Factory tolerances, fill quantities and fault logic for the Takeuchi TB15 compact excavator are settled in one place: this 272-page Takeuchi TB15 service manual PDF, the Workshop Manual issued as PUB. 1. Hydraulic schematics trace oil from the gear pump through the control valve to the travel and slew motors, and wiring diagrams map the electrical circuits you will chase with a meter. Roughly a third of the book goes to hydraulic unit overhauls covering the pump, control valve, slew counterbalance valve, travel motor and swivel joint, while the troubleshooting charts sort faults by function: travel, slewing, boom, arm, bucket, boom swing and dozer blade. Expect 7 cc/rev from each of the three gear pump sections, and fill each track roller with 40 cc of oil. One missing figure can stall a travel motor rebuild halfway. Bookmarked and text-searchable, your copy travels on a laptop or phone to whatever jobsite the TB15 is working.
