Most of the engines installed on cars and trucks are designed for long-term operation. At the same time, the designers provided for the possibility of major repairs, 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 motor, its maintenance and operation. It will be about the 417th UAZ engine, which is rightfully considered 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 engine plants. If we talk about the 417th, then this is the power unit produced by UMP. This is a inline 4 carburetor type. This gasoline ICE first appeared in 1989 and is produced nowadays. The block head is made of aluminum. This made the power unit lighter, but at the same time more vulnerable to overheating. Many motorists who happened to drive in an UAZ praise the 417th engine. He is spoken of as a powerful and enduring, 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 already in the 70s was considered not the best, what to speak of 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 other technical characteristics were at a completely different level. There are currently 4 modifications of the motor, each of which is used for specific purposes:
- 417.10 - installed on the UAZ "Patriot" and "Hunter". The power of the power unit is 92 horsepower, uses 76th gasoline;
- 4175.10 - installed on the "Gazelle". This modification has 98 hp and uses 92nd gasoline;
- 4178.10 and 4178.10-10 - are installed on many UAZ vehicles and are, in fact, similar to power units.
The engine displacement is 2.4 liters, while the power is 92 liters. from. at 4,000 rpm The engine life of such an engine is approximately 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 move on.
About the weaknesses of the motor
Despite the 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 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: non-observance of the deadlines for changing the oil, coolant, etc. All this leads to deterioration of the condition of the engine. He may eventually jam. 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 major repairs will be required.
About the restoration of UMP 417
It is one thing to repair an imported engine, where almost all parts have to be ordered from behind a hill, which is quite expensive and expensive. As for the 417th, it is much easier to repair it. This 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 a UAZ a new power unit, in some cases it makes sense to tackle the old one.
If you perform the work yourself, then it will take you about 20,000 rubles for parts. In case of repair at the service station, we add about the same for the work. But even with this approach, it is not so expensive compared to some foreign cars, where the repair of ICE costs hundreds of thousands.
Expert reviews on the UAZ 417 engine (UMP)
The first and most basic thing that many drivers and experts highlight is excellent traction. But a lot depends on the carburetor. In the latest modifications, injection systems are already installed, but now it's not about them. Many experts recommend installing Solex. With it, thrust increases and consumption decreases significantly. But this is when compared with K121, which, although old, is used quite often. Many people stop at K151, since, according to most, it is he who is best suited for the UAZ 417. Which carburetor should I put? It is 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 not forgetting the type and brand of lubricant. All this information is indicated in the instruction manual.
Typical problems and solutions
Each engine has weaknesses that are unique to it. So it happened with the 417th. This motor breaks, though not often, but causes a lot of problems to its owner. Usually it all starts with an oil leak. Smudges appear for a variety of reasons, from exhaust gaskets and gaskets to leakage in the system. These problems are usually resolved simply. Glands and gaskets are changed, the old sealant is removed if necessary and a new one is filled.
In general, almost all problems with the 417th are associated with lubrication. Either the level is too high, then too low, the oil leaves due to a leak or burns out in the chamber. All these problems are solvable, but you must do this as soon as possible. The faster the repair of the UAZ 417 engine is completed, the photo of which you can see in this article, the more the motor will live.
Increased engine wear
Depreciation is one of the most pressing problems, which is almost completely unrelated to the design features of the power unit. A key factor affecting increased wear is the poor quality or lack of lubricant. Of course, if you do not change the oil once after 10 thousand kilometers, but do it after 15, then nothing bad will happen. But if you do this on a regular basis and at the same time do not monitor the level, filling in the cheapest lubricant, then the consequences will be 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 lower the repair costs will be.
Engine Service
You need to understand that the 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 so that your motor runs smoothly for a long time. If the first prerequisites for repair have appeared, then it is necessary to take measures as soon as possible. There are three stages of restoration of the 417th:
- field repair - a temporary measure that is taken in order to reach the destination;
- selective repair (partial) - includes disassembling the motor and troubleshooting parts;
- major repairs - full restoration of the engine, regardless of its condition. This is a rather time-consuming process, requiring a lot of knowledge and patience.
Many drivers install on the 417 UAZ engine an injector. An electronic injection system robs the car of carburetor flaws. If there is no desire to do alterations, then you can put systems from 4213 and 4216, which stand up completely without alterations. The only thing to do is 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 there is no sense in capitalizing it. In this case, you can put another engine, more reliable and cheaper. These include the ZMZ-402. He, according to many experienced motorists, is more reliable than UMP, and cheaper to maintain. In addition, it is much easier to find a live 402nd at a relatively low price than the 417th and this is a big plus.
Of course, many will perform the replacement only if it is financially profitable. That is why it is recommended to install the ZMZ-402 motor. It fits almost without alterations. All fasteners will be in place, so the cost 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 a pleasure is not cheap, because a lot of changes are made to the design.
To summarize
So we examined the main technical characteristics and features of the 417 engine in the UAZ. How many horses does this powertrain produce? If the classic version, then 92 liters. from. This is usually more than enough. But power, due to certain alterations, can be slightly increased. Whether or not to do this, everyone decides for himself.
In general, the 417th can be called a very successful creation of the Ulyanovsk plant. It’s not just that modifications of this engine were developed, which later became widely used not only on UAZ vehicles, but also on the Gazelle. This engine has its drawbacks. Some of them can be eliminated in the field, others require professional intervention. But on the road, 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 even more than it is written by the manufacturer.
