BEARING ADJUSTER RING (JLG JL980166)

A worn bearing adjuster ring can allow excessive play in rotating assemblies, leading to premature component wear. This aftermarket replacement part references JLG catalog number JL980166. The adjuster ring functions as a threaded component that sets preload on a bearing assembly. Its plain mechanical role is to compress or release the bearing by turning the ring to a specified torque. A common failure consequence is that an improperly adjusted ring causes bearing overheating or seizure during operation. Keeping the adjuster ring in sound condition helps maintain consistent rotational alignment under load. Verify the serial number or application, then call (562) 693-7748.
