Kobelco SK260LC-12M · Cylinder Hydraulic Piping (Arm Cylinder) · 22 part numbers
No illustration for this section
The Cylinder Hydraulic Piping (Arm Cylinder) is listed without an exploded view in the SK260LC-12M catalogue — the parts table below is the authoritative reference, and every part number is confirmed against your machine serial before we quote.
22 separately orderable part numbers make up the Cylinder Hydraulic Piping (Arm Cylinder) on the Kobelco SK260LC-12M. Where the drawing shows a callout, the Ref. column in the table carries the same number. Every entry is a genuine Kobelco part number, confirmed against the serial range before we quote.

Factory part numbers as fitted to the Kobelco SK260LC-12M excavator. "Ref." matches the callout number on the exploded view where one is shown.
Read as a dataset, the 22 part numbers spread across 15 number series (LB42H, ZD12P, ZS28C being the biggest) The list is weighted toward repeated items such as capscrew, hyd, lines and 7 hardware positions.
Where to start in this table: ZS28C14050 (capscrew, ×8 per assembly); ZW26K14000 (lock washer, ×8 per assembly); ZS28C12040 (capscrew, ×4 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 SK260LC-12M 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.
Yes. Send the Kobelco SK260LC-12M 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. In this group, ZS28C14050 is the number most often quoted for that enquiry.
The machine serial number, the part number if you have it, and the symptom. With those three, fitment is confirmed and the quotation follows the same working day.
Yes. Seal items are listed as individual part numbers in the table, so a seal package for one joint can be quoted without buying the whole assembly.
