Takeuchi TS70R Skid Steer Loader Service Manual (7006-105)

Takeuchi TS70R Skid Steer Loader Service Manual (7006-105) (REV 111213)

On a TS70R that lives in mud, gravel, and demolition debris, this service manual is what I’d keep open when the loader won’t pull, the boom acts lazy, or an electrical fault keeps it from starting. It walks you through how to trace and isolate problems instead of just throwing parts at the machine. For example, if the hydraulics get weak after warming up, I’d use this manual to follow the test sequence, verify pressures with gauges, and confirm the real culprit before tearing into pumps or valves.

Applications & Use Cases

  • System diagnostics: Step-by-step checks to narrow down hydraulic, drive, or electrical faults.
  • Disassembly/assembly logic: Proper order to strip, inspect, and reassemble components so you don’t fight pins, seals, and linkages.
  • Adjustment guidance: Helps you set linkages, controls, and clearances so the loader tracks straight and lifts smoothly.
  • Verification before replacement: Procedures to test switches, sensors, and valves so you confirm failure before spending on parts.
  • Routine repair planning: Referencing torque patterns and sequences while you reseal cylinders or service drive components.

FAQ

Q: Can I use this manual on a tablet in the field?

A: Yes, it works well digitally; you can zoom diagrams and search terms while you’re next to the machine.

Q: Is it worth printing sections?

A: Many techs print just the procedures and schematics they need for a job, then keep those pages in a binder near the machine.

Safety Note

Always follow the manual’s lockout, support, and pressure-relief steps before loosening any fittings or removing components.
