Part numbers as fitted to the Kobelco SK250-8 excavator. Where a position changed during the production run, the serial number settles which one applies to your machine.
Structurally, these 29 numbers fall into 15 Kobelco number series — YN10V, ZS23C, 2441U among the largest. In practice that means repeated items such as ring, capscrew, plug and 9 hardware positions.
The high-quantity positions are: 2441U722S490 (plug, ×17 per assembly); ZS28C06020 (capscrew, ×8 per assembly); YX10V00003S015 (o-ring, ×8 per assembly). The full list follows below.
Every line item is quoted with its condition declared: genuine, ordered through original supply channels, or a quality OEM alternative. The declaration appears on the quotation itself.
If the item you need sits between two groups, send us the part number — our catalogue coverage for the Kobelco SK250-8 runs across every group, and this page is only one of them.
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.
