Structurally, these 73 numbers fall into 13 Kobelco number series — LC21C, YN21C, ZM73C among the largest. In practice that means repeated items such as guard, washer, plate and 15 hardware positions.

The high-quantity positions are: ZM73C12030 (sems-bolt, ×12 per assembly); YN21C03212P1 (stopper, ×4 per assembly); ZN18F10008 (nut, ×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.
