Kinton Parts is trusted by professionals worldwide for delivering high-quality parts for excavators, bulldozers, and other construction machinery—with guaranteed performance and durability.
The bucket tooth pin is a critical wear component used to fasten the bucket tooth to the adapter securely. For Komatsu excavators, this pin not only prevents loosening during excavation but also absorbs part of the operational stress, extending the life of both the tooth and adapter.
Whether you’re working with rocky terrain, clay, or compacted soil, a reliable tooth pin ensures efficient power transfer and stable digging force.
Material & Heat Treatment
Each Komatsu bucket tooth pin is forged from premium-grade alloy steel. To enhance hardness and durability:
- Surface hardening (quenching and tempering) reaches HRC 45–52
- Precision CNC turning ensures straightness and consistent fit
- Black oxide or zinc coating available for corrosion resistance
These treatments help the pin withstand repeated impact and resist deformation under high shear loads.
Pin & Retainer Assembly Structure
This Komatsu tooth pin set typically includes:
- Pin body with recessed groove or flat locking face
- Rubber or metal retainer ring (spring-type or latch-style)
- End cap (if applicable) for enhanced anti-loss design
Installation is simple: insert the pin through the adapter and tooth holes, align the grooves, then press-fit the locking retainer. Removal is equally easy with basic tools.
