417 UAZ engine: specifications, repair, photo

Most of the engines installed on cars and trucks are designed for long-term operation. At the same time, designers envisaged the possibility of overhaul, usually not even one, but several. For this, there are special repair dimensions of parts. But now I would like to talk about the features of a particular engine, its maintenance and operation. It's about the 417th UAZ engine, which is considered to be the most popular and universal.

Some general information

It is worth noting that the engines for UAZ vehicles were manufactured at the Ulyanovsk and Zavolzhsky motor plants. If we talk about the 417th, then this is the power unit produced by UMP. This is a in-line 4-carburetor type. This petrol engine first appeared in 1989 and is produced in our time. The head of the block is made of aluminum. This made the power unit more lightweight, but at the same time more vulnerable to overheating. Many of the same motorists, who happened to ride on UAZ, praise the 417th motor. It is spoken of as a powerful and durable, as well as durable ICE.

In addition, its design is simple enough, so the 417th is very maintainable, which is extremely important. In any case, reviews about the 417th UAZ engine are positive, and this already speaks volumes. Well, now let's go further.

Engine Specification 417 UAZ

At one time, the appearance of the 417th could be called a kind of breakthrough. It replaced the morally obsolete UMZ 414. The latter was already considered to be not the best in the 1970s, which is already talking about the late 80's, when more advanced power units appeared. UMP 417 compared to 414 had enlarged valves, as well as an entirely new air filter.

It is hardly necessary to say that the other technical characteristics were on a completely different level. Currently, four modifications of the motor are produced, each of which is used for certain purposes:

• 417.10 - is installed on the UAZ "Patriot" and "Hunter". Power of the power unit 92 horsepower, uses 76-m gasoline;
• 4175.10 - is installed on the "Gazelle". This modification has 98 hp. And uses 92-m gasoline;
• 4178.10 and 4178.10-10 - are installed on many UAZ cars and are, in fact, similar power units.

The working volume of the engine is 2.4 liters, while the power is 92 liters. from. At 4,000 rpm. The motor resource of such an engine is about 150,000 kilometers, but in practice it can be either larger or substantially smaller. So we reviewed the technical characteristics of the UAZ 417 engine, now we go further.

On the weak places of the motor

Despite the high reliability, this ICE had many weak points. As already noted above, it was made of aluminum. Its weight was only 166 kilograms, which is not so much for such a power unit. But at the same time, there was a problem with overheating. Exceeding the permissible temperature led to cracks in the block, violations of the geometry of the head and other problems. Very often there are vibrations at idle and under load. But the most serious problem is the appearance of a knock.

All these violations are associated with the wear of individual parts, such as cams, bearings, springs, etc. In some cases, there is a lack of maintenance: failure to comply with the time limits for replacing oil, coolant, etc. All this leads to a deterioration in the engine condition. In the end, he can jam. But even if this does not happen, its resource will significantly decrease. This characteristic of the UAZ 417 engine, like compression, will fall, it will start to eat oil, and major repairs will be required.

About restoration УМЗ 417

It's one thing to repair an imported engine, where almost all the spare parts have to be ordered from behind the mound, which is quite expensive and costly. As for the 417th, it is much easier to repair it. It is a domestic motor of simple design, which is known to almost all specialists. Although many do not bother, but simply take and put on UAZ a new power unit, in some cases it makes sense to tackle the old one.

If you do the work yourself, then you will take about 20,000 rubles for spare parts. In the case of repair in SRT add about the same for the work. But even with this approach it is not so expensive, in comparison with some foreign cars, where repairs of ICEs cost hundreds of thousands.

Expert reviews about the engine UAZ 417 (UMP)

The first and most basic thing that many drivers and experts distinguish is excellent traction. But much depends on the carburetor. In the latest modifications, injector injection systems are already being installed, but now it's not about them. Many experts recommend installing Solex. With it, and the thrust increases, and the consumption is significantly reduced. But this is compared with the K121, which, though old, is used quite often. Many stop at K151, as, according to the majority, it is the best for the UAZ 417 engine. Which carburetor should I put? It's up to you.

