Every chapter above is presented as a numbered illustration with a matching table underneath it. The table columns give the item reference on the drawing, the Takeuchi part number, the part description, the quantity required per machine, interchangeability codes, the applicable serial number, and any service or remark note. Where a part is a sub-assembly, the components underneath it are marked with a star prefix, and nested assemblies use additional stars, so a buyer can see at a glance whether a bushing, seal or fitting comes separately or inside a larger assembly. Non-sellable parts carry an X prefix on the part number, which tells a counter clerk immediately that the item is only available as part of its parent assembly.

What This Takeuchi TB235 Parts Manual Lets You Do

Undercarriage work is covered in full: track roller sub-assemblies with shafts, floating seals, bearings, snap rings and stoppers; front idler assemblies with bushings and O-rings; track adjuster spring and grease cylinder assemblies with check valves and back-up rings; and both steel crawler and rubber crawler belt options with master pins, cotters and track pins listed individually.

The turntable and control section lists every lever, pedal, yoke, cable, boot, grip and bracket for the control lever and pedal assemblies, including the foot-switch variants, the proportional control variants, the 1st aux. ON-OFF types and the dozer blade lever. The corresponding hydraulic lines, adaptors, elbows, tees and cross fittings are listed with their O-rings, so a complete lever assembly can be rebuilt from the page rather than guessed at.

Engine and electrical pages cover the accessory side of the engine rather than its internal components – engine feet and cushion rubbers, radiator and oil cooler, hoses, bands, shrouds, guards, the air cleaner assembly with element, cover, valve and indicator, plus the battery, cable, terminal, clamp and switch. Electrical pages break out the main harness assembly with fusible links, diodes, fuse box and individual fuse ratings, the control unit with its relays, flip-flop units, timer unit, resistor, buzzer and diode units, and the separate control units for air conditioner, travel alarm, arm-in restriction, auto decel and cold-latitude heater.

Serial Number Ranges Matter With the TB235

Takeuchi changed components repeatedly across this machine’s build. The manual marks those changes directly in the part tables, so a serial number check before ordering prevents the most common wrong-part return. Examples visible throughout the book include the arm cylinder swap at 123500517, the cab mount change at 123500888, the boom change at 123500943, the hydraulic tank change at 123500517, the piping change at 123500973, and multiple fuel tank and fuel piping revisions at 123500325 and again at 123500613. Several assemblies also carry interchangeability codes – an H meaning the part replaces the row above it, an L meaning it replaces the row below – so a superseded number can be matched to the currently supplied one without a phone call.

Ordering the Right Part

Each table gives the quantity per machine, which matters for items like track roller bolts, bushing sets, dust seals, spring washers and clamp bands that are almost never ordered singly. Assembly-level items show the quantity for one complete assembly, which is the correct basis for a rebuild rather than a replacement. Grease fitting locations, adaptor and O-ring combinations, and shim thicknesses are all listed where the drawing calls for them, so a repair that needs a specific clearance can be shimmed correctly the first time.

Who This Takeuchi TB235 Parts Catalog Suits

Machine owners diagnosing a failed component and needing the exact part number before calling a supplier. Independent workshops rebuilding a travel motor, slew motor, hydraulic pump or cylinder and needing seal kits, bushings, slide rings and stoppers individually. Dealers and parts counters building a stock order across the whole machine. Restorers sourcing cab trim, decals, mirrors, grab handles, floor mat and painted colour codes. Anyone maintaining a mixed fleet of TB235 cab, canopy, angle blade and standard machines who needs to keep the correct variant straight.
