Kubota RB411-66462 Pin

The Kubota RB411-66462 Pin is a precision-machined swing bracket pivot pin engineered specifically for use in the swing-frame assembly of Kubota U-Series mini excavators. This OEM pin provides the critical pivot point that allows the machine’s boom to swing left and right smoothly while maintaining structural stability and long-term durability.

Manufactured from hardened, high-strength alloy steel, the RB411-66462 is designed to withstand constant oscillation, heavy side loads, and the repeated shock forces produced during excavation, trenching, and utility work. Its precision-ground surface ensures a tight, consistent fit with the swing bracket and associated bushings, minimizing play and preventing premature wear of the surrounding components.

This pin is commonly replaced when excessive boom side movement, binding, or noise occurs—often caused by extended use or insufficient lubrication. As a genuine Kubota replacement part, it restores factory alignment, secure retention, and smooth pivot action, helping maintain the excavator’s original performance and safety standards.
