Articulation and Movement: Pins act as the rotating hinges at all major connection points. They allow for the precise and powerful articulation of the boom, stick (arm), and bucket, enabling the complex digging, lifting, and loading movements of the excavator.
Load Transfer: These pins bear and transfer the tremendous forces generated during operation. This includes the weight of the components themselves, the hydraulic forces from the cylinders, and the reactive forces from digging and lifting heavy materials.
This 489-6694 pin is used for 349F 349E excavator.
