No illustration for this section
The Upper Frame Roller Assembly (SK260, SK310) 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.
Below is the complete Kobelco SK260LC-12M Upper Frame Roller Assembly (SK260, SK310) — 20 part numbers with the quantity fitted per assembly. Where the drawing shows a callout, the Ref. column in the table carries the same number. All numbers are taken from the machine's own parts catalogue — nothing here is generic.

Kobelco SK260LC-12M excavator part numbers, taken from the machine's own parts catalogue. Items shared with neighbouring machine generations are confirmed from your model plate before quoting.
Structurally, these 20 numbers fall into 9 Kobelco number series — LB64D, YN64D, ZD58F among the largest. Expect repeated items such as roller, shaft, bushing and 5 hardware positions when you work through it.
If you are quoting from this group, start with: LB64D01048F1 (roller assy, ×4 per assembly); LB64D01054F1 (roller assy, ×4 per assembly); YN52F01100D4 (capscrew, ×4 per assembly). The full list follows below.
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.
Where the attachment configuration differs — long boom, heavy-duty arm, alternative bucket — the pin and bushing numbers change with it. The serial number on the machine is the reliable way to pick the right line from this table.
If the boom, arm or bucket was changed after delivery, tell us the attachment part number as well as the machine serial — the numbers must match the attachment actually fitted. The practical first number to ask for in this group is LB64D01048F1.
On several Kobelco SK260LC-12M variants they do — pin and bushing part numbers changed with the attachment configuration. Send the serial number and we confirm the correct group before quoting.
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.
