Description
Overview:
The 40x50x35mm Position 10 Bush is a precision‐machined metal sleeve designed for excavator linkages, including popular Kubota mini diggers such as the KX61-3 and KX71-3. It supports the pivot pin, reduces friction, and helps keep joints tight and accurate under load. The bush is designed to hold grease internally to minimise wear in abrasive, high‐duty environments. Sized at 40 mm internal diameter, 50 mm outer diameter, and 35 mm length, it is suited to press‐fit housings built to these dimensions. Marked as Position 10 on many diagrams, it is commonly used at a designated linkage point within the boom or dipper assemblies. Supplied to MPN 202 536, it offers a reliable replacement for worn or ovalised bushes to restore smooth operation.
Key Features:
- Metric size: 40 mm I/D x 50 mm O/D x 35 mm length for direct replacement fits
- Internally greased design helps reduce friction, wear, and maintenance intervals
- Precision‐machined for a snug press fit and accurate pin support
- Robust construction for sustained use in site conditions and repeated articulation
- Helps maintain pin alignment and reduce play in the linkage
- Compatible with common 40 mm pin applications where a 50 mm housing is used
- Smooth internal running surface to support consistent movement under load
- Suitable for routine overhaul of high‐wear joints on compact excavators
- Reference: Manufacturer Part Number (MPN) 202 536
Typical Applications:
Used in boom, dipper, and bucket linkage points on mini excavators during maintenance or rebuilds. Ideal when restoring tight tolerances after pins and bushes have worn, or when addressing joint play that affects digging accuracy. Common in workshop overhauls, on‐site repairs, and scheduled service intervals to keep compact diggers operating smoothly and safely.
