Heavy-duty excavators used in earthmoving, demolition and quarry work need hydraulic parts that hold up under high pressure and repeated duty cycles. Over time, wear on reduction gears, drive shafts and hydraulic sealing faces can cause loss of power, vibration, oil leakage and unplanned downtime. The 404-00100 Doosan Excavator Travel Motor Assembly is engineered for Doosan DH300-7, DH300, DX300 machines, restoring factory-level hydraulic response and consistent output on the job site.
