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.
