Doosan excavators (the brand is now marketed as Develon) drive the cooling fan hydraulically, so fan speed follows both engine coolant temperature and hydraulic oil temperature instead of engine rpm alone. This section covers replacement hydraulic fan motors and fan pumps for Doosan DX-series machines, including DX380, DX420, DX490, DX500, DX520, DX530, DX700 and DX800 applications.
Each unit is supplied as a bolt-on assembly with the mounting flange, shaft and port orientation matched to the original, and is pressure-checked and photographed before dispatch. If the fan runs slowly at idle, will not reverse to clean the radiator cores, or the machine alarms for high coolant temperature, work through our διάγνωσης υδραυλικού κινητήρα ανεμιστήρα before ordering. For other OEM brands, browse the full hydraulic fan motor range.
