Description
Overview:
This Position 9&11 Bush is a precision-machined plain bearing used in the pivot points of compact construction machinery. Built from durable, wear-resistant steel, it supports the pin and reduces friction at high-load joints to keep linkages running smoothly. Sized at 35 mm inner diameter, 45 mm outer diameter, and 40 mm length, it is suited to housings and pins matched to these dimensions. Commonly installed at boom, dipper, bucket, or blade pivots, it is a direct fit for CAT 302.5-class mini excavators and related variants such as CAT3025. In typical parts diagrams it corresponds to positions 9 and 11 in the bucket or linkage assembly. Correctly fitted, it helps restore tight tolerances, minimise play, and extend the service life of pins and bores in demanding on-site conditions.
Key Features:
- Robust steel construction for long service life in abrasive, high-impact environments
- 35 mm ID x 45 mm OD x 40 mm length for accurate fitment to matching housings and pins
- Supports 35 mm pivot pins to reduce friction, wear, and ovality
- Precision-ground bore for smooth operation and consistent clearance
- Designed for press-fit installation into 45 mm housings
- Helps restore linkage accuracy and reduce bucket clatter and play
- Suitable for frequent articulation and shock loads seen on mini excavators
- Smooth-running support that protects pins and mating bores
- Stable geometry maintains alignment under load for improved component life
- Practical, service-friendly part for routine overhauls and preventive maintenance
Typical Applications:
Used at pivot points across mini excavator linkages, including bucket, dipper/stick, boom, and dozer blade assemblies. Ideal for replacing worn bushes during pin-and-bush overhauls on CAT 302.5-class machines. Suitable for workshop rebuilds or on-site maintenance to restore tolerance, reduce vibration and noise, and protect pins and housings from accelerated wear.
