This 978-page Takeuchi TB175 workshop manual pdf covers the TB175 down to the fuel injection pumps, with dedicated sections for the YDP-MP2 and YDP-MP4 units. Open it and you get full hydraulic schematics for the pump, control valves, and cylinders, plus wiring diagrams covering the drive, slew, and control systems. A full troubleshooting section walks you from a dead travel motor or a slewing fault straight to the likely cause, and the torque tables back it up with real numbers. Set your hydraulic oil temperature between 50 and 60°C, and torque the coolant sensor to 4.9 N·m with ThreeBond 1104 on the threads. Your machine won't fix itself off a forum thread. Download it once, jump straight to any section with the bookmarks, and search any spec by keyword right from your phone in the shop.
