2343930
for CAT
Product Name: Pin / Connecting Rod Pin / Bucket Linkage Pin / Bucket Pin
Part Number: 2343930 (also written as 234-3930, CA2343930)
Brand/Compatibility: Suitable for Caterpillar
Type: Bucket Linkage Pin (commonly used in bucket, stick linkage, and linkage mechanism connection points; a high-load, wear-resistant part)
Weight: Approximately 25–30 kg
Material: High-strength alloy steel (such as 42CrMo or 40Cr), surface hard chrome plating, heat-treated with quenching + tempering + induction hardening, possessing high hardness (surface HRC 55–60+), fatigue resistance, and corrosion resistance, suitable for heavy-duty excavation operations.
Function and Location:
Mainly installed at the connection point between the excavator bucket and the link/linkage, or the stick/dipper, or the bucket cylinder pin joint.
It connects, supports, transmits excavation force, and facilitates rotation, making it a core load-bearing component of the excavator's working device.
After prolonged high-intensity operation, wear, increased clearance, abnormal noise, or pin bending may occur. It is recommended to inspect/replace it along with the matching bushing and dust seal.
During installation, the matching bushing, oil seal, and dust cover must be replaced simultaneously, and appropriate grease should be used to avoid dry friction and accelerated damage. Installation by a professional technician using a press/alignment tool is recommended.
Applicable Models:
Caterpillar:
- 320C, 320C L, 320D, 320D L, 320D LRR, 320D RR, 320E, 320E L, 320E LRR, 320E RR

Product material
High-strength alloy steel: such as 40Cr, 42CrMo, etc. It has high strength, high toughness and good wear resistance. It can withstand the huge pressure and impact force of the rocker arm connecting arm when the excavator is working, ensuring reliability and stability under complex working conditions.
Surface treatment material: In order to improve the corrosion resistance and wear resistance of the pin shaft, surface treatment is usually performed, such as hard chrome plating and blackening. Hard chrome plating can form a hard and smooth chrome layer on the surface of the pin shaft, which can not only improve wear resistance, but also effectively prevent corrosion; blackening treatment forms a black oxide film on the surface of the pin shaft, which plays a certain role in rust prevention and can also improve the appearance.
