for more than half a century, and under the hood she has evolving gas-21 engines. Some modifications of power units are now put on UAZ Hunter and Patriot.

Engine UMP 417 / 4175/4178 2.45 l

Another step in improving the GAZ-21 motor was the engine UMP 417 with an increased degree of compression, altered camshaft, new 47-millimeter intake valves, with old graduation. Also, UMP 417 got a carburetor into two cameras and a new air filter. Later in these engines began to use crankshaft without stuffing.

If you compare UMP 417 with ZMZ 402, then their differences will be cosmetic: in 417 there are no ribs of stiffness, the sleeves are more gently planted, and the flywheel has a larger size, while the principle of operation of the cooling system is inverted.

Other intake manifold and smaller outlet valves are reflected in the power of the motor.

The engine malfunction is completely similar to the minuses of the ZMZ 402, that is, there are extraneous noise and knocks, the need to adjust the valves every 10 thousand kilometers, overheating, and so on.

Vibrations and twigs arise due to the design curve, as a result of which the fuel is applied unevenly.

Experts consider the engine UMP 417 obsolete, as well as the remaining aggregates from the GAZ-21 family and under the hood modern cars They are not a place. one

Engine UMP 421/4213/4215/4216/4218 2.9 l

The power unit UMP 421 became the most modern modification of the gas-21 engine and the logical development of the model UMP-217, but with a large volume, increased to 39 mm release valves. In the newest versions of UMP 421 already installed injector fuel supply system.

The engine UMP 421 differs from ZMZ 402 with thin dry sleeves, which increased the strength of the block, with a 100 mm cylinder in diameter, and fingers are shifted into 7 mm in pistons. Instead of anachronic packing, rubber cuffs and other small spare parts are used.

At the same time, on a global scale, the engine has not changed and in essence it is the same unit of the mid-50s, but in an improved form.

Due to the lack of hydraulic components, every 10,000 kilometers will have to adjust the gaps.

The disadvantages of UMP 421 include a curve structure that affects the occurrence of twigs, vibrations and other things.

A knock in the engine occurs due to non-regulated valves, connecting rod liners or camshafts.

Overheating of the motor arises due to the defect of the thermostat, pump or air traffic jam in the cooling system.

The advantages of UMP 421 include the traction, accessibility of spare parts and complete maintainability. If the engine care and not overload it, then the resource will be at least 200 thousand kilometers.

Engine ZMZ 409.10 / 4091.10 / 4092.10 / 4094.10 2.7

Base for more bias engine ZMZ.-409 served as ZMZ-405, in which the crankshaft was used with an increased up to 94 mm move, the former rods, altered pistons shifted by 4 mm. And otherwise it is all the same 405th with the same height of the cylinder block, thinner inter-cylinder jumpers, slots for cooling. The torque increased due to the performance grew by 7 "horses", and the latest modifications of the engine correspond to Euro-3 eco-standards.

The malfunctions are calculated to jam the HD timing chain, but the valve is not bent.

In the overheating of the engine, the thermostat is guilty or a cloud radiator.

Falling the thrust is the "work of the hands" of the ignition coils, which must be replaced otherwise the engine will break.

The knocks arise due to the hydrocompensator that requires replacement.

Candles, connecting rod liners and compression are affected on the engine trim.

UMP 417 - engine, which was specially created for SUVs, which produced Ulyanovsk Automobile Plant: UAZ-469 and UAZ-452. This unit came to replace the motor 414th model.

Engine General Information

The engine UMW-417 (photo below) has a classic vertical, in-line location of the cylinder group. By type, the motor belongs to four-stroke installations with carburetor forced system Fuel supply. Motor cooling is also organized traditionally for DVS and is closed loopfilled with liquid, the circulation of which is ensured by a special pump. Motor oil The assemblies of the unit are fed under pressure, with further splashing.

