Abstract: A fixture has a body that connects to a motor, the body having a bore. The body has a piston in the bore, separating the bore into a pressure chamber and a lubricant chamber in fluid communication with lubricant in the motor. A technician applies pressure to the pressure chamber, which causes the piston to increase pressure of the lubricant in the lubricant chamber and in the motor. The technician monitors a distance of movement of the piston, indicating a presence of residual air in the lubricant. If the movement meets a amount, the technician applies a vacuum to the lubricant chamber and bleeds out residual air from the lubricant in the motor.
