Description
Overview:
The Bush (Position 10) for Kubota mini excavators is a non-genuine replacement part designed to restore smooth movement at critical pivot points. It replaces OEM reference RD458 66770 and is engineered for use with Kubota U48-4 and U484 machines. The bush is precision‐machined from a durable metal alloy to provide a stable bearing surface for the pin, helping to maintain alignment, reduce play, and protect the component housing from further wear. Suitable for routine maintenance or repair when the original bush has become worn or oval, it supports reliable operation in demanding site conditions. Its consistent sizing and clean finish aid fitting and help keep your excavator performing accurately during digging, grading, and lifting tasks.
