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.

Hydraulic components are the heart of the Kobelco SK330-8: main pump delivery, swing and travel drive, control valve sections and the lines and seals that connect them. When a circuit loses power, drifts under load, or runs noisy when warm, the fault is usually traced to one of the components in this group rather than to the machine as a whole.

Swing, travel and implement circuits share the same pump flow on the Kobelco SK330-8, which is why a fault in one function can point back to a component listed in this group. A pressure test narrows the circuit down; the drawing then narrows it to a part number.
