Listed for the Kobelco SK330-8 excavator. Every number can be quoted on its own or as a complete set, and fitment is confirmed from your machine serial before we price it.
Structurally, these 31 numbers fall into 7 Kobelco number series — LC01V, 2438U, LQ01V among the largest. In practice that means repeated items such as ring, repair, kit and 3 hardware positions.
Three numbers worth noting first: ZS23C18080 (capscrew, ×12 per assembly); LQ01V00003S017 (ring,back up, ×2 per assembly); LC01V00044S018 (ring,slide, ×2 per assembly). The full list follows below.
The Cylinder Assembly,Boom group on the Kobelco SK330-8 contains 31 separately orderable part numbers, all listed in the table below with the quantity fitted per assembly. Every number in the table is a real Kobelco part number taken from the machine's own parts catalogue, not a generic cross-reference.
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.
Both. Every quotation states the condition of each item — genuine through original supply channels, or a quality OEM alternative — so the choice is yours and it is documented. On the SK330-8, that usually comes back to ZS23C18080 (capscrew) in this group.
We quote new components from this table — genuine or OEM by declaration — rather than exchange units, so you know exactly what is being fitted.
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.
