Structurally, these 11 numbers fall into 6 Kobelco number series — YN30V, ZS23C, ZD12G among the largest. The list is weighted toward repeated items such as capscrew, valve, ring and 4 hardware positions.

Three numbers worth noting first: ZS23C12105 (capscrew, ×3 per assembly); ZS23C10025 (capscrew, ×2 per assembly); YX35V00002S171 (capscrew, ×2 per assembly). The full list follows below.

Rebuild-at-component-level is the practical route for most Kobelco SK250-8 hydraulic assemblies. Wear shows up at predictable points — spool clearances, valve plates, bearing sets, seal packages — and those items are listed individually, so you can quote only what is worn instead of exchanging the complete unit.

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.
