Figure 4.287: Center Arm Cylinders
10. Loosen bolts (A) on both center arm cylinders.
11. Adjust the clearance as follows:
IMPORTANT:
Adjust both cylinder rods equally.
•
To increase clearance to the cutterbar, turn cylinder
rods (D) out of clevis to raise the reel.
•
To decrease clearance to the cutterbar, turn cylinder
rods (D) into clevis to lower the reel.
12. Ensure distance measurement (B) is equal on both
cylinders.
NOTE:
Distance measurement (B) is from the center of mounting
pins (C) to the tops of the notches in cylinder rods (D).
13. Verify that both mounting pins (C) cannot be rotated by
hand. If one of the mounting pins is free to rotate, then
adjust cylinder rods (D) as required until both cylinder rods
take the load:
•
Turn cylinder rod out of the clevis to increase the load
on the cylinder rod.
•
Turn cylinder rod into the clevis to decrease the load on
the cylinder rod.
14. Tighten bolts (A).
15.
Triple reel:
Repeat Step
to Step
for the other center reel arm.
DANGER
Ensure that all bystanders have cleared the area.
16. Start the engine.
17. Raise the reel fully.
18. Lower the reel fully, and continue holding the control button down to phase the cylinders.
19. Shut down the engine, and remove the key from the ignition.
20. Check measurements again and, if necessary, repeat the adjustment procedures.
21. Move the reel back to ensure the steel end fingers do not contact the deflector shields.
22. If contact occurs, adjust the reel upward to maintain the clearance at all reel fore-aft positions. If contact cannot be
avoided after adjusting the reel, trim the steel end fingers to obtain proper clearance.
23. Periodically check for evidence of contact during operation, and adjust clearance as required.
