If required, a steady prying force on either side of the cutter bar, spaced 180° apart, can aid in removing the blade disc assembly from the spindle shaft. C. Remove the six (6) M10 nuts connecting the spindle assembly to the cutter bar. (Figure 4-8) D. Lightly tap a screwdriver into the two slotted notches cast into each spindle housing, positioned 180° apart. Simultaneously and with equal force, press downward on the two screwdrivers. When the sealant attaching the spindle housing to the cutter bar has been broken, remove the entire spindle assembly from the cutter bar taking special care to keep dirt and debris out of the cutter bar. E. Prior to reassembling the spindle assembly onto the cutter bar (see your Bush Hog Repair Parts Catalog for the spindle assembly part number), thoroughly clean the top face of the cutter bar casing where the spindle was originally located of all old sealant, oil and dirt. F. Draw a bead of oil resistant gasket sealant (Dow Corning 735 sealant recommended by manufacturer) around the perimeter of the spindle housing opening in the cutter bar casing. G. Position the spindle assembly over the six (6) M10 bolts (ensuring that blade disc will assemble at 90° to the adjacent assembly) and join the spindle assembly to the cutter bar using the six (6) M10 nuts removed in Step C. Apply Loctite 242 thread sealant to the threads of the Figure 4-7 Optional Crop Divider Hub Cap Jam Nut Threaded Rod Cap Crop Divider Retaining Nut Output Shaft Blade Disc Assembly Figure 4-8 Cutter Bar Spindle Assembly six (6) M10 bolts and torque the nuts to a value of 62.5 - 73 ft./lbs. H. Install blade disc assembly onto the same gear assembly from which it was removed, making sure the blades of the disc assembly being installed are exactly 90° apart from both adjacent blade disc assemblies to ensure proper timing. Tighten the retaining nut to 200 ft./lbs. The outer gear housing assembly has the crop divider assembled to the blade disc assembly. The cap for the crop divider must be installed. 15 STANDARD CROP DIVIDER (Figure 4-6) Reattach the cap and cutter to the crop divider by reinstalling the four(4) capscrews through the top of crop divider and tightening securely. OPTIONAL CROP DIVIDER (Figure 4-7) Tilt cap sideways and insert cap assembly into the top of the crop divider. Insert pointed end of threaded rod into the center hole on the end of the round output shaft. Tighten cap by turning threaded rod clockwise so cap moves up on threaded rod until it fits tight into taper of crop divider. Tighten jam nut. Snap on hub cap. 4-7 CUTTER BAR REMOVAL A. Lower cutter bar to rest on the ground. B. Remove pin (Figure 4-9) and disconnect cylinder from cylinder lug. For models with cutter bar helper spring only, disconnect helper spring assembly from curtain/beam assembly. C. Detach shield and curtain/beam assembly from the gearbox/cutter bar assembly. (Figure 4-9) D. Remove belt shield rear cover. (Figure 4-9) E. Loosen tension then remove the belts. F. Remove three bolts securing sheave to gearbox input shaft. Install bolts in adjacent holes and progressively tighten to remove sheave from tapered hub. (Figure 4-11 G. Remove the two bolts securing the front mounting lug (Figure 4-10). Remove front mounting lug. Detach gearbox/cutter bar assembly from the main beam/hitch frame assembly. Figure 4-9 Helper Spring 4-8 CUTTER BAR INSTALLATION A. Install gearbox into frame, securing with front mounting lug and two bolts. (Figure 4-10) B. Install sheave (Figure 4-11) onto gearbox input shaft and key aligning with driver sheave. Alternately tighten the three retaining bolts. C. Install matched set of belts (Figure 4-11) Tighten adjusting nut until belts deflect 1/2” with 10 pounds of force applied. Rotate belt pulleys 6 complete revolutions to seat the belts into the pulleys. Tighten adjusting nut a second time until the belts deflect 1/2 “ with 10 pounds of force applied. Tighten jam nut on adjusting nut and tighten assembly pivot bolt. D. Install belt shield rear cover. Figure 4-9) E. Attach shield and curtain/beam assembly to gearbox/cutter bar assembly. (Figure 4-9) F. Pin cylinder to cylinder lug. For models with cutter bar helper spring assembly, attach spring assembly to curtain/beam assembly.
