3. Remove cotter pin from bottom of crossbar and
remove nut and washer.
4. Refer to Figure 14
.
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
