Read as a dataset, the 13 part numbers spread across 1 number series (YN30V being the biggest) The list is weighted toward repeated items such as repair, kit, valve.

Three numbers worth noting first: YN30V00105S010 (spool, ×4 per assembly); YN30V00105S005 (cover, ×2 per assembly); YN30V00105R100 (repair kit, ×1 per assembly). The full list follows below.

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.

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.
