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.
The 33 entries group into 19 distinct number series, led by LQ33H, YN52V. In practice that means repeated items such as tank, element, hyd and 9 hardware positions.
The high-quantity positions are: ZM73C10025 (sems-bolt, ×12 per assembly); ZS13C20040 (capscrew, ×4 per assembly); ZW13H20000 (washer, ×4 per assembly). The full list follows below.
Seal kits for this group are quoted from the same table — the O-ring and seal positions carry their own numbers, so a hydraulic repair never forces a purchase at assembly level.
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.
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. If that matches your case, quote ZM73C10025 and we will take it from there.
Either. The complete Tank Installation,Hyd can be quoted as a set, or any single part number from the table — both are normal requests from our trade customers.
In most cases yes. The wear points on Kobelco SK250-8 hydraulic assemblies are individually replaceable and all carry their own part numbers in the table above, so a targeted repair can be quoted without exchanging the complete unit.
