Doosan Excavator Hydraulic Parts: DH and DX Series

Doosan excavator hydraulic parts for DH and DX series machines, from 5-ton mini units to the 50-ton class. We stock main pumps, travel motors, swing motors, control valves, cylinders and seal kits, in five grades: RITO, genuine, rebuild, OEM, aftermarket.

Doosan changed its part numbering between the DH and DX generations, and the two do not cross cleanly. A DH225-7 swing motor and a DX225LC swing motor look alike and carry different numbers, because the swing device was redesigned. Ordering from a DH number for a DX machine is a common and expensive error.
