Abstract: A method and apparatus is presented for harnessing power or force in a gear box or engine utilizing the power unit from the fulcrum of a lever in rotary motion. In accordance with the fulcrum gear assembly of the present invention, a first input gear is rotated in one direction and a second input gear is rotated in the other direction. The forces generated by the first and second gears are combined by third and fourth gears. The combined rotary forces are transferred to an output gear providing an output available on an output shaft. The output shaft being defined as a fulcrum results in a net gain in the rotary forces. Accordingly, the output of the fulcrum gear assembly is greater than the sum of its inputs.
