ABSTRACT:
A device for dismantling a universal joint is provided and consists of a C-shaped housing having a fork at lower end and an abutment at upper end to fit between a first arm of a first yoke member of the universal joint. A main piston extends vertically from the housing and has a bar transversely attached to its distal end. A hydraulic mechanism within the housing will force the main piston downwardly so that the transverse bar will bear against arms of a second yoke member of the universal joint to cause a cap from a second arm of the first yoke member to disengage from a cross shaft of the universal joint.