Engine features in comparison with predecessors

First of all, it is necessary to note the fact that the engine of the 417th model, which UAZ began to produce in 1989, is an almost analogous to the power unit from the Volga region - ZMZ-402, which began in 1981. It is installed on cars of the Volga and Gazelle series. And the differences of one from each other are not too significant.

Therefore, to say that UMNs-417 received a completely new GBC, in comparison with UMP-414, it is possible only with a large stretch, as it is similar to the ZMZ-402 head, but in comparison with the "old" UAZ engine, the compression ratio has increased from 6 7 to 7.

The actual changes touched the gas distribution mechanism. First of all, a new camshaft and the output valve were installed (the diameter of the Hat with 44 mm increased to 47 mm), the inlet remained the same (36 mm). In addition, the form of the exhaust manifold was changed, which was now a scheme 4-1, that is, four pipes from cylinders converged in one.

The block itself is cast from aluminum, the sleeves are made of cast iron. In the engine of the 417th models, they are planted through gaskets made of oil resistant rubber - this is one of the weak points of this motor, as the total strength of the block is reduced. By the way, ZMZ-402 laying on copper sleeves. In addition, the umz-417 early releases did not provide the ribs of rigidity, they appeared later.

Another difference of UMS from ZMZ is that there is a special fastening under the VAZ oil filter on the case (VAZ-2101).

Crank I. distributional trees, pistons with rings, valve pushers and rods at the engine of the 417th model are the same as on ZMZ-402. The cylinder sleeves differ from them, as the landing due to gaskets is different. The flywheel at the engine UMS is larger in diameter and heavier in weight, the bell, respectively, also has increased dimensions.

Another weakness The engine is a padding: if it is laid in special grooves in the cylinder block and the crankshaft lid, then it is screwed to the axis on the axis and on top of the steel plates, which reduces the tightness of the joint.

Engine UMW-417: Ownership Reviews

If you analyze the reviews of Owners owners, on which the 417th engine is installed, then in general they note the unique reliability of the unit. The motor can maintain performance even after strong overheating. Its real working resource significantly exceeds the factory declared by the factory, while the engine is unpretentious and can work quite normally and bad gasoline, and on low-quality oil.

But there are disadvantages:

• If the engine ZMZ water pump downloads antifreeze into the cylinder block, and selects from the CLP, then in UMS and the feed, and the selection occurs from the head, as a result, the engine is cooled uneven and often overheats.
• Since the exhaust manifold is made according to Scheme 4-1, then the engine on medium and high speeds, which is said, "does not pull".
• For the stated power too big flow Gasoline.
• Looking for oil through leakage compounds, and even through the unit itself (the low quality casting of the housing, leading to the creation of large pores, leads to the formation of microchannels through which the oil can fall both outside and in the coolant).
• Lack of high-quality spare parts.
• The need to adjust the thermal gaps in the valves.

UMS-4178.10. - Designed for the UAZ line. To upgrade, it used the head of the unit from UMS-421, and the asbestos and crankshaft packs were replaced with the gland.

Engine maintenance

It is known that timely engine maintenance allows you to significantly increase its working resource. Therefore, the oil in the motor to extend his life should be changed every 10 thousand km. In the crankcase and the oil radiator, 5.8 liters are included, the exhaustable residue at the subsequent shift is 0.5-1 liters. Along with the oil, the filter changes (suitable from VAZ-2101).

The adjustment of thermal gaps on the valves should be carried out after passing every 15 thousand km.

Motor malfunction and repair 469 / loaf UMZ-417

Motor UMW-417 The next step in the evolution of the GAZ-21 motor, replaced the Motor UMW-414, which differs in an increased degree of compression from 6.7 to 7, another camshaft, enlarged inlet valves Up to 47mm (was 44mm), graduation old 36mm, a two-chamber carburetor was installed, another air filter. In later modifications, the crankshaft from UMP-421 was used without packing.
Comparing our engine with a 402 engine from ZMZ, it becomes clear that these are absolutely the same motors and their differences are very cosmetic: on the first 417th blocks there are no ribs, the sleeves are not so tough, the flywheel is more than 402th, the principle of operation of the system Cooling put upside down. Differences in power are caused by another exhaust collector and exhaust valves of smaller diameter (36mm, versus 39 mm), in the last edition of the motor, the valves use 39mm. On this, more less important differences are completed.

