Part numbers as fitted to the Kobelco SK240-12 excavator. Where a position changed during the production run, the serial number settles which one applies to your machine.
Read as a dataset, the 129 part numbers spread across 26 number series (YN21C, LQ21C, YN22C being the biggest) In practice that means repeated items such as cover, guard, pillar and 21 hardware positions.
The high-quantity positions are: ZM73C12025 (sems bolt -, ×32 per assembly); ZM73C12030 (sems bolt -, ×13 per assembly); ZW16H12000 (washer, ×12 per assembly). The full list follows below.
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.
Cab comfort complaints — wind noise, water ingress, a door that no longer closes positively — trace to small items in this group more often than to the shell itself. Seals, latches and hinge hardware are worth checking before anything structural is ordered.
The worn or broken part from two angles, plus the machine data plate — those two together let us match the part number without a catalogue hunt. If that matches your case, quote ZM73C12025 and we will take it from there.
Glass travels crated, panels and trim boxed with edge protection. Freight is quoted separately and we ship to 30+ countries by air, sea or express courier.
Yes — send the serial number and the scope, and we turn this group into a single quotation with everything consolidated into one shipment.
