Takeuchi TB014 Mini Excavator Parts Manual (BC4Z004-7-0) (SN 11400003-11401973)

That TB014 usually lives in tight spots—backyards, driveways, trench work around houses and utilities—where you don’t have room for a big machine. This parts manual helps you trace every assembly on that mini: boom, house, undercarriage, right down to the little seals and snap rings. Say you’ve got the track adjuster bleeding off and you’re not sure if you need the whole unit or just the rod seal; this lets you isolate the adjuster breakdown, verify part numbers, and order exactly what’ll fix it the first time.

Applications & Use Cases

• Track down the right snap ring or shim in the final drive by following the exploded view, instead of guessing at the counter.
• Check how the undercarriage is built up so you can route hoses and guards correctly after you pull the track frame.
• Verify superseded part numbers when the dealer’s system looks different, so you’re sure you’re getting parts that actually fit your serial range.
• Inspect a worn pin or bushing on the boom, then match it to the diagram to decide if you’ll replace just that piece or the whole linkage set.
• Isolate oddball brackets and covers when the machine’s half stripped, so everything lines back up on reassembly.

FAQ

Q: Is this a PDF I can search, or just scanned pictures?

A: It’s typically a searchable PDF, so you can jump by part name or section, though diagrams are basically images.

Q: Can I print just a few pages to take to the jobsite?

A: Yeah, you can usually print specific sections—most folks print the systems they’re tearing into so they don’t trash a laptop in the dirt.

Safety Note

Always lock out the machine, block raised components, and bleed off hydraulic pressure before you start pulling parts you’ve traced in the manual.
