Main engine spare parts
Two-stroke propulsion engines (MAN B&W, Wärtsilä/WinGD, Mitsubishi UE) and their licensee builds — parts follow the engine type designation on the nameplate.
Main engine: what ships order most.
The parts below are what service engineers and superintendents ask for most on this equipment. Every request is matched against the model in the library first, so the supplier gets the exact type, serial and drawing position — not a description.
- cylinder liners, covers and exhaust valves
- piston crowns, rings and skirts
- fuel pumps, injection valves and nozzles
- crosshead and main bearings
- turbocharger and scavenge-air parts
Out of production or too slow from the maker? We have wear parts such as bushings, rollers, pins and shaft sleeves made to drawing or sample in Germany. OceanSphere Fabrication
How a part request works.
Name the make and the model and what the job is: a spare, a service call, a second opinion on a data sheet. We answer by e-mail.

Manufacturers.
Main engine: the manufacturers with the most models in the library. Names with a manufacturer page open it; the others open a search across the full library.
Models.
Main engine: the most complete models in the library. Every row links to specifications, documents and service notes — and to the part request for that exact model.

Questions that come up with this equipment.
Do you supply OEM or equivalent Main engine spare parts?
Both, and we say which is which. You tell us whether the class society or the charterer requires OEM; the desk quotes OEM, OEM-equivalent or reconditioned parts accordingly, each with origin and warranty stated.
How fast can Main engine parts be at the vessel?
Stock parts typically ship within 24–72 hours from the supplier; the quote names the lead time and the delivery port or agent. For urgent cases tell us the ETA and the next port — the desk sources from the nearest stock.
What if the model is not in the library?
Send the nameplate. We identify the unit by hand, add it to the library, and the part request is already on our desk — nothing is lost.
