Not every engine component belongs to a major assembly, and this group gathers the parts that sit outside them — the castings, covers and hardware that turn a set of assemblies into a running engine. This group covers cylinder blocks and bare castings, sumps and oil pans, timing covers, breathers, dipsticks and tubes, plugs and adaptors, and miscellaneous overhaul hardware. Identification is complicated by the brand's history: engines were developed under Daewoo, sold as Doosan, and the construction equipment division has been rebranded as Develon since 2022. Machines carry different badging across those periods while the engine specification often stays the same, so the engine serial number rather than the machine badge is the reliable reference.
AMS Parts supplies a wide range of general engine parts components for Doosan engines used in power generation, marine, and industrial applications. Browse the full range below, or contact us for specific requirements.
Doosan Infracore's construction equipment division was rebranded Develon from 2022. Engines on pre-transition machines retain Doosan specification, so the engine serial number should be used to confirm the correct part.
Doosan acquired Daewoo's heavy equipment business, and the engine range carries Daewoo design heritage. Part numbers in the 65.xxxxx format date from that period.
The engine serial number and machine model together identify the build. Photographs and measurements help where markings have worn away.
