Order the wrong part and you lose days waiting on a return. This Kubota BX23D Parts Catalog PDF (OEM #11089) exists to stop that: 285 pages pinning down the exact factory number for every component, from diesel engine internals to the three-point hitch linkage. Roughly 100 pages are itemized parts lists, backed by exploded-view diagrams for engine, drivetrain, chassis, and hydraulic assemblies, plus oil line schematics for the suction, delivery, and steering circuits. HST transmission internals, front differential, rear axle, control valve parts, PTO shafts, the full steering cylinder breakdown: each major system gets its own callout. Injection pump shim stock lists at 0.20mm, the crankcase assembly at 32 kgf. Those numbers confirm you're holding the right part, not the one that almost fits. Bookmarks drop you onto your system on any device.

Kubota BX23D Common Problems This Manual Covers
Kubota BX23D won't start, need correct starter relay and solenoid part numbers to order p. 99
Pull the exploded views on pages 99 and 101. The Starter section lists the main starter assembly parts; Starter [Component Parts] breaks out the solenoid and internals individually. Match those part numbers against the Panel Board diagram on page 105 to pin down the relay positions, then confirm the 15A, 20A, and 30A fuse ratings on page 117 against what you pull from the fuse block before ordering.
Manual Section: StarterKey switch part number needed, intermittent no-start after electrical work p. 107
Find the key switch in the Switch/Sensor section, which starts on page 107 and covers the switch, sensors, and associated hardware. Cross-reference the Electrical Wiring diagram on page 116 to confirm the correct connector and harness part numbers for your serial range before you order.
Manual Section: Switch/SensorFuel shutoff stop solenoid part number unclear, tractor dies or won't start p. 92
Head to the Stop Solenoid section on page 92, where the exploded view lists the solenoid assembly and mounting hardware by individual part number. If the same order needs connected fuel line fittings, check the Fuel Pipe diagram on page 84 and Fuel Tank on page 82.
Manual Section: Stop SolenoidTransmission filter screen location unknown, need part number for HST maintenance p. 124
Open the Transmission Case section on page 124. That diagram covers the HST, clutch shaft, output shaft, and internal components; locate the filter screen in the parts list and note its number. The Rear Axle Case on page 126 adds context if the screen is reached from that side of the housing.
Manual Section: Transmission CaseWiring harness part number needed after damaged connector found during inspection p. 116
Check the Electrical Wiring section on page 116, which maps the full harness routing and lists each harness assembly by part number. Note the fuse ratings on page 117 (15A, 20A, 30A) while the panel is open, and use the Panel Board on page 105 to locate any damaged connector positions.
Manual Section: Electrical WiringBattery cables and terminal hardware part numbers needed for voltage-drop diagnosis p. 103
Reference the Battery section on page 103. The exploded view lists the battery, cable assemblies, and terminal hardware by part number. Trace the positive cable to the starter using the Starter diagram on page 99, then follow the ground path and junction points through Electrical Wiring on page 116.

Document Quality
This document is a scanned PDF with an OCR layer, enabling you to search and copy text from the instructions and parts lists. However, numbers directly on the parts diagrams are embedded as images and are not searchable. Text quality is consistently crisp and easy to read across all pages. The diagrams and illustrations are clear raster images, with all labels remaining fully readable. Pages are clean, free from significant scan artifacts, stains, or skewed content, and there are no blank or filler pages.
