A mechanical setting tool for setting a mechanically set expandable packer, including a tubular housing, and an inner mandrel extending into the interior bore of the tubular housing. There is a track and follower engagement between the inner surface of the tubular housing and the outer surface of the inner mandrel, the follower adapted to engage the track. The track comprises a circumferential component and alternating axial components that define at least one intermediate position allowing limited axial movement and a release position allowing increased axial movement. The follower moves along the track until the inner mandrel is in at least one intermediate position, with a further jarring force moving the follower along the track until the follower reaches the release position. A set of gripping elements positioned on the outer surface of the tubular expand outward upon a jarring force being exerted upon on the mandrel when the follower is in the release position. The mandrel is then free to move axially to set the expandable packer connected to the second end connection.
