Read as a dataset, the 48 part numbers spread across 24 number series (YN32H, ZD12P, YM32H being the biggest) The list is weighted toward repeated items such as hose, ring, elbow and 6 hardware positions.

If you are quoting from this group, start with: HM83C12035G1 (sems bolt -, ×4 per assembly); HM83C12040G1 (sems bolt -, ×4 per assembly); ZH22X04000 (connector, ×2 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.
