Description
Arm / Stick Hydraulic Cylinder to Suit Doosan DX480, DX500, DX520 Excavator
Replace a tired or leaking arm cylinder on your Doosan DX480, DX500, DX520 in one go with this complete arm (dipper) cylinder assembly. Supplied as a ready-to-fit unit — barrel, rod, piston, gland and seals — it's built to OEM specifications for a direct bolt-on replacement with no rebuilding required. Cross-references OEM part number 400305-00428C.
Typical signs it is time for a new arm cylinder: the stick creeps out under load, crowd force drops off when digging, and oil keeps appearing around the rod gland. Fitting a new assembly is usually faster and more cost-effective than stripping, honing and re-sealing the old one. Heavy 45–50 tonne excavators are built for quarry, mining and mass excavation duty, where cylinders face extreme pressures and constant cycling.
