ABSTRACT:
An engine block reboring system for main bearings in which the block is mounted on a pair of rails extending laterally on a workbed and is rebored by a tool driven by a right-angle drive extension on a vertical boring machine after the position of the block has been adjusted so that the vertical axis of the boring machine spindle and the desired reboring axis are in the same vertical plane, and the proper height for the tool is set for reference, so that the bearings can be rebored by manipulating the spindle vertically and horizontally in said vertical plane with respect to the height reference. Apparatus is provided for initially properly aligning the block and keeping it in aligned position during the reboring operation.
