Read as a dataset, the 14 part numbers spread across 8 number series (YN12B, B16T, YN02B being the biggest) The list is weighted toward repeated items such as shim, arm, instal and 4 hardware positions.
Where to start in this table: YN02B01414D1 (shim (2.0), ×2 per assembly); ZN18C20016 (nut, ×2 per assembly); YN12B20075F1 (arm instal, ×1 per assembly). The full list follows below.

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.
On several Kobelco SK240-12 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.
