  • Patent number: 7028721
    Abstract: A method and apparatus for filling a motor having a fluid dynamic bearing is provided. In one embodiment, a method for filling a motor having a fluid dynamic bearing having at least two passages coupling the bearing to the surrounding environment includes the steps of moving a fluid injection tool into contact with the fluid bearing motor, sealing the fluid injection tool to the fluid bearing motor, and injecting fluid from the fluid injection tool into a first passage coupled to the fluid dynamic bearing. In one embodiment, an apparatus for filling a motor having a fluid dynamic bearing having at least two passages coupling the bearing to the surrounding environment includes a body coupled to an actuator and fluid transfer mechanism. The actuator is adapted to move the body and fluid transfer mechanism is adapted to dispense fluid through a fluid port formed in the body. A seal is coupled to the body and adapted to seal the fluid port to a fluid bearing injection motor during filling.
