Restores smooth rotational movement and helps reduce uneven wear in linked components. Direct replacement: Matches the part numbers 3T4615, 3T4616, 1174013, and 5P7802 for direct fit and straightforward installation in the listed tractor models. Compatibility: Suited for use with Caterpillar models 578, 589, 725, 730, D350E, D350E II, D400E, and D400E II. Use the part numbers to confirm fit before installation. Durability and performance: Engineered for heavy equipment applications where bearings must handle variable loads and slight shaft misalignment. Designed to maintain alignment and reduce friction under typical field conditions. Ease of maintenance: Replacing a worn self aligning bearing restores component alignment and can simplify future maintenance by preventing premature wear on related parts. Why customers need this part Fixes vibration and steering or linkage play caused by worn bearings. Restores correct rotation and load transfer for components that depend on aligned shafts. Allows continued use of existing components without need for more extensive repairs when a worn bearing is the root cause. Key attributes Function: Self aligning bearing that compensates for angular misalignment between shaft and housing. Part numbers: 3T4615, 3T4616, 1174013, 5P7802 for accurate identification. Compatibility: Listed for use with the specific Caterpillar tractor models above. Confirm compatibility by matching part numbers and machine model. Performance: Designed for heavy equipment duty cycles to reduce friction and wear and to preserve alignment under load. Form factor: Intended as a direct replacement bearing for the referenced part numbers and equipment interfaces. Typical applications and use scenarios Routine maintenance: a worn bearing in the pivot arm or linkage on a Caterpillar 578 or 589 to eliminate play and vibration. Equipment refurbishment: During overhaul of a 725 or 730 machine, install this bearing as a direct replacement to restore correct shaft alignment and reduce future wear on mating parts. Field repairs on articulated tractors: Use the bearing to steering or drive shaft assemblies on D350E, D350E II, D400E, or D400E II tractors where misalignment or bearing wear is causing performance issues. Installation and fitment notes Verify fit by matching the part numbers 3T4615, 3T4616, 1174013, or 5P7802 to your machine parts list before ordering. Proper installation and alignment are important for bearing life. Follow equipment manufacturer guidance or consult a qualified technician for fitment and torque specifications. Inspect mating shafts and housings for damage or excessive wear before installing a bearing to prevent premature failure. This self aligning bearing is intended as a direct replacement for the listed part numbers on the noted Caterpillar tractor models and is designed to restore alignment and reliable rotation in heavy equipment applications.
