Aftermarket Replacement Parts for Develon Equipment

Develon is the name Doosan's construction equipment business has used since 2023, so most machines in the field still carry the Doosan badge, and older ones the Daewoo name. The model names carry over unchanged: DX crawler excavators such as the DX140LC, DX225LC and DX300LC, DX wheeled excavators such as the DX140W and DX190W, DL wheel loaders such as the DL300, DL420 and DL450, and DA articulated dump trucks such as the DA30 and DA40. The number after the dash (-3, -5, -7) marks the generation, and parts often change between generations of the same model.

Common replacements include the fuel and water separator filters that replace Develon 400508-00178 and 400508-00118, the hydraulic filter that replaces Develon K1022788 and the DEF filter that replaces Develon 400406-01303. Seals, O-rings, hoses and hardware make up much of the rest of the range. Check the model and serial number on the machine plate against each product page, and contact our team with your machine details if you need help confirming a part.

Aftermarket vs OEM Develon Parts

Aftermarket parts are built to fit and perform like the original Develon or Doosan part they replace, and each product page lists the OEM part number it replaces. For routine service parts such as filters, seals and hardware, an aftermarket replacement is usually the most cost effective way to keep an older Doosan or newer Develon machine working.
