About this group

Ordering the Arm Assembly,2.98M (9Ft 9In)

The 10 entries group into 3 distinct number series, led by LQ12B, YN12B. In practice that means repeated items such as arm, bushing, block.

The high-quantity positions are: YN02B01616P1 (block,tapped, ×4 per assembly); LQ12B01516P1 (bushing, ×2 per assembly); LQ12B01599P1 (bushing, ×2 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.

FAQ

Arm Assembly,2.98M (9Ft 9In) — common questions

Do structural parts differ between machine variants?

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 YN02B01616P1 and we will take it from there.

Do you stock undercarriage parts for other Kobelco models?

Yes — we cover the Kobelco range beyond the Kobelco SK250-8. Send the model or the part number from the worn part and we will identify and quote it.

How do I know which pins and bushings need replacing?

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.
