The disclosure involves a structural combination and a method for attaching a machine component such as a number of arc-shaped gear segments to a supporting segment mounting pad. As new, each gear segment is furnished with a number of openings, all of the same diameter. Initially, the mounting pad is free of openings and each gear segment is placed on the pad and used as a drilling template. After openings are drilled in the mounting pad, a number of such openings (but not all) are "opened up" by reaming and a bearing-fit bolt is inserted into the reamed openings. In repair, a new gear segment is placed at a position which spans two places formerly occupied by gear segments. Certain openings in the new segment are aligned with existing openings in the mounting pad (to receive clearance-fit bolts therethrough) and other segments openings are used to form new openings in the mounting pad. |
