A new injection pump pump costs the owner about 5.6 thousand dollars, spare parts for repair cost about 2 thousand, the work itself is about 350 dollars (dismantling, assembly, adjustment), and it will be done, by no means in any service center.
Both the naturally aspirated and turbocharged RD28T engines are in-line 6 cylinders. It has a volume of 2.8 liters, air is supplied to the combustion chambers in a vortex manner for a sharp increase in power. Throughout the history of the engine, the production volumes of atmospheric modifications did not exceed 50 pieces, they did not go into the series.
During the development of the RD28, the modernization of the previous versions was as follows:
Used factory boost by a turbocharger. Although the Nissan management positions the RD28 as a low-noise powertrain, it is still a diesel engine, the work of which in the cabin will be hidden only by high-quality noise isolation.
An important feature of the configuration is the Zexel fuel pump - at first the mechanical type was used, and for the last three years the electronically controlled version. On the belt there are marks of both the timing pulley and the injection pump, which facilitates do-it-yourself overhaul.
Cylinder head of atmospheric versions were labeled 1 and 2 (with hydraulic lifters), turbocharged 3 - 6. First, the vacuum pump was located on the generator, then the attachment was transferred to the head.
The turbocharged tuning of the RD28T engine leads to increased piston wear, which causes a decrease in compression.
VIDEO
Injection pump of a frankly weak design, in principle maintainable, in practice it is very difficult to find a specialist for disassembly, therefore 70% of the fleet of cars with this engine is difficult to start, they smoke heavily, but they still drive, although they drive oil.
The turbine costs $ 1400 new and $ 400 for disassembly, plus repairs of about $ 800 with replacement of the cartridge - in principle, the same money.
The weak point of the RD28 is the duralumin cylinder head:
a sudden rupture of the timing chain links leads to the piston meeting the valve;
The cylinder head is seriously injured, it has to be changed along with the ShPG.
Statistics show that the RD28 engine in all modifications ranks first in the number of overhauls. For the Patrol SUV, engine power is not enough, the executive Cedric with a rattling diesel engine has become a popular topic of jokes. For other classes of cars, it is recommended to use them without restrictions.
The termination of serial production of the manufacturer's plant is caused by the fact that Japanese companies have decided that only those modifications of turbocharged diesel engines that have atmospheric analogues will remain in the ICE lines. At that time, the QD32 and TD27 were produced by Nissan and met the specified conditions.
The disadvantage is the location of the air intake on the turbocharged and atmospheric RD28 engine, which is unsuccessful in terms of hydrodynamics. In addition to the likelihood of water hammer, the user receives additional costs, since the Safari snorkel costs one and a half times more than this unit on other Nissan diesel engines.
The ignition system uses a complex scheme:
a separate chain is created for every three cylinders;
the chain control unit is located under the wing of the machine;
exposed to atmospheric influences and burns out.
As a result, the candles either do not receive power or burn out from excess voltage. Each of them costs 1000 (third-party) or 1500 rubles (original), and you need 6 of them. For normal operation of the intercooler at low speeds, a fan is provided that turns on automatically when heat transfer deteriorates.
The timing belt costs from 4000 rubles, and the rollers are 2000 rubles, the work costs about the same amount. Replacement is recommended after 90,000 km, and the rear crankshaft oil seal is guaranteed to flow when a new disc or clutch kit is installed, so the cost of replacing it should be taken into account when planning the operating budget.
The basic version of the RD28 of the first series was mounted on Nissan cars in the following years:
Skyline R31 - 1985 - 1987;
Laurel C32-C34 1986-1993;
Gloria Y30 - Y32 - 1985 - 1993;
Crew K30 - 1993 - 1999.
The second series of internal combustion engines was used on the Laurel C35, Gloria Y33 and Cedric between 1993 and 1999. Later, the RD28T diesel engine was used to complete Nissan cars (year):
Cedric - 1991 - 1999;
Patrol onboard - 1994 - 1997;
Patrol GR I - 1988 - 1999;
Patrol Hardtop - 1986 - 1990;
Patrol Station Wagon - 1989 - 1995.
The engine characteristics allowed it to be equipped with an automatic gearbox, so the Safari Spirit Y61, a two-door version of an SUV, also moved on it.
Since the production of the RD28T engine was stopped back in 2004, the service life of modern motors exceeds at least 12 years.Which is physically impossible without adhering to the maintenance schedule below:
after 15,000 km of run, the engine oil is drained, a new lubricant and filter are used;
after 20,000 km, you need to adjust the valve clearances, buy new candles and a belt for attachments, clean the crankcase ventilation;
the period of 30,000 km is critical for the air filter;
the tank cap and the fuel filter pass about 40,000 km;
after 45,000 mileage, the coolant, pipes and hoses of this system are changed;
a timing belt is usually enough for 100,000 km.
The ICE device has a fairly simple design to ensure the maintainability of individual units.
The RD28 motor has several characteristic diseases for it:

An engine, rebuilt correctly and “by hand” (meaning the knowledge of what has been changed / polished / machined / honed / fenced / ground in /. All that is needed and even a little more) is always better than one that was bought during disassembly of an unknown unit. And there shouldn't be any "problematicity" in a self-rebuilt motor.
PS: Correct overhaul made by the right craftsman.

