Read as a dataset, the 87 part numbers spread across 9 number series (YN30V, LQ30V, 2436U being the biggest) The list is weighted toward repeated items such as spring, spool, repair and 13 hardware positions.

If you are quoting from this group, start with: ZS23C06025 (capscrew, ×40 per assembly); 2436U1443S332 (seat,spring, ×24 per assembly); ZD12P02400 (o-ring, ×19 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.
