Factory part numbers as fitted to the Kobelco SK200-8 excavator. "Ref." matches the callout number on the exploded view where one is shown.
The 48 entries group into 9 distinct number series, led by YN12B, B16T. The list is weighted toward repeated items such as shim, arm, pin and 6 hardware positions.
Where to start in this table: 2445R220D4 (seal,dust, ×6 per assembly); ZG91S02000 (nipple,grease, ×5 per assembly); ZN18C16013 (nut, ×4 per assembly). The full list follows below.
Send the Kobelco SK200-8 serial number with your enquiry. Pin and bushing positions changed across the production run on several Kobelco SK200-8 variants, and the serial number is the fastest way to confirm the correct set before you order.
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.
Yes — retaining rings, shims and bolts are all listed in this group, and a joint rebuild quotation includes them by default. In this group, 2445R220D4 is the number most often quoted for that enquiry.
Yes. Pins, bushings and retaining hardware are all listed separately, so a single worn joint can be quoted on its own.
HD marks the heavy-duty version of the attachment, which uses its own pin and bushing part numbers that do not interchange with the standard version. Confirm which version the machine carries before ordering.
