Takeuchi TB015 Parts Overview

[MikePhua]

Machine Summary
The Takeuchi TB015 is a small, 1.5‑ton class mini excavator. It weighs around 3,307 lbs (1,500 kg), powered by a 3‑cylinder Yanmar engine putting out roughly 16 HP, and has a hydraulic system capacity of about 7.9 gallons (29.9 L).  With a relatively simple undercarriage (3 rollers per side) and low ground pressure (~4 psi), it is designed for tight‑space work like landscaping or utility trenching.


Here are some highlighted parts:

• Bottom Roller: A key undercarriage part, crucial for track support and smooth operation.
  
• Bucket Cylinder: Provides the force to move the bucket. Critical for digging or lifting.
  
• Arm (Dipper) Cylinder Seal Kit: Seals that wear over time and can cause leaks.
  
• Swing Cylinder Seal Kit: Seals for the hydraulic cylinder that powers the machine’s rotation.
  
• Bucket Cylinder Seal Kit: Another seal kit, more specific to the bucket’s internal hydraulic chamber.
  
• Rubber Track: Replacement rubber track for the TB015 — critical for maintaining traction and safe operation.
  
• Workshop & Parts Manual (Set): A physical set of manuals covering parts diagrams, maintenance, and repair.
  
• Service / Parts Manual PDF: Digital version of the parts manual, very useful for reference on the go.
  

Other Notable Parts
Beyond the products listed:

• According to AMS Parts, there are bearing kits for the final drive, track adjuster yoke and seal kits, sprockets, cylinder kits, and even wiring harnesses for the TB015.
  
• For attachments, you can get buckets, thumbs, and pins/bushings from specialized suppliers. One vendor lists parts like a drainage V-bucket, hydraulic thumb, and track links specifically for the TB015.
  

Common Failure Points & Part Replacement Advice

• Final Drive Bearings & Seals: A known issue is wear in the final drive bearings—TB015 uses 403 mm bearings and paired brass bushings with an O-ring. Replacing these can be expensive, but necessary to avoid final-drive failure.
  
• Hydraulic Leaks: Over time, cylinder seal kits for boom, stick, bucket, or swing are common maintenance items. Regular replacement prevents leaks, maintains performance, and avoids contamination.
  
• Track Wear: The rubber track is wear item No. 1 on a compact excavator. Choosing the right pattern (L‑tread, D‑tread) and quality material helps extend life.
  
• Robust Documentation: Having a service manual or parts manual (physical or PDF) is extremely helpful for DIY maintenance, diagnostics, and ordering the correct part numbers.
  

Where to Source TB015 Parts

• Aftermarket Retailers: Sites like AMS Parts carry a broad TB015-specific inventory.
  
• Specialized Mini‑Excavator Sellers: For buckets, track links, or undercarriage parts, mini-excavator‑focused sellers are often the best bet.
  
• Manuals and Diagrams: Downloadable workshop and parts manuals (e.g., 328-page TB015 service manual) are available and invaluable for repair work.
  

Pro Tips for Maintenance & Parts Management

• Keep a consumables inventory: Seals, O-rings, and filters: replace them as part of your service schedule.
  
• Track usage hours: The TB015 specs are modest in capacity, but undercarriage wear and hydraulics still benefit from preventive maintenance.
  
• When doing major undercarriage or drive train work, replace in matched sets (bearings, bushings) to avoid uneven wear.
  
• Use the parts manual to cross-reference old part numbers—TB015 has been on the market for decades, and parts have evolved.
  

Conclusion
The Takeuchi TB015 is a very serviceable small excavator. Major maintenance parts—hydraulic seals, undercarriage components, bearings, tracks—are still available through aftermarket suppliers. To keep one running reliably, you should invest in the correct seal kits, monitor undercarriage wear, and maintain a detailed parts manual. With the right maintenance strategy, a TB015 can remain productive for many years in routine mini-excavator work.
