Read as a dataset, the 58 part numbers spread across 20 number series (LC42H, YN42H, ZS18C being the biggest) Expect repeated items such as tube, hyd, lines and 11 hardware positions when you work through it.

The high-quantity positions are: ZM73C12035 (sems-bolt, ×16 per assembly); PV02B01073D3 (cap, ×16 per assembly); ZS28C10035 (capscrew, ×16 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 SK330-8 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.
