Published by Takeuchi under document number CN4E000, this Takeuchi TB2150 service manual PDF runs 422 pages and is the factory shop book for the TB2150 hydraulic excavator. Disassembly and assembly take up about a third of the book, covering the drive system, travel system, slew equipment, upper frame and attachments, and a troubleshooting section sorts faults by travel, slewing, boom, arm and bucket. Hydraulic schematics trace the pump, pilot valve and slew motor circuits, wiring diagrams lay out the electrical side, and the back holds the maintenance software manual plus air conditioner service. Check your sprocket against dimension A: 530.6 mm (20.9 in.) new, 524.6 mm (20.7 in.) allowable, then torque each 1/2 hose union nut to 58.8 ± 4.9 N·m on reassembly. Calling sprocket wear by eye wastes good steel. With section bookmarks and a searchable text layer, you can measure against the wear limits and order the right sprocket or rollers the first time.
