Kobelco SK260LC-12M excavator part numbers, taken from the machine's own parts catalogue. Items shared with neighbouring machine generations are confirmed from your model plate before quoting.
Structurally, these 121 numbers fall into 22 Kobelco number series — YN30V, LQ30V, ZD12P among the largest. In practice that means repeated items such as ring, spring, valve and 20 hardware positions.
If you are quoting from this group, start with: ZS23C08025 (capscrew, ×40 per assembly); 2436U1443S332 (spring, ×26 per assembly); ZD12G03000 (o ring -, ×21 per assembly). The full list follows below.
The Valve Mounting (Boom Emergency Lowering Valve, SK310) group on the Kobelco SK260LC-12M contains 121 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 SK260LC-12M 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.
The machine serial number, the part number if you have it, and the symptom. With those three, fitment is confirmed and the quotation follows the same working day. The practical first number to ask for in this group is ZS23C08025.
Yes. Seal items are listed as individual part numbers in the table, so a seal package for one joint can be quoted without buying the whole assembly.
Either. The complete Valve Mounting (Boom Emergency Lowering Valve, SK310) can be quoted as a set, or any single part number from the table — both are normal requests from our trade customers.