I bought my favorite u60 c RD28T in August 2007
But the engine was killed. in 2007 he went over from two dozen showdowns from Iv.Frankovsk - to Odessa.
None of the proposed ones gave a guarantee that after the purchase I would drive without problems. The cost of the engine with more or less appearance and compression is from 1600 USD. - without attachment, bare block with a head.
A year and a half I was looking for a normal minder.
Before me, this minder repaired the same RD28T. (Kiev prices - 150 UAH per hour)
In 2009, he turned off the engine, and behind it: a turbine, a high-pressure fuel pump, an air path, a new EGR valve, new injector nozzles, a new clutch, a restored heating system. total: 52000 UAH with spare parts and the work of minder subcontractors.
Now I ride 20,000 after repairs - I'm happy.
In conclusion, I want to say that in order to rely on capital, you first need to diagnose and, if necessary, repair all the engine's life support systems.

the head of the engine requires a reasonable operation of the car.
from overheating leads the head - we constantly monitor the oil pressure and the temperature of the cooling.

“” Long-liver RD28T appeared on cars of the 160th and 260th series. Then this motor became the main one for the Nissan Patrol Y60 of the European market (it was also equipped with the Y61 of the first years of production). The problems are the same everywhere: the cylinder head and a relatively weak injection pump, which requires a bulkhead after 300 thousand. The injection pump, however, is maintainable, but there are not so many places where it can be sorted out correctly. The cost of disassembling, assembling and adjusting the high-pressure fuel pump at the stand is $ 300–325, but you may need spare parts for up to ... 2000. However, a new high-pressure fuel pump assembly costs $ 5592! So many old cars don't start very well, they smoke, but they drive. The same applies to the turbine. As a rule, she nurses from 300 to 400 thousand. Moreover, unlike other cars, she can drive oil with might and main, but this will not be an indicator of her death. In this state, the turbine can survive 100 thousand, or even more. But you need to understand that death can come at any moment. A turbine costs about 400 dollars for dismantling, repair with replacement of a cartridge costs about 700-800.The new turbine will cost more than $ 1,400.
On the atmospheric RD28, the head problems are the same. Head cracks appear after overheating, but not necessarily immediately. The crack development process can take a month, or two, or three. The new head is expensive, 1200-1500 "green", and it is sold empty, and you have to buy additional valves and camshafts. On disassembly, heads cost from $ 600 to $ 800, and this is a pig in a poke. If the car was overheated and the head was immediately removed, then external signs may not be seen. You can buy a cylinder head from a working machine on disassembly, press it, and everything will go fine, but when you pull it out, the very cracks will appear. A contract engine is also not an option - there are practically no such engines in Japan, and if there is, then they are very expensive. Nissan Safari with such an engine was produced in the amount of several percent of the total production (mainly TD42 and TD42T went to the “home” market). Residents of the "pro-Japanese" city of Vladivostok generally hate this motor and do not understand how it can be driven. At the same time, the imported motors are scattered like hot cakes, and often in Moscow this engine can be bought cheaper than in the immediate vicinity of its historical homeland.
Replacing the timing belt and rollers on the RD28 is set by the plant with a mileage of 100 thousand kilometers, but service employees recommend changing them a little more often (after every 90 thousand). Naturally, we strongly recommend replacing the timing belt immediately after purchasing a used car. They will take $ 90 for the work, the original belt costs 1,200 rubles in the store and $ 75 at the dealer, and the rollers will cost you 1,500 rubles (original) or 1,000 rubles (non-original), while at the dealers they are twice as expensive. When removing the belt, it's worth looking at how the oil seals feel. In fact, they live long enough, and the need for replacement arises when the mileage is about 200 thousand kilometers. But this means that a ten-year-old car is likely to have these problems already. Oil seals are inexpensive, which cannot be said about the work of replacing them. So it makes sense to replace the front crankshaft oil seal when replacing the timing belt, and the rear oil seal when replacing the clutch for the first time.
All RD28T models have a very clever glow plug control system. One chain goes to three cylinders, and another to the other three. The block that controls all this is under the wing and often burns out. It ends with the fact that either the candles start to burn constantly and fail, or they do not turn on at all and the engine does not start well. Glow plugs are quite expensive (1,500 rubles for the "original" or 1,000 for the "non-original"), and, as you understand, you need six of them. There is another curious system on this motor: in order for the intercooler to work effectively at low speeds (for example, in off-roading), it is equipped with an electric fan, which automatically turns on in case of poor heat exchange.
And one more thing to remember: on the RD28 and RD28T, the air intake is not located in the most successful way, and it is quite easy to get a water hammer. Moreover, the Safari snorkel with RD28T costs one and a half times more than for another common diesel, TD42. ””

they are also its advantages: without cutting the front end, you can turn on the lowering; the pneumatic drive does not cause any special problems (usually); due to the electronic injection pump, smooth traction at all speeds, confident dynamics, does not smoke, due to the high-altitude compensator, it feels good in the mountains; there is a five-door version with a good trunk; the cheapest spare parts are from Toyota

