Structurally, these 15 numbers fall into 5 Kobelco number series — YT25M, LP25M, ZS68C among the largest. In practice that means repeated items such as arm, rest, bracket and 5 hardware positions.

Three numbers worth noting first: ZS68C08018 (capscrew, ×4 per assembly); ZM73C08016 (sems bolt -, ×3 per assembly); ZS68C08035 (capscrew, ×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.
