Abstract
A method for attachment to an overhead crane for removing the bearing assembly from a vertical centrifugal pump system without removing the motor. The apparatus includes a rigid C-shaped frame which is attached by a pulley to an overhead crane and also includes a pivotal attachment on the opposite end of the frame which is removably connected to the bearing assembly. Intermediate and vertically aligned with the ends of the frame is a horizontal displacement control member which is removably connected to the bearing assembly at a point vertically above the pivotal attachment. Horizontal displacement of the horizontal displacement control member will cause a rotating of the bearing assembly about the pivotal attachment allowing clearance and lateral removal of the bearing assembly from the vertical pump system.
