Takeuchi's own parts publication, identified by OEM ID PUB. 4, comes to you as a 230-page Takeuchi TB25 parts catalog PDF covering the TB25 and 250 compact excavators. Exploded views break each assembly into numbered components, from the crawler belt, track rollers, front idler and travel device underneath to the slewing device, control valves, selector valve and hydraulic pump in the hydraulic device section. Electrical pages set wiring diagrams beside the control box and engine control parts lists, so you can trace electrical components to an orderable part number. Spacing the blade? Pick from six collar thicknesses (1.0mm, 1.6mm, 2.3mm, 3.2mm, 4.0mm and 5.0mm), listed as part numbers 00030-30000 through 00030-30005. Perhaps your job is ordering parts for a boom cylinder, arm cylinder or travel motor, each broken out on its own plate. Bookmarks jump straight to any assembly. Search any part number and the text layer finds it.
