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 30 entries group into 10 distinct number series, led by LQ01V, 2438U. The list is weighted toward repeated items such as ring, repair, kit and 2 hardware positions.
If you are quoting from this group, start with: ZS23C16075 (capscrew, ×12 per assembly); YN12B02221P1 (bushing, ×4 per assembly); YN01V00153S022 (ring,wiper, ×4 per assembly). The full list follows below.
Working from the exploded view is the fastest way to order. Find the component on the drawing, note its callout number, and take the matching reference from the table — that mapping removes the guesswork that comes with describing a part over the phone or in an email.
For workshops planning a full hydraulic health check, the practical sequence is seals first, then wear items such as valve plates and bushings, and only then complete assemblies. The table below supports that sequence because every level of the breakdown is separately orderable.
Stocked items leave within one to two working days. Anything that needs ordering through supply channels is quoted with a lead time upfront, and mixed orders are consolidated for dispatch to 30+ countries. The practical first number to ask for in this group is ZS23C16075.
It is the quantity fitted per assembly in the catalogue — useful when a job calls for more than one of the same part, such as O-rings fitted in a pack.
Both. Every quotation states the condition of each item — genuine through original supply channels, or a quality OEM alternative — so the choice is yours and it is documented.
