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.
Read as a dataset, the 22 part numbers spread across 11 number series (YN42H, ZS28C, LB43H being the biggest) The list is weighted toward repeated items such as capscrew, clamp, washer and 8 hardware positions.
If you are quoting from this group, start with: ZW26K12000 (lock washer, ×12 per assembly); ZS18C16040 (capscrew, ×8 per assembly); ZS28C12040 (capscrew, ×8 per assembly). The full list follows below.
Every hydraulic item we quote is declared by condition: genuine, ordered through original supply channels, or a quality OEM alternative. The declaration appears on the quotation itself, never buried in an invoice, so you know exactly what you are fitting before you commit.
The 3.1M Arm Hydraulic Piping (Hydraulic Breaker) group on the Kobelco SK260LC-12M contains 22 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.
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. The practical first number to ask for in this group is ZW26K12000.
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.
Yes — send the serial and the part number together; where a position changed across the run we flag it and quote the number that matches your build.
