Factory part numbers as fitted to the Kobelco SK250-8 excavator. "Ref." matches the callout number on the exploded view where one is shown.
The 21 entries group into 6 distinct number series, led by LQ21C, YN21C. In practice that means repeated items such as panel, insulation, rubber and 3 hardware positions.
Where to start in this table: ZN18C10008 (nut, ×12 per assembly); ZW26X10000 (lock washer, ×12 per assembly); 2418T12346 (washer, ×12 per assembly). The full list follows below.
The group runs from structural items that exist as assemblies down to individual seals, latches, clips and trim panels. Because both levels carry their own part numbers, you can scale the order from a single weather strip to a complete assembly without changing how you order.
Glass and panel orders are quoted with packing described on the quotation and freight shown separately, so the total landed cost is visible before the order is confirmed.
Yes — send the serial number and the scope, and we turn this group into a single quotation with everything consolidated into one shipment. In this group, ZN18C10008 is the number most often quoted for that enquiry.
Water ingress usually traces to a perished weather seal or a worn latch that no longer pulls the door tight. Find the seal and latch callouts on the drawing and take those numbers from the table; a photo helps us confirm.
Yes. Send the serial number and we will list every seal in the group into one quotation, consolidated into a single shipment.
