Takeuchi TB108 Compact Excavator Workshop Manual (CB5E002) (SN 10820001-)

This TB108 workshop manual is what I’d keep open on the bench when working on a mini excavator that spends its life in tight landscaping jobs, trenching near foundations, and ducking around utilities. It walks you through how to strip, inspect, and correctly put back the major components so the machine tracks straight, digs clean, and doesn’t leak all over a finished yard. If, for example, the boom is drifting down or a final drive feels weak, this is the guide I’d use to trace the fault, test the hydraulic side, and verify the mechanical bits are reinstalled and adjusted properly.

Applications & Use Cases

• Tracing hydraulic problems like slow functions or drift by following a logical test-and-isolate sequence.
• Inspecting and resealing cylinders, valves, and lines after a hose burst or persistent oil leak.
• Verifying undercarriage work when you’ve changed tracks, rollers, or adjusted track tension.
• Guiding safe engine-side repairs, from basic removal to clean reinstallation and alignment checks.
• Confirming control linkages and pedals are routed, adjusted, and locking out correctly after cab or floor work.

FAQ

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

A: Yes, it’s practical on a tablet; you can zoom diagrams and keep your hands free while you work beside the machine.

Q: Is it worth printing sections of this manual?

A: I’d print the procedures you use often, slip them in plastic sleeves, and keep them in the service truck for dirty jobs.

Safety Note

Always lock out the machine, relieve hydraulic pressure, and support all raised components before starting any work.