Motor modifications UMP 417

1. UMS 417.10 is the main motor, compression ratio of 7 under 76 gasoline. Power 92 hp Compliance with the environmental requirements of Euro-1. Designed for cars UAZ.
2. UMS 4175.10 - analogue UMP 417.10. The degree of compression 8.2 under 92 gasoline. Power 98 hp Used on cars Gazelle.
3. UMP 4178.10 - analogue UMP 417.10, a collector for a two-chamber carburetor. Used on UAZ cars.
4. UMP 4178.10-10 - analogue UMP 4178.10, GBC from UMP-421 with increased exhaust valves up to 39mm. Used gland instead of packing. Pomp on block. The motor is applied on UAZ vehicles.

Engine malfunctions UMP 417

In terms of problems and malfunctions, the motor is 100% similar to ZMZ-402. Vibration, jerking, overheating, knocks, valve adjustment every 10,000 km and many other charms have not been going anywhere and wait for you. Motor problems in detailwe read.
Summing up, UMNS-417 is the same old design, like all other relatives of the 21st Volga motor, including the 417-go changer - UMP-421.

Atmospheric Umz 417.

Options How to enlarge the power of the engine UMP-417 carbureau is not so much, but something can be done. First, it is necessary to delete the CPG and the crankshaft with the flywheel, put the head from the 421th motor, or at the standard increase the compression ratio to 8.2 under 92 gasoline, taking the cylinder head to the height of 95mm. The camshaft of the OKB engine or the like, for the upper motor, you need a shaft with a phase sewing (too wide shaft take pointless because SPGs are too heavy for high revolutions), I need the bottom, respectively, we put the narrow-phase. Exact graduate channels to 39mm and put the valves from UMP-421. We install the exhaust manifold from 421 engine, the exhaust pipe with a diameter of 51mm. Result to all transformations we get a little more than 100 hp. To increase the return to 110 and more hp, you need to do the GBC porting, grind the combustion chambers, point the channels, alleviate heavy tractor piston, crankshaft, balance, milling the head to a height of 94mm at 95 gasoline. Next to raise nowhere, the turbocharger without alterations to the injection will not rise, the alteration is inadequately expensive and cheaper to put injector UCM-421 initially. The turbine UMW-417 with wet sleeves is unsafe, the motor is too harpky and will not survive the pressure. For chapter, at a minimum, you need a 421th engine with pressed sleeves.

On old cars UAZ Buanka and 469 installed 417 engine. This engine has won folk recognition due to the simplicity of the design and good technical characteristics. Large differences from the 402rd ZMZ motor do not exist.

Specifications

As mentioned earlier, the engine 417 on the UAZ from the Ulyanovsk engine plant was almost the same with ZMZ 402. To be more accurate, the main design was copied, and the UMN only made some cosmetic amendments.

To improve the work on the UAZ and the motor adaptation, the flywheel, the release system and the exhaust valve were redested. This is the optimization and modernization of the engine ended.

Consider the main specifications 417 Engine UAZ:

In addition to the original motor, the world saw several modifications:

1. UMS 417.10 is the main motor, compression ratio of 7 under 76 gasoline. Power 92 hp Compliance with the environmental requirements of Euro-1. Designed for cars UAZ.
2. UMS 4175.10 - analogue UMP 417.10. The degree of compression 8.2 under 92 gasoline. Power 98 hp Used on cars Gazelle.
3. UMP 4178.10 - analogue UMP 417.10, a collector for a two-chamber carburetor. Used on UAZ cars.
4. UMP 4178.10-10 - analogue UMP 4178.10, CFC from UMP-421 with increased outlet valves up to 39mm. Used gland instead of packing. Pomp on block. The motor is applied on UAZ vehicles.

