Description
Overview:
This Bush (Position 10) is a non-genuine replacement part for Kubota KX057-4 mini excavators, engineered to replace OEM reference RD458 66770. It is a robust metal sleeve designed to support a pivot pin and provide a smooth, controlled bearing surface at a linkage point. By restoring the correct clearance at wear points, it helps reduce play, vibration, and uneven movement, keeping the machine responsive and accurate. The bush has a precision-machined form to suit the designated housing and pin interface on Kubota KX057-4 and KX0574 machines. It is suitable for routine maintenance or repair when the original bush shows signs of wear, scoring, or ovality, helping to maintain efficiency and extend the service life of associated pins and joints under demanding site conditions.
Key Features:
- Non Genuine Part compatible with Kubota OEM RD458 66770
- Durable metal construction for long service in harsh environments
- Precision-machined bore and outside diameter for a reliable, direct-fit replacement
- Helps restore tight clearances and smooth rotation at pivot points
- Designed to withstand high loads and shock typical of excavation work
- Smooth internal surface to minimise friction and reduce pin wear
- Straightforward installation and removal with standard workshop tools to limit downtime
- Suitable for planned maintenance to prevent accelerated wear of pins and housings
Typical Applications:
Used at pivoting joints on Kubota KX057 series mini excavators to support pins in linkages and moving assemblies. Commonly fitted during overhaul of worn joints to recover accurate movement and reduce noise. Ideal for preventative maintenance schedules where consistent digging, grading, or lifting performance is required on site, in hire fleets, or for owner-operators.
