Abstract: The present disclosure relates to a coupling assembly for a variable displacement hydraulic unit. The coupling assembly may have a rotatable swashplate, a swashplate bearing including a cage and a plurality of rollers mounted on the cage, a pin fixed to the swashplate, and a coupling member rotatably supported on the pin. The coupling member is configured to contact a portion of the cage to move the swashplate bearing upon rotation of the swashplate
