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), thor- oughly clean the top face of the cutter bar casing where the spindle was originally located of all old sealant, oil and dirt.

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 assem- bled to the blade disc assembly. The cap for the crop divider must be installed.
