How to Tell if Bucket Teeth Need Selection and Replacement?

一、35S Bucket Teeth Selection Criteria:

1、Machine Compatibility:

35S teeth are designed for 5-20 ton excavators. Verify compatibility with your machine model (e.g., CAT 320, Komatsu, PC200) and adapter (e.g., H-style shank)

2、Working Condition：

For soil/sand: Standard alloy steel (42CrMo) suffices. For rock/hard ground: Choose bimetal teeth with carbide tips.

3、Quality Certification:

Prioritize ISO 9001/CE-certified teeth with hardness ≥45 HRC and impact resistance

  Bucket teeth are critical wear parts for excavators and loaders. Over time, they wear out or break, affecting performance. Replacing them on time protects the bucket and improves efficiency. Here’s how to check if they need replacement:

1. Check Wear Level
Tip worn by 1/3 or more: If the tooth tip is flattened or shortened, digging efficiency drops—time to replace.
Base wear: If the tooth’s mounting area is worn, it may loosen or fall off.

2. Look for Cracks or Breaks
- Visible cracks, chipping, or fractures mean immediate replacement to avoid damage to the adapter or bucket.

3. Reduced Efficiency
- Increased digging resistance, higher fuel consumption, or slower loading may indicate worn teeth.

4. Unusual Noise/Vibration
- Loose or damaged teeth can cause metal clanking or abnormal vibrations during operation.

5. Regular Inspection
- Inspect teeth every 50-100 working hours—more often in harsh conditions (e.g., rock, hard soil).

Replacement Tips:
- Replace in pairs to ensure balanced force distribution.
- Choose high-quality teeth compatible with your machine for longer service life.
