Marine engine spare parts from China
Spares for auxiliary and generator-set engines common on Chinese-built tonnage — MAN L23/30H, MAN 16/24 and 21/31, DAIHATSU DK20/DK28/DE18/DC17, Cummins and Henan TBD — with stock for the fast-moving items.
Which engines this page covers
Our engine-maker list is built around the auxiliary engines that dominate Chinese newbuildings: MAN L23/30H, MAN 16/24 and MAN 21/31, DAIHATSU DK20 / DK28 / DE18 / DC17, Cummins and Henan TBD generator sets. Fast-moving items — cylinder head components, fuel injection parts, pistons and liners, bearings, seals, turbocharger cartridges, coolers and filters — are held in stock; larger assemblies are made to order.
Genuine, OEM-licensed or equivalent — stated every time
Engine spares are where the difference between an OEM part, a licensed part and an “equivalent” matters most: it changes the price, the lead time and the class position. Every quotation names the maker of the part we are offering and what documentation it carries, so the technical department can decide rather than discover.
Getting the right part number the first time
Send the engine maker, type and serial number, the position description and the part number from the spare parts catalogue. If the catalogue is not at hand, a photo of the nameplate plus the component in place usually resolves it; for injection equipment the element and nozzle numbers matter more than the engine model.

Frequently asked questions
Are the parts genuine OEM?
We quote genuine OEM, OEM-licensed and equivalent options where they exist, and name which is which. Nothing is described as OEM unless it is.
How fast can a cylinder head or liner be delivered?
Fast-moving items are held in stock and can leave Shanghai within days. Larger assemblies are quoted with a realistic production date, typically a few weeks depending on the maker.
Can you supply for engines not listed here?
Often yes — the list reflects what we are asked for most, not a limit. Send the maker, type and serial number and we will confirm.
