Kobelco SK260LC-12M · Swivel Joint Mounting · 19 part numbers

Illustration reproduced from the Kobelco SK260LC-12M parts catalogue for part identification only. Callout numbers on the drawing match the Ref. column in the table below. Kobelco is a trademark of its respective owner; Shenyue Machinery is an independent supplier of excavator parts.
The Kobelco SK260LC-12M Swivel Joint Mounting breaks down into 19 individually orderable part numbers. The Ref. column mirrors the callout numbers on the illustration, so a part can be ordered straight from the drawing. The list comes straight from the Kobelco SK260LC-12M catalogue for this machine family.

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 19 entries group into 9 distinct number series, led by YN55V, ZS23C. In practice that means repeated items such as joint, swivel, body and 4 hardware positions.
Where to start in this table: YN55V01057P1 (seal, ×5 per assembly); ZM73C12030 (sems bolt -, ×3 per assembly); ZS23C08030 (capscrew, ×3 per assembly). The full list follows below.
Seal kits for this group are quoted from the same table — the O-ring and seal positions carry their own numbers, so a hydraulic repair never forces a purchase at assembly level.
Every hydraulic item we quote is declared by condition: genuine, ordered through original supply channels, or a quality OEM alternative. The declaration appears on the quotation itself, never buried in an invoice, so you know exactly what you are fitting before you commit.
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, YN55V01057P1 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.
