Features of the 42N-833-1390 Tooth

Bolt-on System: Quick and easy installation with bolts eliminates the need for welding, significantly reducing replacement time in the field.
High Hardness: Material hardness up to 52 HRC guarantees high resistance to abrasion in contact with sand, gravel, and rubble.
Bucket Protection: The tooth overlaps the blade, protecting it from wear and mechanical damage, extending the entire bucket's life.
Self-Sharpening Profile: The tooth shape is designed to maintain sharpness and ground penetration capability as the material wears down.

Application in machinery

Brand Machine Models
Komatsu / Fiat-Komatsu WB91R, WB93R, WB95R, WB97R, WB97S, WB98A, WB150WSC

The tooth is compatible with original Komatsu buckets adapted for bolt-on teeth (hole spacing should be verified).

Related Parts and Hardware

The tooth is mounted using plow bolts with nuts. We recommend replacing the bolts with new ones every time teeth are changed to ensure secure fastening (bolt hardness class min. 10.9).

⚠️ Safety Warning

Working with loose teeth leads to ovalization of the holes in the bucket blade. This can result in permanent damage to the bucket and the need for costly blade regeneration. Regularly check bolt tightness.

Part Role in the Machine and Failure Diagnostics

Bolt-on teeth serve as a replaceable cutting edge. They facilitate bucket penetration into the ground and protect its permanent structure.

  • › Rounded tip (digging difficulty, higher fuel consumption).
  • › Cracking at holes (effect of loose bolts or overload).
  • › Wearing down to the blade line (risk of bucket damage).
  • › Tooth loss during operation.

🔧 Expert Guide: Key Installation Tips

  1. Clean Surface: Before mounting, remove rust and dirt from the tooth-to-bucket contact area to ensure a flat fit.
  2. New Bolts: Always use new plow bolts of appropriate hardness (min. grade 10.9) and self-locking nuts.
  3. Tightening: Tighten bolts to the correct torque. Under-tightening is the main cause of tooth loss.

Frequently Asked Questions (FAQ)

Is this a central or corner tooth?

This is a central (symmetrical) tooth. Corner teeth (left/right) have a different shape, usually contoured to protect the bucket sides.

Do I need an adapter for this tooth?

No. This is a "unitooth" (monoblock) that bolts directly to the drilled bucket blade. It does not require welding adapters.
