Part numbers as fitted to the Kobelco SK240-12 excavator. Where a position changed during the production run, the serial number settles which one applies to your machine.
The 18 entries group into 4 distinct number series, led by YT03M, YN03M. Expect repeated items such as grip, lever, plate and 2 hardware positions when you work through it.
The high-quantity positions are: YT03M01666P1 (boot, ×2 per assembly); YT03M01665P3 (plate, ×2 per assembly); YT03M01665P4 (plate, ×2 per assembly). The full list follows below.
Send the Kobelco SK240-12 serial number with the fault description. Machine-side electrical changed across the production run on some variants, and the serial number confirms the correct part before you order.
Electrical faults on the Kobelco SK240-12 — a gauge that will not read, a machine that will not crank, a harness rub-through — are diagnosed by circuit, and the fix usually comes down to one part number from this group rather than a complete rewire.
Yes — the harness is listed alongside its individual components, so you can replace a section or the complete assembly from the same table. If that matches your case, quote YT03M01666P1 and we will take it from there.
Send us the part number or a photo. Our coverage runs to 100,000+ part numbers available to order — this page lists one group, not the whole machine.
Yes. Connectors, relays and switches all carry their own part numbers in the table above, so a single connector repair can be quoted without a harness.
