CROSSBAR REMOVAL
1. It is necessary to gain access to bottom side of
cutter for crossbar removal. See Blocking Method
page 19.
NOTE: You will need to use either the puller screw
(Item 6, Figure 16) or a small hydraulic jack to
remove the crossbar.
2. Remove blades from crossbar as shown in Figure
15.
Figure 15. Blade Removal
3. Refer to Figure 16
.
Remove cotter pin from bottom
of crossbar and remove nut and washer.
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
(4) in nut and thread puller screw (6) into nut from
bottom. Tighten until pad is solid against gearbox
shaft. For best results, strike head of puller screw
with a hammer while tightening with a wrench.
7. For removal with a jack, attach tube to each clevis
with puller links (7), bolts (2), and nuts (3). Place
jack on tube with end of jack pressing against
gearbox shaft. Slowly apply force with jack.
NOTE: Hydraulic jack will not operate if tipped
