Structurally, these 11 numbers fall into 9 Kobelco number series — LQ64D, YN64D, 2410N among the largest. The list is weighted toward repeated items such as roller, track, low and 2 hardware positions.

If you are quoting from this group, start with: 2420P1580D4 (capscrew, ×72 per assembly); LQ64D00029F1 (roller assy,track,low, ×18 per assembly); YN64D01020P1 (collar, ×2 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.
