Part of the Kubota Parts Manuals.
This is the Kubota BX23D parts catalog, an illustrated breakdown of the compact tractor loader-backhoe with exploded diagrams and the exact Kubota part numbers for every assembly. It matches factory publication number 100K0805 and covers the BX23D built from 2003 to 2009.
The catalog is organized by system, covering the engine, fuel, and cooling groups, the full electrical system (starter, dynamo, battery, wiring, switches, and lights), the transmission and HST, rear and front axles, steering, the hydraulic pump and lift components, plus wheels, labels, and accessories.
Use it to identify the right part before you order, confirm quantities and reference numbers, and understand how each assembly fits together. Serial number ranges and interchangeability notes are listed throughout all 285 pages so you can match parts to your specific machine.
