Abstract: A rod positioning tool mounts in series between a tubing string and the stuffing box of a drive head. An outer mandrel of the tool mounts to a first flange at the bottom end for connection to the tubing string below and an inner mandral mounts to a second flange for connection to the stuffing box above. The inner mandrel is slidably received within the outer mandrel with primary seals therebetween to vary the overall length of the tool using one or more actuators between the flanges, while maintaining a sealed connection between the tubing string and the stuffing box. Keys on the outer tubular mandrel are longitudinally slidable in keyways on the inner tubular mandrel to resist relative rotation between the mandrels. A secondary seal provides a sealed connection between the second flange and the top end of the outer mandrel in a fully retracted position of the tool.
