A modified crank tool of a variable geometry turbocharger and a method for compensating for linkage abrasion are provided to obtain constant power by compensating for reduction of engine power caused by variation in a rotation angle of a vane through abrasion of a linkage. A modified crank tool of a variable geometry turbocharger comprises a rack gear(13) formed at an actuator rod of an actuator. A pinion gear(14) is fixed to an internal pin(15) such that the pinion gear engages with the rack gear. A vertical movement of the actuator is transferred to a crank tool through the rack gear and the pinion gear. Since the pinion gear is fixed to the internal pin, the pinion gear is meshed with the rack gear. As the pinion gear rotates, the internal pin rotates, so that displacement of an opening and closing angle of a vane is determined. |
