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.
The 51 entries group into 25 distinct number series, led by YT03M, LS03M. Expect repeated items such as control, box, bushing and 12 hardware positions when you work through it.
The high-quantity positions are: YT03M01816P1 (washer, ×10 per assembly); ZS18C08016 (capscrew, ×4 per assembly); YT03M01815P2 (washer, ×4 per assembly). The full list follows below.
Send the Kobelco SK260LC-12M serial number with your enquiry, and tell us which function feels wrong — that plus the serial confirms the correct parts from the table before you order.
Controls wear with use: levers develop play, linkages tighten up, and pilot circuits drift. Because each component in this group carries its own part number, worn positions can be replaced individually and the machine keeps its original feel.
They can — several control configurations existed on the Kobelco SK260LC-12M. The serial number plus the affected function confirms the correct parts. If that matches your case, quote YT03M01816P1 and we will take it from there.
Standard hand tools cover most of this group. We ship parts, not labour notes, but our team can point out which joints to check for wear while the linkage is apart.
Play in levers and linkages usually traces to worn pins and bushings in this group. Each position carries its own part number, so only the worn ones need ordering.
