277-8664 Hoe Bucket Tooth — Cat 424B 424B2

This hoe bucket tooth is a wear part designed to penetrate and break up soil, rock, or other materials during excavation operations. Manufactured from hardened steel, it offers superior abrasion resistance compared to a worn or chipped tooth, ensuring efficient digging performance. Operators will observe reduced digging efficiency, increased wear on the bucket lip, and potentially a rougher ride when this tooth is significantly worn or broken.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

Reduced digging penetration and slower cycle times are the initial indicators of a worn hoe bucket tooth. As the wear progresses, the bucket may slip on harder surfaces, and the bucket lip will experience accelerated wear. Continued operation with severely worn teeth can lead to inefficient operation and potential damage to the bucket structure.

Installation Tip

Ensure the tooth adapter on the bucket is clean and free from debris before installing a new tooth. Do not attempt to force a tooth onto a damaged or worn adapter, as this can lead to improper seating and premature failure.

Service Note

Inspect the bucket lip and adapter for cracks or excessive wear when replacing a hoe bucket tooth.
