Part numbers as fitted to the Kobelco SK250-8 excavator. Where a position changed during the production run, the serial number settles which one applies to your machine.
The 15 entries group into 5 distinct number series, led by YN50C, YT50C. Expect repeated items such as rubber, plate, sems and 2 hardware positions when you work through it.
The high-quantity positions are: ZM66C06016 (sems-bolt, ×8 per assembly); YT50C01023P1 (rubber, ×4 per assembly); YT50C01012P1 (roller, ×4 per assembly). The full list follows below.
Cab fittings changed across the Kobelco SK250-8 production run. Send the machine serial number with your enquiry and we confirm the parts that match your build before quoting.
Cab and body parts are searched by description far more often than by number: a customer knows the glass is cracked or the seal is leaking long before they know the part number. That is why this page is built around the exploded view first — find the item on the drawing, note the callout, and take the matching part number from the table.
Both levels are available. Structural items exist as assemblies and every component — seals, latches, trim, glass — is listed individually, so you buy at whichever level suits the repair. If that matches your case, quote ZM66C06016 and we will take it from there.
Yes — all of them carry their own part numbers within this group. Small hardware is cheap to consolidate into an existing order.
Yes. Glass panels are listed as individual part numbers in the table above, so a windscreen, side glass or rear glass can be quoted without any surrounding hardware.