Experts recommend changing the oil in the system every 10 thousand kilometers. Pour about 5.8 liters, while not forgetting the type and brand of lubricant. All this information is indicated in the instruction manual.

Typical problems and ways to eliminate them

Each engine has weak points, which are inherent only to him. So it happened with the 417th. This motor breaks down though and not often, but delivers a lot of problems to its owner. Usually everything starts with an oil leak. Leaks occur for various reasons, from the developed seals and gaskets and to breach the tightness in the system. Usually these problems are simply eliminated. Seals and gaskets change, the old sealant, if necessary, is removed and a new one is poured.

In general, almost all problems with the 417-m are associated with lubrication. That level is too big, then too low, then the oil leaves because of a leak or burns in the chamber. All these problems are solved, but it is necessary to do this as soon as possible. The faster the UAZ 417 engine is repaired, the photo of which you can see in this article, the more the motor will live.

Increased wear of internal combustion engine

Wear is one of the most pressing problems, which has almost nothing to do with the design features of the power unit. The key factor affecting increased wear is the low quality of the lubricant or its insufficient quantity. Undoubtedly, if you do not change oil once through 10 thousand kilometers, and you do it in 15 days, nothing terrible will happen. But if you do so regularly and do not follow the level, pouring the cheapest grease, the consequences will be the most sad.

It often happens that a minor flaw in the operation of the power unit develops into a major overhaul. That is why, the sooner the driver begins to solve the problem, the less will be the cost of repairs.

Maintenance of engine systems

It must be understood that the engine of the car needs periodic maintenance. This is the replacement of oil and filter elements, installation of new spark plugs, replacement of rollers and belt or chain timing. All this must be done to ensure that your engine works smoothly for a long time. If the first prerequisites for repair have appeared, then it is necessary to take measures as soon as possible. In total there are three stages of restoration of the 417th:

• Repair in the field is a temporary measure that is taken to get to the destination;
• Selective repair (partial) - includes disassembly of the motor and defect of parts;
• Major repairs - a complete restoration of the engine regardless of its condition. This is a rather laborious process, requiring a lot of knowledge and patience.

Many drivers install a UAZ engine - an injector. The electronic injection system deprives the car of the carburetor's faults. If there is no desire to do alterations, then it is possible to put systems from 4213 and 4216, which stand completely without rework. The only thing you need to do is to calibrate the firmware.

Replacing the 417th with another motor

Many motorists have thought about this. In fact, such a procedure is usually necessary in the event that the 417th has completely developed its resource and it does not make any sense to capitalize it. In this case, you can put another engine, more reliable and cheaper. To such it is necessary to carry ZMZ-402. It, in the opinion of many experienced motorists, is more reliable than UMP, and cheap in service. In addition, it's much easier to find a live 402 at a relatively lower price than the 417th and this is a big plus.

Of course, many will perform the replacement only if it is financially profitable. That's why it is recommended to put the engine ZMZ-402. It fits almost without rework. All fastenings will be in their place, so the costs will be minimal. Some motorists on their UAZ are installing imported engines from Toyota and other cars. Usually diesel engines are put. This, of course, everything is fine, the sensations are changing completely, but such a pleasure is not cheap, because the design makes a lot of changes.

Let's sum up the results

So we reviewed the main technical characteristics and features of the engine 417 on UAZ. How many horses give out such a power unit? If the classical version, then 92 liters. from. This is usually more than enough. But the power, due to certain alterations, can be slightly increased. It is worth doing this or not, each for himself decides for himself.

In general, the 417th can be called a very successful creation of the Ulyanovsk plant. After all, modifications of this engine were developed, which later found wide application not only on UAZ vehicles, but also on Gazelle. This engine has its drawbacks. Some of them can be eliminated in the field, others require professional intervention. But on the way this engine is extremely rare, so it can be called reliable. Another thing is that a resource of 150,000 kilometers is not so much. I would like to see the figure a little higher, at least 250 thousand. But with careful maintenance and gentle operation, 417 can run and more than written by the manufacturer.
