CAT 093-1599 RETAINER

CAT 093-1599 (0931599) is a Caterpillar original equipment manufacturer (OEM) flexible retainer ring type retainer for articulation points of construction machinery. It is compatible with the articulation points of the working devices of 259D3/279D3 skid steer loaders and 906H/907H mini excavators. It is used in conjunction with 091-4462/092-5172 bearings, 090-9624 bushings, and 090-9289 retaining rings to axially position the bearings/bushings, preventing displacement during operation and ensuring stable operation of the articulated joint.

Core Parameters and Information

Compatible Models: CAT 259D3/279D3 skid steer loaders, 906H/907H mini excavators

Matching Relationship with Matching bearings 091-4462/092-5172, bushings 090-9624, retaining rings 090-9289, and dust rings 087-1873, for axial fixation of articulated joint assemblies.

Suitable for:
Suitable parts: Articulated joints of skid steer loaders, mini excavators (boom and frame, connecting rod and boom, etc.), installed in the pin groove to axially limit bearings and bushings, preventing axial movement of components under varying loads and vibration conditions, avoiding abnormal noise and wear.

Application scenarios: In complex outdoor working conditions such as excavation and loading, subjected to high-frequency vibration and impact loads, relying on elastic deformation to lock the pin groove, ensuring reliable fixation and easy maintenance.

Core functions: Axial positioning, anti-movement, ensuring accurate installation of bearings and bushings, improving the operational stability of articulated joints, and reducing maintenance frequency.

Installation and Maintenance Points

Installation: Clean the pin groove, use snap ring pliers to open the retainer, and smoothly insert it into the groove, ensuring it is fully engaged and secure. Assemble it sequentially with the bearing, bushing, retaining ring, and other components, ensuring the axial clearance meets requirements (usually 0.1-0.3mm) and that there is no jamming during operation.

Maintenance: Check the retainer every 200 hours for deformation, breakage, or loosening. Replace it immediately if any abnormalities are found to prevent damage to components due to bearing/bushing displacement.

Replacement: Remove the old retainer with snap ring pliers and check the pin groove for wear. Before installing the new retainer, verify its dimensions to ensure it matches the groove. After installation, test the hinge area to confirm there are no abnormalities.
