Part of the Kubota Parts Manuals.
This is the Kubota illustrated parts catalog for the BX2230D compact tractor (publication 100K0782). It lays out every assembly on the machine as an exploded diagram paired with a numbered parts list, so you can identify the exact component and its Kubota part number before ordering.Coverage runs the full tractor: engine internals from crankcase to crankshaft, the fuel and injection system, cooling, the dynamo and starter, HST and transmission, front and rear axles, brakes, steering, hydraulics, and the electrical panel, lights, and wiring.Use it to cross-check part numbers against your serial number, tell interchangeable parts from superseded ones, and build an accurate order for engine, driveline, hydraulic, or electrical repairs on this 2004 to 2006 compact tractor.

Kubota BX2230D Common Problems This Manual Covers
Engine cranks but will not start
A no-start on the BX2230D usually traces to the fuel shutoff solenoid, fuses, relays, wiring, or the key switch. The stop solenoid diagram identifies the solenoid and its replacement part number.
Manual Section: Stop Solenoid p. 35Blown fuses or dead circuits
When lights, gauges, or accessories drop out, a blown fuse or failed circuit is the first suspect. The electrical wiring section shows the fuse ratings and harness layout for the tractor.
Manual Section: Electrical Wiring p. 108Faulty key switch or ignition
A worn key switch can leave the tractor dead or unable to shut off. The panel board diagram lists the switch and its Kubota part number for replacement.
Manual Section: Panel Board p. 98Overheating under load
Cooling trouble on these tractors often comes back to the water pump, thermostat, or radiator. The water pump exploded view identifies the pump, seals, and gaskets needed to reseal the cooling system.
Manual Section: Water Pump p. 62Weak or slow hydraulics
Loader and three-point actions that are weak or slow point to the hydraulic pump or its internals. The hydraulic pump diagrams break the pump down to individual components.
Manual Section: Hydraulic Pump p. 72Rough shifting or HST problems
Loss of drive or harsh engagement in the hydrostatic transmission sends you to the HST assembly. The exploded views identify the HST and its component parts for rebuild or replacement.
Manual Section: HST p. 118Frequently Asked Questions
What does this catalog cover?
It covers the complete Kubota BX2230D compact tractor: engine, fuel and injection system, cooling, electrical, HST and transmission, axles, brakes, steering, and hydraulics. Each system is shown as an exploded diagram with a matching numbered parts list.
Is this a repair manual or a parts catalog?
It is a parts catalog. It gives exploded diagrams, part numbers, quantities, and serial-number interchange notes to identify and order parts. It does not include step-by-step repair or torque procedures.
What is the fuel shutoff solenoid part number?
The stop solenoid section lists the replacement solenoid as part number 16851-60010. The exploded view shows how it mounts so you can confirm the correct part for your serial number. p. 35
What fuse ratings does the BX2230D use?
The electrical wiring section shows 15A, 20A, and 30A fuses. Matching the correct rating from the diagram avoids repeat blows and protects the circuit you are servicing. p. 108
