Kobelco SK240-12 · Cylinder Hydraulic Piping (Bucket Cylinder) · 14 part numbers
No illustration for this section
The Cylinder Hydraulic Piping (Bucket Cylinder) 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.
This page lists all 14 part numbers in the Kobelco SK240-12 Cylinder Hydraulic Piping (Bucket Cylinder). The Ref. column mirrors the callout numbers on the illustration, so a part can be ordered straight from the drawing. All numbers are taken from the machine's own parts catalogue — nothing here is generic.

Kobelco SK240-12 excavator part numbers, taken from the machine's own parts catalogue. Items shared with neighbouring machine generations are confirmed from your model plate before quoting.
Read as a dataset, the 14 part numbers spread across 10 number series (YN43H, ZS18C, YX42H being the biggest) Expect repeated items such as capscrew, band, nipple and 5 hardware positions when you work through it.
If you are quoting from this group, start with: ZS28C10030 (capscrew, ×4 per assembly); ZS18C10030 (capscrew, ×2 per assembly); ZW26X10000 (lock washer, ×2 per assembly). The full list follows below.
For workshops planning a full hydraulic health check, the practical sequence is seals first, then wear items such as valve plates and bushings, and only then complete assemblies. The table below supports that sequence because every level of the breakdown is separately orderable.
Rebuild-at-component-level is the practical route for most Kobelco SK240-12 hydraulic assemblies. Wear shows up at predictable points — spool clearances, valve plates, bearing sets, seal packages — and those items are listed individually, so you can quote only what is worn instead of exchanging the complete unit.
Slow or drifting functions, a circuit that weakens as the oil warms, noise under load, and external leakage at joints are the usual reports. Pressure testing points to the circuit; the drawing callouts then point to the part. The practical first number to ask for in this group is ZS28C10030.
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.
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.
