No illustration for this section
The 5.65M Boom Hydraulic Piping (Swing, 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.
The 5.65M Boom Hydraulic Piping (Swing, Quick Coupler) group on the Kobelco SK240-12 contains 58 separately orderable part numbers. The Ref. column mirrors the callout numbers on the illustration, so a part can be ordered straight from the drawing. Every entry is a genuine Kobelco part number, confirmed against the serial range before we quote.

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.
Structurally, these 58 numbers fall into 15 Kobelco number series — YN42H, ZM73C, ZS18C among the largest. Expect repeated items such as clamp, tube, bracket and 9 hardware positions when you work through it.
The high-quantity positions are: ZS18C12055 (capscrew, ×14 per assembly); ZS18C10050 (capscrew, ×8 per assembly); ZW16H10000 (washer, ×8 per assembly). The full list follows below.
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.
Working from the exploded view is the fastest way to order. Find the component on the drawing, note its callout number, and take the matching reference from the table — that mapping removes the guesswork that comes with describing a part over the phone or in an email.
Usually yes — the callout numbers on the drawing map directly to the Ref. column in the table. If your machine differs by serial range, send a photo of the part and we will confirm before quoting. If that matches your case, quote ZS18C12055 and we will take it from there.
Yes — send the serial and the part number together; where a position changed across the run we flag it and quote the number that matches your build.
Yes. Send the Kobelco SK240-12 serial number with the part number and we confirm the fit from the serial range. Where a component changed during the production run, we flag it before you commit.
