For crossbar removal, it is necessary to gain access to
bottom side of cutter. Raise cutter and securely block

hydraulic jack to remove crossbar. See Figure 25.
Loosen bolts on crossbar clamp. Remove bolt retaining
washer by prying washer up and breaking weld.
Remove washer and bolt. Remove blades from cross
-
bar (see page 20). Assemble clevises (1) to each end
of crossbar, utilizing blade pins, spacers, keyhole
plates and blade pin clips.
Position tube assembly (5) with threaded nut toward
crossbar. Install pad assembly (4) in nut on square tube
assembly.
Bolt square tube assembly to the clevises using 5/8" x
4-1/2" bolts (2). Insert puller screw assembly (6) into
square tube assembly (5) and tighten against pad
assembly (4) an gear shaft as shown. For best results,
strike head of puller screw with a sledge hammer while
tightening screw with a wrench. If crossbar has been
installed with Loctite, it may be necessary to apply heat
(greater than 500°F) to crossbar to break Loctite bond.
