Abstract

A pair of back-up members (32, 42) are inserted between adjacent projection (4) of a workpiece (2). Openings (36, 46) through the members (32, 42) are aligned with holes (6) through the projections (4). A wedge (54) is driven between the members (32, 42) and forces them against outer surface portions (5) of the projections (4) surrounding the holes (6) and radial end surfaces (9) of bushings (7) positioned in the holes (6). A mandrel (62) is pulled through the bushings (7) and the openings (36, 46) to install the bushings (7). Another embodiment of back-up members (132, 142) has a plurality of openings (136, 146) for use with a workpiece (102) having a plurality of rows of axially aligned holes (106). This embodiment is preferably used with a locator (70) which has two rods (74) for holding the holes (106) and openings (136, 146) in accurate alignment.