I have 61 on the box, RD28ETi:
They write about overheating - but I have not come across this.
In connection with the above, I would like to hear from the one who actually installed and operates the RD28 at the UAZ, their opinion, conclusions, and features of the engine installation.
Hi Rusan.
This ICE was used in large Nissan sedans such as Skyline, Laurel, Gloria, Cedric. On Safari, this ICE is more of a misunderstanding. An offer for buyers who wanted a replica of the Rallyraid car, but were not willing to pay for a large motor. This Safari was called the Safari Spirit (3-door version). Nissan's Spirit prefix is used for cheaper versions of the car. (For example Laurel Spirit is Sunny in slightly different optics)
RD28 ceased to be produced in 97, but not because it was unsuccessful, at that time all Japanese automakers curtailed their passenger diesel programs and left in their lines only turbodiesels that have atmospheric counterparts used in trucks and other commercial vehicles. (For example, Toyota - 2L, 3L, 5L, 2C, 3C, Nissan - TD27, QD32, MMC - 4D56,4M40, Suzuki / Mazda - R1, R2, RF, WL)
I drove cars from Japan for several years and tried different diesel engines in different ones. states.From my own experience, I can say that it is quite difficult to find the above motors in good condition, because this is mainly a commercial technique and it should pay off, so they have large runs and, accordingly, the state leaves much to be desired. In addition, buyers from third world countries, such as Pakistan, where import duties on foreign cars are very good. small, keep a high price for such cars. There are other important objective reasons as well. The RD28 has a clear advantage - a rear-wheel drive classic with a diesel unit is not in any demand from them, and the Japanese themselves buy such cars only for personal use while driving very well. few. Therefore, it is not difficult to buy such a motor in good condition with low mileage.
We have RD28 in good condition, too, very good. it is difficult to buy, since there are very few fans of rear-wheel drive cars with a diesel engine and cars in Japan are bought for analysis solely because of the bodywork with dead engines (they are cheaper). The motor is outboard, so that the duty is not paid, or for spare parts if there were orders. Those who drive, manage with minor repairs, rarely when you have to change the internal combustion engine.
Regarding the negative reviews on the RB28 forums, this is somewhat biased. Forums on motors gather mainly people who have problems with internal combustion engines and they try to solve them by exchanging information. Those who have everything in order, drive without problems and do not create branches like “what is my clear engine”. So negative reviews about any internal combustion engine can be found on any forum.
For example, if you read the forums on the 4D56 internal combustion engine with two balancing shafts and several timing belts, installed at one time on the MMC Delica StarWagon and MMC Pajero. So the impression is that there is no shitty engine in nature. However, it should be borne in mind that the largest volume of import of these cars to Russia fell at a time when in Japan and other countries this car was also in great demand and it was difficult to find a car in good condition at auctions, basically they got rid of cars with high mileage or killed when improper operation, etc. However, people in Russia who wanted to buy it were a shaft, so they were carrying almost corpses. As a result, all the car services are crammed with junk, on the forums hi, which dviglo shit. At the same time, time passed, the excitement subsided and it was possible to buy such a car for reasonable money in good condition, and so they still run (94-99 years of production) and there are no more problems with them than with all supposedly normal internal combustion engines. Moreover, 4D56 has been produced from the mid-80s to the present and is installed, for example, on Hyundai Galoper, Kia Sorento, Korando Family and some Japanese micro trucks.
The essence of the post - most of the reviews that RD28 is shit, on this forum I read from people who write that ”. I got this engine almost for nothing, I shoved it in, it turned out to be bad. ) "(You won't get a good internal combustion engine for nothing - that's clear.), Or, like". I found a piece of shit and put it in the car and it was really shit ”:)
By the way, if the cases of RD28 installation on UAZ are really known and if the engines on these UAZs, somehow very good. misbehaved. I think the owners of such a papodalov or artisan installers would have already checked in on the forum and crap the engine at least a couple of times. And then they drive somewhere on the sly, little by little, and they don’t fucking blurt out. When everything is good, people have no reason to shine on the forums, they have other interests.
So, if there is enthusiasm, try it.The only thing is, you will face difficulties, since apparently there is no information on the installation of such motors here. And you will be a pioneer. The RD28 internal combustion engine is the same as all diesel engines of its classmates and it should be compared with others at least in approximately the same ones. states. Many diesels come with aluminum heads, for example, Toyota 2C / 3C, Mazda WL, etc., as well as the famous 1KZ (developed by Yamaha for Toyota).
