Part numbers as fitted to the Kobelco SK330-8 excavator. Where a position changed during the production run, the serial number settles which one applies to your machine.
Structurally, these 28 numbers fall into 14 Kobelco number series — YN10V, ZS23C, 2441U among the largest. Expect repeated items such as ring, capscrew, plug and 9 hardware positions when you work through it.
The high-quantity positions are: 2441U722S490 (plug, ×18 per assembly); ZS28C06020 (capscrew, ×8 per assembly); YX10V00003S015 (o-ring, ×8 per assembly). The full list follows below.
The parts in this group rarely fail on their own, but they are replaced alongside the components that do — which is why they are listed separately here, ready to be added to any repair order.
Where this section carries no illustration, the parts table below is the authoritative list. Every entry is a real Kobelco part number — nothing on this page is generic or approximated.
Yes — set and bulk orders are normal for us, quoted as one consolidated shipment. If that matches your case, quote 2441U722S490 and we will take it from there.
From single seals to complete group sets — the consolidation logic is the same: one shipment, one freight line, every condition declared.
Yes — orders consolidate into one shipment, and freight is quoted once for the consolidated parcel.
