ABSTRACT:
For removing a bearing or axle bushing from an axle, a hydraulic puller comprising a pawl assembly mounted on a hydraulic pipe, an oil container attached to the hydraulic pipe at the top, a movable rod movable fastened in the hydraulic pipe at the bottom, a piston rod controlled by a hand lever to squeeze a hydraulic oil out of the oil container for moving the movable rod, and a spring to automatically push the movable rod back to its original position. Repeatedly rotating the hand lever back and forth causes the movable rod to extend out of the hydraulic pipe, and therefore, the pawl assembly is forced to pull a bearing or axle bushing out of an axle.
