2004–2005 Kubota BX23D Tractor & Attachment Parts Catalog Collection

These catalogs bring tractor and attachment parts identification together, with separate assembly indexes for each machine. Reference numbers link the illustrated components to part numbers, quantities and applicable serial-number or interchangeability notes.

This is a parts catalog collection, not a workshop repair manual: exploded views do not provide disassembly sequences, diagnostic tests or adjustment procedures. The mower catalogs carry BX1830/BX2230 references in their headings; they do not provide full tractor coverage for those models or installation instructions for fitting the decks to a BX23D.

Tractor Drivetrain, Loader Hydraulics and Mower Components

• Engine and fuel system: Exploded views identify crankcase, cylinder-head, piston, injection-pump and nozzle-holder parts, plus upper and lower gasket-kit contents.

• Drivetrain and brakes: HST component lists, PTO shafts, front and rear differentials, axle assemblies and brake components support replacement-parts identification.

• Steering and hydraulics: Steering-cylinder internals, hydraulic-pump components, control valves and suction, delivery and steering oil lines have illustrated parts references.

• Cooling and electrical equipment: Radiator, water-pump, thermostat, starter, dynamo and optional alternator sections accompany wiring-harness, switch and lighting parts lists.

• Loader and backhoe: LA210 valve configurations and cylinder components are separated from BT600 swing, boom, dipperstick, bucket and stabilizer assemblies.

• Mower decks: Separate catalogs identify universal joints, bevel gears, blade holders, belt-tension components, gauge wheels, discharge covers and mower linkage.

The collection suits owners and parts-counter staff who can match assembly callouts and serial-number notes to the equipment they are identifying.

Component Breakdown and Parts Selection

The BX23D catalog follows the tractor from internal engine components through the HST transmission and front axle to the frame, bonnet, seat and ROPS. Its assembly index provides direct routes to individual systems, while the parts tables distinguish complete assemblies from separately listed components.

Replacement compatibility: The introductory instructions explain serial-number inequalities, interchangeability symbols and country-code remarks. These distinctions help you check whether an updated part replaces an earlier version before preparing a repair parts order.

The “HST [COMPONENT PARTS]” view identifies pump and motor cylinder-block kits, swashplate components and relief valves. “PROPELLER SHAFT” includes the HST fan; this is a component reference, not a fan-failure diagnosis or transmission-rebuild procedure.

Loader and Backhoe Hydraulic Variants

LA210: Separate control-valve sections distinguish the BX2013 and BX2014 configurations and the later valve arrangement. Boom and bucket cylinder tables identify different heads, pistons and seal kits, with interchangeability restrictions that matter when selecting replacement components.

BT600: “SWING CYLINDER [COMPONENT PARTS]” distinguishes earlier and later rods, cushion pistons and seal kits. Separate spool-section drawings identify bucket, dipperstick, stabilizer, boom and swing valve components, while the hose illustrations show their respective connections.

Some catalog entries contain conflicting serial-number information, including an LA210 arm hydraulic tube and an RCK60B-22BX rear gauge wheel. Confirm those individual applications before ordering.

Always ensure the tractor is securely parked, completely powered down and depressurized before inspecting hydraulic pump components or fuel injection parts.

Mower Drive and Blade Identification

“INPUT SHAFT/CENTER PULLEY” and “PULLEY HOLDER/BLADE” identify the mower drive components and associated bearings, seals and retaining hardware. Separate deck catalogs distinguish blade, belt and gear-set part numbers, so similar-looking assemblies should not be assumed to use identical replacements.

Selected Piston Sizes and Mower Gear Sets

The BX23D piston-and-crankshaft table lists standard and +0.50 mm pistons and piston-ring assemblies. Crankpin bearing sets are listed in standard, -0.20 mm and -0.40 mm sizes. These are replacement-part size options, not wear limits or machining instructions.

For the mower input drive, RCK54-22BX bevel-gear kit K5761-33320 is listed as 16-19T, while RCK60B-22BX kit K5763-33320 is listed as 17-18T. The separate entries distinguish the gear sets used in the two decks.

Searchable Parts Tables and PDF Bookmarks

Parts lookup and navigation: Catalog text and part numbers are searchable, and embedded bookmarks link to all five catalogs and their assembly sections. The opening additional page has no searchable text. The “ELECTRICAL WIRING” illustration shows harness placement and parts callouts rather than an electrical circuit schematic.

Supplied as one printable, English-language, 504-page PDF, containing the five catalogs listed above plus one additional introductory page. Each catalog's listed page count includes its parts-book instruction page; all six introductory and instruction pages are already included in the total.
