4.Attach a clevis (1) to each end of crossbar, using blade pins, spacers, keyhole plates, and blade pin clips.
5.Position tube assembly (5) with threaded nut (4) toward crossbar for puller screw removal or down for hydraulic jack removal.
6.For removal with puller screw, attach tube (5) to each clevis with bolts (2) and nuts (3). Place pad
