Doosan DX140LC Hydraulic Pump

Doosan's mid-to-large DX-series excavators mostly run Kawasaki's well-established K-series pumps (the same broad family used across Komatsu, JCB, and Hitachi machines), but the DX140LC specifically deviates for some production runs, using a Tong Myung T5 pump instead. Neither is "wrong" — both are genuine OEM fitments — but they aren't interchangeable, so checking your existing pump's nameplate directly is the only reliable way to confirm which one your specific machine has before ordering.
