Part numbers as fitted to the Kobelco SK250-8 excavator. Where a position changed during the production run, the serial number settles which one applies to your machine.
The 32 entries group into 14 distinct number series, led by LQ52F, YN52F. The list is weighted toward repeated items such as insulation, frame, upp and 7 hardware positions.
The high-quantity positions are: YN52F01100D2 (capscrew, ×32 per assembly); ZM73C10025 (sems-bolt, ×8 per assembly); YN52F01734P1 (insulation, ×3 per assembly). The full list follows below.
Send the Kobelco SK250-8 serial number with your enquiry. Pin and bushing positions changed across the production run on several Kobelco SK250-8 variants, and the serial number is the fastest way to confirm the correct set before you order.
Structural groups rarely fail as castings; what wears is everything pinned, bolted and clamped to them. That is what makes this group the practical one to work from — pins, bushings, retaining hardware and the mounting points that take the working load every cycle of the machine.
On several Kobelco SK250-8 variants they do — pin and bushing part numbers changed with the attachment configuration. Send the serial number and we confirm the correct group before quoting. If that matches your case, quote YN52F01100D2 and we will take it from there.
Yes — we cover the Kobelco range beyond the SK250-8. Send the model or the part number from the worn part and we will identify and quote it.
Progressive play at a joint, knocking when the attachment changes direction under load, and visible oval wear on a pin are the usual signs. Measuring play at each joint tells you which positions are due — each has its own part number in the table above.
