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 31 part numbers spread across 13 number series (YN52F, ZM73C, YN26C being the biggest) Expect repeated items such as plate, rubber, insulation and 9 hardware positions when you work through it.
If you are quoting from this group, start with: YN52F01100D3 (capscrew, ×32 per assembly); ZM73C10030 (sems bolt -, ×6 per assembly); ZM73C10025 (sems bolt -, ×6 per assembly). The full list follows below.
Items in this group are quoted with the condition declared — genuine through original supply channels, or a quality OEM alternative. For heavy sections the freight is quoted separately so you can see the landed cost before committing.
The Upper Frame Assembly group on the Kobelco SK240-12 contains 31 separately orderable part numbers. The table below lists each one with its quantity per assembly, taken directly from the machine's own parts catalogue.
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 YN52F01100D3.
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.
