Takeuchi TB350R Mini Excavator Workshop Manual (CJ6E010) (SN 150200007-)
Out on utility work, landscaping, or tight urban jobs, the TB350R spends its life digging, backfilling, and tracking over rough ground. This workshop manual is what I’d pull out when I’m doing proper repairs, not just quick checks. It walks you through how to strip, inspect, and correctly reinstall major components so the machine tracks straight, swings smooth, and doesn’t come back with the same fault. For example, if the house starts slewing unevenly or drifting, this is the book I’d use to trace the issue, verify clearances, and reassemble the swing gear and hydraulic components without guesswork.
Applications & Use Cases
- Planning a major repair on the undercarriage, boom, or swing system with a clear step‑by‑step sequence.
- Tracing hydraulic faults like weak functions or creeping cylinders and confirming what to test next.
- Inspecting wear points during scheduled services so you don’t miss seals, bushings, or hardware that should be replaced.
- Reinstalling components after teardown and double‑checking alignment, hose routing, and torque patterns.
- Verifying adjustments after control, travel, or attachment work so the machine responds correctly and safely.
FAQ
Q: Can I use this on a tablet in the field?
A: Yes, it works well on a tablet; you can zoom in on diagrams and keep it open next to the machine while you work.
Q: Is it worth printing sections of this manual?
A: I often print the pages for the specific job, mark them with notes or measurements, and keep them in a sleeve to avoid getting them oily.
Safety Note
Always lock out the machine, support raised components securely, and follow the manual’s cautions before loosening any pressurized or heavy parts.
