Factory part numbers as fitted to the Kobelco SK330-8 excavator. "Ref." matches the callout number on the exploded view where one is shown.
The 25 entries group into 13 distinct number series, led by LC32H, YN32H. Expect repeated items such as hose, ring, connector and 5 hardware positions when you work through it.
Where to start in this table: HM83C12035G1 (sems-bolt, ×10 per assembly); ZM73C12030 (sems-bolt, ×4 per assembly); ZD12P04800 (o-ring, ×3 per assembly). The full list follows below.
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.
We quote new components from this table — genuine or OEM by declaration — rather than exchange units, so you know exactly what is being fitted. In this group, HM83C12035G1 is the number most often quoted for that enquiry.
Slow or drifting functions, a circuit that weakens as the oil warms, noise under load, and external leakage at joints are the usual reports. Pressure testing points to the circuit; the drawing callouts then point to the part.
Usually yes — the callout numbers on the drawing map directly to the Ref. column in the table. If your machine differs by serial range, send a photo of the part and we will confirm before quoting.
