No illustration for this section
The Undercarriage Assembly (SK260, SK280) 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.
8 separately orderable part numbers make up the Undercarriage Assembly (SK260, SK280) on the Kobelco SK260LC-12M. Take the callout number from the drawing and match it in the Ref. column below. Every entry is a genuine Kobelco part number, confirmed against the serial range before we quote.

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.
Read as a dataset, the 8 part numbers spread across 6 number series (YN01F, ZM73C, LB01F being the biggest) The list is weighted toward repeated items such as sems, bolt, low and 3 hardware positions.
The high-quantity positions are: ZM73C12030 (sems bolt -, ×12 per assembly); HS13F18050G1 (capscrew, ×8 per assembly); LQ01F01084P1 (cover assy, ×2 per assembly). The full list follows below.
This group covers components that do not fall under the main hydraulic, structural or engine headings — but the ordering logic is identical: find the item on the exploded view where one exists, note the callout number, and take the matching part number from the table.
The parts in this group rarely fail on their own, but they are replaced alongside the components that do — which is why they are listed separately here, ready to be added to any repair order.
Photos speed up identification, but the order is always confirmed against a part number — the photo gets us there faster. If that matches your case, quote ZM73C12030 and we will take it from there.
Both are available and the condition is declared on every line of the quotation — genuine via original supply channels, or a quality OEM alternative.
Yes — orders consolidate across machines and groups into one shipment whenever it makes sense.