Good luck. I read some branches with pleasure. A lot of interesting. It's nice to read what people write with their hands and heads in place.
Over the long history, the Japanese carmaker "Nissan" has released a large number of truly high-quality units from its conveyors.
In the automotive industry, the company works in a rather diversified manner, creating both car models and various components for them.
ATTENTION! Tired of paying fines from cameras? A simple and reliable, and most importantly 100% legal, way has been found not to receive more “letters of happiness”. Read more"
Nissan ICEs have received the greatest recognition around the world. Today our resource would like to consider exactly one of the manufacturer's motors. Below you can read about the budget, but functional engine - RD28t.
The RD28t engine is a striking representative of power plants for SUVs and premium models produced by Nissan at the end of the last century. This ICE and its more powerful model were developed on the basis of the RD28 aspirated engine. The only significant differences between the new engine variations were the appearance of a turbine and a more thought-out design. Otherwise, RD28 and RD28t (RD28Ti) are completely identical.
What is the unit in question? It is a typical in-line diesel engine with good power. The RD28t is distinguished by the presence of a conventional (not promoted to maximum power) turbine, and the RD28Ti is, in fact, its modernized variation.
Interestingly, Nissan tried to popularize the naturally aspirated engine variation, but all attempts were unsuccessful. Today motors named "RD28t" or "RD28Ti" almost all run on diesel. It is almost impossible to meet their atmospheric counterpart (at least in the Russian Federation, the CIS countries and Europe).
The most widespread internal combustion engine in question received in the well-known to many - Nissan Patrol. The limited edition RD28t and its improved version were introduced into the Cedric and a number of other cars, but in this context, significant laurels were not found.
There are no significant features in the design and general principles of the construction of engines. They have a good volume of 2.8 liters, about a hundred "horses" and a typical diesel power system (OHC - gas distribution, injection pump - fuel). In principle, the development and serial production of the RD28t, RD28Ti can be considered quite successful. It is not for nothing that these diesel units have been produced for almost 25 years and have a considerable number of admirers all over the world.
Long-liver RD28T appeared on cars of the 160th and 260th series. Then this motor became the main one for the Nissan Patrol Y60 of the European market (it was also equipped with the Y61 of the first years of production). The problems are the same everywhere: the cylinder head and a relatively weak injection pump, which requires a bulkhead after 300 thousand. The injection pump, however, is maintainable, but there are not so many places where it can be sorted out correctly. The cost of disassembling, assembling and adjusting the high-pressure fuel pump at the stand is $ 300–325, but you may need spare parts for up to ... 2000. However, a new high-pressure fuel pump assembly costs $ 5592! So many old cars don't start very well, they smoke, but they drive. The same applies to the turbine. As a rule, she nurses from 300 to 400 thousand. Moreover, unlike other cars, she can drive oil with might and main, but this will not be an indicator of her death. In this state, the turbine can survive 100 thousand, or even more. But you need to understand that death can come at any moment. A turbine costs about 400 dollars for dismantling, repair with replacement of a cartridge costs about 700-800. The new turbine will cost more than $ 1,400.
On the atmospheric RD28, the head problems are the same. Head cracks appear after overheating, but not necessarily immediately. The crack development process can take a month, or two, or three. The new head is expensive, 1200-1500 "green", and it is sold empty, and you have to buy additional valves and camshafts. On disassembly, heads cost from $ 600 to $ 800, and this is a pig in a poke. If the car was overheated and the head was immediately removed, then external signs may not be seen. You can buy a cylinder head from a working machine on disassembly, press it, and everything will go fine, but when you pull it out, the very cracks will appear. A contract engine is also not an option - there are practically no such engines in Japan, and if there is, then they are very expensive.

So it makes sense to replace the front crankshaft oil seal when replacing the timing belt, and the rear oil seal when replacing the clutch for the first time.
All RD28T models have a very clever glow plug control system. One chain goes to three cylinders, and another to the other three. The block that controls all this is under the wing and often burns out.

candles zolhozili to me from the button. checked all work as well. the volume of crankcase gases was not measured. a little like a concept there is. operation 3st 8years.6ne1 years5 but with this I can’t give a fret. on hydrics, turns the starter suspiciously cheerfully in the cold and I can’t measure the clearances there were no hydrics even once.
Video (click to play).
After the collective farmers will have to dig deeper, and so - a normal engine. There is no need to expose clearances on "hydrikas"; they are automatically adjusted if the hydraulic lifters are working.
