Compatible Machine Models: CAT 259D3/279D3 Skid Steer Loader, 906H/907H Mini Excavator

Matching Relationship: Used with 085-3602 Bearing, 085-3625 Bearing Assembly, 083-5020 Adjusting Ring

Compatibility and Application
Compatible Parts: 259D3/279D3 The 085-3602 bearing and 085-3625 bearing assembly are used for axial positioning and anti-loosening at the boom joint and connecting rod hinge points of skid steer loaders and 906H/907H mini excavators. This prevents axial movement of the bearings, ensuring precise positioning and smooth operation of components, and is suitable for frequent load-changing operations such as excavation and loading (Cat®…).

Application Scenarios: Suitable for frequent load-changing operations such as continuous excavation and shoveling, ensuring smooth 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 Use: Used with the 085-3602 bearing, 085-3625 bearing assembly, and 083-5020 adjusting ring. 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.

Installation and Maintenance Points

Installation: Clean the mounting slot and check dimensional tolerances; use retaining ring 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 085-3602 and 085-3625 bearing assemblies to prevent axial movement.

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 fixing effect.

Replacement: Remove the old retainer with retaining ring pliers and check the mounting slot for damage; verify the dimensions before installing the new retainer, and ensure it is fully engaged and secure after installation.
