Kobelco SK260LC-12M · Cylinder Mounting (Arm Cylinder) · 44 part numbers
No illustration for this section
The Cylinder Mounting (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.
The Cylinder Mounting (Arm Cylinder) group on the Kobelco SK260LC-12M contains 44 separately orderable part numbers. Callout numbers on the exploded view map one-to-one to the Ref. column in the table. 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.
Structurally, these 44 numbers fall into 10 Kobelco number series — LB01V, YN01V, LB02B among the largest. In practice that means repeated items such as ring, seal, kit and 6 hardware positions.
Where to start in this table: LB01V00019S026 (capscrew, ×14 per assembly); LB01V00018S025 (seal, ×4 per assembly); ZN18C20016 (nut, ×2 per assembly). The full list follows below.
Swing, travel and implement circuits share the same pump flow on the Kobelco SK260LC-12M, 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.
In most cases yes. The wear points on Kobelco SK260LC-12M hydraulic assemblies are individually replaceable and all carry their own part numbers in the table above, so a targeted repair can be quoted without exchanging the complete unit. In this group, LB01V00019S026 is the number most often quoted for that enquiry.
Stocked items leave within one to two working days. Anything that needs ordering through supply channels is quoted with a lead time upfront, and mixed orders are consolidated for dispatch to 30+ countries.
It is the quantity fitted per assembly in the catalogue — useful when a job calls for more than one of the same part, such as O-rings fitted in a pack.
