A kickover tool for placing and extracting a valve in a mandrel having a hydraulic piston, a kickover arm portion mechanically connected to the hydraulic piston, the kickover arm portion being actuated by application of pressure to the piston. Upon full stoke of the piston, pressure is relieved, and measurement of the pressure relief can be used to indicate proper placement in a side pocket mandrel.
