Abstract
An axle extraction apparatus includes a housing defining a compartment for receiving and containing a workpiece, such as a bearing, from which a component such as an axle, is to be extracted, a hydraulic actuator having a cylinder attached to one end of the housing and a piston rod extending from the cylinder and aligned with the axle for engaging and forcably extracting the axle from the bearing upon actuation of the actuator, and a back-up locking crank rotatably threadably attached to the housing and operable for engaging and clamping the bearing in the compartment. The crank has a handle for gripping to rotate the crank and a spindle threaded into the housing and a central bore through the spindle through which the axle can move relative to the bushing as it is being extracted therefrom.
