Listed for the Kobelco SK240-12 excavator. Every number can be quoted on its own or as a complete set, and fitment is confirmed from your machine serial before we price it.
The 44 entries group into 13 distinct number series, led by YN42H, ZD12P. Expect repeated items such as tube, clamp, ring and 9 hardware positions when you work through it.
Three numbers worth noting first: YN43H01524P1 (bushing, ×7 per assembly); ZD12A02100 (o ring -, ×6 per assembly); ZW16H12000 (washer, ×6 per assembly). The full list follows below.
Monitor and controller items vary by machine build, so the serial number matters more in this group than in most. Send it with the fault description and we confirm the correct variant before quoting.
Electrical items are quoted with the condition declared: genuine through original supply channels, or a quality OEM alternative. For sensors and switches, genuine is usually the practical choice, and the quotation says which is which.
Intermittent faults still end at a part number — send the symptom pattern and the serial, and we will suggest the positions in this group most often responsible. On the Kobelco SK240-12, that usually comes back to YN43H01524P1 (bushing) in this group.
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.
Usually yes — a photo plus the machine serial number lets us match the connector or sensor against the catalogue.
