Caterpillar bucket tooth pins are used to secure the bucket tooth onto the adapter through the pin-and-retainer system. They are inserted through aligned holes in the adapter and tooth, then locked in place using a steel or rubber retainer (lock).
Installation Guide Overview:
- Insert the tooth onto the adapter tip.
- Align the through-holes.
- Slide the pin through the assembly.
- Lock the pin with a retainer on the opposite side.
Material & Surface Treatment
- Pin Material: High-strength alloy steel
- Hardness: After quenching & tempering: HRC 45–55
- Surface Coating: Anti-rust oil, phosphate or electroplating finish
- Retainer Options: Rubber ring locks, steel spring locks, or plate locks depending on pin type
Each pin undergoes precision turning, grinding, and strict tolerance control to ensure consistent locking and easy installation across batches.
Manufacturing Process
- Raw steel bar cutting
- CNC turning and groove machining
- Heat treatment (quenching and tempering)
- Surface polishing and rust protection
- Retainer fitment and inspection
