Takeuchi TB138FR Mini Excavator Parts Manual (BG5Z002-8-0) (SN 13810003-)
That TB138FR usually lives in tight spots—around foundations, in city streets, up against retaining walls—anywhere a full-size excavator just won’t fit. This parts manual helps you trace every component on that machine back to the exact part number, so when something cracks, leaks, or falls off, you can actually order the right bit the first time. Picture you’ve got the house rotated over the blade, boom tucked in, and you find a mangled track roller; this book lets you isolate that roller, verify which style you’ve got, and match it to the right assembly breakdown.
Applications & Use Cases
- Track down the exact snap ring or shim in the swing or travel motor by following the exploded view and part-number sequence.
- Check which undercarriage setup you’re running—steel, rubber, or rubber pads—before you order belts, rollers, or idlers.
- Verify hose routing and fittings so you can route new lines cleanly and test for leaks without guessing on thread types.
- Isolate small hardware—pins, bushings, seals—inside a larger assembly when you don’t want to buy the whole thing.
- Inspect wear parts on the bench and match them visually to the diagrams so you’re sure you’re replacing the right style for your serial range.
FAQ
Q: Is this a searchable PDF or just scanned pages?
A: It’s typically a PDF you can search by part name or number, but I’d still scroll the diagrams to double-check before ordering.
Q: Can I print just a few sections to take to the jobsite?
A: Yeah, you can usually print specific pages, toss them in a sleeve, and keep the greasy fingerprints off your laptop.
Safety Note
Always bleed off hydraulic pressure and support the attachment or boom mechanically before you start pulling pins or cracking lines.
