No illustration for this section
The 2.94M Arm Hydraulic Piping (Quick Coupler) is listed without an exploded view in the SK240-12 catalogue — the parts table below is the authoritative reference, and every part number is confirmed against your machine serial before we quote.
10 separately orderable part numbers make up the 2.94M Arm Hydraulic Piping (Quick Coupler) on the Kobelco SK240-12. Take the callout number from the drawing and match it in the Ref. column below. All numbers are taken from the machine's own parts catalogue — nothing here is generic.

Part numbers as fitted to the Kobelco SK240-12 excavator. Where a position changed during the production run, the serial number settles which one applies to your machine.
Read as a dataset, the 10 part numbers spread across 6 number series (YN43H, ZD12A, ZC26M being the biggest) In practice that means repeated items such as tube, clamp, ring and 2 hardware positions.
The high-quantity positions are: ZM73C10040 (sems bolt -, ×7 per assembly); ZC26M18011 (clamp, ×6 per assembly); YN43H01953D4 (hose, ×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.
It is the quantity fitted per assembly in the catalogue — useful when a job calls for more than one of the same part, such as O-rings fitted in a pack. If that matches your case, quote ZM73C10040 and we will take it from there.
Both. Every quotation states the condition of each item — genuine through original supply channels, or a quality OEM alternative — so the choice is yours and it is documented.
We quote new components from this table — genuine or OEM by declaration — rather than exchange units, so you know exactly what is being fitted.
