(Item 6, Figure 14) or a small hydraulic jack to
remove the crossbar.

Figure 13. Blade Removal
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
(4) in nut and thread puller screw (6) into nut from

shaft. For best results, strike head of puller screw
with a hammer while tightening with a wrench.

with puller links (7), bolts (2), and nuts (3). Place
jack on tube with end of jack pressing against
