A wellbore tool locating system has been invented which includes a friction engager for engaging an interior of a wellbore tubular, an outer sleeve connected to the friction engager and having a slot therethrough for controlling movement of an inner body an inner body movably disposed within the outer sleeve for both rotating and up-and-down movement therein, a lug projecting out from the inner body and movably disposed in the slot, at least one key in a recess in the body, the at least one key urged outwardly by a spring therebehind, the at least one key initially held in its recess by contacting an inner surface of the outer sleeve, at least one window through the outer sleeve, and the inner body movable to align the at least one key with the at least one window to release the at least one key to move from its recess to project through the at least one window and beyond an exterior surface of the outer sleeve for engaging a profile on the wellbore tubular. |
