A seized track roller or a weeping boom cylinder parks a mini excavator until the right part shows up, and this 292-page Takeuchi TB230 parts manual PDF (OEM ID BE8Z000-0-B) is how you get that number right the first time. Exploded views take the TB230 apart from the lower frame up: rubber and steel crawler belts, carrier and track rollers, front idler, track adjuster, travel device and slew bearing, then the cab, canopy, seat, decals and fuel piping. The hydraulic side fills the longest stretch of the book, with the control valve, pilot and solenoid valves, every work cylinder, travel motor, slew motor and hydraulic pump each broken down to callout and part number. Shims are listed by individual thickness (0.2 mm, 0.5 mm and 1.0 mm), so order the stack that matches what came out. A guessed shim is a fit nobody measured. Bookmarked by section and text-searchable, this parts catalog lets your order go in with the correct part number on the first call.

Takeuchi TB230 Common Problems This Manual Covers
Takeuchi TB230 travel motor reduction section thrust plate worn, need correct replacement part number and thickness
Check the travel motor exploded view on page 269 and match your worn plate against the parts list. The thrust plate is listed as part 1912905623 at t=1.8mm. Cross-reference the reduction and motor section seals, bearings, and gears on the same breakdown before ordering so one parts order covers the whole job.
Manual Section: Travel Motor p. 269Boom, arm, or bucket cylinder seal kit part number unclear when ordering packing and bushings
Check the cylinder exploded views starting, which cover the boom, arm, bucket, dozer, and swing cylinders. Identify the seal kit, piston, rod, bushing, and packing for your specific cylinder from its own parts list. Match the cylinder by its position on the machine before pulling numbers from the list.
Manual Section: Cylinder Repair (Boom, Arm, Bucket, Dozer, Swing)Track roller, carrier roller, or front idler worn out, need matching undercarriage part numbers
Check the Lower Frame chassis diagrams starting on page 16 for the crawler belt, crawler guide, carrier roller, track roller, front idler, and track adjuster. Identify each part by its callout number on the exploded view, then pull the part number from the matching parts list line. Order rollers and idler from the same breakdown.
Manual Section: Lower Frame p. 16Slewing device shims lost or damaged during teardown, need correct thickness and part number
