Engine MAN D2866, description and characteristics

The MAN D2866 diesel engine series is available in two versions: D2866 2V and D2866 4V. The 4-stroke engine design of this series has 6 motors. The cylinders use a direct injection system, which has many advantages. MAN engines are equipped with a D2866 exhaust turbocharger with an intermediate quality system. To cool the coolant in engines of this model, ordinary water is used.

MAN D2866 2V – these are motors intended for use in industrial installations and for electricity generators. According to the type of load, the generators should be classified as LTP units (Limited Power Time), that is, operate in the so-called backup mode, which allows them to be used for up to 500 hours per year at variable power and 300 hours in breaks (with consecutive maintenance) without overloads .

D2866 MAN 4V is a motor version designed for use in generator sets of the PRP (Prime Power) classification type. This type involves the constant use of a generator to generate energy for an unlimited number of hours per year. Such generators are able to withstand overload, unlike the LTP type. True, only by 10% of the permissible power and more than once every 12 hours for a duration of no longer than one hour.

The volume of the MAN D2866 4V is 11.9 liters. engines Weight is 1180 kg, and the power they produce, depending on the modification, is 280 or 322 kW. The maximum torque of engines in this series is 1782 Nm or 1708 Nm depending on the configuration.

The working volume of the D2866 MAN 2V engines is also 11.9 liters. Depending on the rotation modification, the speed can be 1500 rpm (50 Hz) or 1800 rpm (60 Hz). In accordance with this, the generated power reaches 360-400 kW.

D 2866 cylinder - 6-LF34 in-line water-cooled engine, produced in 1998. Engine power is 228 hp. (310 kW) with an engine capacity of 11967 cm3.

MAN TGA 18.480: Broken bearings on the fan drive shaft of the MAN D2876LF12 engine

On a MAN TGA 18.480 truck, the engine cooling radiator fan began to vibrate and hit the diffuser. I consulted with specialists and they recommended that I replace the fan drive hub, which I did. However, the replacement did not help and the vibrations did not go away.

I drove like this for some time until something terrible happened - at about 600 thousand km, the fan drive shaft broke and the gear teeth bit. The hub I recently replaced was simply torn out, and the fan and fan shroud were significantly damaged.

There is nothing to do - I started disassembling the damaged mechanism. I did not remove the radiator during the process, because... he didn't interfere with work.

I unscrewed the 3 bolts holding the fan drive shaft, but I couldn’t remove it straight away. Then, he rested the board against the pulley and began to slowly knock with a hammer, and also asked an assistant to use a mounting tool to rock the shaft back and forth. After some time, the drive was finally dismantled.

I disassembled the unit and realized what the problem was. It turned out that the bearings in the fan drive were broken (there are 2 of them) and this led to the mechanism starting to vibrate.

I bought a new fan drive, as well as the fan itself and the casing. The prices for spare parts were, as always, pleasing.

MAN engines use both an adjustable fan support with a separate mounting ring (Euro 3) and a non-adjustable one. Because in my case, the support was adjustable, then I proceeded to adjust the gap of the side surface of the teeth.

Before installation, using a mounting sleeve (zero axial clearance), I secured the fan shaft in the shaft housing. Next, I started installation and configuration.

I took a measuring tape and used it to apply two markings (7 mm apart) on the upper side of the fan support clamp;
I placed a new oil scraper ring on the fan support and lubricated it with oil, after which, using a rotational movement, I carefully installed it in place;
I tightened the flange thoroughly, but did it in such a way that the fan support continued to rotate by hand;
Without using tools, I turned the fan support counterclockwise by hand and made a mark on the mating part of the housing;
I turned the fan support 7 mm clockwise, after which I carefully tightened the flange, while maintaining the required tightening torque. Next, I manually turned it counterclockwise until it stops and turned it clockwise 7 mm;

When I installed the fan drive, I pulled the belt pulley as a check and made sure that it did not move, because. play can cause the shaft to hit the gears and thus soon break them.

Next, I started the engine and realized that the vibrations had disappeared and the engine radiator cooling fan began to work quietly, i.e. how to.

Thus, if suddenly your fan begins to touch the diffuser, then immediately look at the hub, and if everything is in order with it, then remove the fan drive and check its bearings.

If you miss the moment, you can end up with significant unplanned expenses. Service technicians say that on the MAN TGA 18.480 with the MAN D2876LF12 engine, problems in this unit occur extremely often.

Viking Drakkar “Project VD-50” (length 16.2 m, engine LOMBARDINI Marine LDW2204M - 60 hp and diesel generator LOMBARDINI Marine LMG4000 - 3.5 KW)
The Drakkar, built at our shipyard, is intended for walks and entertainment in the Viking style Party, as well as to participate in installations and reconstructions of relevant historical events. That is why the task was to create not only a practical and easy-to-use vessel, but also to preserve its visual authenticity, seaworthiness and weight characteristics. Based on this, in order not to violate the integrity and historical appearance of the vessel, a compact and low-noise engine was required that would not be conspicuous and would take up little space.

