Listed for the Kobelco SK330-8 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.
Read as a dataset, the 13 part numbers spread across 5 number series (YN25M, YN12P, ZM27C being the biggest) In practice that means repeated items such as clamp, arm, rest and 4 hardware positions.
Three numbers worth noting first: ZM27C08025 (sems-bolt, ×4 per assembly); ZW26K06000 (lock washer, ×4 per assembly); ZS28C06020 (capscrew, ×4 per assembly). The full list follows below.
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.
The Arm Rest group on the Kobelco SK330-8 contains 13 separately orderable part numbers. The table below lists each one with its quantity per assembly, taken directly from the machine's own parts catalogue.
Yes — we cover the Kobelco range beyond the Kobelco SK330-8. Send the model or the part number from the worn part and we will identify and quote it. On the Kobelco SK330-8, that usually comes back to ZM27C08025 (sems-bolt) in this group.
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.
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.
