PART DESCRIPTION

The RG138-66660 Collar (15) is a genuine Kubota structural component used within the arm (boom/arm assembly) of select Kubota compact excavators. This collar functions as a precision spacer/bushing component, helping maintain correct alignment and spacing of arm pins and joints to ensure smooth articulation, reduced wear, and long-term durability of the arm assembly.

This part is utilized across multiple arm assembly groups (S08500, S09000, S09200, and G20000) depending on machine model and serial number range.