Service

It is easy to serve the engine. So, planned service maintenance It is held every 15,000 km. This includes the replacement of oil and filter. To replace the oil, you have to unscrew the drain plug and wait until it fits lubricant. Then, the plug is tightened, and the oil is poured through the bay neck. Oil filter Changes when there is no oil in the motor.

also in maintenance Includes checking all systems, no heights of oil and malfunction. Every 30,000 km must be adjusted by valves, and every 20,000 km is made to replace the air filtering element.

Malfunctions and repair

The main faults of the 417th DVS, exactly the same as in the ZMZ-th 402. Consider, with which major problems will have to face motorists in the process of operation of the UMS-th power unit:

1. The main problem becomes a seaside packing, which is installed instead of the rear seal of the crankshaft. Often, from under the part begins to flow, due to the softening of the product.
2. The unfinished injection design makes an uneven fuel injection, because of this often disappear idlingAnd vibration appears.
3. Frequent adjustment of the valve mechanism. If you do not carry out the process on time, but after 15,000 km of run, then a metal knock appears in the engine.
4. Eternal problems with thermostat and overheating. This mono problem is solved in two ways. First, to establish a quality product of imported production. The second way, withdraw the thermostat outside from the block and install from the Vase "Classics".

Repair of the UAZ 417 engine is carried out by analogy with ZMZ 402, since it is a constructive copy. Motor 417 is fairly easy to repair even in the worst technical condition. Thus, a power unit is carried out, the block head and replacing the consumables. The repair process itself is carried out in stages, as for any power unit. So, consider the main positions of capital repair umz 417.

Disassembly

At this stage, DVS is completely disassembled, namely the block head is dismantled, the pallet is removed and all parts are disassembled. For this type of motors, the defect process is carried out in the disassembly process. This does not include only the bloc of the cylinder block, the crimping of the head, as well as the kneading shaft.

Diagnostic operations

At this stage, work is carried out to determine the hardness and thickness of the crankshaft neck, as well as its maintainability. So, if the item can be repaired, then the size of the neck and the product is reduced to the subsequent processing. The same is waiting for the cylinder block. The sleeves are measured, and the repair size of the pistons is determined.

Covering GBC 417 is the process of determining the presence of cracks in the housing. All holes are closed on the head, in addition to the intake for the coolant, which serves hot water or kerosene.

Further, the specialist looks, is there any tricks and cracks. If not, the GBC goes to repair, and if there is, then all defects need to be brewed. Since the part is made with aluminum, argon welding is used.

IN garage conditions, To close the holes in the case of the power unit, motorists use cold welding.

Boring

The cylinder block and crankshaft are subjected to boring. If the cylinders have already come out from the repair size, then the sleeves of the standard diameter of 92 mm are installed. Honinovka is characteristic of the cylinder block, this is one of the processes of the block of cylinders of the block using a special machine. Crankshaft It is mounted on a special unit, with high revolutions and stone, which polishes cervix.

Work on the GBC.

The head of the cylinder block is also leaving the bulkhead. So, the valve, saddles, glads and cuffs are often changing. Repeatedly experts have to replace the valve guide sleeves. With development modern technology Repair, for ZMZ 402, you can apply the K-Line gels. For this, bronze sleeves are 9 mm in size.

To date, it is often found to replace the camshaft. This is due to the fact that the engines for 20-30 years and this item has been worn out several times. Therefore, when conducting repair GBC It is worth paying for this item. special attention. If necessary, the work surface of the block head is polished.

Assembly

Assembly operations are carried out on a special bench. All items are installed in the same sequence as they understood. So, the replacement, often, is amenable to oil and water pump, a new set of gaskets is installed.

Output

Motor UMP 417 on UAZ is an original copy of the ZMZ 402, and, accordingly, is a powerful and reliable power unit. Like any motor, this one has a number of flaws that can be easily corrected using refinement and tuning.
