Kobelco SK260LC-12M · 6.02M Boom Hydraulic Piping · 29 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 6.02M Boom Hydraulic Piping group on the Kobelco SK260LC-12M contains 29 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 SK260LC-12M excavator. Where a position changed during the production run, the serial number settles which one applies to your machine.
Structurally, these 29 numbers fall into 12 Kobelco number series — YN42H, LB42H, LQ42H among the largest. Expect repeated items such as clamp, tube, ring and 1 hardware positions when you work through it.
The high-quantity positions are: YN64H01392D1 (cap, ×26 per assembly); ZM73C12035 (sems bolt -, ×22 per assembly); YN42H02348P1 (clamp, ×6 per assembly). The full list follows below.
The 6.02M Boom Hydraulic Piping group on the Kobelco SK260LC-12M contains 29 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 SK260LC-12M 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 YN64H01392D1 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 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.
