MAN Engines marine diesels behind engine-room enquiries
MAN Engines is the engine division of MAN Truck & Bus, and its high-speed marine diesels work on passenger ferries, pilot boats, lifeboats, fishing vessels, tugs and cargo vessels. Each engine is offered in light, medium and heavy duty versions, and the version is written as LE followed by a number after the engine type. Two engines of the same type with different LE numbers are set up for different duty, so the full code is what the parts are matched to.
D2676 LE4xx
The current in-line six-cylinder engine with common-rail injection, in light, medium and heavy duty versions. It took over from the D2866 and D2876. Filters, injectors, cooler elements and gasket sets are quoted against the full LE version and the serial.
D2862 LE44x · LE446 · LE456
The twelve-cylinder V engine, offered in light, medium and heavy versions and as a heavy-duty engine for tugs and cargo vessels. Versions such as LE446 and LE456 are separate builds of the same type, so the version number goes into every line.
D2868 LE4xx
The eight-cylinder V engine of the same generation, in marine versions for lighter duty among others. Parts are quoted against the complete code and serial, with the duty class noted in the enquiry.
D2866 · D2876 LE4xx
The in-line sixes the D2676 replaced, still in service on fishing vessels and workboats; the D2876 ran in LE401, LE402, LE404 and LE405 versions among others. The version is copied from the plate, and items revised since the build are named in the reply.
D2842 LE4xx
The earlier V12 marine engine, met in versions such as LE409 and LE410. Photographs of the plate, the engine and the removed part support the enquiry when the plate is hard to read.
MAN Engines components that reach an RFQ
The list follows a high-speed marine diesel from the fuel side to the cooling side and the add-on units. Each line can carry the part number from the parts catalogue or from an earlier order next to the description.
- Fuel filter elements, pre-filters and water separators
- Lube oil filters, crankcase breather elements and air filter elements
- Injectors, common-rail items, high-pressure pump parts and high-pressure pipes
- Cylinder head gaskets, valve cover gaskets and overhaul gasket sets
- Sea water pump impellers and pump repair kits
- Heat exchanger, keel cooler and charge-air cooler elements, anodes and gaskets
- Coolant pump parts, thermostats, hoses and drive belts
- Turbocharger gasket sets and turbocharger units, quoted from the turbocharger plate
- Starter motors, charging alternators, sensors and engine control items
- Exhaust manifold gaskets and bellows
What to read off a MAN Engines diesel before ordering
Two things come off the engine plate first: the full engine code with its LE version and the engine serial number. A clear photograph of the plate settles most of the points below; the rest come from the ship's own records.
- Full engine code exactly as printed, for example D2862 LE446 or D2676 LE435
- Engine serial number from the same plate
- Duty on board: propulsion engine or generator engine, and the duty class if known
- Cooling: heat exchanger or keel cooling
- Part numbers from the parts catalogue, an earlier invoice or the old part itself
- Gearbox make and type for a propulsion engine, ordered separately
Supply route review for MAN Engines marine diesels
Engines of one type are built in several LE versions for different duty, and the older types were replaced rather than renamed. The full code and serial are settled first, and the supply route is then chosen line by line.
LE version before the type
A D2862 LE446 and a D2862 LE456 share a type but are separate builds. Part numbers are checked against the complete code with its version and against the serial, not against the type alone.
Not the two-stroke MAN
The name MAN on a plate can mean either MAN Engines or the separate two-stroke and medium-speed business. A D-code with an LE version belongs here; a code such as S50MC or L21/31 belongs on the other MAN pages.
Original reference or accepted equivalent
Parts a surveyor will inspect are quoted on the original reference. Filters, impellers, anodes and belts that carry their own makers' markings can also go on an equivalent-source path for the ship's own spares, within the buyer's list of accepted sources.
Replaced engines, kept in service
A D2866 or D2876 that was replaced in the programme by the D2676 keeps its own parts list. The reply names any item superseded since the engine was built, and the ship decides whether to take the newer reference.
MAN Engines marine diesel parts — questions from the engine room
Our engine says MAN. Does it belong on this page or on the MAN B&W page?
If the code starts with D and carries LE and a version number, such as D2862 LE446, it is a MAN Engines high-speed diesel and belongs here. Two-stroke codes such as S50MC and medium-speed codes such as L21/31 come from the separate MAN business with its own pages.
Which data from the plate is needed for a MAN Engines parts enquiry?
The complete engine code with its LE version, such as D2676 LE435, and the serial number. Add whether the engine drives the propeller or a generator, how it is cooled, and any part numbers from the parts catalogue or earlier orders.
Can Vessel Core quote parts for an older D2842 or D2876?
Often, yes. Photographs of the plate, the whole engine and the removed part, plus an earlier invoice for the same engine if the ship has one, are usually enough to start. Each line is confirmed before it is quoted.
Does Vessel Core repair MAN Engines diesels?
No. Vessel Core identifies and supplies parts. Repairs and overhauls are arranged by the owner with a workshop of their choice, and the enquiry follows the job list that workshop draws up.
Is Vessel Core connected to MAN Engines?
No, and there is no agreement of any kind. Vessel Core holds no distribution, representation or partnership agreement with MAN Engines, and quoting a component against one of its designations implies no approval by the maker and no claim of interchangeability.
Send the engine plate and the list of items.
Copy the full D-code with its LE version and the serial from the plate, say what the engine drives and how it is cooled, then list the items and the port. Gearbox and generator lines are kept apart from the engine lines.
