Kobelco SK240-12 · Boom Mounting (Boom Foot) · 9 part numbers
No illustration for this section
The Boom Mounting (Boom Foot) is listed without an exploded view in the SK240-12 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 (Boom Foot) group on the Kobelco SK240-12 contains 9 separately orderable part numbers. Callout numbers on the exploded view map one-to-one to the Ref. column in the table. All numbers are taken from the machine's own parts catalogue — nothing here is generic.

Factory part numbers as fitted to the Kobelco SK240-12 excavator. "Ref." matches the callout number on the exploded view where one is shown.
Structurally, these 9 numbers fall into 4 Kobelco number series — YN02B, YN12B, ZS18C among the largest. The list is weighted toward repeated items such as shim, boom, instal and 2 hardware positions.
Where to start in this table: YN02B02515D1 (shim (2.9), ×2 per assembly); YN02B02515D2 (shim (3.4), ×2 per assembly); YN02B02515D5 (shim (1.9), ×2 per assembly). The full list follows below.
The Boom Mounting (Boom Foot) group on the Kobelco SK240-12 contains 9 separately orderable part numbers. The table below lists each one with its quantity per assembly, taken directly from the machine's own parts catalogue.
Send the Kobelco SK240-12 serial number with your enquiry. Pin and bushing positions changed across the production run on several Kobelco SK240-12 variants, and the serial number is the fastest way to confirm the correct set before you order.
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.
