CAT 085-6790 RETAINER

CAT 085-6790 (0856790) is a Caterpillar genuine axial positioning retainer (elastic retaining ring) for construction machinery bearings. It is compatible with 259D3/279D3 skid steer loaders and 906H/907H mini excavators, used for axial positioning and anti-loosening of 085-6723 double-row angular contact ball bearings. It prevents axial movement of the bearing at boom joints, connecting rod hinge points, etc., ensuring stable operation of components. Cat®…

Compatibility and Application

Compatible Parts: 259D3/279D3 Skid Steer Loader, 906H/907H Mini Excavator, boom joint, connecting rod hinge points of the working device 085-6723 Double-row angular contact ball bearing, used for axial positioning and anti-loosening, preventing axial movement of the bearing, ensuring precise positioning and smooth operation of components, suitable for frequent load-changing operations such as excavation and loading (Cat®…).

Application Scenarios: Suitable for frequent load-changing operations such as excavation and loading, such as continuous excavation and shoveling operations, ensuring smooth operation of boom joints, connecting rod hinges, etc., preventing component loosening and wear, reducing the risk of failure, and improving operational safety and reliability (Cat®…).

Compatible Use: Used with 085-6723 bearings and 083-5020 adjusting rings. The retainer achieves axial positioning of the bearing, and the adjusting ring controls the bearing clearance, suitable for long-term high-frequency vibration operations, preventing component fatigue damage (Cat®…).

Installation and Maintenance Points

Installation: Clean the mounting slot and check dimensional tolerances; use retainer pliers to insert the retainer into the mounting slot on the shaft, ensuring it is fully engaged and secure; after installation, ensure good fit with the 085-6723 bearing to prevent axial movement (Cat®…).

Maintenance: Check the retainer for deformation, loosening, and corrosion every 200 hours; replace immediately if damaged; avoid contact with water and dust to prevent corrosion from affecting the retaining effect (Cat®…).

Replacement: Remove the old retainer with retainer pliers and check the mounting slot for damage; verify the dimensions before installing the new retainer, and ensure it is fully engaged and secure (Cat®…).
