Most of the engines installed in cars and trucks are designed for long-term operation. At the same time, the designers provided for the possibility of a major overhaul, usually not even one, but several. For this, there are special repair sizes of parts. But now I would like to talk about the features of a particular motor, its maintenance and operation. We are talking about the 417th UAZ engine, which is rightfully considered the most popular and versatile.

Some general information

It is worth noting that engines for UAZ vehicles were manufactured at the Ulyanovsk and Zavolzhsky motor plants. If we talk about the 417th, then this is a power unit manufactured by UMP. This is an in-line 4-ka carburetor type. This gasoline ICE first appeared in 1989 and is produced in our time. The block head is made of aluminium. This made the power unit lighter, but at the same time more vulnerable to overheating. Many motorists who had a chance to drive a UAZ praise the 417th engine. They talk about it as a powerful and hardy, as well as durable ICE.

In addition, its design is quite simple, so the 417th is very maintainable, which is extremely important. In any case, the reviews about the 417th UAZ engine are positive, and this already says a lot. Well, now let's move on.

Technical characteristics of the engine 417 UAZ

At one time, the appearance of the 417th could be called a kind of breakthrough. It replaced the obsolete UMP 414. The latter was already considered not the best in the 70s, let alone the late 80s, when more advanced power units appeared. UMP 417 compared to 414 had enlarged valves, as well as a completely new air filter.

It is hardly necessary to say that the rest of the specifications were on a completely different level. Currently, 4 motor modifications are being produced, each of which is used for specific purposes:

• 417.10 - installed on the UAZ "Patriot" and "Hunter". Power unit 92 horsepower, uses 76th gasoline;
• 4175.10 - 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 vehicles and are, in fact,similar powertrains.

The engine capacity is 2.4 liters, while the power is 92 liters. With. at 4,000 rpm The motor resource of such a motor is approximately 150,000 kilometers, but in practice it can be either more or significantly less. So we examined the technical characteristics of the UAZ 417 engine, now we move on.

About the weak points of the motor

Despite its high reliability, this ICE had many weaknesses. As 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 knocking.

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 scheduled deadlines for changing oil, coolant, etc. All this leads to deterioration of the engine. Eventually, he may get stuck. But even if this does not happen, its resource will be significantly reduced. Such a characteristic of the UAZ 417 engine as compression will fall, it will start to eat oil, and a major overhaul will be required.

On the restoration of UMP 417

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

If you do the work yourself, then you will need about 20,000 rubles for spare parts. In the case of repairs at the service station, we add about the same amount for work. But even with this approach, it is not so expensive, compared to some foreign cars, where ICE repairs cost hundreds of thousands.

Expert reviews about the UAZ 417 (UMZ) engine

The first and most important thing that many drivers and experts point out is excellent traction. But a lot depends on the carburetor. In the latest modifications, injection injection systems are already being installed, but now we are not talking about them. Many experts recommend installing Solex. With it, and traction increases, and consumption is significantly reduced. But this is when compared with K121, which, although old, is used quite often. Many people stop at K151, since, according to the majority, it is he who is best suited for the UAZ 417 engine. Which carburetor to put? It's up to you to decide.

Experts recommend changing the oil in the system every 10 thousand kilometers. You need to fill in about 5.8 liters, while you should not forget about the type and brand of lubricant. All this information is indicated in the instruction manual.

Characteristicproblems and solutions

Each engine has weaknesses that are unique to it. So it happened with the 417th. This motor breaks down, though not often, but it gives a lot of problems to its owner. It usually starts with an oil leak. Leaks appear for various reasons, from worn out oil seals and gaskets to leakage in the system. Usually these problems are easily fixed. Oil seals and gaskets are changed, the old sealant is removed if necessary and a new one is poured.

In general, almost all problems with the 417th are connected with lubrication. Either the level is too high, or it is too low, or the oil leaves due to a leak or burns out in the chamber. All these problems are solvable, but it is necessary to do it as soon as possible. The faster the UAZ 417 engine is repaired, the photo of which you can see in this article, the longer the engine will live.

Increased ICE wear

Wear is one of the most pressing problems, which has almost nothing to do with the design features of the power unit. A key factor influencing increased wear is poor quality or insufficient lubricant. Of course, if you don’t change the oil once after 10 thousand kilometers, but do it after 15, then nothing bad will happen. But if you do this regularly and at the same time do not monitor the level, filling in the cheapest lubricant, then the consequences will be the saddest.

It often happens that a minor flaw in the operation of the power unit develops intooverhaul. That is why, the sooner the driver begins to solve the problem, the lower the repair costs will be.

Engine systems service

You need to understand that a car engine needs periodic maintenance. This is the replacement of oil and filter elements, the installation of new spark plugs, the replacement of rollers and a belt or timing chain. All this must be done to ensure that your motor runs smoothly for a long time. If the first prerequisites for repair have appeared, then it is necessary to take action as soon as possible. There are three stages in the restoration of the 417th:

• Field repairs are a temporary measure taken to get to the destination;
• selective repair (partial) - includes disassembly of the motor and troubleshooting of parts;
• overhaul - complete restoration of the engine, regardless of its condition. This is a rather time-consuming process that requires a lot of knowledge and patience.

Many drivers install a UAZ engine - an injector on the 417. The electronic injection system deprives the car of the disadvantages of the carburetor. If there is no desire to engage in alterations, then you can put systems from 4213 and 4216, which stand up completely without alterations. The only thing 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 needed if the 417th has completely exhausted its resource and capitalize it alreadydoesn't make sense. In this case, you can put another engine, more reliable and cheaper. These should include ZMZ-402. He, according to many experienced motorists, is more reliable than UMP, and cheap to maintain. In addition, it is much easier to find a live 402 at a relatively low price than a 417, and this is already a big plus.

Of course, many will only replace if it is financially profitable. That is why it is recommended to install the ZMZ-402 motor. It fits with virtually no modifications. All fasteners will fall into place, so the costs will be minimal. Some motorists install imported engines from Toyota and other cars on their UAZ. Usually diesel engines are installed. This, of course, is all good, the sensations change completely, but such pleasure is not cheap, because many changes are made to the design.

Summarize

So we looked at the main technical characteristics and features of the 417 engine on the UAZ. How many horses does such a power unit produce? If the classic version, then 92 liters. With. This is usually more than enough. But the power, due to certain alterations, can be slightly increased. It is worth doing it or not, everyone decides for himself.

In general, the 417th can be called a very successful creation of the Ulyanovsk plant. After all, it was not just that modifications of this motor were developed, which later found wide application not only on UAZ cars, but also on the Gazelle. This engine hastheir shortcomings. Some of them can be eliminated in the field, others require professional intervention. But on the way, this motor fails extremely rarely, 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, the 417 can run more than it is written by the manufacturer.