The Gidrokom-Motors company proposed an excellent option - to install a LOMBARDINI Marine LDW2204M diesel engine as the main engine, and, in addition, to equip the vessel with a LOMBARDINI Marine LMG4000 diesel generator, which had all the required characteristics, and due to their small size, were secretly installed under the deck of the longship .

The Drakkar, built at our shipyard, is designed for Viking Party-style excursions and entertainment, as well as for participation in installations and reconstructions of relevant historical events. That is why the task was to create not only a practical and easy-to-use vessel, but also to preserve its visual authenticity, seaworthiness and weight characteristics. Based on this, in order not to violate the integrity and historical appearance of the vessel, a compact and low-noise engine was required that would not be conspicuous and would take up little space.

At our shipyard, a boat was manufactured intended for operation in the waters of the Atlantic and Mediterranean Sea. The customer required a reliable, powerful engine with low fuel consumption and small dimensions so that it could fit in the small engine compartment of the boat.

The Gidrokom-Motors company has proposed an option that fully meets these requirements - a LOMBARDINI Marine engine with a power of 180 hp, equipped with a MerCruiser BRAVO sterndrive, which provides the vessel with a speed of 38 knots on the river surface in long-term mode, and at sea with waves of 2- 3 points - 27 knots, and fuel consumption is approximately 20 l/h at cruising speed.

“Trawler” type motor yacht of project “TY-43” (length 13.4 m, HYUNDAI H6D1T engine - 180 hp and diesel generator LOMBARDINI Marine LMG9000 - 8 KW)

At our shipyard, a motor yacht was built according to the design of designer Bruce Roberts, intended for cruises in various water basins. Naturally, it had to be equipped with an engine that would be distinguished by high technical characteristics, reliability, durability and the ability to operate uninterruptedly in different operating modes.

The Hydrokom Motors company proposed installing a HYUNDAI H6D1T engine on the yacht, which had a clear classic design. This model, intended for commercial use on heavy displacement vessels, has a long service life and makes it possible to operate at full power for a long time, which is what the customer required.

To provide the vessel with electricity, a low-noise and economical diesel generator LOMBARDINI Marine LMG9000 was proposed, and a complete shaft-propeller group was supplied.

Excursion passenger ship "Ruska" (length 12.8 m, HYUNDAI h5DT engine - 94 hp)

We turned to the Gidrokom-Motors company because we needed to install a modern and quiet engine, reliable and with low fuel consumption. Having familiarized ourselves with the characteristics of our vessel, its operating conditions, as well as our requirements for the new model, we were offered a HYUNDAI h5DT marine engine, which not only had the power we needed, but also met our requirements - no vibration and low noise. In addition, for a comprehensive delivery, we were recommended a shaft-screw group, which, like the engine itself, was installed by company representatives.

Pusher tug (raft guide) of the R-33B project, replacement of the propulsion system (HYUNDAI DD6AC engines - 335 hp - 2 pcs.)

It was necessary to replace the outdated engines on the R-33B pusher tug. When we contacted the Gidrokom-Motors company, we were offered to develop a modernization project, which included the replacement of two main engines, namely the outdated 6NVD-26A3 with modern HYUNDAI DD6AC diesel engines.

The result of this replacement, which was carried out by our contractors, was high fuel efficiency and uninterrupted operation even when using SMT. Now the tug is in excellent technical condition and carries out cargo transportation along the Ob and Irtysh rivers. The new engines meet all the declared characteristics, ensuring uninterrupted operation of the tug. Thank you!

Motor ship "Sintez" (project 1430)

It was necessary to modernize the passenger ship "Sintez" in order to improve its technical characteristics. We contacted the Gidrokom-Motors company, where we were offered a modernization project consisting of replacing outdated 3D12A engines with two new HYUNDAI DD6AC diesel engines with DMT180HL reverse gearboxes. The result of such a replacement, thanks to the modern design of the engines and their high technical characteristics, turned out to be excellent - absence of vibrations and low noise, which is primarily necessary for a passenger ship, as well as high fuel efficiency. After replacing the engines, carried out by the company’s specialists, the ship operates smoothly and carries out passenger flights along the Volga and Kama. Thank you!

River limousine Queen Launch 46 (length 14.0 m, engine LOMBARDINI Marine LDW245JMTI/A - 240 hp)

When constructing the Queen Launch river limousine, the task was to create a high level of comfort and provide luxury permeated with a. And this could be achieved not only by luxurious finishing of the body and interior, but, above all, by a properly selected engine, which would be not only powerful, but also compact and low-noise at the same time.

The Gidrokom-Motors company offered us to equip the vessel with a LOMBARDINI Marine LDW245JMTI/A engine, which fully met these requirements. Thanks to the particularly low noise characteristic of this engine, we received an award for interior quietness, which can be compared with premium cars.
