Compatibility and Application

Compatible Parts: 259D3/279D3 Skid Steer Loader, 906H/907H This device is used for axial positioning of 085-9657 needle roller bearings at the boom joint and connecting rod hinge points of mini excavators. It prevents axial movement of the bearing within the mounting holes, making it suitable for frequent load-changing operations such as excavation and loading.

Application Scenarios: For frequent load-changing operations such as excavation and loading, this device ensures stable operation of the boom joint and connecting rod hinge points, preventing component loosening and wear, reducing the risk of failure, and improving operational safety and reliability.

Compatible with: Used with 085-9657 needle roller bearings and 085-8823/085-8827 bushings. The retainer provides axial positioning of the bearing, and the bushing provides wear-resistant support, ensuring stable operation of the components.

Installation and Maintenance Points:

Installation: Clean the mounting slot and check the dimensions; use snap ring pliers to insert the retainer into the snap ring slot, ensuring it is fully seated and secure; after installation, ensure a tight fit with the bearing end face without gaps to prevent axial movement of the bearing.

Maintenance: Check the retainer for deformation, breakage, and corrosion every 200 hours, and replace it immediately if any problems are found; avoid heavy impacts that could cause the retainer to detach and prevent component damage.

Replacement: Use snap ring pliers to remove the old retainer and check the snap ring groove for damage; before installing the new retainer, verify the dimensions to ensure a tight fit with the snap ring groove without any looseness.
