Figure 4.280: Center Arm Cylinders
9.
Loosen bolts (A) on both center arm cylinders.
10. Adjust the clearance as follows:
IMPORTANT:
Adjust both cylinder rods equally.
•
To increase the clearance between the reel fingers and
the cutterbar, turn cylinder rods (D) out of the clevis.
•
To decrease the clearance between the reel fingers and
the cutterbar, turn cylinder rods (D) into the clevis.
11. Ensure that distance measurement (B) is identical on both
cylinders.
NOTE:
Distance measurement (B) runs from the center of
mounting pins (C) to the tops of the notches in cylinder
rods (D).
12. Ensure that both mounting pins (C) are
NOT
able to be
rotated by hand. If one of the mounting pins is can be
rotated, adjust cylinder rods (D) as needed:
•
Turn the cylinder rod out of the clevis to increase the
load on the cylinder rod.
•
Turn the cylinder rod into the clevis to decrease the
load on the cylinder rod.
13. Tighten bolts (A).
DANGER
Ensure that all bystanders have cleared the area.
14. Start the engine.
15. Raise the reel fully.
16. Lower the reel fully, and continue holding the control button down to phase the cylinders.
17. Shut down the engine, and remove the key from the ignition.
18. Check the reel-to-cutterbar clearance measurements again. If necessary, repeat the adjustment procedures.
19. Move the reel back to ensure that the steel end fingers do not contact the deflector shields.
20. If the reel fingers contact the deflector shields, adjust the reel upward to maintain the clearance at all reel fore-aft
positions. If contact still occurs after the reel is adjusted, trim the steel end fingers as needed.
21. Periodically check for evidence of contact during operation. Adjust the reel-to-cutterbar clearance as needed.
