The primary functions of bushings on a CAT 325B are:
Reduce Friction and Wear: The bushing is designed to be the sacrificial wear component. It protects the more expensive and harder-to-replace pins and linkage arms from direct metal-on-metal contact. When wear occurs, it's much more cost-effective to replace a bushing than a pin or an entire excavator arm.
Provide a Precision Fit: Bushings ensure a tight, precise fit between pins and their bores. This eliminates slop and free play, which is essential for the precise control needed for digging, lifting, and grading.
This 128-9864 bushing is used for 325B excavator.
