4.5.8 Replacing Cutterbar Spindle Shear Pin
Figure 4.110: Cutterbar Spindles
To prevent damage to the cutterbar and drive systems, each
disc is attached to a spindle containing a shear pin (A).
If the disc contacts a large object such as a stone or stump, the
pin will shear and the disc will stop rotating and move upwards
while remaining attached to the spindle with a snap ring (B).
IMPORTANT:
Ensure correct orientation of the shear pins during replacement.
• Spindles that rotate clockwise have right-leading threading.
• Spindles that rotate counterclockwise have left-leading
threading.
NOTE:
Once spindle has risen due to shear pin failure, the spindle’s
bearing will become unloaded. Do NOT replace the spindle due
to excessive play. Check play after torquing spindle nut and
replacing damaged shear pins.
Figure 4.111: Spindle Nut Tool
NOTE:
A special spindle nut wrench is located under the panel on the
right side of the header. This tool is used to loosen and tighten
the spindle nuts.
