Listed for the Kobelco SK260LC-12M excavator. Every number can be quoted on its own or as a complete set, and fitment is confirmed from your machine serial before we price it.
Read as a dataset, the 14 part numbers spread across 9 number series (LB12B, B16T, LQ12B being the biggest) In practice that means repeated items such as shim, arm, instal and 4 hardware positions.
Three numbers worth noting first: YN02B01414D1 (shim (2.0), ×2 per assembly); ZN18C20016 (nut, ×2 per assembly); LB12B00313F1 (arm instal, ×1 per assembly). The full list follows below.
Rebuilding a joint takes the machine out of service once, so it pays to consolidate: pins, bushings, retaining rings and the joint seals quoted together, arriving as one kit rather than in several parcels.
Undercarriage and structural wear is progressive: play at a joint, a knocking sound on direction change, oval wear on a pin. Because each position carries its own part number, worn positions can be replaced individually instead of ordering the complete group.
Yes — we cover the Kobelco range beyond the Kobelco SK260LC-12M. Send the model or the part number from the worn part and we will identify and quote it. On the Kobelco SK260LC-12M, that usually comes back to YN02B01414D1 (shim (2.0)) in this group.
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.
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.
