Illustration reproduced from the Kobelco SK250-8 parts catalogue for part identification only. Callout numbers on the drawing match the Ref. column in the table below. Kobelco is a trademark of its respective owner; Shenyue Machinery is an independent supplier of excavator parts.
The Kobelco SK250-8 Low Group (For Long Crawler) breaks down into 25 individually orderable part numbers. The Ref. column mirrors the callout numbers on the illustration, so a part can be ordered straight from the drawing.

Factory part numbers as fitted to the Kobelco SK250-8 excavator. "Ref." matches the callout number on the exploded view where one is shown.
The 25 entries group into 18 distinct number series, led by YN07F, LQ02F. Expect repeated items such as low, capscrew, guide and 6 hardware positions when you work through it.
Where to start in this table: 2420P2963D3 (capscrew, ×56 per assembly); YN01F01040P1 (cap, ×32 per assembly); ZS13C16045 (capscrew, ×30 per assembly). The full list follows below.
Where the attachment configuration differs — long boom, heavy-duty arm, alternative bucket — the pin and bushing numbers change with it. The serial number on the machine is the reliable way to pick the right line from this table.
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.
Yes — retaining rings, shims and bolts are all listed in this group, and a joint rebuild quotation includes them by default. In this group, 2420P2963D3 is the number most often quoted for that enquiry.
Yes. Pins, bushings and retaining hardware are all listed separately, so a single worn joint can be quoted on its own.
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.
