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.

About this group

Ordering the Guard Installation

Structurally, these 85 numbers fall into 15 Kobelco number series — LQ21C, YN21C, ZM73C among the largest. In practice that means repeated items such as guard, washer, cover and 18 hardware positions.

The high-quantity positions are: ZM73C12030 (sems-bolt, ×13 per assembly); 2418T10357 (washer, ×6 per assembly); YN21C03212P1 (stopper, ×4 per assembly). The full list follows below.

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 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.

FAQ

Guard Installation — common questions

Can you quote a full cab seal set?

Yes. Send the serial number and we will list every seal in the group into one quotation, consolidated into a single shipment. If that matches your case, quote ZM73C12030 and we will take it from there.

Do cab panels differ between machine markets?

They can, by build specification. The serial number identifies the build, and we confirm the panel numbers against it before quoting.

Will these parts fit my machine's serial range?

Cab fittings changed across the production run. Send the serial number with the part number and we confirm fitment before you commit to the order.
