Abstract: A fixture for removing a rusted hub or collar from the end of a shaft, especially a fan from a motor shaft, comprises the following: a cylindrical body with a deep longitudinal groove adapted to accept the motor shaft in the center of the body (in such a position that the body axis and shaft axis are colinear); clamps to hold the shaft tight in the groove; hydraulic pistons in bores in the body, the pistons emerging from an end of the body adjacent the hub; and a plate attached to the exterior piston ends, for bearing against the hub. When pressurized fluid is admitted to galleries in the body, force is exerted upon the pistons, which force the plate against the hub. Since the body is clamped to the shaft, the hub is forced along the shaft and off the end. The invention is adapted to fit in the restricted space between a motor and a fan where ordinary tools cannot reach. The clamps may be simply screws threaded through the body to bear against the shaft within the groove.
