Abstract
A kickover tool is for placing and extracting a valve in a mandrel having a tool body extending in a longitudinal direction and having a hydraulic piston chamber therein. A hydraulic piston is located inside the hydraulic piston chamber. A kickover arm portion is mechanically connected to the hydraulic piston, the kickover arm portion comprising a kickover arm having a tool portion. The kickover arm has a non-kicked-over position where the kickover arm is substantially coaxial with the longitudinal direction and a kicked-over position where the kickover arm is substantially non-coaxial with the longitudinal direction. The kickover arm moves to the kicked-over position upon extension of the hydraulic piston.
