Regular maintenance is crucial for ensuring the reliable operation of marine auxiliary diesel engines, particularly for the Daihatsu 6LDK-36e-GS-60Hz model. This engine features a bore of 360mm and a stroke of 480mm, producing 3540 kW of power at 900 RPM. It is designed to run on heavy fuel oil (HFO) or marine diesel oil (MDO) and operates at a frequency of 60 Hz. The engine's specifications are derived from a verified workflow process, ensuring its power output and other critical parameters are accurate. Common issues reported for this engine series include the loosening of fuel injection pump tappet adjustment screws, which requires regular preventive maintenance. Additionally, the engine-driven cooling water pump needs periodic maintenance and parts replacement. Valve assembly tolerances are critical, especially for the intake and exhaust valves, where caution is advised during assembly. Exhaust valve guide and spindle wear limits should also be monitored, although specific limits are not publicly available. Daihatsu warns against using imitation parts, as they can degrade performance and void any certifications.

Makers and authorised dealers rarely quote marine equipment without the vessel. With these details we can check availability and prices faster; without them we may have to ask first, which can cost a few days. If you cannot share the vessel, a photo of the equipment’s rating plate does the same job — attach it below or send it as a reply to our confirmation e-mail.
