CAT 094-7732 RETAIN LOWER

CAT 094-7732 (0947732) is a special lower retaining ring for Caterpillar hydraulic pump/motor bearing cavities. It is used for axial positioning of the bearing outer ring bottom, preventing axial movement of components and seal failure caused by vibration. It is suitable for the power transmission systems of medium and large excavators and loaders, ensuring stable operation.

Core Parameters

Item Details
Part Model CAT 094-7732 (0947732) Lower Retaining Ring

Type: Lower retaining ring for axial positioning of bearing cavity, restricting axial displacement of bearing outer ring, preventing axial movement

Material: 65Mn spring steel, tempered and phosphated, good elasticity and fatigue resistance, hardness HRC42-46, wear-resistant and corrosion-resistant

Key Dimensions: Inner diameter approx. 148mm, outer diameter approx. 168mm, thickness approx. 6mm, suitable for bearing outer ring bottom mounting dimensions, single weight approx. 1.2kg

Compatible Models: CAT 330, 336 excavators, 972, 980 loaders, suitable for hydraulic pumps, travel motors and gearboxes of C9.3/C13 engines

Matching Relationship: With upper retainer (e.g.) (094-7111) Bearings and end caps are matched and installed in pairs, providing axial positioning and anti-loosening effects.

Suitable for:
Bottom of hydraulic pump bearing housing, below the end cap of travel motor, bottom of gearbox bearing chamber. Installed at the bottom of the bearing outer ring, it axially locks the bearing outer ring, preventing axial movement of the outer ring and loosening of the end cap caused by vibration, protecting seals, and reducing leakage risk.

Application scenarios: Mining, large-scale earthmoving, heavy-duty hoisting, and other severe vibration conditions. Suitable for medium and large equipment power systems, extending bearing and seal life and reducing failure frequency.

Core functions: Limits axial displacement of the bearing outer ring, ensures coaxiality of operation, counteracts vibration impact, prevents end cap loosening and seal failure, and maintains stable operation of the hydraulic/transmission system.

Installation and maintenance points:
Installation: Clean the mounting surface, confirm that the retaining ring fits snugly against the bearing outer ring and end cap, without deformation or burrs, and check for axial movement after installation.

Maintenance: Check the retaining ring every 250 hours for deformation or wear; replace immediately if any abnormalities are found. Regularly check the temperature and unusual noises of related components; disassemble and repair if abnormalities are detected.

Replacement: Prioritize original parts; verify model and dimensions. After installation, test the power system to ensure it operates normally, without unusual noises, leaks, or looseness.
