Takeuchi TB108 Mini Excavator Parts Manual (BB5Z004-5-0) (SN 10810004- 1081200)
That TB108 lives in tight spots—backyards, inside buildings, around foundations—doing trenching, footing work, and cleanup where bigger machines just won’t fit. This parts manual helps you trace every assembly on the machine down to the nuts, seals, and snap rings, so you can order the right stuff the first time. Picture this: you’ve got the travel motor off, a mystery snap ring on the bench, and three similar ones in the catalog—this book lets you isolate the exact one by breakdown, location, and part number logic.
Applications & Use Cases
- Track down which sub-assembly a leaking seal belongs to, then verify you’re ordering the right seal kit instead of guessing.
- Trace the boom or blade setup, inspect what’s bent or cracked, and match each bracket or pin to the correct part number.
- When a track roller locks up, use the exploded views to test your teardown plan and check which bolts, shims, and seals you’ll need before you start.
- Align what you see on the machine with the diagrams so you can route hoses and cables correctly after a repair.
- Build a parts list for a full undercarriage or cylinder refresh and print it so the counter guy won’t mix up similar components.
FAQ
Q: Is this a PDF I can search on my laptop or phone?
A: Yes, it’s typically a searchable PDF, so you can jump to sections by keyword instead of flipping pages.
Q: Can I print just the pages I need for the jobsite?
A: You usually can; most folks print the relevant diagrams, throw them in a plastic sleeve, and keep the original file clean.
Safety Note
Always bleed off hydraulic pressure and support the machine securely before you start pulling any components the manual helps you identify.
