Inserting the tool into the seal bore, depressing an activation button on a handle of the tool thereby actuating a hydraulic cylinder actuation means. Expanding a plurality of engagement projection fingers, locking the plurality of engagement projection fingers in place while providing an axial alignment reaction force; overcoming a first actuation force on a spring to actuate the driver ring, by a second actuation force, pulling the seal into seal bore, dwelling for approximately five seconds to fully seat the seal, breaking the circuit to the hydraulic actuation means by releasing the activation button. Withdrawing the driver ring from the seal, retracting the engagement projection fingers and withdrawing the tool from the seal bore.
