Read as a dataset, the 14 part numbers spread across 3 number series (YN22V, ZD12P, 2436R being the biggest) In practice that means repeated items such as ring, spring, back and 2 hardware positions.

If you are quoting from this group, start with: ZD12P02400 (o-ring, ×1 per assembly); ZD12P02240 (o-ring, ×1 per assembly); YN22V00001S521 (spring, ×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.
