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

Frequently asked

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.
