A compact torque converter tool having high mechanical advantages comprised of an input bevel gear having an axis colinear with the direction of drive, meshed with a further bevel gear having an axis transverse to the direction of drive, the further bevel gear having a gear member meshed to drive a gear driving a worm or helical gear with an axis transverse to the direction of drive but spaced therefrom, and an output gear coaxial with the input and has gear member meshed with the worm gear. The worm gear may also be driven by an input spur gear having an axis colinear with the direction of drive, meshed with a further spur gear that is coaxial with a helical thread gear that is meshed with another helical gear that is coaxial with the helical thread worm gear. The helical thread (or worm) on the worm gear can be oriented so as to drive a concave faced gear wheel (or worm wheel) in a selected direction.
