Figure 5.40: Center Guard Hold-Down
2. Use a feeler gauge to measure the clearance between the
center guard hold-down (A) and the knife section. Ensure
the clearance is between the following measurements:
•
At hold-down tip (B): 0.1
–
0.4 mm (0.004
–
0.016 in.)
•
At rear of hold-down (C): 0.1
–
1.0 mm (0.004
–
0.040 in.)
3. Adjust the clearance as follows:
a. Tighten nuts (D) until finger tight.
b. Turn three adjuster bolts (E) clockwise to raise the
front of the hold-down and increase clearance, or
counterclockwise to lower the front of the hold-down
and decrease clearance.
c. When all the adjustments are complete and the
specified clearances are achieved, torque nuts (D) to
88 Nm (65 lbf
∙
ft).
WARNING
Check to be sure all bystanders have cleared the area.
4. Complete the hold-down adjustments, run the header at low engine speed, and listen for noise caused by insufficient
clearance.
IMPORTANT:
Insufficient hold-down clearance will result in overheating of the knife and guards
—
readjust as necessary.
