ABSTRACT:
A remotely operated tool and tool support for positioning heat exchanger tube ends within a tube sheet of a steam generator and expanding the tube end into intimate contact with the tube sheet. The tool includes a tool head for insertion into the vertically extending tubes and a drive means which is supported horizontally by the tool support. The tool head is supported for vertical movement with respect to the drive means and right angle gear means are interposed therebetween in a vertically movable mount to permit such relative movement. Switch means responsive to the relative positions of the tool head, drive means, and right angle gear means indicate each is in a proper position to initiate or terminate the operation of the tool.
