Kobelco SK200-10 · Boom Mounting — Group 2 · 12 part numbers
No illustration for this section
The Boom Mounting — Group 2 is listed without an exploded view in the SK200-10 catalogue — the parts table below is the authoritative reference, and every part number is confirmed against your machine serial before we quote.
The Boom Mounting — Group 2 group on the Kobelco SK200-10 contains 12 separately orderable part numbers. Callout numbers on the exploded view map one-to-one to the Ref. column in the table. The list comes straight from the Kobelco SK200-10 catalogue for this machine family.

Factory part numbers as fitted to the Kobelco SK200-10 excavator. "Ref." matches the callout number on the exploded view where one is shown.
Structurally, these 12 numbers fall into 4 Kobelco number series — YN02B, YN12B, ZS18C among the largest. The list is weighted toward repeated items such as shim, plate, boom and 2 hardware positions.
Where to start in this table: YN02B02515D1 (shim (2.9), ×2 per assembly); YN02B02515D2 (shim (3.4), ×2 per assembly); YN02B02515D3 (shim (3.9), ×2 per assembly). The full list follows below.
Undercarriage and structural wear is progressive: play at a joint, a knocking sound on direction change, oval wear on a pin. Because each position carries its own part number, worn positions can be replaced individually instead of ordering the complete group.
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.
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. In this group, YN02B02515D1 is the number most often quoted for that enquiry.
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.
They are the catalogue quantities per assembly — the number of that item fitted to one complete group, which is exactly how a rebuild order is planned.
