Doosan's mid-to-large excavators use the well-established Kawasaki K-series family, which means genuine parts availability draws from the same broad supply chain as Komatsu, JCB, and Hitachi excavators. Smaller DX models sometimes deviate to a Tong Myung T5 pump instead — always confirm from the nameplate rather than assuming based on size class alone.
