Abstract
Roller cutters are mounted onto a cutterhead from the rear side of the cutterhead. A load transfer block is insertable between a stator portion of each cutter and a generally forwardly directed load-carrying surface on the cutter-head frame. Loads imposed on the roller cutter during boring are transmitted rearwardly from the stator to the load transfer block, and from the load transfer block to the cutterhead frame.
