Read as a dataset, the 76 part numbers spread across 21 number series (YN03H, ZD12P, YN30V being the biggest) In practice that means repeated items such as ring, hose, clamp and 15 hardware positions.

Where to start in this table: HM83C10035G1 (sems bolt -, ×48 per assembly); ZE12X16000 (clamp, half, ×16 per assembly); ZD12P03400 (o ring -, ×10 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 SK240-12 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.
