Kobelco SK240-12 · Cylinder Mounting (Bucket Cylinder) · 35 part numbers
No illustration for this section
The Cylinder Mounting (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.
The Cylinder Mounting (Bucket Cylinder) group on the Kobelco SK240-12 contains 35 separately 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.

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 35 numbers fall into 9 Kobelco number series — YN01V, 2438U, YN12B among the largest. Expect repeated items such as ring, repair, kit and 4 hardware positions when you work through it.
The high-quantity positions are: ZS23C16075 (capscrew, ×12 per assembly); YN01V00153S022 (ring, ×4 per assembly); ZN18C16013 (nut, ×2 per assembly). The full list follows below.
The Cylinder Mounting (Bucket Cylinder) group on the Kobelco SK240-12 contains 35 separately orderable part numbers, all listed in the table below with the quantity fitted per assembly. Every number in the table is a real Kobelco part number taken from the machine's own parts catalogue, not a generic cross-reference.
Send us the Kobelco SK240-12 serial number together with the part number or the symptom you are chasing. We confirm fitment from the serial range before quoting, and mixed orders are consolidated into a single shipment — a set of seals does not travel in its own parcel.
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 ZS23C16075 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.
