Kobelco SK260LC-12M · Cylinder Mounting (Bucket Cylinder) · 37 part numbers
No illustration for this section
The Cylinder Mounting (Bucket 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.
The Kobelco SK260LC-12M Cylinder Mounting (Bucket Cylinder) breaks down into 37 individually orderable part numbers. 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.

Factory part numbers as fitted to the Kobelco SK260LC-12M excavator. "Ref." matches the callout number on the exploded view where one is shown.
The 37 entries group into 7 distinct number series, led by LB01V, YN12B. The list is weighted toward repeated items such as ring, seal, kit and 5 hardware positions.
Where to start in this table: YN01V00148S027 (capscrew, ×14 per assembly); LB01V00020S025 (seal, ×4 per assembly); ZN18C16013 (nut, ×2 per assembly). The full list follows below.
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.
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.
We quote new components from this table — genuine or OEM by declaration — rather than exchange units, so you know exactly what is being fitted. In this group, YN01V00148S027 is the number most often quoted for that enquiry.
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.
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.
