Factory part numbers as fitted to the Kobelco SK240-12 excavator. "Ref." matches the callout number on the exploded view where one is shown.
Read as a dataset, the 26 part numbers spread across 9 number series (YN42H, YY42H, ZD12A being the biggest) Expect repeated items such as clamp, tube, ring and 1 hardware positions when you work through it.
Where to start in this table: YN64H01392D1 (cap, ×26 per assembly); ZM73C12035 (sems bolt -, ×22 per assembly); YN43H01524P1 (bushing, ×8 per assembly). The full list follows below.
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.
Electrical diagnosis on the Kobelco SK240-12 starts with the circuit, not the part — but once the circuit is isolated, the fix is usually a single item from this group: a sensor, a relay, a connector or a short harness section.
Cranking-but-no-start traces through the fuel shut-off, sensors and relays in this group. Send the symptoms and serial number and we will indicate the likely part numbers. In this group, YN64H01392D1 is the number most often quoted for that enquiry.
Usually yes — a photo plus the machine serial number lets us match the connector or sensor against the catalogue.
Yes — the harness is listed alongside its individual components, so you can replace a section or the complete assembly from the same table.
