About this group

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

Read as a dataset, the 44 part numbers spread across 11 number series (LQ12B, YN12B, B16T being the biggest) In practice that means repeated items such as shim, arm, pin and 7 hardware positions.

Three numbers worth noting first: ZG91S02000 (nipple,grease, ×5 per assembly); ZN18C16013 (nut, ×4 per assembly); 2445R220D4 (seal,dust, ×4 per assembly). The full list follows below.

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.

Structural repairs are usually planned against measured wear rather than a fixed interval. Pins and bushings are the items to measure first; the retaining hardware in this group is cheap to replace at the same time and is worth adding to the same shipment.

FAQ

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

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. On the Kobelco SK250-8, that usually comes back to ZG91S02000 (nipple,grease) in this group.

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.

Can you quote a full pin and bushing kit for my machine?

Yes. Send the serial number and which joints are loose, and we assemble the pin, bushing and hardware list into one quotation with everything consolidated into a single shipment.
