The catalog is organized so a technician or parts manager can move from a system to a specific sub-assembly and find each component with its exact Komatsu part number, description, quantity per assembly, and the serial number range where each part applies. Each section opens with a detailed exploded-view illustration that numbers every component in the assembly, and the corresponding table lists the item number, part number, part name, quantity, and serial number applicability. This structure makes it possible to identify a single bolt or a complete sub-assembly without guesswork. The serial number breakouts throughout the document are especially important on the WD500-3, since several components were revised during the production run and using the wrong part number for your machine’s serial range will result in a part that does not fit.

Why This Parts Catalog Matters for Komatsu WD500-3 Owners and Workshops

Ordering the wrong part on a machine like the Komatsu WD500-3 wastes time and money. Serial number breakouts, mid-year revisions, and superseded part numbers make it easy to end up with a component that looks correct but will not fit or function. This catalog eliminates that risk by tying every part number to the specific serial range where it applies. Every table shows the exact Komatsu part number, and each exploded view shows precisely where the part belongs in the assembly, so the component is identified correctly the first time. For workshops maintaining a fleet of WD500-3 loaders, this parts catalog is the reference that keeps parts ordering accurate and downtime to a minimum. Parts managers can quote customers quickly and confidently, and field technicians can carry the relevant pages with them rather than relying on memory or guesswork.
