Takeuchi TL220 Track Loader Workshop Manual (CU0E003)

Takeuchi TL220 Track Loader Workshop Manual (CU0E003) (SN 222000001_)

The TL220 is usually working in tight construction sites, landscaping jobs, and muddy yards where it’s constantly loading, grading, and pushing. This workshop manual is what I’d keep open when I’m tearing into major components and need the right order to strip, inspect, and reinstall without creating new problems. For example, if the loader starts creeping or won’t hold on a slope, I’d use this book to trace the issue through the drive system, verify adjustments, and reassemble everything so it tracks straight again.

Applications & Use Cases

Plan a full teardown of major assemblies with a logical sequence so you don’t miss hidden fasteners or seals.
Inspect and measure wear points on pins, bushings, and track components to decide what must be replaced now versus next service.
Trace hydraulic faults from the controls to the actuators, isolating leaks or weak functions before ordering parts.
Align and reinstall loader arms, cylinders, and linkages so the bucket sits level and cycles smoothly.
Verify adjustments after repairs—controls, travel, and safety interlocks—before handing the machine back to the operator.

FAQ

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

A: Yes, it’s practical to keep it on a tablet so you can zoom diagrams and search terms right next to the machine.

Q: Is it worth printing sections?

A: I’d print the procedures I’m using that day, mark them up with notes, and keep the clean master file on my computer.

Safety Note

Always follow the lockout, support, and pressure-release steps in the manual before opening any hydraulic or suspended component.
