Kobelco SK250-8 excavator part numbers, taken from the machine's own parts catalogue. Items shared with the closely related SK260LC-8 and the later SK250-10 generation are confirmed from your model plate before quoting.
The 28 entries group into 4 distinct number series, led by YN03M, ZM73C. Expect repeated items such as bolt, ring, retaining and 10 hardware positions when you work through it.
If you are quoting from this group, start with: ZM73C08020 (sems-bolt, ×6 per assembly); YN03M01914P1 (ring,retaining, ×3 per assembly); YN03M01916P1 (ring,retaining, ×2 per assembly). The full list follows below.
Because control components sit inside the cab and under the floor plates, order consolidation matters: a complete set of pins, seals and rods arrives as one kit and the machine is opened once.
Every item is quoted with the condition declared: genuine through original supply channels, or a quality OEM alternative. The declaration is on the quotation, not buried in the invoice.
Yes. Send a photo of the worn part with the serial number and we will match it against this group and quote it. The practical first number to ask for in this group is ZM73C08020.
Cables and rods are catalogue items with fixed part numbers rather than cut-to-length — the serial number confirms the correct length variant.
They are cheap to consolidate. Add them to any existing order and they travel in the same parcel at effectively no extra freight.
