2316854 Gear Gr - Swing Bearing — Cat 325B

This gear segment is a crucial part of the swing bearing assembly, enabling controlled rotation of the upper structure on excavators and other heavy equipment. Manufactured to meet stringent CAT quality standards, its precision-cut teeth ensure smooth engagement and durability, unlike a worn gear with chipped or rounded teeth. Operators may experience jerky or noisy swing operations, or a complete loss of swing function if this gear fails.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The first sign of a failing gear segment is often a rough or grinding noise during swing operations, accompanied by jerky movements. If the damage progresses, the swing function may become intermittent or completely unresponsive. Continued operation with a damaged gear can lead to further damage to the swing motor and bearing.

Installation Tip

Ensure the mating surfaces of the gear segment and swing bearing are meticulously clean before assembly. Avoid forcing the gear into place; it should mesh smoothly with the pinion.

Service Note

Inspect the swing motor pinion gear for wear or damage and check the overall condition and lubrication of the main swing bearing.
