Takeuchi TS70V Skid Steer Loader Service Manual (7006-200)

Takeuchi TS70V Skid Steer Loader Service Manual (7006-200) (REV 111213)

Running a TS70V in dirt lots, demo rubble, or on frozen ground is hard on hydraulics and linkages, and this service manual is what we reach for when something doesn’t feel right. It walks you through how to trace a fault instead of just throwing parts at the machine. For example, if the loader arms creep down under load, this is the book we use to systematically isolate whether it’s a cylinder issue, a valve problem, or just a misadjusted control.

Applications & Use Cases

• Diagnose hydraulic issues by following test sequences to confirm if a problem is in the pump, valve, or actuator before replacing anything.
• Chase electrical faults using wiring logic to verify switches, relays, and sensors with a meter instead of guessing.
• Disassemble and reassemble major components in the right order so seals, bearings, and shims go back correctly.
• Set and verify adjustments on linkages, controls, and drive components so the machine tracks straight and responds smoothly.
• Plan parts replacement by confirming what actually failed and what should be inspected while you’re already torn down.

FAQ

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

A: Yes, it’s practical to keep it on a tablet or laptop so you can zoom diagrams and search terms while working next to the loader.

Q: Is it worth printing sections of this manual?

A: Many techs print the procedures they’re doing that day, so they can mark notes, keep greasy hands off electronics, and tape key pages right to the machine.

Safety Note

Always lock out, support, and relieve system pressure exactly as described before you loosen, disconnect, or test anything.
