Read as a dataset, the 120 part numbers spread across 20 number series (YN30V, LQ30V, ZD12P being the biggest) Expect repeated items such as ring, spring, valve and 20 hardware positions when you work through it.

The high-quantity positions are: ZS23C08025 (capscrew, ×40 per assembly); 2436U1443S332 (seat, spring, ×26 per assembly); ZD12G03000 (o ring -, ×21 per assembly). The full list follows below.

Hydraulic components are the heart of the Kobelco SK240-12: 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 SK240-12, 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.
