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 19 numbers fall into 9 Kobelco number series — LB12B, B16T, 2445R among the largest. Expect repeated items such as shim, link, pin and 2 hardware positions when you work through it.

The Arm Assembly (SK310) group on the Kobelco SK260LC-12M contains 19 separately orderable part numbers. The table below lists each one with its quantity per assembly, taken directly from the machine's own parts catalogue.
Send the Kobelco SK260LC-12M serial number with your enquiry. Pin and bushing positions changed across the production run on several SK260LC-12M variants, and the serial number is the fastest way to confirm the correct set before you order.
Progressive play at a joint, knocking when the attachment changes direction under load, and visible oval wear on a pin are the usual signs. Measuring play at each joint tells you which positions are due — each has its own part number in the table above. In this group, LB12B01026D1 is the number most often quoted for that enquiry.
Yes. Send the serial number and which joints are loose, and we assemble the pin, bushing and hardware list into one quotation with everything consolidated into a single shipment.
They are the catalogue quantities per assembly — the number of that item fitted to one complete group, which is exactly how a rebuild order is planned.
