Figure 4.54: Underside of Cutterbar Spindles Installed in Cutterbar
IMPORTANT:
Right-hand discs (A) and left-hand discs (B) are timed and must be at 90° when reinstalled. Misaligned discs
could result in the following:
• Cutter blades of co-rotating discs hitting each other.
• Cutter blades of diverging discs will hitting adjacent discs.
Check clearance before tightening spindle to the cutterbar. Turn disc by hand to ensure cutter blades do not
contact each other or adjacent discs. If contact occurs, remove spindle, rotate 90°, and reinstall. Remove and
reinstall spindles as many times as necessary to achieve proper alignment.
NOTE:
Right-hand discs (A) and left-hand discs (B) are slightly offset as shown depending on which idler gear the
spindle is turning.
• Spindles that rotate clockwise have left-handed threading.
• Spindles that rotate counterclockwise have right-handed threading.
