Based on its design concept, the Daihatsu 6LDK-32 operates as a medium-speed marine auxiliary diesel engine, leveraging a 4-stroke cycle for efficient power generation. With a bore of 320mm and a stroke of 400mm, this engine reaches a rated power output of 2700 kW at 720 RPM, making it suitable for various maritime applications. The fuel system is versatile, capable of using MDO or HFO, with the ability to switch between fuels as needed. Critical areas for maintenance include the fuel injection pump tappet adjustment screw, engine-driven cooling water pump, and valve assembly, particularly for intake and exhaust valves. Care must be taken to use genuine parts to avoid performance degradation and voiding certification.

Free of charge — we forward your request to qualified suppliers for Daihatsu equipment from our network of over 114,000 maritime companies.

Makers and authorised dealers rarely quote marine equipment without the vessel. With these details we usually come back with prices; without them we have to ask first, which costs a few days. If you cannot share the vessel, a photo of the equipment’s rating plate does the same job — send it as a reply to our confirmation e-mail.
