Daihatsu DK-20: the spares that keep a generator online

Fuel injection and cylinder parts for one of the most common Japanese auxiliary engines.

Daihatsu DK-20 engines, in five, six and eight cylinder versions, power the generators on a great many Japanese and Korean built vessels. Spares are widely available, which makes it easy to forget that versions differ.

Items we see most often on DK-20 requisitions

  • Fuel injection valve nozzles and fuel pump plungers
  • Piston rings, piston pin bushes and connecting rod bearings
  • Cylinder liner O-rings and cylinder head gaskets
  • Inlet and exhaust valves, seats and guides
  • Engine gauges and thermometers on the local panel

Older DK-20 engines and later production engines do not always share part numbers, and licence-built engines can differ again. Include the engine number from the nameplate on every requisition.

Send the nameplate photo and the parts list and we will quote genuine and alternative options.
