This bucket tooth is a wear component designed to penetrate and break up material during excavation, protecting the bucket edge. Manufactured from hardened steel alloys, it offers superior abrasion resistance compared to a worn or chipped tooth. A failing tooth may cause poor digging performance, increased fuel consumption, or damage to the bucket.

Failure Symptoms

The first sign of a worn bucket tooth is a noticeable decrease in digging efficiency and increased slippage. If ignored, the wear will accelerate, potentially damaging the bucket's cutting edge and adapter. Continued operation can lead to uneven wear across the bucket and reduced overall productivity.

Installation Tip

Ensure the tooth adapter and pocket are thoroughly cleaned of dirt and debris before fitting the new tooth. Do not attempt to force the tooth into place; it should seat firmly with proper alignment.

Service Note

Inspect the bucket adapter and locking pin for wear or damage when replacing the tooth.
