Abstract
In accordance with an illustrative embodiment of the present invention, a kickover tool for replacing and removing valves includes an orienting section having angularly spaced dogs that are cooperable with a sleeve in a side pocket mandrel to cause orientation of the tool and to trigger longitudinal movement of a control rod. Rod movement cams an inwardly biased kickover arm outwardly to enable extension of guides that cooperate with ramps or the like in the side pocket mandrel to cause a valve coupled to said kickover arm to be inserted through a seat and latched in place in the mandrel. After the valve is seated and latched, the guides are disabled wtih response to upward force on the pivot arm. A clutch to prevent premature actuation of the kickover tool also is disclosed.
