Title:
SHIM (KU-6973866320)
Description:
The Kubota SHIM (KU-6973866320) provides precise spacing and alignment between mechanical components, thereby ensuring smooth operation and reducing wear. In practice, technicians install this thin metal spacer to eliminate unwanted gaps and maintain correct tolerances in moving assemblies.
First, the shim sits between two components—such as a pin, linkage, or joint surface—to control spacing. By doing so, it prevents excessive movement and misalignment.
Next, the shim distributes load evenly across contact surfaces. As a result, it reduces stress concentrations and minimises premature wear on pins, bushings, and joints.
In addition, the shim helps maintain correct alignment in pivot assemblies, especially in high-load areas like bucket linkages. Therefore, it improves overall machine stability and performance.
Moreover, operators can stack or combine shims of different thicknesses. This allows fine adjustments during servicing or repairs.
