The 14 entries group into 8 distinct number series, led by YN55V, ZS23C. Expect repeated items such as plate, seal, ring and 3 hardware positions when you work through it.

Send us the Kobelco SK330-8 serial number together with the part number or the symptom you are chasing. We confirm fitment from the serial range before quoting, and mixed orders are consolidated into a single shipment — a set of seals does not travel in its own parcel.

Hydraulic components are the heart of the Kobelco SK330-8: main pump delivery, swing and travel drive, control valve sections and the lines and seals that connect them. When a circuit loses power, drifts under load, or runs noisy when warm, the fault is usually traced to one of the components in this group rather than to the machine as a whole.
