Kobelco SK240-12 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.
Read as a dataset, the 9 part numbers spread across 8 number series (YN01F, YN63D, 2422T being the biggest) The list is weighted toward repeated items such as capscrew, low, group and 4 hardware positions.
If you are quoting from this group, start with: HS13F18050G1 (capscrew, ×24 per assembly); ZM73C12030 (sems bolt -, ×12 per assembly); YN63D00013P1 (guide, track, ×6 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. Pins, bushings and retaining hardware are all listed separately, so a single worn joint can be quoted on its own. The practical first number to ask for in this group is HS13F18050G1.
HD marks the heavy-duty version of the attachment, which uses its own pin and bushing part numbers that do not interchange with the standard version. Confirm which version the machine carries before ordering.
Yes — hardware is the cheapest line in the order and the most expensive to revisit, so a joint rebuild normally includes fresh clips, shims and bolts.
